Description

Stamping die device capable of quickly replacing punch Technical Field The utility model relates to the technical field of stamping dies, in particular to a stamping die device capable of rapidly replacing a punch. Background A stamping die is a special technological device for processing a material (metal or nonmetal) into a part (or a semi-finished product) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a material is pressed at room temperature by a die attached to a press to be separated or plastically deformed, thereby obtaining a desired part. Stamping die can change the drift according to actual demand in the operation process, but current punch's connected mode is comparatively complicated, generally all is that the workman screws up the drift through specialized tool, and the change process is comparatively loaded down with trivial details, for people brings certain trouble, is unfavorable for people to the quick replacement of drift, and whole device can't dismantle fast, for later stage people to its maintenance and change bring trouble. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides the stamping die device capable of quickly replacing the punch, which is provided for bringing convenience for the disassembly and replacement of the punch body by later people while realizing the quick installation of the punch body by enabling a plurality of connecting strips to extend into a plurality of connecting grooves on the outer wall of the punch body. In order to achieve the above purpose, the present utility model adopts the following technical scheme: But stamping die device of quick replacement drift, the on-line screen storage device comprises a base, the base upper end is equipped with the bracing piece that a plurality of symmetries set up, and is a plurality of the bracing piece upper end is equipped with the roof jointly, run through on the roof and be equipped with the pneumatic cylinder, threaded zone has been seted up to the flexible end outer wall of pneumatic cylinder, threaded zone internal thread connection has the adapter sleeve, the adapter sleeve below is equipped with the drift body, the adapter sleeve lower extreme is equipped with the connecting pipe, be equipped with the coupling mechanism that is used for connecting the drift body in the connecting pipe, the connecting pipe outer wall is equipped with and is used for carrying out driven actuating mechanism to coupling mechanism. Preferably, the connecting mechanism comprises a plurality of circumferentially arranged placing grooves formed in the inner wall of the connecting pipe, a plurality of connecting strips are arranged in the placing grooves, and a plurality of circumferentially arranged connecting grooves matched with the connecting strips are formed in the outer wall of the punch body. Preferably, the driving mechanism comprises two through rods which are symmetrically arranged on the outer walls of the placing grooves and the connecting pipes in a penetrating and sliding mode, one ends of the two through rods, which are located in the placing grooves, are connected with the connecting strips, and fixing plates are arranged at the tail ends of the other ends of the two through rods.
