Its technical points are: including a rotating shaft, a mounting assembly, a disassembly assembly and a wire guide assembly. The end of the rotating shaft is connected to a sliding rod, and a baffle is slidably connected to the sliding rod. When installing the welding wire reel, by passing two sets of baffles through the sliding rod respectively, the mounting assembly can be compressed on the sliding rod during the sliding process of the baffle on the sliding rod.

Under the action of the first spring, the first semicircular block and the second semicircular block can move dynamically according to the winding route of the welding wire, ensuring that the welding wire is always on the winding route, avoiding the welding wire from being misplaced during the wire feeding process, not only ensuring the normal transportation of the welding wire, but also ensuring the welding efficiency;

[0020] 2) When the new welding wire reel is in use, when the welding position of the metal part changes, the welding head corresponds to the welding position and needs to move.

A spring 10, the rotating column 3 follows the wire feeding and rotates the welding wire to squeeze the first semicircular block 7, so that the rotating rod 6 retracts and compresses the first spring 10 connected to the surface of the first semicircular block 7, and the first spring 10 on the surface of the second semicircular block 8 will reset, and then move the second semicircular block 8 toward the first semicircular block 7. At this time, the rotating rod 6 connected to the second semicircular block 8 extends out. When the welding wire squeezes the second semicircular block 8, the process is opposite to the above-mentioned step of the welding wire squeezing the first semicircular block 7. Under the action of the first spring 10, the first semicircular block 7 and the second semicircular block 8 can dynamically move according to the winding route of the welding wire, ensuring that the welding wire is always on the winding route, avoiding the dislocation of the welding wire during the wire feeding process, not only ensuring the normal transportation of the welding wire, but also ensuring the welding efficiency.

[0027] Bearings 4 are provided at both ends of the rotating column 3 , and the rotating column 3 is rotatably connected to the fixed plate 2 via the bearings 4 . The bearings 4 are conventional bearings 4 in the prior art, and the bearings 4 ensure the smooth movement of the rotating column 3 .

[0028] The rotating rod 6 is a multi-stage telescopic rod, and the rotating rod 6 can achieve multi-stage telescopic movement.

[0029] The use steps of the utility model are as follows: when the new welding wire reel is in use, in the initial state, the first spring 10 is in a compressed state. When the welding wire reel body 1 is in normal use, one end of the welding wire is inserted into the slot 17 and then connected to the wire feeding device of the welding machine. When the electric welding machine is welding the metal parts, the wire feeding device works to feed the wire, and the rotating column 3 rotates following the wire feeding of the welding wire. Since the welding wire is regularly wound around the surface of the welding wire reel, the welding wire will squeeze the first semicircular block 7, causing the rotating rod 6 to retract and compress the first spring 10 connected to the surface of the first semicircular block 7, and the first spring 10 on the surface of the second semicircular block 8 will be reset, and then move the second semicircular block 8 toward the direction of the first semicircular block 7. At this time, the rotating rod 6 connected to the second semicircular block 8 extends out. When the welding wire squeezes the second semicircular block 8, the process is opposite to the above-mentioned step of the welding wire squeezing the first semicircular block 7. When the welding wire reel body 1 needs to be wound with welding wire, the rotating rod 6 is manually rotated The first semicircular block 7 is a kind of welding wire which is welded on the welding rod 6 and the second semicircular block 8 is a kind of welding wire which is welded on the welding rod 6 and the welding wire is welded on the welding rod 6.

[0030] Embodiment 2: During metal welding, the position of the welding gun head is movable, and the movement of the welding gun head will cause the position of the welding wire on the surface of the wire reel body 1 to change. When the welding gun head moves, in order to keep the welding wire on the winding route, the problem is solved by the following solution.

[0031] See also Figures 1 to 4The difference between the combined implementation basis is that a bracket 11 is fixedly connected to the surface of the first semicircular block 7, a guide rod 12 is fixedly installed on the surface of the bracket 11, a guide ring 13 is fixedly connected to one end of the guide rod 12, an annular groove 14 is provided inside the guide ring 13, an movable ring 15 is movably connected inside the annular groove 14, and a second spring 16 is elastically connected between the movable ring 15 and the annular groove 14. When the welding position of the metal part changes, the welding head corresponds to the welding position, and the welding head also needs to move. At this time, the bending angle of the welding wire changes, and the angle change of the welding wire will squeeze the movable ring 15, thereby causing the movable ring 15 to move toward the inside of the annular groove 14. At this time, the second spring 16 is compressed, and the change in the position of the welding head will not affect the change in the position of the welding wire on the surface of the welding wire reel body 1, thereby ensuring that the welding wire is always on the winding route, avoiding the dislocation of the welding wire, and thus ensuring the normal transportation of the welding wire.

[0032] One end of the second spring 16 is fixedly connected to the inner wall of the annular groove 14 , and the other end of the second spring 16 is fixedly connected to the surface of the movable ring 15 . The second spring 16 is used for the dynamic movement of the movable ring 15 .

[0033] The number of the second springs 16 is four.

[0034] The use steps of the utility model are as follows: when the new welding wire reel is in use, one end of the welding wire passes through the notch 17, and then passes into the guide ring 13, and then is connected to the wire feeding device. When the welding position of the metal part changes, the welding head corresponds to the welding position, and the welding head also needs to be moved. At this time, the bending angle of the welding wire changes, and the angle change of the welding wire will squeeze the movable ring 15, thereby causing the movable ring 15 to move toward the inside of the annular groove 14. At this time, the second spring 16 is compressed. The change in the position of the welding head will not affect the change in the position of the welding wire on the surface of the welding wire reel body 1, thereby ensuring that the welding wire is always on the winding route, avoiding dislocation of the welding wire, and thus ensuring the normal transportation of the welding wire.
