Numerical Simulation And Experiment Research On Low-Energy Consumption Blank Holding System

Presently, the hydraulic technology has all made the significant progress in the realization of high pressure, high speed, high efficiency, low noise, redundant reliability, high integration and so on, also has many new achievements on consummating the proportional control, the servo control, the numerical control technology as well as electro-hydraulic integration. Along with the progress of science and technology as well as in order to adapt the operation requirements of hydraulic press and strengthens itself competitive ability, the high efficiency, low-energy consumption, high controlled performance and so on are becoming the main development trend of the hydraulic technology.The principle of the low-energy consumption blank holding now closely accords with the hydraulic development trend and complied with the energy conservation tendency for the hydraulic press designs. After investigating some related material about domestic and oversease energy conservation, proposes the plan that take the energy recycling as the main realization question on sheet drawing forming press. The main purpose of this research topic is how to make the fluid pressure energy acquitted by the blank holding cylinder change into the work energy of the main gliding block under the servo-control. So that to achieve the goal of saving energy.This paper firstly presents the expressions of energy consumption in two types of blank holding, the conventional hydraulic cushion and cushion-compensating cylinder, in single-action deep-drawing hydraulic press, and shows through comparison that the consumption in later is far less than in the former.Using MATLAB/SIMULINK to mode and simulate the two kind of simplification model of the micro-energy consumption, the result indicates that the system rapidity, stability are extremely ideal and has very good applicationprospect.Finally, develops the LabVIEW control procedure and using the equipments that the laboratory already have to compose the micro-energy consumption blank holding test system. By comparing the experimental data and the simulation data, we know the stability of the system conform to the design requirement.
