Metal zipper surface chamfering and polishing components and chamfering polishing machine

Abstract

A metal zipper surface chamfering and polishing assembly comprises chamfering cutter assemblies which are arranged symmetrically. Chamfering cutters are transversely and longitudinally arranged in a staggered mode, at least three layers of chamfering cutter sets are arranged vertically, each layer is at least horizontally provided with two chamfering cutters, the chamfering cutters on the middle layer are arranged on driving shafts, the chamfering cutters on the upper portion and on the lower portion of the middle layer are arranged on driven shafts, each driving shaft is provided with a driving friction wheel and a linkage gear, each driven shaft is provided with a driven friction wheel, the friction wheels in the chamfering cutter sets of two adjacent layers in the longitudinal direction are in contact in a compressing mode, and the linkage gears are sequentially in meshed transmission. By means of friction wheel transmission and linkage gear meshed transmission, the chamfering cutters are driven to rotate, two adjacent chamfering cutters rotate reversely, power is transmitted to the driving shafts in the chamfering cutter assemblies through a belt transmission device, and the side where the chamfering cutters are arranged is provided with guide wheels. The invention further discloses a corresponding chamfering and polishing machine. By means of the metal zipper surface chamfering and polishing assembly and the chamfering and polishing machine, metal zippers can be polished completely and are effectively protected.

Description

Technical field [0001] The invention relates to the technical field of metal zipper manufacturing equipment, in particular to a polishing device for flattening and chamfering the surface of the metal zipper. Background technique [0002] Zippers are mainly composed of microphone teeth, sliders, limit codes or locking parts. In the processing of metal zippers, the burrs formed during the molding, cutting and tooth implantation of metal zippers greatly reduce the smoothness of the zipper, especially in processing. During the process, the burrs on the surface of the zipper can easily cause the microphone to jam when engaged or disengaged. Therefore, in the processing of metal zipper, the metal zipper needs to be polished to improve the smoothness of the zipper surface and make the zipper pull Smooth. At present, metal zippers are generally polished using wire wheel polishing technology. The wire wheel rotates at a high speed to drive the wire wheel polishing brush to point contact ...

AI Technical Summary

Problems solved by technology

At present, wire wheel polishing technology is generally used to polish metal zippers. The wire wheel rotates at a high speed to drive the wire wheel polishing brush to contact with the zipper point to achieve grinding. Wire wheel polishing is to use a wire wheel to brush and deburr the surface of the zipper. , because the steel wire of the wire wheel cannot be made extremely thin, it is impossible to achieve a completely smooth surface of the zipper, and it is impossible to remove the pull marks left after the zipper is punched out, resulting in the original remaining margin of the zipper cannot be removed; on the other hand, The existing metal zipper polishing assembly usually uses a separate belt or gear transmission structure to drive the polishing wheel installed and fixed on the main vertical plate of the polishing assembly to rotate at high speed to polish the surface of the metal zipper. Since the zipper itself is a small thing, The teeth are soft, so it is not suitable to use too much force for grinding and polishing, otherwise the surface of the teeth will be damaged to varying degrees
