Problems solved by technology

In production practice, it is found that when the junction of the web and the flange is fully welded, the arc starts at the end of the H-beam prototype, because the power and temperature of the welding torch have not yet reached the target when the arc starts, and it is close to the end The molten pool is easy to flow, so there will be welding defects at the end of the H-shaped steel, and only manual repair welding or manual welding of the arc strike plate can be performed in the follow-up

Embodiment 1

[0041] Embodiment one, with reference to Figure 1-Figure 4 , the H-shaped steel welding method of the H-shaped steel high-efficiency production line, the T-shaped arc-starting plate 1 is welded to the end of the H-shaped steel prototype 2 through the arc-starting plate welding device, and then the arc is started on the T-shaped arc-starting plate 1, and the web 3 and the junction of the wing plate 4 are welded.

[0042] Wherein the arc strike plate welding device comprises a door frame 5, the door frame 5 has a passage for the passage of the H-shaped steel blank 2, and the door frame 5 is provided with a longitudinal movement frame 6, and the longitudinal movement frame 6 can be placed on the Longitudinal movement on the door frame 5 (longitudinal movement refers to the front and rear direction along the conveying direction of the H-shaped steel prototype), in the embodiment, the longitudinal movement frame 6 and the door frame are connected by guide rails, and the longitudin...

Embodiment 2

[0062] Embodiment two, refer to Figure 5-Figure 7 , the arc strike plate conveying device includes a conveyor belt and a positioning plate located on one side of the conveyor belt, the form of the conveyor belt can be a conveyor belt, or a belt-shaped distribution of conveyor rollers, etc., the T-shaped arc strike The vertical plate of the plate 1 rests on the conveyor belt, and the bottom plate 12 of the T-shaped arc-starting plate 1 is located between the conveyor belt and the positioning plate and abuts against the positioning plate to realize the positioning of the T-shaped arc-leading plate At this time, the bottom plate 12 of the T-shaped arc-starting plate has corresponded to the wing plate at the end of the H-shaped steel prototype, and the vertical plate 13 of the T-shaped arc-starting plate has corresponded to the web at the end of the H-shaped steel prototype. As a clamping device, the clamping device described in this embodiment includes a clamping cylinder 28 ins...

Abstract

The invention discloses an H-shaped steel welding method of an H-shaped steel efficient production line. A T-shaped run-on plate is welded to the end of an H-shaped steel prototype through a run-on plate welding device, then arc striking is started on the T-shaped run-on plate, and the junction of a web plate and a wing plate is welded; the run-on plate welding device comprises a portal frame, a longitudinal moving frame is arranged on the portal frame, a transverse moving frame is arranged on the longitudinal moving frame, and a lifting material taking arm is arranged on the transverse movingframe; a bearing table of the T-shaped run-on plate is arranged below the material taking arm, and the T-shaped run-on plate is arranged on the bearing table; and the run-on plate welding device further comprises a welding gun device, during run-on plate welding, the T-shaped run-on plate is picked up through the material taking arm and then sent to the end of the H-shaped steel prototype, and then welding is conducted through the welding gun device. The T-shaped run-on plate is automatically welded to the end of the H-shaped steel prototype through the run-on plate welding device, efficientautomation is achieved, then arc striking is started on the run-on plate, the junction of the web plate and the wing plate is welded, and welding defects are avoided.

Description

technical field [0001] The invention relates to an H-shaped steel welding method for an H-shaped steel high-efficiency production line. Background technique [0002] The applicant of the present application invented a high-efficiency production line for H-shaped steel. After spot welding the web and the flange to assemble the H-shaped steel prototype, the H-shaped steel prototype is sent to the welding device for full welding at the junction of the web and the flange. , and then transported to the correction device to correct the wing. In production practice, it is found that when the junction of the web and the flange is fully welded, the arc starts at the end of the H-beam prototype, because the power and temperature of the welding torch have not yet reached the target when the arc starts, and it is close to the end The molten pool is easy to flow, so there will be welding defects at the end of the H-shaped steel, and only manual repair welding or manual welding of the ar...
