摘要： PROBLEM TO BE SOLVED: To prevent dioxin pollutants from flying outside a structure by sucking the dioxin pollutants with a suction fan, even when surrounding dioxin pollutants fly when the irradiation of laser is performed. SOLUTION: A suction fan 14 is disposed at a suction port 2a of a structure 2 and a vacuum is caused in the structure 2 to suck dioxin pollutants 3, which prevents the dioxin pollutants 3 from flying outside without requiring large-scale working such as covering the whole of equipment. A laser part 5 is provided to irradiate the dioxin pollutants 3 with laser 4 so that the dioxin pollutants 3 are automatically heated over the entire area of the internal surface of the structure 2. This eliminates the need for disassembling the structure 2, for working by a worker in the bad environment and for spraying of water as pretreatment.

摘要： PURPOSE:To accurately perform pressure control and to attain a high speed for forming by providing a hydraulic control cylinder in a part of the hydraulic chamber of an opposed hydraulic forming machine. CONSTITUTION:A blank 20 is held on a die 6 by a blank holder 15, and a punch 18 is lowered for abutting on the blank 20 to perform drawing. Water 8 in the same volume as the punch 18 and the blank 20 plunging into the hydraulic chamber 4 is moved to a lower hydraulic chamber 5B through a port 10. Consequently, a movable ring 9 inside the pressure control chamber 5 is pushed up. The ring being directly connected to a cylinder device 11 structured in the lower part, a hydraulic pressure or a gas pressure is supplied to or drained from the lower chamber 11C of the cylinder device 11 so as to control the load over the movable ring 9, and the hydraulic chamber 4 is controlled for a prescribed pressure.

摘要： PURPOSE:To attain high speed for forming and to facilitate the control of pressure for each part by providing a floating piston in a part of the forming hydraulic chamber of a opposed hydraulic forming machine and controlling the hydraulic pressure through a high pressure gas. CONSTITUTION:A punch 20 is lowered to be abutted on the blank 35 on a die 4 and drawing is performed. At this time, the die 4 and a blank holder 11 are raised for the volume for which the blank 35 is plunged into the forming hydraulic chamber 2. The oil 15 in an upper hydraulic chamber 14 is absorbed as the floating piston 16 is raised. In a fluid chamber 17 above the floating piston 16, a high pressure gas 19 is controlled by a high pressure gas controlling device 30. In the stably controllable rate of flow, the gas is faster approximately ten times the fluid, and therefore the punching speed and the number of press stroke are greatly enhanced.

摘要： PURPOSE:To prevent the outer deformation on the web face of a bar steel by pinching the flange and web of the bar steel with the grooved lower die plate of which the fulcrum metal die is rotatable and changeable, a back die and upper die in the bar steel bending by a fulcrum metal die couple and center metal die. CONSTITUTION:A bar steel 1 is bent by the transition of a pair of fulcrum metal dies 2 arranged at a distance in horizontal direction and a center metal die 3. The flange 8 of the bar steel 1 is pinched by the lower die grooved plate 27 of the fulcrum metal die 2(20) and a back die 23 and the web 5 of the bar steel 1 is pinched by the plate 27 and upper die 25. The grooved lower die plate 27 supported by a pin 28 to the lower die 22 is changeable by the web 5 size of the bar steel 1 and adaptable for the rotation by the pin 28 for the bend of the flange 8 by the bending of the bar steel 1 as well. The generation of the outer deformation of the web surface thereof is therefore prevented surely irrespective of the size of the bar steel 1.
