Sažetak
The paper is concerned with the influence of choice of machine with optimal characteristics, and influence of heating metal sheets on the effects of energy management and environment protection. Numerical method of spring-back determination after plate bending was used. Same is shown on diagrams, for different materials. Bending force and calibration force in plate bending are also elaborated. For numeric procedure the finite element method is used. Calibration force is determined when bending force and calibration coefficient are known. Significant factors for determination of bending force are: the material of the circular plate, bending radius of the circular plate, diameter of the circular plate, thickness of the circular plate and method of loading of the circular plate. The calibration coefficient is determined by experiment. The analysis of bending plate is limited to the facts and figures used so far in the fabrication of spherical tanks, i.e. for deformations up to 1 %. The factors that have the most significant influence on the amount of mechanical spring-back are: calibration forces, plate material, punch radius, punch motion, plate thickness and plate diameter. In order to research the influence of punch radius Rk, plate thickness and plate diameter, according to technological and productivity conditions experiment factor plan was used. The industrial experiments with scale dimension 1:1 were performed. Experiments were conducted using randomized distribution in attempt to avoid systematic errors. The considered factors were: punch radius 4500 and 4925 mm, plate thickness 16 and 29 mm, plate diameter 1800 and 2000 mm. Using all above mentioned considerations, on the basis of experimental and industrial researching, the law for coefficient of mechanical spring-back of calibrated plate with constant plate diameter KII can be derived.
