Polishing device for cotter pin machining

Abstract

The invention provides a polishing device for cotter pin machining. The polishing device comprises a supporting base, wherein a pay-off reel and a take-up reel are arranged on the supporting base; twopolishing mechanisms are arranged on the upper side of the supporting base; each polishing mechanism comprises supporting plates arranged on the two sides of a metal wire correspondingly; a first polishing roller and a second polishing roller are arranged between the two supporting plates; a vertically-arranged through groove is formed in each supporting plate; a sliding block is arranged in eachthrough groove; a rotating shaft of each first polishing roller is rotationally installed on the corresponding sliding block; installing grooves parallel to the through grooves are formed in the twosides of each through groove; installing plates on the two sides of each sliding block are installed in the corresponding installing grooves through bolts; a horizontal plate is arranged on the tops of the supporting plates; a limiting roller is arranged between the horizontal plate and the supporting base; a guide rail is arranged at the bottom of the horizontal plate; a reciprocating lead screwis arranged in the guide rail and sleeved with a nut; the lower side of the nut is connected with a polishing block through a connecting rod; a support is arranged between the polishing block and theconnecting rod; and a spring is arranged between the support and the polishing block. By means of the device, continuous polishing of the metal wires can be achieved, and the polishing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of cotter pin processing equipment, in particular to a polishing device for cotter pin processing. Background technique [0002] In the process of split pin processing, the raw material needs to be drawn through a wire drawing die to draw the bar into a thinner metal wire, and then flattened by a rolling die to form a flat on one side and a circular arc on the other side. For metal wires, since the drawn wires cannot guarantee a clean and smooth surface, the subsequent processing quality will be affected. The metal wire needs to be polished to achieve a bright and clean effect, otherwise the surface stains, scratches, and lack of smoothness of the metal wire will affect the processing quality of the cotter pin. [0003] In order to make the surface of the metal wire meet the requirements, it needs to be polished. The existing polishing methods are divided into mechanical polishing and chemical polishing. Most of the ...

Problems solved by technology

[0003] In order to make the surface of the metal wire meet the requirements, it needs to be polished. The existing polishing methods are divided into mechanical polishing and chemical polishing. Insufficient problem, and the equipment is more complicated, and cannot be polished continuously; chemical polishing generally uses pickling solution for pickling, but the effect is not good
