Abstract
The utility model relates to a follow-up bi-directional control mechanism for a hydraulic steel bar hoop bending machine. The bi-directional control mechanism comprises a cylinder, a gear shaft, a gear rack, a hydraulic control valve, a bi-directional control valve, a stroke switch valve and a stop. The bi-directional control valve is arranged on the polished surface of the gear rack, moves along with the gear rack and then touches a bent hoop limit stop; the bi-directional control valve acts to control an oil path to release pressure; the hydraulic control valve controls the cylinder of a main oil path to retract; a piston rod of the cylinder drives the gear rack to pump back; the bi-directional control valve interlocks to retract to the bottom of the cylinder and touch the stroke switch; and the stroke switch controls the main oil path to release pressure. The follow-up bi-directional control mechanism is capable of improving the reliability of the hydraulic steel bar hoop bending machine, greatly lowering the manufacturing cost and the maintenance cost and improving the operability and the hoop bending precision of the hydraulic steel bar hoop bending machine.
