Abstract

The invention discloses a bending die of a double metal bracket stamping part, which comprises a lower mold plate and is characterized in that: a boss is formed on one side of the upper surface of the lower mold plate; the inner side of the boss is a slope surface; a punch head is arranged above the lower mold plate; and one side of the lower surface of the punch head is provided with a slope surface which is matched with the boss of the lower mold plate. The bending die of the double metal bracket stamping part has the advantages that: the structure is simple, and the bend stamping part has light weight, high rigidity, high strength, relatively high surface quality and a smooth and attractive appearance; and dimension precision is relatively high, and the identical modules have a uniform and homogeneous dimension and relatively high exchangeability, and the general assembling and can meet the general assembling and using requirements without further machining.

Description

technical field [0001] The invention relates to the field of stamping dies for stamping parts, in particular to a bending die for stamping parts of bimetallic brackets. Background technique [0002] Applying external force to plates, strips, pipes, profiles, etc. through punching machines and molds to cause plastic deformation or separation, so as to obtain workpieces of required shape and size. The workpieces obtained are stamping parts. [0003] Stamping parts are formed by applying external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Stamping and forging belong to plastic processing (or pressure processing) and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. [0004] Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, ligh...
