The pipe bending machine is a machine with a wide range of applications, ranging from a small part of a refrigerator to the bending of underground pipes. The upgrading of pipe bending equipment, web slitting machines, pipe cutting machines, and paper pipe machines is the first to be introduced in Japan, and it has earned a lot of dollars in this field. The four little dragons in Southeast Asia also followed Japan's lead, and have performed well in the manufacturing of packaging machinery and equipment and production lines. In the European Community, the pace of upgrading packaging machinery and equipment and production lines in Italy is much faster than other member states. With the improvement of the technical level of various industries, new requirements have been put forward for the accuracy and composite processing technology of pipe bending machines. So how does the tube bending machine sensor affect the performance of the tube bending machine? Table and machinery experts tell you:

The elbow sensor has good abrasion resistance and can work with long cycle, high precision and high stability. Therefore, the pipe bend sensor of the pipe bending machine can be installed by direct welding. The specific method is to weld the elbow sensor directly to the process pipe, which solves the problem of leakage and leakage that may occur during the steam flow measurement process.

In order to solve the problem of leakage and leakage, a type of welded orifice plate has appeared on the market. However, because the orifice plate does not have abrasion resistance, its maintenance period is only one year. Welded orifice plate is to solve the problem of leakage and leakage in steam flow measurement at the cost of loss of measurement accuracy, which is certainly not a good way. Therefore, the welded orifice plate is ultimately not widely accepted. The elbow flowmeter belongs to a differential pressure flow measurement device. It measures the flow by converting the differential pressure signal into an electrical signal through a differential pressure transmitter. The differential pressure transmitter is connected to the elbow sensor through a pressure guiding tube. Due to the existence of the pressure guiding tube, the high temperature and high pressure steam does not directly contact the signal converter (here, the differential pressure transmitter). Therefore, there is no problem that the converter is affected by high temperature and high pressure steam.

What details should be paid attention to during the use of pipe and tube bending machines?

Pipe and tube bending machines are very common in life, with advantages such as multiple functions, reasonable structure, and simple operation. But after all, they are machines, because they are designed to be used with bent metal, there is a certain degree of danger, and there is a certain degree of danger if they are not handled properly. The main shaft of the pipe bending machine is inserted directly from the upper part of the machine head during assembly. The installation is accurate and easy to maintain. The pipe bending shaft and the transmission sprocket are forged and machined integrally. In the process of pipe bending, the hydraulic arm automatically throttles the buffer before the angle set by the bending, which greatly improves the bending accuracy and quickly resets. The throttle buffer is set near the starting point during the return, which greatly improves the reset Precision and productivity. Full hydraulic drive. The microcomputer controller can preset 16 kinds of angles, and can use the foot switch of the pipe and tube bending machine to complete the entire process at one time. The design of the stiffeners on the head and bed of the pipe and tube bending machine is annealed to eliminate internal stress. The whole has sufficient strength and rigidity to prevent permanent deformation. The drive spindle is inserted directly from the upper part of the machine head during assembly. The installation is accurate and easy to maintain. In the middle, the swivel arm automatically throttles the buffer before the angle set by the bending, which greatly improves the bending accuracy and rapid reset. The return process is provided with a throttle buffer near the starting point, which greatly improves the reset accuracy and work. effectiveness. Then the staff of the bench and the machine will give you a brief introduction on the details that need to be paid attention to during the use of the pipe and tube bending machine.

1. First, make sure that the pipe and tube bending machine is normal and ready to work. A lock / tag should let you know what is safe to use. Check the date of the last inspection to see if the and tube bending machine is moving in a proper time frame Components that can be worn down over time, machinery requires a certain amount of lubricant and pressure for safe operation.

2. Remove any foreign objects before powering on. Do not move anything on the surface of the and tube bending machine. Your body may eventually start the button or a partial tilt, which will cause you great harm.

3. Adjust the machine to best suit your working range. If possible, adjust the machine or level of safety to keep your body within the safe range.

4. Use all necessary protective equipment and use all necessary safety equipment. Some machines may require operating safety gloves to better separate the user of the safety device of the squeeze point.

5. The operating machine is not suitable for the use of pipe and tube bending machines, but if you use it to bend, the machine may be damaged or malfunction to hurt you.

