Abstract

The invention discloses a quenching water heat recovery system for heat treatment of aluminum alloy wheels, which comprises a quenching tank in which a water supply pipe is communicated, and a water delivery pipeline extending to a painting and cleaning reservoir is also arranged in the quenching tank. The water delivery pipeline is provided with a water pump. The hot water in the quenching tank is sent to the painting and cleaning reservoir, which can not only reduce the water temperature in the quenching tank by timely replenishing water, so as to improve the heat treatment effect, but also reduce the energy consumption of heating the cleaning water before painting, killing two birds with one stone .

Description

technical field [0001] The invention relates to the field of wheel hub manufacturing, in particular to a heat treatment quenching water heat recovery system for an aluminum alloy wheel hub. Background technique [0002] The wheel hub is the part of the vehicle used to connect the tire and the shaft. From the manufacturing process, it can be divided into three types: integral casting type, integral forging type and composite type. The integral casting type wheel hub occupies most of the market share due to its low cost. Some integrally cast wheels will undergo heat treatment. A batch of wheel blanks will be heated and then placed in a quenching tank for rapid cooling. After the wheel hub blanks are taken out, the water temperature in the quenching tank will exceed 90 degrees Celsius, and the next batch of wheel hub blanks will be immersed in the quenching tank. At this time, the water is still 70~80 degrees Celsius after natural cooling, and the slightly higher water temperat...
