Abstract
The utility model discloses a stamping mould with a spiral-shaped concave groove at the upper end. The stamping mould with the spiral-shaped concave groove at the upper end comprises a punch and a lower mould, wherein the punch is located above the lower mould. A spiral-shaped concave groove is arranged on a side wall at an upper end of the punch. A lower end of the punch is a square punching block. The lower mould is provided with a square cavity. The stamping mould with the spiral-shaped concave groove is more reasonable in structure. And the spiral-shaped concave groove is increased at the upper end and connections between the punch and a hydraulic pressure mechanism are convenient to connect.
Description
Technical field
The utility model relates to mould.
Background technology
Mould--in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold mould (being commonly called as cold-punching mould).Punching press--be at room temperature, utilize the mould that is installed on the forcing press that material is exerted pressure, it is produced separate or plastic deformation, thereby obtain a kind of pressure processing method of required part.
The utility model content
The purpose of this utility model provides the diel that a kind of upper end has spiral groove, and structure is more reasonable, and the upper end has increased helical groove, is convenient to being connected between drift and the hydraulic mechanism.
The technical solution of the utility model is as follows:
A kind of upper end has the diel of spiral groove, includes drift, counterdie: drift is positioned at the top of counterdie, has spiral groove on the sidewall of described drift upper end, and the lower end of drift is the square piece that rushes, and described counterdie is provided with square die cavity.
