According to Liu Yawen, an engineer involved in research and development, the intelligent steel sawing and threading grinding line and the seam welding machine are the key research and development products of the company in the first half of the year. The 1.5-meter rolling cage welding was put into production, which greatly compensated the company's rolling cage below 2 meters. The vacancy of welding equipment adds new highlights to the company's intelligent steel processing. WG-12B CNC bending machine is suitable for straightening, bending and shearing HRB335 hot-rolled ribbed steel with diameter φ6-φ12mm, HRB400 hot-rolled ribbed steel bar, light round steel bar and cold-rolled ribbed steel bar. The utility model has the advantages of convenient operation, high production efficiency, and the like, and can bend more than one hundred different shapes of the workpiece, and the workpiece has a regular shape and an accurate size. When bending ribbed steel bars, the transverse ribs and longitudinal ribs have no obvious damage and the mechanical properties are stable. The machine can be widely used in the construction industry, steel processing plants and steel distribution departments.
