AI Technical Summary

Technical Problem

Existing ultra-fine copper wire drawing machines are prone to wire breakage due to increased resistance to copper wire movement caused by wear of the drawing die during long-term use.

Method used

Design a wire breakage prevention structure, including a sliding connection bearing block and a wire breakage prevention unit in the groove of the mold support plate. The wire breakage prevention unit consists of a slider and a half module. The half module can automatically close to form a complete mold hole, reduce sudden changes in copper wire tension, and replace worn molds in time.

Benefits of technology

It effectively avoids wire breakage during the drawing process of ultra-fine copper wire, ensuring production continuity and stability, reducing equipment costs, simplifying the structure, and adapting to different production environments.

Abstract

本发明涉及超细铜线生产技术领域,提供了一种超细铜线拉丝生产防断线结构,包括拉丝机,所述拉丝机前侧位于两个拉丝卷筒之间设有模具撑板,所述模具撑板的顶部沿铜线拉丝方向开设有若干个相互平行且排列整齐的滑槽,所述滑槽内滑动连接有用于承载拉丝模的承载块。本发明克服了现有技术的不足,设计合理,结构紧凑,在拉丝过程中,当防断线单元前一承载块上拉丝模孔磨损严重,铜线直径超出预设公差时,后一承载块因受铜线拉力过大沿滑槽运动距离超出预设值,此时防断线单元的两个半模块能自动合拢,形成完整拉丝模孔对铜线拉细,降低后续承载块所受拉力,有效避免超细铜线在拉丝过程中断丝情况的发生,保障生产的连续性和稳定性。
