The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of housing extruding compound trimming die that stretches, and structure as shown in Figure 1, this mould is comprised of upper module mechanism, elastic blank holding mechanism and lower module mechanism.Wherein, upper module mechanism comprises die shank 2, upper bolster 3, the unloading block 5 that sets gradually from top to bottom and stretches to squeeze cuts die 4, dozen rod 1 is run through at die shank 2, upper bolster 3 and unloading block 5 middle parts, and unloading block 5 is arranged on to stretch to squeeze cuts crowded the cutting in the through hole that die 4 middle parts are offered.Elastic blank holding mechanism comprises blank holder 9, push rod 10, spring top board 13, spring 14 and adjusts plate 15, blank holder 9 supports and being located at the crowded below of cutting die 4 that stretches, blank holder 9 is connected with the spring top board 13 of below through push rod 10, spring 14 is folded in spring top board 13 and adjusts between the plate 15, and spring 14 passes to blank holder 9 by spring top board 13 and push rod 10 with elastic force.Lower module mechanism is the character“door” form structure that die shoe 11 and bottom seat pad 12 form.
Cut that being provided with in the through hole stretches and squeeze and cut punch 6 stretch squeezing cut that die 4 middle parts offer crowded, this stretchings is squeezed to cut and is offered crowded cutting blade mouth on the punch 6.Stretch to squeeze to cut punch 6 and stretch to squeeze and cut the gap that is provided with 0.05-0.07mm between the die 4.Stretch to squeeze cut die 4 places partial enlarged drawing as shown in Figure 2, be improved to 50 ° about general 24 ° of adopting in the chamfering of the periphery setting of squeezing the downside cut through hole and blank holder 9 butts in by prior art, the adjustment of adopting with the utility model like this spring of pressure-pad-force be used, the problem of the structure of sharp-pointed cutting edge shape finished side cut operation deutostoma section and is being by part that can the existing processing of fine solution.The blank holder 9 that uses is the tubular blank holder, can play simultaneously flanging and positioning action.This blank holder 9 is flexibly connected with the crowded die 4 of cutting of the stretching on top through adjusting nut 7 and limited post 8, and the large I of pressure-pad-force is regulated by control limited post 8 and the distance of blank holder 9, pressure-pad-force is kept in balance can prevent from again blank is pressed to get tension simultaneously.
Spring top board 13, spring 14 and adjust plate 15 and be connected with lower module mechanism through double threaded screw 16, double threaded screw 16 runs through spring top board 13 and adjusts plate 15, spring 14 is set in the outside of double threaded screw 16, the top of double threaded screw 16 is connected with die shoe 11, and the bottom is fixed on through adjusting nut 14 and adjusts on the plate 15.
The utility model is made in for the second time stretching of operation 2 and operation 3 side cuts on the one secondary compound stretching squeezing trimming die tool by the structure innovation for existing side cut problem, and mould at first stretches to move and pushes the action of cutting edge again; This mold work process is: when the mold open state, the elastic force of spring 14 will transmit and jack-up blank holder 9 by spring top board 13 and push rod 10, at this moment, the semi-finished product that stretch first are placed on the blank holder 9, when slider of punch descending, the crowded die 4 of cutting that stretches carries out the product flanging with blank holder 9 actings in conjunction, and the concrete large I of pressure-pad-force is regulated by control limited post 8 and the distance of blank holder 9.Along with moving down gradually of slider of punch, stretch to squeeze and to cut die 4 and cut punch 6 actings in conjunction the stretching semi-finished product are carried out stretching second time with stretching to squeeze, when stretching is finished, stretch and squeeze the crowded cutting blade mouth of cutting on the punch 6 and begin to cut die 4 and the product oral area is squeezed cut out with stretching to squeeze, finish deburring.Part and waste material are squeezed from stretching by unloading block 5 and cut die 4 interior releases, and workpiece separates with the material of cutting edge thereupon.
Finish in stretching and to be about to push when cutting edge, because blank holder 9 and the crowded acting in conjunction of cutting die 4 that stretches, Tensile squeezes the impact of cutting die 4 structures, trimming allowance material after stretching for the first time just is drawn into and the crowded consistent form of mould die orifice shape of cutting that stretches, cut die 4 and move down when contacting with the blank oral area in advance when stretch squeezing, because itself gap is less, therefore, stretch to squeeze and to cut die 4 and cut punch 6 and occur to squeeze when cutting with stretching to squeeze, its squeeze cut true initial point be stretch squeeze cut punch 6 with stretch squeeze die 4 design initial points slightly below (namely by the crowded die mouth direction of cutting that stretches), in other words, namely begin along 50 ° of inclined-planes of blank to occur to squeeze to cut, the problem of the structure of sharp-pointed cutting edge shape finished side cut operation deutostoma section and is being by part that can the existing processing of fine solution.
