摘要： PURPOSE:To simply form neck-in parts with different diameters on both ends of upper and lower parts of the can drum, at the time of manufacturing the can vessel possessed of the neck-in part of the upper end with the larger diameter than that of the neck-in part of the lower end, by contracting the lower end part of the can drum, then bulging the center section of the can drum. CONSTITUTION:A core 2 with an equal diameter of the contracting diameter is inserted into a lower opening 1a of the can drum 1 formed by rounding a sheet to connect its free ends together, an annular die 4 is disposed on the outer periphery of the opening 1a to move in the direction of the arrow along the core 2, to perform a drawing work for the lower end opening part 1a of the cam drum. Then, the die 6 equipped with a hollow part 6a adjusted with the bulging shape of the can drum is disposed outside the center section of the can drum, and a projecting part 7b bulged by the punch 7 pressing the inner surface of the can drum 1 and adjusted with the hollow part 6a of the die 6 is formed. In this bulging work on the lower part of drum 1 is formed the neck-in A drawn one step comparing to the central part 5 of drum 1, while on the upper part of drum 1 is formed the neck neck-in B with a larger diameter than A.

摘要： PURPOSE:To manufacture a can body with an uniform height around the periphery after bulging, by previously providing a side seam margine of a blank can drum and providing cut-off corners on its neighborhood. CONSTITUTION:The blank can drum 15 is cylindrically rounded and both sides thereof are lap sealed to form a side seam 14 to product a straight can drum 16. Then, a part 13 in a longitudinal part of the straight can drum 16 is bulged by using a split mold project in the radial direction to reduce the height of the can to form the can drum 12. The upper ends (cut-off parts) 21 of the lap seal margines 17, 18 on the both sides of the can drum 12 are removed. In this manufacturing process, elongations of the side seam 14 and its neighborhood are small to cause the reduction of the can height compared with the other parts. Thus the bulged can with the uniform height around the periphery is easily manufactured.

摘要： PURPOSE:To form a can having different diameters, capable of meeting the needs for the diversifying shapes of a can, by containing a forming process for bulging a part in the axial direction of a can body having a basic diam. and a forming process for beading a part of the other part in the axial direction of the basic-diam. part. CONSTITUTION:A rectangular blank material of can-body is rounded into a cylindrical shape, and a side seam is formed by sealing both side-ends, and a straight cylindrical can-body 12 having a basic diam. DO larger than the minimum diam. D1 is formed. Next, a part of h2-a in the lengthwise direction is bulged by using segmental dies, rubber, or hydraulic pressure, to obtain a bulged can-body 12b. Next, a part of o-h2 in the lengthwise direction is radially reduced by beading into a prescribed shape whose minimum diam. is D1, to obtain a can-body 12C. The body 12C is provided with a bottom 13 or a cover 14 by crimpling, to complete a can having different diameters.
