Title: Stroke control device press brake
Inventor: ADACHI JUNJI
IPC: B21D5/02
Filed: 1988-07-15
Abstract: PURPOSE:To keep the high bending accuracy of a plate material by sensing through a load sensor a time when a punch has come into contact with the plate material, computing the contact position through a stroke sensor and controlling the amount of indentation of the punch. CONSTITUTION:The punch 3 forces the plate material 1 into a groove 20 of a die to bend the plate material 1. When the punch 3 is lowered by hydraulic pressure supplied from a hydraulic ram 4 and comes into contact with the plate material 1, the value of the hydraulic pressure increases quickly. This change is detected by the load sensor 5 and the position of the punch 3 is known by the stroke sensor 7. The control computing circuit 8 requires a distance from the upper surface of the die 2 to the tip of the punch 3 and the plate thickness and computes a suitable amount of indentation. The punch 3 is lowered by a necessary amount based on the output valve of the stroke sensor 7. A necessary, accurate bending can be carried out without providing a special plate thickness measuring device.
