The present invention is the manufacture method of the relevant automobile of being made by aluminium alloy, magnesium alloy etc. with light alloy wheel, particularly about its roker by on the excircle of the spoke card made of requirement shape, along axletree to the wheel rim of two side-prominent inside and outside both sides and the manufacture method that the spoke card is made unitary whole forging type light alloy wheel.
In light alloy wheel manufacture method such as the automobile of making by aluminium alloy and magnesium alloy etc., the spoke card with at its excircle upper edge axletree to manufacture method from unitary whole formula light alloy wheel to two side-prominent inside and outside both sides wheel rims that make, published in the Japan Patent spy and opened on the clear 56-26648 communique.
At this, introduce by accompanying drawing and to make above-mentioned spoke card and wheel rim is made unitary whole forging type light alloy wheel, the general in the past method that adopts.
Past, when making this wheel, the light-alloy blank (1) that has adopted the round bar made of method with continuous casting to cut off by Len req, through forging this light-alloy blank (1) is made as shown in figure 15 on the excircle of circular spoke card (11), flange (2) (3) along axletree to the goods that become approximate H type to two side-prominent sections, simultaneously, on above-mentioned spoke card (11), make the spoke dish required form that constitutes by the roker (14) of heavy wall and the thinner wall section (15) between these rokers (14).Then, for on the excircle of the spoke card of making like this (11), make outside wheel rim (12) by the flange (2) that shape shown in the chain-dotted line on this figure will be given prominence to laterally, will be by shown in Figure 16, be equipped with axle (20) in the inboard of spoke card (11), be equipped with top rod (21) in the outside of spoke card (11), clamp above-mentioned spoke card (11) with this axle (20) and top rod (21), keep revolution along with axle (20) revolution makes light-alloy blank (1); Meanwhile, at the outer circumferential sides of above-mentioned flange (2) a pair of stairstepping roller roller of relative configuration with inner circumferential side (22) (23), flange (2) is clipped between roller roller (22) and (23), by above-mentioned axle light-alloy blank (1) is turned round usually with 300~400 rev/mins speed, move aforementioned roller roller (22) (23) simultaneously, make outboard flanges (2) distortion, be configured as the outside wheel rim (12) of the shape that requires.
In addition, after outside wheel rim (12) is shaped, for making flange (3) outstanding to the inside on spoke card (11) excircle be configured as the inboard wheel rim (13) shown in Figure 15 chain-dotted line, as shown in figure 17, the axle (31) that has the cylindrical shape corresponding in the configuration of the inboard of spoke card (11) with inboard wheel rim (13) shape, dispose hold down mandrel (32) in the outside of spoke card (11) simultaneously, spoke card (11) is clipped between the above-mentioned axle (31) (32), light-alloy blank (1) is turned round with axle (31) (32); As shown in the drawing such, make the calendar rollers roller (33) that is configured in medial flange (3) outer circumferential sides, be pressed on this flange (3) and go up and move along inboard axle (31), make this flange (3) be configured as inboard wheel rim (13) by desired shape.
Then, can be by carrying out Punching Technology with punch press, carry out machining with lathe, carry out methods such as End Milling Process with milling machine, above-mentioned spoke card (11) is gone up between roker (14) unwanted thinner wall section (15) remove, so just can require on spoke card (11) excircle of spoke shape with having, make the unitary whole light alloy wheel along axletree to two side-prominent wheel rims (12) (13) and create.
But, in this class wheel, corner angle α by the flange of the outside wheel rim (12) of formation flange on the excircle of spoke card (11) is generally 65~80 degree, when adopting conventional method that it is shaped, if accelerate to be pressed on the translational speed of the above-mentioned rollers roller (22) (23) on the outboard flanges (2) to shorten its curring time, will impose severe pressure to these roller rollers (22) (23) and flange (2), and make their damaged and cause problems such as outside wheel rim (12) is serious out of shape thereby produce; On the contrary, if reduce the translational speed of these roller rollers (22) (23), then exist the shaping of outside wheel rim (12) just to need the problem of more time.In addition, the flange (2) of the light-alloy blank (1) that will turn round like this is clamped between roller roller (22) and (23) and makes its when distortion, produce distortion owing to reasons such as rotating vibration can make outside wheel rim (12), thereby reduced the circularity of wheel rim (12); For example: diameter is 15 inches a wheel, can produce the error of 2.5~3mm on its diameter, also has problems such as outside wheel rim (12) can't correctly be shaped.
