Description

Punching die
Technical field
The utility model relates to a kind of mould, is exactly a kind of punching die specifically.
Background technology
When using stamping machine to carry out punching press, a cover diel all can be installed in it, every cover diel correspondence stamps out a kind of part.The part that has has centre bore, and the upper surface of this part is provided with step surface, therefore, need the diel supporting with it realize punch forming.
Summary of the invention
The utility model provides a kind of punching die in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of punching die, comprises middle mould, offer middle nib on the middle mould, also comprise the upward outer punch die above the nib in the insertion, and the following punch die below the nib in the insertion, punch die was offered upper punch nib and following punch die hole respectively under upward outer punch die reached; Also comprise the interior punch die of going up that inserts in the upper punch nib, and insert the plug in punch die hole down; Also comprise the central through hole on the punch die in being opened in; Plug inserts in the central through hole of going up interior punch die with the following punch die hole on the following punch die.
The utility model is compared with prior art, and the utility model is simple in structure, punching press is convenient, and the center of being applicable to has the stamping parts that centre bore and upper surface have step surface.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1,1 is middle mould; 2 is middle nib; 3 is last outer punch die; 4 are following punch die; 5 is the upper punch nib; 6 are following punch die hole; 7 is last interior punch die; 8 is plug; Through hole centered by 9.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the utility model comprises middle mould 1, offers middle nib 2 on the middle mould 1, also comprises the upward outer punch die 3 of nib 2 tops in the insertion, and the following punch die 4 of nib 2 belows in inserting, go up outer punch die 3 and down punch die 4 offer upper punch nib 5 and following punch die hole 6 respectively; Also comprise the interior punch die 7 of going up that inserts in the upper punch nib 5, and insert the plug 8 in punch die hole 6 down; Also comprise the central through hole 9 on the punch die 7 in being opened in; Plug 8 inserts in the central through hole 9 of going up interior punch die 7 with the following punch die hole 6 on the following punch die.
The course of work of the present utility model is as follows: fill metal dust earlier in the middle nib 2 of middle mould 1, again successively outer punch die 3 in the sequence starting, go up in punch die 7, punch die 4 down, top in making outer punch die 3 therefrom mould 1 inserting in the nib 2, punch die 7 inserts in the upper punch nibs 5 in going up.Simultaneously, following punch die 4 is during therefrom mould 1 downside inserts in the nib 2.At this moment, go up the stamping surface of outer punch die 3 and the stamping surface of last interior punch die 7 and from the metal dust upside it is pushed, the stamping surface of following punch die 4 pushes it from the metal dust downside.Because the upper and lower both sides of metal dust are extruded simultaneously, make it be compressed in extrusion modling in the die cavity.At last, start plug 8, make plug be inserted in down in the central through hole 9 on the punch die and in passing nib 2 backs insert in the upper punch nib of going up on the interior punch die 75.So, in forming part, be formed centrally centre bore.
Compare with prior art, the utility model is simple in structure, punching press is convenient, and the center of being applicable to has the stamping parts that centre bore and upper surface have step surface.
