Title: Method and apparatus pipe expanding
Inventor: YASUDA TAKEO
IPC: B21D39/20
Filed: 1980-10-14
Abstract: PURPOSE: To prevent seizure applying drawing pressure caused by difference of acting face and giving lubrication by pressing lubricating liquid into the small diameter side of a plug and communicating it to the rear large-diameter part.  
     CONSTITUTION: When hydraulic oil is sent by pressure from a hose 6 by operating a pressure oil source pump 7, the hydraulic oil passes through a hole 8 and pressed out between the small diameter part 10 of a plug 9 and a pipe 13 from an opening 11 for pressing in. At this time, it actuates a motor 21 by initially set power, and applies working force to pull out the pipe by connection of a cap 16 and a clamp ring 17. The pipe 13 is then pulled out to the right side relatively. Meantime, expanding action is generated between the plug 9 and the pipe 13 and an expanded pipe 14 is formed. On the other hand, the pressure oil pressed out to the small diameter part 9 of the plug 9 leaks from a microclearance between the plug 9 and the inner face of the pipe 13 and makes lubrication. Accordingly, a pressure chamber 18 is also filled with the hydraulic oil and differential pressure acts by the difference in area corresponding to subtraction of sectional area of a supporting rod 4 before and behind the plug 9, and pulling force is applied.

CONSTITUTION:A valve 4 is closed before cleaning, the valve 3 of a horizontal pipe 1B and a stopper 1C at the end on the downstream side are opened to discharge water in a riser pipe 1A, and the valve 3 is closed thereafter. An appropriate amt. of cleaning soln. 8 is injected into the liq. reservoir part 7 on the upstream side while regulating the level with a level regulator 6, and then a cleaning compressed gas is sent into the pressure accumulating part 9 from a delivery pipe 5C of a gas compressor 5. When preparation is finished, the valve 3 is opened, and the soln. 8 is allowed to flow instantaneously into the horizontal pipe 1B by the pressing force retained by the compressed gas in the pressure accumulating part 9.
