FIELD: metal processing.
SUBSTANCE: invention relates to the processing of metals by pressure and is intended for the production of trimetallic bar and wire products by drawing. The method includes the preliminary formation of a gripper with pointed conical sections on the product and subsequent drawing of a monolithic draw plate through a conical channel. The maximum extract is determined from the condition of preserving the strength of the component layers of the workpiece, taking into account the technological features of the production of a trimetallic workpiece, the strength characteristics of each of the layers and the relative area of each of the layers that make up the trimetallic workpiece.
EFFECT: invention improves quality of the stretched trimetallic products.
