Abstract

本实用新型公开了一种镍氢、镍镉、镍锌等圆柱形电池的拉伸钢壳。在钢壳头部0～10mm处进行拉伸，使底部壁厚比拉伸端的头部壁厚厚0.03～0.1mm。采用本实用新型的电池钢壳，它减小头部拉伸端的钢壳壁厚，增大钢壳内部空间，利于高容量电池制作。

Description

一种圆柱形电池钢壳
技术领域
本实用新型涉及一种镍氢、镍镉、镍锌等圆柱形电池的拉伸钢壳。
背景技术
传统圆柱形电池使用直径为13.9mm、壁厚为0.2mm、高度为49.0mm的钢壳，该钢壳的生产大致流程依次为卷绕、滚槽、注液、封口。上述钢壳由于内部空间的限制，只能制作的容量低电池产品，导致高容量电池无法装配。
实用新型内容
本实用新型的目的在于提供一种圆柱形电池钢壳，它增大了钢壳内部空间，利于高容量电池制作。
为了达到上述目的，本实用新型由以下的技术方案来实现。
一种圆柱形电池钢壳，其特征在于：该钢壳使用直径为13.9mm～14.5mm之间的任何尺寸，壁厚为0.10～0.2mm的任何尺寸，高度为49mm至51.5mm的任何尺寸，在钢壳头部0～10mm处进行拉伸，使底部壁厚比拉伸端的头部壁厚厚0.03～0.1mm。
所述的钢壳壳口部份壁厚增加。
本实用新型有益效果在于，采用本实用新型的电池钢壳，它减小头部拉伸端的钢壳壁厚，增大钢壳内部空间，利于高容量电池制作，为保证壳口滚槽时不会出现将钢壳滚穿，因此将钢壳壳口部份壁厚增加，将钢壳高度增高，利于高容量电池制作，而又通过后期处理将电池整形至相同高度。
附图说明
图1为本实用新型结构示意图
具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步详细地描述。
如图1所示的一种圆柱形电池钢壳1，该钢壳1使用直径为13.9mm至14.5mm之间的任何尺寸，在本实施例中，钢壳1使用直径为14.1mm。壁厚为0.10-0.2mm的任何尺寸，高度为49mm至51.5mm的任何尺寸，在本实施例中，高度为51.2。采用上述尺寸的钢壳1后，在钢壳头部的0～10mm处进行拉伸，使底部壁厚比拉伸端的头部壁厚厚0.03～0.1mm。在本实施例中，拉伸端的头部所示壁厚为0.14mm。在本实施例中，钢壳1壳口部份壁厚为0.2mm，比壳身的壁厚增加，保证壳口滚槽时不会出现将钢壳滚穿。该钢壳的生产大致流程依次为卷绕、滚槽、注液、封口、墩封。该钢壳可用于镍氢、镍镉、镍锌等圆柱形电池上。
