Automatic waste collection type precision part stamping die

Abstract

The invention belongs to the technical field of stamping dies, and particularly relates to an automatic waste collection type precision part stamping die. The automatic waste collection type precision part stamping die comprises a base, a stamping disc, stamping columns, a feeding groove and a waste recycling mechanism; the feeding groove is formed in the base, and the stamping disc is arranged above the base; the stamping columns with different diameters are fixedly mounted in the lower end wall of the stamping disc; and the lower ends of the stamping columns are arranged in the upper end wall of the base, and the waste recycling mechanism is arranged below the stamping columns. When the stamping columns make contact with the upper surface of a metal plate, a sliding column in the stamping columns make contact with the upper surface of the metal plate firstly, then the sliding column slides towards the interior of an air pressure cavity by a certain distance under the action of stamping force, the air pressure cavity communicates with the interior of a balance bag, and therefore, when the air pressure in the air pressure cavity is extruded, the air pressure in the air pressure cavity can be conveyed into the balance bag, the sliding column and the balance column can be in a balanced state in the punching process, and smooth punching is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of punching dies, in particular to a stamping die for precision parts with automatic waste collection. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] During the working process of the stamping die, it usually works intermittently, because the press will exert pressure on the material to cause it to deform or separate when it is working, which makes it necessary to manually remove the stamping waste after stamping to continue stamping operation, which wastes a lot of manpower and material resourc...

AI Technical Summary

Problems solved by technology

[0003] During the working process of the stamping die, it usually works intermittently, because the press will exert pressure on the material to cause it to deform or separate when it is working, which makes it necessary to manually remove the stamping waste after stamping to continue stamping operation, which wastes a lot of manpower and material resources. This phenomenon is more common in the operation of stamping and opening, and at the same time greatly limits the production efficiency of enterprises. Although there are machines for removing waste in the prior art, this removal Waste machinery is usually set up separately. Although waste removal can also be achieved, it takes a long time and is also not conducive to improving the production efficiency of enterprises.
