The Control System Design For Steel Pipe Flat Head Machine In The Spiral Submerged Arc Welded Pipe Producing Line

According to spiral welded pipe products of my company, the steel flat head machine is a equipment for chamfering, de-burring and edge milling on the surface of spiral seam welded pipe ends. In this paper, the feeding control system of steel flat head machine is designed with servo control technology, from the processing effect of the equipment in the welding plant, two ends of the steel pipe groove surface machining quality is improved and it is easy to meet the requirements of production process.First, through access to information, accumulating experience and combined with the company’s steel flat head machine, this paper clarifies the research status of upgrading process and improvement of mechanical system and electrical control system in the process of renewal, and introduces the current the domestic and foreign flat machine future development and development status. Based on the using of company’s steel flat head machine use, author accesses to a large number of materials related to mechanical system or electric control system of steel flat head machine, to fully understand the current technology updates about the steel flat head machine. Secondly, according to the spiral seam welded pipe diameter and wall thickness, the design requirements and processing range for the steel flat head machine is determined, and it can meet all kinds of pipe end face processing requirements in the maximum range. At the same time, this paper analyses working principle and electric control system of steel flat head machine. And then, the hardware for electrical control system of steel flat head machine is combined reasonably, and the hardware structure, function, characteristics and parameters of key electric control system are discussed in this paper, and it is designed that the controller of the master station connected with the servo drive from the station. Finally, the machine realized the host structure and the auxiliary mechanism order movement according to the processing request, the overall plan of the program is designed, the hardware configuration, network configuration and PLC program are carried out in the STEP7 programming software tool. Some PLC programs are verified by simulation software, the related configuration and parameter setting of S120 driver based on STARTER software are carried out, so that servo controllers work and communication.Compared with other companies facing machine electric control method, electric control mode has been further improved, mechanical feeding device with a servo motor completes the conversion between quick and slow, without needing two motor and reducers for speed conversion, it improves the mechanical structure.In this paper, steel flat head machine is practical application on spiral welded pipe production line in Shandong Shengli Steel Pipe Limited Company, and achieved good results.
