Work carrying device of pressing machine
Abstract:
A transfer feeder 41 has a lift/clamp device 80 moving a bar 14 in a lift direction and a clamp direction, a plurality of feed carriers 52 installed on the bar 14, and feeding linear motors 53 driving the feed carriers 52 in a feed direction. Since an object driven by the feeding linear motors 53 can be formed small since the feed carriers 52 are installed on the bar 14, the feeding linear motors 53 having a small capacity can be adopted to simplify the structure of a transfer press 1.
