Description

Technical Field

[0001] The utility model relates to the technical field of welding machines, in particular to a steel bar welding machine for construction engineering. Background Art

[0002] A steel bar welding machine is a mechanical device that welds two steel bars together through an electric arc. This connection method has the advantages of good continuity, high strength, small deformation, and simple construction. Therefore, it has gradually become a commonly used steel bar connection method in modern construction.

[0003] During the use of existing steel bar welding machines for construction projects, the steel bars may shake or shift during the welding process, resulting in inaccurate welding position and affecting the welding quality. Therefore, the steel bars need to be fixed. The existing fixing method is to fix the steel bars on the clamps, but the spacing of the clamps is usually fixed. This will result in the inability to effectively fix steel bars of different diameters when welding. The corresponding clamps need to be replaced for operation, which reduces the convenience of use. In addition, the steel bars at both ends need to be fixed and then merged, and welding is performed at the connection. The existing welding mechanism is fixed and immovable. When the welding point is located directly below the welding mechanism, welding can be performed. However, when the different lengths of the steel bars cause the welding points of the steel bars at both ends to be far away from the bottom of the welding mechanism, it is necessary to continuously adjust the position of the steel bar connection point so that it is below the welding mechanism for welding. This brings inconvenience to the welding work and reduces work efficiency. Utility Model Content
