Concrete, described back-up block lower limb is set to rounding.
Concrete, described spring is nitrogen spring.
Concrete, described extension section comprises some draw punchs increased successively.
Concrete, rear, described die-cut portion is also provided with portion of clapping, described portion of clapping comprises the cope match-plate pattern and to clap lower bolster of clapping, described in clap on lower bolster and be fixed with the second profiling binder block, described second profiling binder block is ringwise and be equipped with the drift of clapping that has face of clapping in the middle of it.
Further, described in clap face for annular, described in clap in the middle of face and extend the correcting head that a top is taper type.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: the utility model by increasing leveling portion in the progressive die, add the axle sleeve punch side area of plane, on the one hand complete flat first one-step forming, when making the more convenient punching of punch side structure on the other hand, material thrusts and avoids occurring wedge angle even burr.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 3, Figure 4, the shaping progressive die of the flat axle sleeve of one of the present utility model, comprise set gradually extension section 1, leveling portion 3 and die-cut portion 2, leveling portion 3 comprises leveling cope match-plate pattern 311 and leveling lower bolster 321, leveling lower bolster 321 is dragged by some nitrogen springs 324 and carries one first profiling binder block 322, ringwise and be equipped with a leveling drift 323 in the middle of it, leveling cope match-plate pattern 311 is relatively provided with a pillar support block 312 in leveling drift 323 position to first profiling binder block 322.Axle sleeve 5 axle journal 51 being connected with closed punch side 52 is formed behind the stretched portion of material strip 1, stretching distance slightly can be longer than axle journal 51 length of requirement, and be now limited to drawing process requirement, punch side 52 area of plane is little, punch side 52 and axle journal 51 transition portion have larger radian, are unfavorable for punching.The axle sleeve 5 of first one-step forming enters leveling portion 3, its stretching ledge is limited in stamping position by the first profiling binder block 322 of annular, in leveling portion 3 matched moulds process, back-up block 312 penetrates inside axle journal 51, the support to axle journal 51 horizontal direction has been coordinated with the first profiling binder block 322, in order to avoid axle journal 51 major part is out of shape from leveling drift 323 pressure at right angle, then flattening drift 323 impacts outside closed punch side 52, diminish with axle journal 51 transition portion through this punch side 52, punch side 52 area of plane increases, complete the first one-step forming of flat 511 on the one hand, when making on the other hand the more convenient punching of punch side 52 structure, material thrusts and avoids occurring wedge angle even burr.Last die-cut portion 2 cuts punch side 52, forms axle sleeve 5 structure.
As shown in Figure 4, back-up block 312 lower limb is set to rounding 3121.Back-up block 312 is when touching axle sleeve 5, and the rounding 3121 on it can play correcting effect, prevents back-up block 312 corner from thrusting axle journal 51 or hitting mould danger.
As shown in Figure 3, extension section 1 comprises the first draw punch 11, second draw punch 12 and the 3rd draw punch 13 that increase successively.Shaping like this axle journal 51 is completed by three stretcher strain, and each distortion can releasable material stress, a deformable material flowing can be avoided too large and the danger that thrusts.
As shown in Fig. 3, Fig. 6, rear, die-cut portion 2 is also provided with portion 4 of clapping, portion 4 of clapping comprises clap cope match-plate pattern 411 and lower bolster 412 of clapping, clap and lower bolster 412 is fixed with the second profiling binder block 422, second profiling binder block 422 ringwise and be equipped with the drift 423 of clapping that has face 4231 of clapping in the middle of it.After punching, the thrusting edge configuration and generally can there is error of axle sleeve 5, by clapping, portion 4 can revise again to it, its principle is: the axle sleeve 5 after punching is contained in the second profiling binder block 422 inner position, axle sleeve 5 compresses by cope match-plate pattern 411 of clapping after matched moulds, drift 423 of clapping stretches out, and impacts the lower limb of axle journal 51 with face 4231 of clapping, and makes it form at the bottom of annular flat 511.
As shown in Figure 6, Figure 7, the correcting 4232 that a top is taper type, for annular, is extended in the face 4231 of clapping in the middle of face 4231 of clapping.In order in the step that prevents from clapping, axle journal 51 inwardly subsides, a correcting of drift 423 front end of clapping 4232 can penetrate axle journal 51 inside and provide support, and face 4231 structure of clapping of annular not affect at the bottom of annular flat 511 normally shaping.
Utilize the axle sleeve 5 that the above progressive die is processed, its ring width of flat 511 can reach more than 1.0mm, meets customer demand completely, simultaneously the smooth impulse-free robustness of plane of thrust.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
