Set Up

On the basses of analyzing the defects of variable blank holder force hydraulic press on construction and its rigid being not enough,the realization of designing method,working principle,hydraulic and system for ne controlling w type upper multi-point deep drawing with variable blank—holding force controlled by computer was introduced.In order to verify the effect of application of this set up,the testing results of deep drawing a rectangular box and a cylindrical cup formed component was presented. The results show that the equipment has low cost, general in using and optimal efficient of controlling.
