Technical Field

[0001] The utility model relates to the technical field of metal cutting, in particular to a low-loss copper rod sawing device. Background Art

[0002] Copper has good electrical conductivity, thermal conductivity, ductility and other advantages. It is the most widely used non-ferrous metal. It is used in electrical appliances, ships, electrical equipment, vehicles, machinery manufacturing, etc. When people use copper, they need to process it into materials of different shapes. Among the copper processed products, there are plates, strips, tubes, rods, wires, profiles and forgings. The performance of copper processing equipment is crucial to the production of copper products. The copper rod cutting device is a common copper rod processing equipment.

[0003] When the existing copper rod cutting device is in use, in order to ensure the cutting effect, the two ends of the copper rod are generally fixed, but this will cause the middle part to be suspended for a long length, so that when the copper rod is sawed, the copper rod will still vibrate to a certain extent, resulting in an uneven cutting position, that is, the sawing loss of the copper rod is large, and the process of fixing the copper rod with the existing cutting device is also cumbersome, and usually requires manual operation by the staff, which affects the work efficiency. Utility Model Content
