Description
Technical field
The utility model relates to machining equipment technical fields, and in particular to a kind of mold air blowing formed punch.
Background technique
The metal parts in stamping die in machine tool, is called and rushes stick, red needle or punching pin, be mounted in punching press
On mold carry out continuous stamping punching press thrust operation, make machined material occur separation or plastic deformation, formed punch also cry punch-pin, on
Mould, formpiston, red needle etc., formed punch are mounted in the metal parts in stamping die, contact applied to the direct of material, make material
Deformation occurs, cuts material, thus finished product required for obtaining or semi-finished product.
Be used to ventilate without a hole either tiny hole inside traditional formed punch, will during punching press waste material with
Product separates.But traditional punch structure is complicated, operation difficulty is big, it is not easy to repair, use value is low, waste material and product
Separating effect it is unobvious, and the size in hole cannot be increased according to the size of diameter, it cannot be guaranteed that enough gas product and
Waste material separates.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of mold air blowing formed punch is provided, is tied
Structure is simple, easy to operate, easy-maintaining, practical, and use value is high, can increase the size in hole according to the size of diameter, increase
One bellmouth is used to store tolerance, and guarantee has enough gas that product and waste material are separated.
To achieve the above object, the utility model is using following technical scheme: it includes upper punch 1, middle formed punch 2, ring
Groove 3, low punch 4, bellmouth 5, through-hole 6 are provided with middle formed punch 2 below the upper punch 1, are provided with ring below middle formed punch 2
Groove 3 is provided with low punch 4 below ring groove 3, and 4 lower end of low punch is provided with bellmouth 5, and through-hole 6 runs through upper punch 1, middle punching
First 2, ring groove 3, low punch 4, and through-hole 6 is connect with bellmouth 5.
The ring groove 3 is arcuate shape.The ring groove 3 of arcuate shape can be reduced since formed punch excessively rushes in hitting
First 2 effect.
The upper punch 1, middle formed punch 2, ring groove 3, low punch 4 are integrated.The upper punch 1 of integral structure,
Middle formed punch 2, ring groove 3, low punch 4 keep structure whole more stable and firm, it is not easy to cause the damage between component because of punching press
It is bad.
The upper punch 1, middle formed punch 2, low punch 4 are cylindrical shape.The upper punch 1 of cylindrical shape, middle formed punch 2, under
Formed punch 4 can reduce the friction to stamping parts in punching press, also reduce the damage of formed punch, improve the service life of formed punch.
Working principle of the utility model is: being provided with middle formed punch 2 below upper punch 1, ring groove is provided with below middle formed punch 2
3, be provided with low punch 4 below ring groove 3,4 lower end of low punch is provided with bellmouth 5, through-hole 6 through upper punch 1, middle formed punch 2,
Ring groove 3, low punch 4, and through-hole 6 is connect with bellmouth 5, through-hole 6 can be such that gas enters, and gas storage is carried out at bellmouth 5,
More convenient gas separates product and waste material.
After adopting the above technical scheme, the utility model has the beneficial effect that structure is simple, it is easy to operate, easy-maintaining, practical
Property it is strong, use value is high, can increase the size in hole according to the size of diameter, increase a bellmouth and be used to store tolerance, protects
Card has enough gas that product and waste material are separated.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the cross-sectional view of the utility model；
Fig. 2 is the main view of the utility model；
Description of symbols: upper punch 1, middle formed punch 2, ring groove 3, low punch 4, bellmouth 5, through-hole 6.
Specific embodiment
Referring to shown in Fig. 1-Fig. 2, present embodiment the technical solution adopted is that: it include upper punch 1, middle formed punch 2,
Ring groove 3, low punch 4, bellmouth 5, through-hole 6 are provided with middle formed punch 2 below the upper punch 1, are provided with below middle formed punch 2
Ring groove 3, is provided with low punch 4 below ring groove 3, and 4 lower end of low punch is provided with bellmouth 5, through-hole 6 through upper punch 1, in
Formed punch 2, ring groove 3, low punch 4, and through-hole 6 is connect with bellmouth 5.
The ring groove 3 is arcuate shape.The ring groove 3 of arcuate shape can be reduced since formed punch excessively rushes in hitting
