XINYUE spline cold rolling machine CZ-16MY 24MY 36MY 48MY

Specification

Characteristic

1. Increase Tool Mounting Space
16 “/ 24″ / 36 “/ 48″ roll forming tools can be mounted on the machine to complete roll forming processes of multi position splines with different parameters.
2. Optimized Hydraulic Transmission
Customized special hydraulic drive unit consists of imported hydraulic components. Upgraded hydraulic system has a clearer oil piping layout, more properly designed back pressure and buffering and the cylinder propulsion is improved so that the main slider travels very smoothly. And at the same time the noise is greatly reduced.
3. Perfect Synchronization Mechanism
Original Swiss high-precision racks and pinions ensure synchronization of the displacement of the upper and lower cutting tools, which makes the machines runs stabler with optimized hydraulic power.
4. Optimized Hydraulic Power
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.
5. Horizontal Pre-Pull Structure
The optimized internal stiffener arrangement and six-sided frame, and domestic patented combination sliding stud connection greatly enhance the overall rigidity, stability, reliability, security, which guarantees a longer service life 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.

Parts Machined By Roll Forming Machine

Roll forming machine roll forming process

Multi-stage roll forming process

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).
