Abstract
本发明提供蓄电池角型端子，包括铅合金--融化--浇注毛坯，将浇注后的毛坯通过挤压模具冷压挤压成型，再通过修剪挤压毛边成型；挤压模具的压力为63T-100T。本发明冷压角型端子仅仅将浇注后的毛坯通过挤压模具冷压挤压成型，改变的方式虽然简单，但是带来的技术效果完全不同，零件组织结构致密，内部断面无气泡，内外表面光洁；63T-100T的挤压模具压力，能够使挤压后的毛坯成品率达到100%。通过致密度检验、耐热烘试验、浸泡试验及金相组织分析，都证明了冷压端子致密度好于压铸端子，能够起到较好的防爬酸效果。
Description
技术领域
本发明涉及蓄电池的连接件，具体是蓄电池角型端子。
背景技术
蓄电池角型端子成“L”拐角形状，其一端用来连接蓄电池的电极，另一端在和导线连接，如图1所示，图中1端和连接蓄电池的电极，另一端2在和导线连接；目前用于蓄电池的角型端子都是压铸成型，因为致密度不足，如图2所示，内外部存在气孔，在受热后气孔膨胀形成气泡，导致爬酸的现象；在蓄电池行业的售后故障件失效模式中，端子爬酸是一个典型的失效模式。
目前蓄电池角型端子采用铅合金--融化--压铸成型的工艺方法，由于蓄电池角型端子的“L”拐角形状，铅坯在挤压过程中流动性差，单方向冷挤压的方法难以一次成型。
发明内容
本发明为了解决蓄电池角型端子的组织结构，使其组织结构致密，内部断面无气泡，解决爬酸的现象，并且使其内外表面光洁，特提出蓄电池角型端子。
为此本发明的是技术方案为，蓄电池角型端子，包括铅合金—融化—浇注毛坯，其特征在于：将浇注后的毛坯通过挤压模具冷压挤压成型，再通过修剪挤压毛边成型。
进一步的改进在于：挤压模具的压力为63T-100T。
有益效果：
本发明冷压角型端子仅仅将浇注后的毛坯通过挤压模具冷压挤压成型，改变的方式虽然简单，但是带来的技术效果完全不同，零件组织结构致密，内部断面无气泡，内外表面光洁。
63T-100T的挤压模具压力，能够使挤压后的毛坯成品率达到100%。
通过致密度检验、耐热烘试验、浸泡试验及金相组织分析，都证明了冷压端子致密度好于压铸端子，能够起到较好的防爬酸效果。
附图说明
图1是本发明的产品示意图。
图2是压铸成型的金相组织分析示意图。
图3是通过挤压模具冷压挤压成型后金相组织分析示意图。
具体实施方式
本发明如图1、3所示，挤压模具冷压挤压成型后金相组织分析示意图。
首先将铅合金放入融化炉内融化。
2根据挤压量匹配毛坯的形状和尺寸，做成模具浇注成毛坯。
3将毛坯放入挤压模具中，将产品一次冷压挤压成型，挤压模具的压力为63T-100T。
4制作工装，修剪产品挤压毛边。
Claims (2)
