[CN 201620510767.3] Fine blanking hydraulic press


[CN 201620510767.3] Title of a fine-blanking hydraulic press: Application number of a fine-blanking hydraulic press: CN 201620510767.3 Applicant: Huzhou Machine Tool Factory Co., Ltd. Application Date: 2016-5-30 Patent Type: Utility Model The utility model discloses a fine-blanking hydraulic press, which belongs to the technical field of hydraulic presses and solves the technical problem that the fine-blanking hydraulic press cannot detect waste materials in the prior art, it includes an upper beam, a main slider located below the upper beam, a hydraulic cylinder for driving the main slider to move, and a hydraulic control system connected with the hydraulic cylinder through an oil circuit. The upper beam is equipped with an upper stamping die, and the main The slider is equipped with a lower stamping die. The hydraulic control system includes a controller, a pressure sensor and a displacement sensor. The pressure sensor is used to detect the oil pressure of the oil circuit connected with the hydraulic cylinder, and the displacement sensor, the controller performs waste detection according to the detection signals fed back by the pressure sensor and the displacement sensor.
