Detailed description of the invention
Below according to accompanying drawing, this utility model is described further.
As shown in Figure 1, punching structure includes upper mold and lower mold, upper mold includes upper cover plate, upper bolster, fixed plate, fixed plate backing plate, stripper, stripper backing plate, stripper bolt, spring, nitrogen spring, inner guiding post, drift, the lower section of upper cover plate 14 connects upper bolster 15, the lower section of upper bolster 15 connects fixed plate backing plate 16, the lower section of fixed plate backing plate 16 connects fixed plate 17, and the lower section of fixed plate 17 is provided with stripper backing plate 18, and the lower section of stripper backing plate 18 connects stripper 19；It is provided with plug screw 10 in described upper cover plate 14, the lower end of plug screw 10 abuts one end of spring 11, the other end of spring 11 abuts one end of stripper bolt 12, the other end of stripper bolt 12 connects one end of drift 28, and the other end of described drift 28 extends through fixed plate 17, stripper 19 and stripper backing plate 18；Being positioned at the fixed plate backing plate 16 on the left of drift 28 and be provided with another stripper bolt 13, the lower end of another stripper bolt 13 extends through fixed plate backing plate 16, fixed plate 17 is connected with stripper backing plate 18；Being positioned at the fixed plate 17 on the right side of drift 28 and be provided with inner guiding post 9, the lower end of inner guiding post 9 extends through fixed plate 17, stripper backing plate 18 and stripper 19, and is positioned at the lower section of stripper 19；Being positioned at the upper cover plate 14 on the right side of inner guiding post 9 and be provided with nitrogen spring 3, the lower end of nitrogen spring 3 extends through upper bolster 15, fixed plate backing plate 16 and is positioned at fixed plate 17；Lower mold includes concave template, concave template backing plate, die shoe, lower mold foot, lower shoe, interior guide pin bushing, lower shoe 24 be connected above lower mold foot 23, lower mold foot 23 be connected above die shoe 22, die shoe 22 be connected above concave template backing plate 21, concave template backing plate 21 be connected above concave template 20；It is positioned at the concave template 20 below inner guiding post 9 and is embedded with guide pin bushing 25, and the position of interior guide pin bushing 25 is corresponding with inner guiding post 9.
Upper cover plate 14 is connected by bolt and pin with upper bolster 15.
Upper bolster 15, fixed plate backing plate 16 and fixed plate 17 are connected by bolt and pin.
Stripper 19 is connected by bolt and pin with stripper backing plate 18.
The lower end of nitrogen spring 3 connects push rod.
Concave template 20, concave template backing plate 21 and die shoe 22 are connected by bolt and pin.
Under the effect of nitrogen spring 3 power, nitrogen spring 3 push rod directly withstands on stripper backing plate 18.Owing to there being the effect of another stripper bolt 13, stripper 19 and stripper backing plate 18 the most down move.Stripper bolt 12 now hangs in fixed plate 17.Under the effect of spring 11 and plug screw 10, drift 28 will move downward until stripper bolt 12 hangs over above fixed plate backing plate 16.Punch press moves downward until stripper 19 contacts with sheet material 29, and spring 11 now starts pressurized, and when punch press continues to move downward, upper bolster 15, upper cover plate 14, fixed plate 17 move downward, and drift 28 is owing to there being the effect of spring 11, will not move downward.When fixed plate backing plate 16 contacts with drift 28, drift 28 just starts to do work downwards.Punch press continues to move downward, and drift 28, under the guide effect of stripper 19, completes stamping-out.In discharge process, punch press top shoe moves upward with upper bolster 15, fixed plate 17, because now nitrogen spring 3 is in compressive state, withstands on drift 28 spring 11 above and is also at compressive state, and this power is F1, and direction is downward.Moving upward of upper bolster 15, drift 28 is downward with the stiction of stripper 19, and this power is F2.The stripping force of drift 28 is downward, and this power is F3.Upwards, this power is F4 to the force of sliding friction of drift 28 and fixed plate 17.F1+F2+F3 is far longer than F4.When slide block moves upward, drift 28 is motionless, and fixed plate 17 is to move upward relative to drift 28.When slide block movement to fixed plate backing plate 16 contacts with the stripper bolt 12 above drift 28, now stripper bolt 12 starts to bear stripping force.Slide block continues up, and drift 25, under the induced effect of stripper bolt 12, starts to withdraw from sheet material 29, then returns to inside stripper 19.When another stripper bolt 13 contacts with fixed plate 17, punching press discharge process curves.Drift 28 does not the most leave the targeting part of stripper 19.This guarantees when again doing work, drift 28 has the guide effect of stripper 19.Slide block continues up, and stripper 19 leaves sheet material, and at this moment state returns to the die opening state of Fig. 1.
Emphasis of the present utility model is exactly that the conventional fixed deck mode of drift is become slip fixed form, and the guiding of drift is apart from elongated.Discharging stroke is big, does not increase mould template thickness.The cost of mould is substantially reduced, and improves the competitiveness of enterprise.
