Description

Technical Field

[0001] The present invention relates to the technical field of self-baking electrode welding manufacturing, and particularly relates to an automatic clamping, shaping and butt-jointing device dedicated to a self-baking electrode barrel. Background Art

[0002] A self-baking electrode is composed of an electrode barrel and electrode paste added into the electrode barrel. During the production process of an electric calcium furnace, the electrode paste below the conductive clamp is baked into a mature carbon electrode through resistance heat, conduction heat and radiation heat, and is continuously consumed under the action of the end arc. It is necessary to continuously weld an electrode barrel on the upper part of the electrode barrel and continuously add electrode paste into the electrode barrel to form a continuously produced self-baking electrode.

[0003] When welding the electrode barrel, it is necessary to clamp and lift the electrode barrel. At present, the common clamping and lifting of the electrode barrel is carried out by a traveling crane. During lifting, it is necessary to clamp and lift through straps and hooks. During the lifting process, the electrode barrel is extremely easy to shake and is unstable. Moreover, during the lifting process, workers also need to manually perform operations such as binding, hooking, unbinding, and unhooking, which is inconvenient to operate and has low work efficiency. The shape of the electrode barrel is a hollow cylindrical barrel, and a plurality of convex ribs are uniformly arranged on the outer cylindrical surface. The electrode barrel is made of thin steel plates. Due to the shaking and instability during the existing clamping and lifting and the structure of the electrode barrel itself, it is relatively easy to deform, resulting in certain inconvenience during welding. Therefore, it is necessary to first shape the deformed part to align it with the original electrode barrel before welding. When welding an electrode barrel on the upper part of the electrode barrel, it is necessary to ensure that the outer cylindrical surfaces of the two electrode barrels are round and aligned and the convex ribs are aligned before welding. At present, workers use hand-held tools to manually round and align the outer cylindrical surface of the electrode barrel, and workers use hand-held clamping tools to manually align and clamp the convex ribs. Manual operation is time-consuming and laborious, with a large work intensity, and cannot achieve quick and effective alignment and clamping. It can be seen that at present, the operations of clamping, lifting, shaping and butt-jointing of the electrode barrel mainly rely on manual intervention, lacking corresponding automated mechanical devices.

[0004] Therefore, it is very meaningful to design and manufacture an automatic clamping, shaping and butt-jointing device dedicated to a self-baking electrode barrel to improve the clamping and lifting efficiency, prevent deformation, and automatically perform rounding, alignment and clamping operations.
