Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Refer to Fig. 2 to Fig. 6 and show an embodiment of the present invention better embodiment for the pressing and bending mould of display backplane.
As shown in Fig. 2-Fig. 6, the present embodiment is a kind of pressing and bending mould for display backplane, and this pressing and bending mould includes upper bolster 1, upper de-plate 6 and lower bolster 5 from top to bottom successively, is connected to several elastic component 7 between upper bolster 1 and upper de-plate 6; Upper de-plate 6 is installed with the downwardly projecting curved punching pin of the left folding in its lower surface 601, the curved punching pin of right folding 602 and rear bending punching pin 603; The right folding that the upper surface concave downward of lower bolster 5 has the left folding matched with the curved punching pin of left folding 601 to bend into groove 501 and the curved punching pin of right folding 602 matches bend into groove 502 and the rear bending matched with rear bending punching pin 603 enters groove 503.
When the bending part on three limits of the display backplane shown in Fig. 1 is carried out pressing and bending, as shown in Figure 2, upper de-plate 6 moves downward until conflicting and arriving display backplane workpiece, upper de-plate 6 continues to move downward, the downward punching press display backplane workpiece of the curved punching pin of left folding 601 bend in groove 501 to left folding, the downward punching press display backplane workpiece of the curved punching pin of right folding 602 bend in groove 502 to right folding, the rear downward punching press display backplane workpiece of bending punching pin 603 to rear bending enters in groove 503, namely three the bending punching pines downward punching press display backplane workpiece simultaneously on upper de-plate 6 enters in groove to three corresponding bendings on lower bolster 5, punching press pressing and bending simultaneously generates the bending part on three limits of display backplane as shown in Figure 1, significantly improve the working (machining) efficiency of pressing and bending.When, after the bending part pressing and bending molding on three limits of display backplane, successfully display backplane being departed under the effect of elastic component 7 de-plate 6.
Display backplane workpiece is being carried out in pressing and bending process, in order to accurately display backplane workpiece is limited on fixing position, to improve pressing and bending precision, as shown in Figure 2, Figure 5 and Figure 6, the limited location projection 504 protruding upward in the upper surface of lower bolster 5. The protrusion height of spacing preiection 504 is not more than the thickness of display backplane workpiece, to avoid display backplane workpiece punching press not in place, affects the pressing and bending precision of display backplane.
Concrete, as shown in Figure 2, Figure 5 and Figure 6, the left folding on lower bolster 5 bend into groove 501 and right folding bend into groove 502 and is C-channel and be arranged in parallel; Rear bending enters groove 503 for L-shaped groove, and rear bending enters groove 503 and left folding bend into groove 501, right folding bend into groove 502 and connects respectively and be vertically arranged.
Additionally, as in figure 2 it is shown, be installed with the die shoe 3 for supporting lower bolster 5 in the lower section of lower bolster 5.
In order to make three bending punching pines on upper de-plate 6 enter the more accurate of slot fit with three bendings on lower bolster 5, improve the pressing and bending machining accuracy of display backplane, as shown in Figure 2, upper bolster 1 is connected with several guide pillar 2, die shoe 3 is provided with several pilot hole 301 matched with guide pillar 2 or guide pin bushing, so that upper de-plate 6 accurately to be led.
Continue referring to Fig. 2, upper bolster 1 and on be connected with the train wheel bridge 8 for plate 6 active force de-on bearing between de-plate 6, it is connected with upper padding plate 9 between upper bolster 1 and train wheel bridge 8, makes upper bolster 1 produce depressed deformation to avoid the active force of train wheel bridge 8 to be applied directly on upper bolster 1.
In the present embodiment, as in figure 2 it is shown, the upper end of elastic component 7 is affixed with upper bolster 1, the lower end of elastic component 7 is affixed with upper de-plate 6, and elastic component 7 sequentially passes through upper bolster 1, upper padding plate 9 and train wheel bridge 8 from top to bottom.
Die shoe 3 is made to produce depressed deformation for avoiding the active force of lower bolster 5 to be applied directly on die shoe 3, as in figure 2 it is shown, be connected with lower bolster 4 between die shoe 3 and lower bolster 5.
Obviously, the above embodiment of the present invention is only used to the clear example of the present invention that illustrates, and is not the restriction to embodiments of the present invention. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also cannot all of embodiment be given exhaustive.
