Description

technical field [0001] The invention relates to the field of strip surfacing equipment, in particular to a strip submerged arc surfacing equipment. Background technique [0002] The surfacing head part of the current welding machine surfacing equipment cannot complete the rotary motion around its axis, therefore, the welding strip cannot be twisted by 90°, and the surfacing welding in two directions cannot be realized on the workpiece to be welded. The used welding strip generally has the problem of uneven thickness, and the existing strip submerged arc surfacing machine head cannot adjust the gap at the contact tip, and cannot adjust the pressing force and stabilize the contact with the welding strip at the end. The situation will cause the welding quality of the ribbon conveying to be less stable. [0003] When the existing strip surfacing equipment is welding, the welding strip is sent into the wide and fixed matching area between the welding strip driving wheel and the ...

AI Technical Summary

Problems solved by technology

[0002] The surfacing head part of the current welding machine surfacing equipment cannot complete the rotary motion around its axis. Therefore, the welding strip cannot be twisted by 90°, and the surfacing welding in two directions cannot be realized on the workpiece to be welded.

The used welding strip generally has the problem of uneven thickness, and the existing strip submerged arc surfacing machine head cannot adjust the gap at the contact tip, and cannot adjust the pressing force and stabilize the contact with the welding strip at the end. The situation will cause the welding quality of the ribbon conveying to be unstable

[0003] When the existing strip surfacing equipment is welding, the welding strip is sent into the wide and fixed matching area between the welding strip driving wheel and the pressing wheel, and the welding strip driving wheel transmits the power from the DC motor and the reducer, and is compressed The handwheel adjusts the pressing wheel assembly, adjusts the pressing force of the pressing wheel on the welding belt, and relies on the friction between the driving wheel and the pressing wheel to make the welding belt move vertically downward. To ensure normal belt feeding, the driving wheel and the pressing The pressure exerted by the wheel on the welding strip is moderate, too tight will cause indentations on the surface of the welding strip and affect the welding quality, and too loose will cause the welding strip to slip and cause the supply to be cut off. The tightening wheel needs to be adjusted manually, and the adjustment requirements for the debugging personnel are relatively high, which also leads to more time spent on assembly and debugging, and may require multiple adjustments to meet the production requirements

The electrode has serious heat during the welding process and is easily deformed, resulting in the inability to stably compress the welding strip

The arc burning point is generally in an irregular swimming state, which will lead to an unbalanced heating state at both ends of the welding strip, resulting in poor weld formation and slag inclusions at the edge
