Description
Technical field
The utility model is related to a kind of molds, more particularly, to a kind of contact chip diel；
Background technology
Diel is the mold detached for sheet metal forming and blanking, including blanking die, bending die, Drawing Die and
Plunging die etc..In diel, by mold cavity to sheet forming, plate is implemented by the punching cutting edge of diel
Separation or cutting.
In the research process for carrying out the utility model, utility model people has found the diel using the above-mentioned prior art
There are following technological deficiencies：Existing diel punch components are usually integrally formed, and a damage is easy to cause entire mold
Damage, and usually there is independent guider and device for discharging, thus lead to complicated, the processing technology of diel
Complexity, production cost are high；It is easy to take up workpiece meanwhile in the course of work of diel, when upper mold resets, causes workpiece
Dislocation, device for discharging is difficult to eject workpiece, unloading difficulties, and safety is poor.
Utility model content
A kind of contact chip diel of the utility model offer can simplify punching to solve defect in the prior art
The structure of compression mould, the difficulty for reducing processing technology reduce production cost and discharging simplicity, safe operation.
A kind of contact chip diel, including upper die holder and lower die holder, are fixed with guide post on lower die holder, fixed on upper die holder
There are the guide sleeve coordinated with guide post, the upper surface of the upper die holder to be fixed with flange die shank, the lower surface of upper die holder is fixed with backing plate,
Backing plate is fixed with punch retainer by the second screw, and several punch retention holes, punch retention hole are formed on punch retainer
Inside it is fixed with bending punch, cut-out punch-pin, the first piercing punch and the second piercing punch；Bending punch, cut-out punch-pin, the first punching
Hole punch-pin and the second piercing punch lower part be all connected with stripper and top is all connected with evagination and is formed with and coordinates with punch retention hole
Baffle ring；Stripper is connected with guide pin；The stripper is elastic stripper, such as plastics stripper, rubber stripper plate.Discharging
Plate is fixedly linked by unloading bolt and upper die holder；It is fixed with connecting plate on the lower die holder, is formed on connecting plate and guide
The through-hole of pin, the first piercing punch and the cooperation of the second piercing punch.
Further to improve, the cut-out punch-pin is made of small one and large one two semicolumns；
Further to improve, second piercing punch is the round punch for having convex shoulder；
Further to improve, second piercing punch surface is equipped with protective film.
Further to improve, the upper die holder is fixedly linked with flange die shank by third screw.
The utility model has the beneficial effects that：Necessary in the utility model simple structure and reasonable design, saving punching press
The protective film that power while recessed film, punching convex film surface are equipped with reduces the contact between the diel and stamping material of steel,
Diel accelerated oxidation caused by different metal contacts is reduced, extends the service life of diel, while bending punch,
Cut-out punch-pin, the first piercing punch and the second piercing punch are detachably arranged, and are replaced after a damage, will not cause entire
Mold is scrapped.

Specific implementation mode
To keep the purpose of this utility model, technical solution and advantage clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
It is the utility model a part of the embodiment to apply example, instead of all the embodiments.Based on the embodiments of the present invention, ability
It is new to belong to this practicality for the every other embodiment that domain those of ordinary skill is obtained without creative efforts
The range of type protection.
Embodiment 1
A kind of contact chip diel, including upper die holder 1, lower die holder 28, stock guide 22, positioning plate 3, guide pin 12, on
Die holder 1 is connected by screw 6 with backing plate 11, punch retainer 16, and lower die holder 28 is connected by screw 26 with connecting plate, described
Punch retainer 16 has opening, bending punch 7, cut-out punch-pin 10, guide pin 12, the second piercing punch 14, unloading bolt 15 to divide
Not Chuan Guo trepanning be connected with stripper 17, which is characterized in that the stripper 17 is elastic stripper；The guide pin 12 can be with
Control billot feeding cloth away from；The cut-out punch-pin 10 is made of small one and large one two semicircles；Second piercing punch 14 is
There is the round punch of convex shoulder；
First, upper die holder and lower die holder are fastened, flitch is then cutting into billot according to the width of setting；Billot is sent
Enter stock guide, into feed inlet, start hydraulic press, hydraulic press downlink applies pressure to punch retainer, driving bending punch to
Cavity plate moves, and realizes punching press-blanking.
The description of the above examples is only intended to facilitate the understand of the core idea of the present invention；Meanwhile for the general of this field
