Abstract

The invention relates to a lock catch plate punching die. The lock catch plate punching die comprises an upper die assembly and a lower die assembly which are connected to each other. The upper die assembly is provided with a punch (9), and the punch (9) is provided with a die cutter opening. A lower die inlet block (10) for assisting punching is arranged at the position, corresponding to the punch (9), in the lower die assembly. A workpiece (11) to be punched is fixedly arranged on the lower die assembly. A stripping plate (5) is arranged below the upper die assembly. Nitrogen springs (12) for assisting stripping are arranged between the stripping plate (5) and the upper die assembly. A lower die cushion block (13) connected with the lower die inlet block (10) is arranged below the lower die inlet block (10). Compared with the prior art, the lock catch plate punching die has the beneficial effects of being high in production efficiency, good in product quality, low in maintenance cost and the like.
