Ultrahigh-load aluminum alloy wheel extrusion-forming and spinning wheel mechanism

Abstract

The invention discloses an ultrahigh-load aluminum alloy wheel extrusion-forming and spinning wheel mechanism. The ultrahigh-load aluminum alloy wheel extrusion-forming and spinning wheel mechanism comprises a spinning wheel (1), a spinning wheel base (4), a mandrel (7), a locking nut (9), and an upper end cover (10), wherein the mandrel (7) and the upper end cover (10) are fixed by the locking nut (9); the upper end cover (10) is fixedly arranged on the upper end surface of the spinning wheel base (4); and the spinning wheel (1) is fixedly arranged on the mandrel (7) and is sealed by a sealing ring (8). The ultrahigh-load aluminum alloy wheel extrusion-forming and spinning wheel mechanism is characterized in that radial force and axial force, which are borne on the spinning wheel (1), arereleased through a centering bearing I (2), a thrust bearing I (3), a thrust bearing II (5) and a centering bearing II (6) on the spinning wheel (1) through rotation of the mandrel (7). Before the spinning wheel is in contact with a high-speed rotating aluminum alloy wheel, radial force and axial force generated in all extruding and stretching processes are borne in a combined mode through the spinning wheel and a bearing of the spinning wheel, so that rolling precision and service life are guaranteed, and surface smoothness of a spun product is improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a special spinning wheel mechanism for extrusion and stretching forming machines of aluminum alloy wheels. Background technique [0002] At present, most of the aluminum alloy wheels on the market are cast wheels. Due to the limitation of the process, in order to ensure safety, the cast wheels can only be designed with thicker wall thickness to ensure the mechanical strength and achieve the purpose of safety and reliability. The thicker the product, the heavier the weight of the product, resulting in higher fuel consumption of the car. At present, the spokes are gradually cast out in the market, and then the rim part is extruded and stretched, or the wheel blank is forged, and the rim is extruded and stretched. Aluminum alloy wheels are produced by advanced technology to achieve the effect of weight reduction under the premise of ensuring safety. The spinning whe...
