Differential spirally-wound type mirror surface polishing process and polishing equipment for metal zipper

Abstract

The invention discloses a differential spirally-wound type mirror surface polishing process for a metal zipper, relating to the technical field of zippers. The zipper tooth surface of the metal zipper and a flexible abrasive band form surface contact; the zipper and the flexible abrasive band advance at uniform speed or variable speed and form a smoothly-advanced speed difference; a coarse surface layer of the zipper is cut and removed by the flexible abrasive band; the surface finish, the planeness and the dimensional tolerance of the zipper can be realized after plane polishing points with different thicknesses and polishing allowances are formed at various specific positions; and when Ra is less than 0.8, the surface of the zipper starts to show centralized light reflection similar to the mirror surface, and the centralized light reflection is vividly compared with the diffuse reflection of the traditional polishing process, so that remarkable qualities of high precision in size and high finish in the appearance of the metal zipper are improved.

Description

technical field [0001] The invention relates to the technical field of zippers, in particular to a technique for mirror-finishing, grinding and polishing the surface of a metal zipper by utilizing the principle of differential speed winding, and provides special equipment for completing the process. Background technique [0002] At present, domestic zippers are polished using wire wheel polishing technology. The wire wheel rotates at high speed to drive the wire wheel polishing brush to contact with the zipper points to achieve grinding. There are many problems in it. [0003] 1. Wire wheel polishing technology, the polishing principle is to brush and deburr the surface of the zipper, because it does not work by removing materials, so it is impossible to achieve a complete smooth surface of the zipper surface. Although the burrs on the surface of the zipper after polishing are reduced, However, its surface finish is still very rough, and it is impossible to remove the pull ...

AI Technical Summary

Problems solved by technology

[0012] In order to overcome the above-mentioned shortcomings, the present invention provides a differential-speed tape-winding metal zipper mirror polishing process, which can be used to perform mirror polishing in one-time molding of metal zippers such as copper, aluminum, and stainless steel, so that the metal zipper Obtain high-precision, high-gloss surface quality, and solve industrial problems such as insignificant polishing effect, low efficiency, and high damage rate of traditional metal zipper polishing processes
