Description

Technical Field

[0001] The utility model relates to the technical field of angle steel nut production, in particular to an automatic welding machine for angle steel nuts. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two perpendicular sides forming an angle. National standard angle steel is defined as one with a minimum deviation of 0.25 mm from the national standard. Angle steel also comes in equal and unequal leg angles. With the acceleration of urbanization, the demand for elevators is increasing. Formed angle steel is a component of elevator columns and must be welded with matching nuts before use.

[0003] However, the welding of related angle steel nuts is generally done manually, which is inconvenient for automatic feeding and discharging of angle steel and nuts, resulting in a low degree of automation and low welding efficiency. In addition, it is inconvenient to firmly fix the nut on the angle steel during welding, and it is easy to deviate during welding, which affects the welding quality. Therefore, we propose an automatic angle steel nut welding machine to solve the above problems. Utility Model Content
