Joint punching machine

Abstract

The invention relates to machining equipment, and discloses a connector punching machine which comprises a rack. A feeding mechanism; the punching mechanism comprises a punching table fixed to the rack and a punching head installed on the rack in a sliding mode. A cutting and conveying mechanism; wherein the surface, right facing the punching head, of the punching table is provided with a punching die hole allowing the small metal sections to be embedded therein, and the cutting and conveying mechanism conveys the small metal sections to the position where the punching die hole is located after cutting off the metal bar and enables the small metal sections to be pushed by the punching head to be squeezed into the punching die hole; according to the method, bar conveying, cutting, transferring, punching and discharging are integrated, a refrigerator connector rough blank can be formed at a time through punching, compared with cutting machining, clamping errors are reduced, punching is conducted after heating, on one hand, metal can be softened, deformation and cracking can be reduced, the forming precision can be improved, and on the other hand, the production efficiency is improved. And on the other hand, the forging and pressing effect can be generated in the punching process, so that the refrigerator rough blank has better mechanical properties after being formed.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a joint punching machine. Background technique [0002] Equipment such as air conditioners and refrigerators are collectively referred to as refrigerators. For refrigerators, the refrigeration system is mainly composed of compressors, refrigerant pipes and heat exchangers. Special refrigerator joints are required for connection between pipes and heat exchangers. Threaded connections are generally used between the refrigerator joints and various components of the refrigeration system. In order to facilitate the screwing of the refrigerator joints, the refrigerator joints are generally connected The shape of the machine is machined into a hexagon or other similar shape to facilitate the cooperation with the wrench. [0003] For the refrigerator joint, the main processing process is to cut the metal bar into small sections, and then use the machine tool to cut the met...

AI Technical Summary

Problems solved by technology

Since the hexagonal structure has many processing surfaces, the rough blank of the refrigerator joint needs to be clamped multiple times in the case of machine tool processing, and there must be precision errors between different clamping surfaces, which leads to the completion of the processing of the refrigerator joint. Afterwards, there are defects of low assembly accuracy
