Abstract：

The friction piece in the armored vehicle integrated transmission device is a very complex disc-typed part. The conventional processing scheme is of long machining process route, high production cost and low producing efficiency. In order to improve producing efficiency and reduce the cost, in the trial production process of friction pieces for armored vehicle integrated transmission device, the methods of fine blanking process and special die determined treatment were adopted, thereby the process route of parts was shortened as seven from the traditional fifteen working procedures, which reduced production cost and improved producing efficiency and quality. At the same time, the beneficial explorations were made for the feasibility of spring steel fine blanking technology, and high precision friction pieces were applied well in batch production.
