[CN 201710389510.6] Hydraulic fast forging machine
[CN 201710389510.6] Title of Hydraulic Fast Forging Machine: Application Number of Hydraulic Fast Forging Machine: CN 201710389510.6 Applicant: Jiangsu Desheng New Material Forging Co., Ltd. Application Date: 2017-5-27 Patent Type: Application for Invention The present invention discloses a hydraulic fast forging machine, including an oil cylinder connected with a hydraulic rotary valve and a fixedly arranged displacement sensor; Through the rotation of the valve core, the direction of liquid flow is changed and interrupted, the piston rod in the cylinder connected to the valve body completes a downward pressure and upward movement when the valve core rotates once. The precision of forging size can be automatically controlled through the rotary valve in the forging machine and the displacement sensor. The invention has simple structure, convenient operation and high degree of automation. Through the setting of the proximity switch, the valve core can be stopped from rotating at the corresponding position to complete the required operation; after the rotary valve of the invention is connected with the oil cylinder, it can replace the air hammer and realize short The stroke is fast forging, with low vibration, low noise and high cost performance.
