Technical Field
[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an automatic centering and straightening device for multi-roll synchronous cold-rolled steel pipes. Background Technology
[0002] In modern steel pipe production, multi-roll synchronous cold rolling technology is widely used. Multi-roll synchronous cold rolled steel pipe refers to steel pipe produced using multi-roll cold rolling technology. Multi-roll synchronous cold rolled steel pipe is produced by rolling steel pipe at a lower temperature through the cooperation of multiple cold rolling rolls. A straightening device is a device used to adjust and straighten the surface and shape of materials such as metal, plastic, and paper.
[0003] The automatic centering and straightening device for multi-roll synchronous cold-rolled steel pipes mainly consists of a support base, a cold rolling mill, and cold-rolled pipes. First, the steel pipe enters the cold rolling mill from the input end. Through the synchronous action of the multi-roll system, it is gradually compressed and straightened. During this process, the cold rolling mill ensures that the shape and size of the steel pipe meet the predetermined requirements by precisely controlling the pressure and speed. The support base is used to support the entire device and ensure stability and accuracy.
[0004] In the existing technology, some automatic centering and straightening devices for multi-roll synchronous cold-rolled steel pipes usually adopt a fixed centering method. When straightening steel pipes of different specifications and materials, they often cannot achieve effective positioning. The existing devices lack flexibility and cannot adapt to different diameters, resulting in poor straightening effect and reduced production efficiency. In order to address the above problems, an automatic centering and straightening device for multi-roll synchronous cold-rolled steel pipes is proposed. Utility Model Content

[0032] 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.
[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an automatic centering and straightening device for multi-roll synchronous cold-rolled steel pipes, including a support base 1. The support base 1 serves as the basic support structure for the entire automatic centering and straightening device, possessing sufficient strength and stability to bear various forces during the operation of the device. Collection support seats 6 are fixedly connected to both sides of the support base 1. A positioning mechanism is detachably connected to the collection support seats 6. The positioning mechanism includes two support base plates 7 and a push limit block 10. The bottom of the support base plates 7 is detachably connected to the top of the collection support seats 6. The collection support seats 6 not only provide an installation foundation for the positioning mechanism but also collect impurities and waste materials after the cold-rolled pipe 5 has been processed. A connecting support plate 8 is fixedly connected to the top of the collection support seats 6. A power component is fixedly connected to the top of the support base plates 7. The support base plates 7 can be flexibly adjusted on the collection support seats 6 according to actual production needs to adapt to the positioning requirements of cold-rolled pipes 5 of different specifications. The power component includes an electric telescopic column 9. When the electric telescopic column 9 is activated, it can accurately control the movement of the push limit block 10 in the vertical direction.
[0034] The bottom of the electric telescopic column 9 is fixedly connected to the top of the support base plate 7, and the output end of the electric telescopic column 9 is fixedly connected to the bottom of the push limit block 10. During operation, it can effectively limit and push the cold-rolled tube 5, ensuring the positional accuracy of the cold-rolled tube 5 during the straightening process. Two rotating rods 15 are rotatably connected to the inner side of the connecting support plate 8. The top of the rotating rods 15 is fixedly connected to the support limit seat 13. The inside of the support limit seat 13 is rotatably connected to the connecting fixed column 14, and the outside of the connecting fixed column 14 is fixedly connected to the connecting support cylinder 2. The rotating rods 15 and the support limit seat 13 are rotatably connected, realizing the adjustment of the steel pipe during the production process. The connecting fixed column 14, the connecting support column 12, and the connecting positioning block 11 provide support and accurate positioning for the cold-rolled tube 5. The external connection of the connecting support column 12 is fixedly connected to the connecting positioning block 11, and the internal connection of the rotating rod 15 is fixedly connected to the sliding column 17. The sliding column 17 is rotatably connected to the internal connection of the pushing limit block 10, so that the pushing limit block 10 can adjust the position of the steel pipe more flexibly, ensuring that the cold-rolled pipe 5 is always in the correct position throughout the rolling process. The external rotatable connection of the two sliding columns 17 is rotatably connected to the internal connection of the pushing limit block 10. When the pushing limit block 10 moves up and down under the action of the electric telescopic column 9, the rotatable connection between the sliding column 17 and the pushing limit block 10 can drive the rotating rod 15 to rotate around the rotatable connection between it and the connecting support plate 8, thereby realizing the positioning and adjustment of the cold-rolled pipe 5 by the connecting positioning block 11. The inner side of the support base 1 is fixedly connected to the cleaning mechanism.
