Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary rotating devices, specifically relating to an auxiliary rotating device for electroslag bar welding. Background Technology

[0002] Electroslag rods are an important material in the electroslag remelting process. Generally, the electroslag rods are welded to the electrodes and then placed vertically into the remelting furnace for electroslag remelting. Therefore, the electroslag rods need to be supported and rotated during the welding process with the electrodes. Usually, an auxiliary rotating device is used to support and rotate the welding process. The existing auxiliary rotating device is used to assist in supporting and rotating the electroslag rods during the welding process with the electrodes.

[0003] Existing auxiliary rotating devices, when used for welding electroslag rods to electrodes, reveal a Chinese invention patent (CN119457687A) that designs a rotary welding positioning fixture. This fixture includes a support frame, base, reduction gear, servo motor, and a rotating component capable of rotating 360° axially and radially along the workpiece. This fixture provides the optimal welding position, ensuring welding accuracy, consistency, and stability. However, this welding positioning fixture can only position and rotate small to medium-sized workpieces and cannot be used for positioning and rotating electroslag rods.

[0004] Chinese invention patent CN119501452A designs a rotary welding device for drill barrels. Its structure includes two rotating tables, each of which can be used to clamp two parts and rotate them. Welding components are set on the frame around the rotating tables, which can simultaneously perform the rotation and welding process of the workpiece. However, its limitation is still the limitation of the workpiece size, which makes it impossible to perform rotary welding of large-sized workpieces. It is known that rotary welding of large-sized workpieces cannot be achieved during welding, especially for large-sized electroslag rods with long lengths and large diameters. The rotary auxiliary device is still lacking, which affects the convenience of the auxiliary rotation device in assisting the rotation of large-sized electroslag rods and electrodes during welding. Therefore, this utility model proposes an auxiliary rotary device for electroslag rod welding. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: an auxiliary rotating device for electroslag bar welding, comprising an auxiliary rotating device body 100, the auxiliary rotating device body 100 including a main frame 101 and an electrical control box 106, a rotating drive mechanism 102 fixedly mounted on one end of the upper surface of the main frame 101 by mounting bolts, a motor 103 provided at the tail end of the rotating drive mechanism 102, and the motor 103 electrically connected to the electrical control box 106 by wires, a lubrication device 105 internally connected and sealed to facilitate lubrication of the rotating drive mechanism 102 during long-term operation by the lubrication device 105, a protective shell 104 fixed to the front end of the rotating drive mechanism 102 by mounting bolts, and the auxiliary rotating device body 100 also being provided with:

[0028] The welding rotation mechanism includes an auxiliary support assembly disposed on one side of the main frame 101. An active rotation assembly is disposed at the connection point between the top of the auxiliary support assembly and the two ends of the upper surface of the main frame 101. A sliding assembly is disposed on one side of the support assembly, and an auxiliary rotation assembly is disposed on the upper surface of the sliding assembly. The welding rotation mechanism can support and rotate the electroslag rod for complete welding during the welding process, which facilitates the use of auxiliary rotation welding.

[0029] In order to facilitate the support and rotation adjustment of the other end of the main rotating roller 1012 by means of an auxiliary support assembly, in this embodiment, preferably, the auxiliary support assembly includes an auxiliary support plate 1018 disposed on one side of the main frame 101. The auxiliary support plate 1018 and the bottom edge of the main frame 101 are both welded with triangular brackets. The main frame 101 and the auxiliary support plate 1018 are at the same height. The other end of the main rotating roller 1012 can be installed and assisted in driving operation through the auxiliary support plate 1018.

[0030] To facilitate the driving and rotation adjustment of the electroslag rod through the active rotation component, and to facilitate gas shielded welding, in this embodiment, preferably, the active rotation component includes mounting covers 1011 fixedly installed at both ends of the upper surface of the main frame 101 and the auxiliary support plate 1018. A main rotating roller 1012 is mounted at the connection of the two mounting covers 1011 through a bearing. The end of the main rotating roller 1012 is fixed to the output shaft of the drive end of the rotation drive mechanism 102 through mounting bolts. When the rotation drive mechanism 102 drives the main rotating roller 1012, the main rotating roller 1012 drives the electroslag rod to rotate, facilitating rotation for surrounding welding.

[0031] To facilitate the adjustment of the position of the top plate 1015 and the auxiliary support rotating roller 1016 via the sliding assembly, in this embodiment, preferably, the sliding assembly includes two slide rails 1013 disposed on one side of the auxiliary support plate 1018. Limit blocks are provided at the ends of the slide rails 1013. Three base plates 1014 are disposed at the connection point of the two slide rails 1013. Rollers 1019, corresponding to the slide rails 1013, are fixed to both ends of the lower surface of the base plates 1014 by mounting bolts. The rollers 1019 can roll on the surface of the slide rails 1013, passing through the base plates 1014, thereby moving the top plate 1015 and the auxiliary support rotating roller 1016 to the support position for easy adjustment and use.

