"Can body making machine, and method of forming different sizes of straightened and stretch wall cans by the same can body making machine" a can body making machine and a method of forming different sizes stretched and smooth-walled cans by the same can body making machine, wherein the can body making machine includes a ram (4), a crank (22), first and second connecting rods (21, 23) and a oscillating lever (20) connecting the crankshaft (22) to the ram (4). Different locking positions (x, z) are provided on the swing lever so that the first (primary) connecting rod is connected to alternative positions on the swing lever. the primary connecting rod (21) then rotates about an axis between the selected locking position and the pivot pin position (y) 30 on the swing lever (20). the primary rod drives the swing lever to rotate to a corresponding degree and thereby converts the rotation of the swing lever into axial movement of the ram (4) so as to move the ram by a specified stroke length. changing the position of the locking pin (25) and therefore from the pivot point to the primary connecting rod, the ram's stroke is changed.
