Technical Field

[0001] The utility model relates to the technical field of welded pipe processing, in particular to a feeding and discharging mechanism of a welded pipe seaming machine. Background Art

[0002] Welded steel pipe, also known as welded pipe, is made by welding steel plates or strips that have been coiled and formed. Its production process is simple, efficient, and offers a wide variety of specifications with minimal equipment investment. Its strength is lower than that of seamless steel pipe, making it widely used in industry. In existing technology, unseamed pipes are typically transported using a driven guide wheel assembly, which is then clamped and fed into a seaming machine for welding. However, due to varying degrees of torsion or deformation in the pipes and the point-contact connection between the driving guide wheel assembly and the pipe, the seam often deviates during transport, resulting in loose welds and compromised weld quality.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1-5 As shown, a feeding and discharging mechanism of a pipe welding machine includes a frame 1, 6 groups of guide wheels, a clamping assembly and a transverse movement mechanism. The guide wheels 6 groups have two rows and are symmetrically installed on the frame 1. The transverse movement mechanism is installed on the frame 1 between the two rows of guide wheels 6 groups. The clamping assembly is installed at the upper end of the output end of the transverse movement mechanism, and the clamping assembly can move transversely between the two rows of guide wheels 6 groups. The unseamed pipe 11 is mounted on the two rows of guide wheels 6 groups, and the clamping assembly clamps and fixes the pipe wall. Under the drive of the transverse movement mechanism, the clamping assembly pushes and pulls the pipe 11 for transverse movement, and cooperates with the seaming machine to weld and close the pipe seam 1101. During this process, the clamping assembly and the two rows of guide wheels 6 groups do not interfere with each other, ensuring that the pipe 11 passes completely through the seaming machine from head to tail.

[0022] In the above embodiment, the guide wheel group 6 includes multiple support plates 5 and multiple guide wheels 6. The multiple support plates 5 are respectively mounted on the frame 1, and the multiple guide wheels 6 are respectively rotatably connected to the side surfaces of the multiple support plates 5. In this structure, one end of the guide wheel 6 is suspended in the air, while the corresponding guide wheels 6 in the two rows of guide wheel groups 6 jointly support the pipe 11 without affecting the lateral movement of the clamping assembly. The guide wheels 6 are conical, and a recessed area is formed between the corresponding conical guide wheels 6 in the two rows of guide wheel groups 6. When the pipe 11 is not clamped, it can naturally sink between the two rows of guide wheels 6 and be supported, facilitating the positioning and clamping of the pipe 11, and ensuring the straightness of the pipe 11 during lateral movement, thereby ensuring the quality of the weld.

[0023] The transverse movement mechanism includes a motor 2, a screw rod 4, and a sliding plate 7. The frame 1 is provided with two supports 3, one in front and one in the back. The screw rod 4 is rotatably connected between the two supports 3, passes through and is transmission-connected to the sliding plate 7, and the lower end of the sliding plate 7 is slidably connected to the frame 1. The motor 2 is mounted on the side of the frame 1, and the output end of the motor 2 is connected to the screw rod 4. The clamping assembly is mounted on the upper end of the sliding plate 7. Driven by the motor 2, the screw rod 4 rotates and drives the sliding plate 7 to slide transversely along the frame 1, thereby driving the clamping assembly on the sliding plate 7 to transversely transport the pipe 11. The frame 1 is provided with a guide rail, and the lower end of the sliding plate 7 is provided with a guide groove. The guide rail and the guide groove are slidably connected, reducing the friction between the sliding plate 7 and the frame 1, making the sliding plate 7 move transversely more smoothly.

[0024] The clamping assembly includes a frame 8, a splint 9 and a spring 10. The frame 8 is installed on the upper end of the sliding plate 7. The frame 8 is U-shaped and the opening is facing the side. Two guide columns 801 are provided at the upper and lower ends of the frame 8. Two guide cylinders 901 are provided on the splint 9. The two guide cylinders 901 are respectively slidably connected to the two guide columns 801. The spring 10 is sleeved on the guide cylinder 901. The spring 10 is located between the frame 8 and the splint 9. There are two splints 9 and they are arranged facing each other. The pipe 11 is mounted on the upper end of the two rows of guide wheels 6. The lower side pipe wall is embedded between the two splints 9. Under the action of 10, the pipe 11 is clamped vertically. When the transverse movement mechanism pushes and pulls the clamping assembly, the spring 10 provides positive pressure on the surface of the pipe 11 for the clamping plate 9, so that there is a high static friction between the two clamping plates 9 and the pipe 11, preventing slippage between the two when the clamping assembly pushes and pulls the pipe 11, ensuring that the pipe 11 moves horizontally smoothly; the clamping plate 9 and the spring 10 can be connected to the frame 8 by an assembled method, which is convenient for disassembly and assembly, and is also convenient for clamping and fixing the pipe 11. After the pipe 11 is erected and positioned, the spring 10 and the clamping plate 9 are inserted to fix it.

[0025] In addition, the spring 10 is connected to the frame 8 and the clamping plate 9 by welding, preventing the two clamping plates 9 from falling out. When loading and unloading the pipe 11, only the clamping plates 9 need to be loosened, which is convenient and quick. The facing surfaces of the two clamping plates 9 are provided with rubber material 902, which further increases the static friction between the two clamping plates 9 and the pipe 11.

[0026] Description of the working method of this utility model:

[0027] The frame 1 of the device is placed across the gantry of the seaming machine. Unseamed pipes 11 are stacked at the diagonal positions on both sides of the gantry. When seaming is performed, the pipes 11 are alternately operated on the left and right sides. The specific operation is as follows: loading is performed on the left side of the seaming machine, and the pipes 11 are placed on two rows of guide wheels 6. After adjusting the pipe seam 1101 to face up, the two clamps 9 are pulled apart, and the pipe wall on the lower side of the pipe 11 is pushed between the two clamps 9. After releasing the clamps 9, the pipe 11 is clamped. After visually checking that the pipe 11 has no deviation, the motor 2 can be started to transport the pipe 11 horizontally. When the pipe 11 approaches the welding head and triggers the position sensor of the seaming machine, the welding head starts welding. The welding head stops welding after the pipe 11 completely passes the welding head and triggers another position sensor. The welded pipe 11 is removed and a new unwelded pipe 11 is reloaded, and feeding and welding are performed from right to left to complete a reciprocating welding work stroke, thereby ensuring the continuous progress of the welding work and improving the welding efficiency.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
