Description
Technical field
The utility model relates to a kind of mould structure, particularly relates to a kind of high accuracy punch die structure for plank punching.
Background technology
Making plank that back support or seat support due to threading or fixed demand often needs to stamp some through holes, at present, punching is general adopts artificial boring or punch press punching, and artificial driller not only labor strength is large, drilling efficiency is low, and hole position error is larger; Punch press punching needs punching die to coordinate, and the common punching die often fixing rear adjusting position that is difficult to, and mould steadiness is poor, also may increase hole position error, therefore needs to design special punching die structure.
Utility model content
The utility model is in order to solve the defect and deficiency that exist in above-mentioned prior art, provide one and can not only reduce labor strength, improve drilling efficiency, and punching die position is adjustable, steadiness is good, can improve the high accuracy punch die structure for plank punching of position, hole accuracy.
The technical solution of the utility model: a kind of high accuracy punch die structure for plank punching, comprise mould table, be fixed on the upper bolster in mould table, die shoe, be arranged on the thimble between upper bolster and die shoe and be arranged on the some red needles bottom upper bolster, described mould table is provided with the compact heap that four are pushed down die shoe four angles, a screw rod is provided with in the middle part of described compact heap, be fixed on bottom described screw rod in mould table, be pressed on screw rod by a clamp nut in the middle part of described compact heap, compact heap one end compresses die shoe, the compact heap other end is supported by a back-up block, the height of described back-up block and the height of die shoe match, the height of described back-up block and the height of die shoe match, described die shoe is provided with some round boss, the position of described round boss is corresponding with the position of red needle, the middle part of described round boss is provided with red needle accommodation hole.
The utility model adopts compact heap to compress die shoe, adopt screw rod and clamp nut to regulate compact heap simultaneously, it is made to reduce labor strength, improve drilling efficiency, and punching die position is adjustable, steadiness is good, position, hole accuracy can be improved, round boss the height that suitably can improve plank is set, shorten the distance between red needle and plank, thus the accuracy of red needle punching can be improved, the distance can guaranteeing red needle undershoot is set can not shortens of red needle accommodation hole, guarantee that its lower punch power can not diminish, and well protection red needle is not damaged.
Preferably, be provided with upper padding plate on the downside of described upper bolster, described red needle is fixed on upper padding plate, is provided with lower bolster on the upside of described die shoe, and the height of described back-up block and the height of lower bolster match, and described round boss is arranged on lower bolster.
This kind of structure makes mould structure more stable, and the compression of compact heap to die shoe is more effective.
Preferably, be arranged with rubber protective ring outside described red needle, described thimble quantity is two, and two thimbles are that diagonal angle is arranged.
This kind of structure makes red needle well be protected.
Preferably, be provided with strip through hole in the middle part of described compact heap, the width of described strip through hole is greater than the diameter of screw rod, is provided with pad between described clamp nut and strip through hole.
This kind of structure makes the position of compact heap to regulate, thus the convenient position adjustments to mould.
Preferably, the height of described screw rod is higher than the height of back-up block, and the width of described back-up block is greater than the width of compact heap.
This kind of structure makes the compression of compact heap to die shoe more solid and reliable.
The utility model adopts compact heap to compress die shoe, and adopt screw rod and clamp nut to regulate compact heap, make it to reduce labor strength, improve drilling efficiency, and punching die position is adjustable, steadiness is good, can improve position, hole accuracy simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1. mould table, 2. upper bolster, 3. upper padding plate, 4. die shoe, 5. lower bolster, 6. compact heap in figure; 7. screw rod, 8. back-up block, 9. thimble, 10. red needle, 11. rubber protective rings; 12. round boss, 13. red needle accommodation holes, 14. strip through holes, 15. clamp nuts, 16. pads.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, a kind of high accuracy punch die structure for plank punching, comprise mould table 1, be fixed on the upper bolster 2 in mould table 1, die shoe 4, the some red needles 10 being arranged on the thimble 9 between upper bolster 2 and die shoe 4 and being arranged on bottom upper bolster 2, mould table 1 is provided with the compact heap 6 that four are pushed down die shoe 4 four angles, a screw rod 7 is provided with in the middle part of compact heap 6, be fixed in mould table 1 bottom screw rod 7, be pressed on screw rod 7 by a clamp nut 13 in the middle part of compact heap 6, compact heap 6 one end compresses die shoe 4, compact heap 6 other end is supported by a back-up block 8, the height of back-up block 8 and the height of die shoe 4 match, die shoe 4 is provided with some round boss 12, the position of round boss 12 is corresponding with the position of red needle 10, the middle part of round boss 12 is provided with red needle accommodation hole 13.Be provided with upper padding plate 3 on the downside of upper bolster 2, red needle 10 is fixed on upper padding plate 3, is provided with lower bolster 5 on the upside of die shoe 4, and the height of back-up block 8 and the height of lower bolster 3 match, and round boss 12 is arranged on lower bolster 5.Be arranged with rubber protective ring 11 outside red needle 10, thimble 9 quantity is two, and two thimbles are that diagonal angle is arranged.Be provided with strip through hole 14 in the middle part of compact heap 6, the width of strip through hole 14 is greater than the diameter of screw rod 7, is provided with pad 16 between clamp nut 15 and strip through hole 14.The height of screw rod 7 is higher than the height of back-up block 8, and the width of back-up block 8 is greater than the width of compact heap 6.
