In these years, lead servo press into industry has been a choice, improve material formability and reduce stamping time has been an important goal. This paper divided into two parts. First, using different kind of servo stamping motion curves, including crank and vibrational curve, to find out formability about SUS304 and A6061. According to the result, SUS304 by using vibrational curve has 67% more formability than using crank curve. Under the same forming depth, thinning rate reduce 14%. In addition, by using vibration curve, A6061 increase 0.09% forming depth than using crank curve, and in the same forming depth, thinning rate reduce 4%. Second, to shorten the forming time and reduce the thinning rate, we optimize the single target of SUS304. We used finite element software (Qform) and meshing software (Gmesh) to simulate servo press and set different kind of Deep drawing parameter. We also use SEYI servo punch to do experiments and comparing experiment result and simulation result. At last, we used Taguchi Method to find out the best forming parameter. According to the experiment, the optimize parameter of shorten forming time has reduced 0.156 sec than L9 shortest forming time, the optimize parameter of thinning rate has reduced 0.833% than L9 lowest thinning rate. |
