| PROBLEM TO BE SOLVED: To provide a negative electrode can for a battery which can give a fixed part of a positive electrode lid to the negative electrode can of the battery with sufficient strength, and to provide its manufacturing method. SOLUTION: A cylindrical negative electrode can 1 has a sidewall and extends along a center axis 17, where the sidewall has an upper end 2 as a heavy-walled part relatively large in thickness and a sidewall thin-walled part 3 relatively smaller in thickness than the thickness of the upper end 2. The upper end 2 is located on the end of the sidewall. The sidewall thin-walled part 3 is a part other than the upper end 2 of the sidewall. In the sidewall, a distance L3 between the periphery surface of the upper end 2 and the center axis 17 is equal to a distance L3 between the periphery surface of the sidewall thin-walled part 3 and the center axis 17. On the other hand, in the sidewall, a distance L1 between the inner surface of the upper end 2 and the center axis 17 is shorter than a distance L2 between the inner surface of the sidewall thin-walled part 3 and the center axis 17.

| PROBLEM TO BE SOLVED: To form with a small force by pressing the blank material whose whole periphery of a recessed disk is surrounded by a flank and the thickness of the disk is gradually increased in the outside direction from a disk center to form a tapered shape, and integrally forming a dome part and a flange part. SOLUTION: The whole periphery of the blank material 10 is surrounded by the flange 11. The thickness of the disk part of the blank material 10 is gradually increased by a tapered surface 13 from a center 0, and a thickened part 14 is formed. After heating the blank material 10 to a hot forming temperature, the blank material 10 is mounted on the die 16 of a press device. After putting the thickened part 14 in the opening part of the die 16, the flange 11 is placed on the die 16. By pushing the upper die 15 of the press device in the blind surface 12A of the recessed part 12 of the blank material 10, flange part 17C and dome part 17A are simultaneously formed. It is swelling work to decrease the thickness of each part of the recessed part 12, however, since the tapered surface 13 has been formed, the blank material 10 is formed without an underfill. Since the upper die 15 is smaller than the dome part 17A, working can be performed by a small press force without ironing. | ||||||

| PURPOSE: To enable swaging without crack and groove at a corner part in the inside of an outer periphery by bending a swaging part from a base part to one direction to form an L shape cross section having a prescribed width and forming the inner and the outer surfaces into a prescribed size as closed forging state. CONSTITUTION: In a plate material 11 punched to a disk-state, the center part except a swaging part 11a is held and fixed with a fixed table 12 and a pressing plate 13. A positioning pin 14 is arranged in the center part of the fixed table 12 to position the plate material 11. The swaging part 11a is swaged from the outside to the center side by synchronously rotating a roll die and the plate material 11 and formed as arrowhead-state cross section. Successively, in the swaging, the swaging part 11a is bent to the other side surface while using the one side surface B of the plate material 11 as the base and formed as the close forging state so as to become the bent width C of the formed product. By this method, the corner parts in the inside of the swaging part can be formed without developing the crack and the groove. | ||||||
| 94 | Method for forming shaft from metallic plate | JP3834495 | 1995-02-27 | JPH08229616A | 1996-09-10 | ISERI MITSUHIRO; HAYASHIZAKI KAZUAKI; HINO YUTAKA |
| PURPOSE: To integrally form shafts the length, accuracy of the outside diameter, perpendicularity, etc., of which are enough ensured from a metallic plate in the arbitrary position of the metallic plate by executing backward extrusion of projecting parts with a punch and die after forming the projecting parts by executing forward extrusion of the metallic plate by press working. CONSTITUTION: First, the half die cutting or forward extrusion of a material having volume necessary to form the shafts 7 is executed by pressing by using the punch. Next, the projecting parts 4 of the metallic plate 1 which are made by half die cutting or forward extrusion are compressed with the punch 5 and die 6 and the shafts 7 are worked by executing backward extrusion. At this time, since the material of the projecting parts 4 is replaced by the shafts 7 and the shafts 7 are elongated in the moving direction of the punch 5, the metallic plate 1 is in a state lifted from the upper surface of the die 6. By collectively, forming the shafts having the same height in plural places, the plural shafts having the same height are elongated by backward extrusion and variation in the amount of lifting and inclination of the metallic plate are prevented.
