Casting element for e.g. hammering press, has workpiece contact surface defining first side section extending from middle portion in direction opposite to pair of second side sections, where side sections are axially offset to each other

摘要

The element (20) has a body section (21) with a workpiece contact surface (22) that exhibits an axial direction and circumferential direction that is perpendicular to the axial direction. The workpiece contact surface is concavely curved in the circumferential direction. The contact surface defines an axially extending middle portion (23), a pair of first side sections (24) extending from the middle section, a second side section (25) extending from the middle portion in a direction opposite to the first side sections. The side sections are axially offset to each other.
