摘要： PROBLEM TO BE SOLVED: To permit stabilized brazing connection by forming a uniform brazing material layer and contrive the improvement of a resistance to corrosion as well as heat exchanging performance by a method wherein projections are formed on both side rims of a multi-hole tube and the outer surface of the multi-hole tube is coated with the brazing material layer. SOLUTION: An aluminum multi-hole tube 1, having projections 12 on both side rims 13, is formed through extrusion forming while the outer surface of the multi-hole tube 1 is coated by a brazing material layer 5 upon extrusion. The thickness of the brazing material is preferably within the range of 2-23% of the thickness of the multi-hole tube 1. The penetrating parts 11 of the brazing material layers 5 are formed in the projections 12 by providing the projections 12 and they will not be arrived at the inside of the multi-hole tube 1 whereby there is no fear of leakage of fluid even when a heat exchanger, connected through brazing, is exposed under a corrosive atmosphere. On the other hand, the formed projections 12 serve the role of fins whereby the heat dissipating performance of the heat exchanger is increased.

摘要： PROBLEM TO BE SOLVED: To provide a multi-layer clad stock capable of uniformly being heated in both a core and a skin even by the induction heating, and capable of excellently preventing generation of swelling during the extrusion. SOLUTION: An extruded billet 1 is provided with a core 3 having a cylindrical large diameter part 3a and a cylindrical small diameter part 3b. A plate of the thickness equal to the difference in radius of the large diameter part 3a and the small diameter part 3b is bent along the outer circumference of the small diameter part 3b to constitute a skin 5. The MIG welding is executed to each end of the skin 5 (a weld zone 6), and the metal to constitute the skin 5 is melted into the metal to constitute the core 3 to melt both metals to each other. No definite interface between the core 3 and the skin is present in the weld zone 6. When the induction heating is executed, not only the magnetic flux passing through the skin 5 and the magnetic flux passing through the core 3 is formed to uniformly heat the core 3 and the skin 5. Because the skin 5 is cooled and shrunk after the welding and the clearance between the skin and the core 3 becomes small, generation of the swelling can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent the tip of a mandrel from deflecting by preventing the stress applying the bending to the tip toward the center from being exerted on the tip of the mandrel. SOLUTION: A flat elliptic opening part 9 corresponding to the outer periphery of a perforated pipe is formed in the contact surface 7a of a female die with a male die 3. A mandrel 13 having many tips 13a corresponding to the holes of the perforated pipe is provided on the male die 3 and entry parts 15 are formed in the upper and lower parts of the mandrel 13. When metal is introduced from the other end face 3b of the male die 3 with the male die 3 and the female die 7 combined, the metal is introduced into the circumference of the tip 13a only from the vertical direction of the mandrel 13 through each entryport 15. Then, the stress attempting to bend the tip 13a toward the center is not exerted.

摘要： PURPOSE:To produce cylindrical compact without any traverse crack by closing both ends of rubber cylindrical body, in which powdery raw material is packed, by covering bodies preventing mutual approach of the covering by an outer cylindrical member and working hydraulic pressure to the rubber cylindrical body through liquid passing-through holes arranged in the outer cylindrical member. CONSTITUTION:The Al (alloy) powdery raw material 4 or compacting is packed in the rubber cylindrical body 6 and both end opening parts of the cylindrical body 6 are closed water-tightly by the rigid covering bodies 8, 10. Outer flanges 8a, 10a are integrately formed on the covering bodies 8, 10 and the outer cylindrical member 14 is inserted between the outer flanges to prevent shrinkage of the cylindrical body 6 toward axial direction. The outer cylindrical member 14 is constituted by half dividing bodies 14a, 14b and suitable number of the liquid passing-through holes are arranged at each body 14a. 14b. High pressure liquid is invaded through these liquid passing-through holes, and the prescribed pressurizing force is worked to the outer circumferential face of the cylindrical body 4 to compress the law material 4 toward diameter detection at the prescribed compressing force. Then, the mutual approach of the covering bodies 8, 10 are prevented by the outer cylindrical member 14 and displacement of the. rubber cylindrical body 6 toward axial direction is prevented. By this method, the traverse crack in the powder compact is prevented, and treatment of the compact is facilitated.
