Buffering mechanism of press machine

The utility model provides a press buffering mechanism which comprises a piston cylinder, a threaded rod, a compression spring and a second compression spring, one end of the threaded rod is installed in one end of the piston cylinder in a sliding mode, and a nut is installed on the threaded rod through threads. The compression spring is arranged outside the nut in a sleeving mode and located between the piston cylinder and the nut. According to the utility model, the overall arrangement and structure are simple, later-stage maintenance is facilitated, when the whole body breaks down in the later stage, damaged parts can be independently maintained and replaced conveniently, during maintenance and replacement, the input cost can be reduced, meanwhile, the buffering stroke can be adjusted according to the requirements of the press machine, multiple buffering effects are achieved, and the service life of the press machine is prolonged. Therefore, the whole device is more convenient, flexible and safe. 本实用新型提供一种
