Abstract

Provided is a novel stamping die. The novel stamping die structurally comprises a male die and a female die matched with the male die. The novel stamping die is characterized in that an exhaust duct of which an air inlet and an air outlet are located in the bottom face and the side face of the male die respectively is arranged inside the male die; the tail end of the exhaust channel is provided with an oil storage tank which is connected with the air outlet through an oil drainage pipeline. The novel stamping die has the advantages that the exhaust duct is formed in an electric spark perforation mode, residual impurities such as oil and air between the male die and a part to be stamped can be discharged out through the exhaust duct, errors for stamping the part are eliminated, the stamping precision of the part is ensured, and therefore the technological requirement of the part is ensured, the production efficiency of the part is improved, the rejection rate is reduced, and the production cost is saved.

Description

A kind of diel
Technical field
The utility model belongs to pressing equipment technical field, relates to a kind of diel.
Background technology
In actual punching course, when the curved radius radius R size of Design of Dies hour, because of remnants between mould and part to be punched, there are the impurity such as oil and gas, cause the curved radius radius value of the part after punching press not reach the plane precision of technological requirement and part bottom inadequate, cause part cannot meet technological requirement.
Summary of the invention
The utility model is in order to solve the Accuracy to part punching that has the impurity such as oil and gas to cause due to remnants between mould and part, and then cause part cannot meet the technical problem of technological requirement, designed a kind of diel, in punch inside, offer exhaust passage so that the impurity such as remaining cold oil and air are discharged, to improve the punching precision of part.
The technical solution adopted in the utility model is: a kind of diel, and structure comprises punch and the die mating with it, key is: described punch inside is provided with the exhaust passage that air inlet and gas outlet lay respectively at punch bottom surface and side.
Described exhaust passage is manhole, and pore size is 3 ~ 5mm.
Described exhaust passage end is also provided with the oil storage tank being connected with gas outlet by oil extraction pipeline.
The beneficial effects of the utility model are: offering of exhaust passage can be by electric-spark drilling mode, by this exhaust passage, the impurity such as oil remaining between punch and part to be punched and air can be discharged, eliminate the error of punching parts, to guarantee the punching precision of part, and then guarantee the technological requirement of part, improving product production efficiency, reduce percent defective, save production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, the 1st, punch, the 2nd, die, the 3rd, part to be punched, the 4th, exhaust passage, 4-1 is vertically to passage, 4-2 is that level is to passage.
The specific embodiment
A diel, the die 2 that structure comprises punch 1 and mates with it, importantly: described punch 1 inside is provided with the exhaust passage 4 that air inlet and gas outlet lay respectively at punch 1 bottom surface and side.The impurity such as residual oil and gas enters the air inlet that punch 1 bottom surface arranges between with punching parts 3 and punch 1, then by discharging gas outlet, can further guarantee like this plane precision and the punching precision to curved radius radius with punching parts 3 bottoms.
Described exhaust passage 4 is manhole, and pore size is 3 ~ 5mm.
Further, for fear of the oil of being discharged by exhaust passage 4, again flow between punch 1 and part to be punched 3 or flow into die 2 and be with between punching parts 3 or diel is polluted, described exhaust passage 4 ends are also provided with the oil storage tank being connected with gas outlet by oil extraction pipeline.
Described exhaust passage 4 is by vertically forming to passage 4-2 to passage 4-1 and level, vertically the entrance to passage 4-1 is the air inlet that punch 1 bottom surface arranges, level is the gas outlet that punch 1 side arranges to the outlet of passage 4-2, the vertical outlet to passage 4-1 and level are joined to the entrance of passage 4-2, and vertically the outlet to passage 4-1 is positioned at apart from this vertically to passage 4-1 end 2 ~ 3mm position.Like this, the vertical outlet to passage 4-1 not being arranged to the vertical end to passage 4-1, is in order to play the effect of certain buffer gas flow pressure, makes toward the level of side more steady to passage 4-2 oil extraction, exhaust.
Further, in order to improve exhaust, oil extraction effect, described air inlet is positioned at the center of punch 1 bottom surface.
In the specific implementation, in punching parts process, utilize the mould being arranged on forcing press to treat punching parts 3 and exert pressure, make it produce separation or plastic deformation.At part 3 to be punched, occur in the process of plastic deformation, can because the curved radius radius R of punch 1 and die 2 designs is less and mould and part to be punched 3 between exist oil and air, cause the curved radius radius value of the part after punching press not reach technological requirement, and also can cause the plane precision for the treatment of punching parts 3 punching presses not reach requirement.Given this, as shown in Figure 1, bottom centre position at the punch 1 of diel group is used the mode of electric-spark drilling to do one vertically to passage 4-1, do in the same way again a level to passage 4-2, and make vertically to passage 4-1, to passage 4-2, to be communicated with to form exhaust passage 4 with level, and the vertical outlet to passage 4-1 is the end in this passage not, and the gas outlet of exhaust passage 4 is arranged at the side of punch 1.The impurity such as oil and gas are discharged to the assurance bottom surface craft precision of part punching and the technological requirement of curved radius radius when mould is treated punching parts 3 and exerted pressure from the side of punch 1 by exhaust passage.
