Description

Technical Field

[0001] The utility model belongs to the technical field of production of drawn parts, in particular to a common mold for small drawn parts. Background Art

[0002] The production of drawn parts is mainly done by stamping and stretching through stamping dies. Stamping and stretching is a common metal forming process that applies force to metal materials to cause them to undergo plastic deformation, thereby obtaining the desired shape and size. Stamping and stretching are widely used in the automotive, electronics, home appliances and other industries.

[0003] The patent application with reference publication number CN206455069U discloses a stamping die with a common mold stretching structure, including an upper common mold and a lower common mold. The structure of the upper common mold is an upper support plate, an upper pad and an upper mold base from top to bottom, and the upper support plate, the upper pad and the upper mold base are fixedly connected; the lower common mold is provided with a lower pad and a lower support plate, the lower pad is installed on the lower support plate, and the lower pad is fixedly connected to the lower support plate. It also includes a replaceable stretching structure, which includes an upper template, a lower template and a lower stripping plate, the upper end face of the upper template is fixedly connected to the lower end face of the upper mold base, the lower end face of the lower stripping plate is fixedly connected to the upper end face of the lower pad, and the lower template is installed on the lower stripping plate. The stretching structure in the utility model can be replaced according to product needs, the upper support plate, the upper pad and the upper mold base are fixedly connected by screws, the lower pad and the lower support plate are fixedly connected by screws, and the upper template, the lower template and the lower support plate are fixedly connected by screws. The existing production process of drawn parts more or less requires one or more drawn structures to be stamped.

[0004] The patent application with the publication number CN209664126U discloses a punch head that is easy to replace, including an upper die, a pressing plate fixedly connected to the bottom of the upper die, a lower die arranged at the bottom of the upper die, a model plate fixedly connected to the top of the lower die for use with the pressing plate, a buffer mechanism fixedly connected to the four corners of the bottom of the upper die, the bottom of the buffer mechanism fixedly connected to the top of the lower die, a punch head body fixedly connected to the bottom of the pressing plate, a pressing groove for use with the punch head body provided at the top of the model plate, and a mounting block fixedly connected to the top of the punch head body. The utility model solves the problem that the existing punching die is not easy to replace the punch head and has potential safety hazards in use by setting the upper die, the lower die, the model plate, the pressing plate, the buffer mechanism, the through port, the torsion block, the punch head body, the pressing groove, the movable rod, the mounting block, the limit groove, the limit block, the slide rod, the sliding sleeve and the first spring for use. However, when the above-mentioned device is actually used, the punch head is fixed by a spring and a limit block. During the punching process of the punch head, the punch head is prone to shaking and unstable fixation, which affects the use of the device. When the punch head is punching, the reaction force will act on the limit block through the limit block, which will impact the limit block and the movable rod. Long-term use will affect the fixation of the punch head.

[0005] In view of this, the present utility model is proposed. Utility Model Content
