Pipe bending machines can be roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, Manual Pipe Bender, Electrical Tube Bender and so on. It is mainly used for electric power construction, public railway construction, pipeline laying and repair of boilers, bridges, ships, furniture, decoration, etc. It has many advantages such as multi-function, reasonable structure and simple operation. In addition to the bending function, the machine can also be used as a hydraulic jack. Compared with the CNC bending equipment, it has the advantages of low price and convenient use, and it occupies the leading position in the domestic tube bending machine market.

The pipe bending machine mainly adopts the structure of sheet metal bending machine; the full-closed numerical control system of the bending machine, two grating scales and one photoelectric encoder detect and feedback in real time, and the stepping motor drives the screw to form a full closed-loop control. Two grating scales; a pair of back gauges and a pair of sliders for real-time detection and feedback correction; the photoelectric encoder detects the feedback of the position of the cylinder dead stops to the numerical control system.

3. The upper die adopts a quick clamping device, and the lower die adopts a wedge wedge deformation compensation mechanism.

4, with multi-step programming function, can achieve multi-automatic operation, complete multi-step parts one-time processing, improve production efficiency.

First, the bender is actively controlled by the NC program, and in the course of work, manual intervention is generally not required, which eliminates the operator's artificial errors or errors;

Secondly, the mechanical structure of the pipe bending machine is planned and produced according to the requirements of the precision machine tool. High-precision transmission components such as ball screw and tumbling guide are selected, and the rigidity, thermal stability and vibration resistance are good;

Third, the pulse equivalent or minimum setting unit of the servo drive system can reach 10 corps m to 0.5 Pm. At the same time, most of the work uses closed-loop or semi-closed loop control with detection reaction, with error correction or compensation function, which can be further Progressive accuracy and stability;

Fourth, the CNC machining center has a tool magazine and an active tool changer, which can complete the multi-faceted and multi-step machining of the workpiece after one clamping, and minimize the influence of the clamping error.

2. Flexible initiative, with a wide range of habits

Because of the selection of NC program control, the general-purpose tooling is used in the process. As long as the NC program is changed, the active processing of new parts can be completed. Therefore, it can be used to the requirements of continuous upgrading of products in the current market, and solve various varieties. And the issue of active production in medium and small batches.

3. Can complete the processing of complex parts

Because the pipe bending machine uses the computer interpolation and multi-coordinate linkage control skills, it can complete any trajectory movement and process any complex shape of the space surface, which can be conveniently completed such as propeller, steam turbine blade, car shape stamping die, etc. Processing of various complex surface parts.

4. High production efficiency

The pipe bending machine can reduce the maneuvering time and auxiliary time required for the processing of parts to the maximum limit, and significantly improve the production efficiency.

First, the feed motion and the main motion of the bender are stepless speed regulation, and the speed adjustment range is large. Therefore, each process can select the best cutting speed and feed speed;

Second, good structural rigidity and vibration resistance allow the machine to use large cutting amounts and strong cutting;

Thirdly, it is generally not necessary to stop the inspection of the workpiece, thereby effectively reducing the downtime in the machining of the machine tool;

Fourth, the moving parts of the machine tool adopt the active acceleration and deceleration method in the positioning, so the high idle motion speed can be selected, which greatly saves the auxiliary movement time;

Fifth, the machining center can choose the method of active tool change and active exchange workbench. The workpiece can be multi-faceted and multi-processed in one time, which greatly reduces the auxiliary moments such as workpiece clamping and tool setting.

Sixth, the processing steps can be gathered to reduce the turnover of parts, reduce the number of equipment and plant area, and bring great convenience to the dispatching of production.

5. Reduce labor intensity and improve working conditions

Because the operator of the pipe bending machine mainly uses the operation panel to operate the active machining of the machine tool, the labor intensity of the operator is greatly reduced, the production conditions are improved, and multiple machine tools can be easily handled by one person.

6. Conducive to modern production and handling

The pipe bending machine is used for processing, which can conveniently and accurately calculate the processing time of the parts or carry out active machining accounting, which can accurately calculate the production and processing costs, and is beneficial to the scientific processing of the production process. The pipe bending machine is the basis of advanced production systems such as computer aided planning and production, group control or distributed control, flexible production system, and integrated production system of accounting machine.

Nowadays, the economic level is becoming more and more agile, and it is still making progress. The demand for automobile production, industrial equipment and transportation facilities is constantly being added. The presentation of automatic bending machine has brought great people. Convenience and surprise, let's talk about some of the advantages of the fully automatic pipe bending machine.

First, high positioning accuracy, good operability, easy to repair

The positioning is highly accurate, and it can be positioned very accurately. It can quickly find out where the fault is presented during repair and it is quickly repaired.

Second, the automatic tube bending machine method is more efficient

Basically, all the steps are made by the machine itself, and there is no need for too many people to operate, which can save a part of the cost.

Third, the operator can work with a brief training

Since the operation of the automatic pipe bending machine is very simple, the operator can go to work after a brief training, which is very time-saving.