[0035] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism includes two air pumps 16, which are activated inside the support base 1 to deliver the processed waste and impurities to the vicinity of the sliding assembly. The bottoms of the two air pumps 16 are fixedly connected to the inner side of the support base 1, and an air outlet pipe 24 is fixedly connected inside the air pumps 16. The sliding assembly is fixedly connected to the inner side of the support base 1, and the sliding assembly includes two drive slide rails 22 to facilitate periodic cleaning of the inside of the device throughout the rolling process, ensuring long-term high-speed operation of the equipment. The bottoms of the two drive slide rails 22 are fixedly connected to the top of the inner side of the support base 1, and a connecting block 21 is fixedly connected to the top of the two drive slide rails 22. The drive slide rail 22 drives the connecting block 21 to slide on the top of the support base 1, so that impurities and waste on the surface are collected into the collection support 6. The sponge 23 is fixedly connected inside the support base 1. The bottom of the connecting block 21 is slidably connected to the top of the inner side of the support base 1. The fixing plate 19 is fixedly connected to the top of the inner side of the support base 1. Multiple straightening columns 20 are fixedly connected to the outside of the fixing plate 19. The function of the straightening columns 20 is to maintain the appropriate geometry of the steel pipe during the rolling process by directly contacting the outside of the cold-rolled pipe 5, preventing bending and deviation. The sliding design of the straightening columns 20 also provides the necessary support force for the steel pipe.
[0036] A cold-rolled tube 5 is slidably connected to the inner side of the support base 1. The cold-rolled tube 5 is slidably connected to the inner side of the straightening column 20. The cold-rolled tube 5 is also slidably connected to the inner side of multiple connecting positioning blocks 11. Multiple connecting support cylinders 2 are fixedly connected to the top of the support base 1. A support connecting plate 3 is fixedly connected to the top of the multiple connecting support cylinders 2. A cold rolling mill 4 is fixedly connected to the bottom of the support connecting plate 3. The cold-rolled tube 5 is slidably connected to the inside of the cold rolling mill 4. The cold rolling mill 4 provides cold rolling pressure to the cold-rolled tube 5 so that the steel tube can achieve the required performance during the rolling process. The bottom of the cold-rolled tube 5 is slidably connected to the top of two connecting support plates 8. Two bolts 18 are threadedly connected to the inside of each support base plate 7. The bottom of the bolts 18 is threadedly connected to the top inside of the collecting support seat 6. The bolts 18 are used to connect the support base plate 7 and the collecting support seat 6 to ensure the stability of the structure, prevent loosening and vibration during the rolling process, and facilitate the positioning of the fixing mechanism.
[0037] Working principle: First, the cold-rolled tube 5 is supported by the base plate 7 and pushed upward by the electric telescopic column 9, which in turn pushes the limiting block 10 upward. The sliding column 17 slides inside the limiting block 10, thereby driving the two rotating rods 15 to slide outside the limiting block 10. At the same time, the two rotating rods 15 slide inward, thereby driving the connecting fixed column 14 to rotate inward. Simultaneously, the inner connecting fixed column 14 of the connecting support column 12 drives the connecting support column 12 and the connecting positioning block 11 to move inward. The two connecting positioning blocks 11 position the cold-rolled tube 5. When the cold rolling mill 4 is in use, the fixed plate 19 and the straightening column 20 cooperate to automatically straighten the tube. At the same time, the positioning mechanism positions the tube to prevent deviation. When the electric telescopic column 9 extends or retracts, the two connecting positioning blocks 11 release the cold-rolled tube 5, effectively preventing the cold-rolled tube 5 from deviating during the straightening process, improving production efficiency and quality, and enhancing stability.
[0038] Secondly, the system is started by the air pump 16, and the air output pipe 24 outputs air. When the air reaches the vicinity of the sliding component, the connecting block 21 is driven by the drive slide rail 22 to slide on the surface of the support base 1. This cleans the surface of the support base 1 of impurities and waste during processing. At the same time, the sponge 23 inside the support base 1 can absorb some of the noise during construction. Meanwhile, the bolt 18 separates the positioning mechanism from the collection support 6. The collection support 6 not only provides support for the positioning mechanism but also collects debris and waste. The collection support 6 not only provides support for the positioning mechanism but also effectively collects debris and waste generated during processing, ensuring the cleanliness of the work area and further improving the equipment and its service life.
[0039] 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.
