The tubing is clamped on the bending wheel die. With the bending die together, the pipe is squeezed on the wheel die when the pipe is pulled over the pressure block, which belongs to the forming die bending process. With the development of numerical control bender and CNC machine tool industry, the use of advanced CNC pipe bending machine can greatly improve the production efficiency and guarantee the quality of the product. Because the process can be conveniently adjusted, the NC can complete the straightening, straightening, feeding and bending processes accurately and stably. The bending accuracy of the tube parts is guaranteed. However, the quality of the curved copper tube is more sensitive to the process parameters, it is necessary to have sufficient prep-reparation and trial production, especially the curved thin-walled copper tubes. If the selection of the process is not appropriate, it is easy to wrinkle and cause the work piece to be scrapped. How to obtain these qualities and accurately, and fully guarantee the quality of elbow products. It is the pilot of the research on the technology of the NC pipe bending machine.
