(GW50A automatic bending machine, GW42D automatic bending machine, GW42E automatic bending machine) works

GW50A automatic bending machine introduced by him is driven by a hydraulic, PLC control frequency heating hydraulic pipe bender works: also GW50A GW42E automatic bending machine and automatic bending machine were analyzed on aspects of the hydraulic system and PLC control systems were introduced, and described the aircraft's performance characteristics .GW42D automatic bending machine control system that uses a programmable logic controller and human-machine interface, improved system reliability and its flexibility, enhanced anti-jamming capability of automatic bender.
