Method for efficiently reducing bubbles on surface of aluminum bar and using device thereof

Abstract

The invention discloses a method for efficiently reducing bubbles on the surface of an aluminum bar and a using device thereof. The using device comprises a base, a supporting column, a concave cavity and a hydraulic rod, wherein the supporting column is fixed on one side of the upper end of the base, the concave cavity is formed in the upper end of the supporting column, the hydraulic rod is fixed in the concave cavity, a fixing frame is installed at the top end of the hydraulic rod, a material guide hopper is arranged on the fixing frame, a material guide pipe is arranged at the bottom end of the material guide hopper, and a magnetic plate is installed in the material guide hopper. The method and the using device have the beneficial effects that an electric push rod, a scraping plate and a connecting rod are arranged, in the bubble eliminating process, the electric push rod enables the scraping plate to move up and down in a mold cavity through the connecting rod, then the bubbles gathered on the inner wall of the mold cavity are eliminated, meanwhile, a vibration machine is matched, so that the number of the bubbles on the surface of the aluminum bar during forming can be effectively reduced, the percent of pass of the aluminum bar is improved, and the practicability and the working effect of the device are improved.

Description

Technical field [0001] The present invention relates to a technical field of production apparatus rod, in particular, it relates to an efficient method of reducing the surface of the bubble and the aluminum bar using a device. Background technique [0002] Aluminum rods are one of aluminum products, and the molten casting of aluminum rod includes melting, purification, bughing, degassing, slag, and casting process. Depending on the metal element contained in the aluminum bar, aluminum bars can be divided into eight categories, the need for the manufacturing process to eliminate its rod surface of the bubble. [0003] Conventional aluminum rod surface of the bubble in the course of the method is a bubble in the liquid aluminum is eliminated by way of vibration, but during vibration Some bubbles will collect on the inner wall of the mold cavity, resulting that it can not be eliminated, and thus will exist a large number of pores at the surface of molded aluminum rod, passing rate i...

Problems solved by technology

[0003] The existing method of air bubbles on the surface of aluminum rods is to eliminate the air bubbles in the molten aluminum through vibration during use, but some air bubbles will gather on the inner wall of the mold cavity during the vibration process, making it impossible to remove them. Elimination, and then there will be a large number of pores on the surface when the aluminum rod is formed, which will affect the pass rate of the aluminum rod, reduce the practicability and working effect of the device, and secondly, the existing method of air bubbles on the surface of the aluminum rod is through cold air during use This method cools and molds the molten aluminum, but because this method cannot cool the molten aluminum as a whole, the cooling rate of each position of the molten aluminum is inconsistent, which in turn affects the forming effect of the aluminum rod and reduces the functionality of the device. In addition, the existing aluminum rod In the method of material surface bubbles, during the injection process, the source of the aluminum liquid is melted and refined by different substances, and there are some iron filings and other impurities in the aluminum liquid, which cannot be filtered and removed, and then The presence of these impurities in the aluminum rods affects the purity of the aluminum rods. Therefore, there is an urgent need for an efficient method for reducing air bubbles on the surface of aluminum rods and its use to solve the existing problems.
