In figure, 1. cope match-plate pattern 2. lower bolster 3. guide pin bushing 4. guide rod 5. drive rod 6. spring I 7. corrects drift 8. pilot sleeve 9. guide groove plate 10. gusset 11. skewback 12. spring II 13. axle bed 14. ejector beam 15. stripper 16. and locates counterdie 17. pointed tooth 18. pierce punch.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing 1 pair of the utility model.
This excavator forging pointed tooth installing hole die cutting die, comprise lower bolster 2 and cope match-plate pattern 1, described lower bolster 2 is vertically provided with some guide rods 4, cope match-plate pattern 1 is provided with some guide pin bushings 3, each guide rod 4 slides and is plugged in corresponding guide pin bushing 3, also comprise the location counterdie 16 be vertically installed on lower bolster 2, be installed on the pilot sleeve 8 on cope match-plate pattern 1, slide and be plugged in sleeve 8 and the correction drift 7 be positioned at directly over the counterdie 16 of location, be arranged at location two axle beds 13 at counterdie about 16 two ends and horizontal slip and be plugged in pierce punch 18 in axle bed 13, correct between drift 7 and cope match-plate pattern 1 and be provided with spring I 6, correct drift 7 lower end and be provided with the shrinkage pool matched with pointed tooth 17 head end size, location counterdie 16 matches with the hole size of pointed tooth 17 lower end, when forcing press drives cope match-plate pattern 1 to move down, pointed tooth 17 is vertically fixedly clamped by correcting drift 7 and locating counterdie 16, two pierce punches drive its transverse shifting to complete punching by drive unit.To treat that the pointed tooth 17 of punching is sleeved on the counterdie 16 of location, forcing press drives cope match-plate pattern 1 descending, and pointed tooth 17 upper end is pushed down by correction drift 7, realizes the fixing of pointed tooth 17.Cope match-plate pattern 1 continues descending, now corrects drift 7 Compress Spring I 6, and drive unit promotes pierce punch 18 horizontal movement thus realizes pointed tooth 17 punching to form installing hole.Therefore improve production efficiency.
Drive unit can be following structure, it comprises the guide groove plate 9 be arranged on lower bolster 2, to be vertically fixed on cope match-plate pattern 1 and two drive rods 5 being slidably matched of outboard end and guide groove plate 9 and the skewback 11 that is arranged at pierce punch 18 outboard end, spring II 12 is set on pierce punch 18, and its two ends contact with skewback 11 and axle bed 13 respectively, skewback 11 outer face is the inclined-plane of 45 °, drive rod 5 lower surface is the inclined-plane of 45 °, and drive rod 5 lower surface parallels with skewback 11 outer face.When lower bolster 2 moves down, it drives drive rod 5 to move straight down along guide groove plate 9, and drive rod 5 makes skewback 11 drive pierce punch 18 transverse shifting finally to realize pointed tooth 17 punching installing hole by the inclined-plane of lower end and the inclined-plane sliding friction of skewback 11.When cope match-plate pattern 1 upwards backhaul time, under the elastic force of spring II 12, its drive pierce punch 18 move laterally, realize exiting from the hole of punching, now can conveniently by the pointed tooth 17 after punching from location counterdie 16 take out.
Can also comprise slip cap and be loaded on the stripper 15 of locating on counterdie 16, stripper 15 lower end is connected with forcing press ejector beam 14.When press ram return, forcing press ejector beam 14 promotes stripper 15 and moves up, and is released by pointed tooth 17, achieve the function of automatic material returning, further increase production efficiency from location counterdie 16.
The some gussets 10 be connected between guide groove plate 9 and lower bolster 2 can also be comprised.Gusset 10 can improve the fix tightly soundness of guide groove plate 9, prevents its stress deformation from damaging, improves the reliability of use.
