Abstract：

In design of punching die in crankshaft shell, because of its special shape and production process, there are difficulties in positioning for crankshaft shell and core rod female dieUsing the float positioning mechanism ,the crankshaft shell could be well fixed to the position in the dieUsing cylinder aided inclined wedge and inclined slide block mechanism,core rod female die could be fixed to the position and repositioned well in the dieUsing compounding punch, the rising of blank could be avoided. Big blanking gap is used in the dieThere is a good effect in manufacture
