Embodiment Construction

[0051] Such as figure 1 Shown is a quenching device for rapid and uniform automatic quenching of aluminum alloy wheels, which includes a reclaimer 1 and a quenching water tank 2 placed under the reclaimer 1 .

[0052] Reclaimer 1

[0053] Such as Figures 1 to 3 As shown, the reclaimer 1 includes a pair of horizontal guide rails 11 arranged in parallel, a dolly 12 that is arranged on the pair of horizontal guide rails 11 and walks horizontally along the guide rail, and a reclaiming lifting assembly 13 that is arranged on the dolly 12; The tail end of 12 is provided with the counterweight 14 of balance center of gravity.

[0054] Dolly 12 comprises vehicle frame 121, is arranged on the driving motor 122 on the vehicle frame 121 side, is installed on the first sprocket wheel 123 on the first driving motor 122 output shafts, is fixed on the car that is arranged on the bottom of the first driving motor 122. The first roller 125 and the second roller 126 that are coaxially arran...

Abstract

The invention discloses a quenching device. A quenching water tank 2 comprises a bottom water spraying pipeline, a side water spraying pipeline and a water return pipeline, wherein the bottom water spraying pipeline is arranged on one side of the bottom of the quenching water tank 2; the side water spraying pipeline is arranged on the inner side wall, far away from the bottom water spraying pipeline, of the quenching water tank 2; a plurality of nozzles are arranged on the bottom water spraying pipeline and the side water spraying pipeline; and a heat exchanger is arranged on the water return pipeline. Through the plurality of nozzles on the bottom water spraying pipeline and the side water spraying pipeline are correspondingly sprayed to the bottom and the side surface of a quenching part, and the quenching part can be cooled uniformly due to the fact that the water temperature of the bottom of the quenching part is consistent with the water temperature of the side surface of the quenching part.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal heat treatment equipment, in particular to a quenching device. Background technique [0002] In order to cope with the energy crisis and protect the environment, the lightweight of passenger cars has become a major trend in the development of the automotive industry. Compared with steel, aluminum alloy has the advantages of light weight, high specific strength, corrosion resistance, and good heat dissipation. The use of aluminum alloy materials for auto parts is one of the most effective ways to reduce the weight of automobiles. [0003] Compared with steel wheels, aluminum alloy wheels can significantly reduce vehicle weight and reduce emissions. In order to improve the strength of the aluminum alloy wheel hub and meet the performance requirements, it must be strengthened by solid solution-quenching-aging heat treatment. Among them, the purpose of quenching is to obtain a supersaturate...
