In the case of tens of thousands of stamping parts produced per minute, the feeding, stamping, unloading, waste removal and other processes are often completed in a short period of time, which often leads to personal, equipment and quality accidents. Therefore, safe production in stamping is a very important issue. The safety measures in stamping are:
① Realize mechanized and automated material loading and unloading. ② Set up mechanical protective devices to prevent hand injuries. Use mold protective devices, automatic退料 devices, and manual tool material loading and unloading. ③ Set up electrical protection and power-off devices. Set up photoelectric or air curtain protective switches, double-hand or multi-hand series start switches, anti-mistake operation devices, etc. ④ Improve the clutch and braking structure so that the press's crankshaft, connecting rod, and punch can immediately stop at the original position after the danger signal is issued.
General workpieces in the process of stamping, especially in the process of cold forging stamping, the temperature will rise rapidly, and lubricating oil must be added for lubrication. If no lubricant is used and the stamping pressure is directly applied, in addition to the surface finish of the workpiece being affected, the service life of the mold will be shortened, and the accuracy will be reduced. To this end, a large amount of money will be invested in the improvement of the mold. It is precisely because of this reason that it is necessary to lubricate the stamping in cold forging stamping.
