A stamping die for automobile sheet metal parts

Abstract

The invention discloses an automobile sheet metal part punching die. The automobile sheet metal part punching die comprises a lower die seat, guide column guide sleeves, an upper die seat, a load bearing table, a shock table, a concave die and a convex die; the upper die seat and the lower die seat are movably connected through the guide column guide sleeves; the load bearing table is installed onthe lower die seat, and the shock table is installed on the upper die seat; the concave die is installed in the load bearing table in an up-down moving mode, and a concave die supporting mechanism capable of dynamically supporting the concave die is arranged in the position, corresponding to the concave die, of the lower die seat; a concave die retraction mechanism for driving the concave die toretract is arranged between the load bearing table and the concave die; the convex die is installed in the shock table in an up-down moving mode, a convex die supporting mechanism capable of dynamically supporting the convex die is arranged in the position, corresponding to the convex die, of the upper die seat, and a convex die retraction mechanism for driving the convex die to retract is arranged between the shock table and the convex die; and the load bearing table and the shock table are provided with a linkage mechanism used for controlling the concave die supporting mechanism and the convex die supporting mechanism for linkage. The automobile sheet metal part punching die is suitable for production of automobile sheet metal parts.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a stamping die for automobile sheet metal parts. Background technique [0002] Punching machine, also known as press, is a device for pressure processing materials. Its working principle is generally to drive the opening and closing of the punch and die under the action of stamping power, and then cut and punch the original parts in the mold. Hole, drawing and other processes to form stamping parts. Stamping dies are mainly used in cold stamping processing. It is a pressure processing method that uses a die installed on a press to apply pressure to the original at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] At present, with the continuous development and progress of industrial production, in order to improve the quality of industrial products, stamping die production has also been widely used. Among them, in the automobile manufa...

Problems solved by technology

And because the sheet metal part will produce strong tension when it is deformed, there will be a large friction force between the sheet metal part and the inner wall of the groove in the mold. Damage, affecting accuracy, and also affecting the handling of sheet metal parts after stamping
