Double-gun transverse automatic welding device

Abstract

The invention discloses a double-gun transverse automatic welding device. The double-gun transverse automatic welding device comprises a control adjusting panel, a welding gun head, a welding bead hydraulic grinding and drying device, a moving track, a workpiece abutting block, a workpiece abutting cylinder and a working base table, wherein the control adjusting panel is arranged above the workingbase table and connected in a welding mode, and the welding gun head is embedded in the bottom end of the welding bead hydraulic grinding and drying device and is connected with the bottom end of thewelding bead hydraulic grinding and drying device embedded and sleeving modes. According to the double-gun transverse automatic welding device, the welding bead surface is grinded before welding, sothat the uneven welding bead becomes smooth, and the oxide film formed on the welding bead surface due to long-term exposure to air is ground off during grinding, welding bead points are easy to weldand fuse, hot air is blown out to dry the welding bead, the problem that the welding bead is not prone to being welded and fused due to the fact that the welding bead is wet is solved, the blown hot air can timely remove the powder generated by grinding, and the welding quality is ensured.

Description

Technical field [0001] The invention relates to the field of automatic welding devices, and more specifically, is a dual-gun transverse automatic welding device. Background technique [0002] The main machine of double gun automatic girth seam welding adopts horizontal structure, which is mainly composed of base, headbox and rotary drive motor, tooling fixture, welding gun manual fine-tuning cross carriage, tailstock, top tightening cylinder, and electrical control system. This automatic welding device has the following disadvantages: [0003] 1. The welding equipment is easy to make the welding points not fusion when welding the welding parts with uneven welding bead, and the welding bead is easy to be oxidized, and it is not easy to weld, resulting in welding errors. [0004] 2. Because the surface of the welded parts is easily damp, the weld bead is wet, making welding difficult and affecting welding quality. Summary of the invention [0005] In view of the shortcomings of the pr...

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a double-gun horizontal automatic welding device to solve the problem that the welding equipment in the prior art tends to cause the welding points to not fuse when welding a welded piece with an uneven weld bead, and The weld bead is easily oxidized and difficult to weld, resulting in welding errors. Because the surface of the welded part is easily affected by moisture, the weld bead is wet, making it difficult to weld and affecting the welding quality.
