| description | PROBLEM TO BE SOLVED: To provide a hydraulic device capable of acquiring extremely high position accuracy of an actuator with a simple and cheap configuration, and a press machine capable of acquiring a molding with extremely high dimension accuracy.SOLUTION: A hydraulic device includes: a hydraulic pump (40); a motor (50) for driving the hydraulic pump (40); an actuator (20) to which oil is supplied from the hydraulic pump (40); a position sensor (21) for detecting a position of the actuator (20); a pressure sensor (42) for detecting a pressure of the oil; and a controller (60). The controller (60) controls the pressure of the oil supplied to the actuator (20) with a detection pressure of the pressure sensor (42) when the actuator (20) reaches a target position being a target pressure, by receiving output of the position sensor (21).
【課題】簡単安価な構成で、アクチュエータの極めて高い位置精度が得られる油圧装置、および、極めて高い寸法精度の成形品が得られるプレス機を提供すること。【解決手段】油圧装置は、油圧ポンプ（４０）と、上記油圧ポンプ（４０）を駆動するモ−タ（５０）と、上記油圧ポンプ（５０）から油が供給されるアクチュエータ（２０）と、上記アクチュエータ（２０）の位置を検出する位置センサ（２１）と、上記油の圧力を検出する圧力センサ（４２）と、コントローラ（６０）とを備える。上記コントローラ（６０）は、上記位置センサ（２１）の出力を受けて、上記アクチュエータ（２０）が目標位置に達したときの上記圧力センサ（４２）の検出圧力を目標圧力として上記アクチュエータ（２０）に供給する油の圧力を制御する。【選択図】図１ |
