Abstract
A stamping die for an automobile exhaust system casing comprises a male die (1) and a female die (2). The stamping die is characterized in that the male die (1) is composed of a male die main body (101) and a protruded block embedded lump (102), the shape of the male die main body is matched with a casing main body, the shape of the protruded block embedded lump is matched with the shapes of an air inlet port and an exhaust port on the casing, the protruded block embedded lump can be partially modified or replaced when the size of the position of an exhaust port of a stamping part becomes thin or exceeds the standard, replacement of the whole male die is avoided, and the die cost is reduced. The female die (2) is composed of a female die main body (201) and a concave block embedded lump (202), the shape of the female die main body is matched with the casing main body, the shape of the concave block embedded lump is matched with the shapes of the air inlet port and the exhaust port on the casing, the concave block embedded lump can be partially modified or replaced when galling occurs in the exhaust port of the stamping part, replacement of the whole female die is avoided, and the goal of reducing die cost is achieved. The stamping die is simple in structure and convenient to adjust.
Description
Technical field
The present invention relates to a kind of auto manufacturing technology, especially a kind of auto parts punch-forming mold, specifically a kind of automobile exhaust system housing diel.
Background technology
Fig. 1 is the contour structures schematic diagram of the gas extraction system housing in the J36R vehicle of Mazda, this housing need adopt the stainless steel of 1.2mm stamping, on housing, have three air inlet-outlet pipe connectors 4 that angle is different, the angle of the axial line of three air inlet-outlet pipe connectors and housing plane is all between 18-19 degree, this angle is different from the angle of 0 degree or 90, in punching course, material tensile deformation is difficult to control, and the wall thickness at three connector places of product requirement is all not less than 0.84mm after drawing and forming, but in actual punching course because mould is mostly monolithic construction, therefore, after batch production, can because die wear is inhomogeneous, occur that part connector wall thickness does not reach 0.84mm and occurs waste product, now, the mould that must more renew, cause die cost too high.In addition, in use it is found that, even when new die is used, three place's connectors all can meet wall thickness requirement, and connector place also there will be Zou and built material phenomenon, must punch and matrix repeatedly be repaired a die and could normally be used, cause the die debugging cycle long, service life is short, to this, and the solution there is no.
Summary of the invention
The object of the invention is for existing automobile exhaust system housing connector moulding difficulty large, long and service life in die debugging cycle short problem, design a kind ofly repair a die, automobile exhaust system housing diel easy to adjust.
Technical scheme of the present invention is:
The diel of a kind of automobile exhaust system housing, it comprises punch 1 and die 2, it is characterized in that described punch 1 inserted and 102 formed by punch main body 101 and projection, shape and the housing body of punch main body 101 match, the enterprising exhaust port shape of the shape of punch insert 102 and housing matches, described projection is inserted and 102 is carried out partial trim or replacing can or exceed standard in the size attenuation of stamping parts exhaust outlet position time, thereby avoids the replacing of whole punch, saves die cost; Described die 2 is inserted and 202 is formed by die main body 201 and recessed, shape and the housing body of die main body 201 match, the enterprising exhaust port shape of the shape of die plate insert 202 and housing matches, described die plate insert 202 can carry out partial trim or replacing when plucking appears in stamping parts exhaust outlet, thereby avoid the replacing of whole die, reach the object of saving die cost.
Surrounding at punch is provided with adjustable for height balance weight 3, the wrinkling or folded material phenomenon of integral body that this balance weight 3 can be eliminated stamping parts.
Beneficial effect of the present invention:
The present invention is by being designed to insert structure by protruding, recessed mold upper and connector relative position place, not only can not impact moulding, and can when debugging, take off easily and carry out partial trim or replacing, and repair without whole mould is taken off, more avoided changing the waste that unitary mould causes.It has finishing, changes conveniently advantage.Fundamentally guaranteed the wall thickness requirement of connector.
The present invention, by increase the method for balance weight on punch, has solved Zou that connector is prone to, has built material phenomenon, has guaranteed product quality, and easy to adjust.
Accompanying drawing explanation
Fig. 1 is the structural representation of stamping parts of the present invention.
Fig. 2 is the structural representation of punch of the present invention.
Fig. 3 is the structural representation of die of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As Figure 2-3,
The J36R vehicle gas extraction system housing diel of a kind of Mazda, it comprises punch 1 and die 2, described punch 1 is inserted and 102 is formed by punch main body 101 and three projections, as shown in Figure 2, three projections are inserted and 102 are spliced into punch main body 101 shape matching with Fig. 1 part drawing half shell inner chamber, projection is inserted and 102 both can have been realized detachable connection with punch main body 101 by connecting bolt, also can be by design the perfect adaptation that corresponding detent mechanism is realized both on punch frame, shape and the housing body of punch main body 101 match, the enterprising exhaust port shape of the shape of punch insert 102 and housing matches, described projection is inserted and 102 is carried out partial trim or replacing can or exceed standard in the size attenuation of stamping parts exhaust outlet position time, thereby avoid the replacing of whole punch, save die cost.Surrounding at punch is provided with adjustable for height 12 balance weights 3, the wrinkling or folded material phenomenon of integral body that this balance weight 3 can be eliminated stamping parts.Described die 2 is inserted and 202 is formed by die main body 201 and three recessed, as shown in Figure 3, the shape of die main body 201 and housing body outer wall match, the enterprising exhaust port shape of the shape of die plate insert 202 and housing matches, die plate insert 202 can be realized detachable connection with die main body 201 mutually by connecting bolt equally, also can realize connection between the two by the implementation structure on die frame, described die plate insert 202 can carry out partial trim or replacing when plucking appears in stamping parts exhaust outlet, thereby avoid the replacing of whole die, reach the object of saving die cost.Insert 102 position, size of die plate insert 202 and projection matches.
Using method of the present invention is:
Examination punching after punch and matrix is installed, if there is wrinkling or folded material phenomenon, first adjusts the height (increasing or reduce pad) of balance weight, until wrinkling or folded material phenomenon does not appear in the housing connector place of going out.With time can detect connector simultaneously simultaneously wall thickness whether be no less than 0.84mm, if there is the still wall thickness at a connector place to be less than 0.84mm, inserting of correspondence can be taken off and repaired, until wall thickness meets punching press requirement, and without whole mould is taken off and repaired.In use the phenomenon of as wrinkling in invention, folded material or wall thickness attenuation, can adjust respectively according to above-mentioned steps, and without mold exchange more.If use amount surpasses certain inspection limit, by finishing, cannot meet the requirement of connector wall thickness, the method that can insert by replacing solves, and without changing whole mould in city, not only saves die cost, and can improve debugging speed.
Part that the present invention does not relate to and blank holder, top mold frame, lower mold holder, knockout pin etc. all prior art that maybe can adopt same as the prior art are realized.
