The specific embodiment
Contrast accompanying drawing below, the description by optimum embodiment, is described in further detail the specific embodiment of the present invention.
The manufacture method of this major diameter folding platform web wheel, comprises following technological process: heating process-die forging operation-rolling process-press-bending operation before saw blank process-forging, wherein,
Die forging operation, become to suppress on parison the folding platform of wheel web, and metal sendout is reasonable inside and outside the preformed stage makes to roll over platform during wheel moulding;
Rolling process, reduce disc roller head length, the profile of disc roll is shifted to an earlier date and increased the diameter of disc roll to roller head direction, make the profile position of disc roll go deep into disc groove and touch disc surface, while making the rolling of disc roll, do not produce and interfere with folding platform position; A reserved Non-contact angle between the aperture surface of wheel and the profile of disc roll;
Press-bending operation, the mode that adopts bending die laminating to roll over platform concave side disc, single side face location bending die, bending die leaves space near folding platform place.
Further, die forging operation, in the preformed stage, the amount of metal in territory, doubling platform stagnant zone supplements, and adds big hub and the outer metal discharge rate of compacting disc, makes to roll over the inside and outside metal sendout of platform reasonable.
Noncontact angle between the profile of the aperture surface of wheel and disc roll is greater than 0 degree, noncontact angle can prevent that die forging operation metal from arranging the wheel that difficulty is large outward, the stage of rolling produces steel-fastening because the circumferential amount of metal of wheel rim is inhomogeneous, to cause milling train to rise, and guarantees crudy.But this angle is excessive, and can to cause again disc roller and wheel blank to work while rolling contact area too small and cannot drive wheel blank rotation, so 1-4 degree is generally got at noncontact angle.
Now by reference to the accompanying drawings major diameter is rolled over the manufacture method of platform web wheel, be specifically described.
Roll over as seen from Figure 1 platform web wheel and in its disc stage casing, have a folding platform.The disc center line of conventional wheel is level and smooth coherent, and its disc center line of folding platform web wheel exists drop △.Conventional wheel rolling method cannot adapt to the production of this type of wheel, and especially, when wheel diameter D surpasses 1000mm, wheel resistance of deformation is large, production difficulty aggravation.
Existing mill for rolling center disctype wheels can only rolling uniform thickness web wheel when producing wheel or thickness all become web wheel, disc center line is straight line.Therefore folding platform web wheel of the present invention is as according to common milling method, its rolled blank shape as shown in Figure 3, the rolling of base shape is convenient, but must when bending, to disc folding platform region, carry out drop stamping and can form folding platform, during press-bending, disc produces the potential risk maximum of drawing crack, for wheel, can produce potential operation risk.Disc surplus is inhomogeneous in addition, and lumber recovery is low.
Therefore, before the present invention considers that the formation step of folding platform is mentioned to rolling, when forging stage wheel moulding, directly will roll over platform and suppress out.But the position of folding platform is generally positioned at disc stage casing, is also that common of wheel rolls position, the difficulty such as therefore folding platform is shifted to an earlier date in the time of must causing wheel rolling after compressing, hole enlargement amount reduces, roll space is little, wheel rim and wheel rim are difficult for being full of.
Therefore the present invention considers to avoid this folding platform region when wheel rolling, roll out the shape of base shown in Fig. 2, and after difficult point is to have avoided folding platform region, rolling hole enlargement amount L significantly reduces, and rolling time is short, and wheel rim position is difficult for being full of.One-tenth parison as shown in Fig. 4 (2) is placed the insufficient space of conventional disc roll in addition, can produce and interfere with folding platform region.
Therefore in the manufacture method that the present invention adopts, disc roll is improved, as shown in Fig. 4 (1), reduce disc roller head length, allow the profile position of disc roll to roller head direction, shift to an earlier date and to strengthen disc roller diameter as far as possible, make disc roll profile position can go deep into disc groove and touch disc surface, during the rolling of disc roll, do not produce and interfere with folding platform position; Become parison internal diameter angle to be less than corresponding disc roller angle, the disc roll open rolling stage not exclusively fits, and plays and slows down the object that disc increases, preferentially tread wheel rim is full of.In addition, in order to guarantee the degree of filling in little hole enlargement amount lower rim, between the aperture surface of wheel and disc roll profile, reserved a Non-contact angle α, α is greater than 0 degree; At disc roll, rise while rolling, due to the existence of Non-contact angle α, wheel rim metal flow is reduced to the amount of disc, delayed rolling time, the rolling number of revolutions of wheel in milling train increased, be convenient to being full of of wheel rim.
It is more difficult that the existence of disc folding platform also makes into parison metal flow in compacting deformation process, therefore in the preformed stage, guarantee that the metal sendout inside and outside folding platform is reasonable, otherwise there will be disc blocked up and wheel rim metal deficiency or wheel rim to cross to be full of and disc folding platform place is not fully filled.By Marc, carry out finite element deformation simulative, shown in Fig. 6, if employing common metal pre-distribution scheme, excessive effectively outer row of wheel hub and the outer metal of compacting disc, wheel rim degree of filling is bad, and especially the territory, metal stagnant zone at disc folding platform place also exists not full state.And improved metal pre-distribution scheme shown in employing Fig. 5, by bottom die being made to double-deck boss, add big hub and the outer metal discharge rate of compacting disc, and territory, doubling platform stagnant zone carries out metal and supplement, the degree of filling of wheel hub, disc and wheel rim is guaranteed simultaneously.
Separately in press-bending operation, through the improvement in die forging operation, there is not disc drawing crack risk, therefore emphasis solves the depth of parallelism problem of the inside and outside two sections of disc of folding platform, consider the particularity of this disc shape, bending die adopts the mode of laminating folding platform concave side disc, simultaneously in order to take into account the impact of wheel eccentricities doubling platform position, the location of bending die adopts single side face locate mode, only near folding platform place, is staying a small amount of space to prevent that mould doubling platform from producing pressure and collapsing.
The manufacture method of this major diameter folding platform web wheel, the potential risk of having avoided conventional wheel rolling method to produce this type of folding platform web wheel, has improved metal lumber recovery and production efficiency, realizes the stable and batch production of this type of wheel.
