Problems solved by technology

[0002] Steel plate gasket flanging parts are generally formed in stages by blanking, punching, and flanging in a set of molds. This kind of process has high productivity, high forming precision of parts, complex mold manufacturing, and low mold life.
And for parts with lower flange height, the mold life is lower

Abstract

The invention belongs to the technical field of moulds and provides a composite mould for machining parts such as short flanged washers. The composite mould mainly comprises an upper mould plate (14), a lower mould plate (5), guide pillars (25), guide sleeves (24), a punch-matrix (12), a blanking die (8), a drawing cut-off punch (7), an unloading mechanism, an ejecting mechanism and a beating mechanism. The upper mould plate (14) is connected with the lower mould plate (5) through the guide pillars (25) and the guide sleeves (24), the punch-matrix (12) is connected to the lower end face of the upper mould plate (14) and is a structure with the center of the lower end face protruding downwards, a punching groove (28) and a drawing groove (29) are respectively arranged on the inner wall surface of the lower end of the through hole of the punch-matrix (12) from top to bottom, and the blanking die (8) and the drawing cutoff punch (7) are arranged on the upper end face of the lower mould plate (5). The composite mould has the advantages that mould structures are simplified, assembling difficulty and manufacturing cost of moulds are reduced, and service lives of moulds are prolonged.

Description

technical field [0001] The invention belongs to the technical field of moulds, and mainly relates to a composite mold for processing short and small flanging gasket parts, which is suitable for forming steel plate gaskets with short flanging height. technical background [0002] Steel plate gasket flanging parts are generally formed by blanking, punching, and flanging in a set of molds in stages. This kind of process has high productivity, high forming precision of parts, complex mold manufacturing, and low mold life. For parts with lower flanging heights, the mold life is lower. Contents of the invention [0003] The object of the present invention is to propose a composite mold for processing short and small flanging gasket parts, so that it can simplify the mold structure, reduce the assembly difficulty and manufacturing cost of the mold, and improve the service life of the mold. [0004] The present invention adopts following technical scheme for accomplishing above-m...
