Valve oil seal progressive die

Abstract

The invention provides a valve oil seal progressive die, relates to the technical field of progressive dies. The problems that parts with extremely high size requirements cannot be produced in batchesand the production efficiency of a traditional valve oil seal progressive die is reduced due to insufficient precision of the traditional progressive die are solved. The valve oil seal progressive die comprises a base, the base is of a cuboid structure, and a small base disc is fixedly installed on the left side of the center. A large base disc comprises preformed holes, a second drawing groove,a bottom punching hole, a chamfering groove, a product discharging opening and a waste cutting groove, a row of circular hollow groove holes are vertically formed in the upper end of the middle of thelarge base disc, a pair of circular preformed holes are formed in the top end of the left side of the large base disc, the second drawing groove is formed in the middle of the pair of preformed holes, the right end of the reserved hole on the right side is connected with the bottom punching hole, the chamfering groove is formed in the right side of the bottom punching hole side by side, the product discharging opening is close to the chamfering groove, the waste cutting groove is located in the top of the rightmost side of the large base disc, and the same function is improved.

Description

technical field [0001] The invention relates to the technical field of progressive molds, and more specifically, to a valve oil seal progressive mold. Background technique [0002] During the stamping process of the progressive die, the strip of material always moves in one direction; the strip inside the mold moves to two or more directions after being cut off, which is called a progressive die; the strip feeding completed inside the mold is called an automatic continuous die. ;In a stamping production chain, stamping dies of different processes are used with manipulators or other automation facilities, and the die or parts are moved to complete the stamping processing of the workpiece. The rated die is called a multi-station die, which has high productivity and is especially used in a valve oil seal. Progressive Die. [0003] For example, the patent No. is CN204365883U. The present invention relates to a progressive mold, which includes an upper mold body and a lower mold...
