Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 5, in this embodiment, a positive side cutter mechanism is provided, including an upper die 1 and a die limiting mechanism 2, the upper die 1 includes a cam 9, a press slider 3, a nitrogen spring and a trimming cutter block, the trimming cutter block includes a positive scissor block 4 and a side scissor block 5, a driving cam guiding slider 8 is disposed on the surface of the cam 9, a driven cam guiding slider 7 is disposed on the upper die 1, and the driving cam guiding slider 8 and the driven cam guiding slider 7 are adapted.

More specifically, in this embodiment, the driver controls the upper die 1 to move downward along the surface of the cam 9, so that the positive scissors block 4 first contacts the automobile panel under the action of pressure, after the positive scissors block 4 moves downward for a certain distance, the side scissors block 5 starts to move, the positive scissors block 4 moves to a designated position, after the positive side trimming of the panel is completed, the side scissors block 5 continues to move until the stroke is completed, the side trimming is completed, after the positive scissors block 4 and the side scissors block 5 complete trimming of the panel, the side scissors block 5 exits the trimming area along the original direction, then the panel can be normally taken out and put, and by performing multiple shears on the upper die 1 in a limited procedure, the number of die procedures is saved, the operation is convenient and simple, the time is saved, and the die cost is saved.
