Description

The forming method of wheel
The present invention relates to the method with the various wheels of forming materials of rich plastic workings such as aluminium alloy or magnesium alloy, it is whole that the round plate of these wheels becomes with its peripheral rim part.
The wheels such as belt pulley that automotive wheels or belt transmission are used, its rim part outstanding with respect to the rectangular direction of round plate is integrally to be formed on the round plate periphery.
In wheel of the bus, in case in the periphery moulding of round plate the outstanding ware shape disk of annular wall, this annular wall is formed as the wheel rim section that is made of drop-center 23, inner rim 24 and outer rim 22 shown in Fig. 1 (a) and Fig. 1 (b).In belt pulley, in case after the plakea moulding, this annular wall is processed into the rim part of hanging belt.
Usually, this plakea is by forging molding, is shaped to plakea with the bulk material or the discoid material (hereinafter referred to as raw material) of light-alloy system through some forging process.
For example, the method that discloses in special fair 3-2574 number of Japanese patent gazette is to make plakea with forging, and part is a net shape beyond the annular wall of this plakea.Then, be processed into the wheel rim section with the annular wall of roll forming after with above-mentioned forging.
In this annular wall forming method in the past, the forging pressure when raw material are shaped to plakea is very big.Its reason be since plakea in the form of a ring wall from the round plate periphery to the outstanding shape of right angle orientation, in forging process, raw material must extend to annular wall agley from above-mentioned bottom in the metal pattern that moulding is used, therefore, when material extended, the moving resistance of material was very big.
Therefore, if want by a forging process raw material to be shaped to plakea, then forging pressure generation device and forging apparatus will be very big, and in order to bear above-mentioned forging pressure, forge the metal pattern of usefulness and also will do very greatly, but in fact do not do like this.Therefore, in order to reduce forging pressure, just this forging process was divided into some procedures in the past.After being divided into several operations like this, the degree of stretch in each operation reduces, and the forging pressure of each operation reduces, and forging apparatus also just can miniaturization.
But, so, just can be shaped to plakea through some procedures, so productivity is bad.Need be applicable to the metal pattern of each operation, extend simultaneously and be shaped to the required time of plakea from raw material, because losing if having time between each operation and must between each operation, transfer machined object.Therefore, just long when being molded over the round plate periphery and having the wheel of wheel rim from raw material to whole desired times of molding procedure with said method, so the productivity of wheel is poor.
The present invention makes in view of above-mentioned the problems of the prior art, its purpose is to provide a kind of wheel forming method, this method is compared with " by plasticity rapidoprint moulding rim part from the round plate periphery to the outstanding wheel of axis direction " method therefor in the past, can simplify operation from raw material to the wheel moulding, shorten the moulding required time, reduce metal pattern quantity.
To achieve these goals, the inventive method is that the plasticity rapidoprint is shaped to the wheel that rim part is given prominence to axis direction from the round plate periphery, it is characterized in that, form round plate by the pair of metal mould 301,302 that is provided with in opposite directions at axis direction pressurization raw material, simultaneously, above-mentioned raw material 10 extend along with above-mentioned pressurization, make material protrude in metal pattern peripheral border portion.By with above-mentioned two counterrotating roll assemblies of metal pattern, forming materials that this is outstanding is a rim part.
Above-mentioned method is undertaken by following step.
Raw material 10 are clipped between the metal pattern 301,302, by axis direction reciprocally the pressurized metal mould raw material 10 are extended.Along with the carrying out of pressurization, raw material 10 are extended and give prominence to from the metal pattern border to the outside.
Should give prominence to material by being shaped to respect to round plate 1 at the outstanding rim part of right angle orientation with above-mentioned two counterrotating roll assemblies of metal pattern.That is, when 301,302 rotations of pair of metal mould, roll assembly moves at the radial direction or the axis direction of its peripheral part along metal pattern.Or be fixed on and carry out above-mentioned moulding on the certain position.Otherwise when pair of metal mould 301,302 did not rotate, then roll assembly carried out above-mentioned moulding in this metal pattern periphery rotation.
When the processing and forming of this rim part, act on less the getting final product of pressure between the metal pattern 301,302.Only contact from the outstanding material of the outstanding ring-type of the boundary portion of above-mentioned pair of metal mould with roll assembly, and during by the forging molding wheel, the whole periphery of raw material extension contacts with the crimped section of metal die for moulding, so, with compare with the method for forging molding wheel, can reduce raw-material extension resistance significantly.
Among the present invention, be to have adopted one of pair of metal mould 301,302 or a succession of operation to form from raw material 10 to operation in the periphery formed rim portion of disk.So, compare with processing method in the past, can shorten from raw material 10 to the process time that is shaped to wheel, reduce metal pattern quantity simultaneously.Therefore, production performance improves than previous methods, can reduce the cost of manufacture of wheel.
