Abstract


To improve the performance of parts used, lightening the weight of components, material saving is the goal and the development trend of the modern advanced manufacturing technology to pursue, in the automobile industry, aerospace and other fields is particularly urgent pursuit. Advanced manufacturing technology of tube hydroforming technology as a hollow characterized by lightweight and integrity of variable cross-section of light components, people pay more and more attention. Because the domestic this technology started relatively late, the market is unable to find related equipment, hydraulic this topic transforms the bulging test bench is the experimental platform for just over a year ago design and production, in the practice of nearly half, the tube forming effect is not ideal, found that there are many deficiencies in design of the test bench system of the internal high pressure forming, brings a lot of inconvenience to experiment. Its functions are introduced in detail in this paper tube hydro forming system contains the complete. Each part of a detailed analysis on the effect of tube forming, and also lists the selection criteria of key design parameters and the parameters of tube hydroforming. In this paper the test bench forming experimental problems, given the detailed introduction and analysis, to find the causes of the problems, and points out the shortcomings of the original system design and retrofit scheme for the experimental platform and the transformation of a specific design process. Aiming at the defects forming test-bed of forming pipe axial feeding force is not controlled, based on the original test table of the optimization design of the hydraulic system, design of the axially adjusted the feeding capacity of internal high pressure forming test-bed system, and through the host computer and LabVIEW virtual instrument technology optimizes the design test bench. And on the axis side to promote the hydraulic cylinder hydraulic control system to carry on the simulation analysis of mathematical modeling and stability, and enumerates some programming design based on PLC and labview.
