| Abstract: | Main technological forming parameters, rapid adjusting principle and characteristics of 200 kN rapid adjusting multi-point forming (MPF) press for sheet metal were introduced. Influences of adjusting forming precision on forming parts were analyzed in detail. Theoretical error, and the reasons were stated from several aspects. Adjusting displacement error, in compare with aim displacement that the element move to displacement of five elements in multi-point forming press was tested, all testing results was in the range of designing precision, and met the demand of multi-point forming press. |
