Linear Compressor Magnetic Barrel Processing Method

Abstract

The invention provides a method for processing the magnetic barrel of a linear compressor. Between the upper end surface of the permanent magnet and the lower end surface of the end cover of the magnetic barrel, the outer surface of the inner layer prepreg is inserted into the middle to fill the reinforcing sleeve, and the permanent magnet end The outer surface of the positioning sleeve, the outer surface of the permanent magnet, the outer surface of the middle filling reinforcement sleeve and the outer surface of the lower end of the magnetic barrel end cover are wound with the outer layer prepreg. The magnetic barrel processed by this method has low material cost and low processing cost. , Good consistency and stable quality after high temperature curing. The process method is very suitable for the manufacture of the magnetic barrel of the linear compressor, and can be widely used in the field of processing the magnetic barrel of the linear compressor.

Description

technical field [0001] The invention relates to a method for manufacturing compressor parts, in particular to a method for processing a magnetic barrel of a linear compressor. Background technique [0002] The announcement number of the authorized announcement on May 8, 2018 is CN10633518B, and the invention name is a patent for the method of making a linear compressor magnetic barrel with prepreg materials. The method of fixing the permanent magnet pieces and forming the overall structure is all through winding prepreg materials. The method is completed, especially in the gap between the permanent magnet and the upper cover, a large amount of prepreg needs to be wound to fill this part of the space. [0003] The above existing process operation wastes a lot of prepreg material, which increases the material cost of the magnetic barrel. At the same time, because the thickness of the prepreg material itself is thin, it needs to be wound for a long time by winding equipment to ...

AI Technical Summary

Problems solved by technology

[0004] The present invention wastes a large amount of prepreg materials for the above existing process operations, which increases the material cost of the magnetic barrel. Filling this part of the space increases the manufacturing cost; at the same time, due to the large number of layers of prepreg wound in this space, the thickness of the prepreg wound into this space is thicker, which is different from the outer circumference of the permanent magnet and the permanent magnet. Compared with the thickness of the prepreg wound around the circumference, there is a big difference in thickness, so when it is cured at high temperature, due to the uneven thickness of the wound prepreg, the problem of uneven stress distribution will occur during curing, and sometimes deformation will occur, which directly affects The quality of the final magnetic barrel, the technical problems of poor consistency and uniformity after the magnetic barrel is cured, provide a linear compressor with low cost of magnetic barrel materials, low processing costs, good consistency after high temperature curing, and stable quality Magnetic bucket processing method
