Description

technical field [0001] The invention relates to the technical field of manufacturing auxiliary equipment for mechanical processing, in particular to a polishing machine. Background technique [0002] The polishing of metal materials is to use the polishing wheel driven by the polishing equipment to modify the surface of the workpiece to remove the oxide layer on the metal surface, so as to achieve the purpose of beauty or convenience for subsequent processing. At present, there are many polishing tools on the market, roughly including manual type, hand-push type, and automatic type. Manual type and hand-push type polishing equipment have simple structure and low price, but the polishing speed is slow and the polishing effect is poor. Labor intensity is high; the structure of automatic polishing equipment is relatively complex, and the polishing effect is good, but due to its structural reasons, it can only make the polishing wheel rotate itself and the entire polishing wheel...

Problems solved by technology

At present, there are many polishing tools on the market, roughly including manual type, hand-push type, and automatic type. Manual type and hand-push type polishing equipment have simple structure and low price, but the polishing speed is slow and the polishing effect is poor. Labor intensity is high; the structure of automatic polishing equipment is relatively complex, and the polishing effect is good, but due to its structural reasons, it can only make the polishing wheel rotate itself and the entire polishing wheel move up and down, and when the polishing wheel moves , the polishing external force can only be applied by its own gravity. In this way, the flatness of the polished metal sheet is high, and the adaptability to the oxide layer with different densities on the surface of the material is poor, so it is usually only used for polishing. Polishing of stainless steel or steel plates without a dense oxide layer on the surface

[0003] In the production of metal explosive composite panels, for composite panels, due to the poor flatness and the thicker and denser surface oxide layer after heat treatment, the existing automatic polishing machine cannot meet the polishing requirements; for carbon steel panels, due to the storage time Different from the production process of the steel mill, the situation of the oxide layer on the surface of the steel plate is also different.

Some steel plates have a thin oxide layer, which can be removed by traditional manual polishing; while some steel plates have a firm oxide layer on the surface, which is very dense and smooth, and it is difficult to polish it off even by chemical and mechanical methods, often requiring back and forth Repeated polishing several times, both manpower and material resources, production efficiency is very low

[0004] At the same time, the existing polishing equipment, no matter manual or automatic, lacks dust-proof and dust-removing devices, the metal dust is very large during polishing, and the working environment is extremely poor
