CNC bending machine slider conversion of the reasons for long stopping time

The use of bending machine for material operation, requires you to master the machine and equipment parameters, in the process of setting to pay attention to the equipment processing margin parameters to do a good job of setting, and then in accordance with the requirements of the material processing, so as to ensure that the margin parameters in the processing process in line with the requirements of the provisions, not only can improve the efficiency of the equipment. Can also extend the service life of the machine.

Advantages of CNC bending machine processing products.

We all know that the application of CNC bending machine is now very widespread, why so many manufacturers are choosing CNC bending machine for processing?

1. Good flexibility

CNC bending machine processing after good flexibility, without tools and molds, combined with CAD / CAM technology, can cut any shape, size of the plate, especially suitable for multi-species, small batch, the shape of complex parts cutting.

2. High processing efficiency

Bending cutting for non-contact processing, no mechanical punching impact, no tool and die wear phenomenon, no mechanical punching down the lap, workpiece closely aligned, can save 20%-30% of the material, cutting once formed, no subsequent processing.

3. High precision

Bending cutting kerf narrower and more polished, no rounded corners and mechanical downgrading often burr; heat-affected zone, thermal stress and thermal deformation are small.

CNC bending machine slider conversion stopping time is long what causes?

1. The upper chamber of the cylinder inhaled air, pressure build-up time is long.

2. Liquid-filled valve or self-priming pipeline flow is small, or the slider fast down too fast and cause suction vacuum.

3. The liquid filling valve is not completely closed, the pressure in the upper chamber is slow to reduce.

4. After the slow down valve gets power, the liquid filling valve is closed and the upper chamber can not absorb oil.

5. The proportional valve is not in the right position, resulting in different openings and out of sync.

6. Will be fast down the speed to reduce the test there is no pause.

7. The size of the fast down pressure has an impact on the liquid filling valve closure, excluding the fast down pressure.

8. Work into the pre-delay stage pressure parameter adjustment.

9. Liquid-filled valve control line damping hole is too small, the formation of differential pressure.

10. CNC system parameters, slow down before the delay.

11. CNC system parameters, slow down the gain parameter reduction.

Bending machine finishing margin to be determined by analytical calculation method. The factors affecting the finishing margin need to use the formula and certain test materials, a comprehensive analysis and calculation to determine its finishing margin, with this method to determine the finishing margin is more economical and reasonable, but must have a more complete and reliable test information.
