耳机麦克风用金属软管的制作方法及其产品 技术领域
本发明涉及到耳机麦克风用金属软管，尤其是涉及一种耳机麦克风用金 属软管的制作方法及其产品。 背景技术
目前， 现有关于耳机麦克风用耳线， 其结构大多是将金属导线放入 PVC 塑胶壳内， 这种结构的耳线， 其抗压强度低， 多次使用后易变形且易折断， 较硬， 弹性不好， 不方便使用。
而制作这种耳线的工艺，其是要分幵成型内圈和外圈，效率较慢，另外， 老工艺生产产品的公差较大， 并不能自动裁切， 需软管成型后再手工裁切； 再得， 老工艺只可以生产 5mm以上的软管。 发明内容
本发明针对上述现有技术的不足所要解决的技术问题是： 提供一种耳机 麦克风用金属软管的制作方法及其产品， 其可克服上述缺陷， 使用方便， 弹 性好， 抗压强度高。
为了达到上述目的， 本发明所采用的技术方案是：
一种耳机麦克风用金属软管的制作方法， 其分为以下步骤：
第一步为进料： 首先采用两侧双导线轮使钢丝同步进料成型， 在铁丝进 料的导线轮部分加装压线轮， 将铁丝压制成三角形；
第二步为成型： 利用成型模具的弯曲导板使钢丝在轴心上成型， 在此同 时利用压入模具将己经在进料端压成三角形的铁丝压入钢丝成型的弹簧中 从而形成软管；
第三步为自动切断：预先设定红外感测器的距离， 当软管的成型长度达到 设定长度， 触动红外感测器， 则红外感测器激发软管裁切器将软管裁成需要 长度。
其第一步主要采用同步变速器使两边进料速度一致并匀速。
其第二步是利用变频器控制成型速度。
用上述的制作方法制成的耳机麦克风用金属软管，配合金属导线使用，所 述的金属导线外包覆一高碳钢丝或不锈钢丝，在该高碳钢丝或不锈钢丝外再 包覆一层钢丝或铜丝。
所述金属导线外的高碳钢丝或不锈钢丝的横截面成形为圆形。
所述高碳钢丝或不锈钢丝外包覆的钢丝或铜丝横截面成形为方形。
所述的高碳钢丝或不锈钢丝是间隔绕在金属导线的外表面，钢丝或铜丝是 沿其间隔缠绕在高碳钢丝或不锈钢丝上。
本发明的有益效果是： 本制作方法首次开发了可对软管进行一次性成型 和裁切的设备和模具， 使其用于软管成型的钢丝和铁丝可以一次成型， 从而 提高了生产效率； 首次利用先进的模具和工艺将软管的公差控制在正负
0.05mm内， 因此新的一次成型模具系统可以精确的控制公差和软管裁断长 度；新工艺和设备可以生产出外径 2.0mm以上的软管，填补了国内国际空白。 用本制作方法生产的耳机麦克风用金属软管， 由于两钢丝或铜丝相互间隔缠 绕， 因此其软度比较好， 即其韧性好， 且可根据内的金属导线有弯曲定型的 效果， 较习用品相比， 使用也比较方便， 经久耐用， 抗用强度高； 另外， 其 外部可根据需要电镀成各种颜色， 看起来也较为美观； 另外， 由于进行了新 的工艺生产， 其组成软管的材料选择可多样化， 即其可选择钢丝、 铁丝、 铜 丝及不锈钢丝。 附图说明
