The utility model discloses a buffering punch forming structure, which relates to the technical field of punching processing, is matched with a punch press for use and comprises a fixing plate, the fixing plate is arranged on the punch press, a plurality of connecting components are arranged between the fixing plate and the punch press, a sliding groove penetrates through the fixing plate, a forming table is arranged in the sliding groove in a sliding manner, and a pressing piece is arranged above the forming table. The buffering piece is coaxially arranged at the bottom of the forming table. According to the stamping forming structure capable of buffering, effective absorption and dispersion of impact force can be achieved through the buffering piece, the forming precision is improved, the service life of equipment is prolonged, the maintenance cost is reduced, and the quality of stamping pieces is ensured.

The application discloses a bidirectional damping adjustable hydraulic damping cylinder with self-resetting function, which comprises a cylinder barrel, a gas cavity and an oil cavity arranged in the cylinder barrel, an adjusting mechanism arranged on the cylinder barrel and used for adjusting the damping cylinder, self-resetting and bidirectional locking or unidirectional locking, a pressure storage mechanism arranged on the cylinder barrel and used for storing gas pressure in the gas cavity of the cylinder barrel, and a guiding mechanism arranged on the cylinder barrel, wherein the damping cylinder is formed by integrating various valves and a piston type pressure accumulator to realize the bidirectional damping adjustable requirement of the damping cylinder and has the self-resetting function, and the damping cylinder can be locked at an arbitrary position in a unidirectional mode or an arbitrary position in a bidirectional mode to present unidirectional or bidirectional rigid characteristics, the self-resetting function of the cylinder is realized through the area ratio relationship of the two cavities, the applicability is wider, and the application space is larger.
