The punching die comprises a die shank, an upper die, guide sleeves, guide pillars and a lower die, wherein the upper die comprises an upper die plate (14), a clamping plate (4) fixed on the upper die plate, a stripper plate (4) arranged on the clamping plate; a rubber pad (5) arranged between the clamping plate and the stripper plate, and a male die fixed on the clamping plate (4); the die shank (1) and two guide sleeves (13) are fixed on the upper die plate (14); the lower die comprises a lower die plate (8), a support (10) fixed on the lower die plate, and a female die (9) fixed on the support; two guide pillars (12) are fixed on the lower die plate (8); and the guide sleeves (13) are sleeved on the guide pillars (12) respectively. The utility model has the advantages that the productivity is greatly improved, the manufacturing cost of a single product is reduced, and the service life is long.
Description
Technical field:
The utility model relates to a kind of mould, relates in particular to a kind of metal stamping formed mould.
Background technology:
The automobile starter casing is typical thin-walled shell class part, and its appearance structure more complicated, dimension precision requirement are higher; At present, normally utilize anchor clamps to adopt the method for milling to process the groove that is positioned at the end stop portion, its shortcoming is: productivity ratio is low, and the manufacturing cost height can not satisfy the needs of large-scale production.
Summary of the invention:
At the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of simple in structure, easy to operate, automobile starter casing seam groove punch die that productivity ratio is high.
To achieve these goals, the utility model by the following technical solutions: it comprises die shank, patrix, guide pin bushing, guide pillar and counterdie; Described patrix by cope match-plate pattern, be fixed on this cope match-plate pattern back side clamp, be arranged on this clamp back side stripper, be arranged on rubber blanket, an end between clamp and this stripper and be fixed on the formpiston that the other end on the clamp passes rubber blanket and stripper and constitute, die shank and two guide pin bushings are fixed on the cope match-plate pattern; Described counterdie by lower bolster, the former that is fixed on bearing on this lower bolster, is fixed on this bearing and is provided with die cavity constitutes, two guide pillars are fixed on the lower bolster; Patrix is arranged on two guide pillars by two guide pin bushings.
Be fixed with two guide fingers on stripper, this guide finger passes rubber blanket and inserts in the pilot hole that is located on the clamp; The end face of formpiston is a terraced structure, is fixed with on the former and inserts, and this is inserted and is provided with die cavity; Be fixed with backing plate between cope match-plate pattern and the clamp; The lower surface of stripper is the arc surface that matches with the former shape.
Compared with the prior art, the utility model has been owing to substituted Milling Process with punch process, and adopted technique scheme, therefore increased substantially the automobile starter casing productivity ratio, reduced the single-piece manufacturing cost; In addition, because the yin, yang mould of mould sharpening after wearing and tearing is all very easy with replacing, therefore prolonged the service life of mould.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view among Fig. 1.
Among the figure: die shank 1 formpiston 2 guide fingers 3 clamps 4 rubber blankets 5 strippers 67 lower bolsters, 8 formers, 9 bearings, 10 die cavitys, 11 guide pillars, 12 guide pin bushings, 13 cope match-plate patterns, 14 backing plates 15 of inserting
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～2, be fixed with 1, two guide pin bushing of die shank 13 at the top of cope match-plate pattern 14 and adopt the mode of interference fit to be fixed in the cope match-plate pattern 14; Clamp 4 is fixed on the back side of this cope match-plate pattern by screw, the back side of this clamp is to be connected stripper 6 on the cope match-plate pattern 14 by bolt, rubber blanket 5 is arranged between clamp 4 and this stripper, and an end of formpiston 2 is fixed on the clamp 4, the other end passes rubber blanket 5 and stripper 6 stretches out downwards.Be fixed with bearing 10 and two guide pillars 12 on lower bolster 8, former 9 is fixed on this bearing, and the position corresponding to formpiston 2 on former 9 is provided with the die cavity 11 adaptive with this formpiston.Two guide pin bushings 13 are enclosed within on two guide pillars 12.In order to improve the stability of formpiston 2, simultaneously also in order to improve precision, on stripper 6, be fixed with two guide fingers 3, this guide finger passes rubber blanket 5 and inserts in the pilot hole that is located on the clamp 4.Owing to the size of formpiston 2 is carefully grown, therefore crooked easily or fracture can improve its rigidity by increasing its sectional dimension; For this reason, the end face of formpiston 2 adopts terraced structure.Damage for fear of former 9, be fixed with on former 9 and insert 7, this is inserted and is provided with the die cavity 11 adaptive with formpiston 2.In order to protect cope match-plate pattern 14, between cope match-plate pattern 14 and clamp 4, be fixed with backing plate 15 by screw; In order to improve the stability of stripper 6, the arc surface that matches with former 9 shapes is adopted in the lower surface of this stripper.
