As can be seen here, the operation of existing type of production steel wheel is very numerous and diverse, and above-mentioned operation does not also comprise oneA little aided processes, just have more than twenties roads, and therefore its production efficiency is very low.
In addition, as shown in Figure 4, produce the steel vehicle wheel obtaining at wheel rim 1 and spoke according to above-mentioned operationBetween 2, there is weld seam 3, in addition, also there is the butt welded seam 4 after wheel rim butt welding, therefore this steel vehicle wheelBulk strength and rigidity be not fine, be easy to occur fatigue fracture at weld seam 3 and butt welded seam 4 places.
Based on this, be desirable to provide a kind of steel vehicle wheel forming method that significantly improves wheel production efficiency, andA kind of integral type shaped steel no-welding-seam wheel of being produced by this forming method is provided.
Summary of the invention
The object of the present invention is to provide a kind of integral type shaped steel no-welding-seam wheel forming method, it compares toExisting production method for wheel can significantly reduce manufacturing process, thereby greatly enhances productivity, and energyProduce that intensity is high, the wheel of good rigidly, long service life; In addition adopt the method to produceHigh-precision wheel, the wheel that adopts the method to produce, on its all stress surfaces, intensity equates and thicknessDifferent. In addition, the wheel that adopts the method to produce does not need to weld, and there is no weld seam.
To achieve these goals, the present invention proposes a kind of integral type shaped steel no-welding-seam wheel forming method,It comprises step:
(1) spreading: circle material is positioned in a spreading pattern, and the exterior contour of described spreading pattern is circleShape, adopts at least two symmetrically arranged roll milling wheels of the circumferencial direction along spreading pattern, leans in described spreadingIn mould, circle material is carried out to the synchronous spreading of plane, circle material is rolled into wheel blank; So-called plane spreading, isThe spreading track that refers to roll milling wheel is all the time in a plane, and so-called synchronous spreading refers at least two spreadingsThe spreading action of wheel is synchronous, thereby ensures the even by rollable surfaces quality of circle material, ensures circle material tableFace densification, therefore roll milling wheel is more, and circle expects that surperficial spreading vestige is just finer and close, and surface quality is just better,But the magnitude setting of roll milling wheel also needs to consider financial cost and stress factor;
(2) rim and spoke pre-profiling: adopt die mould punch and the die mould die axial direction at wheel blankOn exert pressure, with by just type of the rim and spoke of wheel blank press out type steel wheel;
(3) contour roll forming: wheel blank is positioned between contour roll forming punch and contour roll forming die, controls contour roll forming punchSynchronously rotate around its axle center with contour roll forming die, adopt one or several side pressure rollers at wheel blank simultaneouslyExert pressure to the first type part (being also the sidewall sections of wheel blank) of wheel rim of pre-profiling in the radial directionWith by extruding to wheel rim just type part carry out further precise forming, described side pressure roller is being exerted pressureSimultaneously also around himself axle center rotation;

Correspondingly, the present invention also provides the above-mentioned integral type shaped steel of a kind of employing no-welding-seam wheel forming methodThe integral type shaped steel no-welding-seam wheel making.
Further, the material of integral type shaped steel no-welding-seam wheel of the present invention is carbon steel, aluminium, magnesiumAluminium alloy or stainless steel.
