Abstract

The utility model provides an anti-wrinkling structure for drawing and forming. A drawing die comprises an upper female die and a lower male die both used for the drawing of plates, as well as a blank holder arranged on the lower male die in a sleeving manner, wherein a groove is formed in the blank holder; protruded ribs corresponding to the groove are arranged on the upper female die and form material-stopping ribs and wrinkling-absorbing ribs together with the grooves; the material stopping rib is circular-shaped; multiple wrinkling-absorbing ribs are uniformly arranged in the circumferential direction of the material stopping rib. According to the utility model, during a drawing process, the upper female die is lowered so as to press the plates on the blank holder, and the wrinkling-absorbing ribs arranged between the upper female die and the blank holder can press the wrinkled plates into the shapes of the wrinkling-absorbing ribs, the large area winkling of the pressed plates is avoided, the upper female die and the blank holder are fit completely, the wrinkling of the plates on the blank holder during the drawing is eliminated, and the instability of the drawing of the plates is avoided.

Description

The anti-corrugated structures of drawing modeling
Technical field
The utility model relates to plate cladding element punching field, relates in particular to a kind of anti-corrugated structures for deep drawing of sheet moulding, realizes the laminating completely of upper cavity die and blank holder, has avoided the unstability of deep drawing of sheet.
Background technology
Sheet Metal Forming Technology is widely used in auto manufacturing in recent years, and the many coverings in vehicle and inner plate all utilize mould punching to be shaped.Conventionally, complicated part generally all needs just can complete shaping through drawing modeling, deburring, flange, shaping etc. multistep operation.But some part is due to the restriction of shape, structure in actual production, after draw forming operation, product surface just there will be undesirable condition, therefore will cause end product quality to reduce, and even occurs waste product.
For example aluminium sheet, because its density is little, anticorrosive property good, collision energy-absorbing high, is more and more widely used on automobile panel.But also, because its insufficient formability, deburring chip are serious, springback capacity is difficult to control, high in cost of production feature, there is a lot of difficult points in exploitation aluminium sheet cladding member mold.The stability that wherein aluminium sheet drawing die is shaped is extremely important, and in the time that aluminium sheet draw forming process convex mould profile is evagination state, aluminium sheet material is easy on the blank holder of relevant position wrinkling, causes aluminium sheet draw forming unstable.
Utility model content
Technical problem to be solved in the utility model is exactly for current drawing modeling above shortcomings, provides a kind of drawing modeling anti-corrugated structures, for solving the problems of the prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of drawing modeling anti-corrugated structures, drawing die comprises for the upper cavity die of deep drawing of sheet, lower punch and is set in the blank holder on described lower punch, described blank holder is provided with groove, described upper cavity die is provided with the convex tendon corresponding with described groove and jointly forms resistance material muscle and inhale wrinkle muscle, described resistance material muscle is annular, is circumferentially evenly provided with many inhales wrinkle muscle along described resistance material muscle.
Further, described groove is circular groove.
Further, described suction wrinkle muscle inner end is provided with smooth transition surface.
Further, interval 100mm between adjacent suction wrinkle muscle.
By above technical scheme, the utility model has following technique effect compared to prior art: in drawing process, upper cavity die declines, plate is pressed on blank holder, inhale wrinkle muscle because be provided with between upper cavity die and blank holder, Xi Zhou influential point of tendons is pressed into fretful plate in the shape of inhaling wrinkle muscle, also just avoided the wrinkling situation in binder surface large area, upper cavity die and blank holder are fitted completely like this, eliminate when deep drawing of sheet wrinklingly on blank holder, avoided the unstability of deep drawing of sheet.

Element numbers explanation:
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1 to Fig. 5.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
The utility model provides a kind of drawing modeling anti-corrugated structures, drawing die comprises for the upper cavity die 3 of deep drawing of sheet, lower punch 6 and is set in shown in the blank holder 4(Fig. 1 on lower punch 6), blank holder 4 is provided with groove, and upper cavity die 3 is provided with that the convex tendon corresponding with groove is configured to the resistance material muscle 1 of drawing resistance material jointly and with solving the wrinkling suction wrinkle muscle 2 of plate on drawing binder surface.Resistance material muscle 1 is annular, is circumferentially evenly provided with many inhales shown in wrinkle muscle 2(Fig. 2 and Fig. 3 along resistance material muscle 1).
In the utility model, suction muscle has 5, and interval 100mm between adjacent suction wrinkle muscle, is normal direction plumbness with resistance material muscle.The groove of every suction muscle is circular groove structure (shown in Fig. 4), inhales wrinkle muscle inner end and is provided with smooth transition surface (shown in Fig. 5).
For example, in the time that automobile aluminium sheet is carried out to drawing, first upper cavity die 3 declines, and plate 5 is pressed on blank holder 4, and due to the shaping inhomogeneities of plate, plate there will be divergent shape ripple in the outside of resistance material muscle 1, and this ripple is substantially vertical with resistance material muscle 1.Because the upper cavity die 3 that exists of this ripple is difficult to fit with blank holder 4, this has just caused drawing unstable.Between blank holder 4 and upper cavity die 3, arranging after suction wrinkle muscle 2, inhaling wrinkle muscle 2 can be pressed into fretful plate 5 in the shape of inhaling wrinkle muscle, also just avoided the wrinkling situation in binder surface large area, upper cavity die 3 is fitted completely with blank holder 4, has avoided the unstability of deep drawing of sheet.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
