Research And Development Of Automatic Pipe Cutting Machine For Oil Storage Cylinder And Working Cylinder Of Shock Absorber

The oil storage cylinder and working cylinder tube parts of the shock absorber require precision machining, incision of good quality, the smooth surface and the low rough degree, flying without edges, burrs, and does not need the secondary processing, it require that the verticality of processing and the end surface of the workpiece is high. But working cylinder parts production efficiency is low in the current domestic shock absorber manufacturing factory of oil cylinder processing process in the cutting tube machine due to the use of simple clamping and processing methods, the problem of skew of pipe material cutting end, there will be the bump scratch, folder compression deformation of the surface of parts caused by working diameter cylinder surface quality within the convex defect, it result that pipe is not a straight line through the gauge inspection. Therefore, in order to solve the above problems, research and development of the full automatic cutter rotary cutting machine of the oil storage cylinder and working cylinder of the shock absorber is carried on.First of all, various types of pipe cutting machine domestic and abroad were investigated and studied in this paper. The working principle and mechanical structure were studied and analyzed, and the advantages and problems of various types of pipe cutting machines were also analyzed. In order to solve the problem of the machining requirements of shock absorber parts and the defects existing in the past pipe cutting machine, the overall scheme design of the pipe cutting machine is completed.Secondly, the structure design of the cutting part of the pipe cutting machine is carried out, a series of calculation of selection, design and checking is carried on, including the calculation of rotary shear, motor selection and calculation, shaft calculation. The structure of feeding transmission parts are design; The three-dimensional modeling of the tube cutting machine is completed by using SolidWorks, and the motion simulation is carried out to verify that there is no interference phenomenon and the structure design is reasonable; The cutting part of pipe cutting machine is analyzed using the software Adams, the contact force between the feed drive components are analyzed, the the stress of the body of tool is analyzed, and the dangerous point of maximum stress does not exceed the allowable value, it meet the strength requirements; The control system design of the pipe cutting machine is carried out, it include the pressure system, the hydraulic system and the electrical system.Finally, the prototype production and prototype running test of the pipe cutting machine verify that the prototype can fulfill the design requirements of the various functions, and the measuring and recording of the prototype scene verify that the prototype can meet demands of productivity and size parameters.
