Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing, and in particular to a guide and collection cover for cutting debris from steel pipes. Background Technology

[0002] In the field of steel pipe processing, cutting is a fundamental and frequently used process, widely applied in various industries such as construction, machinery manufacturing, and pipeline engineering. While these traditional cutting equipment can meet basic cutting needs over long-term use, they have significant shortcomings in terms of slag protection and collection.

[0003] Traditional cutting equipment generally lacks a dedicated protective cover. During cutting operations, the high-speed rotating cutting tool violently rubs and collides with the steel pipe material, generating a large amount of high-temperature flying debris. This debris often flies around in an irregular manner, which can not only cause burns and cuts to the operators, but also affect the normal operation and service life of the equipment. Even if some cutting equipment is equipped with protective devices, these devices are usually simple in structure and can only shield a small part of the cutting area, failing to completely block the path of flying debris. Utility Model Content

[0017] 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.

[0018] Reference Figures 1-4This utility model provides an embodiment of a steel pipe cutting debris guide and collection cover, comprising a base 1; a main cutting chamber cover 4, which is mounted on the base 1; a first T-shaped slot 21, which is formed on the inner sides of the left and right ends of the main cutting chamber cover 4; a secondary cutting chamber cover 5, which is disposed inside the main cutting chamber cover 4, and a protective grille 8 is fixedly connected to the lower end of the secondary cutting chamber cover 5; and T-shaped strips 20, which are disposed on the outer sides of the left and right ends of the secondary cutting chamber cover 5, and the T-shaped strips 20 are slidably connected. The system includes: a first T-shaped slot 21; a stop block 10, mounted on the base 1 and positioned between the main cutting chamber cover 4 and the secondary cutting chamber cover 5; a protective cover 9, mounted on the stop block 10, with a cutting wheel 19 inside; a protective cover 11, positioned on top of the main cutting chamber cover 4, with a drive assembly inside its rear end for driving the cutting wheel 19; and a collection box 2, located inside the base 1 for collecting steel pipe cutting debris. A handle 3 is fixedly connected to the front end of the collection box 2. The drive assembly includes a fixed plate 12 fixedly connected to the rear end of the protective cover 11. A motor 13 is fixedly connected to the inner wall of the fixed plate 12. A first bevel gear 14 is fixedly connected to the drive end of the motor 13. A rotating shaft 17 is fixedly connected to the middle of the cutting wheel 19. Limiting blocks 16 are rotatably connected to the left and right ends of the rotating shaft 17. The opposite sides of the limiting blocks 16 are fixedly connected to the outside of the protective cover 9. A second bevel gear 15 is fixedly connected to one end of the rotating shaft 17. Wheel 15 meshes with the first bevel gear 14. The upper rear end of the secondary cutting chamber cover 5 is fixedly connected to a scraper 18 inside the main cutting chamber cover 4. The upper side of the scraper 18 is in close contact with the inner wall of the main cutting chamber cover 4. The lower ends of the left and right sides of the secondary cutting chamber cover 5 are provided with second T-shaped slots 22. The inner wall of the second T-shaped slot 22 is slidably connected to a push-pull rod 6. The rear end of the push-pull rod 6 is fixedly connected to a U-shaped frame 7. The front end of the U-shaped frame 7 is fixedly connected to the rear end of the protective grille 8. The front end of the protective grille 8 is fixedly connected to the secondary cutting chamber cover 5.

[0019] The steel pipe to be cut is placed in the cutting position of the U-shaped frame 7 through the opening between the secondary cutting chamber cover 5 and the main cutting chamber cover 4. The base 1 and the U-shaped frame 7 provide limiting support for the steel pipe, ensuring the stability of the steel pipe position during cutting. The main cutting chamber cover 4 and the secondary cutting chamber cover 5 are slidably engaged through the T-shaped strip 20 and the first T-shaped slot 21, which can flexibly adjust the opening and closing state. This facilitates the loading and unloading of the steel pipe to be cut and forms a relatively closed working space during cutting, effectively limiting the spread of flying chips and reducing pollution to the surrounding environment. The protective cover 11 provides protection for the internal drive components to prevent personnel from accidentally touching the operating parts. The fixing plate 12 securely fixes the motor 13 to ensure the stable operation of the motor 13. The limiting block 16 limits the rotation shaft 17, reducing the radial runout when the cutting wheel 19 and the protective cover 9 rotate, ensuring the cutting wheel 19 cuts smoothly and improving the flatness of the steel pipe cut. The protective cover 9 is straight. The cover 10 further blocks the flying debris from splashing outwards, reducing the risk of personnel being scratched by flying debris. The baffle 10 can block the flying debris that splashes forward during cutting, supplementing the blind spot of the secondary cutting chamber cover 5. The scraper 18 at the rear end of the secondary cutting chamber cover 5 is in close contact with the inner wall of the main cutting chamber cover 4. When the secondary cutting chamber cover 5 slides, it can scrape off the flying debris attached to the inner wall of the main cutting chamber cover 4, preventing the accumulation of flying debris. A T-shaped protrusion is provided on the opposite side of the push-pull rod 6. It is slidably connected to the secondary cutting chamber cover 5 through the second T-shaped slot 22. Pushing the push-pull rod 6 can drive the U-shaped frame 7 and the protective grille 8 to move. The foldable protective grille 8 can adapt to the back and forth movement of the push-pull rod 6 and unfold accordingly. During cutting, it can also prevent sparks and flying debris from flying out of the steel pipe insertion port. The handle 3 at the front end of the collection box 2 makes it easy for the operator to pull out the collection box 2 and quickly clean the flying debris collected inside, reducing the amount of cleaning work.

[0020] Working principle: By pulling out the collection box 2 through handle 3, adding a certain amount of water to the collection box 2, and pushing the collection box 2 back into the base 1, the push rod 6 is pulled outwards. The steel pipe to be cut is placed into the U-shaped frame 7 through the opening on one side of the main cutting chamber cover 4 and the secondary cutting chamber cover 5. The motor 13 is started, and the push rod 6 is pushed inwards. The push rod 6 slides inwards along the second T-shaped slot 22 with the T-shaped protrusion set on the inner side. The protective grille 8 unfolds accordingly. The drive shaft of the motor 13 drives the first bevel gear 14 to rotate. The first bevel gear 14 drives the second bevel gear 15. The second bevel gear 15 drives the rotating shaft 17 and the cutting wheel 19 to rotate and cut the steel pipe. During cutting, the flying debris generated is confined by the space enclosed by the protective outer cover 9, the main cutting cavity cover 4, the secondary cutting cavity cover 5, the protective grid 8, and the stop block 10. The sparks and flying debris generated during cutting fall into the water inside the collection box 2. When cleaning is required, push the push-pull rod 6 upward. The push-pull rod 6 drives the secondary cutting cavity cover 5 and the T-shaped strip 20 to slide along the second T-shaped slot 22. During the sliding process, the scraper 18 at the tail end of the secondary cutting cavity cover 5 scrapes off the flying debris that was sprayed on the inner wall of the main cutting cavity cover 4 during the cutting process. The flying debris falls into the water inside the collection box 2. Pull out the collection box 2, clean the collected flying debris, and then put the collection box 2 back into the base 1.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
