【Abstract】 Aiming at the flaw generated during the forming process. the experiment was made on the forming of the short-wallboard by using the craft method which is connecting the rolling and bending together to manufacture. By means of improving the craft method and fixing the craft parameter, the problem was resolved that the flaw was generated during the forming process. The products have quality and meet the design requirements.更多还原
