摘 要
切割机分为火焰切割机、等离子切割机、激光切割机、水切割等。激光切割机的效率最快，切割精度最高，切割厚度一般较小。等离子切割机切割速度也很快，切割面有一定的斜度。火焰切割机针则是对于厚度较大的碳钢材质。水切割，又称水刀切割，是一种利用高压水流切割的机器。在电脑的控制下能任意雕琢工件，而且受材料质地影响小。
自动切割相对手动和半自动切割方式来说，可有效地提高板材切割的效率、切割质量，减轻操作者的劳动强度。目前在我国的一些中小企业甚至在一些大型企业中使用手工切割和半自动切割方式还较为普遍。
本文针对工厂的实际生产需求，提出了设计题目。设计出符合要求的板材切割机，并对机床的机械系统、气动系统、控制系统等方面进行了全面设计。
机械系统设计中，本文首先设计出加工过程中所需要的皮带型号、动力部分、导轨、机械滑台等。此外，文中也对工件加工中所需的刀具以及工作台进行了简单的设计。
气动系统设计中，本文先对加工过程中所需的压力及杠杆原理进行综合利用，并以此为基础，计算出此设计中所需要的气缸的缸径，并选择出适合要求的气缸型号。
最后，希望此次设计的板材切割机能满足预期的设计要求，并能在实际应用中取得良好的效果。

Abstract
Cutting machine, plasma cutting machine is divided into flame, laser cutting machine, water cut, etc. Laser cutting machine for efficiency is highest, the fastest, precision cut thickness general lesser. Plasma cutting machine cutting speed is quick, cutting surface has certain Angle. Flame cutting carbon based on the qualitative thick.Water cut, also known as water knife cutting, is a kind of using high pressure water cutting machine. Under the control of the computer can carve any artifact, but also affected by the material quality little .
Automatic cutting relative to manual and semi-automatic cutting way, can effectively improve the efficiency of plate cutting, cutting quality, reduce the labor intensity of operators. At present, some small and medium-sized enterprises in our country and even in some big companies using manual cutting and semi-automatic cutting way is also more common.
Based on the actual production factory, puts forward the design demand topic. Designed to meet the requirements of sheet metal, and the mechanical system of machine tools, pneumatic system and control system of the overall design etc.
Among the Mechanical system designing, this paper first designed the processing belt model, dynamic part of the process need, guide rail, mechanical sliding table and so on. In addition, the article also required in the processing of cutting tools and the workbench has carried on the simple designed.
Pneumatic system design, this paper first needed to process the pressure and the lever principle for comprehensive utilization, and based on this, the design is calculated in the cylinder cylinder diamethe needs, and choose the suitable requirements of cylinder type.
Finally, I hope this design sheet cutting function meets the design requirements and expectations in application of good effect.、
