Description
Technical field
The utility model relates to cupping tool technical field, particularly a kind of secondary deep-drawing mould.
Background technology
Drawing is to utilize cupping tool the good plate blank of stamping-out to be pressed into the hollow object of various openings, or Manufactured open hollow part is processed into a kind of processing method for stamping of other shape hollow object.The feature of cupping tool is that structure is relatively simple, and with blanking die comparison, working portion has larger fillet, and surface quality requires high, and punch and matrix gap is slightly larger than sheet thickness.
In drawing process, blank is subject to the effect of punch drawing pressure, in the radially generation tensile stress of flange blank, tangentially produces compression stress.Under their acting in conjunction, flange deformation region material generation plastic deformation, and be constantly drawn into formation tube drawing in die.
Under normal circumstances, only need to be just plastic by once drawing for the product that drawing depth is less, while using existing Drawing Die to carry out drawing and forming, mould is less to the pressure-plate-force of workpiece, cause surface of the work to crease easily, workpiece surface quality is poor, and waster rate is high.Along with drawing depth increases, the plastic deformation quantitative change that flange deformation region occurs is large, the easy drawing crack in its flange deformation region, and also workpiece after drawing is easily stuck in drawing die, is difficult for taking out, and reduced operating efficiency, even causes that mould damages.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide that a kind of pressure-plate-force to workpiece is large, workpiece surface quality good, do not crease easily, the low and drawing of waster rate complete after the secondary deep-drawing mould that easily takes out from drawing die of workpiece.
The purpose of this utility model is achieved through the following technical solutions: a kind of secondary deep-drawing mould, it comprises die shoe, upper bolster, guide pillar, drawing die and drawing punch, many guide pillars are vertically fixed on die shoe, upper bolster and guide pillar are slidably matched, and guide pillar is vertical with the end face of upper bolster, between each described root guide pillar and upper bolster, be also provided with guide pin bushing, guide pin bushing is fixed on upper bolster, the centre position, lower surface of upper bolster is installed with drawing die, the centre position, upper surface of die shoe is also fixed with punch retainer, drawing punch is vertically fixed on punch retainer, drawing punch coordinates with drawing die, the end face center of upper bolster is connected with knock-pin by threaded engagement, and the lower end of knock-pin is provided with ejection slider, and the bottom of ejection slider and drawing die are slidably matched.
Between described drawing die and punch retainer, be also provided with blank clamping plate, blank clamping plate and drawing punch are slidably matched.
On described die shoe, be also provided with stripper bolt, stripper bolt is connected by threaded engagement with die shoe, and stripper bolt is passed punch retainer and is connected by threaded engagement with blank clamping plate.
On the end face of described drawing die, be also provided with cushion pins, the lower end of cushion pins withstands on blank clamping plate.
On described die shoe, be also provided with helium spring, helium spring passes punch retainer and withstands on blank clamping plate, and helium spring aligns with cushion pins.
The utlity model has following advantage:
1, blank clamping plate are set on drawing punch, in the time of drawing and forming, blank clamping plate provide enough pressure-plate-forces by helium spring, and workpiece drawing between blank clamping plate and drawing die is carried out smoothly.
2, drawing die coordinates with drawing punch, and applies pressure-plate-force by blank clamping plate, avoids working surface wrinkling, ensures the surface quality of workpiece.
3, on drawing die, be provided with cushion pins, after drawing puts in place, cushion pins withstands blank clamping plate, pressure-plate-force is acted on cushion pins completely, drawing punch stops moving forward, the workpiece obtaining not only has the drawing depth of degree of precision, and is not prone to drawing crack phenomenon, and waster rate significantly reduces.
4, at upper bolster middle part, knock-pin is set, and coordinates with ejection slider, after drawing completes, knock-pin moves downward, and drives ejection slider, and ejection slider ejects workpiece, and workpiece easily takes out from drawing die.
