Abstract
Profile milling flying saw is one of the most advanced flying saws in the modern world, its tracking system driven by servo motor and its sawing system using profile milling method. This flying saw has many advantages, such as simple control system, less jamming signal, higher dimensional accuracy, flat section and convenient operation. Since the profile milling flying saw was launched, it has been put into a wide applications. The paper gives a brief introduction of the working principles of tracking system and makes a specific analysis of its motion. The movement patterns of saw cutting round pipes and square pipes are given in the sawing system and the mathematical models of saw cutting square pipes are established by analysis. In fact, the methods mentioned above have been used in practice. The dimensional accuracy of sawing welded pipe has reached the requirements of British BS standards and come up to the world advanced level.
Highlights
Profile milling flying saw is important equipment that could be used in the welded pipe production line
When the tracker and the welded pipes are at synchronized operation, the sawing device will imitate the shape of the welded pipe to cut with a specified length [1]
The motor system of the flying saw mainly consists of two parts: tracking system and sawing system
Summary
Profile milling flying saw (known as flying saw for short) is important equipment that could be used in the welded pipe production line. After finishing the process of the formation of the welded pipe, the tracker of the flying saw tests the production speed of the welded pipe on-line. Tracking system achieves synchronous motion with welded pipe and control dimensional accuracy of sawing welded pipe. The flying saw control system is a kind of typical multi-axis control system and takes advantage of the MC206 controller which is based on Trio to control each phase of the movement of flying saw [2], especially in the realization of the S curve movement and in the process of cutting for imitation shape cutting of square pipe.
