Cam fine blanking technology and die design

The fine blanking technology of cam were analyzed, its blank layout was designed, the fine blanking force was calculated and stamping equipment selected, the fine blanking die clearance and rounded edge were determined. The fine blanking compound die structure were designed, the materials and heat treatment specifications of fine blanking mold work parts were selected and the gear plate structure designed. Practice shows that the process program used was reasonable, mold design proper and equipment selection reliable. By adopting fine blanking technology, not only improve product quality, but also significantly reduce the mechanical processing time. Thus the product cost would be lowered and the production efficiency increased. Fine blanking technology will have broad application prospects. (C) 2011 Published by Elsevier Ltd.
