Description

Technical Field

[0001] The invention relates to the technical field of metal bar profile processing, and in particular to a bending device used for metal bar profile processing. Background Art

[0002] A metal rod is a rod made of metal. Metal is a substance with luster (i.e., strong reflection of visible light), ductility, easy conductivity and thermal conductivity. The above properties of metal are related to the free electrons contained in metal crystals. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Most metal minerals are oxides and sulfides, and other forms include chlorides, sulfates, carbonates, and silicates. The connection between metals is a metallic bond, so the connection can be re-established by changing the position at will, which is also the reason why metals have good ductility. Metal rods are a common metal processing raw material and are widely used in mechanical processing. During the processing, the metal rods often need to be bent by a bending device; When bending metal bars, it is impossible to bend at the specified position according to the requirements, and the metal bars are prone to slipping during cutting and bending, resulting in bending dislocation. In addition, strong bending will cause severe vibrations, resulting in uneven surface depressions at the bending points of the metal bars. At the same time, the dust particles covering the surface of the metal bars are embedded in the surface during bending and are difficult to remove. Therefore, we proposed a bending equipment for metal bar profile processing. Summary of the invention
