DIE-STAMPING TOOL Russian patent published in 1994 - IPC

FIELD: die-stamping operations. SUBSTANCE: tool has two halves with working hollows. At inlet end working hollow is beveled. At least one half of tool has projections displaced relative to one another and mounted for rotation in bearings. On one side bearings are capable of forward movement opposite to surfaces of engagement, and bearings on another side - in the direction from inlet end to outlet end. Application of stamping effort leads to bearings reciprocating movement in their directions, and projections after turn-through inside them incline working hollow to make deformation with subsequent involving in contact of the whole surface of working hollow. EFFECT: enhanced handling convenience. 1 dwg
