Description

Technical Field

[0001] The utility model relates to the technical field of metal material welding, in particular to a welding device for ferrous metal smelting and rolling products. Background Technique

[0002] Ferrous metal smelting and rolling products refer to products obtained by subjecting ferrous metal raw materials such as iron ore and manganese ore to a series of complex chemical reactions and physical processes to extract metals such as iron and manganese, and subjecting the metal billets to pressure processing, passing them through equipment such as rolling mills to change their shapes, sizes, and properties, and producing various products such as plates, pipes, and profiles.

[0003] The welding of ferrous metal smelting and rolling products is a key manufacturing process, aiming to weld ferrous metal components after smelting and rolling processes together through welding technology. In the existing welding process, it is necessary to first ensure the surface cleanliness of the welded workpieces, then prepare the welding equipment and the required welding materials, then determine the first welding surface and perform welding. After welding is completed, the welded parts are flipped or repositioned to expose the other surface to be welded. Then, welding preparation is carried out on the new surface, and welding of the welding surface is repeated. After welding is completed, the welding quality is inspected to ensure that all welds meet the requirements.

[0004] Traditional devices require a large amount of manual adjustment and control, especially when changing the surface or repositioning the welded parts. This not only increases the complexity and time consumption of the operation, but also increases the burden on the operators and the possibility of errors. During welding, the welded parts are basically placed on a workbench or other flat platforms, and manual support of the welded parts is required for welding, making it difficult to achieve comprehensive and stable welding, affecting the uniformity and consistency of welding, and reducing the welding quality and efficiency. Content of the Utility Model

[0005] In view of the problem that manual turning over during welding easily leads to quality problems of the welded parts, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: A welding device for ferrous metal smelting and rolling products, including a base, and two metal pipes horizontally placed above the base and aligned at both ends. It also includes two support frames that are telescopically and slidably installed above the base and can adjust the distance between them, and a welding head arranged at the upper end of the base that can lift and slide to weld the aligned parts of the two metal pipes;

[0007] Two fixing mechanisms are arranged at the upper ends of the support frames, including fixing rings installed on the corresponding support frames. A plurality of fixing rods that can radially expand and contract along the corresponding fixing rings and press against the surfaces of the corresponding metal pipes are slidably inserted into the fixing rings;

[0008] The rotating mechanism includes a connecting ring provided on one side of one of the fixed rings. A sliding ring is provided on the connecting ring. Two groups of sliding wheels are symmetrically and slidably provided on the sliding ring. A rack is provided on the sliding ring, and the rack is meshed with a second gear.

[0009] Preferably, a sliding plate is commonly installed at one end of the two groups of sliding wheels away from the fixed ring. A second motor is provided on the sliding plate, and a rotating rod connected to the output end of the second motor is provided on the second gear.

[0010] Preferably, a connecting member is provided at one end of the sliding plate. A second electric telescopic rod is provided on the connecting member. The output end of the second electric telescopic rod is connected to a fixed block, and a first electric telescopic rod with an output end connected to a welding head is embedded in the fixed block.

[0011] Preferably, a rotating wheel is provided on one side of the fixed ring. A plurality of sliding grooves are formed in the rotating wheel, and sliding rods slidably arranged in corresponding sliding grooves are installed on one side of the fixed rod.

[0012] Preferably, a first gear meshed with the corresponding rotating wheel is rotatably provided on each of the support frames. A first motor is provided at one end of the support frame away from the first gear. A connecting rod connected to the output end of the first motor is provided on the support frame. A sliding groove is formed on the outer peripheral surface of the connecting rod, and a slider is provided on the first gear away from the first motor.

[0013] Preferably, a placement groove is formed on the base. A third motor is installed in the placement groove. The output end of the third motor is connected to a threaded rod rotatably installed in the placement groove and threadedly connected to one of the support frames. Sliding rails slidably connected to the support frame are provided on both sides of the threaded rod at the lower end of the placement groove.

[0014] The beneficial effects of the present utility model:

[0015] 1. Drive the second motor to make the second gear rotate on the rack, and drive the sliding wheels on the sliding plate to perform a circular motion on the sliding ring. At the same time, the second electric telescopic rod drives the first electric telescopic rod to extend and retract to the welding position of the metal pipe. Then, the first electric telescopic rod drives the welding head to contact the metal pipe, so that the welding head can directly complete the comprehensive welding work on all welding surfaces of the metal pipe without manually rotating the surface.

[0016] 2. When the metal pipe needs to be welded, the metal pipes with different outer diameter specifications can be clamped and fixed by sliding the fixing rod in the fixing ring. At the same time, the support frame drives the fixing mechanism and the rotating mechanism to slide in the placement groove, so that the welding parts of the metal pipes are in contact with each other, realizing the extrusion fixation and welding of metal pipes with different length specifications and outer diameter specifications, ensuring that the welding parts of the metal pipes always maintain a stable contact state during welding, and improving the welding quality and efficiency.
