Technical Field
[0001] This utility model relates to the field of saw blade processing technology, specifically a stable feeding and welding tooth device for processing saw blades. Background Technology
[0002] A saw blade is a steel strip with serrations, the serrations being the main component, primarily used for cutting materials. While serrations meet traditional needs, such as cutting wood, current production activities also involve cutting metal. In these cases, a single serration is no longer sufficient. The mainstream solution is to weld a high-strength cutting head onto the serration, allowing the cutting head to cut the metal. However, this creates new problems: the cutting head is not a strictly regular shape, but rather a special shape with one triangular end and the other arc-shaped. Before welding, the cutting head needs to be fed to the serration, ensuring the arc-shaped end contacts the welding surface. High-precision welding places high demands on the stability of the feeding structure and the welding teeth. The cutting head must be fed at a precise angle without any positional shift during welding. Current technology lacks a welding tooth device that can simultaneously achieve stable and precise feeding and stable welding teeth. Therefore, how to simultaneously ensure stable and precise feeding of the specially shaped cutting head and stable welding has become an urgent problem for relevant technical personnel.

[0024] Furthermore, a motor 28 is fixedly mounted on the upper part of the rotating plate 4, and a screw 17 is fixedly mounted on the end of the output shaft of the motor 28. A first movable seat 25 is provided on the surface of the screw 17, and the first movable seat 25 is threadedly connected to the screw 17. A carrier 27 is fixedly mounted on the upper part of the first movable seat 25, and a mounting seat 24 is fixedly mounted on the upper part of the carrier 27. A first cylinder 26 is fixedly mounted on one end of the mounting seat 24 near the motor 28, and the output end of the first cylinder 26 passes through the mounting seat 24 and is fixedly connected to the second movable seat 23.
[0025] Furthermore, a first slide rail 19 is symmetrically fixed on the upper part of the rotating plate 4 and both sides of the screw 17. A first slider 20 is slidably mounted on the upper part of the first slide rail 19. The carrier 27 is fixedly connected to the first slider 20.

[0026] Furthermore, a rotating shaft 7 is provided at the lower end of the rotating plate 4 near the welding tooth part 2, and a fixed rail 5 is provided at the lower end of the rotating plate 4 away from the welding tooth part 2. A sliding rod 18 is vertically fixed at the upper part of the fixed rail 5, and a sliding groove 16 is vertically penetrating inside the rotating plate 4. The sliding groove 16 is slidably connected to the sliding rod 18.
[0027] Furthermore, a second cylinder 29 is fixedly installed on the upper part of the upper base 33, and a lifting plate 30 is fixedly installed at the output end of the second cylinder 29. An upper welding plate 31 is fixedly installed at the lower part of the lifting plate 30, and the upper welding plate 31 is located directly above the lower welding plate 32.

The third slider 35 is slidably connected to the third slide rail 36.
[0028] The working principle of this utility model for a stable feeding and welding tooth device for processing saw blades is as follows: After uniformly applying welding flux to the welding surface of the saw teeth, the saw blade is placed on the lower welding plate 32, with the welding surface of the saw teeth facing the feeding part 1. Under the sliding limit of the slide rod 18 on the slide groove 16, the rotating plate 4 is rotated to a suitable position, so that the limiting groove 37 at the end of the push plate 15 is directly facing the welding surface of the saw teeth. The controller 6 starts the vibratory plate 3, the motor 28, and the first cylinder 26. The continuous vibration of the vibratory plate 3 continuously conveys the internal cutting head to the straight track 11. The triangular end of the cutting head passes through the limiting groove 37 of the straight track 11 and the curved track 9 in sequence, and lands stably on the material plate 14. At this time, the triangular end of the cutting head points to the limiting groove 37 at the end of the push plate 15, and the arc-shaped end points to the welding surface of the saw teeth. The output end of the motor 28 drives the screw 17 to rotate. Under the sliding limit of the first slide rail 19 on the first slider 20, the screw 17 pushes the first moving seat 25 and the carrier 2 7 moves rapidly as a whole towards the welding tooth section 2 until the end of the stroke of the first moving seat 25. Under the sliding limit of the second slide rail 21 on the second slider 22, the output end of the first cylinder 26 pushes the second moving seat 23 towards the welding tooth section 2 until the end of the stroke of the second moving seat 23. During this process, the limiting groove 37 at the end of the push plate 15 limits one end of the triangular head until the head is pushed to the arc end and touches the welding surface of the saw teeth. The second cylinder 29 is activated. Under the sliding limit of the third slide rail 36 on the third slider 35, the output end of the second cylinder 29 pushes the lifting plate 30 down until the upper welding plate 31 presses against the saw blade. At this time, the upper welding plate 31 and the lower welding plate 32 stabilize and fix the saw blade and the head. The upper welding plate 31 and the lower welding plate 32 are turned on and held for a certain period of time to weld the head onto the welding surface of the saw teeth. The output end of the second cylinder 29 is reset and the saw blade is moved backward by one tooth position to start the next welding operation.

Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
