Analysis And Research Of The Profiling Flying Saw

With the rapid development of economy,the demand from national economy for steel tube is increasing everyday.As the steel tube follow-up cutting equipment on the production line,the flying saw machine has played a vital role in the production and processing of the steel tube.The research on the design of the flying saw is becoming a hot spot in academic research.In regard to the cutting of large-scale square tubes,the traditional flying saw has disadvantages of high energy consumption,low precision and poor reliability.Therefore,the developing of new profiling flying saw suitable for large square tube has become the inevitable task for the industry.This paper takes 300mm×300mm square tube as example to analyze and study the steel tube flying saw.The main contents of this paper are as follows:Design the motion process of the sawing system of flying saw Perform motion planning for the tracking system of the flying saw.After study,the sin2? method is used to track the motion.Thus the tracking task can be completed effectively while avoiding generating impact load,reduce the wearing of the motor and the whole system.Design of the sawing system for flying saw The sawing system of the flying saw is designed according to the existing research results.It will include the overall structural design of the sawing system,parameter selection,part design and other contents.The requirement is the ability to process the steel tube with dimension of 300mmx300 mm and wall thickness of 6-10 mm.The Solid Works software is used to model the parts and complete the assembly.Power optimization design of the sawing system of flying saw based on ADAMS In the sawing process of square tube,when the cutting reaches the corner of the steel tube,there will be an empty stroke,which will produce a great fluctuation in the power.This section will minimize the power fluctuation of the empty stroke by optimizing the path of the tool.The idea is to import the model that has been completed in Solid Works into Adams,adding motion pairs,motors,etc.The motion simulation is realized by a series of functions.The kinematics analysis,dynamic analysis and optimization design are carried out based on this.Finally,the power fluctuation coefficient of the flying saw is reduced by 32.46%.Finite element analysis,optimization design and reliability analysis of the key parts of flying saw based on ANSYS This section is to check the key parts of the sawing system of flying saw.Its content mainly includes the use of ANSYS to model the loading and measure its maximum equivalent stress.By performing optimum design on the key parts the weight of the gearbox shell is reduced by 41.27%.The reliability analysis of key parts is performed to verify the safety of the parts at work.The modal analysis is used to measure the resonance of the part at different frequencies.
