Description

Technical Field

[0001] This utility model relates to the field of casting production and processing technology, specifically to a sandblasting device for castings in mining machinery. Background Technology

[0002] The production process of castings for mining machinery typically includes steps such as raw material smelting, mold preparation, casting, and cooling / demolding. In the smelting stage, the metal raw material is heated to a molten state, impurities are removed, and then poured into a pre-made mold. The mold is preheated to a high temperature to prevent defects caused by rapid cooling of the molten metal. During casting, pressure or gravity is used to fill the cavity with molten metal. After the molten metal cools and solidifies, the mold is removed to obtain a rough blank. Subsequently, sandblasting is required to remove surface oxide scale, burrs, and adhering sand, improving surface roughness to meet subsequent processing or coating requirements. However, existing sandblasting equipment often lacks adequate protective measures during operation. Operators are frequently directly exposed to the sandblasting environment, where high-speed abrasive particles can easily splash onto their arms and face, causing cuts, impact injuries, and other safety accidents. At the same time, the sandblasting process generates a large amount of metal dust and abrasive debris. Without effective collection and filtration, operators are highly susceptible to inhaling dust particles, which can harm their health. Utility Model Content
