Manufacturing equipment for cold extruding of gears

Abstract

The invention discloses manufacturing equipment for cold extruding of gears. The manufacturing equipment comprises a rack, and further comprises a rotating shaft, a cantilever, a connecting rod, an upper fixing seat, a sleeve, a polishing plate, a connecting ball and a lower fixing seat which are sequentially arranged along the rack, wherein the connecting ball is used for fixing the polishing plate. The rotating shaft is in rotatable connection with the rack; the cantilever is fixed with the rotating shaft; one end of the connecting rod is fixed with the cantilever, and the other end of the connecting rod is aligned with the sphere center of the connecting ball and is fixed with the connecting ball; the polishing plate and the connecting ball are fixed; and the polishing plate is in linear contact with the conical inner wall of the upper fixing seat, the conical inner wall of the lower fixing seat and the inner wall of the sleeve. The opposite sides of the upper fixing seat and the lower fixing seat are arranged to be conical, and connecting holes used for being hinged to the connecting ball are formed in the vertexes of the upper fixing seat and the lower fixing seat. The upper end of the sleeve is in static sealing with the upper fixing seat, and the lower end of the sleeve is in static sealing with the lower fixing seat. The manufacturing equipment for cold extruding of gears can improve the polishing effect of sector gear blanks.

Description

technical field [0001] The invention relates to the technical field of gear cold pressing, in particular to a gear cold extrusion device. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. Gear cold extrusion refers to the extrusion of gear blanks below the recovery temperature, also known as impact extrusion. Before the cold extrusion of the gear, the end surface of the gear blank needs to be ground to facilitate the rapid forming of the gear blank during cold extrusion. [0003] In the prior art, the grinding of the end face of the gear blank is mostly done by the worker clamping the blank with a vise, etc., and then grinding the gear blank with a grinding tool. When grinding the end face of the blank, it is often difficult, not only the grinding effect is poor but also the efficiency is low. Contents of the invention [0004] The invention intends to provide a gear cold extrusion man...
