H-beam automatic welding production lines: one type H beam production line, also known as H-shaped steel mini-automatic welding production lines, is a dedicated device for welding T, H-type structural steel. This production line at the same station on consecutive complete T, H-beam automatic group in the production process of legislation, automatic alignment, welding, orthopedic, discharging and all other processes. The entire production process technology smooth, high precision, reasonable layout, small footprint, easy operation, high degree of automation. The main technical features innovations: 1, H-beam welding production methods is H-shaped steel according to "work" type place, on both sides simultaneously welding two corner joints, greatly increasing the welding efficiency. Because of symmetry soldering, after the web fundamental deformation; 2, orthopedic institutions achieve through the eccentric roll butt angle after hot deformation of H-beam flange direct correction, reducing the corrective force to improve the correction accuracy and thickness; 3, using a set of vertical - Welding - correction in an integrated manner, small footprint, eliminating the need for inter-process flow, improve production efficiency; 4, in the web and flange plate of 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 traveling motor with variable frequency drive, smooth courier, welding quality; 7, the web use under hydraulic pressure, and elevating screw with the realization of variable cross-section steel welding. The main technical parameters: 1, H-beam height: 200 ~ 2000mm; 2, H-beam length: 6000 ~ 15000mm; 3, web thickness: 6 ~ 40mm; 4, flange width: 200 ~ 800mm; 5, wing thickness: 6 ~ 40mm; 6, courier range: 400 ~ 1000mm / min; 7, Effective length: 15000mm; 8, the total power: 150KW (including two DC1000 welder); 9, welding position: horizontal angle seam; 10, welding way: double-sided automatic submerged arc welding; 11, welding power source: a single wire submerged arc welding, bilateral 1000A; 12, Speed: AC inverter; 13, program control: PLC; 14, the torch angle: 30 ° - 60 ° can fine-tuning. Production line configuration structure features: 1, assembly mechanism: The motor, reducer, chain, sprocket drive transmission roller transmission welding work to achieve and realize the flange and web of automatic positioning by a hydraulic cylinder drive linkage mechanism, enabling the workpiece welding group legislature; 2, welding mechanism: The motor, reducer, chain, sprocket drive transmission roller welding work to achieve traction. By hydraulic rod and screw vice clamp the workpiece to ensure correct positioning of the workpiece. Gun feed mechanism by the cylinder into the welding position, two welders welding work began; 3, gantry mechanism: cylinder drive roll pressed parts, so that the wing merged with the web tightly orthopedic wing to provide enough feed into force; 4, orthopedic institution: to realize the welding work roll distortion correction wing eccentric; 5, the feeding mechanism: to send the next welding work production line; 6, the hydraulic system: pumping station to assembly, gantry, fine Location, wire and other agencies to provide the appropriate pressure cylinders; 7, the electrical system: The timing PLC programming control inverter, solenoid valves, automated H-beam production process.
