Description
Technical field
The utility model belongs to bolt manufacture field more particularly to a kind of bolt forming die.
Background technique
Bolt in daily life and industrial production and manufacturing, be it is essential, bolt is also referred to as rice of industry.Bolt
Operation strategies include electronic product, engineering goods, digital product, power equipment, electromechanical engineering goods etc..
Interior hexagonal cylindrical headdress flower tooth bolt is as one of common bolt, and flower tooth processing method is generally in bolt hair
Cylindrical die roll on base using screw-rolling machine is processed on polished rod to be obtained spending tooth, but the size of colored tooth obtained by the above method is uneven,
The size and number of tooth is difficult to control accurately.In addition, also have the technique that flower tooth bolt is produced using flower tooth mold in the prior art,
But the flower tooth die bolt generally used in above-mentioned technique is difficult to be subjected to repeatedly to squeeze, and die life is short, and when more mold exchange needs
Integral replacing, production cost are higher.
Utility model content
Technical problem to be solved in the utility model is to overcome the shortcomings of to mention in background above technology and defect, is provided
A kind of machining accuracy is high, is easy to the low interior hexagonal cylindrical headdress flower tooth bolt of disassembling, assembling and replacing, production cost spends tooth processing shaping mould
Tool.In order to solve the above technical problems, the utility model proposes technical solution are as follows:
A kind of interior hexagonal cylindrical headdress flower tooth bolt flower tooth processing molding die, including mold shell, the mold shell
It is interior it is intracavitary be removably installed with colored tooth matrix and screw rod matrix, the inner cavity shape after the colored tooth matrix and the combination of screw rod matrix
The shape of shape and the interior hexagonal cylindrical headdress flower tooth bolt matches.
In above-mentioned molding die, it is preferred that the mold shell includes upper shell and lower casing, the upper shell and lower outer
Shell is detachably connected by screw thread；The inner cavity internal diameter of the lower casing is less than the inner cavity internal diameter of the upper shell, the screw rod mould
The top half of piece is located at the interior intracavitary of the upper shell, and the lower half portion of the screw rod matrix is located at the inner cavity of the lower casing
It is interior.It, on the one hand can be by flower tooth matrix and screw rod die attachment in the inner cavity of mold shell, separately using the design of upper lower casing
On the one hand it is also convenient for replacing colored tooth matrix and/or screw rod matrix, dismount more convenient.
In above-mentioned molding die, it is preferred that the top of the upper shell is in back taper, and the colored tooth matrix passes through screw rod mould
Piece pressure is set in the back taper chamber.Flower tooth matrix can be fixed under the action of shell on screw rod matrix and back taper
In back taper chamber.
In above-mentioned molding die, it is preferred that the colored tooth matrix includes that wolfram steel flower tooth nest plate is spent with the wolfram steel is sheathed on
Steel flower tooth outside tooth nest plate covers loop；The screw rod matrix includes wolfram steel mold core and the steel that is sheathed on outside the wolfram steel mold core
Mold core ring.Wolfram steel flower tooth nest plate is externally provided with steel flower tooth set loop, wolfram steel mold core is externally provided with steel mandrel ring and can reduce stress,
Extend the service life of wolfram steel flower tooth nest plate and wolfram steel mold core.
In above-mentioned molding die, it is preferred that the lumen centers axis phase of the mold shell, flower tooth matrix and screw rod matrix
Mutually overlapping.Each lumen centers axis is overlapped can to guarantee that entire molding die stress is more balanced, and each component uses the longevity
It orders longer.
In above-mentioned molding die, it is preferred that the screw rod matrix is split type structure, by least two combination matrix edges
The axial direction of mold shell inner cavity is overlapped mutually.In processing bolt, the stress condition of screw rod matrix different parts is often deposited
Difference (axial direction usually along mold shell inner cavity has differences), breakage occurs in screw rod matrix, and to be frequently experienced in stress bigger
Position, when using monoblock type screw rod matrix, when a certain small position is impaired, that is, need integral replacing.Using split type screw rod

It can be integral with steel flower tooth set loop).Preferably, the transition matrix also is located in the back taper chamber.Work as production
Bolt require bolt cylindrical head when being not all the colored flank of tooth, a mistake can be added in flower tooth mold and the intermediate of screw rod mold
Matrix is crossed, so that bolt cylindrical head reserves even surface.This is also further embodied using shaping mould in the utility model
The advantage of tool uses Split type die in the utility model, can be combined with multiple small matrixs, to be suitable for different bolts
It is different require, this is the unapproachable advantage of monoblock type molding die.
In above-mentioned molding die, it is preferred that the lumen centers axis of the transition matrix and the lumen centers of flower tooth matrix
Axis is overlapped, and the overall thickness of the transition matrix and flower tooth matrix is identical as the bolt cylindrical head height.
The utility model also provides a kind of method of above-mentioned interior hexagonal cylindrical headdress flower tooth bolt forming die processing bolt, packet
Include following steps:
(1) bolt blank with round table-like head and circular columns screw rod is processed by a mould one punching, the punching of two moulds two；Its
In, round table-like head upper end is big, and lower end is small；
(2) bolt blank obtained in step (1) is put into above-mentioned interior hexagonal cylindrical headdress flower tooth bolt forming die,
Under the hexagonal stamping rod effect of punch die, Hexagon hole is gone out on round table-like head, and is squeezed out colored dentation and obtained spending dentation bolt；
(3) processing threaded blank diameter on the flower dentation bolt obtained in step (2), the i.e. processing of completion bolt.
In the method for above-mentioned processing bolt, it is preferred that the round table-like head of bolt blank obtained in rate-determining steps (1)
Height is greater than the overall thickness of colored the tooth matrix and transition matrix.The round table-like head one of bolt blank obtained in step (1)
As its outer diameter be less than the internal diameter of flower tooth bolt, when three moulds three rush, round table-like head can longitudinal compression, to squeeze out colored tooth, therefore
It is required that the height on round table-like head is greater than the overall thickness of colored the tooth matrix and transition matrix.Certainly, if being used without transition
When the molding die of matrix adds formula bolt, the height on round table-like head is greater than the thickness of the colored tooth matrix.
Compared with the prior art, the advantages of the utility model are:
1, in processing bolt, molding die stress is often uneven, and often certain places have already appeared breakage to molding die,
And it is certain local or intact, but it is also required to integral replacing at this time, higher cost.The interior hexagonal cylindrical head of the utility model
Flower tooth matrix and screw rod matrix in flower tooth bolt flower tooth processing molding die are not an entirety (i.e. split-type design), no
Only assembly and disassembly is convenient, and when some matrix is impaired, is not necessarily to integral replacing mold, only needs to change impaired matrix i.e.
Can, production cost can be greatly reduced.
2, the interior hexagonal cylindrical headdress flower tooth bolt flower tooth processing of the utility model uses split-type design with molding die, respectively
Kind matrix can be used in any combination, can be significantly using various forms of bolts can be processed after different matrix simple combinations
