[CN 201821653859.2] power control mechanism of hydraulic forging hammer
[CN 201821653859.2] Title of Hydraulic Forging Hammer Power Control Mechanism: Application Number of Hydraulic Forging Hammer Power Control Mechanism: CN 201821653859.2 Applicant: Jiangsu Zhuhong Forging Co., Ltd. Application Date: 2018-10-11 Patent Type: Utility Model The utility model relates to a hydraulic forging hammer, especially to a hydraulic forging hammer power control mechanism. The frame is provided with a hammer arm and an oil pipe connected with an oil pump. The hammer arm is provided with a hammer head at the bottom of the piston rod, the piston rod and the hammer arm enclose an upper oil cavity and a lower oil cavity. The oil pipe communicates with the upper oil cavity and the lower oil cavity. The frame is provided with a first rotating shaft, and the first rotating shaft is provided with a first connecting rod and a second connecting rod. The oil pipe is provided with an oil inlet and an oil return port, and the oil inlet is plugged with a first plug. The utility model has the effect of conveniently adjusting the striking speed. By rotating the first rotating shaft, the first plug post can change the oil flow rate of the oil inlet, and the second plug post can change the oil flow rate of the oil return port. Since the combination of the hammer arm and the piston rod is equivalent to an oil cylinder, the oil inlet and The change of the oil flow rate at the oil return port will affect the movement of the piston rod, so as to achieve the effect of adjusting the speed of the piston rod's telescopic action, that is adjusted.
