Description

一种电缆双层共挤用机头
技术领域：
本实用新型涉及电缆加工技术，尤其涉及一种电缆双层共挤用机头。
背景技术：
双层共挤机头，是由企业机电车间自行设计，自主研发的一款性能优越的电缆挤塑成形模头。原先的机头及模具的材料选用不合理，机械制造时通过热处理调质工艺使得各个零部件在装配以及拆卸后，多次组装中经常会变形，机械强度达不到实际工作环境的需求导致易磨损、易损坏。
以前采用圆柱式型腔结构，使用过程中经常有焦料、死料滞留在模头的型腔内，导致电缆的绝缘层和护套层会有击穿点产生。挤塑模具经常出现偏心，挤塑成型的绝缘层和护套层质量受到影响。
实用新型内容：
为了弥补现有技术的不足，本实用新型的目是提供一种电缆双层共挤用机头，结构设计合理，产品质量得到提升，机头使用寿命延长。
本实用新型的技术方案如下：
电缆双层共挤用机头，包括壳体，所述的壳体为筒体形状，其特征在于：所述的壳体内孔为锥形孔，锥形孔内从大端到小端依次穿插有外锥形的外导胶管、内导胶管、进线导管，其中内导胶管与外导胶管贴合固定于锥形孔大端的壳体外壁，进线导管端部顶住所述的内导胶管的外壁，所述的锥形孔小端设有挤出模具，有调节螺栓穿过壳体外壁顶住所述的挤出模具外壁，有端盖顶住旋合安装于锥形孔小端顶住所述的挤出模具。
所述的电缆双层共挤用机头，其特征在于：所述的壳体、挤出模具采用材料为优质合金模具钢42CrMoAl。
本实用新型的优点是：
本实用新型结构设计合理，壳体采用锥形孔设计，挤塑模具与壳体之间设有调节螺栓便于调节偏心现象的发生，此外模具和壳体选用优质合金钢，延长了使用寿命。
附图说明：
图1为本实用新型的结构示意图。
具体实施方式：
参见图1：
电缆双层共挤用机头，包括壳体1，壳体1为筒体形状，壳体1内孔为锥形孔2，锥形孔2结构使电缆料在塑化后挤出更加流畅，挤塑的压力更加稳定，使用过程中不会再有焦料、死料滞留在模头的型腔内，锥形孔2内从大端到小端依次穿插有外锥形的外导胶管（通常为护套料导胶管）3、内导胶管（通常为绝缘料导胶管）4、导线用进线导管5，其中内导胶管4与外导胶管5贴合固定于锥形孔2大端的壳体1外壁，进线导管5端部顶住内导胶管4的外壁，锥形孔2小端设有挤出模具6，有调节螺栓7穿过壳体1外壁顶住挤出模具6外壁，有端盖8顶住旋合安装于锥形孔2小端顶住挤出模具6。
壳体1、挤出模具6采用材料为优质合金模具钢42CrMoAl，机械制造时通过热处理调质工艺使得各个零部件在装配以及拆卸后，多次组装中不会变形。挤出模具6通过高频淬火工艺使其使用性能更加优越，增强了机械强度从而不易磨损、不易损坏。
