The welded structure of the symmetrical three-roll bending machine includes a frame, a base and other constituent steel structural members.
Welding structure of symmetrical three-roller bending machine Process: sheet entering factory inspection - sheet pretreatment - blanking - bevel processing - welding - weld inspection - annealing treatment - roughing - vibration aging - finishing - surface removal Rust, anti-corrosion - top coat.
The selected material for the welded structural parts of the symmetrical three-roller bending machine is Q235. The thickness of each structural plate is determined by calculation to meet the requirements of strength, rigidity, stability and long-term safe use, and meets the relevant requirements of the national standard for coiling machines and steel structures. .
The welded joint of the steel structure of the symmetrical three-roller bending machine must be visually inspected. The surface of the weld should be uniform, beautiful, and smooth with the base material, and there should be no defects such as cracks, weld fusion, and porosity.
The necessary welded joints of the steel structure of the symmetrical three-roller bending machine must be welded through the groove, and the height of the welding feet is not lower than the thickness of the thinner of the two-phase welded parts.
After the steel structural parts of the symmetrical three-roller bending machine are welded, stress relief treatment must be performed before machining.
