Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, and particularly relates to a steel pipe low-deformation cutting fixture. Background Art

[0002] In the current industrial production field, as a common and important material, steel pipes are widely used in many industries such as construction, mechanical manufacturing, petrochemical industry, etc. And the cutting process of steel pipes is a key link in their production and application.

[0003] In the process of cutting steel pipes, whether using sawing, flame cutting or laser cutting and other methods, vibrations and stresses will inevitably be generated. These vibrations and stresses will directly act on the steel pipes, resulting in deformation of the steel pipes at the cutting part and the surrounding areas. This deformation may be manifested in forms such as bending, twisting, diameter change, etc., thus seriously affecting the cutting accuracy.

[0004] Although the existing steel pipe cutting fixtures are designed to fix the steel pipes to reduce their movement during cutting, they often have poor effects in reducing deformation. Some common fixtures only fix the steel pipes through simple clamping devices. When the cutting tool contacts the steel pipe and applies a cutting force, the local part of the steel pipe will be strongly impacted and rubbed. Due to the rigidity of the steel pipe itself and the stress concentration generated during cutting, deformation often occurs at the cutting port, affecting the cutting accuracy and the quality of the finished product. Therefore, a steel pipe low-deformation cutting fixture is proposed. Summary of the Utility Model

[0033] In one embodiment, specifically: push buttons 44 are fixedly connected to the far ends of the two sliding rods 23, and the near ends of the two push buttons 44 are respectively attached to the far sides of the two support cylinders 25.

[0034] In one embodiment, specifically: support legs 45 are welded to the four corners of the lower surface of the cutting table 11.

[0035] When the utility model works: Place the thin-walled steel pipe 27 to be cut on the cutting table 11, and make it fit with the buffer anti-slip pad 31 in the arc-shaped groove 30 on the support seat 29 on the cutting table 11 to ensure that the steel pipe is stable and not easy to slide. Start the adjustment motor 19 to drive the positive and negative screw rod 20 to rotate. Since the threaded holes 21 on the two sliders 13 are threadedly connected with the positive and negative threads on both sides of the positive and negative screw rod 20, the two sliders 13 will move closer to each other along the sliding groove 12 as the positive and negative screw rod 20 rotates, thereby driving the fixed clamping blocks 14 and the movable clamping blocks 17 on both sides to move, so that both ends of the thin-walled steel pipe 27 are respectively inserted between the fixed clamping blocks 14 and the movable clamping blocks 17 on both sides, and continue to move to the position where the thin-walled steel pipe 27 needs to be clamped. Tighten the adjustment bolt 16 to limit the movable clamping block 17, thereby fixing the thin-walled steel pipe 27 between the fixed clamping block 14 and the movable clamping block 17, realizing the clamping and precise positioning of the steel pipe. Push the two push buttons 44 to drive the two slide rods 23 to move, thereby driving the support head 24 to insert into the thin-walled steel pipe 27 and slide along the thin-walled steel pipe 27 until the push button 44 and the support cylinder 25 are in contact. At this time, the two support heads 24 are slidably connected to both sides of the cutting blade 36, realizing the support of the inner sides of both sides of the cutting position of the thin-walled steel pipe 27 by the support heads 24. At the same time, the support seat 29 supports the outer sides of both sides of the cutting position of the thin-walled steel pipe 27, thereby reducing the deformation during the cutting process. Start the lifting motor 37, and the lifting motor 37 drives the gear 39 to rotate through the rotating shaft 38. Since the gear 39 meshes with the toothed plate 40 on the inner side of the lifting frame 34, the lifting frame 34 will slide downward along the connecting cylinder 33. At the same time, start the cutting machine 35, and the cutting blade 36 starts to rotate and cut the thin-walled steel pipe 27 downward. Since both sides of the steel pipe are clamped and the middle part is supported by the support heads 24 and the support seat 29, the deformation of the thin-walled steel pipe 27 during the cutting process is prevented, and the deformation of the cutting port part is greatly reduced.

[0036] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
