Operation principle of the present invention and process are such.
1, the mould course of action of unblanking:
As Fig. 1,2,6,7, shown in 8, drive motors 37 work, it drives simultaneously, following reduction box assembly 37,38 synchronization actions, power transmission shaft 13 and lower drive shaft 18 rotate synchronously in the event, overhead cam 9 is with last power transmission shaft 03 rotation, because the variation of overhead cam 9 curves, the pretension elastic force that overhead cam 9 driving cope match-plate patterns 4 overcome maintenance spring 8 moves down, at present cam 14 rotates with lower drive shaft 18 together, owing to the variation of cam 14 curves down, the pretension elastic force that following cam 14 driving lower bolsters 6 overcome maintenance spring 8 moves up, so on, lower bolster 4, the 6th, move toward one another has realized the locked mode process simultaneously.
When last power transmission shaft 13 and further rotation synchronously of lower drive shaft 18, overhead cam 9 continues with last power transmission shaft 13 rotations, overhead cam 9 curves further change, cope match-plate pattern 4 can move up under the pretension elastic force effect that keeps spring 8 and reset, with lower drive shaft 18 rotations, because cam 14 curves further change down, lower bolster 6 can move down under the pretension elastic force effect of maintenance spring 8 and reset with cam 14 continuation at present, so upper and lower template the 4, the 6th, counter motion has simultaneously realized the die sinking process.
2, feeding and pitch adjustment process:
Shown in Fig. 3,6,7,8, when the mold process of unblanking carries out, feeding pitch cam 22 is with lower drive shaft 18 rotations, because the variation of feeding pitch cam 22 curves, under the effect of back-moving spring 26, guide rod 20 is made reciprocal move left and right simultaneously, and guide rod 20 just drives fork 14 and is a spot wobble with fulcrum location-plate 25, and fork 24 drives pull bar 23 and promotes second plate, 62 relative first plates 61 and laterally move back and forth, to realize the purpose of progressively feeding.This feeding process is carried out simultaneously with the mold process of unblanking, and the mold process of once unblanking is finished a feeding.
When adjusting pitch, shown in Fig. 1,3, drive 28 actions of worm and gear transmission component, fulcrum location-plate 25 can be along with moving up and down, the rotating fulcrum of fork 24 changes, can realize the change of fork 24 amplitudes of fluctuation, making second plate 62, horizontal mobile range is corresponding changes, and then realizes the adjustment to the product feeding pitch.
3, the adjustment of die height:
As shown in Figure 4, during adjustment pressure oil connected part hydraulic cylinder 31 epicoeles, epirelief wheel seat 10 is mentioned with last machine plate 1, while drive motors 36, last reduction box assembly 37 is also mentioned with last machine plate, scalable connecting axle 39 is stretched, gapped between last machine plate 1 and the stop nut 30, subsequently, motor 33 drives stop nut 30 rotations under travelling gear 34 and chain 32 effects, after having adjusted height parameter, by the reversal valve in the oil path control system 35 pressure oil is switched hydraulic cylinder 31 cavity of resorptions, epirelief wheel seat 10 is moved downward with last machine plate 1, last machine plate 1 and stop nut 30 tight pressings, and maintenance oil pressure, thereby the accurate adjustment of realization shut height.Adjust the pressure of cope match-plate pattern 4 by hydraulic cylinder 31,, avoid mold damage and equipment so can prevent the generation of upper and lower template 4,6 overloads.
