Description
Technical field
The utility model relates to a kind of mould structure, particularly relates to the adjustable of a kind of stamping-out aperture and rushes formula mould.
Background technology
Have the situation of stamping-out aperture on small parts during stamping, position degree between aperture and datum hole require and centre-to-centre spacing franchise all very strict.Particularly in watch part stamping-out, circular hole requires to be generally 0.016-0.02mm for the position degree of datum hole.When stamping-out as there is overproof can improvement by regulating the method for locating pin position.But during for stamping-out aperture on small parts, its relative position degree requires the vital part reaching 0.007-0.01mm, its punching precision is not significantly improved by above-mentioned means, Fig. 1 is existing mold structural representation, as there is position degree or profile tolerance is overproof, just need, by mach method, upper/lower die plate is carried out repeatedly repair, until position and profile requirements qualified carry out again die assembly, examination punching.Repeated multiple times until go out qualified parts; Repeatedly the process of repair not only can cause original nail positional precision loss, and processing cost and installation time can be made to be multiplied.This situation especially easily occurs when spare part outside measurement is little and institute rushes aperture position precision height, often causes mould parts to scrap.In addition, the existing mold drift tiny because structure limits because length and diameter disproportionate and affect intensity, directly affects precision and the service life of mould.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of mould positioning precision to improve, and repair effect promoting, the adjustable of stamping-out aperture that the life-span is high, scrappage is low rush formula mould.
The technical scheme that the utility model adopts is, the adjustable of a kind of stamping-out aperture rushes formula mould, comprises, locating pin, stripper, little guide pillar, slide block, base, die, drift, punch fixing plate, rubber washer and die shoe; Be arranged on slide block in described die shoe and base to be bolted and to be integrated, die shoe can slide along the targeting part of slide block; Fixed head and slide block are fixed as one, and fixed block are provided with drift and little guide pillar; Described stripper and die shoe are fixed as one, and stripper is provided with locating pin, and described die is fixed by screw and pin and patrix, and the bottom of die is formed with the groove corresponding with locating pin; On stripper and be formed with drift and little guide pillar can the through hole of relative sliding; Between described base and die shoe, rubber washer is installed, and is bolted and is integrated.
Described parts fixation is on stripper.
Also include additional positioning mechanism, described additional positioning mechanism comprises retainer ring and spacer, retainer ring and spacer are fixed on one by joint bolt, the center of spacer is formed with the shape suitable with part, adjusting play A is formed between the internal diameter of described retainer ring and the external diameter of stripper, the outside circumference of retainer ring is evenly provided with adjustment screw, the radial clearance A between adjustment stripper and retainer ring.
The thickness of described spacer is identical with part to be processed, is combined closely by screw at the periphery spacer of processing parts and stripper.
Described drift and leave certain gap between little guide pillar and fixed head, the axial float of fixed head restriction drift and little guide pillar.
Described drift and leave the gap of 0.002mm between little guide pillar and stripper.
The beneficial effects of the utility model are, because mould positioning reference plane and stamping-out face overlap, avoid Datum transfer, make mould repair effect promoting; Because punch length shortens, its intensity is strengthened, and die life improves; Mould repair, adjustment process simplify.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figures 1 to 5, the adjustable of the utility model stamping-out aperture rushes formula mould, comprises, locating pin 1, stripper 2, little guide pillar 3, slide block 4, base 5, die 6, drift 7, punch fixing plate 8, rubber washer 10 and die shoe 11; Described die 6 is fixed by screw and pin and patrix, the slide block 4 be arranged in described die shoe 11 is bolted to connection with base 5 and is integrated, the fixed head 8 be connected with slide block 4, drift 7 and little guide pillar 3 all do not move, when counterdie is descending, die shoe 11 can slide along the targeting part of slide block 4; Fixed head 8 and slide block 4 are fixed as one by screw and straight pin, fixed block 8 are provided with drift 7 and little guide pillar 3, drift 7 and leave certain gap between little guide pillar 3 and fixed head 8, and fixed head 8 limits the axial float of drift 7 and little guide pillar 3; Described stripper 2 is fixed as one with die shoe 11, and stripper 2 is provided with locating pin 1 and part 17, the bottom of die 6 is formed with the groove corresponding with locating pin 1; On stripper 2 and be formed with drift 7 and little guide pillar 3 can the through hole of relative sliding, drift 7 and leave the clearance sliding fit of 0.002mm between little guide pillar 3 and the stripper 2 with guide effect; Between described base 5 and die shoe 11, rubber washer 10 is installed, and is bolted and is integrated.
When needing the External Shape of stamping-out very little or take profile as its overview of inspection benchmark, additional positioning mechanism can be increased to realize outside fix and precision adjustment on mould.As described in Figure 4, additional positioning mechanism comprises retainer ring 13 and spacer 12, retainer ring 13 and spacer 12 are fixed on one by four joint bolts 14, the center of spacer 12 is formed with the shape suitable with part 17, the thickness of spacer 12 is identical with part to be processed 17, for the location to part 17, in processing parts 17 shape surrounding, spacer 12 is fixed in stripper 2 plane with three hold-down screws 15 during stamping-out; Adjusting play A is formed between the internal diameter of described retainer ring 13 and the external diameter of stripper 2, the outside circumference of retainer ring 13 evenly installs 4-6 adjustment screw 16, when needs adjustment part positioning precision, namely need to regulate the relative position on spacer 12 between External Shape and drift 17.As, unclamp hold-down screw 15, turn two adjustment screws 16 to angular direction gently with screwdriver, change the radial clearance A between stripper 2 and retainer ring 13, after having regulated a direction, then change other direction continuation diagonal angle adjustment; Coordinate examination punching, test stage, until after putting and adjusting, then spacer 12 position of being tightened by hold-down screw 15 to determine to regulate no longer changes, namely, the precision of stamping-out is ensured by the machining high-precision of stripper 2, avoids the impact of Datum transfer on mould and die accuracy.Occur position degree overproof time, only need repair be fixed on stripper 2 locating pin or repair stripper 2 on just can well the dealing with problems of position of working hole.
Working method of the present utility model is:
As shown in Figure 5, when stamping-out starts, patrix is descending, die 7 is more and more close to stripper 2, when die 7 and clamping when the part 17 on stripper 2 surface contacts stripper 2 just along with patrix is descending together, and estimate die shoe 11 and compress rubber washer 10 along slide block 4 glide downwards, and the downward sleeve pipe 9 that promotes slides up and down in base plate 5 simultaneously, along with die shoe 11 is descending, the slide block 4 be fixed together with base plate 5 and fixed head 8 can not move up and down, just by part punching thoroughly, then patrix is up, completes a stamping-out for drift 7 fixed thereon.
