【Abstract】 The importance of computer control technique on improving the quality of autobody panel is presented. Also the hot research on the subiect of the blank holder force (BHF) on autopanel stamping in recent years is illustrated. Some key techniques, such as the principle of the influence of BHF upon the formabilty of sheet parts, the requirements of the device of BHF, the state of BHF device at home and abroad and the BHF control curve, are discussed Finally the idea of non uniform BHF used for the autopanel with large size stamping process is put forward, and problems as well as the corresponding solutions are set forth.更多还原
