Analysis Of Dynamic Characteristics Of High Strength Prestressed Steel Wire Spinning And Rolling Reducing Device

The prestressed steel wire,which is made of High quality carbon steel strip,is formed by isothermal quenching and drawing,it is the most commonly used steel strand in China.The object of this study is a high strength prestressed steel wire with diameter of 10.5mm and yield strength of 1300 MPa,belonging to the slender shaft parts.There are two common methods for machining the outer end face of slender shaft parts,that is,roll forging and cutting.The roll forging method has low efficiency and large noise.The cutting creates tensile stress on the surface of steel wire.For the above problems,this paper has done the following contents:This paper described the finite element theory of high strength prestressed steel wire in the Necking Process.The ANSYS/LS-DYNA software was used to simulate the process of the diameter reduction of steel wire,and the force and energy parameters were determined.IT laid the foundation for the later structural design of the device.According to the design concept of the existing spinning machine and roller mills,the overall layout of the device is determined,the assembly of the three-dimensional model of the device is completed on Solidworks platform.The force analysis of diameter reduction system of the device is carried out,and the contact?forcecontact force direction angle at each contact point were obtained.The dynamic analysis and virtual prototype simulation analysis of Diameter reduction system of the device are carried out,and the inherent characteristics of the device are analyzed from two aspects of theory and simulation,verified the accuracy and rationality of the design.
