According to the materials, loading and manufacturing technology of the parts, the cabinet can be divided into profiles and sheet two basic structures.
1. Profile structure cabinet: steel cabinet and aluminum cabinet. Aluminum cabinet made of aluminum alloy profile has certain stiffness and strength, suitable for general equipment or light equipment. The cabinet has the advantages of light weight, small processing capacity, beautiful appearance and so on, and has been widely used. The steel material cabinet is made of profiled seamless steel tube with good rigidity and strength, suitable for heavy equipment.
2. Thin plate structure cabinet: the side plate of the whole cabinet is bent by the whole steel plate, suitable for heavy duty or general equipment. The structure of the curved plate and column cabinet is similar to that of the special-shaped material cabinet, and the column is formed by bending the steel plate. This cabinet has a certain stiffness and strength, the structure of the curved plate and column cabinet is similar to the special-shaped material cabinet, the column is formed by bending steel plate. This cabinet has certain rigidity and strength, suitable for general equipment. However, because the side plate is not detachable, it is not easy to assemble and maintain.
