Disclosed in the present disclosure is a process for manufacturing an aluminum alloy wheel. The process flow comprises: casting, de-flashing, soaking, spinning, thermal treatment, de-gating, X-ray and machining. The process reduces the cost by about 18 yuan/piece and reduces the weight of the finished product by 0.7-1.1 Kg by improving the casting production efficiency and the product quality, saving original cooling compressed air, canceling pre-machining, preheating and spinning the thermal blank, thermally treating the thermal blank and the like, has the cost equivalent to the comprehensive manufacturing cost of an ordinary cast wheel, and improves the market competitiveness of the cast-spun wheel. The process realizes short flow, light weight and low cost for manufacturing a cast-spun wheel, achieves intelligence of machining, and is suitable for automatic production of large-batch cast-spun wheels.

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.

A spinning method includes supporting a supported portion of a cylindrical work by a work supporting portion; pressing a first roller of a spinning head against a processed portion of the work while revolving the first roller; and performing a forming process that points a tube axis of the processed portion of the work in a given direction by pressing the first roller and a second roller in which a plane of revolution thereof is provided in a different position, in a rotational axis direction of a spindle of the spinning head, than a plane of revolution of the first roller, while revolving the first roller and the second roller, and moving the work supporting portion relative to the spinning head or moving the spinning head relative to the work supporting portion, while the first roller and the second roller work in cooperation with each other to retain the work.

A method for producing a formed body includes providing a round or pre-formed semi-finished product of a steel material, and heating the semi-finished product at least in regions to a first temperature. The method further includes forming a hub on the semi-finished product warm at least in regions, for generating a preform having an upper geometric element. The method further includes heating or re-heating the preform having an upper geometric element at least in regions to a second temperature, and forming a bell on the preform having an upper geometric element warm at least in regions, for generating a preform having an upper and at least one lower geometric element. The method further includes heating or re-heating the preform at least in regions to a third temperature, and profiling the preform warm at least in regions for generating a formed body in a third operative step.

A rotary flow forming apparatus for producing light alloy rims contains a main spindle with a clamping apparatus for a rim blank. An outer pressure roller is provided and is deliverable radially from the outside in and is movable parallel to the spindle axis, for producing an outer contour of the light alloy rim. The apparatus does not require massive internal dies and thereby significantly reduces the production costs and significantly improves the efficiency of rim production, which is achieved by the fact that the rotary flow forming apparatus has an inner pressure roller for generating an inner contour of the light alloy rim, which is arranged in the region of the inner side of the rim blank opposite the outer pressure roller and is mounted so as to be movable parallel to the spindle axis, rotatable, and deliverable radially from the inside outward to the rim blank.

A spinning forming device includes: a rotating shaft that rotates a plate to be formed; a processing tool that presses a front surface of the plate while being moved outward in a radial direction of the rotating shaft; and a heater that is moved so as to be located on the same circumference as the processing tool and locally heats the plate by induction heating. The spinning forming device further includes a cooling device that cools the front surface of the plate.

According to a spinning forming device, while a plate is rotated by a rotating shaft, a transform target portion of the plate is pressed by a processing tool and locally heated by a heater that performs induction heating. The heater includes a coil portion having a doubled circular-arc shape and is inclined by an inclining device relative to a direction from the rotating shaft toward the processing tool. A measuring unit measures distances each from the coil portion to an outer peripheral original portion of the plate at a plurality of measurement points distributed in a circumferential direction of the rotating shaft. A controller controls the inclining device based on a measurement result of the measuring unit such that an angle difference between the coil portion and the outer peripheral original portion becomes not more than a predetermined angle.
