摘要： PROBLEM TO BE SOLVED: To improve thermal efficiency in heating an aluminum material and to improve a response speed and precision in temp. management in a heating unit used for joining, forming, heat treatment, etc., of an aluminum material. SOLUTION: A heater means 34 is arranged behind a forming jig 22 constituting a pressure applying face against an aluminum material, further, a reflector plate 36 is arranged behind the heater means 34. By this method, the forming jig 22 is heated by a direct radiation transfer from the heater means 34, in addition, the nearly whole heat rays discharged from the heater means 34 are reflected by the reflector plate 36 to be guided to the forming die 22.

摘要： PROBLEM TO BE SOLVED: To achieve improvement of joinability and dimensional accuracy by applying effective pressing pressure over the whole to even the aluminum material having a large area with respect to a press device for executing joining, forming, heat treatment or the like of the aluminum material. SOLUTION: The pressing pressure is applied to a forming jig 22 comprising a pressing surface 16 to the aluminum material 20 through plural pressurizing shafts 30a-30f and also at least either of a load control mechanism for individually independently controlling the pressing pressure which is respectively transmitted to the forming jig 22 with these pressurizing shafts 30a-30f and position control mechanism for individually independently controlling pressing positions which are respectively transmitted to the forming jig 22 with these pressurizing shafts 30a-30f is arranged.

摘要： PROBLEM TO BE SOLVED: To provide a vacuum heating device capable of preventing any operation rate from being deteriorated, and preventing any heating defective from being manufactured by facilitating countermeasures to the omen of the deterioration of a thermo-couple for measuring a high heating temperature in a heating block. SOLUTION: When the measured temperature of a heating block 27 of a first sintering chamber 2 of a vacuum heating device 10 obtained by a thermo- couple 31 reaches the set temperature of heating, and oscillates beyond the fixed temperature range, a process is controlled so that the deterioration signal of the thermo-couple can be issued, and that the heating can be automatically stopped. Also, carbon materials sintered in a temperature 3000 deg.C is used for heat insulating materials 28 of the heating block 27, and the part in the heating block 27 of a high purity aluminum insulating tube 32 of the W.Re system thermo-couple 31 for measuring the heating temperature is covered with a heat insulating material 28' for heat barrier for protecting it from the emitted heat of a bar-shaped heater 22. Also, W.Re system wires 31' and 31" are loosely bounded and fixed to a W supporting tool 35 with a Ta wire 36.
