Abstract

PURPOSE:To obtain the subject coupling easily by working for larger diametered on end side of the short resin pipe while the other end side thereof is done so by means of a stepped die with a stopper forming ring seated on the step and a stopper forming ring is planted on the boundry of the two wronght ends. CONSTITUTION:One end side of the short pipe 1 is wrought for larger diameter up to about 1/2 the total length of the pipe by means of the die 3A with a taper 4. Then, the stopper forming ring 6C is seated on the step 10 of the stepped die 3B while the guide ring 9 with a guide taper is seated on the point closer to the die tip from the ring C. The other end side of the pipe is pushed into the die B and wrought up to almost 1/2 the total lenght and the stopper forming ring 6C is planted on the boundary 11 of the two sides thus wrought. Subsequently, the molded product planted with the ring 6C is withdrawn together with the guide ring 9 and finally the guide ring 9 is removed from the product to obtain a coupling.
