The utility model discloses profitable effect is, adopts polygonal head needle type, can improve screw head's precision.
Description
Technical field
This utility model relates to screw forming punching head technical field, is specifically related to the high-accuracy screw precise forming drift of mobile phone.
Background technology
Mobile phone is exactly that the screw head to mobile phone is punched out with high-accuracy screw precise forming drift, it is simple to the installation of screw.Materials processing, in Cold Press Working, is become part by diel.Punching press--it is at room temperature, utilizes the mould being arranged on forcing press that material is applied pressure so that it is to produce and separate or plastic deformation, thus obtain a kind of pressure processing method of required part., make material occur to separate or plastic deformation after the die assembly being arranged on forcing press dieparts such as red needle directly and material, thus the part needed for obtaining.Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with the precision quality etc. of Design of Dies and dieparts.Screw head the most on the market is mostly cross, and cross head is easily deformed, and precision is the highest, in order to meet the demand of high accuracy screw, needs to produce to be unlikely to deform screw head structure.
Utility model content
In order to solve deficiency of the prior art, this utility model provides the high-accuracy screw precise forming drift of high-precision mobile phone.
The technical solution of the utility model is as follows:
Described mobile phone is with high-accuracy screw precise forming drift, the pole including mould tailstock, being arranged on mould tailstock and the head needle-like being arranged on plane on pole, the upper surface of described head needle-like is crowning, and convex apexes is formed on the top of crowning, described crowning forms protruding angle at convex apexes, described pole forms position limiting structure with head needle-like at pole upper surface, and described head needle-like is column structure.
Described mobile phone is with high-accuracy screw precise forming drift, it is characterised in that described head needle-like cross section is quincunx, and described quincuncial six edges and summit all use arc-shaped transition.
Described mobile phone is with high-accuracy screw precise forming drift, it is characterised in that described mould tailstock, pole and head needle-like use one-body molded.
Described mobile phone is with high-accuracy screw precise forming drift, it is characterised in that described head needle-like is arranged on the center of pole.
Described mobile phone is with high-accuracy screw precise forming drift, it is characterised in that described protruding angle is 120 °-125 °.
Described mobile phone is with high-accuracy screw precise forming drift, it is characterised in that described head needle-like sectional dimension is less than the size of the upper surface of pole.
This utility model has the advantages that, uses polygonal head needle-like, it is possible to increase the precision of screw head.Use arc-shaped transition to be prevented from producing stress to concentrate, improve the life-span of head needle-like.In head needle-like, plane uses crowning and forms the quality of the convex apexes high punching press of energy on crowning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is the A-A face profile of this utility model Fig. 2；
In figure: 1, mould tailstock, 2, pole, 3, head needle-like.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further elaborated.
As Figure 1-3, mobile phone is with high-accuracy screw precise forming drift, including mould tailstock 1, pole 2 and head needle-like 3, described pole 2 is arranged on mould tailstock 1 on the center of plane, described head needle-like 3 is arranged on pole 2 on the center of plane, described head needle-like 3 section triangle, tetragon or polygonized structure, and the upper surface of described head needle-like 3 is crowning, described crowning forms convex apexes at apex, and the angle at described convex apexes is 120 °-125 °.Use convex apexes can increase pressure in punching press contact position; head needle-like 3 is preferably poured; and the size of angle arranges and head needle-like 3 can be protected to be hardly damaged; the sectional dimension of described head needle-like 3 is less than the upper planar dimension of pole 2; upper plane at pole 2 forms position limiting structure, it is possible to carry out spacing to the hole depth of punching press.Described mould tailstock 1, pole 2 and head needle-like 3 are formed in one.Work process, under the effect of the pressure, head needle-like 3 presses at screw head, when reaching certain pressure, head needle-like 3 goes out the installing hole of the shape identical with head needle-like 3 at screw head, and head needle-like 3 is carried out spacing by pole 2 upper surface after entering, and punching press completes.
