Description

一种汽车电池连接铜片生产工艺
技术领域
本发明涉及电池连接铜片生产技术领域,具体属于一种汽车电池连接铜片生产工艺。
背景技术
由于铜的导电率好,所以铜被广泛的使用作为导电介质。汽车电池会使用铜片作为正负极的导电连接材料。现有的电池连接铜片生产都是直接对铜片冲压成型,然后进行表面处理和热处理,由于铜片较脆,在冲压成型的过程中容易冲压跑偏,造成次品,不但浪费了铜料,还耽误正常的生产工时。
发明内容
本发明的目的是提供一种汽车电池连接铜片生产工艺,在铜片冲压之前对铜片利用石灰水和含有30%乙醚的甲醇溶液进行浸泡处理,冲压成型前对铜片进行快速淬火处理,冲压后铜片进行热处理,处理效果好,提高了铜片的坚硬度,进一步提高铜片的可加工性。
本发明采用的技术方案如下:
一种汽车电池连接铜片生产工艺,包括以下步骤:
(1)预处理:将铜片放入80~100℃的石灰水中浸泡3~5小时,然后再使用50~60℃的含有30%乙醚的甲醇溶液浸泡1~2小时;
(2)干燥处理:将经过预处理的铜片送入烘干室烘干;
(3)冲压成型:将铜片利用冲压机冲片;
(4)表面处理:将冲压后的铜片用砂纸打磨,再放入到盐水池中盐浴1~2小时,盐水温度维持在60~80℃;
(5)热处理:将铜片送到加热炉内加热处理,炉温维持在400~500℃;
(6)冷却:将经过热处理的铜片利用风机强制冷却;
(7)检验:质检员检验铜片的外观、尺寸;
(8)包装:最后对铜片进行打包入库。
进一步的,冲片成型前对铜片进行快速淬火处理,淬火温度为150~200℃,淬火时间为5~10秒。
进一步的,干燥处理的过程中,间歇向铜片表面喷射醋酸溶液,每次喷射时间为10秒。
与已有技术相比,本发明的有益效果如下:
本发明在铜片冲压之前对铜片利用石灰水和含有30%乙醚的甲醇溶液进行浸泡处理,冲压成型前对铜片进行快速淬火处理,冲压后铜片进行热处理,处理效果好,提高了铜片的坚硬度,进一步提高铜片的可加工性。
