Abstract
A method for evaluating the blanking edge flanging forming performance of high-strength steel plates. The high-strength steel plates refer to steel plates with a tensile strength of not less than 700 MPa. The high-strength steel plates with blanking edges are used to test the blanking edge flanging forming experiments. Three-dimensional array data of limit parameter values of flanging forming, several discrete three-dimensional array data are fitted to form a space limit surface, according to the space limit surface, whether the design value of high-strength steel plate blanking edge flanging can be realized simply The evaluation is given intuitively, which is conducive to improving the production pass rate of high-strength steel plate blanking and flanging forming products.
Description
technical field [0001] The present invention relates to the evaluation technology of whether the blanking edge of the steel plate can be flanged or not, especially a method for evaluating the forming performance of the blanking edge of the high-strength steel plate. The high-strength steel plate refers to a steel plate with a tensile strength not lower than 700MPa. The high-strength steel plate with blanking edge is obtained through the blanking edge flanging forming experiment test to obtain three-dimensional array data with flanging forming limit parameter values, and several discrete three-dimensional array data are fitted to form a space limit surface, according to the space limit surface Whether the design value of blanking and flanging forming of high-strength steel plate can be realized simply and intuitively can be evaluated, thereby helping to improve the production qualification rate of blanking and flanging forming of high-strength steel plate.