In addition, in the process of inboard wheel rim (13) that is shaped, the employed in the past axle (31) (32) of clamping spoke card (11), its each end face slightly becomes flat condition, when manufacturing has the wheel of smooth spoke card (11) shown in Figure 13, can not produce special problem; But, the wheel that need have different shape spoke card (11) now, make constitute spoke card (11) shape as shown in Figure 14 roker (14) at axletree to being bigger bending, when spoke card (11) is concavo-convex wheel, come the concavo-convex spoke card (11) of clamping if use the smooth axle of end face (31) (32) as before, make light-alloy blank (1) revolution, use the be shaped words of inboard wheel rim (13) of calendar rollers roller (33) again, then because the flywheel moment of light-alloy blank (1) and the effect of calendar rollers roller (33) thrust, roker (14) produces distortion can resembling among Figure 18 shown in the chain-dotted line, the problem of spoke card (11) shape modification occurs making.Also have, with above-mentioned the sort of calendar rollers roller (33) press flange (3), when inboard axle (31) is rolled this flange (3), if the flange that had rolled (3) contacts with the stage portion (31a) of axle (31), after this calendering has just become difficulty, and the ora terminalis that inboard wheel rim (13) can occur is the problem of flange fully.
Moreover, when carrying out Punching Technology with general punch press removing that spoke card (11) goes up unwanted thinner wall section (15) between the roker (14), must prepare many punch dies for the shape that adapts to spoke card (11), will pay higher expense for punch die like this; Simultaneously, for the spoke card (11) with complicated shape and above-mentioned the sort of spoke card (11) person that is the bending, die-cut its thinner wall section (15) will be very difficult.Also have, carry out machining and carry out vertical milling with milling machine and cut the poor in processability that adds man-hour, particularly carry out vertical milling and cut and add man-hour, mill many holes owing to will bore with milling machine with lathe, therefore very time-consuming; Moreover, adopt this processing method to also have the big problem of waste of material.
The present invention uses in the light alloy wheel process with the wheel rim formation unitary whole forging type automobile on its excircle in the light-alloy blank that adopts aluminium alloy and magnesium alloy etc. to make, manufacturing spoke card, has solved the problems referred to above.

Introduce the blank made from light-alloys such as reflectals in detail by accompanying drawing below, make the embodiments of the invention that the solid forging type automobile that spoke card and wheel rim are become one is used light alloy wheel.
In the present embodiment, usually with light alloy materials such as aluminium alloy that casts the long size cylindrical shape of making continuously and magnesium alloys, by the blank of Len req cut-out becoming light-alloy blank (1) as the usefulness that makes wheels; Again by as shown in Figure 1, with this light-alloy blank (1) be placed on by press forming between the upper and lower mould (41) (42) made of requirement shape; On spoke card (11), make when the institute that is made of the roker (14) of heavy wall and the thinner wall section (15) between these rokers (14) requires the shape of spoke dish, make on this spoke card (11) excircle to the outstanding outside wheel rim (12) in the axletree outside and the shape of above-mentioned spoke card (11) to be shaped simultaneously.
In addition, making outside wheel rim (12) is aforesaid 65~80 degree from the step angle of the excircle flange of spoke card (11); Because light-alloy blank (1) need stand bigger distortion, therefore when carrying out die forging, generally to heat light-alloy blank (1) earlier with aforementioned upper and lower mould (41) (42), again it is carried out hot forging; In addition, when carrying out this hot forging, use several patrixes (41) and counterdie (42) usually, these upper and lower moulds of conversion (41) (42) progressively are out of shape light-alloy blank (1) in turn, form outside wheel rim (12).When carrying out such die forging, in the present embodiment, as shown in Figure 2, top along continuous straight runs at pressure apparatus (40) is provided with guide rail (43), simultaneously, in that being housed, shifting roller (44) can below the erecting bed (45) that this guide rail (43) moves, multiple patrix (41) (having 2 kinds in the example shown in Figure 2) be housed, be located at hydraulic cylinder (46) on the guide rail (43) and drive this erecting bed (45) and move it, so that can change patrix (41).Then, make the positioning key that is located on the pressure apparatus (40) and open on erecting bed (45) first and be connected groove (48a) and cooperate, the position of counterdie (42) top that the fixed position of erecting bed (45) should make first patrix (41) just in time be in to be fixed on the base (49); Then, make positioning key (47) be connected groove (48b) with second of erecting bed (45) again and cooperate, the fixed position of erecting bed (45) should make the 3rd patrix (41) just in time be in place, counterdie (42) top position.Like this, when changing patrix (41), when light-alloy blank (1) being carried out hot forging with first patrix and second patrix, can change patrix (41) at short notice, and change patrix at every turn and all needn't heat once more light-alloy blank (1), realized continuous die forging to light-alloy blank (1).
