FIELD: plastic working of metals, namely tools for drawing trihedral shapes.
SUBSTANCE: drawing plate is provided with three hard-alloy precision inserts arranged by inclination angle 120° one relative to other. One insert is stationary; two other inserts are movable. Drawing plate also includes two pairs of power wedges for setting desired cross section of trihedral shape and creating pre-stressed state; two stop screws for taking up gaps after regrinding hard-alloy inserts. Invention provides possibility for creating pre-stressed state of unit, quickly readjusting unit for other size without changing inserts.
EFFECT: possibility for producing high accuracy trihedral shapes, minimum hard alloy consumption for making inserts.
