Description
Technical field
The utility model relates to roller carrier shaft processing technique field, is specially a kind of crowded axle machine.
Background technology
The two ends of roller carrier shaft need install bearing additional, so just the two ends diameter of axle with the roller carrier shaft of the plus tolerance diameter of axle need to be narrowed down to the standard diameter of axle.Usual way is to adopt drawbench at present, or processes on lathe, and not only complicated operation, and process velocity is slow, and processing cost is high.
Summary of the invention
There is processed complex, speed is slow, cost is high problem in order to solve at present for roller carrier shaft two ends undergauge processing in the utility model, a kind of crowded axle machine is provided.
The utility model is to adopt following technical scheme to realize:
A crowded axle machine, comprises frame, and in described frame, level is fixed with extrusion oil cylinder, and the piston rod end of described extrusion oil cylinder is fixed with and is extruded shaft end and can be extruded the extrusion die stretching into.
Described extrusion die comprises overcoat, in described overcoat, interval is fixed with in coaxial front mould and rear mold, the inner wall shape of described front mould and rear mold is: along being extruded shaft end, stretching into direction and comprise successively open top extruding conical surface A, moulding anchor ring B, open top outlet conical surface C inwardly inwardly, between described extruding conical surface A, moulding anchor ring B, outlet conical surface C, for round-corner transition is connected, after the variation tendency of described front mould and rear mold internal diameter is from large to small, change from small to big again; The standard diameter of axle that the internal diameter e of the moulding anchor ring B of described front mould is squeezed last item, the internal diameter f of the moulding anchor ring B of described rear mold is the little 0.2～0.5mm of the standard diameter of axle than squeezed last item.
In described frame, be also provided with and will be extruded the clamp mechanism of axis clamping.
After squeezed last item is clamped, one end of squeezed last item is resisted against on support, and extrusion die is under the motion of extrusion oil cylinder, and the other end with the squeezed last item of the plus tolerance diameter of axle is just in time squeezed in extrusion die and successively by front mould and rear mold in extrusion die.
During work, clamp mechanism is easy to realize, and the mode of clamping is varied.Utilize the thrust of extrusion oil cylinder, the end of roller carrier shaft is squeezed in extrusion die, first pass through front mould, the diameter of axle extruding with the roller carrier shaft of the plus tolerance diameter of axle is contracted to the standard diameter of axle, and then pass through rear mold, the end diameter of axle of roller carrier shaft is further dwindled to 0.2～0.5mm, the roller carrier shaft being extruded after undergauge becomes shape as shown in Figure 4, meet bearings mounted requirement, front mould makes the end diameter of axle of roller carrier shaft reach the standard diameter of axle, and rear mold makes the end diameter of axle of roller carrier shaft reach fitting tight size.Wherein, the front mould in extrusion die and the spacing distance between rear mold require to determine according to real work, for example, between 8～12mm.
In addition; the inclined degree of extruding conical surface A in described front mould and rear mold; be that the size of angle (importing angle) of cone element and axis and the size of extrusion oil cylinder thrust have direct relation; import the excessive easy damage front mould in angle or rear mold; import the too small thrust that needs extrusion oil cylinder huge that causes in angle; therefore the present invention is after great many of experiments; preferably importing angle is arctan1/5～arctan1/7; be roller carrier shaft end in through extruding conical surface A process, its radially the ratio of undergauge stroke and axial stroke be 1:5～1:7.For example, the roller carrier shaft that the processing diameter of axle is 20mm, the thrust that needs extrusion oil cylinder is 5t; The roller carrier shaft that the processing diameter of axle is 25mm, the thrust that needs extrusion oil cylinder is 8t; The roller carrier shaft that the processing diameter of axle is 30mm, the thrust that needs extrusion oil cylinder is 12t.Preferably, clamp mechanism equals the thrust of extrusion oil cylinder to the clamping force of roller carrier shaft, prevents that roller carrier shaft is extruded and occurs bending.
Advantage of the present utility model is as follows:
1, increase work efficiency, than machine tooling, improve 3 times; Than cold-drawn axle, improve 2 times.
2, reduce by 2 times of labour intensity.
3, cost-saving, by 20,000 calculating of annual production, expenses of labour saves 100,000, and fee of material saves 40,000.
4, reduce raw material and drop into 10%.
The utility model is reasonable in design, simple in structure, has solved at present for roller carrier shaft two ends undergauge processing and has had that processed complex, speed are slow, high in cost of production problem.
