Buffering mechanism of press machine

The utility model provides a press machine buffering mechanism which comprises a platform, a base, supports, a punching machine, a pressing plate frame, a buffering groove, a pressing plate, pressing plate supports, a buffering plate, a horizontal cross rod, a spring and a limiting rod, and in the press machine buffering mechanism, due to the arrangement of the buffering groove, when the punching machine makes contact with the upper end of the pressing plate, the pressing plate supports on the two sides of the pressing plate are used for supporting; the buffering plate buffers the pressing plate support through the buffering plate under the action of the spring, at the moment, the pressing plate is buffered, pollution noise is avoided, meanwhile, vibration during punching is reduced, the service life of the punching machine is prolonged, and the buffering mechanism can be widely applied. Through the arrangement of the horizontal cross rod, the balance of the buffer plate is guaranteed during buffering, the pu
