Embodiment 1
[0031] Embodiment 1 is shown in Fig. 1: a kind of steel shell of poor thickness of battery, and it is the hollow cylinder that positive electrode head 1 is closed, shell mouth 3 expands and opens, and the outer surface of hollow cylinder is cylindrical surface, and the middle section of hollow cylinder 2 The thinnest wall thickness is 0.18mm, which is smaller than the 0.25mm wall thickness of the positive electrode head 1 and the shell mouth 3 .
[0032] The thickness of each part of the steel shell of the existing alkaline battery with equal thickness structure is 0.25mm, and the thickness of the steel shell of the battery is reduced from 0.25mm to 0.18mm under the premise of maintaining the strength requirement; The inner cavity space of the casing is increased, and the volume of the cylinder is increased by 4%, thereby increasing the filling amount of the active material, improving the discharge performance of the battery, and prolonging the service life.
Embodiment 2
[0033] Embodiment 2 is shown in Fig. 2-3: a production process of a steel case with a different thickness of a battery is processed sequentially along the following stations on a multi-station automatic punching machine;
[0034] [1] According to the size required by the steel shell blank, the raw material is punched and cut into a disc and shallow stretched into a bowl shape;
[0035] [2] Transition station, no action;
[0036] [3] Shallow stretching, the first time to reduce the diameter of the blank and increase the height;
[0037] [4] Shallow stretching, the second time to reduce the diameter of the blank and increase the height;
[0038] [5] Retain the wall thickness of the positive head 1, stretch the hollow cylinder, and reduce the wall thickness of the middle section 2 of the hollow cylinder;
[0039] [6] Deep drawing the hollow cylinder, reducing the diameter, increasing the height, and reducing the wall thickness of the middle section 2 of the hollow cylinder;
