High-precision manufacturing method of switch housing

Abstract

The invention provides a switch shell and a high-precision manufacturing method thereof and solves the problems that an existing switch shell and a high-precision manufacturing method is insufficient in machining accuracy level, and products are interspersed with one another to cause deformation due to the fact that strip gaps are cut too wide after packing and the like. The switch shell comprises a flaky body which is provided with a middle strip, a bending protrusion is formed by recessing in the middle strip, and a long strip hole tool edge parallel to side of the middle strip is arranged in the side of the middle strip. The high-precision manufacturing method includes the steps of 1), punching a pre-broken line; 2), punching a positioning hole; 3), punching the long strip hole tool edge; 4), punching product outlines; 5), punching chamfers on two sides of the bending protrusion and a one-sided chamfer of the long strip hole tool edge. Through combining action of the additional part structure and the manufacturing process, product precision can be improved with dimensional stability, the problem that the products are interspersed with one another to cause deformation can be solved, the probability of unqualified products is lowered, and quality of the products is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic component processing, and relates to a switch shell product and its production method, in particular to a switch shell and its high-precision manufacturing method. Background technique [0002] With the rapid development of my country's social economy and technology, the technology of electronic products is becoming more and more technological and advanced, and people are more inclined to the demand direction of multiple functions, concentrated performance and convenient portability. Therefore, the physical development trend of electronic products is smaller and smaller, more sophisticated and integrated. Therefore, all the important electronic components inside are also developing towards the direction of thin, small and light, and require high precision at the same time. [0003] At present, there are two technical difficulties in the manufacturing technology of such products as switch housi...

AI Technical Summary

Problems solved by technology

The two sides of the bent protrusion need to be chamfered with a tolerance of +0.02mm / -0, because the existing chamfered stamping parts only make the chamfers of the two sides of the bent protrusion, and based on the part itself, the tolerance is only It is made of + / -0.02mm stainless steel, so the strength of the forming part is weak, which increases the difficulty of precise processing
