Fig. 2 is existing punching die organigram.
Fig. 3 is a piercing and flanging composite die free state sketch map of the present invention.
Fig. 4 is a piercing and flanging composite die working state schematic representation of the present invention.
Among the figure: 1. upper bolster, 2. rocking bar drive block, 3. holder, 4. rocking bar, 5. rocker shaft, 6. bolt, 7. die shoe, 8. limited block, 9. guide pad, 10. lower die cutter piece, 11. drifts, 12. drift holders, 13. holding pads, 14. flange cutter pieces, 15. flange cutter piece drive blocks, 110. flange lower die cutter pieces, 113. flange holding pads.
The specific embodiment
As shown in Figure 1; Be the existing mould that plate is carried out the upper overturning operation, flange cutter piece is fixed on the die shoe, and flange holding pad 113 is located on the die shoe through spring; Between upper bolster and flange holding pad 113, be provided with flange lower die cutter piece 110; During work, upper bolster drives the flange holding pad and moves downward, and handles thereby make flange cutter piece carry out upper overturning to plate.As shown in Figure 2, for having the mould that plate is carried out punch operation now, drift is fixed on the upper bolster through the drift fixed head; Holding pad is located on the upper bolster, during work, earlier plate is positioned; Upper bolster moves downward, and drives drift and moves downward, and holding pad is pushed down plate; Drift passes plate, accomplishes processing.
When on same product, carrying out flange and punching through above-mentioned mould; Usually need two molds to accomplish; Significantly increased the manufacturing cost of the production cost and the mould of product, because divide preface production, twice location must reduce precision and the efficient that product is produced simultaneously.For addressing this problem, a kind of piercing and flanging composite die is provided, can be implemented in and accomplish flange and punch work on the same product simultaneously.
As shown in Figure 3; A kind of piercing and flanging composite die; Comprise upper bolster 1 and die shoe 7, described upper bolster 1 is provided with holding pad 13 and drift 11, and drift 11 is fixed on the upper bolster 1 through drift holder 12; On die shoe 7, be provided with the lower die cutter piece 10 suitable, and on the die shoe below the lower die cutter piece, be provided with the material-dropping hole of plate with drift 11.For realizing goal of the invention; On die shoe 7, be set with holder 3 through bolt 6; Between holder 3 and die shoe 7, be provided with flange cutter piece drive block 15 moving up and down; And on holder and die shoe, be equipped with the guide pad 9 that flange cutter piece drive block is moved up and down guiding; On flange cutter piece drive block 15, be provided with flange cutter piece 14, on described holder, be provided with and drive the endplay device that flange cutter piece drive block moves up and down, its endplay device comprises rocker shaft 5 that is fixed on the holder 3 and the rocking bar 4 that is hinged with rocker shaft; Described rocking bar 4 one ends are corresponding with rocking bar drive block 2 on being located at upper bolster 1, and described rocking bar 4 other ends are located at flange cutter piece drive block 15 belows.In order to guarantee that mould has better duty, carry out spacing limited block 8 in the rocking bar end that is provided with on the described die shoe 7 below the flange cutter piece drive block, be provided with bulge-structure above the rocking bar end below described flange cutter piece drive block.
In order to switch to the duty of only carrying out flange or punching according to needs of production, described drift holder is detachable on upper bolster, and described rocking bar drive block is detachable on upper bolster.
As shown in Figure 4, during use, upper bolster 1 moves downward, and drives drift 11 and moves downward, and holding pad 13 is pushed down plate, and drift 11 is corresponding with lower die cutter piece 10, and drift passes plate and accomplishes punch work; When upper bolster continues to move downwards, drive rocking bar drive block 2 and move downward, rocking bar drive block 2 and rocking bar one end in contact; Drive rocking bar 4 and be rotated counterclockwise around rocker shaft 5, rocking bar 4 other ends contact with flange cutter piece drive block 15 rigidity, and drive flange cutter piece drive block 15 is done and moved up; Flange cutter piece drive block 15 drives flange cutter piece 14 and moves upward; Because the applying of flange cutter piece 14 and holding pad 13 direct shapes promptly is to accomplish the flange work of being scheduled to, successful solution in one procedure, accomplish the difficult problem of upper overturning and trimming and piercing die work simultaneously; Open up the mentality of designing of flange body, reduced the cost input of mould.Simultaneously, when not needing flange, can pull down rocking bar drive block 2, convenient and simple realization flange and the switching of not turning over; When not needing punching, can pull down drift 11 and drift holder 12, the convenient and simple realization punching and the switching of not punching.
In the present invention, can on same product, accomplish flange and punch work simultaneously, only need one-time positioning to realize, make the production precision of product and efficient that very big lifting all arranged through this mould; Because this composite die can only carry out flange or punch work state according to realizing that the needs of producing switch to, make this composite die have purposes widely again, reduce manufacturing cost; And this composite die is reasonable in design, simple in structure, it is little to take up room.
