A cover mold used to cancel the phosphating process

Abstract

The invention discloses a cover plate mold for cancelling a phosphating process. The cover plate mold is mainly composed of an upper template, a compression spring, an upper baseplate, an upper mold core baseplate, fixing screws, an upper mold core, a fixing plate, an upper transmission piece pressure block, a mold frame, a limiting mechanism, a lower template, a discharging plate, a lower transmission piece pressure block, a lower mold core baseplate, a lower baseplate, a lower mold core, a locating block, a step structure mounting surface pressure block, a flanging pressure block, an upper mounting surface pressure block, a guide pillar and a guide sleeve. According to the cover plate mold, through regulation of the cover plate mold structure and a clearance, formation after phosphatingis not required; a cover plate is directly subjected to stretch forming, and destructive treatment to the surface is not required; the surface strength of the cover plate can be improved, and meanwhile the production efficiency is improved; and the production cost, labor intensity and environmental pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of clutch cover surface treatment and processing, and in particular relates to a cover plate mold for canceling the phosphating process. Background technique [0002] After the original cover plate is stamped and processed, the surface needs to be phosphated before the next step of forming. The working steps are blanking - material preparation - degreasing - pickling - surface adjustment - phosphating - saponification - unloading - forming, a total of 9 processes , high production cost, low production efficiency, high labor intensity, and pickling needs to use industrial hydrochloric acid, which will produce acid sewage, poor production environment, phosphorus content in the phosphating solution, a certain odor will be generated during the forming process, pollution environment. Contents of the invention [0003] The object of the present invention is to provide a cover plate mold for eliminating the phos...
