Description

双螺杆挤出机的螺旋轴结构
技术领域
本发明涉及一种双螺杆挤出机的螺旋轴结构，特别地，涉及一种通过使凸肩部结构为锥形部与锥形环的组合，以减轻制造螺旋轴时的坯料重量的新的改进。
背景技术
作为一直以来使用的这种双螺杆挤出机的螺旋轴结构，例如，可以列举专利文献1公开的结构。
即，上述专利文献1的螺旋轴结构是如图4及图5所示的结构。
即，图5中附图标记1所表示的是用来切削加工制造螺旋轴2的螺旋轴坯料，其结构为，在该螺旋轴坯料1上，其两端设置一对吊装孔3、4，通过各吊装孔3、4能够搬运该螺旋轴坯料1。
通过切削加工，由所述螺旋轴坯料1形成连接部5、基部6、凸肩部7和螺旋件插入部8，所述连接部5与来自图中未示出的驱动马达的减速器相连接；所述基部6与该连接部5一体形成；所述凸肩部7形成于该基部6的下游处；所述螺旋件插入部8与该凸肩部7连接，用来插入多个螺旋段。
此外，如图4所示，将上述螺旋轴2并列内置在图中未示出的气缸内，从而构成双螺杆挤出机。
现有技术文献
专利文献
专利文献1：日本专利特开2005-22091号公报
发明内容
（一）本发明要解决的技术问题
由于现有的双螺杆挤出机的螺旋轴结构为如前所述的结构，因此存在如下技术问题。
即，由于现有的螺旋轴2，其基部6与螺旋件插入部8之间的凸肩部7是一体形成的，因此，在旋转轴2中，作为外径，该凸肩部7的外径最大。
另外，与此相对，外径最小部分是占据最大轴向长度的，用来插入多个螺旋段的螺旋件插入部8。
因此，如图5所示，由于用由纵向柱状体构成的螺旋轴坯料1，切削加工制作螺旋轴2，因此该螺旋轴坯料1的外径必须与凸肩部7的外径相等，或比其大，在该状态下由旋转轴坯料1制造旋转轴2时，尤其是从相当于比凸肩部7直径小的螺旋件插入部8的部分产生大量不需要的坯料，在成本方面及坯料方面来看也浪费，结果，对于螺旋轴2的完成重量，坯料的重量增大。
（二）技术方案
本发明的双螺杆挤出机的螺旋轴结构，其在至少包括具有用来与减速器连接的连接部、基部及螺旋件插入部的结构的双螺杆挤出机的螺旋轴结构中，在所述基部与螺旋件插入部之间设置锥形部，在所述锥形部上配接锥形环，所述锥形环形成凸肩部。
另外，所述结构为，所述锥形部的外径与所述基部的基部外径相等或小于基部外径。
（三）有益效果
基于本发明的双螺杆挤出机的螺旋轴结构形成如前所述的结构，因此能够得到如下效果。
即，在至少包括具有用来与减速器连接的连接部、基部及螺旋件插入部的结构的双螺杆挤出机的螺旋轴结构中，在所述基部与螺旋件插入部之间设置锥形部，在所述锥形部上配接锥形环，所述锥形环形成凸肩部，由此，由于在基部与螺旋件插入部之间由螺旋轴坯料制成的仅为锥形部，因此与现有的凸肩部相比，外径变小，能够缩小螺旋轴坯料的外径，能够减轻螺旋轴坯料的重量及形状缩小，能够实现坯料成本的降低及因加工时间缩短带来的加工费用的减少。
另外，实际上与现有结构相比，其效果是，能够使坯料重量减轻30%，机械加工时间减少20%。
因此，包含坯料费用与加工费用的成本降低40%左右。
另外，通过使锥形部的外径与所述基部的基部外径相等或小于基部外径，使得在由螺旋轴坯料制造的螺旋轴的全长上，最大外径仅为基部，与现有的螺旋轴相比，能够使螺旋轴坯料的外径变小，并能够降低螺旋轴坯料的原料成本。

图2是图1的A部放大图。
图3是表示切削加工一根图1螺旋轴的状态的螺旋轴坯料的说明图。
图4是表示现有的双螺杆挤出机的螺旋轴结构的俯视剖视图。
图5是表示切削加工图4螺旋轴的状态的螺旋轴坯料的说明图。
具体实施方式
本发明的目的是提供一种双螺杆挤出机的螺旋轴结构，其是通过使凸肩部的结构为锥形部与锥形环的组合，以能够减轻制造螺旋轴时的坯料重量。
实施例
下面，结合附图，对本发明的双螺杆挤出机的螺旋轴结构的适当的实施方式进行说明。
此外，对于与现有例相同或相当的部分，使用相同附图标记进行说明。
图3中附图标记1所表示的是用来切削加工制造螺旋轴2的螺旋轴坯料，其结构为，在该螺旋轴坯料1上，其两端设置一对吊装孔3、4，通过各吊装孔3、4能够搬运该螺旋轴坯料1。
在所述螺旋轴坯料1上，通过切削加工，形成连接部5、基部6及锥形部20，所述连接部5与来自图中未示出的驱动马达的减速器相连接；所述基部6与该连接部5一体形成；所述锥形部20形成在该基部6下游与螺旋件插入部8之间。此外，该锥形部20以图1的A部分表示，并在图2中放大表示。
所述锥形部20的外径与基部6的基部外径6a相等，或者小于基部外径6a。
如前所述，所述锥形部20的外径与基部外径6a相等，或者小于其，因此在螺旋轴2上最大外径部分为基部外径6a，因此，能够使螺旋轴坯料1的外径与现有的螺旋轴坯料1的外径相比显著减小，同时，也能够使其重量显著减轻。
另外，如图1及图2所示，在所述锥形部20的外周上，配接锥形环21，该锥形环21具有与该锥形部20的外面形状一致的里面形状，利用该锥形环21，进行插入到螺旋件插入部8中的各螺旋段（图中未示出）的定位及固定，使其能够进行与现有的凸肩部7等同的作用。此外，通过用锥形部20构成配接锥形环21的部分，能够避免应力集中，防止损坏等。
因此，由于螺旋轴2的最大外径为基部6的基部外径6a，因此，通过使螺旋轴坯料1的外径与基部外径6a一致，能够实现显著减轻螺旋轴坯料1的重量。
工业实用性
本发明的双螺杆挤出机的螺旋轴结构，由锥形部与锥形环构成现有的凸肩部，从而能够使螺旋轴坯料的外径显著减小，能够实现成本的显著降低。
