Edge covering mold structure with rotating press fit wedge

Abstract

The invention relates to an edge covering mold structure with a rotating press fit wedge. The edge covering mold structure comprises an upper mold body (1) and a lower mold body (4), a lower mold insert (3), a pre-bending wedge (5) and a press fit driving block (6) are arranged on the lower mold body (4), a pre-bending drive block (8) and the rotating press fit wedge (9) are arranged on the upper mold body (1), a pre-bending insert (2) is fixedly arranged on the pre-bending wedge (5), a press fit insert (10) is arranged on the rotating press fit wedge (9), a plate is arranged on the lower mold insert (3) and is composed of an inner plate (25) and an outer plate (24), and the edge covering mold structure is characterized in that the moving direction of the press fit insert (10) is changed through the rotating press fit wedge (9), the press fit insert (10) conducts press fit edge coverage in the normal direction of the press fit edge coverage face, and the phenomenon that in the press fit process of an existing press fit edge coverage mold structure, component force parallel to the press fit edge coverage face is generated, an appearance ridge and the outer surface of a press fit edge coverage association part are stretched, and the plate is deformed is avoided.

Description

technical field [0001] The invention relates to the technical field of cold stamping of automobile cover parts, and relates to a hemming die structure with a rotary pressing wedge. Specifically, it is especially used for the pressing and hemming process of the engine cover assembly and the luggage cover assembly. The outer surface profile of the parts related to the pressing is steep, and the hemming mold using the rotary pressing wedge The structure is used to ensure that the appearance ridge line of the workpiece and the outer surface of the associated parts of the pressing and wrapping will not be stretched and deformed during the pressing and wrapping. Background technique [0002] Stamping dies for automobile body panels are the most demanding and difficult to process dies in automobile body manufacturing. The quality of the car outer covering directly affects the appearance quality of the whole car. Take the rear door of a certain car model as an example, such as fi...

Problems solved by technology

[0004] The present invention designs a hemming mold structure with a rotary pressing wedge, which solves the technical problem that the existing pressing and hemming mold structure produces a component force parallel to the direction of the hemming surface during the pressing process. The outer surface of the appearance ridge line and the associated part of the pressing and wrapping will be stretched and the plate will be deformed
