[0002] When automobiles are produced, it is necessary to punch holes in sheet metal. For example, the utility model patent with the announcement number CN212238841U discloses a steel plate punching device for automobiles. The first servo motor drives a pusher to move, and the pusher pushes out the steel plate at the bottom of the plate storage bucket. The punching head is then driven by a cylinder to punch holes in the steel plate, and finally the steel plate is transported outward.

[0003] However, when the utility model is in use, since the space in the plate storage bucket cannot be adjusted, when the area of ​​the plate material differs greatly from the area of ​​the plate storage bucket, the side wall of the plate material cannot be effectively limited and is prone to tilting, which affects the effect of feeding and does not have good applicability. In addition, the size of the discharge port of the plate storage bucket is fixed. If the thickness of the plate material is greater than the height of the outlet, it cannot be used. Therefore, a plate punching device for automobiles needs to be developed urgently. Utility Model Content
