There are two main methods to measure the radius of pipe bending machine:
1. A more scientific method is to use the Pythagorean theorem, which can actually be used to calculate *. The process is also very simple. First, measure the distance between the two ends of the bend, then assume a right angled triangle, and then apply the Pythagorean formula. This way, it is easy to scientifically calculate the accurate radius of the bend.
2. A more reliable and practical method, but not very practical: first compare the radius of the paper shell circle with that of the bent pipe, and repeatedly adjust the size of the paper shell circle until it matches the radius of the bent pipe. The bending machine then measures the diameter of the paper shell circle with a ruler and converts it into the radius of the bending pipe. Usually, large torque is obtained through a variable speed mechanism, so that ordinary motors can handle it, unless the current simplicity of the pipe material is very cost-effective.
The torque and speed obtained in this way can depend on the actual situation. The servo drive is installed in the electrical control box, with one servo drive controlling each AC servo motor that can rotate the machine shaft. For example, the feeding shaft and angle shaft, each servo driver can be checked by its own display to determine its effectiveness. If the drive pipe bending machine is not in operation or has been overloaded, check the display of this driver. At this time, it will not display or issue an alarm message. In this situation, the machine will not operate.
Strong bending ability and high bending quality. The new type of pipe bending machine has a diameter, thick wall, and radius range that is 50% higher than the original pipe bending machine.
The automation of the bending process has been achieved, with high processing efficiency. When used for the original processing of pipe blanks, the entire bending process is manually operated by workers, and the speed of the bending die in and out is the same, resulting in low work efficiency. The new pipe bending machine adopts programmable control, making the bending process automatic. By adjusting the volume and speed, the bending die can be smoothly bent and quickly reset, greatly improving processing efficiency and reducing the labor intensity of workers.
The bending process has high precision. There was originally no angle control device, and the size of the bending angle was solely determined by the operator's visual inspection. The bending accuracy was only ± 5 °, which is difficult to meet the precision requirements of bending products. The new pipe bending machine adopts a rotary encoder and Coco programming controller to automatically and accurately control the bending angle, with an accuracy of ± 1 °, fully meeting the accuracy requirements of pipe bending products.

1. Look: It is to visually observe whether the hydraulic fittings and electrical components selected by the tube shrinking machine are products or produced by regular manufacturers;
Whether it is regular, whether the design of the pipeline of the oil station is reasonable, and whether there is oil leakage at the connection. If the above passes the visual inspection, the next step can be carried out.

When bending with CNC automatic pipe bender, the bending radius of the pipe bender is 0.156 times of the opening distance of the die. During the bending process of the free pipe bender, the opening distance of the die should be 8 times the thickness of the metal material. For example, when forming 16 gauge mild steel with a 1/2 inch (0.0127 m) opening pitch, the bending radius of the part is about 0.078 inches. If the bending radius of the pipe bender is almost as small as the thickness of the material, it must be formed with a bottom concave die. However, the pressure required for forming a concave die with a bottom is about 4 times greater than that of a free pipe bender. If the bending radius of the pipe bender is less than the thickness of the material, a punch with a corner radius of the front end less than the thickness of the material must be used, and the bending method of the imprinted pipe bender must be resorted to. In this way, 10 times the bending pressure of the free bender is required. In the case of free tube bending, punches and dies are machined at 85° or less (a little bit is better). When using this set of dies, pay attention to the gap between the punch and the die at the bottom end of the stroke, as well as the excessive bending of the bending machine that is sufficient to compensate for the springback and keep the material at about 90°. Typically, the rebound angle produced by the free bender bending die on the new bender is ≤2°, and the bending radius of the bender is equal to 0.156 times the opening distance of the die. For the bending of the bottom die bender, the mold angle is generally 86 ~ 90°. At the bottom end of the stroke, there should be a gap between the convex and concave dies that is slightly greater than the thickness of the material. The forming angle is improved because the tonnage of bending of the bender with a bottom die is larger (about 4 times that of the free bending), which reduces the stress that usually causes springback within the bending radius of the bender. The bending of the embossing pipe bender is the same as the bending of the bottomed die bender, except that the front end of the punch is processed into the required bending radius of the pipe bender, and the convex and concave die gap at the bottom of the stroke is less than the thickness of the material. Springback is essentially avoided by applying enough pressure (about 10 times the bend of a free pipe bender) to force the front end of the punch into contact with the material. In order to select a low tonnage specification, plan for a bending radius that is larger than the thickness of the material, and use the free bending method as much as possible. When the bending radius of the pipe bender is large, it often does not affect the quality of the finished part and its future use.

