Description

Technical Field

[0001] The utility model relates to a submerged arc welding head device which can weld both H-shaped steel and box beam. Background Art

[0002] H-beam is named because its cross-sectional shape is similar to the English letter "H", while box beam is called box beam because its cross-sectional shape is the same as that of an ordinary box. At present, the welding equipment for H-beam and box beam is not universal, and there is no welding equipment specifically used for welding both H-beam and box beam. It is now necessary to transform the existing welding equipment so as to achieve the purpose of welding both H-beam and box beam. Summary of the invention

[0003] The utility model aims to provide a submerged arc welding head device which can weld both H-shaped steel and box beam, and can solve the technical problems mentioned in the background technology.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a submerged arc welding head device that can weld both H-shaped steel and box beams, including a submerged arc welding head seat, on which a submerged arc welding gun and a flux pipe are provided, and the submerged arc welding head seat can also be detachably mounted with a flux blocking plate located next to the submerged arc welding gun.

[0005] Preferably, a fixing column is vertically fixed on the back side of the flux shielding plate, and the fixing column is movably inserted into a flux shielding frame, and the flux shielding frame is detachably mounted on the submerged arc welding machine head seat, and an elastic part is sheathed on the fixing column to bring the flux shielding plate close to the submerged arc welding gun.

[0006] Preferably, mounting frames are extended downwardly on both sides of the submerged arc welding head seat, and a group of fixing columns and flux blocking frames are provided on the back sides of both sides of the flux blocking plate. The flux blocking frames are in an inverted L shape, and the upper ends of the flux blocking frames are fixed to the corresponding mounting frames.

[0007] Preferably, there are two submerged arc welding guns, one of which is vertically arranged and the other is inclined.

[0008] Compared with the prior art, the utility model has the beneficial effect that when the flux blocking plate is installed, the box beam can be welded, and when the flux blocking plate is removed, the H-shaped steel can be welded, thereby realizing multiple uses of one machine and meeting usage requirements.

[0012] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0013] like Figure 1-Figure 3 As shown, the utility model provides a submerged arc welding head device that can weld both H-beam and box beam, including a submerged arc welding head base 1, on which a submerged arc welding gun 2 and a flux material pipe 3 are arranged, and a flux shielding plate 4 located next to the submerged arc welding gun 2 can also be detachably mounted on the submerged arc welding head base 1. When welding H-beam, the utility model uses an H-beam tooling to install the H-beam under the submerged arc welding gun 2. At this time, the flux shielding plate 4 is removed, and the flux material pipe 3 sprinkles the flux on the place where the H-beam needs to be welded, and at the same time, the submerged arc welding gun 2 uses a ship-shaped welding position to weld the H-beam. When welding the box beam 5, the utility model installs a flux shielding plate 4 on the submerged arc welding machine head seat 1, and uses the box beam fixture to install the box beam 5 under the submerged arc welding gun 2. At the same time, the flux shielding plate 4 leans against the side of the box beam 5 that needs to be welded, and the flux material pipe 3 sprinkles the flux on the position where the box beam 5 and the flux shielding plate 4 contact. The flux shielding plate 4 can help the flux to be stacked at the welding position of the box beam 5 that needs to be welded, and the submerged arc welding gun 2 can weld the box beam 5. During the welding process of the utility model, the submerged arc welding machine head seat 1 moves relative to the H-beam fixture and the box beam fixture. When the flux shielding plate 4 is installed, the box beam 5 can be welded, and when the flux shielding plate 4 is removed, the H-beam can be welded, so that one machine can be used for multiple purposes and meet the use requirements.

[0014] Preferably, a fixing column 6 is vertically fixed on the back side of the flux shielding plate 4, and the fixing column 6 is movably inserted into a flux shielding frame 7. The flux shielding frame 7 is detachably mounted on the submerged arc welding head seat 1, and an elastic member 8 is sheathed on the fixing column 6 to bring the flux shielding plate 4 close to the submerged arc welding gun 2. The elastic member 8 is preferably a spring, and the elastic force of the spring can make the flux shielding plate 4 close to the box beam 5 to ensure the welding quality.

[0015] Preferably, mounting frames 9 are extended downward on both sides of the submerged arc welding head seat 1, and a group of fixing columns 6 and flux blocking frames 7 are provided on the back of both sides of the flux blocking plate 4. The flux blocking frames 7 are in an inverted L shape, and the upper ends of the flux blocking frames 7 are fixed to the corresponding mounting frames 9, with a simple structure.

[0016] Preferably, there are two submerged arc welding guns 2, one of which is vertically arranged and the other is inclined. According to needs, one of the submerged arc welding guns can be selected to work, or both of them can be used to meet usage requirements.

[0017] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and the implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
