Description
Technical field
The utility model relates to a kind of diel, especially relates to the diel that a kind of punching out has protruding luxuriant part.
Background technology
More existing punching parts have protruding bud, as illustrated in fig. 1 and 2, produce the diel of this class part, mainly are at the mould that has device for discharging.The diel of traditional structure as shown in Figure 3 comprises die shoe 1, spring 2, push rod 3, lower bolster 4, guidance set 5, concave template 6, stripper 7, towards pin 8, fixed head 9, upper padding plate 10, discharging spring 11 and upper bolster 12.Such mould acts directly on spring 2 on the push rod 3, some in addition do not have spring 2 and push rod 3.Its course of work is, the mould closure touches punching parts towards pin 8 and begins to dash bud, and it should overcome towards luxuriant resistance, overcomes the thrust of push rod 3 again.When die sinking, push rod 3 is released protruding bud.Its weak point is: when push rod 3 thrusts too hour, protruding bud can't be released; When push rod 3 thrusts are too big, will become very difficult towards bud.Thrust to be adjusted to suitable strength, need repetition test.Owing to the variation of situations such as wearing and tearing, lubricated, also need a large amount of maintenance works aborning.When protruding bud height h is too high (h 〉=2t/3, t are part thickness), particularly evident, even the situation of the maximum resistance that the required minimum thrust of protruding bud＞dash bud can overcome may appear ejecting, can't finish smoothly towards bud like this.
Summary of the invention
The purpose of this utility model is to dash the bud difficulty, need deficiencies such as repetition test and a large amount of maintenance works at existing diel, provide a kind of punching parts that significantly improves towards luxuriant manufacturability, the protruding luxuriant part that is difficult to moulding can be produced smoothly, and the diel of the protruding luxuriant part of punching out band of the debugging of minimizing mould and maintenance.
For this reason, the technical solution adopted in the utility model is on the basis of above-mentioned mould, and ejecting structure is improved.Increase transmission rod and pushing block, rationally set the pushing block height.
The utility model is provided with die shoe, spring, transmission rod, lower bolster, pushing block, push rod, concave template, towards luxuriant mold insert, stripper, fixed head, towards pin, upper padding plate, upper bolster, discharging spring, guide pin bushing, guide pillar.
Die shoe is positioned at mold bottom, is lower bolster and concave template successively above the die shoe, and lower bolster and concave template and die shoe are fixed together by screw, constitutes the part of the lower die; Mould topmost is a upper bolster, is upper padding plate and fixed head in its lower section successively, and upper padding plate and fixed head and upper bolster are fixed together by screw, constitutes the part of the upper die; The discharging spring is located on the upper bolster, and the pressure of discharging spring passes to stripper by screw and sleeve pipe, makes the punching parts that stripper can compress needs processing; Stripper is positioned in the middle of the mould, and stripper, part of the upper die and part of the lower die are by guide pillars and bushes location, connection; Be fixed in the fixed head towards pin, and pass stripper and contact with punching parts; Pushing block, push rod and be located in the concave template towards luxuriant mold insert, pushing block is positioned at below luxuriant mold insert, and push rod is positioned at pushing block and in the middle of luxuriant mold insert; Transmission rod is located in the lower bolster, contacts with pushing block; Spring is located at the transmission rod below, and spring is contained in the die shoe.
The utility model improves ejecting structure on the basis of original diel.Increase transmission rod and pushing block, by rational setting pushing block height, when dashing bud, stripper is depressed pushing block, makes push rod be in free state, dashes the resistance that bud just is not subjected to spring towards pin like this; After withdrawing from punching parts towards pin, stripper leaves pushing block, and spring strength just acts on the push rod, and push rod ejects protruding bud.So both can set ejecting force very greatly, and guarantee protruding bud is ejected, and can make again when pin dashes bud, not to be subjected to ejecting resistance, be beneficial to towards bud and finish, when especially highly h is very high for protruding bud (h 〉=2t/3, t are part thickness), during height tolerance very little (below ± 0.03).Can realize production steady in a long-term.

The specific embodiment
Following examples will be further described the utility model in conjunction with the accompanying drawings.
Shown in Fig. 4-7, the utility model on existing diel basis (referring to Fig. 1 and 2) has been done improvement, and the utility model is provided with die shoe 1, spring 2, transmission rod 3, lower bolster 4, pushing block 5, push rod 6, concave template 7, towards luxuriant mold insert 8, guide pin bushing 9, stripper 10, fixed head 11, towards pin 12, upper padding plate 13, sleeve pipe 14, upper bolster 15, discharging spring 16, guide pillar 17.
Be lower bolster 4 and concave template 7 successively above the lower mould seat 1, screw is fixed together them, constitutes the part of the lower die; Mould topmost is a upper bolster 15, is upper padding plate 13 and fixed head 11 in its lower section successively, also is to be fixed together by screw, constitutes the part of the upper die; Be provided with discharging spring 16 on upper bolster 15, the pressure of spring 16 passes to stripper 10 by screw and sleeve pipe 14, makes the punching parts that stripper 10 compresses needs processing; Stripper 10 is positioned in the middle of the mould, and stripper 10, part of the upper die and part of the lower die are located, linked up by guide pillar 17 and guide pin bushing 9 again.
Towards luxuriant part-structure be: dash bud and be fixed in the fixed head 11, and pass stripper 10, touch punching parts towards pin 12; Set pushing block 5, push rod 6 and towards luxuriant mold insert 8, pushing block 5 is positioned at below luxuriant mold insert 8 in concave template 7, push rod 6 is positioned at pushing block 5 and in the middle of luxuriant mold insert 8; Transmission rod 3 contacts with pushing block 5 in lower bolster 4; Be spring 2 below the transmission rod 3, spring 2 is contained in the die shoe 1.
The process that mould dashes bud is: the upper mould part is down moved from top dead-centre, when stripper 10 touches punching parts, touch pushing block 5, continuation decline along with upper bolster 15, stripper 10 is pressed onto punching parts and pushing block 5 upper surface of concave template 7 simultaneously, because pushing block 5 is depressed, push rod 6 is in free state; Upper bolster 15 descends again, and stripper 10 no longer moves, and discharging spring 16 is further compressed, continue to descend towards pin 12, touch punching parts and begin to dash bud, be closed into bottom dead centre up to mould and finish towards bud, dash the resistance that bud only is subjected to punching parts itself like this, and be not subjected to push rod 6 top power.Upper bolster 15 begins to rise afterwards, withdraws from punching parts towards pin 12, and push rod 6 still is in free state.Along with the continuation of upper bolster 15 is risen, stripper 10 begins to move upward and leaves concave template 7, and at this moment spring 2 up pushes away transmission rod 3, pushing block 5 and push rod 6 together, and push rod 6 releases protruding bud towards luxuriant mold insert 8.Upper bolster is got back to after top dead center, and a punching stroke finishes.
Figure 7 shows that towards luxuriant mold insert figure bottom slot is in order to step down for pushing block 5.
