How to improve the bending accuracy of CNC pipe bending machine?

Pipe bending machine is a very widely used equipment, such as the furniture manufacturing industry, machinery and equipment piping, automotive piping, pool handrail bending production and so on. Now the product quality requirements of many industries continue to improve, so the CNC pipe bending machine in the process of processing the need for composite bending and precision control continue to put forward new requirements. CNC pipe bending machine can use high-density sensing devices and high precision measurement system together, and can automatically correct the error.

So, how to improve the accuracy of CNC pipe bending machine?

1.Control the sprocket chain tightness, which is an important factor affecting the accuracy of bending.

2.Adjust the mold. Slight adjustment of the mold can overcome mold wear and have a good effect on improving the accuracy of the pipe bending machine.

3.Measurement of bending angle and manual intervention rebound compensation amount, this method can improve the accuracy of product production.

4.Compensation of the slider and bender head and bender arm with the accuracy of the bender, in the process of long-term use of the pipe bending machine, wear and tear is inevitable, but can be replaced by a small number of wearing parts to improve the accuracy of the pipe bending machine.

The standard measure of a CNC pipe bending machine is usually the accuracy of the bending result, which needs to be differentiated between the accuracy on the bending distance and the accuracy on the bending angle. These two parameters are not independent of each other. Depending on the use of bending, the tolerances are usually very small.

Bender equipment in the process of workpiece processing, its speed and production of products with very high precision. The machine needs to run at high speed throughout the entire process of workpiece processing, so as to effectively pinpoint the position.

Shanghai ANTISHICNC production of CNC pipe bending machine high precision, easy to operate, high productivity, favored by our customers. For example, the following head with a left and right common rotary bending CNC pipe bending machine CNC3806UE.

CNC3806UE by Y (feed), B (rotary tube), C (bending), X (shift), Z (up and down), A1 (auxiliary push) six-axis electrical servo drive. The use of electrical servo drive to avoid the defects of ordinary pipe bender precision affected by oil temperature. Automatic mold using the head of the up and down the left and right displacement principle, to avoid the feeding seat clamping pipe displacement generated by the phenomenon of shaking fittings. The head has a total of left and right rotary bending function, can bend the left and right symmetry of the workpiece and some of the complex shape of the parts, to avoid the single-rotary bender bending complex workpiece need to replace the machine to make up for the shortcomings of the bending, greatly improving the accuracy of the bending of the workpiece to save time, manpower, space.