We all know that tube bending machines are mainly used for electric power construction, public railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration and other aspects. In fact, the specific work of pipe benders is not just bending. Certain pipeline functions can sometimes be used to disassemble some related pipeline components. If it can also be used as a hydraulic jacking machine, this can be said to be an extension of the working capacity of the pipe bending machine

So how to correctly and cleverly use the pipe bender to achieve twice the result with half the effort? The following table and mechanical experts will introduce to you how to make the pipe bender cleverly improve the work efficiency:

Generally, the pipe bending speed of the pipe bending machine has a speed level. When the pipe is small, use the fastest gear, and when the pipe is large, use the slow gear. Like the above speed adjustment method, on the control panel, follow the instructions to modify. If you want to solve the problem, it is recommended that you purchase a CNC automatic pipe bender, which can process about 1,000 pipes a day.

I believe that we usually have the habit of wearing masks when we go out, especially in spring in some densely populated areas, wearing masks can be useful to prevent some airborne diseases. But do we know? With the development of industrial automation, masks are also produced by automated machinery. The first choice of machinery is the unfolding mask machine.

Regarding the filter material of a good protective mask, the following three conditions should be met. One is that the filtering efficiency is high under the condition that the mask and the user's face are in excellent adhesion. The second is that the breath permeability is good. There are many raw materials for dust-proof mask filters, such as general fabrics, animal hair, non-woven fabrics, activated carbon felt, and other materials.

Due to the poor adhesion of the molecular structure of the gauze mask, many small damage particles will enter our lungs through the fine space of the mask. The filter material of gauze masks is mostly some mechanical fabrics. The dust-proof rate of gauze materials is low. As long as the thickness of the mask is added to achieve the effect, this makes the user feel greater respiratory resistance and the comfort of the mask becomes worse. However, not only can non-woven fabrics obstruct large dust particles after electrostatic treatment, but also the electrostatic charges attached to the surface can adsorb fine dust. The thickness of the filter material after treatment is very thin, allowing the user to breathe smoothly, and thus satisfies the three necessary conditions of the good filter material we mentioned earlier.

However, on the market, there are many masks produced by different types of folding mask machines. Many brothers do not know how to choose a mask style that meets the requirements. The masks below have several different styles. Also let you When choosing a mask, choose a function that can effectively protect human health.

First, cup-shaped masks

Cup masks are made of odorless, non-toxic, non-allergenic, non-toxic and glass top ten million raw materials. They have soft touch, high efficiency, low toxicity, deodorization, cleanness, convenience and safety.

Second, folding masks

Folding masks are a type of folding planning masks, which are easy to wear and have a common planning shape, which can ensure excellent fit with the face. It is suitable for most face shapes, and is mainly suitable for construction, stone mining, polishing, electronics, food processing, etc Dust from work is aside.

Third, medical masks

Medical masks are nationally tested. Protective mask products with high safety and cleanliness are widely used by physicians in hospitals. They are mostly disposable, convenient to use, and do not require cleaning. Compared with civilian masks, they have more protective effects against respiratory diseases.

Fourth, civilian masks

Civil masks can be divided into cotton, second cloth, activated carbon and other raw materials. The more layers of masks, the better and stronger the protective effect against their pathogens.

The masks produced by different types of mask machine equipment are different, and the production methods are also very different. Therefore, when we choose or purchase a folding mask machine, we must consider the applicable environmental conditions and ensure that we purchase An environment-friendly product mask to prevent the purchase of product masks that are not suitable for the environment, so as not to lose the outstanding mask protection effect.

How to maintain a mask machine

In modern society, due to the continuous deterioration of the natural environment and the strengthening of our awareness of protection, the market demand for disposable medical masks and protective masks is constantly expanding. Many customers are keenly aware of this business opportunity and want to enter the work of mask production. However, in view of the unfamiliarity with the mask production process, the purchase of mask raw materials, the selection of mask machine manufacturers, the plan of the mask production workshop, the working specifications of mask production, etc., when inquiring and consulting relevant information and making relevant calculations, Looks very blind and reckless.

During the production of the mask by the folding mask machine, the maintenance of the mask machine is very important. The maintenance of the mask machine can not only delay the reduction of the accuracy of the mask machine, but also reduce the probability of repairing the mask machine.

