Description

Manufacture the special tooling of different-diameter step spinning belt pulley

Technical field

The utility model belongs to automobile engine inner panel spinning different-diameter step belt pulley processing technique field, relates to A kind of and special tooling for manufacturing step belt pulley.

Background technology

At present, lightweight all is being pursued in automobile, motor, farm machinery, to reach more preferable energy-saving and emission-reduction purpose, made It is more and more with spinning belt pulley, but use the belt pulley of single group mostly at present, as this multistage compound belt wheel is few See, if multigroup belt wheel must be used, be mostly by screw or welding manner make multiple belt pulley sets dress up one it is whole Body.Relative to this multiple belt pulley combining structures, multi-stage stairs formula belt pulley is an entirety, is not required to connect otherwise It is connected into as an entirety, such material consumption is few, cost is low, efficiency high, performance are good.But different-diameter staircase structural model belt Wheel mutually requires spinning process higher, easily occurs up/down steps teeth groove decentraction during spinning, bounce is big, or the installation of teeth groove The defects of size is unstable.

The content of the invention

In order to overcome the above-mentioned deficiency of prior art, the utility model, which provides one kind and solves upper and lower teeth groove decentraction, asks Topic, installation dimension instability problem, the spinning work of the manufacture different-diameter step spinning belt pulley of product quality is effectively ensured The special tooling of skill.

The technical solution of the utility model is：The core fixture one of spinning first order teeth groove is installed on spinning machine, Core fixture one includes upper core one, lower core one；There is an annular groove lower end of upper core one, the physical dimension of annular groove with The first order teeth groove upper end size of shaping to be processed is adapted, and there is an inclined-plane with taper the lower upper surface of core one, on lower core one Inclined-plane of the end face with taper is adapted with the first order teeth groove lower end size of shaping to be processed；The lower middle part upper end of core one is equipped with top Go out device one, backing-out punch one protrudes from the lower upper surface of core one, the external diameter of backing-out punch one, physical dimension and the bottom of shaped article to be processed Planar structure size is adapted, preforming spinning roller one on the first spinning roller axle and with a pair of the core fixture of first order teeth groove Should；Final shaping unit spinning roller one is on the second spinning roller axle and corresponding with the core fixture one of first order teeth groove；The knot of final shaping unit spinning roller one Structure is adapted with the first order teeth groove of shaping to be processed；

The core fixture two of spinning second level teeth groove is installed on spinning machine, core fixture two include upper core two, Lower core two；There are annular groove, the physical dimension of annular groove and the second level teeth groove of shaping to be processed in the lower end of upper core two Upper surface size is adapted, and the upper center of core two is equipped with alignment pin；There are forming blocks in lower core two, forming blocks upper surface has band to bore The inclined-plane of degree, it is adapted with the second level teeth groove lower end structure size of shaped article to be processed；Forming blocks center is equipped with backing-out punch Two, backing-out punch two protrudes from forming blocks, and the physical dimension of backing-out punch two and the baseplane physical dimension of shaped article to be processed are mutually fitted Match somebody with somebody, there is concave groove at the center of backing-out punch two, and the center concave groove of backing-out punch two is adapted with alignment pin；Preforming spinning roller two is mounted in first It is on spinning roller axle and corresponding with the core fixture two of second level teeth groove；Final shaping unit spinning roller two is mounted on the second spinning roller axle and and the second level The correspondence of core fixture two of teeth groove；The structure of final shaping unit spinning roller two is adapted with the second level teeth groove of shaping to be processed.

There is a through hole at the center of lower core one described in the utility model, and through hole is equipped with the push rod for being used for ejecting backing-out punch one, It is also convenient in spinning discharging air in processed product first order material simultaneously.

There is a through hole at lower core two described in the utility model and forming blocks center, and through hole, which is equipped with, to be used to eject backing-out punch two Push rod, while be also convenient in spinning discharging air in the material of the processed product second level.

The utility model spinning at twice, uses two work step rotary press modellings every time, to ensure teeth groove axiality up and down, most closes The positioning for being that each spinning selection of key.First time spinning is different from conventional folding wheel spinning, and no end face seam positions, So being positioned during spinning with the large end face internal diameter of the second level on mould, after rotary press modelling, material is filled up completely with upper and lower core During mould, the top lower core of circularity of first order teeth groove ensures, then by the use of be spun to come first order teeth groove as benchmark, the bottom of at Plane machining centre bore, such first order teeth groove are relatively good relative to the bounce of this datum hole.Then again with this centre bore Positioning, spinning second level teeth groove, so, bounce of the second level teeth groove for centre bore are also fine, so, the teeth groove of up/down steps Axiality be also to ensure that.In spinning twice, ensure that processed product material bottom surface is adjacent to mould, such two The secondary teeth groove come that is spun to will not become with respect to the position of baseplane, and installation dimension also can be good at ensureing.

The beneficial effects of the utility model are that solve teeth groove decentraction above and below different-diameter step spinning belt pulley to ask Topic, installation dimension instability problem, stable spinning production is realized, product quality is effectively ensured, there is provided qualified difference Diameter step formula plate spinning belt pulley.
