Method for manufacturing air condition compressor balance block

Abstract

The invention provides a method for manufacturing an air condition compressor balance block, belonging to the technical field of mechanical engineering. By means of the method, the technical problems that the production efficiency is low, the reject rate is high and the like when high manganese steel is adopted to manufacture the air condition compressor balance block in a conventional method for manufacturing the air condition compressor balance block are solved. The method for manufacturing the air condition compressor balance block comprises the following steps of: A, blanking: cutting a section made from high manganese steel materials into blanks with a length corresponding to a required length; B, pre-pressing forming: putting the blanks in a mould and extruding into process products with shapes similar to the shapes of finished products; C, softening and lubricating treatments: carrying out the softening treatment and the phosphorization and saponification lubricating treatment on the process products; D, coining forming: putting the process products subjected to softening and the lubricating treatments in the mould to carry out extrusion forming to obtain semi-finished products; and E, machining: clamping the semi-finished products on a machine tool and machining to obtain the finished products. The method provided by the invention has the advantages of low production cost, high production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a balance block of an air-conditioning compressor, in particular to a method for manufacturing the balance block of an air-conditioning compressor. Background technique [0002] With the improvement of people's living standards, more and more families are equipped with air conditioners to improve the living environment, the popularity of air conditioners is getting higher and higher, and the output is getting higher and higher. The machine is an important part of the air conditioner. [0003] Such as figure 1 As shown, most air-conditioning compressors generally use rotary piston compressors, and the piston 4 converts mechanical energy into pressure energy under the drive of the motor through the crankshaft to compress the refrigerant in the compressor cylinder 3 . The motor provides power for the operation of the compressor and is the power source of the compresso...

AI Technical Summary

Problems solved by technology

The non-magnetic alloy material can meet the technical and process requirements of the compressor balance weight, but the production cycle of the balance weight is very long if the above method is used, and the heat treatment alone takes as long as 15 to 24 hours. The production efficiency is low and it is difficult to carry out mass production.

In addition, because the balance weight is completed by casting, there are still some problems in production, such as the internal structure of the casting is thick, and there are often casting defects such as shrinkage porosity and pores, which lead to the mechanical properties of the casting not as high as the forging, and the weight deviation is large. Difficult to manufacture high quality compressor balance weights

In addition, there are many casting processes, and some processes are difficult to control accurately, which makes the quality of castings not stable enough and the scrap rate is high
