Description
Technical field
Screw production technology is the utility model is related to, more particularly to a kind of dental lamina mould for being used to produce anti-broken screw.
Background technology
In equipment assembling and repair procedures, due to the reason such as excessive of being exerted oneself when assembling or dismount corrosion screw, screw
It may all be twisted off, a part of stud is stayed in equipment and be not easily taken out, and influence follow-up work.In order to prevent such case from going out
Now, it is necessary to be improved to the structure of screw, and conventional thread rolling dental lamina mould is difficult to meet to require.Therefore, it is necessary to tooth
Board mold carries out structure optimization, to overcome drawbacks described above.
Utility model content
The purpose of this utility model is to provide a kind of dental lamina mould for being used to produce anti-broken screw, is easy to anti-broken end spiral shell
Silk is processed.
The utility model is that technical scheme is used by solving its technical problem：
For producing the dental lamina mould of anti-broken screw, including quiet dental lamina and dynamic dental lamina, quiet dental lamina are installed in quiet die cavity,
Dynamic dental lamina is installed in dynamic model groove, and quiet dental lamina has with having the gear rolling being mutually adapted on dynamic dental lamina between quiet dental lamina and dynamic dental lamina
There is the gap passed through for screw blank, wherein：
Gear rolling is located on the working face of quiet dental lamina and dynamic dental lamina, and gear rolling is provided with some, and is sequentially arranged along working face, rubs with the hands
It is parallel to each other between tooth, the axial direction of each gear rolling and quiet dental lamina and dynamic dental lamina is in a certain angle；
There is ending chamfering section positioned at the gear rolling of screw-thread ending section, ending chamfering section is located at the feed end of gear rolling, and ending is fallen
The tooth form radian of angle section constantly becomes big, height constantly rise, until being linked up smoothly with gear rolling, screw is finished up by ending chamfering section
The screw thread of section is twisted.
In one embodiment of the present utility model, ending chamfering section includes the first chamfering section, the second chamfering section and the 3rd
Chamfering section, the length of the first chamfering section, the second chamfering section and the 3rd chamfering section be respectively finish up chamfering section total length three/
One, the length of the first chamfering section, the second chamfering section and the 3rd chamfering section is respectively the length of a circle screw thread.
Specifically, the ending chamfering section apical side height of adjacent gear rolling constantly reduces, and is located along the same line, the straight line with
The angle of working face is 5 °~45 °.
The utility model has the advantage of：
Anti- broken screw processing can be carried out using the dental lamina mould, blank enters between dental lamina in meditation and dynamic dental lamina, and first falls
Angle section, the second chamfering section and the 3rd chamfering section twist a circle screw thread respectively, the tooth bottom of screw-thread ending section is constantly raised, and maincenter
It is constantly thicker, so as to increase the intensity of thread segment and screw head junction, avoid in installation with breaking end in unloading process.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines diagram and specific embodiment, and the utility model is expanded on further.
The utility model proposes the dental lamina mould for being used to produce anti-broken screw include quiet dental lamina and dynamic dental lamina, quiet dental lamina
It is installed in quiet die cavity, dynamic dental lamina is installed in dynamic model groove, and quiet dental lamina is with having the gear rolling being mutually adapted, quiet dental lamina on dynamic dental lamina
There is the gap passed through for screw blank between dynamic dental lamina, as shown in Figure 1, Figure 2, Figure 3 shows, due to moving the stranding of dental lamina and quiet dental lamina
Toothing is consistent, and the structure of dynamic dental lamina is only show in figure, and gear rolling 1 is located on the working face of dynamic dental lamina 2, and gear rolling is provided with some
Bar, and sequentially arranged along working face, it is parallel to each other between gear rolling, the axial direction of each gear rolling and quiet dental lamina and dynamic dental lamina is in a clamp
Angle；There is ending chamfering section positioned at the gear rolling of screw-thread ending section, ending chamfering section is located at the feed end of gear rolling, ending chamfering section
Tooth form radian constantly becomes big, height constantly rise, until being linked up smoothly with gear rolling, the spiral shell for the section that finished up by ending chamfering section to screw
Line is twisted.Such as Fig. 2, in the present embodiment, ending chamfering section is fallen including the first chamfering section R1, the second chamfering section R2 and the 3rd
Angle section R3, the length of the first chamfering section, the second chamfering section and the 3rd chamfering section be respectively finish up chamfering section total length L three/
