Abstract
The utility model discloses a combined stamping punch for a die for metal mechanical machining. The combined stamping punch comprises a punching part and a molding part which are combined integrally through a connecting part; the diameter of the punching part is less than the diameter of the molding part; the connecting part is of a conical-shaped structure for being connected with the punching part and the molding part, and forms a conical angle of 60-80 degrees. The combined stamping punch has the beneficial effects that through the effect of the connecting part, metal elements are hemmed further after punching, and are finally subjected to punch molding, and a working procedure is saved.
Description
Technical field
The utility model relates to the used drift of a kind of diel.
Background technology
Existing machined need to adopt for two steps carried out to punching and the crimping moulding of metalwork, and not only operation is many, and increased cost.
Summary of the invention
The utility model provides a kind of combination punching press drift, can realize simultaneously punching and crimping moulding.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of combination punching press drift is characterized in that: comprise punching section and forming part, and be combined into one by connecting portion, described punching section diameter is less than the forming part diameter.
The above connecting portion is for connecting the cone structure of punching section and forming part, and the formed cone angle of described connecting portion is 60-80 °.
The beneficial effects of the utility model are, by the effect of connecting portion, make behind the metal workpiece punching further crimping, and a procedure has been saved in final punch forming.
Description of drawings
Fig. 1 is the utility model product shelves holder structure schematic diagram.
Among the figure: 1. punching section; 2. connecting portion; 3. forming part.
The specific embodiment
By accompanying drawing 1 as can be known, the utility model comprises punching section 1 and forming part 2, and is combined into one by connecting portion 2, and described punching section 1 diameter is less than forming part 3 diameters.Described connecting portion 2 is for connecting the cone structure of punching section 1 and forming part 3, and described connecting portion 2 formed cone angles are 60-80 °.
Metalwork is after 1 punching of punching section, because the effect of connecting portion 2 is carried out crimping with the hole that rushes, at last again through punch forming.
Should be noted that embodiment described in the utility model only is its optimal way, only is apparent change to belonging to technical solutions of the utility model, all should belong within the protection domain of the present utility model.
Claims (2)
