Analysis on stamping forming process of forklift body covering parts and design of springback compensation
In order to solve the excess springback problem of forklift body covering part after stamping and forming,the numerical simulation of the stamping process of forklift fender was car-ried out by using finite element software.The actual stamping results of several fenders were mea-sured and collected,and the numerical simulation and the actual results were basically in agree-ment.Various factors affecting springback were analyzed,especially the influence of die structure parameters.Orthogonal experimental design method was adopted to design a multi-factor and multi-level orthogonal experimental table of die structure parameters,and finite element numeri-cal simulation experiments were carried out.The die structure that met the requirements for stamping and forming was determined,and the fender parts were once stamped and formed with-out the repair.
