Three-roller full hydraulic drive: Each independent drive roller is directly connected with a hydraulic motor, and the torque can directly drive the plate to avoid power loss. Through the proportional control valve and the digital electric control system, the steel plate rolling speed can be steplessly adjusted.
The depressing cylinder is built into the bed. It solves the problem of piston rod strain caused by the accumulation of oxide scale on the workpiece during the rolling process caused by the exposed piston rod of the lower pressure cylinder; realizes that the upper pressure lower cylinder and the lower pressure cylinder both work with rodless chambers. The number of high-pressure sealing rings is reduced, and the reliability of the depressing oil cylinder is improved.
A cone small mouth reduction device is provided on the side of the open and close bearing seat of the upper and lower work rolls. The electronic control system of sheet metal stamping press machine sets the upper working roll to incline two and maintains the relative balance of the upper roll, which can realize the rolling of small diameter and large cone angle that cannot be achieved on other machines on this three roll bending machine.
Through the unique hydraulic system design and working pressure detection, combined with the electronic control system design, the three roll bending machine can be smoothly unloaded under high pressure, avoiding the bouncing movement of the workpiece and the "water hammer" generated by the hydraulic system The impact of the phenomenon on the pipeline.
The hydraulic system and the working pressure of each cylinder, the working state of the motor, and the displacement of the displacement sensor are displayed on the display in the form of instrument controls. The display content also includes the power failure status of each hydraulic valve, each soft and hard limit prompt, equipment overload alarm, oil temperature alarm, and cooling promptly.
