Punching mold of compressor rack

Abstract

The invention discloses a punching mold of a compressor rack, belonging to the field of punching molds. The punching mold comprises an upper template, a lower bottom plate, an upper mold base, a lower template, a base plate, a fixing plate, a discharge plate, a male mold punch and a lower concave mold. The mold closing process is that the male mold punch moves into a concave mold groove downwards for punching after the discharge plate presses the material, the male mold punch moves upwards, the discharge plate moves upwards and an ejector in the lower concave mold ejects a workpiece to finish the punching process. Compared with an ordinary mold, the punching mold is more accurate, so that the condition that the workpiece does not generate a crimped edge in a side hole punching process when large-size punching is carried out by a central male mold punch is ensured; the punching mold has the advantages of low processing cost, low usage amount of the mold, high processing efficiency and one-time punching; and furthermore, the punching mold also has the advantages of being simple in structure and easy to operate.

Description

technical field [0001] The invention belongs to the field of stamping dies, in particular to a punching die for a compressor frame. Background technique [0002] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The application fields of sheet metal parts are extremely wide, and they penetrate into all aspects of the manufacturing industry. Sheet metal forming is mainly realized by stamping dies. Using the stamping process, it has a series of advantages such as high precision, high efficiency, good quality, cost saving, material and energy saving. [0003] An existing compressor frame has a large center hole and a small side hole. Therefore, multiple processes are required to process the center hole and the side hole in the punching process to avoid simultaneous punching. The holes cause stress concentration on the workpiece and cause the workpiece to be scrapped. However, the processing of multi...

Problems solved by technology

[0003] An existing compressor frame has a large center hole and a small side hole. Therefore, multiple processes are required to process the center hole and the side hole in the punching process to avoid simultaneous punching. The holes cause stress concentration on the workpiece and cause the workpiece to be scrapped. However, the processing of multiple processes increases the cost of mold manufacturing and reduces production efficiency, which is not conducive to the long-term development and profitability of the enterprise.
