Description

Technical Field

[0001] This utility model belongs to the field of high-frequency welded pipe technology, and specifically relates to a high-frequency welded pipe processing device. Background Technology

[0002] The processing of high-frequency welded pipes mainly involves strip uncoiling, leveling, forming, high-frequency welding, sizing, and flying saw cutting. High-frequency welding achieves strip fusion through resistance heating, and the pipes are finally cut into fixed-length finished products by flying saw. However, some processes are relatively crude, and the chamfering step is often omitted after cutting, resulting in a large number of burrs and sharp edges on the ends of the welded pipes due to the high temperature of welding and tool wear.

[0003] These untreated burrs and sharp edges pose multiple risks: they can easily scratch operators, affect the precision of pipe fitting connections leading to poor sealing, and exacerbate pipe wear during fluid transport. Integrating cutting and chamfering allows for immediate burr removal after cutting, reducing process transfers and manual intervention, and significantly improving efficiency. Therefore, developing an integrated device that combines customized cutting and efficient chamfering functions is key to optimizing the processing flow. Utility Model Content

The mounting sleeve has a guide groove extending in the radial direction, and the turntable has an arc-shaped pushing groove. The two ends of the pushing groove are close to the center and the circumference of the turntable, respectively.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] refer to Figures 1 to 4 The high-frequency welded pipe processing device described in this embodiment includes a mounting plate 1, on which a segmented expansion shaft 2 for fixing the welded pipe is mounted. A cutter 5 is mounted above the welded pipe, and a chamfering assembly 4 is also mounted on the mounting plate 1. The produced high-frequency welded pipe is slowly moved out from the previous process. The segmented expansion shaft 2 is inserted into the welded pipe to fix it. At the same time, the chamfering assembly 4 chamfers the cross-section of the welded pipe, grinding away burrs and sharp edges. Then, the cutter 5 cuts the welded pipe at a suitable position.

[0026] The chamfering assembly 4 includes a roller guide rail 41 and a chamfering blade 42. The chamfering blade 42 is mounted on the output end of the roller guide rail 41. The chamfering blade 42 grinds the edge of the welded pipe in a circular motion under the drive of the roller guide rail 41.

[0027] The roller guide rail 41 includes a guide rail 411, a mounting plate 412, and a roller 413. The guide rail 411 is circular and coincides with the axis of the welded pipe. The roller 413 moves along the guide rail 411 and is mounted on the mounting plate 412. The chamfering knife 42 is mounted on the mounting plate 412 and its grinding end abuts against the edge of the welded pipe. The chamfering knife 42 rotates along the guide rail 411 under the drive of the mounting plate 412, thereby grinding the edge of the welded pipe.

[0028] Preferably, the segmented expansion shaft 2 includes a first motor 21, segments 24, and a pushing assembly mounted on the mounting plate 1. The pushing assembly is mounted on the output end of the first motor 21 and includes a mounting sleeve 22 and a turntable 26. The mounting sleeve 22 is mounted on the mounting plate 1. The output shaft of the first motor 21 passes through the mounting plate 1 and is inserted into the mounting sleeve 22 and fixedly connected to the turntable 26. The inner wall of the mounting sleeve 22 and the outer wall of the turntable 26 are rotatably connected. The axis of the turntable 26 coincides with that of the mounting sleeve 22. The mounting sleeve 22 has multiple sets of radially oriented... The extended guide groove 23 has multiple sets of arc-shaped push grooves 27 on the turntable 26. The two ends of the push groove 27 are close to the center and the circumference of the turntable 26, respectively. A support rod 25 is installed inside the segment 24 and extends into the mounting sleeve 22. A connecting rod 28 is slidably installed between the guide groove 23 and the push groove 27. The connecting rod 28 is hinged to the support rod 25. The length direction of the support rod 25 is consistent with the extension direction of the guide groove 23. The push groove 27, the guide groove 23, the support rod 25, the connecting rod 28 and the segment 24 correspond one-to-one.

[0029] The first motor 21 starts and drives the turntable 26 to rotate. The turntable 26 drives multiple sets of push grooves 27 to rotate. The push grooves 27 push the connecting rod 28 along the guide groove 23 to move closer to or away from the axis, thereby driving the support rod 25 to move closer to or away from the axis, thereby pushing the segment 24 closer to or away from the axis. The segment 24 moves away from the axis and abuts against the inner wall of the welded pipe to fix the welded pipe.

[0030] It also includes a movable component 3 to help change the movement of the mounting plate 1, thereby cutting welded pipes of different lengths. The movable component 3 is located below the welded pipe and extends along the length of the welded pipe. The mounting plate 1 is mounted on the output end of the movable component 3.

[0031] The moving component 3 includes a ball screw drive device 31 and a slide rail 32. The ball screw drive device 31 includes a ball screw 313, a second motor 311 and a base 312. The ball screw 313 is rotatably mounted in the base 312 and one end passes through the base 312 and is mounted on the second motor 311. The ball screw 313 is aligned along the length of the welded pipe. The mounting plate 1 is mounted on the moving end of the ball screw 313. The slide rail 32 is mounted on both sides of the base 312 and is slidably connected to the mounting plate 1 and the slide rail 32.

[0032] Preferably, a support block 6 is installed near the processing end of the welded pipe in the moving component 3 to support one end of the welded pipe, and the support block 6 slides relative to the bottom end of the welded pipe.

[0033] Working principle: The welded pipe moves from the previous process to the support block 6. The moving component 3 drives the mounting plate 1 to move to one side of the welded pipe. The split expansion shaft 2 is inserted into the welded pipe. Then the first motor 21 starts, driving the split 24 to extend outward to abut against the inner wall of the welded pipe, thereby fixing the welded pipe. The second motor 311 and the roller guide rail 41 start at the same time. The second motor 311 drives the ball screw 313 to rotate, thereby driving the mounting plate 1 to move synchronously with the welded pipe. At the same time, the chamfering knife 42 chamfers and grinds the end of the welded pipe to remove burrs.

[0034] This device uses a segmented expansion shaft 2 to internally tighten and fix the tube, providing strong and uniform support and effectively preventing deformation of thin-walled tubes during processing. It integrates the traditional two separate processes of cutting and chamfering into one station and completes them in a single clamping operation. This eliminates intermediate handling, secondary positioning, and clamping time, significantly improving production efficiency. It also simplifies the production process, reduces equipment requirements and floor space, and is easier to integrate into automated production lines, achieving full automation from material loading to processing completion, reducing manual intervention and operational risks.
