Abstract
The invention provides a device for punching a left instrument panel middle beam support. The device comprises an upper die plate and a lower die plate. The two ends of the rear portion of the lower die plate in the length direction are both fixedly provided with a guide column. A mandrel fixing plate is arranged between the two guide columns. The support is fixed to the position, corresponding to the front of the mandrel fixing plate, of the front portion of the lower die plate. An elastic positioning device is disposed between the mandrel fixing plate and the support in a matched mode. A first semi-circular hole groove is formed in the mandrel fixing plate, a mandrel is fixedly arranged in the first semi-circular hole groove, three bar-shaped holes are evenly formed in the circumferential surface of the front end of the mandrel, a first semi-circular groove is formed in the elastic positioning device, and a second semi-circular groove is formed in the support. The upper die plate is movably arranged on the guide columns, a die handle is installed in the middle of the upper surface of the upper die plate in a threaded connection mode, and multiple reinforcing ribs are disposed on the die handle. The device has the advantages of being simple in structure, low in cost and easy to use and popularize.
