A process for manufacturing an aluminum alloy wheel includes: casting, de-flashing, soaking, spinning, thermal treatment, de-gating, X-ray and machining. During the casting, a casting mold is cooled with water, and a cast blank is produced from carrying out the casting. The de-flashing includes removing flashes of the cast blank at a rim of the cast blank with a de-flashing device. The soaking includes reheating on the cast blank that has been de-flashed. The spinning includes an adaptive spinning mold. The thermal treatment includes direct solution treatment and aging on the cast blank in a thermal treatment furnace after spinning.

A full-electric servo vertical three-counter driving power spinning device includes a rack, and the rack includes a baseplate. A workpiece active rotating mechanism and an inner roller feeding mechanism are provided on the baseplate, an outer roller feeding mechanism is provided on the rack; the outer roller feeding mechanism is provided with an outer roller active rotating mechanism; the outer roller active rotating mechanism includes an outer roller active rotating motor and an outer roller, and the inner roller feeding mechanism includes an inner roller. A stress state of a cylinder material by adopting a combined method of an active rotation of a roller and an active rotation of a workpiece turntable is significantly different from that by a passive spinning of a counter-roller, thus improving a thinning rate of a wall thickness of a cylindrical member and a hardening properties of materials.

In a spinning forming method, a plate including a peripheral portion at which a ring-shaped projection is provided is used, the projection projecting in a thickness direction of the plate. Further, while rotating the plate, a transform target portion of the plate is locally heated, and a processing tool is pressed against the transform target portion to transform the plate. According to this configuration, a heat capacity of the peripheral portion of the plate can be increased. With this, when heating the vicinity of the peripheral portion of the plate, the peripheral portion can be prevented from becoming high in temperature. As a result, deformation of the peripheral portion of the plate can be suppressed.

A machine for spin-forming a solid disk blank having a center axial bore into a pulley configuration exhibiting an outer peripheral pulley groove and a flanged bore bearing retainer. Die members maintain the disk blank on the machine axes by clamping the disk blank between an upper and lower die members. A power source affects rotational motion of at least one of the die members to affect rotation of the disk blank. A splitting tool, a swaging tool, and a splitting-swaging tool are moveable for engaging the disk blank and affecting splitting and swaging of the bore and peripheral edge. A rotatable inner tool spindle comprises the splitting-swaging tool connected thereto and is movable horizontally such that the tool splits and swages the center axial bore. A power source affects rotational motion of the spindle and thus the rotational motion of the splitting-swaging tool.

A spinning forming method includes: preparing a plate including a back surface at which a ring-shaped projection is formed along an outer peripheral edge of the plate, a ratio of a thickness at a reference position of the plate to a thickness at a tip end of the projection being 0.7 or less, the reference position being a position where an inclination of a portion of the back surface which portion extends toward the tip end of the projection is 45 or more; rotating the plate; moving a processing tool outward in a radial direction from an inner side of the projection to a position above the projection while pressing the processing tool against a front surface of the plate that is rotating; and locally heating a portion of the plate against which portion the processing tool is pressed.

The present disclosure discloses a method for forming a rim of a cast-spun aluminum alloy hub, that is, a special spinning composite machining method for forming a structure that the spokes and the inner wheel flange of the hub are cast and the middle of the rim is spun. The method can prevent the performance, strength and as-cast structure of the inner wheel flange from being destroyed, effectively improve the impact resistance of the cast-spun hub at the inner wheel flange, prevent the inner wheel flange of the cast-spun hub from cracking during radial impact and improve the performance of the spun structure of the rim, is beneficial to thinning the rim and realizes light weight of the rim.
