Abstract
PURPOSE: To stabilize the accuracy of products and enhance productivity by working the leading end of a pipe material to deform the same in the state of long length by means of a tool for expanding the inside diameter of a pipe and a receiving means without cutting the pipe material.
CONSTITUTION: A pipe material (a) is delivered up to the upper prescribed position of the receiving means 15 of a supporting tool B for the outside diameter of pipe and the means 15 is lightly touched to the outside circumferential surface of the material (a). The jig 5 of a tool A for expanding pipe is inserted into the material (a), and is stopped in a prescribed position. Thence, a cross rear D is advanced in an arrow direction to press the side face of a bottomed cylindrical body 7 by means of a pressing rod E, and the material (a) is sandwiched between the jig 5 and the means 15. The material (a) is projected to the outside circumference by the rotation of the jig 5 and the rotation of a collect chuck F, whereby a large diameter part (b) is formed. Thence, the cross rear D is returned to the home position, and the tool A and the cross front C are retreated. Next, the material (a) is subjected to beveling and chamfering of the inside and outside diameters, after which it is cut to a product size.
