본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (2)

합성수지관의 단부를 연화하여 확대 시키고 패킹 감삽 요홈을 형성하는 연결부 성형방법에 있어서, 연화된 합성수지관의 단부가 삽입되는 만드렐(3)에 요홈(5)을 형성하여 요홈내에 원륜상 패킹(1)을 끼우고 돌조(7)을 갖는 지지관(6)을 삽입하여 패킹이 뒤로 밀리지 않도록 고정시킨 후 합성수지관(8)의 연화된 단부를 씌워서 패킹(1)의 부위에 요홈(11)이 형성되게한 후 지지관(6)을 빼고 냉각하여 패킹이 삽설된 연결부를 성형함을 특징으로 하는 합성수지관의 연결부 성형 방법.In the method of forming a connecting portion for softening and enlarging an end portion of a synthetic resin pipe and forming a packing subtraction groove, a groove 5 is formed in the mandrel 3 into which the end of the softened synthetic resin pipe is inserted, thereby forming a circular packing 1 in the groove. Insert the support tube (6) having the protrusion (7) to fix the packing so that it does not push back, and then cover the softened end of the synthetic resin tube (8) to form the groove 11 in the portion of the packing (1) Method of forming a joint portion of a synthetic resin tube, characterized in that for forming the connecting portion in which the packing is inserted by removing the support tube (6) and cooling. 외단부(3'')의 직경이 동체부(3')의 직경보다 좁게 형성된 만드렐(3)로 된 연결부 성형장치에 있어서 만드렐(3)의 동체부(3')에 패킹 지지요홈(5)를 형성하고 만드렐(3)의 동체부(3') 외측에 지지관(6)을 전후진할 수 있도록 착설하되 지지관(6)의 전진시 그 선단이 요홈(5)의 후연부와 일치되게 착설하고 지지관(6)에 관체 선단 지지용 돌륜(7)을 돌설하여서된 합성수지관의 연결부 성형장치.In the connecting part forming apparatus of the mandrel 3 formed with the diameter of the outer end 3 '' being narrower than the diameter of the body 3 ', a packing support groove is formed in the body 3' of the mandrel 3; 5) is formed so that the support tube 6 can be moved forward and backward on the outer side of the fuselage part 3 'of the mandrel 3, but the tip of the recessed part of the recess 5 is advanced when the support tube 6 is advanced. A device for forming a joint portion of a synthetic resin pipe, which is installed in accordance with the structure and protrudes a support wheel (6) to support the front end of the tube body. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