[0032] To facilitate auxiliary support and rotation adjustment of the electroslag rod using the auxiliary rotation assembly, in this embodiment, preferably, the auxiliary rotation assembly includes hydraulic lifting rods 1017 fixedly mounted at both ends of the upper surface of the base plate 1014. A top plate 1015 is fixed to the top connection of the two hydraulic lifting rods 1017 by mounting bolts. Auxiliary support rotating rollers 1016 are mounted at both ends of the upper surface of the top plate 1015 by bearings, and the two auxiliary support rotating rollers 1016 are symmetrically arranged. The top plate 1015 and the auxiliary support rotating rollers 1016 can be adjusted to the same height as the main rotating roller 1012 by the hydraulic lifting rods 1017, and can provide auxiliary support and rotation operation for electroslag rods with larger diameters and longer lengths on the surface of the auxiliary support rotating rollers 1016.

[0033] The wear-resistant and anti-slip mechanism includes two sets of wear-resistant and anti-slip components disposed on the outer surface of the active rotating component. The ends of the two sets of wear-resistant and anti-slip components are provided with fixed installation components at the connection between them and the active rotating component. When the main rotating roller 1012 rotates the electroslag rod, the wear-resistant and anti-slip mechanism rotates the electroslag rod on the surface of the main rotating roller 1012 in a wear-resistant and anti-slip manner, making it less prone to slippage during rotation and ensuring stable rotation welding.

[0034] In order to facilitate wear-resistant treatment of the outer surface of the main rotating roller 1012 through the wear-resistant and anti-slip component, and to prevent the main rotating roller 1012 from slipping during rotation, in this embodiment, preferably, the wear-resistant and anti-slip component includes wear-resistant protective plates 107 disposed on both sides of the outer surface of the main rotating roller 1012. The outer surface of the wear-resistant protective plate 107 is provided with wear-resistant and anti-slip protrusions 1071 at equal intervals. When the main rotating roller 1012 rotates and drives the electroslag rod to rotate, the surface of the electroslag rod is directly in contact with the wear-resistant protective plate 107 and the wear-resistant and anti-slip protrusions 1071 for wear-resistant and anti-slip treatment, and slippage is not easily generated during rotation welding.

[0035] To facilitate the fixed installation of the wear-resistant protective plate 107 and the wear-resistant anti-slip protrusion 1071 using a fixed installation assembly, in this embodiment, preferably, the fixed installation assembly includes three embedding holes 1072 at both ends of the wear-resistant protective plate 107. A fixing bolt 1073 is provided inside each embedding hole 1072. The outer surface of the main rotating roller 1012 has internally threaded holes 1074 equidistantly spaced on both sides. The internal structure of the fixing bolt 1073 matches that of the internally threaded holes 1074. After the wear-resistant protective plate 107 and the wear-resistant anti-slip protrusion 1071 are closed on the outer surface of the main rotating roller 1012, the fixing bolt 1073, located inside the embedding hole 1072, is rotated to embed into the internally threaded hole 1074, thus fixing the wear-resistant protective plate 107 and facilitating its use.

[0036] The working principle and usage process of this utility model are as follows: When using this electroslag bar welding auxiliary rotation device, the main body 100 of the auxiliary rotation device is first fixedly installed at the usage position, thereby fixing the slide rail 1013 at the operation position installation position. After installation, when it is necessary to weld and assist in the rotation of the electroslag bar, the three sets of base plates 1014 can be slid to the support placement position by the rollers 1019 rolling on the outer surface of the slide rail 1013. Then, the hydraulic lifting rod 1017 drives the top plate 1015 and the auxiliary support rotating roller 1016 to be adjusted to the height corresponding to the support of the main rotating roller 1012. One end of the electroslag bar can be supported and placed at the connection of the two main rotating rollers 1012. The welding end of the electroslag bar extends to one end and is supported between the two auxiliary support rotating rollers 1016. Then, the electrode is supported between the two auxiliary support rotating rollers 1016 at the very end. At this time, the end of the electroslag bar and the end of the electrode are correspondingly set and welded.

[0037] Therefore, during welding, the motor 103 drives the rotary drive mechanism 102, which in turn drives the main rotary roller 1012 to rotate. This facilitates the rotation of the main rotary roller 1012, causing the electroslag rod to rotate between the two main rotary rollers 1012. At the same time, the other end of the electroslag rod is supported and rotated between the two auxiliary support rotary rollers 1016. This allows for continuous rotation of the end of the electroslag rod to complete the welding process between the electrode and the main rotary roller 1016. Thus, the auxiliary support rotation operation is convenient during the welding process of the electroslag rod. Furthermore, the auxiliary rotation between the two main rotary rollers 1012 facilitates the auxiliary rotation of larger diameter and longer electroslag rods, improving the convenience of the auxiliary rotation device body 100 in the welding process of larger-sized electroslag rods and electrodes.

[0038] Finally, before using the auxiliary rotating device body 100, after the main rotating roller 1012 is installed, the two wear-resistant protective plates 107 are correspondingly engaged and installed on the outer surface of the main rotating roller 1012. The fixing bolts 1073 are embedded in the embedded hole 1072 and screwed into the internal thread hole 1074 to fix the wear-resistant protective plates 107 on the outer surface of the main rotating roller 1012. This also facilitates the fixed installation of the wear-resistant protective plates 107 and the wear-resistant anti-slip protrusions 1071. Therefore, when the main rotating roller 1012 rotates frequently to drive the electroslag rod to rotate, the wear-resistant protective plates 107 and the wear-resistant anti-slip protrusions 1071 increase friction and effectively drive the rotation, making it less prone to slippage. This improves the wear-resistant and anti-slip convenience of the auxiliary rotating device body 100 when the main rotating roller 1012 assists in the rotation of the electroslag rod and electrode welding process.
