Features and functions of hydraulic CNC punching machine
- 1. The feed motion of hydraulic CNC punch press has high-speed intermittent, and reasonable control algorithm can reduce the appearance of undesirable phenomena such as shock, oscillation, overtravel and out-of-step. Acceleration and deceleration control after interpolation. Based on the analysis of various acceleration and deceleration control methods such as straight line, exponential curve and conventional S-curve, it is suitable for a dedicated control system based on a simplified 5-segment S-curve acceleration and deceleration control method.
- 2. From the perspective of the practicability of the hydraulic numerical control punch, the special processing functions commonly used in the actual stamping operation are analyzed and realized. In the loading subroutine, steps such as the establishment of the workpiece coordinate system, the setting of Hareka parameters, the treatment of special plate conditions and the determination of the pre-pressing feed position are carried out to ensure the positioning of the plate under various conditions; when the length of the processed plate exceeds the stroke of the punch , Use the developed repositioning function to realize the stamping of large plates; in order to ensure that the clamp will not be hit by the punch during the stamping process, a clamp protection area is established based on the detection of the position of the clamp; Develop special processing instructions for punch presses to realize the functions of fixed cycle stamping and online modification of stamping parameters.
