CNC rolling and bending machine is a CNC forming and bending equipment. Bending processing is the use of a CNC roll bending machine to shape thick walled metal into cylindrical parts, including refractory metals, non-ferrous metals, stainless steel, and other materials. Through a powerful CNC roll bending machine, it is spun into thin-walled pipes or formed into hollow rotary machining. Bending processing is the process of clamping the blank onto the core, and the CNC rolling bending machine drives the core and blank to rotate at high speed together. At the same time, local deformation of the blank is achieved through rolling and feed motion, resulting in an axisymmetric part.

The bending mold is simple and locally deformed. Larger parts can be processed with less power and tonnage, and used for small batch production. And complex parts. The principle of CNC rolling and bending machine is that when the workpiece rotates at high speed, a large external force presses the workpiece along the path. The drum repeatedly presses the material from one point to another. From line to surface, the workpiece undergoes thermal deformation to form the desired shape. Different extrusion pressures are required. Small CNC bending machines driven by servo motors produce pressure screws, while some large and powerful CNC bending machines require hydraulic extrusion.

The basic principle of metal spinning technology is similar to that of ancient ceramic production technology. Rotating molded parts are usually cylindrical or disc-shaped parts of a rotating body, usually thick walled cylindrical parts or circular pieces. The principle and structure of CNC rolling and bending machines are similar to those of metal cutting lathes.

At the position of the lathe, it is designed to have a rotating wheel frame with axial movement force. The wheel fixed on the wheel frame can move radially; The coaxial connection with the spindle is the spindle (shaft). Spinning the blank onto the spindle (shaft); Due to the frictional force generated by contact with the billet placed on the spindle (shaft), the roller rotates in the opposite direction; Meanwhile, the roller carrier is located inside the axial high thrust cylinder.

The influence of axial motion on CNC rolling and bending machines. Under the combined action of axial and radial forces of the rotating wheel, the rotating wheel frame undergoes continuous plastic deformation point by point on the surface of the billet. The CNC bending machine manufacturer reminds you that the top support position of the lathe is designed with a tail end hydraulic cylinder that is the same as the spindle axis. The hydraulic cylinder applies axial thrust to the blank end face placed on the core mold (shaft).
