Column-shaped is arranged, and the position of flexible support portion corresponds to the edge of external mold 3 so that flexible support portion to the support of external mold 3 more
Stablize.Matrix 5 is tubular structure, and lateral surface is equipped with decorative pattern, so that the inner surface of a beading is pressed into corresponding decorative pattern, improves a beading
Binding force between matrix and carcass.
The ontology of mold core 6 is cylinder, and the bottom end of mold core 6 is equipped with mold core step column 61, and the outer diameter of matrix 5 is less than mold core 6
Ontology diameter；The ontology of push-down head 4 is cylinder, and the top of push-down head 4 is equipped with pressure head step column 41, mold core step column 61
And the diameter of pressure head step column 41 is slightly less than the internal diameter of matrix 5, so that the lateral surface of mold core step column 61 and pressure head step column 41
It is slidably matched with the endoporus hole wall of matrix 5, the sum of pressure head step column 41 and the length of mold core step column 61 are less than or equal to base
The length of body 5, this makes it possible to matrix 5 and mold core 6, push-down head 4 are accurately positioned.
Seaming chuck 7 is tubular structure, and the upper end of seaming chuck 7 is equipped with the round platform 71 that outer diameter is more than 31 diameter of die hole, to avoid
Seaming chuck 7 falls in die hole 31 while increases the compression strength of seaming chuck 7；The diameter of 6 ontology of mold core is slightly less than seaming chuck 7
Internal diameter so that the endoporus hole wall of the outer body face of mold core 6 and seaming chuck 7 is is slidably matched, the diameter of seaming chuck 7 and pushing
First 4 outer diameter is identical, and is slightly less than the aperture of the die hole 31 of external mold 3, so that the lateral surface of seaming chuck 7, the outside of push-down head 4
Hole wall of the face with the die hole of external mold 3 31 is slidably matched.
The side of external mold 3 is additionally provided with vertical pilot hole 32, and the protrusion of pedestal 2 is equipped with and 32 corresponding lead of pilot hole
24, during external mold 3 moves up and down, lead 24 can be to avoid 3 run-off the straight of external mold.Certainly, pilot hole 32 is had to
Die hole 31 is avoided, causes to interfere to avoid to the production of a beading.
Resetting block 8 is platy structure, and bottom surface is equipped with position reset post 81 corresponding with 31 position of die hole of external mold 3, described
The diameter of reset post 81 is less than the diameter of die hole 31.
In the present embodiment, the endoporus aperture of seaming chuck 7 is 8.05mm, a diameter of 10.8mm of ontology, and round platform 71 is a diameter of
15.4mm；The a diameter of 8.00mm of ontology of mold core 6, a diameter of 4.95mm of mold core step column 61；The ontology of push-down head 4 is a diameter of
10.8mm, a diameter of 4.95mm of pressure head step column 41；The outer diameter of matrix 5 is 7.95mm, internal diameter 5.00mm.The mould of external mold 3
The gap of 31 inner wall of hole and seaming chuck 7, push-down head 4 is 0.04~0.08mm.
Using above-mentioned beading cold stamping die（It is used cooperatively with the punch 10 of vertically-acting）Beading production method specifically include
Following steps：
A：Knockout pin 21 on pedestal 2 and the bottom end of push-down head 4 are offseted, push-down head 4 is inserted upwardly into the die hole of external mold 3
31, so as to which external mold 3 to be supported in the top of pedestal 2 using flexible support portion；Then matrix 5 is sleeved on to the pressure head platform of push-down head 4
On rank column 41, then mold core 6 is put into the die hole 31 of external mold 3, and the mold core step column 61 of mold core 6 is caused to be inserted downwardly into base
In the endoporus of body 5；At this point, between the die hole 31 of external mold 3 and matrix 5 formed an annular recess, the shape of the recess portion with it is to be generated
The shape of a beading for production is identical；
B：Diamantiferous alloyed powder is poured into the die hole 31 of external mold 3, is then placed in seaming chuck 7, and cause 7 sets of seaming chuck
Enter onto the ontology of mold core 6；
C：It manipulates punch 10 to move down, applies downward pressure to seaming chuck 7 using punch 10, in seaming chuck 7 and push-down head 4
（Push-down head 4 is demolded bar 21 and resists, and can not move down）Under the action of, it is a beading by diamantiferous alloyed powder cold moudling
Carcass 9（Specific pressure can be set according to actual needs）, state is as shown in Figure 2 at this time；
D：Punch 10 is removed upwards, demoulding block 1 is placed between external mold 3 and punch 10, then moves down punch 10 again,
Apply downward pressure to demoulding block 1 using punch 10, demoulding block 1 pushes external mold 3 to move down, since push-down head 4 is demolded at this time
Bar 21 resists, and can not move down, therefore will not be moved down with external mold 3, during external mold 3 moves down, a beading
Carcass 9 is gradually exposed to the die hole 31 of external mold 3, and state is as shown in figure 3, realize demoulding at this time, you can removes beading carcass 9；So
After remove punch 10 and demoulding block 1, external mold 3 is moved upwards under the action of 23 elasticity of spring and is resetted, finally by resetting block 8
Reset post 81 is inserted downwardly into the die hole 31 of external mold 3, so as to which push-down head 4 be resetted downwards.
Certainly, beading carcass 9 obtained above will also carry out hot pressing, due to unrelated with beading cold stamping die,
Details are not described herein again.
Repeat above-mentioned A~D steps, you can repeat the production of a beading, without being torn open again between producing twice
Cold stamping die is filled, is greatly improved work efficiency, more it is essential that the die hole 31 for being used to suppress a beading in cold stamping die is not by two
The assembly of block structure body, but be integrally formed inside external mold 3, the weight of the beading carcass 9 of acquisition is consistent with size, therefore
It can ensure the quality of a beading.
