Design And Research On Sealed Band Pneumatic Headband

With the proposal of emerging development strategies such as the “Belt and Road”initiative,the demand for infrastructure resources led by the steel industry has been stimulated,providing huge space for the development of the steel baler packaging market.The binding head is the core component of the steel baler.The optimization of the structural design of the binding head,static analysis and dynamic simulation have important R&D value for the improvement of the intelligence level.Based on the needs of the domestic iron and steel enterprises for the banding technology of steel strips,the paper is writen to research and develop a sealed buckled pneumatic stripping head.A new type of strapping head with a high degree of automation has been developed through the study of the scheme of the strip steel head structure,statics analysis,dynamic motion simulation and control program design.Among them,the occlusion mechanism,as the core component of the strip steel binding head,directly affects the strapping quality of the strip,which is the focus of this study.(1)The design data of the binding heads was collected and organized online,use SolidWorks to establish a three-dimensional model of the strip binding head,simulate the binding head binding motion process,and analyze its working principle.According to its structural composition,the composition of the main parts of the binding head is studied,evaluated and corrected to determine the final overall design of the binding head.(2)The working principle and operation flow was explained of the strapping head of the steel strip,and analyze the key parts of the bite mechanism.Based on the ANSYS Workbench finite element software,static analysis is performed on the key components of the established occlusion mechanism.The maximum position of the equivalent stress and strain at the key position of the occlusion mechanism is found and the safety performance of the occlusion mechanism is evaluated.(3)Process analysis is performed on the key parts of the occlusion mechanism.AutoCAD drawing software was used to simulate the trajectory of the key parts of the occlusion mechanism,and the geometric dimensions of the key parts of the occlusion mechanism were mapped.At the same time,based on ADMAS kinematics analysis,the control variable method is used to simulate and analyze the influence of the clearance between the shaft holes of the key parts of the occlusion mechanism on the position of the knife edge of the eroding blade,and the evaluation is optimized.(4)Based on the Siemens S7-200 design of the strapping head pneumatic PLC control system,the corresponding control program is designed for the biting head biting action flow.After the test is conducted,the PLC overall control procedure is determined.Based on SolidWorks three-dimensional modeling,ANSYS Workbench finite element analysis,AutoCAD two-dimensional drawing,and ADAMS kinematics simulation technology,three-dimensional modeling of strapping heads,static analysis,process design of the bite mechanism,and impact crushing are successively performed.The analysis of the biting motion of the blade tip position can effectively improve the biting accuracy of the binding head structure design.Experiments show that the above design scheme and technical application are fully applicable to practical work.At the same time,based on the S7-1500 PLC platform designed modular control system for strip heads,it is simple,convenient and easy to tie the head to control the flow of the strapping process.This has important reference value and practical significance for the optimization of the structural design of the steel strapping head and the improvement of the occlusion accuracy in the future.
