Abstract
The invention discloses a kind of cone tank screw thread internal model, and it includes body, and the body has：Screw thread sizing section；Screw thread pre-profiling section, the front end of the screw thread pre-profiling section is connected with the rear end of the screw thread sizing section, and the cone tank that a plurality of axial direction along body is set in the shape of a spiral is provided with the screw thread pre-profiling section, the groove width of the cone tank is gradually reduced from front to back.The present invention can effectively make screw thread pre-profiling in advance in actual production process, reduce the frictional force of screw thread sizing section；The at the uniform velocity flowing of the metal in thread forming is effective to ensure that simultaneously, avoids metal in the rapid flow of screw thread sizing section, and causes wire drawing, the generation of curling problems.
Description
Technical field
The present invention relates to a kind of cone tank screw thread internal model.
Background technology
At present, the problem of being run into the production at present of normal thread internal model：
1st, the formation of whorl side corner and the requirement that phosphatization, lubrication and annealing process require are more harsh, easily cause screw thread
The fluctuation of side angle is big (not reaching or beyond standard requirement).
2nd, easily there is the problem of wire drawing, crimping in twisted steel.
3rd, easily there is the problem of turned-down edge in twisted steel.
4th, low production efficiency≤230 m/h.
The content of the invention
The technical problems to be solved by the invention are the defects of overcoming prior art, there is provided a kind of cone tank screw thread internal model,
It can effectively make screw thread pre-profiling in advance in actual production process, reduce the frictional force of screw thread sizing section；Simultaneously can be effective
Ground ensures the at the uniform velocity flowing of the metal in thread forming, avoids metal in the rapid flow of screw thread sizing section, and causes wire drawing, volume
The generation of side problem.
The present invention solves above-mentioned technical problem and adopted the technical scheme that：A kind of cone tank screw thread internal model, it includes body,
The body has：
Screw thread sizing section；
Screw thread pre-profiling section, the front end of the screw thread pre-profiling section are connected with the rear end of the screw thread sizing section, and
The cone tank that a plurality of axial direction along body is set in the shape of a spiral, the groove of the cone tank are provided with the screw thread pre-profiling section
Width is gradually reduced from front to back.
Further, the body also includes being used for the linkage section being connected with cold-drawn plug, the rear end of the linkage section and institute
State the front end connection of screw thread sizing section.
Further, the linkage section is screwed tooth structure.
After employing above-mentioned technical proposal, the cone tank set in screw thread pre-profiling section of the invention is by wide tapered, in reality
Screw thread pre-profiling can effectively be made in the production process of border in advance, reduce the frictional force of screw thread sizing section；It is effective to ensure that simultaneously
The at the uniform velocity flowing of metal in thread forming, avoids metal in the rapid flow of screw thread sizing section, and causes wire drawing, curling problems
Generation.
The present invention has following beneficial effect：
1st, whorl side corner is relatively stable, can be controlled in ± 10 ° substantially.
2nd, do not find that twisted steel has wire drawing, the generation of curling problems at present.
3rd, do not find that twisted steel has the generation of turned-down edge problem at present.
4th, production efficiency >=380 m/h.
Brief description of the drawings
Fig. 1 is the structural representation of the cone tank screw thread internal model of the present invention.
Embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail.
As shown in figure 1, a kind of cone tank screw thread internal model, it includes body, and the body has：
Screw thread sizing section 1；The main function of screw thread sizing section 1 for ensure big footpath size and screw thread in screwed pipe it is final into
Type meets technical requirements；
Screw thread pre-profiling section 2, the front end of the screw thread pre-profiling section 2 are connected with the rear end of the screw thread sizing section 1, and
And the cone tank 21 that a plurality of axial direction along body is set in the shape of a spiral, the taper are provided with the screw thread pre-profiling section 2
The groove width of groove 21 is gradually reduced from front to back.
As shown in figure 1, the body also includes being used for the linkage section 3 being connected with cold-drawn plug, the rear end of the linkage section 3
It is connected with the front end of the screw thread sizing section 1.
As shown in figure 1, the linkage section 3 is screwed tooth structure；The linkage section 3 is M16 × 1.5；Before the linkage section 3
End is also associated with the entity section of a diameter 12.
A diameter of the 20 of screw thread sizing section 1.
This internal model overall length 90mm；1 long 20mm of screw thread sizing section, 2 long 35mm of screw thread pre-profiling section, the length of linkage section 3 are
30mm。
The operation principle of the present invention is as follows：
The cone tank 21 set in the screw thread pre-profiling section 2 of the present invention, can be effective in actual production process by wide tapered
Ground makes screw thread pre-profiling in advance, reduces the frictional force of screw thread sizing section 1；It is effective to ensure that the metal in thread forming simultaneously
At the uniform velocity flow, avoid metal in the rapid flow of screw thread sizing section 1, and cause wire drawing, the generation of curling problems.
Particular embodiments described above, pair present invention solves the technical problem that, technical scheme and beneficial effect carry out
It is further described, should be understood that the specific embodiment that the foregoing is only the present invention, is not limited to this
Invention, within the spirit and principles of the invention, any modification, equivalent substitution and improvements done etc., should be included in this hair
Within bright protection domain.
