Steel back pressure hypotenuse fine blanking continuous die and steel back production method

Abstract

The invention discloses a steel back pressed bevel edge fine trimming continuous mold and a steel back production method. The steel back pressed bevel edge fine trimming continuous mold comprises an upper mold holder, an upper base plate, a gear ring plate base plate, a middle supporting plate, a gear ring plate, a lower mold plate, a lower base plate and a lower mold holder, wherein the upper base plate is arranged below the upper mold holder, the gear ring plate base plate is arranged below the upper base plate, the middle supporting plate is arranged below the gear ring plate base plate, the gear ring plate is embedded inside the middle supporting plate, the lower mold plate is arranged below the middle supporting plate, the lower base plate is arranged below the lower mold plate, and the lower mold holder is arranged below the lower base plate. A pressed bevel edge lower male device used for carrying out bevel edge pressing on a steel back material band is arranged on the lower mold plate. By means of the structure of the steel back pressed bevel edge fine trimming continuous mold, the bevel edge pressing process of a steel back is directly completed in the mold, the deformation defect caused by the fact that bevel edge pressing is independently carried out through an oil press is avoided, the product quality and the pass percent are improved, the process steps are reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a continuous die for steel back pressure hypotenuse fine blanking and a steel back production method. Background technique [0002] Beveling is widely used in the product structure design of steel backs for brakes. Almost 80% of steel backs require different degrees of beveling, so the beveling process has become a characteristic mark in the production of steel backs. [0003] The existing steel back pressure hypotenuse process is realized by using a single punch forming die on a hydraulic press after the blanking separation process. Due to the large degree of plastic deformation of the material, the force on one side of the mold, and the small adjustment range of the pressing force, quality problems such as excessive thickness of the product and poor flatness of the back of the deformation perimeter often occur after this process; Guaranteed to cause great distress. This is als...
