Workpiece insulating detection mechanism in pneumatic and hydraulic punching machine

Abstract

The invention discloses a workpiece insulating detection mechanism in a pneumatic and hydraulic punching machine. The workpiece insulating detection mechanism is arranged between an upper mould (1) and a lower mould (2), wherein the upper mould (1) is fixed on a main punching shaft; and the lower mould (2) is fixed on a punching machine operating console (3). The workpiece insulating detection mechanism is an insulating detection circuit consisting of a power supply electrode, an insulating detection relay (K2), a lower mould (2), a workpiece (100) placed on the lower mould, an upper mould (1), a main punching shaft and an earth electrode; the lower mould (2) and the punching machine operating console (3) are insulated and fixed; and the lower mould (2) is fixed on a lower mould holder (11) which is fixed with the punching machine operating console (3) through an insulating plate. The invention can effectively prevent the mistaken punching operation of the punching machine, thereby preventing the hidden troubles for operation and improving the operation efficiency.

Description

technical field [0001] The invention belongs to a safety detection device for stamping processing equipment, in particular to a detection mechanism that can automatically detect that a stamping machine touches a workpiece during the stamping process using a gas-hydraulic hybrid power. Background technique [0002] The upper mold 1 on the stamping machine is fixed on the stamping spindle (such as figure 1 As shown), the stamping spindle is started by the stamping cylinder for stamping, and the workpiece 100 is placed on the lower die 2 on the press console 3. During the stamping process, the operator needs to operate the workpiece by hand. When some workpieces are very large, the operator can It is safer to operate by holding the side of the workpiece and away from the stamping direction of the stamping cylinder. However, some workpieces are small in size, and the operator needs to hold the workpiece with his hands and punch it on the console. The position of the hand and th...

AI Technical Summary

Problems solved by technology

However, some workpieces are small in size, and the operator needs to hold the workpiece with his hands and punch it on the console. The position of the hand and the punch is relatively close. Press the foot switch, the punch must be pressed down, causing personal injury

Analysis of the cause: the operator accidentally put his hand under the punch, and accidentally stepped on the foot switch, and the punch was pressed down, causing personal injury
