The edge of steel plate is difficult to be bended during the process of J-ing, C-ing and O-ing by the way of winding through a core roller and may remain the shape of linear form which is harmful to the quality of welded pipe. A new type of clamp possess mobile function along radial direction, has been provided to improve the edge bending effect of steel plate and numerical experimentation has been employed to foreshow the effect of this new type of clamp. Further experimentation in real situation shows that the improved clamp is feasible and effective in real production.
