圆钢自动下料机的设计【说明书 CAD图纸 开题报告 中期报告 实习报告 外文翻译】

摘  要
 钢管自动下料机床是带式输送机托辊钢管切断、两端倒角一次自动完成的专用设备，该机床自动化程度高、加工精度高，如送料，定位，夹紧，倒角，切断依次进行，一次就能满足钢管的加工精度，不需要辅助加工，并且安装调试方便。该设备采用的是硬质合金刀（YT5系列刀具），其硬度，耐磨性，耐热性都很好，切削速度远比高速钢快得多。液压系统中使用了双联泵供油，保证了运动速度，切断采用进口调速出口被压装置，使切断速度可调、工作稳定。钢管加工过程，由“自动送料—送料到位—夹紧—夹紧到位—进刀—进刀到位—自动落料—放松退刀—退刀到位—自动送料”循环进行，大大提高工作效率，并能适应大批量生产加工。本产品在生产中应用可以提高产品质量和经济效益，降低劳动强度。
 此次的设计主要是针对金属管材进行加工的切管机，完成的工作主要是下料机结构简图、主轴箱体和装配图的设计。包括传动装置的设计和计算，其中有电动机的选择，传动方案的拟订，各轴的转速，功率和转矩的计算。总体结构的设计，其中有各轴尺寸的设计，各主要传动件的结构尺寸的设计。并且针对以上的设计计算进行了详细的校核。最后通过得到的数据，绘制了装配图、结构简图和装配图。然后又针对各主要基本件，绘制了2张零件图。

Abstract
Steel pipe to be automatic feeding machine is of belt conveyor idlers cut off both ends, steel pipe Angle pouring a automatic completion of special equipment, this machine a high degree of automation, processing precision is high, such as feed, orientation, clamping and chamfering, to cut off the last out, one at a time can meet the machining precision of the steel tube, don't need to assist processing, installation and debugging is convenient. This equipment use is hard alloy knife (YT5 series tools), its hardness, wear resistance, heat resistance are all very good, high speed steel paper cutting speed than much faster. Hydraulic system used in double pump oil supply, ensure the movement speed, cut off the import export be pressure to speed device to make the cut speed adjustable, working stability. Steel pipe processing process,from "automatic feed-feed place clamping clamping in place feed feed in place to be automatic blanking relax recede cutter knife in place back automatic feed"cycles, and greatly improve the work efficiency, and can adapt to mass production and processing.This product can be used in the production process to improve product quality and economic efficiency, reduces the labor intensity.
This is designed to carry on the processing of metal pipes cut pipe bender, complete the main job is feeding machine structure diagram, spindle box and the design of assembly drawings. Including the design and calculation of transmission device, including the choice of motor, transmission scheme of the draft, the axis of rotation speed, torque and power calculation. General structure design, including the axis of the size of the design, the main transmission parts of the design of the structure size. And according to the design and calculationof the detailed check. Finally, through the data retrieved, mapped the assembly drawing, structure diagram and the assembly drawing. And then on the main basic parts, painted two to drawing.
