Aluminum-magnesium alloy die casting surface treatment device and treatment method

Abstract

The invention belongs to the technical field of aluminum-magnesium alloy treatment, and particularly relates to an aluminum-magnesium alloy die casting surface treatment device and a treatment method.The device comprises a controller, a motor, a belt pulley, a base, an air cylinder, an air bag, a box body, an end cover, a clamping unit and grinding balls; the belt pulley is positioned behind thebase; the box body is positioned above the base; the end cover is arranged above the box body; the motor is fixedly arranged at the top of the end cover; the clamping unit is positioned inside the boxbody; and the grinding balls are uniformly distributed at the bottom of the inner side of the box body. The box body is driven by an eccentric belt pulley to intermittently swing forwards and backwards, so that the swinging of the box body is increased; an electric push rod is arranged to push a clamping table, so that the clamping and fixing of the clamping unit are more firm, a plurality of layers of aluminum-magnesium alloy die castings are able to be superposed, the clamping quantity is increased, and the grinding efficiency is further improved; and the flexible grinding balls with through holes are arranged, so that a surface to be treated is not damaged when the grinding balls directly knock the surface of the casting on the premise of no influence to the grinding efficiency.

Description

technical field [0001] The invention belongs to the technical field of aluminum-magnesium alloy treatment, in particular to a surface treatment device and treatment method for aluminum-magnesium alloy die-casting parts. Background technique [0002] The main element of aluminum-magnesium alloy is aluminum, and a small amount of magnesium or other metal materials are added to strengthen its hardness. The aluminum alloy with Mg as the main additive element is also called anti-rust aluminum alloy because of its good corrosion resistance. Because it is a metal itself, its thermal conductivity and strength are particularly outstanding. After the aluminum-magnesium alloy die-casting is processed, the surface will have burrs, so the surface needs to be treated. At present, it is generally manually polished, which is labor-intensive and low-efficiency. [0003] There are also some technical solutions for surface treatment devices for aluminum-magnesium alloy die-castings in the pri...

AI Technical Summary

Problems solved by technology

[0004] Although this kind of technical scheme is used, there are technical schemes with reasonable structural design, which can replace manual grinding. Through the cooperation of circular quartz beads and vibration motors, the surface of aluminum-magnesium alloy die-casting parts can be ground, improving the grinding efficiency, and has strong practicability, etc. Advantages; however, this type of preparation method cannot effectively ensure that the clamping device can clamp and fix the aluminum-magnesium alloy die-casting when the box vibrates, and it cannot be set to clamp multi-layer aluminum-magnesium alloy die-castings at the same time, and the vibration amplitude of the box is relatively large. Small, the grinding efficiency needs to be improved; and during the grinding process, the quartz beads will inevitably hit the surface to be treated, and then leave pits on the surface of the die casting, resulting in the surface quality of the ground aluminum-magnesium alloy die casting not up to standard; for Therefore, we propose a surface treatment device and treatment method for aluminum-magnesium alloy die castings to solve the above problems
