Description

一种新型挤橡机螺杆
技术领域
本实用新型属于电线电缆制造设备领域，特别涉及一种新型挤橡机螺杆。 
背景技术
挤橡机是电线电缆生产线上的核心设备，用于在铜导体外部挤出橡胶外皮。螺纹部分是挤橡机的重要部件，其作用是使胶料随螺纹部分旋转运动渐变为直线运动，向机头方向推移，并与机身配合，压缩生热、软化搅拌、混合胶料。螺纹部分的螺纹段自进料至出料可以分为喂料段、塑化段及均化段三部分，以往使用的挤橡机螺纹部分由于结构设计不尽合理，存在挤出速度慢、适用橡胶原料范围小等不足。 
发明内容
本实用新型的目的在于克服现有技术的不足，提供一种结构合理、挤出速度快、适用橡胶原料范围大的新型挤橡机螺杆。 
本实用新型解决其技术问题是通过以下技术方案实现的： 
一种新型挤橡机螺杆，由螺纹部分及传动部分构成，螺纹部分自进料至出料分为喂料段、塑化段及均化段，其特征在于：所述的喂料段包括均匀输送喂料段及位于靠近传动部分一侧所增加的输送喂料前段，该输送喂料前段由四头螺纹形成四个螺纹槽。 
而且，所述的螺纹部分直径为90-150mm，所述喂料段的有效长度为225-320mm，所述输送喂料前段的螺距为40-56mm，所述输送喂料前段的导程为160-224mm，所述输送喂料前段的螺纹槽深度为15-24mm。 
本实用新型的优点和有益效果为： 
1.本新型挤橡机螺杆结构简单，制作容易。 
2.本新型挤橡机螺杆，制有输送喂料前段，其具有较大螺距，加大了胶料供给，提高挤出效率。 
3.本新型挤橡机螺杆结构设计科学合理，具有结构简单、制作容易、挤出速度快、适用范围大等优点，是一种具有较高创新性的新型挤橡机 螺杆。 
附图说明
图1为本实用新型结构示意图。 
具体实施方式
下面通过具体实施例对本实用新型作进一步详述，以下实施例只是描述性的，不是限定性的，不能以此限定本实用新型的保护范围。 
一种新型挤橡机螺杆，由螺纹部分5及传动部分6构成，螺纹部分自进料至出料分为喂料段、塑化段2及均化段3，塑化段及均化段均为双头螺纹。其创新之处在于：所述的喂料段包括均匀输送喂料段1及位于靠近传动端一侧所增加的输送喂料前段4，匀速喂料段为双头螺纹，除有效长度较小外，其他特性参数不变。增加的输送喂料前段由四头螺纹形成四个螺纹槽。 
上述输送喂料前段的螺纹参数与螺纹部分直径进行匹配。螺纹部分直径为90-150mm，所述喂料段的有效长度为225-320mm，所述输送喂料前段的螺距为40-56mm，所述输送喂料前段的导程为160-224mm，所述输送喂料前段的螺纹槽深度为15-24mm。 
具体的优选匹配特性参数如下： 
Figure BDA00002077592900021
本实用新型通过将喂料段在原有双头螺纹的基础上增加四个螺纹槽，加大了其胶料供给，提高挤出效率。塑化段、均化段的特性参数可以不变，也可以通过对塑化段、均化段有效长度和深度合理调整，进一步使其挤出产量提高，并对适应各种橡胶材料范围加大。 
尽管为说明目的公开的本实用新型的实施例和附图，但是本领域的技术人员可以理解，在不脱离本实用新型及所附权利要求的精神和范围内，各种替换、变化和修改都是可能的，因此本实用新型的范围不局限于实施例和附图所公开的内容。
