Title:
WORK TRANSFER APPARATUS AND PRESS MACHINE
Document Type and Number:
WIPO Patent Application WO/2006/088125
Kind Code:
A1
Abstract:
A fixing side connecting section (151) is formed on an end section of a fixed bar (141), and a shifting side connecting section (152) is formed on an end section of a shifting bar (142). An air clamp (16) is stored inside the fixed bar (141). When the shifting side connecting section (152) is placed over an upper section of the fixing side connecting section (151) and the air clamp (16) is driven by air pressure, a clamping member (165) protrudes from a case (161), turns downward and sandwiches the shifting side connecting section (152) with the fixing side connecting section (151). Since the clamping member (165) is driven by air pressure, a die replacing time can be shortened. Furthermore, since the air clamp (16) is stored inside the fixed bar (141), a transfer feeder (41) can be reduced in sizes.