I. Appearance: The mask machine is used for wearing on the face, and some even enter the operating room. Therefore, the production of the mask must be begged to be cleaned daily. You can arrange for people to clean the work surface of the equipment and the dishes that hold masks after shutdown and power off every day. Be careful not to use water or oil. You can use other non-toxic and volatile cleaning liquids such as alcohol.

Second, the ultrasonic system: (consisting of an ultrasonic electrical box, an ultrasonic transducer, a welding head, and a connecting line) Check whether the ultrasonic system is clean, especially the ultrasonic electrical box, the ultrasonic transducer (vibrator), and the welding head (mold). It is necessary to monotonically clean without water, and the connection line is not strong. Frequently check the wear level of the ultrasonic welding head (mold) of the folding mask machine. Pay attention to whether the pointers of the voltmeter and ammeter on the ultrasonic electric box are normal.

3. Transmission system:

The mask machine transmission system includes motors, gears, reducers, sprockets, chains, conveyor belts and other components. Check whether the surface of the motor is covered with dust and other things that affect heat dissipation, and whether the gears and sprockets are oiled or attached. Is the chain tightness suitable for foreign matter, is the connecting screw of each transmission part loose? Is the lubricant of the reducer sufficient? Usually, the oil needs to be replaced once every 1000 hours to 1500 hours.

Fourth, the electrical system:

Mask machine check whether the circuit connector of the mask machine equipment is loose, and the main power line, branch signal line, etc. are worn. Ageing? Loose? Is the inside of the electric box clean and monotonous, is the exhaust fan working properly, and so on.

Five: Pneumatic system: (composed of air source filter system, air pipe, cylinder) Is there any water in the air filter inspection? (Air compressor water discharge: the area with high humidity should drain water to the air compressor every day). Check for air leaks in the trachea? Is there a leak in the cylinder? Cylinder magnetic anti-sensor orientation and operation are not normal.

Others: The equipment must not come into contact with corrosive liquids and objects, for example: sweat is very easy to cause equipment parts to rust. If the equipment is not used for a long time, it is necessary to apply anti-rust oil to the drive system and rust-prone parts of the mask machine.

Manufacturers of masks require maintenance of the mask machine equipment according to the requirements. Not only can the repair times of the mask machine be reduced, but also the working life of the imported mask machine can be supplied to the company.

How to maintain a flat mask machine

In modern society, due to the continuous deterioration of the natural environment and the strengthening of our awareness of protection, the market demand for disposable medical masks and protective masks is constantly expanding. Many customers are keenly aware of this business opportunity and want to enter the work of mask production. However, in view of the unfamiliarity with the mask production process, the purchase of mask raw materials, the selection of mask machine manufacturers, the plan of the mask production workshop, the working specifications of mask production, etc., when inquiring and consulting relevant information and making relevant calculations, Looks very blind and reckless.

During the production of masks by the flat mask machine, the maintenance of the integrated mask machine is very important. The maintenance of the integrated mask machine can not only delay the reduction of the accuracy of the mask machine, but also reduce the probability of repair of the mask machine equipment.

I. Appearance: The mask machine is used for wearing on the face, and some even go into the operating room. Therefore, the production of the mask machine requires the mask machine to be cleaned daily. You can arrange for people to clean the work surface of the equipment and the dishes that hold masks after shutdown and power off every day. Be careful not to use water or oil. You can use other non-toxic and volatile cleaning liquids such as alcohol.

It is necessary to monotonically clean without water, and the connection line is not strong. Frequently check the wear level of the ultrasonic welding head (mold) of the flat mask machine. Pay attention to whether the pointers of the voltmeter and ammeter on the ultrasonic electric box are normal.

3. Transmission system:

The drive system of the flat mask machine includes motors, gears, reducers, sprockets, chains, conveyor belts and other components. Check whether the surface of the motor is covered with dust and other things that affect heat dissipation, and whether the gears and sprockets are oiled or attached. Is the chain tightness suitable for foreign matter, is the connecting screw of each transmission part loose? Is the lubricant of the reducer sufficient? Usually, the oil needs to be replaced once every 1000 hours to 1500 hours.

Fourth, the electrical system:

Plane mask machine Check whether the circuit connectors of the mask machine equipment are loose, and are the main power lines, branch signal lines, etc. worn? Ageing? Loose? Is the inside of the electric box clean and monotonous, is the exhaust fan working properly, and so on.

