Document Type and Number:
WIPO Patent Application WO/2019/058797
Kind Code:
A1
Abstract:
A press device (1) is provided with a press device main body (90), which has a slide (2), a bolster (3), a servo motor (21), an electrical storage panel (42), a discharge unit (11), and a contactor (13), and a main breaker (9). The servo motor (21) drives the slide (2). The electrical storage panel (42) can supply stored electric power to the servo motor (21). The discharge unit (11) discharges an electric charge stored in the electric storage panel (42). The contactor (13) interrupts the electrical connection between the electrical storage panel (42) and the discharge unit (11) in an electrified state and electrically connects the electrical storage panel (42) and the discharge unit (11) in a non-electrified state. The main breaker (9) supplies or stops the electric power from a plant power supply (100) to the press device main body (90). Electric power for electrification is supplied from the plant power supply (100) to the contactor (13) without passing through the main breaker (9).