Integral type shaped steel no-welding-seam wheel forming method of the present invention is that one is different from existing type completelyThe production technology of steel wheel manufacture method, as described in the background technology of this case, existing steel vehicle wheel manufacturerMethod is first to produce respectively wheel rim and spoke, then wheel rim and spoke is synthesized together, thereby has made welderingThe steel vehicle wheel of seam. And the technical program has adopted integrated technique, itself and prior art are completely notWith, it is mainly reflected in:
(1) in the forming process of integral type shaped steel no-welding-seam wheel, adopted in a creative way calendering forming workSkill, this calendering forming technique is plane calendering forming, roll milling wheel is except rotation, only at spreading patternHorizontal plane upper feeding, simultaneously spreading pattern is to the material power that imposes restriction, material is by roll milling wheel and spreadingThe interaction force of pattern and being out of shape, therefore the upper surface of material and lower surface all deform. Adopt and roll overThe Workpiece structure that compression technology is produced is tightr, and intensity is higher, and weight is lighter, and material consumption is lower. In addition,Adopt calendering forming technique, workpiece is stressed large, in forming process because spreading pattern is to workpiece deformation toolRestricted effect and produce deformation drag, impels workpiece blank to be squeezed, therefore the distortion of workpiece blankMore accurate. In addition, adopt calendering forming technique can make the bending of the workpiece that commaterial produces tiredThe labor life-span improves greatly. Adopt calendering forming technique, the restricted scope of molding mode of workpiece is large, belongs toForce moulding, therefore can be according to how much of the various progressively distortion of the shape precise forming of spreading pattern cavityCross section, after moulding, quality balance, dynamic balance accuracy axial and circumferencial direction are high. Further, by adoptingCalendering forming technique can spreading go out equal strength wheel (intensity that is all stress surfaces of wheel all equates,Meet requirement of strength), this equal strength wheel is uniform thickness wheel not, the stressed of the each stress point of wheel can rootThe thickness that changes material according to demand is different, material thickness just can be reduced in for example stressed little position, fromAnd minimizing materials, and this not uniform thickness wheel adopts existing manufacture method to produce, onlyThere is the method adopting described in the technical program, because first circle material is moulding in spreading pattern, therefore canTo design spreading pattern correspondingly according to the force request of wheel. And no matter prior art is to produce wheelRim, still produces spoke, and it all adopts the mode of production of Pressing Deformation, in the process of Pressing Deformation,Pattern chamber is open, and it does not have to material the power of obligating, and only makes workpiece bending, and it only changesThe shape of workpiece, and can not change the shape of workpiece section. In addition, because the spreading angle of roll milling wheel is little,Therefore the active force of roll milling wheel will be far longer than the active force in punch forming unit are, thereby makes to roll overPinch roller once just can complete the distortion of workpiece, and punching press can not complete the thickness deformation of workpiece.
(2) adopted compound die mould (being rim and spoke pre-profiling) technique, and directly from blank, extrudedThe just type of rim and spoke of integral type steel vehicle wheel.
(3) employing contour roll forming technique further completes the distortion of wheel rim, thereby directly from integral type steel vehicle wheelRim and spoke just the further precise forming of type go out the wheel rim part of steel vehicle wheel, thereby completed manufacture nothingThe committed step of weld seam steel vehicle wheel, this contour roll forming processing step is to carry out within the scope of the plastic deformation of materialProgressively cold rolling, cold extrusion shaped and flexural deformation lentamente, molds high-intensity wheel rim section, at thisThe R turning thickening gradually of wheel rim in process, with the junction of spoke also thickening gradually, through this contour roll formingThe wheel rim girth of step moulding should be greater than the girth 10-15mm of standard finished products, is beneficial to adding of next stepWork operation, the inner surface of wheel rim meets the world, domestic standard and the geometric accuracy of tire in conjunction with section,Thereby ensure bond strength and the frictional force of wheel rim and tire. It should be noted that, as spreading pattern,The technical program does not limit the concrete shape of contour roll forming punch, contour roll forming die and side pressure roller, this technologyThe key of scheme is this molding mode, and those skilled in the art should be according to actual productThe outline that need to design side pressure roller, thereby form satisfactory wheel rim shape.
(4) compression, pressing and finishing complete in a procedure, thereby ensure the relative of wheel rim and spokePosition and offset distance, guarantee normal diameter and the beat requirement of wheel rim.
As can be seen here, the production process of integral type shaped steel no-welding-seam wheel forming method of the present invention is far awayFar fewer than existing steel vehicle wheel manufacture method, therefore adopt the forming method of the present invention can be significantlyEnhance productivity.
In addition because having adopted, integral type shaped steel no-welding-seam wheel forming method of the present invention is rolled into,Type and contour roll forming technique, realized the production process of steel vehicle wheel one-body molded, and without butt welding, because ofThis has improved rigidity, intensity and the life-span of wheel greatly. In addition omitted also corresponding release of butt welding stepThe devices consume of relevant butt welding equipment, air intake device etc. and power consumption, also avoided welding to causeThe pollution that splash, smog etc. brought to environment.
Equally, the integral type that adopts integral type shaped steel no-welding-seam wheel forming method of the present invention to manufactureShaped steel no-welding-seam wheel with by welding compared with synthetic steel vehicle wheel, it does not have weld seam, security is better.
Adopt integral type shaped steel that integral type shaped steel no-welding-seam wheel forming method of the present invention manufactures withoutWeld seam wheel can be for passenger car, also can be for commercial car.
