Clipping tool installed at the tip of the punching of the corner of the chassis to be able to firmly bond the interior and exterior materials of the chassis to each other.

In the preceding data, the movable block is moved toward the fixed block so that the inner side of the edge of the chassis can be pressurized and supported, that is, the movable block is directly connected to the operation rod of the transfer cylinder installed in front of the movable block on the lower surface of the work table. Forms have been proposed. In the preceding data, when the operating rod of the transfer cylinder is contracted when the chassis to be clipped is fixed, the movable block connected to the front end thereof moves toward the fixed block to press and support the inner side of the edge of the chassis. When the working rod of the transfer cylinder is extended, the moving block moves toward the front of the worktable and is separated from the inside of the edge of the chassis so that the chassis can be taken out.

Meanwhile, when the corner portion of the chassis supported by the fixed block and the moving block is clipped through the clipping block, the tip of the clipping tool of each clipping block moving forward obliquely is pressed into the outside of the corner of the chassis so that the chassis is pushed toward the moving block. Since the preceding data in the clipping process prevents the moving block from being pushed through the shrinkage bearing force of the transfer cylinder operating rod in the clipping process, a large load is applied to the transfer cylinder operating rod, and the chassis of the clipping block through the clipping tool When the pressing force is greater than the contraction support force of the transfer cylinder operating rod, the chassis is pushed forward, and thus the chassis support force is weakened, such that clipping is not performed properly.
