Description

Technical Field

[0001] This utility model belongs to the field of auxiliary tooling technology for electroslag casting, and specifically relates to an electroslag casting anode welding system. Background Technology

[0002] Electroslag metallurgy began to develop rapidly in the 1960s and has a history of over 60 years, encompassing various sub-processes such as electroslag remelting, electroslag casting, and electroslag welding. Electroslag casting is a metallurgical process that completes metal refining and casting in a single step, producing high-quality alloy castings. This technology utilizes the resistance heat generated by an electric current passing through molten slag to continuously melt the metal electrodes. The molten metal gathers into droplets, drips through the slag layer into a molten metal pool, and simultaneously solidifies into a casting within a specially shaped water-cooled mold. It is a near-net-shape forming technology that integrates smelting, purification, and solidification, resulting in castings with excellent metallurgical quality and shapes and dimensions close to or equal to the final product.

[0003] Therefore, consumable electrodes need to be continuously replaced and replenished during the electroslag casting process. In the existing technology, the welding of electrode billets in electroslag furnaces is all done manually. Due to the subjectivity and individual differences of manual operation, human errors are difficult to completely avoid in a high-intensity, fast-paced working environment. These errors may cause product quality problems.

[0004] Therefore, there is an urgent need for an automatic welding system for electroslag casting anodes. Summary of the Invention

[0060] The feed rod 110 is a rod that connects the feed end of the casting system to the billet 100. In the casting system, the function of the feed rod 110 is to carry the billet 100 down into the slag pool.

[0061] Weld joint 120 is the welded part connecting the blank 100 and the material rod 110; please refer to Figure 1In this specific embodiment, the weld joint 120 is not a physical device, but rather the interface position after the blank 100 and the rod 110 are joined. It should be noted that in this embodiment, the end contact surfaces of the blank 100 and the rod 110 need to be relatively flush. If the weld joint 120 is too large, the purpose of automatic welding cannot be achieved.

Under the constraint of the rotating clamp 240, the center position of the blank 100 is fixed, and centering is achieved by lifting and lowering the material rod support device 220.

Of course, in other embodiments, single, three, or six blanks can be constrained into clusters, with an exposed surface to facilitate welding by the industrial robot 300.

[0069] Additionally, it is important to note that although this embodiment partially defines the technical solution as horizontally arranged, for those skilled in the art, the difficulty in overcoming the vertical and horizontal orientations is low, and they should be considered equivalent technical features. That is, the technical solution can be achieved by vertically arranging the material rod support device 220 and other devices using a clamping method.

[0080] In some implementations, please refer to Figure 3 ,

[0081] The rotating clamp 240 includes:

Single or multiple clustered blanks 100 enter the rotating clamp 240. The rod support device 220 is adjusted to align the blanks 100 with the ends of the rod 110, creating a weld joint 120. The industrial robot 300 identifies the position of the weld joint 120, plans the path, and welds. If there is space in the planned path that the industrial robot cannot reach, the rod rotating device 210 or the rotating clamp 240 rotates to rotate the position of the weld joint 120. The industrial robot 300 continues to identify the weld joint 120 and completes the overall welding. The rotating clamp 240 is then opened, and the rod 110 and the blanks 100 are moved to the next station to complete the welding work.
