Detailed description of the invention
As Fig. 2, a kind of deep drawn axle sleeve moulding process, step comprises:
(1) stretching step: be the cylindricality neck that one end is connected with stretching bottom surface by the material multistage stretching of plane;
(2) punch out step: punch out inside and outside through through hole in stretching bottom center;
(3) straight flange step: the sealing surface material outside through hole is expanded for the extended surface concordant with cylinder;
(4) flanging step: the outer rim of extended surface is turned down as flanging.
Below in conjunction with specific embodiment, the present invention is described in further detail.
As shown in Figure 3, the shaping progressive die of a kind of deep drawn axle sleeve of the present invention, comprises extension section 1, punching portion 2 successively, directly turns over portion 3 and valgus 4.Extension section 1 comprises stretching patrix 11, and stretching patrix 11 is provided with three draw punchs increased successively (the first draw punch 111, second draw punch 112, the 3rd draw punch 113).Metal material belt through out-of-date, first stretches in this progressive die in extension section 1, and after three times stretch, namely material forms neck 52 preliminary structure of cylindricality, and the opposite side of neck 52 is connected with stretching bottom surface (mark) and does not thrust.
As shown in Figure 4, punching portion 2 comprises punch upper die 21 and punching counterdie 22, and punch upper die 21 is provided with pierce punch 211, and punching counterdie 22 is provided with the first profiling tray 221, first profiling tray 221 and is provided with the material-dropping hole 2211 of dodging pierce punch 211.During punching, shaft sleeve workpiece 5 after stretching is spacing by the first profiling tray 221, along with the 2-in-1 mould in punching portion, pierce punch 211 is by the stretching bottom center place's perforate at shaft sleeve workpiece 5, expand from tapping at next step in order to stretching bottom surface, can be discharged from material-dropping hole 2211 by the waste material sweeping away one piece of suitable size.
As shown in Figure 5, directly turn over portion 3 to comprise and directly roll up mould 31 and directly turn down mould 32, directly roll up mould 31 be provided with external diameter the same with the 3rd draw punch 113 external diameter directly turn over drift 311, directly turn down mould 32 be provided with the second profiling tray 321, second profiling tray 321 be provided with dodge directly turn over drift 311 dodge hole 3211.When directly turning over, the shaft sleeve workpiece 5 after punching is spacing by the second profiling tray 321, and along with directly turning over portion 3 matched moulds, directly turning over drift 311 will pass from shaft sleeve workpiece 5 inside, and the stretching bottom surface after punching is expanded into cylindricality facade, add the distance at cylindricality position.
As shown in Figure 6 to 8, valgus 4 comprises turn up patrix 41 and the counterdie 42 that turns up; The counterdie 42 that turns up is provided with the drift 422 and from the drift 423 that turns up passed in the middle of drift 422 of clapping of clapping of the profiling lateral pressing block 421 of a pair activity, annular, clap drift 422 between a pair profiling lateral pressing block 421, the cross section that is provided with of a pair profiling lateral pressing block 421 top symmetry is semicircular binder groove 4211, profiling binder block 421 is provided with the heavy face 4212 that is positioned at binder groove 4211 bottom, profiling lateral pressing block 421 bottom is provided with oblique pin 4213, and the counterdie 42 that turns up is provided with the oblique guiding groove 42a for guiding oblique pin 4213; The patrix 41 that turns up is provided with locating core 411, and locating core 411 is relative with the drift about 423 that turns up.When turning up, shaft sleeve workpiece 5 is held in the palm the top be loaded between two profiling lateral pressing blocks 421, during matched moulds, it is inner that the locating core 411 of patrix 41 of turning up penetrates into shaft sleeve workpiece 5, complete axis Primary Location, it is descending together with two profiling lateral pressing blocks 421 that the descending patrix 41 that turns up press against shaft sleeve workpiece 5, due to the interaction of turn up counterdie 42 tiltedly guiding groove 42a and profiling binder block 421 and oblique pin 4213, two descending profiling lateral pressing blocks 421 occur close to motion simultaneously, two cross section is that semicircular binder groove 4211 will be combined into one by the cylindrical cavity of shaft sleeve workpiece 5 neck 52 periphery clamping, complete the axis location of shaft sleeve workpiece 5, when the patrix 41 that turns up continues descending, turned over straight neck 52 lower limb touch turn up drift 423 and occur tentatively extend out, time descending again, the lower limb extended out touches drift 422 of clapping and is namely formed as flanging 53, heavy face 4212 below binder groove 4211 provides the receiving space of flanging 53, makes flanging 53 better with the depth of parallelism of bottom 51.
Binder groove 4211 length is greater than the length of the 3rd draw punch 113, the final stretching distance therefore in stretching step be less than shaft sleeve workpiece 5 rely on binder groove 4211 to turn up after the length of neck 52.In practical application, the length required when neck 52 is 14.5mm, then the length of binder groove 4211 is 14.5mm, and the length of the 3rd draw punch 113 only needs 12-13mm, is less than the draw punch length requirement of more than 16mm in prior art.These main points importance is in process: under identical neck 52 length and flanging 53 ring width require prerequisite, shorten deep drawn distance, in such deep drawn, the deflection of material reduces, material thickness has had better guarantee, therefore manufacturing scrap rate obviously reduces, the overall length that stretches is less than neck 52 and requires the problem of length then by the stretching bottom surface of opening is turned over straight length to supply, and therefore the specification of final shaft sleeve workpiece 5 also can reach standard-required.
Stretching step restrained stretching R angular radius 5-8mm.Because stretching after-drawing bottom surface also will be carried out turning over straight, if the R angular radius in stretching step is too little, material can be weaker in turnover region, repeat stressed in also easily there is risk of breakage.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