These are some of the strengths of a fully automatic pipe bender, which is why a growing number of people are picking it up for a very important reason.

During the working process of the special frequency cooling tower of the bender, the cooling medium (soft water, oil or other liquid) is driven by the main circulation pump to circulate between the heat exchanger and the cooling equipment, and the spray water is evenly sprayed on the heat exchanger. A uniform water film is formed on the outer surface of the heat exchanger, and the cold air enters the tower from the air inlet below the tower body, and flows back through the heat exchanger surface with the spray water. In this process, there are two heat exchange methods, namely, cold The heat transfer between the air and the cooling medium and the heat exchange of the transpiration of the spray water, the hot and humid air after the heat is absorbed by the fan to the atmosphere, and the rest of the spray water flows into the water tank at the lower part of the tower body, and is then transported by the water pump. To the spray system. In this way, the cooling medium in the heat exchanger is cooled and cooled.

1. Bending machine induction heating and metal melting equipment, such as: high and medium frequency quenching equipment, medium frequency power supply and electric furnace, induction diathermy furnace, holding furnace cooling, industrial solution cooling, such as quenching liquid, electroplating liquid, etc.

2. Cooling of various reactors and condenser circulating water in the chemical industry.

3. Cooling of large motors, diesel engines, rectifier equipment, electric welding equipment, hydraulic stations and continuous casting equipment.

4, metal die-casting molds, injection molds and other large mold cooling.

Today, with the development of scientific and technological skills, the pipe bending machine equipment is now more and more sophisticated in terms of quality and skill in the pipe processing machinery such as hydraulic pipe bending machine and automatic pipe bending machine and pipe cutting machine. It's not like the birth of a new product and new skills, we are all in the state of exploration, so the performance of the machine is relatively fragile, but today's pipe processing equipment is stable and regular, so After purchasing the machine tool, you only need to carefully maintain the machine tool, which can be used for a long time.

But what problems do the bending opportunities often present in daily use? In fact, these problems have already been mentioned in the previous log skills article. Today, we are talking in the old saying, there is usually a hydraulic area where the problem is caused. Because the machine is bent, the pipe is cut by a metal circular saw. Many small iron pins. If these iron pins are not cleaned, they will be directly processed into the bending machine to process the elbows. Many of the bending machine molds have a core rod tortuously. Because the fullness is not high enough, they will wrinkle or collapse. And so on.

In this way, when the pipe bender inserts the pipe into the mandrel, the small iron pin will fall out, and the iron pin that has not been trimmed will fall into the fuel tank inside the fuselage. We all know that the hydraulic pipe bender selects the oil pump input hydraulic pressure. The oil is supplied to the hydraulic power by a solenoid valve. Therefore, most of these iron pins will be filtered by the filter screen inside the oil inlet pipe after entering the fuel tank, but a small part of the iron pin will enter the oil pump, so that the iron pin sucked into the oil pump will enter the electromagnetic field. Inside the valve, these iron pins are blocked by the hydraulic solenoid valve due to the inability to flow in the solenoid valve, and the hydraulic oil cannot flow, which may cause a corresponding malfunction, resulting in the hydraulic bender not working properly.

Even if this phenomenon is presented, there is no need to panic. Just press a button on the control panel to manually press a certain action, then look at the indicator light on the solenoid valve to see which solenoid valve is not working, and then close the movie. Then use a 4mm Allen key to remove the solenoid valve attached to the oil separator. After cleaning the solenoid valve with clean fire oil, clean the inside with an air gun and clean the iron pin inside, then install it and handle it.

The actual operation of the pipe bending machine is very convenient. It only needs to train the operator slightly for a period of time. During this period, the semi-automatic pipe bending machine is simpler, and the CNC pipe bending machine is still in demand because of the many parameters that can be set. Have a certain foundation.

The pipe bending machine uses the popular language to explain the equipment used to bend the pipe. It can be seen in our daily life as seats, fitness equipment, fences, etc. As long as the straight pipe needs bending, it is required to use the elbow. machine.

Nowadays, the common bending machines in the factory include manual tube bending machine, semi-automatic hydraulic tube bending machine and CNC tube bending machine (automatic tube bending machine). During this period, the manual tube bending machine has been gradually replaced by speed and efficiency. Replaced by semi-automatic pipe bending machine and CNC pipe bending machine.

The operation principle of the pipe bending machine: the pipe bending machine comprises a bracket, a working table and a clamping plate, the working table is placed on the bracket, the working table is composed of a base and a pressing plate, and the base is connected with the clamping plate through a hinge, and the base is composed of a seat shell and a coil It is composed of a cover plate, and the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. When in use, the coil is energized by the wire, and after the power is applied, gravity is applied to the pressure plate, thereby completing the clamping of the thin plate between the pressure plate and the base. Because of the electromagnetic force clamping, the pressure plate can be made into a variety of workpiece requirements, and the workpiece with the side wall can be processed, and the operation is also very simple.
