Products: integrated H-beam automatic welding production lines: one type H-beam production line, also known as H-beam automatic welding production lines short process, H-beam welding form is shaped in accordance with the work place, at the same time on both sides of the seam weld two angles, as H steel welding, this method is more advanced and reasonable process, a small variety of H-beam welding residual stress, while improving the welding efficiency. Because of symmetry welding, after welding the web substantially no deformation, the diagonal of H-beam flange deformation after welding hot direct correction, reducing the corrective force, and improve the correction accuracy and thickness. This production line is a complete assembly, welding, orthopedic, hold up, the material and all other processes, with the production process is reasonable, the process is short, fast-paced high-speed production characteristics, is H-shaped steel manufacturers in the purchase of the device of choice. H-beam automatic welding production line is used for welding T, H-type structural steel and special equipment. The main technical features of innovation: 1, H-beam welding production methods are in accordance with the H-shaped steel "work" type place, at the same time on both sides of the seam weld two angles, greatly increasing the welding efficiency. Because of symmetry welding, basic web deformation after welding; 2, orthopedic institution by eccentric press roll angle butt after achieving thermal deformation of H-beam flange direct correction, reducing the corrective force to improve the correction accuracy and thickness; 3, using a set of legislation - Welding - correction in an integrated manner, small footprint, eliminating inter-process flow, improve production efficiency; 4, in the web and flange plate on the way, using each of the two groups before and after the way to improve the positioning accuracy; 5, wire feeder and torch soft connection, welding torch angle can be adjusted; 6, the workpiece walking motor with variable frequency drive, smooth courier, welding quality; 7, using the web under hydraulic pressure, and elevating screw with the realization of variable cross-section beam welding. The main technical parameters: 1, H-beam height: 200 ~ 2000mm; 2, H-beam length: 6000 ~ 15000mm; 3, the web thickness: 6 ~ 40mm; 4, flange width: 200 ~ 800mm; 5, the flange thickness: 6 ~ 40mm; 6, courier range: 400 ~ 1000mm / min; 7, the effective working length: 15000mm; 8, the total power: 150KW (including two DC1000 welder); 9, welding position: horizontal angle joints; 10, welding way: double-sided automatic submerged arc welding; 11, welding power source: single wire submerged arc welding, bilateral 1000A; 12, Speed ??mode: AC frequency; 13, program control: PLC; 14, torch angle: 30 ° - 60 ° can fine-tuning. Production line configuration structural features: 1, the group established institutions: the motor, reducer, chain, sprocket drive transmission roller to achieve the transfer of the workpiece welding to achieve the flange and web of automatic positioning linkage mechanism driven by a hydraulic cylinder, enabling assemblage welding workpiece; 2, welding mechanism: the motor, reducer, chain, sprocket drive transmission roller, to achieve workpiece traction. By hydraulic rod and screw vice clamp the workpiece to ensure correct positioning of the position of the workpiece. Torch cylinder into the feed mechanism by welding positions, two welders welding work began; 3, gantry Agency: hydraulic cylinder pressure roller compression artifacts, so the wing and the wing web tightly merged orthopedic provide adequate feed into force; 4, orthopedic institution: the pressure roller to achieve the workpiece deformation correction wing eccentric; 5, the feeding mechanism: the production line to send the next workpiece; 6, the hydraulic system: from the pumping station to the assembly, gantry, fine positioning, wire and other agencies to provide the appropriate pressure cylinder; 7, the electrical system: through the PLC programming control of the timing of the drive, solenoid valves, automated H beam production process.
