Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe cutting, in particular to a protective device for an automatic steel pipe cutting machine. Background Art

[0002] Steel pipe cutting is a common metalworking process, widely used in oil pipelines, building structures, machinery manufacturing, and other fields. Traditional cutting methods include flame cutting, plasma cutting, laser cutting, and sawing, with different methods suitable for steel pipes of varying material, wall thickness, and precision requirements. With the advancement of automation technology, CNC cutting equipment has become increasingly popular, improving cutting efficiency and precision. However, high-speed cutting can still produce flying metal debris, hot slag, or broken pipe sections, posing safety risks.

[0003] After searching, a Chinese utility model patent with authorization announcement number CN221390085U was found, which discloses a billet cutting device for seamless steel pipe processing, comprising a pusher, a pipe body, an operating table, a cutter, a conveyor table, and a protective device. The pipe body is placed on the surface of the pusher, the operating table is fixedly connected to the surface of the pusher, the cutter is arranged on the surface of the operating table, the conveyor table is arranged at the end of the operating table away from the pusher, and the protective device is arranged on the surface of the operating table. The protective device includes a rotating rod that is rotatably connected to the surface of the operating table, a protective net is fixedly connected to the surface of the rotating rod, and the protective net is sleeved and connected to the surface of the cutter. The utility model, by providing a protective device, facilitates shielding and protecting the operating end of the cutter to prevent waste chips from splashing and causing injury to the operator, thereby effectively improving the safety of the equipment.

[0004] However, the above patent can only protect the waste chips generated by cutting. When the automatic cutting machine is cutting steel pipes, if the saw blade is stuck in the steel pipe, the saw teeth will act like a lever to violently lift the workpiece along the tangential direction of the saw blade's rotation, so that the cut steel pipe will quickly splash out and cause harm to nearby people. In view of this, the present application proposes a protective device for an automatic steel pipe cutting machine based on the above technical problems. Utility Model Content

A guide rod 19 is fixedly installed on the upper surface of the cast iron base 2;

[0034] If the steel pipe body 11 needs to be cut at an inclined angle, first loosen the bolt, and then rotate the positioning plate 10. The positioning plate 10 rotates around the center of the bolt under the restriction of the arc groove 18 and the guide rod 19, and the steel pipe body 11 is brought close to the rotated positioning plate 10. At this time, the threaded rod 13 is driven again to move a small distance, and the positioning block 9 also fits the rotated steel pipe body 11 and changes the angle, thereby fixing the rotated steel pipe body 11.

A brake block 28 is fixedly installed on one side of the mounting seat 3. When the cutting machine body 4 is working, the coil spring 27 twists. After the cutting is completed, the cutting machine body 4 returns to its initial position through the elastic force of the coil spring 27 and contacts the brake block 28. The brake block 28 prevents the cutting machine body 4 from rotating at too large an angle.

[0038] Reference Figure 1 、 Figure 7 Specifically: the frame 1 includes a C-shaped base 29, an L-shaped plate 30 is welded on the upper surface of the C-shaped base 29, a base 31 is welded between the L-shaped plates 30, a C-shaped slot 32 is provided on the base 31, and the cast iron base 2 is arranged in the C-shaped slot 32.

[0039] Working principle: When the cutting machine body 4 is used to cut the steel pipe body 11 and a material is stuck, the cut steel pipe body 11 will be quickly thrown out in the tangential direction of the saw blade rotation. The first frame body 5, the second frame body 6, and the third frame body 7 are used in combination to shield the rapidly moving steel pipe body 11. The wire mesh 8 can effectively reduce the impact force of the steel pipe body 11 when it is thrown out, thereby preventing the steel pipe body 11 from causing damage to surrounding personnel or equipment.

[0040] Place the steel pipe body 11 against the positioning plate 10, then rotate the rotating rod 14, which drives the threaded rod 13 to rotate. The positioning block 9 fixes the other side of the steel pipe body 11 under the push of the threaded rod 13, and then presses the cutter body 4 downward to cut the fixed steel pipe body 11. At this time, the coil spring 27 twists. After the cutting is completed, the elastic force of the coil spring 27 restores the cutter body 4 to its initial position and contacts the brake block 28. The brake block 28 prevents the cutter body 4 from rotating at an excessive angle.

[0041] When cutting the steel pipe body 11, the position of the moving block 21 on the C-shaped plate 20 can be pre-adjusted, and then the moving block 21 can be fixed to the C-shaped plate 20 with the locking screw 22, so that the length of each cut remains consistent. The length of the steel pipe body 11 after cutting can be clearly calculated through the linear scale mark 23;

[0042] If the steel pipe body 11 is to be cut at an inclined angle, first loosen the bolts, then rotate the positioning plate 10. The positioning plate 10 rotates around the center of the bolt under the restriction of the arc groove 18 and the guide rod 19, and the steel pipe body 11 is brought close to the rotated positioning plate 10. At this time, the threaded rod 13 is driven again to move a small distance, and the positioning block 9 also fits the rotated steel pipe body 11 and changes the angle, thereby fixing the rotated steel pipe body 11. The angle of the bevel cut by the steel pipe body 11 can be clearly known through the indicator arrow 25 and the angle scale mark 24.
