切管机设计
摘要：切管机主要用于加工各种用途的管件，主要包括各种材料的金属管件，本次设计的切管机所加工的管件主要是直径在3/8″～4″之间。
 本文档设计的切管机，完成的工作主要是切管机中减速箱、滚子、机体等的设计。其中包括确定工艺方案、传动装置的设计和计算（包括电动机的选择、拟定传动方案、各轴转速、功率和转矩的计算、传动机构的设计与计算等）。在对上述各项进行了详细的强度校核之后，根据已有的经验公式，确定了各个零件之间的相互尺寸。在最后绘制出了装配图、部件图以及部分零件图
 本文设计所完成的切管机主要用于车间中对管件的切屑加工，对于提高生产效率，减轻工人的劳动强度有着积极的意义。

The design of tube cutting machine

Abstraction: Tube cutting machine mainly being used in processing various functional tube parts ,primarily includes varieties material`s  metals tube parts . This time  the designed  Tube cutting machine essentially process the tube parts which diameter between 3/8"~4".
   
     The task of this time designed Tube cutting machine is chiefly  comprises the design and of deceleration case , roller ,organism, and so on.  Besides, the task also includes  the others several steps,such as :settle the technology craft program;the design and calculation of transmission installation ; (includes the selection of electric motor ; formulate the transmission program; the rotational speed of each axle; power and the calculation of Torque ; the  design and calculaton of the transmission mechanism etc).  After  detailed intensity proofread  for all kinds the above--methioned , according to the already experienced--formula, the mutual dimension among each components being fixed .  Finally ,  draw the assemble chart; components chart as well as portion  spare parts chart.
 
    The designed Tube cutting machine  mainly used on cutting and processing for tube  part in the work shop  .  To some extent, the design has positive significance  in improving productivity and lightening the workers labor intensity.
    
Key words:   tube cutting machine    transmission parts        design     calculation
