Definitions
- the present invention relates to a method for manufacturing a full face wheel for an automobile, and more particularly to a method for manufacturing a full face wheel rim for a steel automobile.
- a full-face wheel for automobiles has a joint opening formed at one open end of a full-face wheel rim on the back of a wheel disk that has a flange portion formed on the outer periphery to hold the tire bead from the side.
- Manufactured by welding In general, the peripheral edge of the joint opening of the full face wheel rim is welded from the outside in the circumferential direction in a state where the peripheral edge of the joint opening is abutted to a predetermined position which is substantially flat on the rear surface of the wheel disc. is there.
- Patent Document 1 having a joint opening end with a chamfered outer peripheral end
- the structure is generally intended for an aluminum full-face wheel formed by molding.
- the desired edge of the joining opening is formed by chamfering.
- the fabrication die is relatively expensive, so that after the usual fabrication is performed, a new cutting process is provided to form the mold.
- this cutting process complicates the manufacturing process and increases the manufacturing cost.
- a finole face wheel rim may be formed with a flange at each of the openings in the case where the outer peripheral surface is chamfered as described above to form the peripheral end of the joint opening.
- This manufacturing method has the advantage that it can be formed in the same manner as other drop-fitting type wheel rims or bead-fitting type wheel rims, and has the convenience of transportation during the manufacturing process.
- this manufacturing method has problems such as the necessity of the cutting step as described above, and the wasteful use of an amount of raw material corresponding to the flange to be cut.
- Patent Document 2 in which the peripheral end of the joint opening is bent inward (Patent Document 2), it is possible to form without the need for a cutting process as in the above configuration. is there.
- the bent peripheral portion at the peripheral end of the joint opening is extended inward, a relatively wide area is formed in the bent peripheral portion from the inner peripheral end to the outside when welding from the outside. It will be. For this reason, a stress is repeatedly applied to the inner peripheral edge of the bent peripheral portion from a load applied to the wheel during traveling, and deformation may be caused by the stress.
- a relatively large area of the wheel disc where the entire bent peripheral portion is joined has high rigidity, stress concentration is likely to occur at the joint boundary of the bent peripheral portion. Therefore, in such a configuration, there is a problem that destruction easily occurs near the inner peripheral end of the bent peripheral portion where the wheel rim and the wheel disk are joined.
- An object of the present invention is to propose a method for manufacturing a steel full-face wheel rim for a vehicle, which can relatively easily cause sufficient penetration by welding and exhibit excellent durability. Disclosure of the invention
