One end of rolling wheel is a helicoid.
Compared with the prior art, the utlity model has following advantage:
1. can carry out cold stretch and roll extrusion to workpiece simultaneously, and chipless produces.Even reach material more than the HRC40 for hardness, also can realize workpiece spindle to radially distortion, solved high strength, particularly the directly simple roll forming of the high hardness alloy material problem of difficulty relatively;
2. the consumption of material, the energy can be reduced significantly, environmental pollution can also be alleviated;
3. workpiece surface quality is good, obviously is better than the surface quality of machining, helps improving part fatigue life.
