Description
Technical Field
The utility model relates to a punching press technical field, in particular to mould buffer gear in secondary punching press.
Background
An upper die in the existing stamping equipment is fixed on a working piston of an air cylinder through a die fixing device, and under the action of working pressure, force can be directly transmitted to the head of the upper die, so that the requirement of stamping a workpiece is met. The structure is simple, practical and stable, but the biggest disadvantage is that when the upper die moves downwards, once the upper die contacts any object or meets any resistance, a force stroke is generated. Therefore, in case of an operational mistake to touch human hands or other objects, a personal accident or an equipment accident may be caused. Particularly, when the secondary stamping is carried out, the die works up and down for many times, so that accidents caused by contact with any object or force stroke caused by any resistance are avoided, and the requirement on the buffering of the die is high.
