| Abstract: | One kind of new dieless drawing methods for making wire-pole is studied, which solves the difficult problems with plasticity forming of wire-pole. The dieless drawing technique is established, the mathematical model of dieless drawing speed for wire-pole is set up, and the methods to ascertain key technique parameter are given out, based on systematically researching and analyzing on deformation mechanism of wire-pole. The process equipment of dieless drawing method is simpler than the traditional processing methods. Since it is not restricted by mold, the method is particularly suitable for variable section pipes with high strength, high friction, low plasticity and long dimension, which are difficult to form by conventional processing methods. |
