Problems solved by technology

Due to the problem of difficulty in picking out the side flanging, the mold must be designed with a return mechanism. Therefore, the side flanging molds all have a floating structure, which makes the structure of the mold complex, bulky, and inflexible in movement. At the same time, the cost of the mold is also high.

Abstract

The invention discloses a stamping die of a side flanging of an automobile cover. The stamping die comprises an upper die base, a lower die base, a presser arranged on the upper die base, a wedge slide block and a flanging cutter block. A wedge installing seat provided with an arc groove at the upper middle part is arranged on the middle right part of the lower die base; the right upper part of the wedge installing seat is provided with a first wedge fixed seat, and the left upper part thereof is provided with a second wedge fixed seat; a groove at the upper part of a rotary wedge corresponds to the lower part of the wedge slide block, and the right part, the left part and the lower part of the rotary wedge respectively correspond to / contact with the left part of the first wedge fixed seat, the right part of the second wedge fixed seat and the upper middle part of the wedge installing seat; and one guide plate is arranged on the right side wall of the groove at the upper part of the rotary wedge, and the left side corresponds to / is in contact with the right side of the lower part of the wedge slide block. The stamping die of the side flanging of the automobile cover has the advantages of compact structure, convenient installation, small size, flexible and stable action and low manufacturing cost.

Description

technical field [0001] The invention relates to a mold for an automobile cover part, in particular to a stamping die for a side flanging of an automobile cover part. Background technique [0002] Automobile panel flanging refers to a stamping process that turns the edge of the hole and the outer edge of the part into a vertical wall under the action of the mold. Due to the problem of difficulty in picking out the side flanging, the mold must be designed with a return mechanism. Therefore, the side flanging molds all have a floating structure, which makes the structure of the mold complex, bulky, and inflexible in movement. At the same time, the cost of the mold is also high. . Therefore, the existing side flanging stamping dies for automobile panels need to be improved in terms of structure and working principle. Contents of the invention [0003] The object of the present invention is to provide a stamping die for the side flanging of automobile panels, which has the ad...
