Aluminum alloy pressure casting workpiece multi-medium air cooling device

Abstract

The invention relates to an aluminum alloy pressure casting workpiece multi-medium air cooling device. An axial flow fan is fixed to a fan supporting plate. The two sides of the fan supporting plate are connected to a multi-station adjustable working panel through a bolt. The multi-station adjustable working panel is fixed to the fan supporting frame through a bolt. The fan supporting plate adjusts the height and the angle of the axial flow fan by changing the connecting position of the bolt and the multi-station adjustable working panel. The upper portion of the axial flow fan communicates with an air pipe of an air cooler, or a nozzle atomizing device is additionally arranged between the axial flow fan and a pressure casting workpiece, and switching of multiple media is achieved. A workpiece table is arranged in the fan supporting frame and located under the axial flow fan. The pressure casting workpiece is fixed to the workpiece table through a locating clamp. The workpiece table isconnected with temperature measuring devices through thermocouple fixing devices. The multiple temperature measuring devices are arranged on the portion, difficult to cool, of the bottom of the pressure casting workpiece, the temperature measuring devices are connected with a thermodetector, the thermodetector transmits measured data to the computer end, and the temperature change situation of the workpiece can be monitored in real time.

Description

technical field [0001] The invention relates to a cooling device in an aluminum alloy die casting production line, in particular to an air cooling device. Background technique [0002] The development of the die-casting industry is closely related to the automobile industry. In recent years, with the rapid development of my country's automobile industry, the die-casting industry has also developed rapidly. Under the premise that people tend to demand high performance, low pollution, and low energy consumption for automobiles, the weight of automobiles plays a decisive role in fuel economy. Using lightweight materials to manufacture auto parts is an effective way to reduce the weight of automobiles. Due to its excellent material properties, convenient forming and light weight, aluminum alloy die castings are widely used in the automotive industry. [0003] In the automatic die-casting production line, aluminum castings need to be cooled before subsequent processing can be pe...

Problems solved by technology

In the prior art, there are three cooling methods: the first is the natural cooling method, which transports the die-casting parts to a fixed position and allows them to cool naturally. Although this cooling method is simple, it is greatly affected by the working environment and the cooling is slow. , low efficiency; the second method often uses water cooling or oil cooling to cool the workpiece. Although this cooling scheme can quickly cool the workpiece, it will cause uneven cooling, affecting the quality of some workpieces and subsequent processing. For thin Due to severe cooling of the wall parts, the workpiece will be deformed, and for some workpieces with deep holes, there will be residual water in the hole, and the reject rate will increase a lot; the third is the forced air cooling method, generally using several The fans arranged side by side cool the workpieces on the conveyor belt. The fans rotate at a fixed height, angle and air volume, which cannot be adjusted according to the shape and cooling requirements of different workpieces in the production line. The cooling medium is limited to normal temperature air, which limits the cooling efficiency. promotion
