The specific embodiment
Fig. 1 and Fig. 2 show a kind of clutch case jointly, this clutch case has edge part a1, side wall portion a2 and bottom a3, edge part a1 is provided with a plurality of connecting holes that supply connecting bolt to pass, side wall portion a2 is provided with three areole a4 that supply clutch lever to pass, and bottom a3 is provided with a bottom outlet that supplies line shaft to pass.B1 represents is edge part near areole a4, and b2 represents is edge part away from areole a4.
Fig. 3 shows a kind of diel, it can be with the clutch case that produces through the blank that obtains after blanking and the punching as depicted in figs. 1 and 2, after machining, the edge part of clutch case and the areole of side wall portion do not need finishing, thereby can improve the production efficiency of clutch case greatly, and effectively reduce production costs.
As shown in Figure 3, this diel comprises punch 5, die 3 and blank holder 4, and blank holder 4 is movably set in the outside of punch 5 and corresponding with die 3.In fact, for " will use the best steel to make the knife's edge ", and for easy to process and purpose that be convenient to keep in repair, punch 5, die 3 and blank holder 4 are made kit form usually, for this point, though not painstakingly expression in the accompanying drawing provided by the utility model, but, undoubtedly, utility model people is the same with those of ordinary skill in the art, and this point is known.
Die 3 is fixedlyed connected with top mold frame 1 by die block 2, and top mold frame 1 is used for transmitting the drawing pressure F1 (as shown in Figure 5) of forcing press.Punch 5 is fixed on down on the mould bases 7, and following mould bases 7 remains static all the time.Following ejecting mechanism 8 is used for transmitting the pressure-pad-force F2 (as shown in Figure 5) of forcing press.During pull and stretch, die 3 is descending, under the effect of punch 5 plate is pressed in the described die 3.
The diel that the utility model disclosed also comprises following structure, makes it unusual.
As shown in Figure 3, blank holder 4 is provided with chute, described chute be arranged on blank holder 4 with described die 3 facing surfaces on and radially extend, described chute has three, and is corresponding with an areole a4 position of clutch case respectively.Slide block 61 all is installed in each chute, one end of the close described punch 5 of described slide block 61 is provided with and the corresponding step of the thickness of described plate, end away from described punch 5 of described slide block 61 is provided with stressed inclined-plane, described step is used for leaning the edge part b1 near areole, generally, the shape of the edge part of the shape of the step surface of described slide block 61 and described clutch case is suitable.
The lower end of voussoir 62 is fixedly mounted on down on the mould bases 7, thereby it remains static all the time.The upper end of voussoir 62 is provided with and suitable application of force inclined-plane, described stressed inclined-plane, is equipped with the axial hole that is used to hold described voussoir 62 on described blank holder 4 and the described die 3.
The application of force inclined-plane of mutual voussoir 62 of fitting and the stressed inclined-plane of slide block 61, the downward movement of die 3 can be transformed into radially inside the moving of slide block 61, the speed that slide block 61 moves is decided by the size of inclination angle of inclined plane, the contraction speed of edge part a1 then depends on pull and stretch speed, i.e. the downstream rate of die 3.Because slide block 61 leans on the close edge part part b1 of areole a4, as long as the translational speed that makes slide block 61 is identical with contraction speed away from the edge part b2 of areole, just can guarantee near the plate of the edge part of areole with away from the plate of the edge part of areole synchronous always, thereby make the edge part a1 of clutch case and areole a4 can guarantee very high pull and stretch precision, after machining, edge part a1 and areole a4 do not need finishing, thereby improved greatly clutch case production efficiency, reduced production cost.Use the sheet metal deep drawing principle, by the test of calculating and limited number of time, such inclination angle of inclined plane is confirmable fully.
During die sinking, slide block 61 should be got back to initial position, so also be provided with elastic position rebounding device between slide block 61 and described blank holder 4, described elastic position rebounding device is preferably extension spring.
Also be provided with a flange die 31 in the centre of die 3, be used for the bottom outlet of bottom a3 is carried out flange.
In order to further specify the operation principle of above-mentioned drawing die, the utility model also shows the duty of drawing die when blowing, flanging and the pull and stretch respectively by Fig. 4, Fig. 5 and Fig. 6.
As shown in Figure 4, the blank that forms behind punching and the blanking is placed on the blank holder 4, the step of slide block 61 leans on the plate of the edge part b1 of close areole.
As shown in Figure 5, under the effect of tensile force F1, die 3 is descending.Under the effect of pressure-pad-force F2, blank holder 4 compresses with the edge part a1 of descending die 3 with blank.
As shown in Figure 6, under the acting in conjunction of tensile force F1 and pressure-pad-force F2, die 3 and blank holder 4 are descending together, plate is pressed in the die 3, simultaneously, slide block 61 radially moves inward, and the translational speed of described slide block is identical with the contraction speed of the plate of described edge part away from areole.When finishing pull and stretch, flange die 31 is finished the flange that bottom a3 goes up bottom outlet.
The utility model is simple in structure, can finish the pull and stretch and the flange of clutch case simultaneously, and the edge part a1 behind the pull and stretch and areole a4 do not need finishing, thus improved greatly clutch case production efficiency, reduced production cost.
The utility model is not limited to above-mentioned concrete embodiment, its essence is by a kind of confinement plate materials flow moving device or method, make near the plate of the edge part of areole with away from the plate of the edge part of areole synchronous always in drawing process, thereby guaranteed the pull and stretch precision of edge part and areole.Diel that the utility model disclosed and process for stamping are widely used in making holes at lateral wall hollow parts such as clutch case.
