摘要： PROBLEM TO BE SOLVED: To obtain a bending method for a hollow double tube by which the energy consumption is reduced to a minimum and a cycle time is made short. SOLUTION: A method consists of a process to insert a cylindrical bag body 7 having the flexibility and pressure resistance into a gap 3 of a hollow double tube 1, a process to press-inject a fluid 8 into the bag body 7 and a process to apply bending stress to the hollow double tube 1 while the fluid 8 is press- injected in the bag body 7 so as to bend the hollow double tube 1. Because of the use of the bag body 7 and the fluid 8 press-injected in the body bag 7 as the packing material, the heating/cooling process is not required as compared to water (ice) as the packing material and the energy consumption for heating/cooling is eliminated and a cycle time is shortened. Further, the generation of the dust and spattering are not incurred as compared to the packing material of the sand or steel ball. Further, the fluid 8 as the packing material has no deterioration accompanying the use, the continuous use is made possible to reduce the cost in this respect.

摘要： PURPOSE:To provide a pouring and discharging furnace having compact structure and high working efficiency and thermal efficiency. CONSTITUTION:The pouring and discharging furnace 2 has a three dimensional structure vertically arranging a discharging furnace 4 and a pouring furnace 3 and arranges a storing part 5 on the floor 7, and the bottom part of the storing part is formed with an inclining surface projected to the pouring furnace 3 downward, and a valve 9 is arranged. Hot blast heated with a duct heater 18 through a duct 16 is blasted mainly into the discharging furnace 4 with an axial fan 17 to heat the discharging furnace and a part of the hot blast is blasted into the pouring furnace 3 to hold the temp. in the pouring furnace. Filler in a bending pipe-like work 6 supported with a discharging carriage 10 in the discharging furnace 4 is melted, discharged and stored into the storing part 5. Then, the valve 9 is opened and the filler is poured into the inner parts of straight pipe-like works 1 supported with a filling carriage 12 positioned at the lower part of the valve.
