Abstract

The invention discloses a continuous punch forming method of plates. The method is characterized by comprising the following steps of S1, feeding the plates one by one by a conveying table; S2, driving a near-arc section on a cam to make contact with two pin rollers, and feeding the plates to a position over a lower die; S3, bending and punching the plates, allowing a first transition section on the cam to gradually make contact with the two pin rollers, allowing a vertical sliding plate to gradually ascend, bending the plates along with the continuous ascending of the vertical sliding plate,allowing an upper punch to punch a bottom of a U-shaped connecting piece, meanwhile, allowing a transverse sliding plate to move leftwards, and allowing a left punch to punch a side wall of the U-shaped connecting piece; S4, conducting pressure maintaining forming; S5, unloading the U-shaped connecting piece, and S6, repeating steps S2 to S5 to achieve the automatic continuous stamping of the plates. The invention provides the continuous punch forming method of the plates, and the one-time bending and punching operations of the U-shaped connecting piece are achieved.

Description

technical field [0001] The invention relates to the stamping field, in particular to a continuous stamping forming method for plates. Background technique [0002] For most conventional sheet metal parts, due to the multiple processing procedures involved, it is generally impossible to use a pair of molds for one-time stamping and forming. The usual method is to use composite molds for continuous stamping and forming. There are three main types of conventional composite molds: (1) punching composite molds such as blanking and punching composite molds; cutting and punching composite molds, etc.; (2) forming composite molds such as bending composite molds and composite extrusion molds; (3) Blanking and forming composite molds such as blanking, deep drawing composite molds; punching, flanging composite molds; deep drawing, trimming composite molds; blanking, deep drawing, punching, flanging composite molds, etc. [0003] As for the continuous stamping method of sheet metal, th...