At the beginning of each day's work, a comprehensive inspection of the pipe bending machine should be carried out to achieve a comprehensive understanding of the equipment status. The inspection work mainly involves a preliminary inspection of the mold, oil cylinder, mechanical parts, and circuit system of the pipe bending machine, to see if there are any abnormalities in each mechanism, as well as whether there are any debris on the work site. There should be no objects within the rotation range of the bending arm.1、 Preparation before operation1. Check the water cooling system of the pipe bending machine to see if there is any water leakage in the inlet and outlet pipes. If so, identify the cause and repair it to normal. Is there any oil stains in the cooling circulating water pool? The structure of the cooler of the hydraulic pipe bending machine is that the hydraulic oil flows through the entire body and circulates in and out, while the cooling water flows in and out of the copper pipe to achieve the cooling purpose. If oil stains appear, it indicates that there is leakage inside the cooler. It should be promptly checked and replaced to avoid affecting the hydraulic system of the entire pipe bending machine.2. Check if there are any objects on the pipe bending machine that are unrelated to the pipe bending. If there are any, they should be removed in a timely manner to avoid affecting the normal operation of the equipment.3. Check the oil filling holes of the hydraulic pipe bending machine and add lubricating oil. Insufficient or insufficient oil can cause serious wear and affect the accuracy of the equipment.4. Check if the protective device on the hydraulic pipe bending machine is loose. If any abnormalities are found, they should be dealt with before starting the machine5. Check the working area of the pipe bending machine and clean any items that may hinder the work. There should be no oil stains or water stains on the ground to ensure the cleanliness of the workplace.6. During the start-up and trial operation, check whether the mechanical operation is normal, whether the electrical switches are sensitive and effective, and only after everything is normal can it work7. Labor protection must be worn according to regulations, and gloves are strictly prohibited when operating equipment8. Select the mold according to the process requirements of the processed product, check and confirm whether the installation of each mold and fixture is normal

With the development of modern technology and the improvement of the industrial level, the development and research of CNC numerical control pipe bender, three-dimensional hydraulic pipe bender and other high-performance pipe benders, these high-level pipe benders are generally driven by three main driving methods: motor drive, hydraulic drive, motor hydraulic hybrid drive.
1. Motor drive In today's modern industry, most of the power sources of mechanisms and equipment use motor drive methods to provide power for the basic actions of the entire equipment. The motor provides the source power, and there are many ways to transmit the power, such as the gear, rack, cam, connecting rod and other mechanisms can be driven by the motor, and the pipe bender that meets the requirements is designed according to the situation. 2. Hydraulic drive With the continuous development of industrial technology, hydraulic transmission technology is one of the fastest developing technologies in machinery and equipment, especially in recent years, it has entered a new stage of development. The hydraulic transmission and control system is widely used in all walks of life because of its advantages of large transmission power, control accuracy, fast response speed and easy to realize the integrated control of motor and hydrum. The hydraulic pipe bender powered by hydraulic pressure is a new type of pipe bending mechanism, which has the advantages of reasonable structure, convenient operation, safe operation, fast loading and unloading and multi-purpose of one machine. 3. Motor-hydraulic hybrid drive Although the hydraulic elbow has the advantages of large transmission power, high control accuracy and fast response speed, it also has some shortcomings, such as: because the operator has too many actions, the output power is low; The machine has large wear and tear and shortens the service life; The required operators are large, the labor cost is large, and the product cost is high. Therefore, in further discussion, it is proposed to adopt motor-hydraulic hybrid drive, so that the most reasonable driving method can be used to reduce the production cost, increase the production power and improve the machining accuracy in the respective advantages of the motor and hydraulic.
