Abstract：

A new dieless drawing method for making tapered pipe was introduced,which solved the plasticity forming problem of tapered pipe.A dieless drawing technique for tapered pipe was developed and the mathematical model of dieless drawing speed was determined based on the systematically researching and analyzing on deformation mechanism.The experimental study shows that the dieless drawing technique is reasonable and novel,and the equipment is simple.The established mathematical model of dieless drawing speed expresses the law of dieless drawing speed and hot-cooling source speed quite well and it has the practical value.
