Abstract

PURPOSE: To provide a pipe expander with prevents damage on pipes due to drop of a press member and improves working efficiency and safety by means of a member so provided as to stop a press rod and the press member.
CONSTITUTION: A guide sleeve 11 fitted into a pipe body 2 is fixed with a screw 11a positioned on the pipe expansion medium side engaged with a screw section 11b opposite to the guide sleeve 11 and a screw section 4b on a pressure rod 4 passing through screw sections 4b and 4c provided on the tip side of the pressure rod 4. A notch 4 is formed between the screws 4a and 4b to confine the repeated rupture to notch 4a and screws 4b and 11b. The screw 4c are positioned between the screws 11a and 11b. The screw 4c come in contact with the screw 11a thereby preventing the slipping off of the guide sleeve 11 due to damage to the rod 4 or the screws 4b and 11b.
