Abstract
Conical part Drawing Die with unsettled sidewall clamping device is used for sheet forming field, mainly solves conical part unsettled wall deformation district in drawing process and to crease easily problem.Its technical scheme is, nitrogen spring is positioned at the upper bolster of Drawing Die and the groove of die block, pressed on ring is between slab and upper nitrogen spring, lower ring is between slab and lower nitrogen spring, the planar end surface of upper ring and a lower ring and nitrogen spring ejector pin contact, the arc surface of upper ring and a lower ring contacts with unsettled sidewall region slab.In forming process, after spring pressurized, power is passed to the distortion slab of unsettled sidewall region by annulus, thus clamping action is produced to slab, prevent wrinkling.The utility model compensate for conical part unsettled sidewall region slab in drawing process and is in the deficiency of the easy Instability wrinkling of vacant state, can improve forming limit.
Description
Technical field
The utility model relates to sheet material forming field, is specifically applied to the Drawing Die that conical part is shaped.
Background technology
To conical part drawing and forming, easily wrinkling at two deformed regions, one is flange, and two is unsettled sidewall region.In forming process, blank holder is set and can prevents the wrinkling of flange, but the shape of unsettled sidewall region slab is constantly change in deformation process, not with punch, die and other feature contacts, be in free state, be easy to wrinkling under hoop pressure stress effect.Adopting traditional cupping tool structure, can only push down the slab of flange, easily there is wrinkling unstability in middle unsettled sidewall region, and wrinkling rear slab forming process can not proceed.
Summary of the invention
The utility model object is that when preventing conical part to be shaped, unsettled sidewall region is wrinkling, overcomes the deficiency of existing mold in suppression is wrinkling, thus improves conical part forming limit.
With the conical part Drawing Die of unsettled sidewall clamping device, it comprises nitrogen spring, punch retainer (1), push rod (13), blank holder (3), die (4), upper bolster (7), pressed on ring (5), lower ring (11) and punch (12), it is characterized in that: upper nitrogen spring is positioned at cope match-plate pattern groove, pressed on ring is between upper nitrogen spring and slab, the ejector pin contact of pressed on ring planar end surface and upper nitrogen spring, pressed on ring arc surface contacts with unsettled sidewall region slab upper surface; Lower nitrogen spring is positioned at punch retainer groove, and lower ring is between slab and lower nitrogen spring, and the ejector pin contact of lower ring planar end surface and lower nitrogen spring, lower ring arc surface contacts with unsettled sidewall region slab lower surface.
The technical scheme in the invention for solving the technical problem is: two annulus of upper and lower both sides, the unsettled sidewall region of slab, in drawing process, move with distortion slab, and the pressure of nitrogen spring is applied on slab, thus reach the wrinkling object of suppression.
Compared with prior art, the utility model has following beneficial effect: 1. can prevent the wrinkling unstability in the unsettled sidewall region of conical parts, improves the forming limit of conical parts; 2. nitrogen spring can provide constant pressure; 3. cost is low, and feasibility is high.
Accompanying drawing explanation
Figure is the schematic diagram of the utility model die device;
In figure: 1-punch retainer, 2-unloading bolt, 3-blank holder, 4-die, 5-pressed on ring, 6-screw, 7-upper bolster, the upper nitrogen spring of 8-, 9-cushion block, 10-slab, ring under 11-, 12-punch, 13-push rod, nitrogen spring under 14-, 15-screw.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, this flange fixing installation concrete structure is: punch 12 is fixed on punch retainer 1 by screw 15, unloading bolt 2 is connected with blank holder 3, upper bolster 7, cushion block 9 are connected with die 4 by screw 6, lower nitrogen spring 14 is positioned over punch retainer 1 groove, upper nitrogen spring 8 is positioned between upper bolster 7 and pressed on ring 5, and the position that pressed on ring 5 and lower ring 11 contact with slab 10 is circular shape, and push rod 13 provides pressure-pad-force.
In drawing process, upper bolster 7 moves downward under external force, and slab 10 flange compresses by die 4 and blank holder 3, carries out drawing to slab 10, and pressed on ring 5 moves with distortion slab 10 with lower ring 11.Upper nitrogen spring 8 and lower nitrogen spring 14 pressurized, piston retraction, and transfer the pressure to slab 10 by pressed on ring 5 and lower ring 11.
The utility model respectively increases an annulus by the both sides of shaping slab, and in drawing process, upper ring and a lower ring applies pressure to unsettled sidewall region slab, and conical part unsettled sidewall region in drawing process can be prevented wrinkling, improves forming limit.
The utility model includes but not limited to present embodiment, and every principle is identical with mentality of designing and the utility model, or the simple substitute to the design, all falls within protection domain of the present utility model.
