汽车用PVC管生产自动切割机的设计

摘要：各种切割机在汽车制造业的应用十分广泛，为了不断的提高产品的质量，各种切割机的改造升级迫在眉睫。一方面要控制设备成本不能过高，另一方面对切割机算法程序的快捷效率有着一定的要求。汽车用PVC管切割机配备了自动化较高的自动换刀系统，加工精度提高了，机械的效率上升了，材料的切面变得光滑了，因此产品的质量变得更加优质。在理论研究和实地考察实验的基础上，PVC管切割机采用从国外进口的铣刀，这种铣刀的刀口十分锋利，排屑十分顺畅，这样可以避免粘刀情况的发生。同时可以使PVC管材切边光滑无毛刺，更加的经久耐用，一方面提高了生产效率，一方面提高了产品质量。基于PLC的切割机控制系统，当前比较先进的微机控制技术的采用，使切割机实现了工业生产交流电的无级调节速度，整个切割机耗电量明显降低，而且可以随着负荷的大小而变化。PVC管切割机在自动化流水线上的充分运用能提高工厂的生产效率，尤其实在汽车生产领域，减轻工人的劳动强度，为实现车间无人化提供了可靠的条件。

Design of Automatic Cutting Machine for Production of PVC Pipe for Automobile

Abstract： Various cutting machines are widely used in the automobile manufacturing industry, in order to continuously improve the quality of products, the transformation and upgrading of various cutting machines is imminent. On the one hand, to control the cost of equipment can not be too high, on the other hand, the cutting machine algorithm has a certain speed efficiency requirements. PVC pipe cutting machine is equipped with automatic high automatic tool changing system, the machining accuracy is improved, the efficiency of the machine is increased, the plane of the material becomes smooth, so the quality of the product becomes more and more quality. On the basis of theoretical research and field experiment, PVC pipe cutting machine adopts from foreign imports of milling cutter, the cutter blade is very sharp, very smooth swarf discharging. Only in this way can avoid the occurrence of sticking to the knife. At the same time can make PVC pipe cutting edge smooth without burr, more durable, on the one hand to improve the production efficiency, on the one hand to improve the quality of products. Cutter control system based on PLC, the advanced microcomputer control technology adopted in, make the cutting machine to achieve the industrial production AC stepless speed regulation, the cutting machine power consumption decreased significantly, but also with the changes in the size of the load. PVC pipe cutting machine in an automatic production line of making full use of to improve the production efficiency of the factory, especially reality in the field of automobile production, reduce the labor intensity of the workers, to achieve unattended workshop provides reliable conditions.
