[0002] In the prior art, for example, a utility model with application number 202220159373.3 discloses a high-frequency straight seam welded pipe unit. In order to solve the problem that the interface of the tube blank is easily concave or protrudes too high during curling, affecting the subsequent joint of the tube blank and making it difficult to weld, the welding assembly is designed so that the weld of the plate in the rolled cylindrical state can be smoothed, and the warping phenomenon caused by the stress of the plate at the weld of the plate can be eliminated, thereby achieving an excellent straight seam welding effect, and further cooperating with the cylinder to realize the unloading operation of the welded plate, which is highly practical.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The welded pipe is continuously transported during the production process, but the above equipment cannot be processed continuously, which is inconvenient to use. In addition, the weld seam of the welded pipe is extruded and formed by up and down extrusion. The welded pipe is attached to the outside of the roller and slides along the length direction of the roller. If the weld seam is warped or concave, it will hinder the transportation of the welded pipe. At the same time, the welded pipe cannot be gathered, and the weld seam edge cannot be attached. In addition, the weld seam cannot be parallel attached, which affects the welding effect.

[0005] Therefore, a high-frequency straight seam welded pipe unit anti-deformation protection mechanism is designed to optimize the above problems. Utility Model Content

In addition, the side pressure wheels on both sides of the first shaped frame apply pressure to both sides of the welded pipe during transportation, and the weld is gathered and closed to facilitate welding operations, thereby improving the functionality of the device. A grinding mechanism consisting of a rotating roller, a sanding belt and a motor is arranged on the shaped frame, so that the side edges of the weld can be ground during the transportation of the welded pipe to ensure the tightness of the weld after closing, and the utility model is more practical.

Detailed Description of the Embodiment

[0022] To make the technical personnel in the technical field more clear and definite about the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0023] As Figure 1-Figure 4 shown, this embodiment provides a deformation prevention and protection mechanism for a high-frequency straight seam welded pipe unit, including a workbench 1 and a welding mechanism located on the top of the workbench 1. A first C-shaped frame 2 is fixed between the two sides of the top of the workbench 1. An upper pressing wheel 3 is rotatably installed on the inner top of the first C-shaped frame 2. Side pressing wheels 4 are rotatably installed on both sides inside the first C-shaped frame 2. A position adjusting mechanism for controlling the vertical movement of the upper pressing wheel 3 and the horizontal movement of the side pressing wheel 4 is provided on the side of the first C-shaped frame 2. A C-shaped frame 5 is fixed on the top of the side of the first C-shaped frame 2 facing the direction of the welded pipe entering. The thickness of the C-shaped frame 5 is less than the width of the weld. An inner pressing wheel 6 is rotatably installed at the bottom end of the C-shaped frame 5. The inner pressing wheel 6 is located below the upper pressing wheel 3. A grinding mechanism is provided at the middle position of the C-shaped frame 5.

[0024] Overall working principle: During the processing of welded pipes, they are horizontally conveyed from right to left along the length of the workbench 1. At this time, the welded pipes are extruded into shape and a weld seam with a certain width is reserved. The U-shaped frame 5 passes through the weld seam, and the inner pressure wheel 6 is located inside the welded pipe. When the welded pipe is conveyed, the grinding mechanism is used to grind and flatten the side of the weld seam. Then, the welded pipe passes between the upper pressure wheel 3 and the two groups of side pressure wheels 4. The two groups of side pressure wheels 4 are used to gather and fit the weld seam. During the fitting process, the upper pressure wheel 3 and the inner pressure wheel 6 are used to squeeze up and down to shape the weld seam. After shaping, the welded pipe is welded and formed by the welding mechanism.

[0025] In this embodiment, the welding mechanism includes a second U-shaped frame 10, a welding machine 11, and a welding torch 12. The second U-shaped frame 10 is fixed at the output end of the welded pipe on the top of the workbench 1. A welding machine 11 is installed on the top of the second U-shaped frame 10, and a welding torch 12 is installed on the inner top of the second U-shaped frame 10, and the welding torch 12 is aligned with the gap of the welded pipe.

[0026] Local working principle: After the weld seam of the welded pipe is fitted and passes through the inside of the second U-shaped frame 10, the welding machine 11 is started, and the welding torch 12 is used to automatically weld and form the weld seam.

[0027] In this embodiment, the position adjustment mechanism includes a rectangular sliding hole 13, a rectangular sliding rod 14, a bracket 15, and a screw 16. The rectangular sliding hole 13 is vertically opened on the inner side of the first U-shaped frame 2. Rectangular sliding rods 14 are slidably installed inside the rectangular sliding hole 13. Brackets 15 are fixed at the ends of the rectangular sliding rods 14. The side pressure wheels 4 and the upper pressure wheel 3 are respectively rotatably installed inside the brackets 15. Screws 16 are rotatably installed on the outer side of the first U-shaped frame 2, and one end of the screw 16 is threadedly connected to the rectangular sliding rod 14.

[0028] Local working principle: Since the diameters and thicknesses of the welded pipes are different, when extruding and shaping different welded pipes, the screw 16 is rotated to control the rectangular sliding rod 14 to slide inside the rectangular sliding hole 13, adjust the upper pressure wheel 3 up and down, and horizontally adjust the side pressure wheels 4 to adapt to welded pipes with different diameters and thicknesses.

[0029] In this embodiment, one end of the screw 16 away from the rectangular sliding rod 14 is fixed with an adjustment disc 17, and anti-slip lines are provided on the outer side of the adjustment disc 17.

[0030] Local working principle: During the process of rotating and adjusting the screw 16, the setting of the adjustment disc 17 can facilitate manual rotation control and make the operation more convenient.

[0031] In this embodiment, the grinding mechanism includes a rotating roller 7, a sand belt 8, and a motor 9. The rotating rollers 7 are symmetrically installed on the inner and outer sides of the U-shaped frame 5. A sand belt 8 is provided between the two groups of rotating rollers 7. A motor 9 is installed on the U-shaped frame 5, and the output end of the motor 9 is connected to the rotating roller 7.

[0032] Partial working principle: During the translation of the welded pipe, the weld is fitted with the outer side of the abrasive belt 8. At this time, the motor 9 is started to control the rotation of the abrasive belt 8 to grind the weld to make it smooth, so as to ensure the fitting effect of the weld.

[0033] In this embodiment, the diameter of the rotating roller 7 is greater than the thickness of the yoke 5, and the spacing between the outer edges of the abrasive belts 8 on both sides of the yoke 5 is the same as the spacing at the weld.

[0034] Partial working principle: During the grinding process, the inner side of the sanding belt 8 will not rub against the yoke 5, thus ensuring the service life of the sanding belt 8, and only the outer side of the sanding belt 8 is in contact with the weld for grinding.

[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
