Description

One kind is based on spring discharging carrier bar upside-down mounting composite die
Technical field
The utility model is related to one kind and is based on spring discharging carrier bar upside-down mounting composite die, belongs to diel field, mainly For chain sheet punching, blanking.
Background technology
Motorcycle, the chain link of bicycle are made up of " rolling ring+carrier bar+chain pin (chain rivet) " three parts in life, chain It is made up of the chain link slight one by one of this spline structure.Its intermediate plate is frequently with the multiple operation such as punching, blanking punching press side Formula is obtained.But process is more, production cost is higher, and precision is also lower.In order to reduce the cost and improve precision, practice production In invented a kind of upside-down mounting composite die, a procedure can complete punching, the process of blanking.
The content of the invention
In view of the above-mentioned problems of the prior art, a kind of production process of the utility model offer is few, designs and be manufactured into This relatively low upside-down mounting composite die.
The technical solution of the utility model is:One kind is based on spring discharging carrier bar upside-down mounting composite die, including knockout rod, mould Handle, stop pin, straight pin, upper bolster, upper die plate, punch retainer, pushing block fixed plate, cavity plate, stripper, spring, convex-concave Mould fixed plate, lower mold backing plate, die shoe, unloading bolt, punch-die, screw, alignment pin, guide pillar, guide pin bushing, pushing block, punch-pin, die shank Be interference fitted in upper bolster, knockout rod through punch retainer, upper die plate, die shank, straight pin through upper bolster, on Die-cushion plate, punch retainer, pushing block fixed plate and cavity plate, alignment pin through upper bolster, upper die plate, punch retainer, on Die holder, upper die plate, punch retainer, pushing block fixed plate and cavity plate mode connects for screw, punch-pin are placed in upper die plate and consolidated with punch-pin Between fixed board, guide pin bushing is interference fitted with upper bolster, and pushing block is placed between punch retainer and pushing block fixed plate;Stripper, spring, Punch-die fixed plate is connected with lower mold backing plate with unloading bolt, punch-die fixed plate, lower mold backing plate and lower seat mould mode connects for screw Fixed, punch-die is fixed on lower mold backing plate with mode connects for screw, and guide pillar is in interference fit with die shoe.
The stripper, punch-die fixed plate are machined with 4 circular grooves, for spring positioning.
Carrier bar upside-down mounting composite die described in the utility model is easy to use, and a procedure can complete punching with falling Material, is designed low with manufacturing cost.
Brief description of the drawings
Fig. 1 is that the utility model one kind is based on spring discharging carrier bar upside-down mounting composite die front view, and Fig. 2 is top view.
1. knockout rod in Fig. 1,2. die shanks, 3. stop pins, 4. straight pins, 5. upper bolsters, 6. upper die plates, 7. punch-pin are fixed Plate, 8. pushing block fixed plates, 9. cavity plates, 10. strippers, 11. springs, 12. punch-die fixed plates, 13. lower mold backing plates, 14. times moulds Seat, 15. unloading bolts, 16. punch-dies, 17. screws, 18. alignment pins, 19. screws, 20. guide pillars, 21. alignment pins, 22. guide pin bushings, 23. pushing block, 24. screws, 25. alignment pins, 26. punch-pin.
Embodiment
As shown in figure 1, it is described be based on spring discharging carrier bar upside-down mounting composite die, including knockout rod 1, die shank 2, stop pin 3, Straight pin 4, upper bolster 5, upper die plate 6, punch retainer 7, pushing block fixed plate 8, cavity plate 9, stripper 10, spring 11, convex-concave Mould fixed plate 12, lower mold backing plate 13, die shoe 14, unloading bolt 15, punch-die 16, screw 17, alignment pin 18, guide pillar 20, lead Set 22, pushing block 23, punch-pin 26, die shank 2 is interference fitted in upper bolster 5, and knockout rod 1 is through punch retainer 7, upper die plate 6th, die shank 2, straight pin 4 is through upper bolster 5, upper die plate 6, punch retainer 7, pushing block fixed plate 8 and cavity plate 9, alignment pin 25 fix through upper bolster 5, upper die plate 6, punch retainer 7, upper bolster 5, upper die plate 6, punch retainer 7, pushing block Plate 8 is connected with cavity plate 9 with screw 24, and punch-pin 26 is placed between upper die plate 6 and punch retainer 7, guide pin bushing 22 and the mistake of upper bolster 5 It is full of cooperation, pushing block 23 is placed between punch retainer 7 and pushing block fixed plate 8;Stripper 10, spring 11, punch-die fixed plate 12 It is connected with lower mold backing plate 13 with unloading bolt 15, punch-die fixed plate 12, lower mold backing plate 13 are connected with lower seat mould 14 with screw 19 Fixed, punch-die 16 is fastened on lower mold backing plate 13 with screw 17, and guide pillar 20 is in interference fit with die shoe 14.
The stripper 10, punch-die fixed plate 12 are machined with 4 circular grooves, are positioned for spring 11.
The carrier bar upside-down mounting composite die, die shank 2 is fixed on the upper table of punch press, and die shoe 14 is fixed under punch press Workbench.During mold work, first punching press steel disc is placed on stripper 10, punch press upper table is moved downward, punch-die 16 is first Completion puncture motion is contacted with punch-pin 26, waste material drops from lower nib, instantaneous punch-die 16 completes blanking action with cavity plate 9;On Workbench backhaul, knockout rod 1 encounters the crossbeam of punch press, and knockout rod 1 moves downward promotion pushing block 23 and pushes away the workpiece in cavity plate 9 Go out.
