Description

Technical Field

[0001] This invention relates to the field of cable reel welding technology, and more particularly to a cable reel welding apparatus. Background Technology

[0002] Cable reels are core load-bearing equipment in the production, transportation, storage, and laying of cables. Through their stable structure, they enable the orderly winding and protection of cables, preventing cable twisting, wear, knotting, or damage. They also facilitate loading, unloading, transfer, and construction use, ensuring the safe and reliable transmission of power and communication, and improving the efficiency of cable storage, transportation, and engineering installation. They are an indispensable basic tooling equipment in the cable industry. Cable reels require welding during production, which involves firmly connecting the reel's cylinder, side plates, and other components to ensure the overall structural strength and rigidity, preventing deformation and cracking during cable winding and transfer. During operation, each sheet metal part is first precisely positioned and clamped, and then, depending on the thickness of the sheet metal, methods such as arc welding are selected to weld along the weld seam in sequence. Before welding, the surfaces of the fixed cylinder and side plates are generally sprayed with an anti-rust coating outside the welding area.

[0003] In existing welding equipment, when welding cable reels, the welding area on the side of the fixed cylinder is first ground, followed by grinding the inner side of the annular side plate. Then, the side plate is fixed to the welding area on the side of the fixed cylinder using a clamp. Finally, arc welding is performed on the weld seam using a welding gun. This method generally uses a symmetrical and uniform welding method to ensure that the center of gravity of the side and the fixed cylinder is consistent before and after welding. However, when the center of gravity of the fixed cylinder and the side is inconsistent, the weld seam needs to be ground after welding, which increases the production cost of the reel and is cumbersome. When grinding and adjusting the center of gravity of the uncoated weld area, the connection strength between the fixed cylinder and the side plate is reduced. When welding the fixed cylinder and the side plate with existing welding equipment, air bubbles are prone to appear at the weld seam, reducing the quality of the weld. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The end of the fixed cylinder wobbles within the fourth fixed body. The wobbling amplitude of the fixed cylinder can be detected by four second pressure sensors. The values ​​of the four second pressure sensors are transmitted to the computer through the controller, thereby plotting the center of gravity of the fixed cylinder. At the same time, when the side plate rotates, it will squeeze the first pressure sensor. The center of gravity of the side plate can be plotted by the values ​​of the four first pressure sensors. In order to improve the winding performance of the wire spool after welding, it is necessary to ensure that the center of gravity of the wire spool after welding is consistent with the central axis of the fixed cylinder. Start the welding gun and feeder to weld the seam. The welding speed is controlled according to the center of gravity of the side plate and the fixed cylinder. The quality change at the weld can be controlled according to the welding speed. When the welding speed at a certain point is slow, the mass at that point can be increased, thereby adjusting the center of gravity of the wire spool so that the center of gravity of the wire spool after welding is consistent with the central axis of the fixed cylinder. This prevents the overall connection performance from being reduced when grinding the exposed weld seam later, reduces the subsequent grinding and centering steps, and improves production efficiency.

[0017] 2. When the side plate and the fixed cylinder are rotated, the circumferential welding can carry the air bubbles in the molten metal to the inner side, and then the gas enters the air, thereby greatly reducing the probability of air bubbles appearing during welding and improving the connection strength between the side plate and the fixed cylinder after welding.

[0043] Specifically, the fourth motor 35 drives the threaded rod 34 to rotate, and the threaded rod 34 cooperates to drive the limiting plate 32 to move along the second slot 31. The second slot 31 drives the ninth electric telescopic rod 36 to move towards the end of the fixed cylinder. At the same time, the ninth electric telescopic rod 36 is extended and retracted according to the height of the fixed cylinder, so that the opening end of the fourth fixed body 312 corresponds to the position of the fixed cylinder. When the interior of the fourth fixed body 312 is located at the end of the fixed cylinder, the four multi-stage electric telescopic rods 314 are extended. The four multi-stage electric telescopic rods 314 respectively drive the rollers 316 through the fifth fixed body 317 to squeeze the side of the fixed cylinder.

[0044] In use, the main body plate 1 is placed on a horizontal surface. Then, the end of the fixing cylinder is placed inside the first fixing body 23. At the same time, several fifth electric telescopic rods 226 extend. The four fifth electric telescopic rods 226 are pressed and fixed to the side of the fixing cylinder by the pressing plate 227. Then, the annular side plate is placed on the welding area of ​​the side of the fixing cylinder.

[0045] At this time, the first motor 210 is activated, driving the connecting rod 212 to rotate. The connecting rod 212 drives the first fixed body 23 to rotate, thereby driving the fixed cylinder and side plate to rotate. At this time, the second motor 214 extends, driving the first top block 215 to rotate and limit the end of the fixed cylinder. The fifth electric telescopic rod 226 retracts. When the fixed cylinder rotates, the end of the fixed cylinder sways within the fourth fixed body 312. The swaying amplitude of the fixed cylinder can be detected by the four second pressure sensors 315. The values ​​of the four second pressure sensors 315 are transmitted to the computer through the controller, thereby drawing the center of gravity of the fixed cylinder. At the same time, when the side plate rotates, it will squeeze the first pressure sensor 234. The center of gravity of the side plate can be drawn by the values ​​of the four first pressure sensors 234. In order to improve the winding performance of the wire spool after welding, it is necessary to ensure that the center of gravity of the wire spool after welding is consistent with the central axis of the fixed cylinder. At this time, the sixth electric telescopic rod 229 is activated, driving the gear 231 to rotate. 1. The rotating ring 230 is driven to rotate. A third electric telescopic rod 217 is fixedly connected to the side of the rotating ring 230. The third electric telescopic rod 217 drives the fourth electric telescopic rod 218 to extend. At the same time, the third motor 224 drives the welding gun 223 to rotate to the position aligned with the weld. The welding gun 223 and the feeder 222 are started to weld the weld. The welding speed is controlled according to the center of gravity of the side plate and the fixed cylinder. The quality change of the weld can be controlled according to the welding speed. When the welding speed of a certain place is slow, the mass of that place can be increased, thereby adjusting the center of gravity of the wire spool so that the center of gravity of the wire spool after welding is consistent with the central axis of the fixed cylinder. This prevents the overall connection performance from being reduced when grinding the exposed weld, reduces the subsequent grinding and centering steps, and improves production efficiency. When the side plate and the fixed cylinder are rotating and performing circumferential welding, the air bubbles in the hot molten metal during welding can be carried to the inner side. Then the gas enters the air, thereby greatly reducing the probability of air bubbles appearing during welding and improving the connection strength between the side plate and the fixed cylinder after welding.
