JPS54132453A - Handling device for upset forging for long size steel pipe - Google Patents

Abstract

PURPOSE: To automate the charge and discharge of long size steel material at the exact position against the upsetter, and to greatly improve the working efficiency, by constituting of the elevating bed, the sliding bed, the idle roller group for supporting the material, the charger for charging the material into the forging machine, and the clamp.

CONSTITUTION: The butterfly kicker 42 dips up the pipe 1 and lays it on the idle roller 12 for supporting the material. The pinch roll stands 31, 31, pinch the pipe 1. When the pipe 1 is inserted into the die hole 56 of the upsetter 6, the clamping stands 42, 42, close and pinch the pipe 1. The pipe 1 is thrusted against the die 54, the die 54 closes, and then, the first upset forging is performed. The pipe 1 is detached from the die 54, the elevator 9 is operated, and the bed 10 is brought down to the position for the second upset forging work. The pipe 1 is thrusted against the die 54, the die 55 is closed, and the second upset forging is performed.