Five: Pneumatic system: (composed of air source filter system, air pipe, cylinder) Is there any water in the air filter inspection? (Air compressor water discharge: the area with high humidity should drain water to the air compressor every day). Check for air leaks in the trachea? Is there a leak in the cylinder?

The mask manufacturer required to maintain the flat mask machine equipment according to the requirements. Not only can the repair times of the mask machine be reduced, but also the working life of the imported mask machine can be supplied to the company.

In modern society, due to the continuous deterioration of the natural environment and the strengthening of people's awareness of protection, the market demand for disposable medical masks and protective masks is constantly expanding. Many customers are keenly aware of this business opportunity and want to get involved in the industry of mask production. However, in view of the unfamiliarity with the mask production process, the purchase of mask raw materials, the selection of mask machine manufacturers, the planning of mask production workshops, the industry standards for mask production, etc., when inquiring and consulting relevant information and making relevant budgets, It seems blind and confused. The following are some common sense introductions to the ultrasonic mask machine to help customers who are ready to show their talents in the mask production industry to shine a little twilight in the mist and know the direction:

First of all: masks are simply divided into flat masks and three-dimensional masks in appearance. Flat masks are mostly used in the medical industry, and three-dimensional masks are mostly used for daily protection. This article is mainly for the purchase of ultrasonic plane mask machine (ultrasonic medical mask machine).

Secondly: The plane mask machine series can be divided into: inner ear band mask machine production line, outer ear band mask machine production line, and strap mask machine production line according to the different welding methods and usage methods of ear bands.

In order to select the bender with the lowest tonnage specification, it is best to plan for a bending radius greater than the thickness of the material, and use the free bending method as much as possible. When the bending radius is large, it is often based on the premise of not affecting the quality of the finished part and its future use. The selection of the pipe bending machine will not only affect the bending effect of the material, but also affect the actual production cost of the equipment. Once the selection is inappropriate, it may increase the cost. Therefore, when choosing a pipe bending machine, it is necessary to consider various factors.

First of all, it is worth noting that each part of the pipe bending machine should try to choose the model with the shortest working table and the smallest tonnage under the premise of meeting the processing tasks. At the same time, it is necessary to carefully consider the material grade and the maximum processing thickness and length. If most of the work is low carbon steel with a thickness of 16 and a maximum length of 3m, the free bending force need not be greater than 50 tons. Under the same load, the probability of deflection of the 10-foot machine table and slider will be greatly increased. This means that shorter machines require fewer shim adjustments to produce qualified parts and reduce shim The film adjustment shortens the preparation time. Assuming the thickest material is 1/4 inch, a 10-foot free bend requires a 200-ton pipe bender, while a bottomed die bend requires at least 600 tons. If most of the work pieces are 5 feet or shorter, the tonnage is almost halved, which greatly reduces the purchase cost. It can be seen that the length of the parts is very important to determine the specifications of the machine.

In order to select a tube bending machine with a minimum ton size, it is best to plan for a bending radius greater than the thickness of the material and to use free bending as much as possible. When the bending radius is large, it is often chosen without affecting the quality of the piece and its future use. The choice of pipe bending machine will not only affect the bending effect of the material, but will also relate to the actual production cost of the equipment, once the wrong choice may increase the cost. So when buying cnc tube bender, you still need to consider a variety of factors. First of all, it is worth noting that every part of the automatic pipe bending machine, in order to meet the processing tasks, the premise of the shortest workbench, the smallest tonnage of the aircraft. At the same time, careful consideration is needed of the material grade and maximum processing thickness and length. If most of the work is low-carbon steel with a thickness of 16 and a maximum length of 3m, then the free bending force does not have to be greater than 50 tons.

Under the same load, the chances of a 10-foot machine workbench and slider deflection increase significantly, which means that shorter machines require fewer gasket adjustments to produce qualified parts, and less gasket adjustments and shorter preparation times. Assuming that the thickest material is 1/4 inch, 10 feet of free bending requires 200 tons, and a pipe bending machine bottom die bend requires at least 600 tons. If most artifacts are 5 feet or less, the tonnage is almost halved, greatly reducing acquisition costs. It can be seen that the length of the part is very important to determine the specifications of the machine.
