Manufacturing method of scroll compressor static scroll and scroll compressor static scroll

Abstract

The invention provides a manufacturing method of a scroll compressor static eddy and the scroll compressor static eddy and belongs to the technical field of mechanical engineering. Through the manufacturing method of the scroll compressor static eddy and the scroll compressor static eddy, the problem that through an existing manufacturing method, a scroll compressor fixed eddy with a notch cannot be manufactured is solved. The manufacturing method for the scroll compressor static eddy is conducted according to the following sequential steps that a blank is selected first; then a transition part is formed through first time of forging; the initial forging temperature of the blank is 460 DEG C-480 DEG C; afterwards, the transition part is immediately transferred into a second forging die for second time of forging, and the static eddy is formed; and the final forging temperature of the static eddy is 420 DEG C-440 DEG C. According to the manufacturing method of the scroll compressor static eddy, a two-time continuous forging mode and the transition part which is simple in structure and easy to form through forging are adopted, thus the full corner angles between the side faces of notches in the forging-formed static eddy and the top face of an eddy body are ensured, right-angle transition is achieved, and then the quality and production efficiency of the static eddy are ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a scroll compressor, in particular to a method for manufacturing a static scroll of the scroll compressor. [0002] The invention belongs to the technical field of mechanical engineering, and relates to a scroll compressor, in particular to a static scroll of a scroll compressor. Background technique [0003] The scroll compressor is a compressor with a compressible volume composed of a fixed involute scroll and an eccentric orbiting and translational involute moving scroll. The main working part of the scroll compressor is the gas compression part, and the air cavity is composed of a fixed scroll and a fixed scroll. [0004] The scroll compressor has a novel and precise structure, and has the advantages of small size, low noise, light weight, small vibration, low energy consumption, long life, continuous and stable gas transmission, reliable operation, and clean ga...

Problems solved by technology

Technicians try to use traditional methods to manufacture aluminum-magnesium alloy dynamic and static scrolls, but there are problems of low production efficiency and various subtle defects in the products, which in turn affect the quality of aluminum-magnesium alloy dynamic and static scrolls

[0007] For this reason, someone has proposed a method for manufacturing the aluminum alloy movable and fixed disks of a scroll compressor (application publication number CN104801646A). The applicant of this patent believes that the technical solution can improve the quality and production efficiency of the dynamic and static scroll disks; People have obtained through analysis and experiments that this manufacturing method cannot improve the Figure 4 The quality and production efficiency of the fixed scroll of the scroll compressor with the notch on the outer circular wall shown above are mainly due to the fact that the edges and corners between the side of the notch and the top surface of the disc body are arc-shaped; Technical requirements for a right-angle transition between the top surfaces of the body
