Abstract：

In order to increase economic efficiency for head cover, two kinds of progressive dies were designed for stamping production, and an automatic feeding installation transmitting slices of semifinished products between the two dies was conducted. Owing to doublerow layout without carrier, the material utilization ratio was increased to 60%, product cost was effectively reduced and productivity was improved. A slice was carried to reclaimed area of drawing die by long range slipway cylinder after the slice was split reliably from a stack of slices by the pushed slice mechanism with spring in the automatic feeding installation, and the slice was suspended on the positioning conical surface by ascending cylinder from the reclaimed area to take accurately and feed accurately into drawing die by a reclaimer. The automatic feeding installation was coordinated controlled with punch press and a synchronous signal of cam by PLC. The results show that the installation can ensure the double slices feeding precision and stability with ingenious mechanical structure, low cost, high efficiency and automated production.
