Characteristic

1.Multi-Stage CNC Roll Forming Full CNC controlled machine can complete multiple position roll forming with different parameters on the same workpiece, so it can be called as king of roll forming. 2.CNC Motor Drive With Low Energy Consumption Compared with hydraulic drive, CNC-drive saves 70% energy, which meets the needs of the times. So it is low consumption high efficient equipment in the true sense. 3.High Performance With Less Procedures Multi-stage processing technology reduces labor intensity, making it possible for a person to operate multiple devices; and it also reduces product flow, uses less procedures and reduces product clashes. 4.Vertical Structure The main sliding table travels in vertical symmetry movement, which is conducive to chip removal and workpiece cooling, significantly reducing guide rail wearing; and, the compact vertical structure with CNC-drive greatly reduces ground area occupation. 5.Overall Frame Structure Hexahedral frame support connection greatly enhances the overall rigidity of the machine body, which increases the stability of the machine. 6.User-Friendly Operation Interface The system can display fault information, processing count, timing, storage program, detection of the total length of the workpiece, anti- faulty or empty clamping, self-learning and so on.

Processing principles

The principles of cold-roll forming are that the roll forming cutter dies installed on the sliding table operate in opposite linear motion. The workpiece splines are formed by the increasing teeth amount of the roll forming cutters, and the final shaping precision and stability of the splines are obtained by the rigid distance between the two roll forming cutters. The opposite linear movements of the roll forming cutters are driven by hydraulic machine and the high synchronization of the two roll forming cutters is guaranteed by the racks and pinions. The synchronization of two roll forming cutters is guaranteed by the ball screws on the CNC machine. (Its synchronization accuracy is higher)
