Description

一种热镀锌异形钢丝的生产设备 技术领域
[0001] 本发明涉及到一种异形热镀锌钢丝的生产设备。 具体为一种热镀锌异形钢丝的 生产线装置。 即一种以辊模为产品最终定型模具， 生产截面积为椭圆形或其它 幵关的热镀锌钢丝的生产线设备。
背景技术
[0002] 现有的热镀锌钢丝生产普遍采用的工艺流程：
[0003] 原材料 （盘条） 一拔丝一椭圆形截面积的裸钢丝一热镀锌一截面积为椭圆形的 热镀锌异形钢丝。
[0004] 采用上述方法生产截面积为椭圆形 1的异形热镀锌钢丝吋， 首先根据产品的防 腐性能要求计算出钢丝表面镀锌层的厚度 σ， 然后计算出镀锌前的裸钢丝的截面 积为椭圆形 2。 生产吋， 拔丝将盘条的截面积缩小至椭圆形 2。 热镀锌处理吋控 制钢丝表面的锌层厚度 σ， 生产出截面积为椭圆形 1的异形热镀锌钢丝。
[0005] 在上述的生产过程中， 因为截面积为椭圆形的热镀锌异形钢丝的截面积不是圆 形， 所以拔丝和热镀锌的收线机必须采用工字轮设备。 而工字轮收线存在 3个主 要弊端， 首先是收线吋钢丝每卷的重量较小， 由此因收线盘重量小而导致物流 成本高和生产效率低。 其次是收线工字轮盛满钢丝后必须停止拔丝、 镀锌生产 才能更换新的空载收线工字轮， 因此无法实现拔丝、 热镀锌生产线的连续作业 ， 同样使生产成本提高。 最后关键是在拔丝和热镀锌的收线过程中， 不停转动 的工字轮使操作人员无法对正在生产的热镀锌钢丝进行在线质检， 无法及吋排 除质量隐患， 影响生产效率及产品质量。
[0006] 此外， 采用现有技术的拔丝成型设备， 如果将截面形状为圆形的盘条拔成椭圆 形状的钢丝， 需要经多道工序成型， 设备庞大， 占地面积也大。
技术问题
[0007] 本发明针对上述现有技术存在的不足， 为了提高生产效率、 节约生产成本和保 证产品质量， 幵发出一种热镀锌异形钢丝的生产线装置。 问题的解决方案
技术解决方案
[0008] 一种热镀锌异形钢丝的生产线装置， 包括放线设备， 拔丝设备， 热镀锌设备， 收线设备及前处理设备， 其特征是所述的各设备按如下顺序相衔接构成生产热 镀锌异形钢丝的生产线装置： 第一放线设备-前处理设备-热镀锌设备-第一收线 设备 -第二放线设备-辊模成型设备-第二收线设备，
[0009] 所述的热镀锌异形钢丝的生产线装置按如下顺序步骤生产热镀锌异形钢丝： 第 一步原料盘条进行预处理； 第二步经拔丝设备将盘条拔出截面为圆形的裸钢丝 ； 第三步将所述圆形截面裸钢丝入热镀锌设备中进行表面镀锌处理， 得到截面 积为圆形的热镀锌钢丝并由旋转式收线机收线； 第四步将上述圆截面热镀锌钢 丝入辊模成型设备得到截面为椭圆形状的热镀锌钢丝并由旋转式收线设备收线 入库。
[0010] 所述的一种热镀锌异形钢丝的生产线装置， 其特征是所述的第一放线设备为工 字轮放线机， 所述的第一收线设备为第一旋转式收线机， 所述的第二放线设备 为倒立式放线机， 所述的第二收线设备为第二旋转式收线机。
发明的有益效果
有益效果
[0011] 本发明是一种以辊模为关键设备生产截面积为椭圆形的热镀锌异形钢丝的生产 线设备， 放弃现有技术的拔丝成型后再镀锌的工艺， 采用拔丝 -镀锌 -辊压成型的 新工艺， 保证了产品质量， 减少了拔丝成型设备。 采用象鼻子收线机进行收线 和 /或梅花撒线机进行收线。 使得在拔丝和热镀锌过程中实现大重量的收线、 更 换收线盘不需要停止生产、 在线监测质量成为可能。 滚 （辊） 模的压线辊轮在 钢丝的变形过程中与钢丝产生滚动摩擦， 摩擦力远小于采用眼模拉拔吋产生的 相对滑动摩擦力， 热镀锌圆形截面钢丝在变形成椭圆形截面钢丝的过程中， 镀 锌层和裸钢丝的变形量和发生吋间几乎一致， 避免了在最终变形吋， 长轴和短 轴方向的锌层分布不均匀和锌层与裸钢丝脱落形成的质量缺陷。
