Also comprise guiding mechanism and real-time detecting system; Described guiding mechanism comprises outer guiding post and outer bush, outer bush and punch retainer interference fit, outer guiding post and die block interference fit, and outer guiding post and outer bush, by the ball interference fits of guide pin bushing inside, can slide up and down;
Described real-time detecting system comprises ccd sensor, lighting source, telecentric lens, image pick-up card, computer; Lighting source and telecentric lens and ccd sensor are arranged in die hole; Described image pick-up card is arranged in computer, and described computer is connected with described ccd sensor long distance wireless with image pick-up card; Described lighting source is arranged on beats boom end, and described ccd sensor and telecentric lens are arranged on the position of die hole between upper bolster and upper mounted plate.
Further: described rubber mat adopts polyurethane rubber to make, and rubber mat is socketed on pull bar surface.
The accurate Drawing Die of one described in the utility model, it has the following advantages:
1, the utility model is provided with real-time detecting system, can real-time monitored drawing process, by changing the telecentric lens of different focal, can observe plate macroscopic appearance, can observe plate microphenomenon again; The utility model utilizes guiding mechanism that mould is led accurately, realizes steady reliable mobile;
2, the utility model is provided with holding pad, and when drawing and forming, upper bolster is descending with forcing press, holding pad is under the action of the spring for workpiece provides enough pressure-plate-forces, avoid surface of the work wrinkling, ensure that the surface quality of workpiece, reduce percent defective, after drawing completes, make bar to reset under the effect of rubber blanket, workpiece is released in die hole, avoids workpiece and be stuck in the phenomenon can not taken out in die hole, improve operating efficiency, extend the mold use life-span; Annular boss on the utility model stripper further increases pressure-plate-force, improves workpiece quality, very convenient and practical;
3, stripper of the present utility model is connected with roof movement by unloading bolt, is socketed with discharging spring outside unloading bolt, is provided with multilayer rubber cushion between top board and supporting plate; When drawing starts, discharging spring stress compresses, and the rubber blanket under top board also starts compression, when after the descending contact push rod of drawing die, discharging spring is no longer compressed, pressure-pad-force also can not change, reach pressure-pad-force reach certain numerical value after substantially constant effect, keep constant, avoid the phenomenon that pressure-pad-force increases with the increase of stroke, greatly reduce the possibility that drawing part critical section breaks, improve product surface quality, reduce percent defective.Rubber blanket adopt polyurethane rubber make, elasticity and wearability good, long service life.Some rubber blankets are separated by iron plate, can effectively prevent strength from discharging, improve pressure-pad-force, have good practicality;
4, the utility model drawing punch is connected with die shoe by bottom plate, is provided with lower bolster between drawing punch and die shoe; Drawing die is connected with upper bolster by upper mounted plate, is provided with upper padding plate between drawing die and upper bolster; Drawing die of the present utility model and drawing punch are all be connected with die holder with backing plate by fixed head, this structure can provide buffering effect by the cushioning effect of backing plate in whole drawing process, be unlikely to allow pressure-plate-force increase suddenly or to suddenly disappear, further ensure the even of pressure-plate-force; The effect of this fixed head and backing plate can also realize the convenient adjustment of the relative distance of drawing die and drawing punch, adds the scope of application of mould;
5, the utility model rubber blanket is by nut encapsulates in upper bolster, is convenient for changing; The utility model, drawing punch is up-small and down-big notch cuttype, in therefore can being connected with die shoe by bottom plate reliably bottom it, ensure that the stability of whole drawing process.
