Punching device with automatic waste collecting function for tapered roller production

The utility model relates to the technical field of stamping devices, in particular to a stamping device with an automatic waste collecting function for tapered roller production, which comprises a frame, and the top surface of the inner wall of the frame is fixedly connected with an air cylinder. According to the punching device, the punching block and the toothed plates are driven by the air cylinder to move downwards, then a workpiece is punched and formed through the punching block, after punching is completed, the toothed plates and the punching block are promoted to reset through the air cylinder, and then the two toothed plates drive the two gear nuts to rotate and promote the two screw rods to move synchronously. Meanwhile, two screws are promoted to drive two mold blocks to be separated, so that an operator can conveniently take out a model, C-shaped blocks are driven to move towards the two sides through the mold blocks, meanwhile, hinge rods are promoted to be unfolded, meanwhile, waste on the bott
