System Design Of Steel Pipe Automatic Butt Tool And Research On Performance

Steel Pipe Automatic Butt Tool is special equipment which is based on the projectof"research on marine engineering and efficient pipe production line" that is derived fromOffshore Oil Corporation. The aim of this project is to develop a set of pipe production linewith Steel Pipe Automatic Butt Tool, which is with independent intellectual property rightsand the international level. It will replace manual butt process, reduce the difficulty of theprocess, and improve production efficiency and the quality of the butt process.Steel Pipe Automatic Butt Tool is a machine for φ406mm~φ914mmsteel pipes,toachieve self-aligning feature, and a variable nozzle for the wrong test, adjust the weldlocation, warm, straightness detection capabilities of special equipment.Based on the domestic and foreign production of pipe welding research, butt ofincoming workpiece parameters, butt parameters and reference to the finished workpiecefunctional requirements etc., the paper presented of Steel Pipe Automatic Butt Tool ’soverall program and structural design, detailed design of Steel Pipe Automatic Butt Toolmechanical systems, while analysis the hydraulic system, control system andworkflow.According to the overall program of Automatic Butt Tool mechanical structure,detailed design and calculations the mechanical transmission part, determine the size of themain structure. In addition to structural design optimization based on the data, but also forthe purchase-driven components, control components to provide a basis; based on thetheory of error on the Automatic Butt Tool analysis of mechanical systems for accuracy anderror calculation, according to the sources of error, error assessment and error analysis ofthe basic principles of treatment, combined with the Automatic Butt Tool functionalrequirements of the machine, the length of the gantry measuring institutions andorganizations analyzed and calculated to determine Automatic Butt Tool mechanical systemmeet the design requirements.Analysis of the Steel Pipe Automatic Butt Tool in the keytechnology of the butt process.Mainly for dimensional accuracy of steel nozzle groupanalysis of the impact calculations, obtained the range of steel pipe the Automatic Butt Toolcan butt, and determine the location of the weld, it affected the quality of finished steelafter welding parameters,ensure the quality of postweld pipe. Automatic Butt Tool is inoperation on the position requires accurate, precise location of the preparation group for the control workflow; Based on the working principle of the Steel Pipe Automatic Butt Tooland design requirements, test the experiments performance of engineering prototype.Presented variety of corresponding test methods of the performance, and analysis ofexperimental results; also explain the problems and improved method of Steel PipeAutomatic Butt Tool design process.
