摘要： PROBLEM TO BE SOLVED: To improve the limiting molding height of a molded product with a simple means in an overhang molding method. SOLUTION: In the overhang molding of a blank W such as a resin-laminated aluminum foil, a preliminary molding in a dome shape is carried out by supplying pressure fluid from a punch 20 side to the forming blank W an then, the main molding is performed in a required shape using the punch 20. The pressure fluid is fed from one or more fluid flowing holes 23 disposed, for example, on the top panel 22 of the punch 20.

摘要： PURPOSE:To prevent the deformation of a molded superplastic metallic sheet at the time of releasing and taking out this sheet out of metallic molds for superplastic molding in superplastic molding for molding the superplastic material. CONSTITUTION:This superplastic molding device has the metallic mold 2 enclosing the circumference of a metallic mold surface 4a with a wall part 4b and a cap part covering and hermetically sealing the metallic mold 2 in the state of holding the superplastic metallic sheet to be molded between this cap part and the metallic mold 2. Plural grooves 3 spaced from each other in the longitudinal direction of the wall part 4b of the metallic mold are formed in the corner parts formed of the upper surface of the metallic mold and the flanks on the metallic mold surface 4a side of the wall part 4b of the metallic mold. The molding is executed by heating the superplastic metallic sheet at a temp. at which the metallic sheet exhibits superplasticity and pressurizing the inside of the cap part segmented from the inside of the metallic mold 2 by the superplastic metallic sheet. The molding part molded in correspondence to the metallic mold surface 4a and the reinforcing part molded with ribs for reinforcement by the grooves 3 are formed on the superplastic metallic sheet, by which the deformation at the time of releasing and taking out is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a method for surely, highly reliably and rapidly manufacturing a heat transmit plate of a flat type having an intricate structure bonding metallic plates to each other with high yield by using electric resistance welding, then subjecting the plate to tube expansion operation and an optimum refrigerator using the same. SOLUTION: The plates 1 and 2 are inserted between a lower die 61 on the inner side of a pedestal 63 and an upper die 60 of an inner side of a pressing seat 62 and are subjected to the tube expansion operation by admitting compressed air between the plates 1 and 2 subjected to the resistance welding at required points. At this time, the peripheral edges of the metallic plates 1 and 2 are previously widely provided with non-tube expansion parts 13 and 14 and after the plates are securely held by pressers 64 and 66 for the upper die and pressers 65 and 67 for the lower die, the plates are subjected to the tube expansion operation. If the heat transmit plate 100 is formed in the manner described above, the bulging of the heat transmit plate 100 is made uniform over the entire part and such situation that the sectional area of a refrigerant flow passage 36 is varied depending upon places by the partial abnormal shrinkage does not occur any more and the heat transmit plate having high reliability may be obtained.

摘要： PROBLEM TO BE SOLVED: To reduce the wall thickness, the weight and the cost of a superplastic forming mold subjected to temperature and pressure. SOLUTION: A lower mold 16 is integrally joined to a lower divided furnace 30 by mounting the both ends of the lower mold 16 on a bracket 35, 35 through a heat insulating piece 36, 36 and joining them with a bolt 37, 37. Similarly, an upper mold 13 is integrally joined to an upper divided furnace 40 by mounting the both ends of the upper mold 13 on the bracket 42, 42 through the heat insulating piece 46, 46 and joining them with a bolt 47, 47. Therefore, this reinforcing reduces effectively the rigidity, the weight of the mould and its cost.

摘要： PROBLEM TO BE SOLVED: To provide a technology to preferably clamp a die for superplasticity forming. SOLUTION: In figure (a), in die clamping, the A pressing faces 39... and the B pressing faces 39... shown in black colored are set to high clamp force, the C pressing faces 39... and the D pressing faces 39... shown in void are set to low clamp force. A figure (b) shows setting of a clamp means when heating is progressed somewhat, a high pressure gas is blown between upper/ lower dies 11, 13 for blow forming and a die inside pressure is increased somewhat, that is, the clamp force at the C pressing faces 39... and the D pressing faces 39... apart from the center are increased, the whole A-D pressing faces 39 are strongly pressed. Thus, both of the suppression of generation of thermal stress and the sufficient increase of die clamp force are satisfied.

摘要： PROBLEM TO BE SOLVED: To provide a technique that can reduce a loss of thermal energy and can raise productivity in superplastic forming. SOLUTION: Blow molding is carried out with a left forming die 60 of Figure (a), and a next blank 71 is hung on a right arm member 33. In Figure (b), immediately after the blow molding has been finished, an upper die 62 is raised as indicated by arrows (4), the arm member 33 is entered into the forming die 60 as indicated by an arrow (5), and the blank 71 is dropped on a lower die 64 (arrows (6) in Figure (c)). Then a formed part 72 sticks to the upper die 62. Thus, a coolant gas is sprayed on a lower surface of the formed part 72 through balloon nozzles 34. The formed part 72 contracts with this forced cooling and is off the upper die 62, and is mounted on molding pedestal parts 35 of the arm member 33 (an arrow (7). As a result, cycle time can be shortened and the next blow molding becomes possible to be started before the forming die 60 gets cold.
