Abstract
PURPOSE: To obtain captioned device which is capable of expanding operation of a diameter a pipe smoothly by a method wherein a multitude of split pieces are journaled so that they may be extended and contracted in a male die, these journaled portions are interlocked with a main spindle which penetrates the male die and each of the split pieces is rotated simultaneously with the rotation of the main spindle so as to expand the diameter of the pipe.
CONSTITUTION: One end portion of a synthetic resin pipe A is heated, softened and held against a tapered surface 22 of a male die 2 so that a socket with an expanded diameter is formed by forcing the end into the male die until the end is abutted against a stopper 23. Then, the bemale die I is fitted and fixed on an external circumference of the socket and then a main spindle b is turned by a specified angle. The displacement by the rotation of this main spindle 6 is transferred to aplit pieces 3 through gears 7, pinions 5. Since each of the split pieces 3 is rotated around a pin 4 as a center thereof, the sircular arcs of the formed parts 31 are expanded and a swelled groove for a rubber ring is formed. After the synthetic resin pipe A is cooled, the main spindle 6 is rotated reversely, each of the split pieces 3 is contracted in the diameter thereof, the female die 1 is opened and taken off. Thus, the forming of the socket is finished.
