Abstract

本实用新型公开了一种铜包铝漆包线拉丝模，涉及一种拉丝模，本实用新型的目的设计一种拉出丝的光洁度高且拉丝中断丝率低的铜包铝漆包线拉丝模。本实用新型的技术方案是，一种铜包铝漆包线拉丝模，包括工作区和定径区，所述工作区的锥度α为18－22度，长度L2为1－1.4d，定径区的直径为d，其长度L3小于d，上述d为铜包铝线的直径。本实用新型用于漆包线生产。

Description

一种铜包铝漆包线拉丝模
技术领域：
本实用新型涉及一种拉丝模，特别是一种铜包铝漆包线拉丝模。
背景技术：
铜包铝漆包线由于导电性能较好和价格低得到广泛使用，由于这种导线是铜包铝的复合线材，传统的铝线或铜线拉丝模的进口润滑区、成形工作区和定径区的锥度、长度参数不能足铜色铝漆包线的成形要求，拉丝中断丝率高，线的光洁度低。
发明内容：
本实用新型的目的设计一种拉出丝的光洁度高且拉丝中断丝率低的铜包铝漆包线拉丝模。本实用新型的技术方案是，一种铜包铝漆包线拉丝模，包括工作区和定径区，其特征在于：所述工作区的锥度α为18-22度，长度L2为1-1.4d，定径区的直径为d，其长度L3小于d，上述d为铜包铝线的直径。本实用新型与现有技术比较具有拉出的丝的光洁度高和断丝率低的优点。
附图说明：
附图是本实用新型铜包铝漆包线拉丝模的纵剖面结构示意图。
具体实施方式：
结合以上附图对本实用新型作详细说明，为了降低拉丝模拉线过程中的断丝率、提高产品的光洁度，对拉丝模的工作区的锥度α、长度L2，及定径区的长度L3制成：α＝18-22度，L2＝1-1.4d，定径区的直径d为铜包铝线的直径，L3<d，进口润滑区和出口区的锥度β和长度L1为常规拉丝模的参数。采用这种拉丝模拉出的钢包铝线的光度高且在拉丝过程中断丝极少发生。
