Press brake is suitable for large steel structure parts, iron towers, street lamp poles, high lamp poles, automobile beams, automobile trucks and other related industries. The essence of CNC bending machine is a CNC press brake die for sheet metal. The die consists of bracket, worktable and clamping plate. By electrifying the coil, the force of gravity on the sheet metal is generated, thus the clamping of the sheet metal between the sheet metal and the base metal is completed. Because the electromagnetic force clamping method is adopted, the pressing plate is made according to the specific workpiece requirements. The operation is simple, and the workpiece with side wall can be processed. CNC bending machine has different models, common G, F, WC67K and so on. The plastic sheet numerical control bending machine is developed on the basis of the principle that the plastic sheet is heated and softened by melting and welding. It is suitable for the bending angle of all thermoplastic materials. The mould of the numerical control plastic sheet bending machine has the following characteristics: Direct bending, no splicing, no grooving, no welding rod. Its bending angle appearance is beautiful and water leakage is not needed. At the same time, the processing speed is fast, the bending angle treatment surface is beautiful and the strength is high. It transforms manual welding into automatic machine operation, improves quality, improves labor efficiency, reduces labor costs, and greatly shortens the production cycle of products.
