　　　便攜式數(shù)控火焰切割機用于黑色金屬板材切割，切割厚度2毫米—50毫米，切割軌跡為由直線圓弧組成的任何平面圖形。設備具有輕便、移動的特點，適合于流動作業(yè)場所。設備由移動裝置、數(shù)控裝置、割炬裝置、供氣系統(tǒng)等組成。
　　　文章簡單介紹了便攜式數(shù)控火焰切割機的總體設計及執(zhí)行機構(gòu)的設計。根據(jù)便攜式數(shù)控火焰切割機的工藝特點和其對系統(tǒng)自動化控制功能的技術(shù)要求，文章敘述了其基本結(jié)構(gòu)的設計，包括：橫向、縱向即X向、Y向移動裝置的結(jié)構(gòu)設計和調(diào)整控制設計；割炬的升降結(jié)構(gòu)設計和調(diào)整控制設計。對于整個火焰切割過程的自動化控制,本文采用工控機，實現(xiàn)了上述功能。該系統(tǒng)具有較高性價比，同時工作可靠，操作方便，極大地提高了勞動生產(chǎn)率。

Title   Then the hold type number controls the total design and the             
 Performance organization designs that the flame incises the machine            

Abstract
Then the hold type number controls the flame to incise the machine to used for the black metals plank material's incise，Incise the thickness 2 millimeters of-50, Incise the track as any flat surface sketch constitute by the straight line arc. The equipments has the easy and convenient and ambulatory characteristics，The suitable for fluxion homework place. Equipments from move the device and count to control the device, mow the torch device and provide to annoy the system etc. constitute.
Article is simple to have introduced the hold type number controls the total design and the performance organization designs that the flame incises the machine. According to its craft characteristic and its technical requirement for automation control function, article have narrated the design of its basic structure, include: the lateral and longitudinal namely X and Y locomotive structural design and adjustment control design ;as well as the cutting torch design about its rise and adjustment control design . For the automatic control of wholly flame cutting procedutal , the Industrial personal computer is adopt to carry out these function forementioned , at the same time  drawn the  diagram. This system performance very well, working reliable,operating simple ,has raised labour productivity maximumly.
