Description
Technical field: the utility model relates to a kind of metal stamping formed mould, relates in particular to a kind of automobile starter casing boss forming mould.
Background technology: the automobile starter casing is the metallic cylinder thin-walled parts, and its contour structures complexity, dimension precision requirement are higher.At present, the general processing method that adopts of a plurality of boss on the barrel is that elder generation with the boss punch forming, is rolled into cylinder and welding then on planar sheet.Shortcoming is: positional precision is not high, and is strict to equipment, and cost is big.
Summary of the invention: in order to overcome the deficiencies in the prior art, the utility model aims to provide a kind of simple in structure, accurate positioning, easy to operate, the metal stamping formed mould of automobile starter casing boss that can be used with common punch press.
The technical solution of the utility model comprises die shank, upper mould part, guide pillar, guide pin bushing and lower mould part; Described upper mould part is by the die shank that is fixed on the cope match-plate pattern upper surface, be fixed on two guide pin bushings in the cope match-plate pattern, be fixed on the backing plate of cope match-plate pattern lower surface by clamp, the stripper that is connected with cope match-plate pattern by bolt, be installed in a rubber between stripper and the clamp and an end and be fixed on the clamp other end extended formpiston from the through hole of rubber and stripper and form, described lower mould part is by being connected as a single entity with the former seat and being fixed on former bearing on the lower bolster, fixedly be embedded in the former mold insert on the former seat, be located on the former mold insert and the former consistent and be symmetricly set on a former seat axis left side with the formpiston shaped position, right both sides and angle are that 60 ° dowel hole is formed with an alignment pin that is installed in this hole; Described former seat is the cylinder on plane for the left and right sides, is symmetrical arranged left locating slot and right locating slot in the and arranged on left and right sides of dowel hole respectively along axis direction.
The lower surface of described stripper is and the consistent arc surface of former seat shape that the section configuration of described formpiston and former is rectangle.
Compared with the prior art, the utility model is owing to change original flat board as present cylinder into towards convex mold towards convex mold, thereby improved the positional precision of barrel convex platform, reduced the requirement of use equipment; In addition, therefore the former working position has reduced the loss of mould owing to adopted inserted interchangeable structure; Simultaneously, can finish the processing of a plurality of boss, reduce the input cost that mould is made with a secondary mould.

In the accompanying drawing: former seat 1 lower bolster 2 former mold inserts 3 alignment pins 4 strippers 5 rubber 6 clamps 7 formpistons 8 die shanks 9 backing plates 10 cope match-plate patterns 11 guide pin bushings 12 guide pillars 13 formers 14 dowel holes 15 left locating slot 16 former bearings 17 right locating slots 18
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In accompanying drawing 1,2, the upper surface of cope match-plate pattern 11 is fixed with 9, two guide pin bushings of die shank 12 and adopts the mode of interference fit to be fixed in the cope match-plate pattern 11, and backing plate 10 is pressed on the cope match-plate pattern 11 by clamp 7 usefulness bolts, its objective is protection cope match-plate pattern 11.Stripper 5 cooperates with screw on it by four bolts and is connected on the cope match-plate pattern 11, rubber 6 is installed between stripper 5 and the clamp 7 by this bolt, and central part, the other end that an end of formpiston 8 is fixed on clamp 7 pass from the unthreaded hole of rubber 6 and stripper 5.The former bearing 17 that is connected as a single entity with columniform former seat 1 is fixed on the upper surface of lower bolster 2; Consider easy to maintenance and economical with materials, fixedly inlay former mold insert 3 on the former seat 1, the shape, the position that are located at the former 14 on the former mold insert 3 are corresponding with formpiston 8; Being symmetrical in axis on former seat 1 has two dowel holes 15 and left and right locating slot 16,18 respectively, and alignment pin 4 is housed in the dowel hole 15.For the ease of location, the cylinder that former seat 1 scabbles for left and right sides face.The lower end of two guide pillars 13 is fixed on the lower bolster 2, the upper end is enclosed within above-mentioned two guide pin bushings 12.
During use, the utility model is installed on the punch press, workpiece is enclosed within on the former seat 1, make the notch alignment dowel hole 18 on the workpiece, insert alignment pin 4 then and get final product; After punching press is finished, take out alignment pin 4, workpiece is turned left 60 ° makes its notch alignment dowel hole 16, inserts the boss that alignment pin 4 can be processed the another location then.
Punch part for material thickness t 〉=2-5 millimeter blanking part needn't adopt the extrusion principle of metal flow to process, and can consider to adopt stamping-out mechanism to process.Be that formpiston size of the present utility model is determined principle below:
Shown in accompanying drawing 3,4, t-material thickness h-towards protruding height D-towards protruding diameter
If: d
Recessed-die diameter, d
Protruding-convex mould diameter, protruding, the die single face gap of Z-
Convex mould diameter is determined by common stamping mechanism, that is: stamping-out height h is determined by the thick t of material.So: d
Protruding=d
Recessed-(below the h * Z) * 2 is the occurrence of the utility model formpiston size, shown in accompanying drawing 5-8: L
Wide=2.5-(1.3 * 5%) * 2=2.37L
Long=6-(1.3 * 5%) * 2=5.87 is in the above in two formulas, because the material of automobile starter casing is No. 20 steel, so Z gets 5%.
