Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like figure 1 Shown, a kind of refrigeration compressor piston parts cold heading forming manufacturing method, comprises the following steps:

[0018] (1) Use the cutting mechanism of the multi-station forming machine to cut the metal raw material rod into the required length metal segment 5, and transport it to the next station;

[0019] (2) The metal segment processed in step (1) is pressed into the first die opening through the first front punch, and the A end 1 of the metal segment is subjected to cold heading shaping, so that the A end of the metal segment forms a rounded corner with a radius of 4mm , and then transported to the next station through the ejection of the first rear punch;

[0020] (3) The metal segment processed in step (2) is pressed into the second die opening by the second front punch for cold hea...

Abstract

The invention relates to a cold heading forming manufacturing method for a piston part of a refrigeration compressor. Products can be formed by a cold heading multi-station forming machine through multiple dies at a time. The method includes the first step of cutting off, the second step of shaping one end, the third step of shaping the other end, the fourth step of reshaping, the fifth step of completing positioning of all notches and the sixth step of forming broaching products. The piston part of the refrigeration compressor is produced by the multi-station forming machine, the manufacturing cost is low, machining is convenient, the product weight is low, energy saving and consumption reduction can be achieved in the working process of the refrigeration compressor, the environment cannot be polluted, and pollution is small in the operating process of workers.

Description

technical field [0001] The invention relates to a method for manufacturing a piston part of a refrigeration compressor. Background technique [0002] The piston part of the refrigeration compressor is a necessary part for the work of the refrigeration compressor. In the prior art, the piston part of the refrigeration compressor is manufactured by powder metallurgy pressing and high-temperature sintering to produce a product blank and then finely processed. This kind of manufacturing method has high manufacturing cost, heavy product weight, high energy consumption for compressor work, and serious environmental pollution, and workers are prone to occupational diseases when operating the powder. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a cold heading forming manufacturing method for a piston part of a refrigeration compressor. [0004] The technical scheme that the present invention solves its t...
