Description

Hydraulic arm damping mold changing frame Technical Field The utility model relates to the technical field of dies, in particular to a hydraulic arm damping die changing frame. Background The existing punching type section is mostly processed by adopting a mode of matching a female die and a male die, for example, a Chinese patent application (issued by the patent number CN219027772U name: a die carrier) comprises an upper die holder, an upper pressing plate and a lower die holder, wherein the upper pressing plate is connected to the bottom of the upper die holder, the lower end face of the upper pressing plate is used for installing an etching die, the lower die holder is correspondingly arranged below the upper die holder and is used for bearing materials, a boss is arranged on the lower end face of the upper pressing plate or the upper end face of the lower die holder, and the thickness of the boss is larger than that of the etching die, so that when the dies are matched, an uncut height is reserved between the etching die and the lower die holder, and the uncut height is equal to the thickness difference of the boss and the etching film. The die carrier can ensure that materials are not cut excessively and the service life of an etching die can be prolonged, but when the upper die is replaced on a press, the upper die and the lower die are clamped and pushed out of equipment, and then the whole upper die structure is required to be put into a material turning frame and turned over to perform die replacement operation. Disclosure of utility model The utility model aims to provide a hydraulic arm damping mold changing frame so as to overcome the defects of the prior art. The hydraulic arm shock absorption die changing frame comprises a supporting frame, wherein a large bearing piece is arranged on the supporting frame and consists of a frame body connected with the supporting frame and a boss with a closed head and tail, the boss is integrally formed at the bottom of the frame body, an inner ring of the frame body is arranged on the outer side of the inner ring of the boss in a surrounding mode, a small bearing piece is placed on the boss, the structure of the small bearing piece is identical to that of the large bearing piece, and the small bearing piece is coplanar with the two frame bodies of the large bearing piece.
