The specific embodiment
Embodiment of the present utility model: as depicted in figs. 1 and 2, device of the present utility model comprises cope match-plate pattern 1 and lower bolster 2; Be provided with guide pin bushing 3 on the both sides of cope match-plate pattern 1, top, the middle part of cope match-plate pattern 1 is provided with pressure head 4, and the below at cope match-plate pattern 1 middle part is connected with drift 6 through location-plate 5; Be provided with guide pillar 7 on the both sides of lower bolster 2, the concentric position of lower bolster 2 middle parts and drift 6 is provided with spring center 8, one side of spring center 8 is provided with crank throw groove 9, one side of crank throw groove 9 is provided with chute 10, be provided with V-type jacking block 11 in the chute 10, the top at lower bolster 2 middle parts is connected with holder 12, and holder 12 is provided with positioning sleeve 13.
Above-mentioned drift 6 is as Fig. 3, Fig. 4 and shown in Figure 5, and drift 6 has two, and one is thick drift, and another part is smart drift, changes and uses, and is provided with die-cut tooth 14 in the centre bore of drift 6.Drift 6 is provided with locating slot 19, and location-plate 5 is provided with alignment pin 20.
Aforesaid spring center 8 as shown in Figure 6, it is made of top 15, spring 16 and plug wire 17, top 15, spring 16 and plug wire 17 are installed in the mesopore 18 of lower bolster 2 successively.
Implementing method of the present utility model is that a cover isolated plant is installed on the forcing press, this isolated plant comprises cope match-plate pattern 1 and lower bolster 2, lower bolster 1 is fixed on the workbench of forcing press, lower bolster 1 is provided with the location and the fixture of bent axle, and the bent axle 26 that needs punching press is fixed on the lower bolster 2; Cope match-plate pattern 1 is fixed on the ram of forcing press, and drift 6 is installed on the cope match-plate pattern 1; After exerting pressure on the ram of forcing press, cope match-plate pattern 1 glides, and the drift 6 on the cope match-plate pattern 1 is gone out spline tooth on bent axle 26.Drift 6 is provided with the die-cut tooth 14 with spline parameter correspondence, for precision and the quality that guarantees punching press, drift 6 is divided into thick drift and smart drift, with thick drift the spline on the bent axle is carried out the punching press first time earlier, in order to raise the efficiency, avoid frequent replacing drift 6, part batching processing after a collection of part processing finishes, is changed smart drift again, part to process punching press for the first time carries out the punching press second time, and the product that punching press is for the second time come out promptly is qualified product; This method also can be finished the spline punching press of different parameters by changing different drift 6.Drift 6 is fixed on the cope match-plate pattern 1 through location-plate 5, and being connected of location-plate 5 and cope match-plate pattern 1 can use screw or bolt to connect.Because the spline on some bent axle is the requirement in order to locate sometimes, the crank throw 27 that is provided with a hypodontia 25 and bent axle on spline tooth has an angle requirement, in order to guarantee this angle requirement, drift 6 also must keep an identical angle with the crank throw 27 of bent axle when mounted.Therefore be provided with alignment pin 20 on the location-plate 5 of bent axle, drift 6 is provided with locating slot 19, when drift 6 is installed, the locating slot on the drift 6 19 is stuck on the alignment pin 20 of location-plate 5, to guarantee the setting angle of drift 6.
The positioner of aforesaid bent axle comprises spring center 8 and the holder 12 that is located on the lower bolster 2, and the positioning sleeve 13 that cooperates with holder 12, and holder 12 is provided with feed well 22; By the feed well on the holder 12 22 the central aperture spring center 8 on the bent axle 26 is put into holder 12, again positioning sleeve 13 is enclosed within on the bent axle 26, and positioning sleeve 13 is cooperated with holder 12, make bent axle 26 centralized positionings; Be provided with crank throw groove 9 on lower bolster 2, the crank throw 27 of bent axle is placed in the crank throw groove 9, and crank throw groove 9 limits the angle of bent axle 26; The fixture of bent axle 26 comprises the chute 10 that is located on the lower bolster 2 and the V-type jacking block 11 in the chute, after bent axle 26 is had good positioning, V-type jacking block 11 is pushed to the crank throw 27 of bent axle along chute 10.Below holder 12, also be provided with blanking groove 23, card has blanking plate 24 on the bent axle 26 in the blanking groove 23, when moving on the ram of stamping machine, blanking plate 24 restriction bent axles 26 are with moving on the ram, and the bent axle 26 of completion of processing is also released by the blanking groove 23 of holder 12 belows by blanking plate 24.
Of the present utility modelly specifically towards the tooth process be: in first being processed, the ram of forcing press is in a high position, and therefore the cope match-plate pattern of installing on the forcing press ram 1 also is in a high position, the location of at this moment more convenient bent axle 26 and fixing.Centre bore on the crank spindle is aimed at spring center 8 on the lower bolster 2 sideling, and in the crank throw groove 9 with the 26 insertion lower bolsters 2 of the crank throw on the bent axle, by the feed well 22 on the holder 12 bent axle 26 is vertically placed then, at this moment positioning sleeve 13 is enclosed within on the main shaft of bent axle, and positioning sleeve 13 is pressed into locating hole 21 on the holder 12, at this moment the centralized positioning of bent axle 26 is finished, but bent axle 26 can also have the rotation of trace.In order to prevent that in the tooth process rotation of bent axle 26 causes the angular error between spline hypodontia 25 and the crank throw 27, push the V-type jacking block 11 in lower bolster 2 upper hopper chutes 10 to crank throw 27 again, make the V-type groove on the V top type piece 11 hold out against crank throw 27, at this moment, bent axle 26 can not rotate, and fixedly operation is also finished.Blanking plate 24 is inserted from the blanking groove 23 of holder 12 belows at last again, be stuck on the bent axle 26, blanking plate 24 has two effects, the one, prevent that punching press from finishing after, move on the drift 6, because the effect of friction, bent axle 26 is being with by drift 6 and is being moved, and bent axle 26 pulls out to come out.Another effect is convenient with bent axle 26 releases that process.
Next step can install drift 6 as required on cope match-plate pattern 1, if slightly dash, use thick drift, if essence is dashed, then uses smart drift.At last just can start forcing press, carry out towards tooth.After tooth was finished, cope match-plate pattern 1 returned a high position, and positioning sleeve 13 is taken off from the main shaft of bent axle, with blanking plate 24 bent axle 26 that processes was released.Reprocess next part then by that analogy.
