Definitions
- the invention relates to a method for manufacturing an automobile accessory, in particular to a method for manufacturing a plate-free welded wheel.
- the existing method for manufacturing a plate wheel is to separately manufacture the rim and the spoke, and then synthesize and weld the manufactured rim and spoke to form a wheel.
- the specific process flow includes:
- Production rim R-1 unwinding; R-2 flattening; R-3 butt welding; R-4 circle round; R-5 butt welding; R-6 scraping slag; R-7 end cutting; R-8, 9, 10 three-step cold rolling forming; R-11 expansion sizing; R-12 punching door hole.

- the object of the present invention is to provide a method for forming a one-piece sheet weldless wheel, which is compared with
- the traditional wheel manufacturing method can greatly reduce the manufacturing process, thereby greatly improving the production efficiency, and can produce wheels with high strength, good rigidity and long service life; in addition, the method can also produce high-precision wheels, which are produced by the method. Out of the wheel, all the forces on the surface are equal in strength and different in thickness. In addition, the wheels produced by this method do not need to be welded, there is no weld, they will not leak, and airtightness detection is not required.
- the present invention provides an integrated sheet weldless wheel forming method comprising the steps of:
- the plane is synchronously pressed in the rolling profile to press the round material into a wheel blank;
- the so-called plane rolling means that the rolling track of the rolling wheel is always in one plane,
- so-called synchronous ⁇ Pressure means that the rolling action of at least two rolling wheels is synchronized, so as to ensure the uniform quality of the pressed surface of the round material and ensure the surface of the round material is dense, so the more the rolling wheel, the rolling marks on the surface of the round material The denser the surface, the better the surface quality, but the number of rolling wheels needs to take into account economic costs and stress factors;
- Roll type Roll type: the wheel blank is positioned between the roll type punch and the roll type die and pressed, and the roll type punch and the roll type die are controlled to rotate synchronously around the axis thereof, and one or both are used.
- a plurality of side pressure rollers apply pressure to the initially formed rim profiling portion (i.e., the side wall portion of the wheel blank) in a radial direction of the wheel blank to further precisely shape the rim profiling portion by pressing, The side pressure roller also rotates around its own axis while applying pressure;
- the blank passing through the rolling step is positioned between the shaping punch and the shaping die, and the shaping punch and the shaping die apply pressure in the axial direction of the wheel blank, and the shaping side pressing die is used. Pressure is applied to the rim priming portion of the blank in the radial direction of the entire circumference of the wheel blank to simultaneously flatten, compress and finish to form a one-piece sheet weldless wheel.
- the rolling step in the method for forming a one-piece sheet weldless wheel according to the present invention is preferably a planar synchronous misalignment rolling.
- the so-called misalignment pressure means that the setting of each of the rolling wheels in the initial position is offset from each other, so that the rolling tracks of the rolling wheels on the surface of the round material do not coincide, so that the surface of the round material is more dense.
- the method for forming a one-piece sheet weldless wheel according to the present invention further comprises the steps of: stepping the lower round material and punching a positioning hole on the round material before the step (1), the positioning hole is used for the round material Stable placed in the rolling mold.

- the technical solution adopts an integrated molding process, which is completely different from the prior art, and is mainly embodied in:
- the rolling forming process is pioneered in the forming process of the one-piece sheet non-weld wheel.
- the rolling forming process is flat rolling forming, and the rolling wheel is only in the pressing mode except for the rotation.
- the horizontal plane feeds, while the pressing master applies a binding force to the material, and the material is deformed by the interaction force of the rolling wheel and the pressing master, so that both the upper surface and the lower surface of the material are deformed.
- the workpiece produced by the rolling process has a tighter structure, higher strength, lighter weight and lower material consumption.
- the rolling forming process by adopting the rolling forming process, the workpiece is subjected to a large force, and deformation resistance is generated due to the restriction of the pressing of the pressing form on the workpiece during the forming process, and the workpiece blank is pressed, so that the deformation of the workpiece blank is more accurate.

- the force can change the thickness of the material according to the demand.
- the position of the small force can reduce the thickness of the material, thereby reducing the material, and the unequal thickness wheel can not be produced by the existing manufacturing method, only
- the corresponding pressing mold can be designed according to the force requirement of the wheel.
- both the production of the rim and the production of the spokes are produced by the method of rolling stamping deformation. In the process of rolling deformation, the rolling master is open, and the material is not binding, and The rolling wheel is controlled to be displaced in the radial direction, which only changes the shape of the workpiece surface without changing the thickness of the workpiece.
- the rolling process is used to further complete the deformation of the rim, thereby further accurately forming the rim portion of the plate wheel directly from the rim initial shape of the integrated plate wheel, thereby completing the key steps of manufacturing the weld-free plate wheel.
- the type of process step is to gradually and slowly cold-roll, cold-extrude and bend-deform within the plastic deformation range of the material to form a high-strength rim section.
- the production process of the integrated sheet non-weld wheel forming method of the present invention is far less than the existing method of manufacturing the plate wheel, and therefore the molding method according to the present invention can greatly improve the production efficiency.
- the integrated plate non-weld wheel forming method of the present invention adopts the rolling forming and rolling type process, the production process of the plate wheel is integrated, without the need for butt welding, thereby greatly improving the rigidity of the wheel. , strength and longevity.
