Research On Springback Iteration Compensation Technology For Shaft Parts Based On Deflection Control

In recent years,with the development of China-made 2025,China has achieved rapid development in the machinery manufacturing and automotive industries.With the continuous increase in the scale and technological level of these industries,the quality and accuracy of some key components have become increasingly stringent.Shaft parts,which are important components of mechanical equipment and automobile equipment,will undergo bending deformation during the long-term use,which will affect the efficiency of the equipment or the safety performance of the equipment.For some equipment devices,bending axes with specific deflections are used,and it is difficult to achieve the required precision in production.In addition,there are various kinds of shaft parts and the materials are different from each other.There is a problem of springback when shaft parts are straightened or bent.It is difficult to find a universally applicable process method for straightening or bending a shaft part in a project.For these problems of the shaft parts,this paper uses a three-point straightening model as the basis,combining with the iterative idea of following the unknown function in "Numerical Analysis",to establishment of an iterative compensation method for springback of shaft parts based on deflection control,And verify the feasibility of this method from the perspectives of theory,simulation and experiment.According to the three-point bending experiment of the 45 th steel straight axis,the results are combined with the "interpolation method" and "interpolation method" in "numerical analysis" to establish and prove the iterative compensation theory for bending and straightening springback of shaft parts.Deflection is used as the reference for rebound compensation,and the correctness and feasibility of this method is proved by the theoretical formula.Finite Element Model of Axle Parts Bending and Straightening Using ABAQUS Finite Element Simulation Software.Select two materials for the simulated part and the corresponding target deflection.The iterative bending and straightening process of the simulated axis was performed according to the principle of the interpolation and chord-clamping method respectively.To verify the correctness of the two rebound iteration theories.By summarizing finite element simulation data,selecting two kinds of shaft parts.Using two kinds of rebound iteration theory to flex and straighten them on an intelligent leveler To further verify the correctness of the theory and the feasibility of the project.
