Description

Technical Field

[0001] This utility model relates to the field of flying saw technology in high-frequency straight seam welded pipe units, specifically to a flying saw guide rail for high-frequency straight seam welded pipe units. Background Technology

[0002] High-frequency straight seam welded steel pipe is a longitudinal welded steel pipe manufactured using high-frequency resistance welding technology. After the steel strip is rolled into a tubular shape, the skin effect and proximity effect generated by the high-frequency current heat the edges of the pipe to a molten state, and then the weld is formed by pressing with extrusion rollers. This product features a small heat-affected zone, high forming accuracy, and fast production efficiency. High-frequency straight seam welded pipe is processed through a production line.

[0003] In the straight seam welded pipe production line, the cooling water in the unit drips onto the linear guide rail when cutting the high-frequency straight seam welded pipe. If it is not cleaned in time, it will cause corrosion, oxidation and other damage to the linear guide rail of the cold cutting flying saw, resulting in rust on the surface of the linear guide rail. This will affect the smooth operation of the slider, damage the balls inside the slider, and reduce the service life of the linear guide rail. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A high-frequency straight seam welded pipe unit flying saw guide rail includes a guide rail 2, a slider 3, and a flying saw base 4. The slider 3 is slidably connected to the guide rail 2, and the flying saw base 4 is fixedly installed on the slider 3. It also includes a base plate 1. A pair of connecting arms 10 are rotatably connected to the slider 3. A traction plate 5 is provided below the pair of connecting arms 10. A sponge 6 is detachably connected to the bottom of the traction plate 5. The bottom surface of the sponge 6 contacts the top surface of the guide rail 2. Two swing arms 9 are rotatably connected to the traction plate 5. One end of each swing arm 9 is fixedly connected to a rotating shaft 12. The two rotating shafts 12 are rotatably connected to the two connecting arms 10 respectively. A traction component is connected between one of the rotating shafts 12 and the base plate 1.

[0025] Please see Figure 1 and Figure 2 The flying saw base 4 can slide on the guide rail 2 via the slider 3, so as to process the high-frequency straight seam welded pipe by the flying saw. During the translation process, the slider 3 can drive the rotating shaft 12 to rotate via the traction component. When the rotating shaft 12 rotates, it can drive one end of the swing arm 9 to rotate, thereby causing the other end of the swing arm 9 to revolve. At this time, the revolving end of the swing arm 9 can rotate at the bottom of the traction plate 5. Since the other end of the traction plate 5 is connected to another connecting arm 10 via another swing arm 9, but the movement trajectories of the two swing arms 9 are the same, the traction plate 5 can drive the sponge 6 to move along the extension direction of the guide rail 2 while wiping back and forth, thereby absorbing the cooling water dripping on the guide rail 2 through the sponge 6.

[0026] The traction assembly includes a rack 7 and a gear 8. The gear 8 is coaxially fixedly connected to one of the rotating shafts 12, and the rack 7 is horizontally fixedly mounted on the base plate 1 and meshes with the gear 8.

[0027] Please see Figure 2 and Figure 3 In this embodiment, the rack 7 is fixed on the base plate 1 and does not move, while the gear 8 can slide along the guide rail 2 with the slider 3 via the rotating shaft 12. The gear 8 is always engaged with the rack 7 during translation. Therefore, the gear 8 can rotate circumferentially during translation under the drive of the rack 7, thereby driving the rotating shaft 12 to rotate.

[0028] The slider 3 has a through hole 13, and a connecting shaft 16 is horizontally fixed between a pair of connecting arms 10. The connecting shaft 16 is coaxially rotatably connected in the through hole 13, and each connecting arm 10 is connected to the slider 3 with a locking component.

[0029] Please see Figure 3 and Figure 4 In order to facilitate the replacement of the sponge 6, in this embodiment, the connecting arm 10 is rotatably connected to the slider 3 and connected by a locking component. When the two connecting arms 10 are flipped upward, the locking component is unlocked. When the connecting arm 10 is rotated to a certain angle, the locking component is locked again, thereby fixing the current angle of the connecting arm 10 so as to facilitate the replacement of the sponge 6.

[0030] The locking assembly includes a first locking hole 14, a second locking hole 15, and a locking block 17. The locking block 17 is horizontally and elastically connected to the connecting arm 10. The first locking hole 14 and the second locking hole 15 are both opened on the slider 3. The spherical end of the locking block 17 is located inside the first locking hole 14. A cavity communicating with the outside is opened inside the connecting arm 10. The locking block 17 is horizontally slidably connected inside the cavity. A spring 18 is fixedly connected between the locking block 17 and the cavity.

[0031] Please see Figure 4 When the connecting arm 10 rotates about the connecting shaft 16, the connecting arm 10 can drive the locking block 17 to rotate synchronously. At this time, the locking block 17 is subjected to a radial force along the first locking hole 14 inside the first locking hole 14. Therefore, the locking block 17 will disengage from the inside of the first locking hole 14. Since the locking block 17 is spherical inside the first locking hole 14, when the locking block 17 disengages from the inside of the first locking hole 14, the locking block 17 as a whole can move towards the inside of the cavity and compress the spring 18. As the connecting arm 10 rotates, when the connecting arm 10 rotates to an angle that is convenient for replacing the sponge 6, the locking block 17 enters the second locking hole 15 under the elastic force of the spring 18. At this time, the connecting arm 10 remains stationary, thereby realizing the relocking of the connecting arm 10, so as to facilitate the replacement of the sponge 6.

[0032] A smooth section 11 is provided on the rack 7, and the smooth section 11 is located at one end of the rack 7.

[0033] Please see Figure 2 Since the connecting arm 10 will drive the gear 8 to rotate synchronously when it is flipped, in order to prevent interference between the gear 8 and the rack 7, a smooth section 11 is provided on the rack 7 in this embodiment. When flipping the connecting arm 10, the gear 8 needs to be moved to the smooth section 11 of the rack 7 to prevent interference between the gear 8 and the teeth of the rack 7.

[0034] A pair of limiting parts 19 are symmetrically fixedly installed on the bottom of the traction plate 5. The two sides of the sponge 6 are in contact with the two limiting parts 19 respectively, and the top surface of the sponge 6 is in contact with the bottom surface of the traction plate 5.

[0035] Please see Figure 5 The two limiting parts 19 can limit the sponge 6 from both sides, and the sponge 6 can be pressed between the guide rail 2 and the traction plate 5 under the action of gravity. When the sponge 6 is replaced, the sponge 6 can be directly removed after flipping the connecting arm 10.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
