The Study On The Stability Of Traction Precision To The Wire Products

With the global economic recovery, industry of our country has been rapid development, manufacturing of metal wire demand continues to rise, and the overall performance of China’s production of metal wire drawing machine production line is relatively backward, especially drawing forming the main equipment of traction machine stability differential, traction machine work bearing parts of the main drum and the frame, the advantages and disadvantages of the mechanical properties is the traction machine stability is important reflect. At present domestic for wire drawing traction machine frame and the drum of theories, this paper tries to LZ8/600 straight into type wire drawing machine frame and a reel of traction, and effectively improve the traction machine for wire drawing product accuracy and stability of the, this paper mainly research in the following aspects:(1) Through reading and analysis of the status quo of the similar products at home and abroad, in order to improve the precision of stability of traction machine as the starting point, determine the content of this article.(2) Combined with the characteristics of the operation of wire drawing machine, drawing machine traction is proposed stability requirements associated with the design parameters, and the drawing force and load torque of a detailed calculation and checking, in determining the overall layout of the drawing machine, drawing machine working principle is expounded, finally completed the assembly drawing machine virtual prototype engineering drawing in software UG.(3) The failure forms and causes of the drum are introduced, and then the calculation and analysis of the mechanical model of the drum, reveals the cylindrical box parts under compressive deformation mechanism under stress, A formula to calculate the stress of cartridge compression, as the basis of finite element analysis and optimization of the drum cartridge design in theory laid a good.(4) The analysis of drawing the tractor traction drum and the frame of the finite element simulation analysis and buckling stability by finite element software ANSYS Workbench and Hyper Mesh software, the stability of the frame is put forward the improvement scheme, and provide an important basis for the structure optimization of drum.(5) In the premise of ensuring the accuracy and stability of the traction drum work, the structure optimization of the drum, finally get the optimal solution of the theory on the drum, drum weight 15.3%, the surface stress was reduced by 18.9%; in order to verify the feasibility of the optimization results, on the basis of the design of variable size optimization. Has carried on the analysis from the new assignment modeling, Simulation analysis. The critical buckling load is increased by 18.8%(6) The wire drawing traction precision stability test was optimized and Improved traction machine idling test, break detection, surface quality inspection.
