Embodiment Construction

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0023] like figure 1 and figure 2 As shown, the cross ring blank 1 is annular, and the cross ring blank 1 includes a ring portion 1a and four key bodies 1b, and the four key bodies 1b are evenly distributed in the circumferential direction around the axis of the ring portion 1a; The two key bodies 1b face upward, the other two key bodies 1b face downward, and the two upward key bodies 1b and the two downward key bodies 1b are staggered; most of the key bodies 1b are located outside the ring portion 1a, The key body 1b is not only directly connected to the upper surface of the annular portion 1a, but also connected to the outer surface of the annular portion 1a through the key root portion 1c.

Abstract

The invention provides a method for manufacturing a cross ring of a scroll compressor, and belongs to the technical field of compressors. The method solves the problems that in the case of an existingcross ring manufacturing method, the yield is low, the production efficiency is low and the manufacturing cost is high. The method for manufacturing the cross ring of the scroll compressor is performed according to the following sequential steps of firstly, cutting a round tube into a circular ring-shaped blank according to the required height; secondly, heating the blank, moreover, putting the blank into a pre-forming die for extrusion molding, then obtaining a rough blank, and forming four pre-forming portions corresponding to protruding keys in the cross ring in position on the outer sidesurface of the rough blank; and thirdly, heating the rough blank, moreover, putting the rough blank into a fine forming die for extrusion forming, and then obtaining a fine blank. According to the method for manufacturing the cross ring of the scroll compressor, the cross ring blank is formed by adopting hot extrusion, so that the wear resistance and strength of the cross ring are improved, the cross ring blank formed by hot extrusion does not generate air holes, and then the percent of pass of the cross ring blank is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a scroll compressor cross ring, in particular to a manufacturing method of the scroll compressor cross ring. Background technique [0002] The scroll compressor is a compressor with a compressible volume composed of a fixed involute scroll and an involute moving scroll with eccentric orbital translation. The scroll compressor is formed by the mutual engagement of the movable and stationary scrolls with two double-function equation lines. There are many relevant documents about scroll compressors, such as scroll compressors (publication number CN1515798A). [0003] The energy efficiency ratio of the scroll compressor is already 3.4, and it can even reach 3.6-3.7. The scroll compressor has the characteristics of energy saving. With the development of society, the demand for scroll compressors continues to grow. [0004] The cross ring is the key component of the scroll compres...