In addition, the shape that spoke card (1) is shaped is to be determined by the shape of scribing on the upper and lower mould that uses in the finish-forging operation (41) (42), therefore the spoke card can be by all latticed, shown in Figure 4 arbitrary shapes such as simple pattern shapings spoke-like and shown in Figure 5 as shown in Figure 3; And the shape of this spoke card (11) is not limited only to even shape shown in Figure 6, even the roker of the sort of formation shape shown in Figure 7 (14) also is easy to be shaped to having than macrobending, spoke card with concaveconvex shape at axletree.
After the shape and outside wheel rim (12) shaping of spoke card (11), make axletree outstanding to the inside flange (3) in spoke card (11) excircle upper edge be configured as the inboard wheel rim (13) of the shape that requires through rolling and processing more like this.
In addition, the situation of the inboard wheel rim of shaping (13) is identical with traditional situation on the excircle of the spoke card (11) that the roker bending is less, shape is smooth on the sort of spoke card shown in Figure 6 (11); As shown in figure 17, fit over the inboard of spoke card (11) with axle (31) with outer circumferential shape corresponding with the shape of the inboard wheel rim (13) that is shaped, fit over the outside of spoke card (11) with hold down mandrel (32), spoke card (11) is clamped between slightly smooth this center roller (31) (32) of end face, by motor-driven speed change gear these axles (31) (32) are turned round usually with 300~400 rev/mins speed with light-alloy blank (1), control the calendar rollers roller (33) that is configured in medial flange (3) outer circumferential sides with modes such as electro-hydraulic servo or hydraulic servos again, the inboard flange (3) of light-alloy blank (1) with this calendar rollers roller (33) roll extrusion is being turned round rolls this flange (3) by inboard axle (31).
But, when require roker (14) in the sort of formation spoke card shown in Figure 7 (11) at axletree to having than macrobending, have when being shaped inboard wheel rim on spoke card (11) excircle of concaveconvex shape, if still adopt a more smooth center roller (31) (32) the clamping spoke card (11) of above-mentioned end face nearside wheel rim (3) is carried out rolling and processing, then the shape of spoke card (11) can produce distortion the situation that will often run into as the past, therefore in the embodiment shown in fig. 8, adopted the end surface shape axle (31) (32) corresponding with spoke card (11) concaveconvex shape, the end face of these axles with concaveconvex shape (31) (32) can be coincide with the concaveconvex shape of spoke card (11), spoke card (11) is clipped between these axles (31) (32).In this case, as previously mentioned, make light-alloy blank (1), use calendar rollers roller (33) that the flange (3) of inboard is rolled again with these axles (31) (32) revolution.In this case, although on spoke card (11), applied the flywheel moment of light-alloy blank (1) and by the formed moment of torsion of thrust of calendar rollers roller (33), owing to adopted the on all four axle of concaveconvex shape (31) (32) of end face and spoke card (11), also can suppress the distortion of spoke card (11) effectively.In addition, in this embodiment, though when only having enumerated on the excircle of spoke card (11) rolling and processing medial flange (3) and adopted the example of an end surface shape center roller (31) (32) corresponding with spoke card (11) concaveconvex shape with concaveconvex shape, yet, as in the past, on the excircle of spoke card (11) during rolling and processing outside wheel rim (12), in spoke card (11) is under the situation of concaveconvex shape, to suppress the distortion of spoke card (11) shape, also is possible certainly with this axle (31) (32) clamping spoke card (11).
