Abstract

The invention relates to the technical field of machining devices, in particular to a punching machine. The punching machine comprises a rack. A punching head and a lower die used for punching a workpiece are arranged on the rack. The lower die is formed by splicing multiple combination blocks. The combination blocks are connected with the rack in a sliding manner. A grinding disc rotationally connected with the rack is further arranged below the lower die. A downward pressing plate is further arranged above the grinding disc, and the downward pressing plate is connected with the rack in a sliding manner. An air chamber is arranged below the grinding disc, and a piston plate is connected in the air chamber in a sliding manner. A sleeve is fixed to a piston. The sleeve is in threaded connection with a fixing rod, the air chamber communicates with two cylinder bodies, and movable plates fixed to the downward pressing plate are arranged in the cylinder bodies in a sliding manner. By meansof the punching machine, the problem that burrs on the back face of a workpiece cannot be removed through an existing punching machine is solved, and the punching quality is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a punching machine. Background technique [0002] Punching machines are often used in mechanical processing. Punching machines generally include a lower die and a stamping head driven by an oil cylinder. The lower die has a die hole, and the punching head presses and punches the workpiece placed on the lower die. However, there will be protruding burrs on the back of the holes punched out by the punching machine, which is not smooth. When installing a connecting piece in a punched hole in a workpiece, the protruding burr will affect the stability of the connecting piece. Contents of the invention [0003] The problem to be solved by the present invention is to provide a punching machine capable of removing the burrs on the back of the hole and improving the punching quality. [0004] The scheme is basically as follows: [0005] A punching machine, com...
