Abstract

The invention provides a jaw clamping hydraulic system of a forging manipulator. A three-position four-way directional valve is connected with an oil supply port, an oil return port, a clamping oil cylinder opening cavity and a clamping oil cylinder clamping cavity. An overflow valve is connected with the clamping oil cylinder opening cavity, the oil return port and the clamping oil cylinder clamping cavity. A proportional overflow valve and a signal input port of a clamping pressure signal setting machine are connected with an amplifier. The clamping oil cylinder clamping cavity is connected with an energy accumulator through a one-way throttle valve and connected with the pressure maintaining oil supply port through the directional valve. The directional valve is connected with the pressure maintaining oil supply port, the oil return port and the clamping oil cylinder clamping cavity. Clamping pressure is controlled through the proportional overflow valve, pressure maintaining oil is supplied to a clamping oil cylinder in the clamping process, and therefore it is guaranteed that clamping is stable and reliable, and the jaw clamping hydraulic system has the advantages of being easy to control, high in reliability, and suitable for application occasions high in power and flow and variable in load.

Description

technical field [0001] The invention relates to the technical field of free forging equipment, in particular to a jaw clamping hydraulic system of a forging manipulator. Background technique [0002] The forging manipulator has the characteristics of heavy load, precision, high speed, intelligence, and flexibility. Coordinating with the free forging hydraulic press can greatly improve production capacity, product accuracy, production efficiency and material utilization, and reduce energy consumption. The actions that the forging manipulator needs to complete include clamping and releasing the jaws, forward and reverse rotation of the clamp rod, lifting and tilting, side shifting and side swinging, and the forward and backward movement of the cart. The most important thing to complete the above actions is to complete the stable clamping of the forging. [0003] When the forging manipulator of the prior art clamps the forging, the clamping force cannot be adjusted convenientl...
