[CN 201611176586.2] Active anti-deflection electro-hydraulic control system for sliding block of rotary forging hydraulic press
[CN 201611176586.2] Title of active anti-deflection electro-hydraulic control system for sliding block of rotary forging hydraulic machine: application number of active anti-deflection electro-hydraulic control system for sliding block of rotary forging hydraulic machine: CN 201611176586.2 applicant: Nantong forging equipment co., ltd. application date: 2016-12-19 patent type: invention application the present invention relates to an active anti-deflection electro-hydraulic control system for sliding block of rotary forging hydraulic machine, including left front and right rear two-way ball valves B, right servo hydraulic cylinder, right valves, right middle servo hydraulic cylinder, right middle servo valve, left rear right front two-way ball valve B, right front servo hydraulic cylinder, right front servo valve, constant pressure oil source, left front right rear two-way ball valve A, left front servo hydraulic cylinder, left front servo hydraulic cylinder, left middle servo valve, left rear servo hydraulic cylinder, left rear servo hydraulic cylinder, left rear right front two-way ball valve A, middle two-way ball valve A. The advantage is that it can accurately control the horizontal posture of the slider in the working process of the rotary forging hydraulic press, actively correct the offset and torsion of the slider, ensure the positioning accuracy of the rotary forging punch and the lower die, improve the force of the slider guide rail, and improve the processing accuracy of the rotary forging hydraulic press. It has the characteristics of high degree of automation, high control accuracy, strong anti-bias rigidity, fast response speed and high integration.
