Problems solved by technology

The sealing requirements of the bulkhead work are very high, and it must be matched with the water hole, and the strength and roundness of the material are required to be high. The ordinary bulkhead material is stamped from iron or aluminum plates. At the moment, the strength is uneven, the surface of the bulkhead is deformed, resulting in a roundness that cannot meet the requirements, and the bulkhead does not fall in time after stamping, causing the stamping head to get stuck, requiring shutdown for maintenance

Abstract

The invention discloses a blanking head punching knife. The punching knife includes an annular body, a vertical groove is arranged on the side of the annular body, a connecting plate is arranged on the top of the annular body, and a connecting hole is arranged on the connecting plate. The inner wall of the body extends downwards to form a cutting edge. A spring is arranged inside the annular body. The upper end of the spring is connected to the back of the connecting plate, and the lower end of the spring is connected to a rebound block. The height of the rebound block is higher than the bottom of the ring body. The present invention The structure is simple, the stability is good, the cost is low, the assembly and replacement are easy, the mold release speed is fast, the strength and roundness meet the requirements, and the work efficiency is high.

Description

technical field [0001] The invention belongs to the field of stamping dies, and in particular relates to a blanking punching knife. Background technique [0002] During the assembly process of the engine block, the bulkhead assembly needs to be embedded outside the side water channel. The sealing requirements of the bulkhead work are very high, and it must be matched with the water hole, and the strength and roundness of the material are required to be high. The ordinary bulkhead material is stamped from iron or aluminum plates. At the moment of punching, the strength is uneven, the surface of the punching head is deformed and the roundness cannot meet the requirements, and the punching head does not fall down in time after stamping, causing the punching head to get stuck and need to be shut down for maintenance. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a blanking head punching knife, which has the advantages...
