Description

Technical Field

[0001] This utility model belongs to the technical field of steel braided tube processing equipment, specifically a sandblasting device for roughening steel braided tubes. Background Technology

[0002] Rough-textured steel braided tubing refers to steel braided tubing with a rough surface formed by a specific process, such as pitting or unevenness, to enhance certain properties or meet specific usage requirements. It has strong wear resistance and corrosion resistance. In the fields of power, communication, and transportation, rough-textured steel braided tubing can be used to protect cables and wires from damage caused by external conditions.

[0003] When processing roughened steel braided tubing, appropriate sandblasting equipment is required to remove dirt, rust, scale, and other impurities from the surface of the tubing, while increasing surface roughness and improving coating adhesion. However, in actual use, there are still shortcomings. After sandblasting, dust and impurities will adhere to the outer surface of the steel braided tubing. When the tubing is removed, the dust and impurities on its outer surface will easily fall off and pollute the surrounding environment. Therefore, improvements are needed. Utility Model Content

[0021] 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.

[0022] like Figures 1 to 5As shown, this utility model provides a sandblasting device for roughening steel braided tubes, including a sandblasting box 1. A box door 2 is hinged to the left end of the sandblasting box 1. A crossbar 3 is fixedly sleeved on the right side inside the sandblasting box 1. A vertical block 4 is movably sleeved on the outer surface of the crossbar 3. An electric telescopic rod 5 is fixedly installed in the middle of the left end of the vertical block 4. A cleaning brush 6 is fixedly installed in the left end of the electric telescopic rod 5. The rear end of the cleaning brush 6 is movably connected to the rear inner wall of the sandblasting box 1. A short rod is fixedly installed in the middle of the right end of the vertical block 4. 7. The right end of the short rod 7 is movably connected to the inner wall of the right side of the sandblasting box 1. The top of the right side of the sandblasting box 1 is fixedly installed with a first motor 8. The other end of the output shaft of the first motor 8 is fixedly sleeved with a rotating shaft 9. The left end of the rotating shaft 9 passes through the sandblasting box 1 and extends into the interior of the sandblasting box 1 and is fixedly sleeved with a long rod 10. The right end of the long rod 10 is movably connected to the inner wall of the right side of the sandblasting box 1. A long groove 11 is opened inside the long rod 10. The bottom of the inner surface of the long groove 11 is movably sleeved with the outer surface of the short rod 7.

[0023] When the first motor 8 starts, the rotating shaft 9 will drive the long rod 10 to rotate. Since the long groove 11 and the short rod 7 are movably connected, the inner surface of the long groove 11 will exert a thrust on the outer surface of the short rod 7 under the action of the long rod 10, pushing the short rod 7 to move along the outer surface of the horizontal bar 3 with the vertical block 4. This causes the cleaning brush 6 and the electric telescopic rod 5 to move together with the vertical block 4. When the electric telescopic rod 5 starts, it will cause the cleaning brush 6 to move towards the steel braided tube, so that the outer surface of the steel braided tube can be cleaned by the cleaning brush 6.

[0024] The drive motor 12 is fixedly installed in the middle of the left end of the sandblasting box 1. The other end of the output shaft of the drive motor 12 is fixedly sleeved with the drive shaft 13. The right end of the drive shaft 13 passes through the sandblasting box 1 and extends into the interior of the sandblasting box 1, and is fixedly installed with the first clamping block 14.

[0025] When the drive motor 12 starts, the drive shaft 13 will cause the first clamping block 14 to rotate.

[0026] A pneumatic cylinder 15 is fixedly installed in the middle of the right end of the sandblasting box 1. The left end of the pneumatic cylinder 15 passes through the sandblasting box 1 and extends into the interior of the sandblasting box 1, and is movably sleeved with a second clamping block 16.

[0027] When the pneumatic cylinder 15 is activated, the second clamping block 16 will move toward the first clamping block 14, thereby cooperating with the first clamping block 14 to clamp and fix the steel braided tube.

