Description

Technical Field

[0001] The utility model relates to the field of stamping part processing, in particular to a detachable stamping part. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping) of the desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Stamping is mainly formed by stamping metal or non-metallic sheets through stamping dies with the help of the pressure of a press.

[0003] The existing patent (publication number: CN207539126U) discloses that "it includes a lower mold, an upper left mold and an upper right mold; the left stamping punch and the right stamping punch form a connecting cavity with the embedded groove, and a hinge shaft is arranged on the stamping part, and the hinge shaft corresponds to the connecting cavity; the stamping part is placed on the stamping groove, and the hinge shaft is stamped and formed by the left stamping punch and the right stamping punch, and the embedded grooves are distributed on two parallel horizontal lines. On the same horizontal plane, the position of the left stamping punch is arranged in front of the position of the right stamping punch; the stamping part after forming is a detachable structure, and a group of detachable stamping parts can be stamped at one time, with high work efficiency; before the stamping starts, the pneumatic pressing plate is pressed down by a hydraulic press to drive the upper left mold and the upper right mold to fit with the lower mold. After the stamping is completed, the pneumatic groove is inflated by an air pump, and the stamping ejector column is ejected by pneumatic pressure, thereby separating the upper left mold and the upper right mold from the lower mold and taking out the stamping part". The inventor discovered the following problems in the prior art during the process of realizing the utility model: 1. The above device punches the stamping parts by engaging the upper left mold and the upper right mold with the lower mold. After the stamping is completed, the upper left mold and the upper right mold are separated, and the stamping parts remain in the stamping groove of the lower mold. The stamping parts fit the stamping groove, which reduces the efficiency of taking out the stamping parts. 2. When taking out the stamping parts in the device, they need to be taken out manually. The next stamping can only be carried out after the stamping parts are taken out of the device. The stamping efficiency is greatly affected by the speed of taking out.
