Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of welding technology, and more particularly to a welding device for ferrous metal smelting and rolling products. Background Technology

[0002] Ferrous metals refer to the collective term for iron, manganese, and chromium, primarily iron and its alloys, such as steel, pig iron, ferroalloys, and cast iron. Welding can meet the requirements of various operating environments for large-scale and high-parameter structural materials, while improving the safety performance of structural materials. High-quality welding of smelted and rolled ferrous metal products not only helps improve the overall performance of the products but also expands their application fields, meeting the needs of modern industry for high-performance materials.

[0003] The existing technology includes Chinese invention patent application number 202410660138, titled "A Welding Equipment for Ferrous Metal Smelting and Rolling Products," which describes that "the planar moving device of this invention can drive the rotating device and the workpiece to move forward and backward and left and right in a plane. The rotating device allows the workpiece to be adjusted in three directions: first, the chuck rotates around the axis of the lower rotating seat; second, the chuck rotates with the upper rotating seat and the second ball gear; third, the chuck and the workpiece rotate with the second ball gear around their own axis, thereby allowing the workpiece connected to the chuck to be freely adjusted in space. The rotation of the chuck and the workpiece around their own axis also allows the workpiece and the laser head to move relative to each other, generating feed during welding." However, the chuck described therein achieves multi-directional rotation through a rotating device set at the bottom. The workpiece needs to rotate with the chuck. For long round tubes, they may collide with the bottom device during rotation with the chuck, thus affecting the normal progress of the welding work. Summary of the Invention

[0108] Working principle: When welding a circular pipe, the limiting mechanisms 5 on both sides are pried open, and the circular pipe is inserted into the limiting mechanisms 5. The first limiting post 54, the second limiting post 55, and the third limiting post 56 on both sides apply pressure to the outer wall of the circular pipe 2 workpiece, so that the workpiece is initially fixed. Then, the rocker arm 61 is shaken, and the rocker arm 61 drives the first lead screw 62 to rotate. The first lead screw 62 drives the arc-shaped support rod 66 to move towards the outer wall of the circular pipe 2. When the shim 68 reaches near the outer wall of the circular pipe 2 workpiece, it stops moving. The first fastener 64 is held and rotated. The first fastener 64 drives the second lead screw 65 to rotate. The first fixing block 67 in front of the second lead screw 65 drives the shim 68 to abut against the outer wall of the circular pipe 2 workpiece, further fixing the circular pipe 2.

[0109] If the workpiece to be welded consists of two straight round tubes 2, fix the other part of the workpiece in the same way, and then start the welding mechanism 3 to weld them. If the workpiece to be welded is not two straight round tubes 2, the welding direction needs to be adjusted by adjusting the rotation direction using the adjusting mechanism 4. Press and rotate the surface of the panel 41 at a certain angle, tighten the adjusting screws 42 around the panel 41 so that the adjusting screws 42 abut against the surface of the worktable 1, fix the angle of the panel 41, and then proceed with the remaining welding work. The limiting mechanism and fixing mechanism are not only suitable for round workpieces, but also for other shaped workpieces, such as square tubes and irregular tubes.
