Abstract

The invention discloses a method for preparing an aluminum alloy plate for a car body by using an aluminum alloy plate preparation device, which includes a machine body, a melting furnace cavity with an opening facing upwards is arranged in the body, a filter plate is fixed in the melting furnace cavity, and a filter plate is fixed in the melting furnace cavity. The lower side of the furnace cavity is connected with a flow regulating tank, and the right side of the flow regulating tank is provided with a telescopic device, which is used to adjust the flow rate in the flow regulating tank, and the lower side of the flow regulating tank is provided with a molding cavity, the present invention is simple in structure and easy to operate, through the furnace cavity with filter screen, the surface impurities in the molten aluminum alloy can be extracted in the process of forming the aluminum ingot, the forming of the aluminum ingot has continuity, and its forming efficiency is high , and there is less material waste. During the aluminum ingot forming process, the device is equipped with a telescopic device and an adjusting device to adjust the thickness of the aluminum ingot, which is convenient for the later aluminum ingot thinning and coiling operation. This device has low energy consumption, and the process Continuous, easy to operate and use.

Description

technical field [0001] The invention relates to the technical field of aluminum material manufacturing, in particular to a method for preparing an aluminum alloy plate for a vehicle body using an aluminum alloy plate preparation device. Background technique [0002] The forming process of the aluminum alloy plate used for the body is: melting, impurity removal, forming (aluminum ingot), thinning, and body pressing. Among them, the forming process of the aluminum ingot is particularly important. In the current aluminum ingot forming process, the molten For liquid aluminum, the surface impurities need to be removed manually by scraping with auxiliary tools. In this way, the aluminum is easily scraped out of the furnace, resulting in waste of liquid aluminum materials. [0003] The molten aluminum alloy material is poured into the mold, and after rapid cooling, an aluminum ingot is formed. The size and thickness of the aluminum ingot are determined by the size of the mold, and ...

[0002] The forming process of the aluminum alloy plate used for the body is: melting, impurity removal, forming (aluminum ingot), thinning, and body pressing. Among them, the forming process of the aluminum ingot is particularly important. In the current aluminum ingot forming process, the molten Liquid aluminum, in which surface impurities need to be removed manually through auxiliary tools by scraping out the surface impurities. In this way, the aluminum is easily scraped out of the furnace, resulting in waste of liquid aluminum materials

[0003] The molten aluminum alloy material is poured into the mold, and after rapid cooling, an aluminum ingot is formed. The size and thickness of the aluminum ingot are determined by the size of the mold, and the formed aluminum ingot is repeatedly pressed back and forth through the hot roller during the thinning process. Pressing rollers, the time required for this process increases according to the thickness of the aluminum ingot, and the length of the aluminum ingot is getting longer and longer after being thinned, so that the production line is limited by the geographical space, and the thickness of the aluminum ingot cannot be adjusted flexibly. The process of ingot forming is independent, and the devices of each process are independent, which increases the energy consumption of the device, and the manufacturing efficiency of aluminum alloy plate is low
