Description
Technical field
This utility model relates to cold-punching mould structure-design technique field, particularly relates to a kind of flanging and restriking cold-punching mould Self-resetting wedge structure.
Background technology
Cold-punching mould is a kind of high-precision process equipment, and designing and producing of cold-punching mould is the machining accuracy according to part to be processed and the Complicated design mould that gone out each molding procedure of part.Forming parts process generally comprises these five molding procedure of drawing, trimming, flange, entirety and punching.Correspondingly, cold-punching mould needs to design five secondary moulds altogether: Drawing Die, edger, flange die, sizing die, perforating die.Owing to design and the processing cost of mould are high, and increasing of number of molds needs correspondence increase the quantity of forcing press and elongate the technological process of part, is greatly increased design and equipment cost.It is true that above-mentioned five moulds have the operating procedure that part is identical, can be by the structure of mould be reasonably arranged so that a secondary mould realizes two or more manufacturing procedure.But in prior art, also there is no the rational in infrastructure technical scheme that can complete this target.
Such as, in existing open file, the Chinese patent literature having Publication No. 202291027U, publication date to be 2012-07-04, disclose a kind of flanging die, including upper mold and the lower mold that matches with this upper mold, ejecting mechanism it is provided with in lower mold, this ejecting mechanism includes: the pilot hole offered along matched moulds direction in lower mold, along the axially arranged spring of pilot hole in this pilot hole, a part for this spring is protruding from pilot hole, further, pilot hole is formed with restriction spring away from upper mold side to the limiting section of motion.This technical scheme is disadvantageous in that, the part after this die flanging needs to increase trimming and carries out shaping, and this needs additionally to arrange shaping mould and supporting forcing press, increases cost.
Utility model content
For solving to need to separately design flanging die and shaping mould when existing cold-punched mould steel makes, Design of Dies and the high problem of cost of manufacture, this utility model provides a kind of flanging and restriking cold-punching mould Self-resetting wedge structure that can simultaneously complete overturning process and trimming.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of flanging and restriking cold-punching mould Self-resetting wedge structure, including upper bolster, die shoe be arranged on the dressing stick below upper bolster, the lower surface of upper bolster is provided with driving arm, drives the lower surface of arm to be provided with the first cammed surface of inclination；The lower surface of dressing stick is provided with the second cammed surface of inclination, the upper nitrogen cylinder promoting dressing stick to move in the horizontal direction it is provided with between dressing stick and upper bolster, die shoe is arranged over movable slider, is provided with the lower nitrogen cylinder promoting movable slider to move in the horizontal direction between movable slider and die shoe；Have on movable slider and determine shaping surface, dressing stick has and determines the dynamic shaping surface that shaping surface matches.This utility model may be installed on flange die, so, while upper bolster has depressed parts flanged-edge, driving arm moves downward, and by first cammed surface the first slide guide inclined-plane transmitting movement to movable slider, is promoted to the left by movable slider, movable slider to determine shaping close towards dressing stick, until driving arm to disengage with the inclined-plane of movable slider, movable slider is blocked by the lower end driving arm, and movable slider cannot be retracted by lower nitrogen cylinder；Then upper bolster continues to move downward, and dressing stick is descending along the second slide guide inclined-plane of movable slider by the second cammed surface thereon, so that the dynamic shaping surface on dressing stick moves closer to determine shaping surface on movable slider, part is carried out shaping；After shaping action completes, dressing stick and movable slider are returned to initial position respectively under the effect of upper nitrogen cylinder and lower nitrogen cylinder, are ready for action next time.
As preferably, the upper surface of dressing stick has two-stage hierarchic structure, the hypomere driving arm is fitted in the right side of the first ladder of movable slider, the right part of the first ladder upper surface has the first slide guide inclined-plane equal with the first cammed surface inclination angle, and the right part of the upper surface of the second ladder of movable slider is provided with the second slide guide inclined-plane matched with the second cammed surface.
As preferably, the first cammed surface is 45 degree to 60 degree with the angle of horizontal plane, and the second cammed surface is 45 degree to 60 degree with the angle of horizontal plane.The angle of 45 degree to 60 degree make to drive arm and the opposing force of movable slider, dressing stick and movable slider opposing force in the horizontal direction and the component size to fit of vertical direction.
As preferably, upper bolster is provided with safety screen, and the side of dressing stick is provided with the upper rail matched with upper safety screen；Die shoe is provided with lower safety screen, and the side of movable slider is provided with the lower guide channel matched with lower safety screen.Coordinated by the upper rail on upper safety screen and dressing stick, dressing stick held stationary during translation can be made, and do not fall out predetermined tracks；Coordinated by the lower guide channel on lower safety screen and movable slider, movable slider held stationary during translation can be made, and do not fall out predetermined tracks.
As preferably, the side of dressing stick is provided with cushion pad, and the side of movable slider is provided with lower cushion pad, and upper cushion pad is all rubber with the material of lower cushion pad.During upper mold moves to after bottom dead center backhaul; due to cancelling of impressed pressure; upper nitrogen cylinder and lower nitrogen cylinder can produce bigger thrust to movable slider and dressing stick; movable slider and dressing stick with bigger velocity collision to the structure closed on, can set up the upper cushion pad of quality of rubber materials or lower cushion pad can protect movable slider and dressing stick will not damage with adjacent structure.
As preferably, dressing stick is arranged over slide plate, is provided with lower slide plate, upper slide plate and lower slide plate and is respectively provided with smooth abrasive end face below movable slider.During mold work, movable slider and dressing stick can translate, increase smooth upper slide plate and lower slide plate can reduce movable slider and the dressing stick frictional force in translation motion, the motion making movable slider and dressing stick is more smooth and easy, reduce movable slider and the abrasion of dressing stick, increase the mold use life-span.
As preferably, the longitudinal section driving arm is " 7 " font.
The beneficial effects of the utility model are: can complete the flanging and restriking cold-punching mould Self-resetting wedge structure of overturning process and trimming simultaneously, compared with separately designing the scheme making flanging die and shaping mould, decrease number of molds and the quantity of corresponding pressure machine, thus save the manufacturing procedure being designed and manufactured as this, shortening part, improve production efficiency.
