Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a high-frequency pulse welding repair equipment with a wear detection structure. Background Art

[0002] High-frequency welding refers to a welding method that uses high-frequency current to generate resistance heat flowing through the contact surface of the workpieces, and applies pressure (or no pressure) to connect the metal of the workpieces. High-frequency welding is needed when connecting two pipes. The high-frequency module is used to heat the welding position so that the solder melts at the connection position of the two pipes, thereby ensuring the welding effect. Traditional high-frequency welding is to manually insert a thin tube into a thick tube, and then use the solder to melt at the connection position. The melted solder will fill the docking position, and welding can be achieved after cooling. For example, patent announcement CN220347621U discloses a metal fitting welding device, which records a structure for welding two pipe ends. However, this welding method requires staff to continuously load materials. After welding, the staff also needs to pull out the welded pipe fittings from one side, which is inconvenient to load and unload materials.

Here, the high-frequency welding clamp 300 can heat the ends of the two welding pipes 109, that is, Figure 4 Pipe fitting A and pipe fitting B in;

[0038] A feeding roller 401 for winding a solder wire strip 402 is provided above the high-frequency welding clamp 300. The free end of the feeding roller 401 passes through a guide ring sleeve 404 and extends to the docking position of two welding tubes 109. One side of the guide ring sleeve 404 is connected to a guide positioning rod 405. The other end of the guide positioning rod 405 is connected to a welding bracket. Two extrusion feeding rollers 407 are rotatably provided above the guide ring sleeve 404. A transmission gap for transmitting the solder wire strip 402 is provided between the two extrusion feeding rollers 407. A conveying groove is provided on the outer side of the extrusion feeding roller 407. The extrusion feed roller 407 is connected to a feed motor 406 for driving the feed motor 406 to rotate. The feed motor 406 is arranged on a mounting plate. The other side of the mounting plate is connected to a welding bracket. The shaft end of the feed roller 401 is rotatably connected to the welding bracket. When in use, the extrusion feed roller 407 is driven to rotate by the feed motor 406. The friction between the extrusion feed roller 407 and the solder wire 402 drives the solder wire 402 to move toward the welding position of the welding tube 109. The end of the solder wire 402 is heated and melted by the high-frequency welding clamp 300, and then the pipe A and the pipe B are welded.

[0039] The feeding component includes a transfer arc plate 107 arranged above the feeding roller 105. There is a transfer gap between the transfer arc plate 107 and the feeding roller 105 so that the welding pipe 109 can be transferred with the feeding roller 105. The top of the transfer arc plate 107 is connected to the feeding notch groove 110. One side of the feeding notch groove 110 is provided with an inclined feeding guide plate 108. The lower end of the feeding guide plate 108 is connected to the base 100 through the feeding leg 106. The feeding guide plate 108 is provided with a The buffer slope is used to buffer the welded tubes 109. Under the action of gravity, the welded tubes 109 are accumulated on the feeding guide plate 108. When the feeding notch 104 on the feeding roller 105 is transferred to the feeding notch groove 110, the lowermost welded tube 109 will be filled into the feeding notch 104 to complete the single feeding. This feeding method can realize the synchronous feeding of two welded tubes 109, and the two welded tubes 109 will be coaxially arranged, which is also convenient for the end butt joint of the welded tubes 109 in the later stage.

[0040] The rotary drive member includes a rotating worm wheel 103 arranged at the axial end of the feeding roller 105. The two feeding rollers 105 are connected by a transmission shaft to realize the synchronous rotation of the two feeding rollers 105. The lower side of the rotating worm wheel 103 is meshed with the rotating worm 101. The two ends of the rotating worm 101 are rotatably connected to the auxiliary plate at the upper end of the base 100. The auxiliary plate is provided with a first rotating motor 102 for driving the rotating worm 101 to rotate. The rotating worm 101 is driven to rotate by the first rotating motor 102. The rotating worm 101 matches the rotating worm wheel 103, thereby driving the feeding roller 105 to rotate. The rotating worm wheel 103 and the rotating worm 101 here match to realize transmission and have a self-locking function.

[0041] Working principle: in actual use, the welding pipe 109 to be processed is placed in the cache position of the feeding guide plate 108, and there is no need for manual feeding by the staff later. The feeding roller 105 is driven to rotate by the rotating driving member. During the rotation of the feeding roller 105, the welding pipe 109 at the lower side will be filled into the feeding gap 104 on the surface of the feeding roller 105, and then the welding pipe 109 in the feeding gap 104 will be transferred to the welding position, and the extrusion feeding roller 407 is driven to rotate by the feeding motor 406. The friction between the extrusion feeding roller 407 and the solder wire 402 will drive the solder wire 402 to move toward the welding position of the welding pipe 109, and the end of the solder wire 402 will be heated and melted by the high-frequency welding clamp 300, and then the pipe A and the pipe B are welded. During the welding process, the vertical slide 501 is first driven to move toward the feeding roller 105 by the displacement mechanism. When the positioning head 507 is inserted into the welding pipe 109, it is driven by the cylinder push rod 513 The piston plate compresses the internal space of the inflatable cylinder 510, so that the grinding block 508 at the end of the positioning head 507 extends outward, thereby fixing the welding tube 109 from the inside, and then pushes the ends of the two welding tubes 109 close together, such as the docking state of the pipe fitting A and the pipe fitting B. During welding, the two welding tubes 109 can also be driven to rotate synchronously, thereby ensuring the welding effect of the ends of the two welding tubes 109. After welding is completed, when the welding tube 109 is initially cooled, the welding tube 109 is locked by one of the grinding blocks 508, and then the other is used to push the cross tube 505 into the welding position of the welding tube 109, and the welding state inside the welding position is obtained by the camera module 506. Then, the positioning head 507 can be driven to rotate quickly, and the grinding end of the grinding block 508 can be used to grind the inner wall of the welding tube 109 to ensure the smoothness of the inner wall of the welding tube 109. The smoothness of the inner wall of the welding tube 109 can also be detected by the camera module 506.

[0042] After welding is completed, the high-frequency welding clamp 300 is driven downward by the welding push rod 301. After the two welding tubes 109 are cooled, the two loading rollers 105 continue to rotate. When they rotate to the end position of the transfer arc plate 107, the two welded tubes 109 will slide down along the material guide plate 200, thereby completing automatic unloading.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
