Example Embodiment

[0028] Combine below Figure 4 to Figure 10 , To further explain the present invention:

[0029] Such as Figure 4 As shown, it is the first state of the rotary pressing wedge to perform pressing and wrapping, that is, the unprocessed state. The straight side of the inner panel 25 is attached to the straight side of the outer panel 24 and waits to be pre-compressed.

[0030] Such as Figure 5 As shown, it is the second state where the rotary pressing wedges implement pressing and wrapping, namely the pre-bending state. The pre-bending insert 2 pre-bends the other straight side of the outer plate 24. The angle formed by the two straight sides of the outer plate 24 is changed from large to small.

[0031] Such as Image 6 As shown, it is the third state of the rotary pressing wedge to implement the pressing and wrapping, that is, the pressing completion state. The pressing insert 10 presses the other straight side of the outer plate 24.

[0032] Such as Figure 7 with Figure 8 As s...

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...
