Description

一种无屑切割机
技术领域
本发明涉及切割机领域，具体涉及一种无屑切割机。
背景技术
传统的无屑切割机，转盘旋转由旋转电机控制完成，切割进刀由液压系统或另一台电机驱动完成；进刀动作由液压系统完成，液压系统成本高，而且液压系统使用频率越高，越容易漏油，要经常维护，浪费人力和物力，影响管材的生产效率。夹紧机构用哈夫夹紧块进行夹紧；每换一个规格，就要换一套哈夫夹紧块。哈夫夹紧块是由铸铝做成的，成本高；更换夹紧块花费的时间长。每个动作都是各自独立分开完成的；结构复杂，可靠性差，成本高。
此外，由于管材的壁厚越厚，需要的切割力就越大；传统的液压切割系统对切割力的把握不好，切割时都是固定一种液压力进刀，由于管材内部产生很大的应力作用；切割厚管的时候很容易出现“白口”的现象。
发明内容
本发明解决的技术问题是提供一种无屑切割机，使其不仅结构简单，还可以根据管材厚度自动同步调节径向进刀量和转盘旋转速度，减少“白口”现象，实现无屑切割。
为解决上述技术问题，本发明采用的技术方案是：
一种无屑切割机，包括主机架，设置在该主机架上的转盘、夹紧装置和用于驱动该转盘转动的驱动电机，以及设置在该转盘上的机械切割装置，其中：所述机械切割装置包括基座、装设在该基座上的切割刀片和用于调整切割刀片径向进刀深度的进退刀调整机构，该进刀调整结构包括行星齿轮和与该行星齿轮的转动轴配合的丝杆进退刀机构，该丝杆进退刀机构与该切割刀片连接，此外，所述转盘上设有与该行星齿轮配合的内齿轮。
作为改进之一：在所述转盘径向上装设至少两套机械切割装置，其中一机械切割装置具有较长且较薄的切割刀片，其中一机械切割装置具有较短且较厚的切割刀片。
作为改进之二：所述驱动电机通过传动机构驱动所述转盘转动，该传动机构包括：设置在所述驱动电机输出轴上的主动齿轮、设置在所述转盘上并与该主动齿轮配合的转盘齿轮。
作为改进之三：所述的夹紧装置为快门式可变径夹紧装置。
与现有技术相比，有益效果是：由于本发明通过一台驱动电机同时实现了转盘转动和切割刀片进刀两个动作，而且还实现了转动和切割刀片同步协调功能，从而减少了“白口”现象，实现无屑切割。
附图说明
图1是本发明的整体结构示意图；
图2是本发明的局部结构示意图；
图3是本发明的转盘及机械切割装置的示意图；
图4是本发明的机械切割装置的结构的示意图；
图5是图4的A-A方向的剖视图；
图6是本发明的夹紧装置的结构示意图。
具体实施方式
如图1所示，本发明的无屑切割机，包括主机架，设置在该主机架上的转盘、夹紧装置1和用于驱动该转盘转动的驱动电机2，以及设置在该转盘上的机械切割装置3。
如图2所示，该驱动电机2通过传动机构驱动转盘转动，该传动机构包括：设置在驱动电机输出轴上的主动齿轮5、设置在转盘上并与该主动齿轮5配合的转盘齿轮4。
如图3至5所示，该机械切割装置3包括：基座、装设在该基座上的切割刀片9、9’和用于调整切割刀片9、9’径向进刀深度的进退刀调整机构，该进刀调整结构包括行星齿轮7和与该行星齿轮8的转动轴配合的丝杆进退刀机构8。该丝杆进退刀机构7与该切割刀片9、9’连接，此外，转盘上设有与该行星齿轮8配合的内齿轮6。
在本实施方式中，转盘径向上装设有两套机械切割装置3，其中一套机械切割装置3具有较长且较薄的切割刀片9，另一套机械切割装置3具有较短且较厚的切割刀片9’。同时，在转盘的周围设计了几把以上的切割刀，前刀薄而长，后刀厚而短的特点。先在管材的表面划开一道细细和深深的缝；然后，在利用后刀厚而短的性能，进行深切割；在前、后刀同时切割的过程中，管材产生的应力降到最小；减少了管材“白口”的现象出现。
此外，如图6所示，该夹紧装置1为快门式可变径夹紧装置。
本发明的工作原理为：当切割机接受到切割信号后，可变径夹紧块1夹紧不同规格的管材，驱动电机通过主动齿轮4带动转盘齿轮5运转，转盘开始转动。同时，机械切割装置3的行星齿轮7受到内齿轮6的被动作用力，行星齿轮7把传动力输送丝杆进退刀机构8，使得切割刀片9进行进刀动作。当切割进行时，转盘齿轮5顺时针运转，此时行星齿轮7受到固定齿轮6被动作用力，带动丝杆进退刀机构进行进刀动作，切割管材开始。根据恒功率定律，如果切割刀9受到管材的摩擦力和应力不同，则转盘转动的速度与该应力相应的调整，保证切割管材的力度，使得切出来的管材质量美观，光滑。
本发明所切割的管材的壁厚越厚时，切割刀受到的应力就越大，需要的进刀力就越大，那么行星齿轮的受到的阻力，使转盘的速度降低。但是，这样就起到转盘转动和切割进刀同步进行切割管材的效果，很好的把握好切割进刀的力量。
综上所述，由于本发明通过一台驱动电机同时实现了转盘转动和切割刀片进刀两个动作，而且还实现了转动和切割刀片同步协调功能，从而减少了“白口”现象，实现无屑切割。
