The utility model is characterized in that : the transverse sections of shaped sections to be severed determine that the edged cutting tools are fixed on the rotation axes and rotate along 其主要特点是：由被切型材横截面决定其切削刃形状的刀具被安装在转动轴上，随转动轴转动。
The axial line of the rotation axes forms an angle with the moving direction of the shaped sections ranging from 70 degree to 110 degree 该转动轴的轴线与型材运动方向成70和110度之间，刀具在随转动轴转动过程中完成切断任务，实现按照需要的设定长度进行管材或其它型材的不停机定长切断。
Making a great swing is about maintaining the natural balance of the body through the swing , not moving the balance point from left to right like many players are being told to do 良好稳定的挥杆要求在整个挥杆的过程中保持身体转动轴的稳定和身体的平衡，整个身体没有大幅度的左右侧向滑动。
Dismantle distributor lid , rotate shaft to make casing 1 of touch off gear to point to the iron core center of hall sensor . at this time distribution head is positioned at casing 1 of distributor 拆下分电器盖，转动转动轴，使触发轮1缸缸口正对霍尔传感器铁芯中心，此时分火头在分电器1缸位置处；

Firstly , in order to treat the local weakened effect of the crack on the shaft , the equivalent line - spring model is built . then the constitutive equations are derived and the flexibility model of the rotating shaft is discussed . based on the lagrange equations , the non - linear dimensionless differential equations of the single rotor system with the disk and crack located at an arbitrary position of the shaft are obtained 首先为处理裂纹对轴的局部削弱作用，提出了等效线弹簧模型，推导了线弹簧弹性本构关系，获得了裂纹转动轴的柔度模型，然后，应用lagrange方程建立了盘和裂纹处于轴任意位置的无量纲的单盘转子系统的非线性运动控制微分方程。