In addition, as mentioned above, spoke card (11) is clamped between the axle (31) (32), light-alloy blank (1) is turned round with these axles (31) (32), along inboard axle (31) medial flange (3) on spoke card (11) excircle is carried out rolling and processing when making it be configured as inboard wheel rim with calendar rollers roller (33), flange after the calendering (3) can contact with the stage portion (31a) of axle (31), can't carry out the later calendering processing of flange to flange (3), therefore the flange of inboard wheel rim (13) ora terminalis can't form.In this case, in the present embodiment, after with calendar rollers roller (33) flange (3) being carried out to a certain degree calendering, as shown in Figure 9, with upper and lower mould (51) (52) end of the flange (3) after this calendering is outwards expanded with expansion again, the end of flange (3) is shaped under the state of the stage portion that surmounts axle (31) (31a).Then, after the end of flange (3) is extended like this, press as shown in Figure 10 again, once more spoke card (11) is clamped between the axle (31) (32), make light-alloy blank (1) revolution, flange (3) after will expanding with calendar rollers roller (33) is pressed on the inboard axle (31), makes it be configured as the inboard wheel rim of end flange.In addition, in example shown in Figure 10, the calendar rollers roller (33) that inboard wheel rim (13) is shaped that adopts, have a groove (33b) in the centre of its roll surface (33a), utilize the groove (33b) of this roller roller (33), requiring outside the position of outboard wheel rim (12) and inboard wheel rim (13), process edge strip (12a) that fixedly tire separately uses (13a) along circumference.
After inboard wheel rim (13) is shaped, the unwanted thinner wall section (15) that will be present between the roker (14) of spoke card (11) is removed, just make as Figure 13 and spoke card shown in Figure 14 (11) and wheel rim (12) (13) formation unitary whole formula light alloy wheel.
In addition, when excision thinner wall section (15), in the present embodiment, as shown in figure 11, the light-alloy blank (1) that above-mentioned inboard wheel rim (13) has been shaped is stated from the turntable (63) by required several definite position holder, and this turntable (63) is being supported with freely rotating by the roller (62) that is located at supporting leg (61) upper end; Meanwhile, predetermined job area is remembered among operation certain part with the memory of robot (66), and the nozzle (65) of winding-up plasma arc just is installed in the front end of this robot motion arm (64); By instruction, make action arm (64) action of this operation, with moving nozzle (65) with robot (66) from this part of memory; Utilization as shown in Figure 12, is excised unwanted thinner wall section (15) and make its formation opening by the plasma arc of nozzle (65) ejection.Therefore, even to complex-shaped person of spoke card (11) and spoke card (11) incliner, also can not cause the distortion of its shape, the processing that makes unwanted thinner wall section (15) form opening can be carried out simply.Here, when adopting this plasma arc to cut, when generally selecting the 148A(striking for use 29~30A) electric current, the speed of cutting processing is 2m/min, adopts 6kgf/cm 2Compressed air use gas as cutting.
In addition, this processing that makes thinner wall section (15) form opening not necessarily must just can be carried out after inboard wheel rim (13) is shaped, and also can carry out before inboard wheel rim (13) is shaped.
As above detailed introduction, the manufacture method of light alloy wheel involved in the present invention, on making spoke card and excircle thereof, during along axletree to the solid forging light alloy wheel that is integrated to two side-prominent inside and outside both sides wheel rims, made by aluminium alloy, magnesium alloy etc., can use die forging Make on the spoke card excircle to be shaped simultaneously with the outside wheel rim of sharp-pointed corner angle flange and the shape of spoke card laterally, and outside wheel rim is shaped at short notice very simply, can realize the high and correct shaping of circularity precision simultaneously. In addition, in this die forging, when heating light-alloy blank makes blank deformation successively with several patrixes and counterdie again, top at pressure apparatus is provided with guide rail, under the erecting bed that can move along this guide rail multiple patrix is housed, and erecting bed is moved along guide rail, change in turn patrix, thereby can realize at short notice the replacing of patrix, each die change needn't heat again to the light-alloy blank, has realized continuous die forging.
In addition, the present invention is after adopting above-mentioned die forging that outside wheel rim and spoke card shape are shaped simultaneously, adopt a center roller clamping wheel spoke card, the light-alloy blank is turned round with axle, again with the calendar rollers roller along the outer circumference surface of inboard axle on the spoke card excircle to the inside outstanding flange roll and the embark on journey inboard wheel rim of requirement shape of rolling and processing; When the roker that consists of spoke card shape has when being concaveconvex shape along the wheel axial bending, in a center roller of clamping spoke card, the part that is pressed in the end face on the spoke card or the integral body that have an axle at least, its shape should be made the shape corresponding with spoke card concaveconvex shape, and the end face of this axle can be coincide with the concaveconvex shape of spoke card; With a center roller clamping wheel spoke card, though on the excircle of the spoke card with concaveconvex shape the inboard wheel rim of rolling and processing, can prevent that also the concaveconvex shape of spoke card from producing distortion.
