The apparatus (1) comprises independently operable support members (2), each having separable tool halves (3) defining an opening (4) configured to receive a pre-heated rectangular beam (5). Each tool half has an axially adjustable shaft (6) movable along channels (9) disposed in opposite sides of rectangular frames (7), which are rotatably mounted in cylindrical housings (8). The cylindrical housings may be fixed in any desired position on the beam, and the frames may be locked or rotated within the housings in response to manual, electrical, pneumatic or hydraulic actuation which may be remotely operated, pref. by a programmable control unit. On completion of the process the beam may be quenched by water or gas. Alternative embodiments are disclosed for handling circular beams. |