[0028] The top right end of the sandblasting box 1 is fixedly equipped with a power motor 17. The other end of the output shaft of the power motor 17 is fixedly sleeved with a lead screw 18. The left end of the lead screw 18 passes through the sandblasting box 1 and extends to the left side of the sandblasting box 1. The left side of the outer surface of the lead screw 18 is threaded with a sandblasting gun 19. The sandblasting gun 19 is movably sleeved with a first limiting rod 20 located below the lead screw 18. The left and right ends of the first limiting rod 20 are fixedly connected to the inner walls of the left and right sides of the sandblasting box 1, respectively.

[0029] When the power motor 17 starts, it will cause the lead screw 18 to rotate, thereby causing the sandblasting gun 19, which is threadedly connected to the lead screw 18, to move along the outer surface of the first limit rod 20, thus completing the sandblasting operation.

[0030] Among them, the bottom of the inner walls on both sides of the sandblasting box 1 is movably connected to a movable rod 21, and a support block 22 is fixedly installed at the middle of the top of the movable rod 21.

[0031] When the movable rod 21 is pushed, it will move along the inner walls of the left and right sides of the sandblasting box 1, along with the support block 22.

[0032] The bottom right end of the sandblasting box 1 is fixedly installed with a second motor 23. The other end of the output shaft of the second motor 23 is fixedly sleeved with a threaded rod 24. The left end of the threaded rod 24 passes through the sandblasting box 1 and extends to the left side of the sandblasting box 1.

[0033] When the second motor 23 is started, the threaded rod 24 will rotate.

[0034] Among them, a movable block 25 is threadedly sleeved on the left side of the outer surface of the threaded rod 24, and a diagonal rod 26 is hinged to the top of the movable block 25. The other end of the diagonal rod 26 is hinged to the middle of the bottom end of the movable rod 21. A second limiting rod 27 is movably sleeved on the inner surface of the bottom end of the movable block 25. The left and right ends of the second limiting rod 27 are fixedly connected to the inner walls of the left and right sides of the sandblasting box 1, respectively.

[0035] When the threaded rod 24 rotates, the movable block 25, which is threadedly connected to the threaded rod 24, will move along the outer surface of the second limit rod 27 with the inclined rod 26, thereby causing the other end of the inclined rod 26 to generate a thrust on the movable rod 21, pushing the movable rod 21 to move.

[0036] Working principle and usage process of this utility model:

[0037] In use, the operator first places the steel braided tube to be processed in the groove at the top of the support block 22, and then starts the second motor 23, causing the threaded rod 24 to rotate. This causes the movable block 25, which is threaded onto the outer surface of the threaded rod 24, to move along the outer surface of the second limit rod 27 with the bottom end of the inclined rod 26. This causes the top end of the inclined rod 26 to generate a thrust on the movable rod 21, pushing the movable rod 21 and the support block 22 upward. When the steel braided tube is aligned with the first clamping block 14 and the second clamping block 16, the operator stops the second motor 23 and starts the pneumatic cylinder 15, causing the second clamping block 16 to move towards the first clamping block 14, thereby clamping and fixing the steel braided tube with the first clamping block 14. Then, the operator starts the drive motor 12, which allows the steel braided tube to rotate under the clamping and fixing of the first clamping block 14 and the second clamping block 16. This improves the convenience of aligning the steel braided tube with the first clamping block 14 and the second clamping block 16 with the support block 22, and realizes the automatic lifting and lowering of the steel braided tube.

[0038] The operator then starts the power motor 17, causing the lead screw 18 to rotate. This causes the sandblasting gun 19, which is threaded onto the outer surface of the lead screw 18, to move along the outer surface of the first limit rod 20, thus completing the sandblasting operation. After the sandblasting is completed, the operator starts the first motor 8, causing the rotating shaft 9 to drive the long rod 10 to rotate. This causes the inner wall of the long groove 11 to exert a thrust on the outer surface of the short rod 7, pushing the short rod 7, along with the vertical block 4, the electric telescopic rod 5, and the cleaning brush 6, to move along the outer surface of the horizontal rod 3. When the cleaning brush 6 is aligned with the steel braided tube, the electric telescopic rod 5 is activated again to ensure that the cleaning brush 6 and the steel braided tube are in contact, thereby cleaning the dust adhering to the outer surface of the steel braided tube.
