Abstract
A general nitrogen spring-type mold frame comprises a frame body composed of an upper mold plate and a lower mold plate, and the upper mold plate of the frame body can move vertically close to the lower mold plate downwards; a male mold and a mold cavity are arranged on the corresponding positions of the upper and lower mold plates respectively; the male mold is fixed by a male mold fixing plate connected with the upper mold plate; a blank holder force supply device is arranged on the male mold fixing plate and is connected with a pressure plate for supplying blank holder force for the pressure plate; a guide plate is arranged on the mold cavity for positioning the plate material on the mold cavity; the blank holder force supply device is a nitrogen spring, and the blank holder force and force point of the nitrogen spring are controllable and adjustable. The general nitrogen spring-type mold frame can adjust the capacity of the blank holder force and the force point position at any time, maintains the blank holder force constant during drawing process, effectively prevents the defects of corrugation and crack during molding, is applicable to common pressure machines, and has good generality.
Description
Technical field
The utility model relates to a kind of pull and stretch mould bases, is specifically related to the general pull and stretch mould bases of a kind of nitrogen spring formula.
Background technology
The essence of drawing distortion is exactly the transfer of " unnecessary triangle ", and this part metal shifts from the flange position to the barrel height in shearing stress with radially under the effect of tension, if it is too big to shift resistance, material will be by drawing crack, if circumferential compressive force is excessive, ledge zone will be wrinkling.Therefore wrinkling in flow process in order to prevent metal, except correctly carrying out the tension and compression technology Calculation, adopting flange fixing installation is the most effective at present wrinkle resistant measure, and the size of pressure-pad-force directly has influence on presses the quality of drawing part, also is that one of main technologic parameters that can metal flow is drawn in control.In the cupping tool design, conventional flexible member is spring, rubber, air cushion etc., and these flexible members all have its pluses and minuses, and the common problem that exists can not provide elastic force pressure accurately exactly, influence the pull and stretch effect, in the Drawing Die forming process, be prone to break, problem such as wrinkling.In present punching press books, again not accurately the pressure-pad-force computing formula can look into, so aborning, pressure-pad-force selected and adjusting generally all is to carry out according to designer or the experience of adjusting the workman.So just have influence on the steady quality that draws product, the height of percent defective extends the cycle of debugging and correction mould.
Summary of the invention
The utility model provides a kind of nitrogen spring formula pull and stretch universal die set, by changing the structure of traditional cupping tool, solves breaking of being prone in traditional Drawing Die forming process, problem such as wrinkling, no servicing unit, and applicability is wide, formation of parts precision height.
Technical solution of the present utility model is:
A kind of nitrogen spring formula pull and stretch universal die set comprises a support body that is made of cope match-plate pattern and lower bolster, and the cope match-plate pattern on the described support body can be drawn close motion to lower bolster vertically downward; Described cope match-plate pattern and lower bolster are respectively arranged with the punch and the die of position correspondence; Described punch is fixed by punch retainer, and described punch retainer is connected with cope match-plate pattern; Described punch retainer is provided with the pressure-pad-force feedway, and described pressure-pad-force feedway is connected with holding pad, and provides pressure-pad-force to holding pad; Also be provided with stock guide on the described die, this stock guide is realized the location to the plate on the die; Its special character is: described pressure-pad-force feedway is a nitrogen spring, and the pressure-pad-force and the stress point of this nitrogen spring are controlled, adjustable.
Above-mentioned support body is the support body that cope match-plate pattern and lower bolster connect and compose by the guide pillar guide pin bushing.
Above-mentioned punch retainer is connected with cope match-plate pattern with screw by pin.
Advantage of the present utility model is: not only can regulate the size of pressure-pad-force and the position of stress point at any time, can also on ordinary press, realize drawing and forming technology, can also effectively solve breaking in traditional forming process, defective such as wrinkling, applicability is wide, cost is low, formation of parts quality height; The utility model adopts nitrogen spring that pressure-pad-force is provided, and nitrogen spring pressure-pad-force in the drawing and forming process keeps constant, can effectively prevent the wrinkling and defective of breaking in the forming process, and can improve the drawing part quality.

Fig. 1 is a structural representation of the present utility model.
Drawing reference numeral explanation: 1-lower bolster, 2-pin, 3-guide pillar guide pin bushing, 4-die, 5-stock guide, 6-punch, 7-holding pad, 8-nitrogen spring, 9-punch retainer, 10-cope match-plate pattern, 11-screw.
The specific embodiment
Referring to Fig. 1, a kind of nitrogen spring formula pull and stretch universal die set comprises a support body that is made of cope match-plate pattern 10 and lower bolster 1, and the cope match-plate pattern 10 on the support body can be drawn close motion to lower bolster 1 vertically downward; Cope match-plate pattern 10 and lower bolster 1 are respectively arranged with the punch 6 and the die 4 of position correspondence; Punch 6 is fixing by punch retainer 9, and punch retainer 9 is connected with cope match-plate pattern 10; Punch retainer 9 is provided with the pressure-pad-force feedway, and the pressure-pad-force feedway is connected with holding pad 7, and pressure-pad-force is provided for holding pad 7; Also be provided with stock guide 5 on the die 4, the plate on 5 pairs of dies 4 of this stock guide is realized the location; The pressure-pad-force feedway is a nitrogen spring 8, and the pressure-pad-force and the stress point of this nitrogen spring 8 are controlled, adjustable; Wherein support body is the support body that cope match-plate pattern 10 and lower bolster 1 connect and compose by guide pillar guide pin bushing 3; Wherein punch retainer 9 is connected with cope match-plate pattern 10 with screw 11 by pin 2.
During work, this mould bases is installed on the ordinary press, between punch 6 and die 4, place and treat the pull and stretch plate, plate is realized the location by stock guide 5, during pull and stretch, cope match-plate pattern 10 moves downward along guide pillar guide pin bushing 3, the nitrogen spring 8 that drive is installed on the punch retainer 9 moves downward, nitrogen spring 8 applies power for holding pad 7, after treating that the pull and stretch plate is applied in constant pressure-pad-force, cope match-plate pattern 10 continues to move downward simultaneously, drives punch 6 and moves downward, plate is drawn in the die 4, realizes drawing and forming.
