[0015] 1. The arc-shaped side wall and the straight upper end wall of the shaping plate of the present invention can both be used to contact the end wall of the steel pipe to shape the steel pipe fitting. When in use, two connecting blocks are arranged at the end wall of the shaping plate. One connecting block on the left is inserted into the transmission rod and then positioned by inserting a screw, so that the arc-shaped side wall of the shaping plate fits the steel pipe for shaping.

[0018] 4. Steel pipe fittings can be respectively inserted and placed in the two material passing openings of the fixed penetration seat of the present invention to detect the straightness of the welded steel pipe for shaping. When a steel pipe fitting is inserted into one of the material passing openings, the steel pipe contacts the end wall of the horizontal measuring ruler. The horizontal measuring ruler moves sideways for a certain distance, and then the steel pipe rotates. Observe whether the horizontal measuring ruler moves sideways again and observe and read the parameters after the horizontal measuring ruler moves horizontally to simply understand the straightness of the steel pipe fitting.

[0032] In summary, when the welding steel pipe shaping device for the crawler crane tower is in use,

[0033] One end of the steel pipe is inserted into the three-jaw clamp at 27 and clamped and positioned. Then, the upper motor 26 operates to drive the three-jaw clamp 27 to rotate, so that the steel pipe part rotates, facilitating subsequent contact shaping with the shaping part structure;

[0034] During shaping, two oppositely arranged cylinders 5 operate to drive the transmission rod 6 to displace, so that the end wall of the shaping plate 7 is attached to the end wall of the steel pipe clamped by the three-jaw clamp 27. The steel pipe rotates, and the end wall contacts the end wall of the shaping plate 7 for shaping and correction;

[0035] Among them, both the arc-shaped side wall and the straight upper end wall of the shaping plate 7 can be used to contact the end wall of the steel pipe to shape the steel pipe part. When in use, two connecting blocks 8 are arranged at the end wall of the shaping plate 7. One connecting block 8 on the left is inserted into the transmission rod 6 and then positioned by passing through a screw 10, so that the arc-shaped side wall of the shaping plate 7 fits the steel pipe for shaping use;

[0036] One connecting block 8 at the lower side of the shaping plate 7 is inserted into the transmission rod 6 and then positioned by passing through a screw 10, so that the straight upper wall of the shaping plate 7 fits the steel pipe for shaping use. During shaping use, the two shaping methods can be switched conveniently without arranging multiple shaping plates, and the shaping structure is less and more compact;

[0037] The lower motor 11 operates to drive the screw rod rotatably connected to the bottom plate 1, and the transmission slide seat 3 moves along the axis direction of the screw rod, so that the two slide seats 3 move towards or away from each other. Furthermore, the four shaping plates 7 in two pairs can adjust their positions to shape and correct different position nodes of the steel pipe part, which is more flexible and convenient during use. At the same time, the slide rail groove 24 at the bottom of the slide seat 3 is movable with the slide rail part 2 and displaces along the length direction of the slide rail 2, making the displacement of the slide seat 3 more stable;

[0038] A material storage seat 14 is movably connected in the chute opening 12 of the slide seat 3. When the material storage seat 14 moves upward, the top end wall, the middle seat 19 and the middle opening 18 of the material storage seat 14 are all exposed. At this time, the welded pipe parts can be placed on the top end wall of the material storage seat 14, the upper end wall of the middle seat 19 and the bottom end wall of the top opening 4 of the slide seat 3 for temporary storage, improving the storage performance of the entire shaping structure;

[0039] Among them, the screw 13 is tightened, and the end of the screw 13 contacts the end wall of the middle area of the material storage seat 14 to lock and limit the material storage seat 14. The upper cotton block 17, the seat cotton block 21 and the lower cotton block 23 are all made of sponge material and have buffering properties, which are used to buffer and protect the placed welded steel pipe parts and can absorb the liquid on the steel pipe parts;

[0040] An edge through - opening 29 of the side seat 28 is provided with and fixedly connected to a fixed - through seat 30, so that the edge through - opening 29 located below the fixed - through seat 30 can facilitate the passing of the end of a longer welded pipe stored in the shaping structure, and facilitate the flat placement of the longer steel pipe.

[0041] Steel pipe parts can be respectively inserted and placed in the two material - passing openings 32 of the fixed - through seat 30 for detecting the straightness of the shaped welded pipe. When a steel pipe part is inserted into one of the material - passing openings 32, the steel pipe contacts the end wall of the horizontal measuring scale 33. The horizontal measuring scale 33 moves laterally by a certain distance. Then the steel pipe rotates, and it is observed whether the horizontal measuring scale 33 moves laterally again, and the parameters after the translation of the horizontal measuring scale 33 are observed and read to simply understand the straightness of the steel pipe part.

[0042] The above - mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
