Seamless steel pipes can be divided into two categories: general-purpose and special-purpose. General-purpose seamless steel pipes are rolled from ordinary carbon structural steel, low-alloy structural steel, or alloy structural steel, and are mainly used as pipelines for transporting fluids or as structural components. Special-purpose seamless steel pipes include various types such as seamless pipes for boilers, seamless pipes for chemical and power industries, seamless steel pipes for geological applications, and seamless steel pipes for petroleum applications. During the production of seamless steel pipes, straight steel pipes are generally produced first, and then bent into various shapes according to production needs to suit different applications.

[0003] During the bending process, the mechanism and the steel pipe are in hard contact. As the steel pipe gradually bends, it wobbles and rebounds when the mechanism separates from the pipe, requiring manual support to stabilize it. This can easily lead to injury to the operator. Furthermore, the bending process generates a large amount of dust and impurities, which pollute the environment and affect the health of those around them. To address these issues, the inventor proposes a seamless steel pipe bending and forming device. Utility Model Content

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.

[0021] Example: Figure 1-4 As shown, this utility model provides a technical solution: a seamless steel pipe bending and forming device, including a base plate 1, a U-plate 2 fixedly connected to the center of the back end of the base plate 1, a top plate 21 fixedly connected to the front end of the U-plate 2 and near the top, a protective cover 22 slidably inserted inside the top plate 21, and the protective cover 22 being located at the center above the base plate 1, a limiting block 3 symmetrically fixedly connected to the top end of the base plate 1 near the center, a limiting plate 31 slidably inserted at the front end of the limiting block 3, a slider 36 symmetrically slidably connected to the top end of the base plate 1 and near the limiting plate 31, a limiting wheel 37 fixedly connected to one end of the slider 36 near the limiting plate 31, and a limiting block 4 slidably connected to the top end of the base plate 1 and between the two limiting blocks 3.

[0022] A second vertical plate 42 is fixedly connected to the top of the substrate 1 and near the second limiting block 4, and a first vertical plate 39 is fixedly connected to the top of the substrate 1 and near the slider 36.

[0023] By adopting the above technical solution, a vertical plate 42 is set near the limiting block 4 to fix the spring 41.

[0024] Spring 41 is fixedly connected to the front end of vertical plate 2 42, and the other end of spring 41 is fixedly connected to limit block 2 4. Spring 38 is fixedly connected to the back end of vertical plate 1 39, and the other end of spring 38 is fixedly connected to slider 36.

[0025] By adopting the above technical solution, spring 41 and spring 38 are set so that the limiting wheel 37 and the limiting block 4 can achieve the function of buffering.

[0026] A bending disc 34 is slidably connected to the top of the substrate 1 and between the two upright plates 39. An electric cylinder 35 is fixedly connected to the top of the substrate 1 and near the center of one side. The output end of the electric cylinder 35 is fixedly connected to the bending disc 34.

[0027] By adopting the above technical solution, the electric cylinder 35 is operated, thereby causing the fixedly connected bending disc 34 to move horizontally.

[0028] A short plate 33 is fixedly connected to the top of the limiting plate 31.

[0029] By adopting the above technical solution, a short plate 33 is set at the top of the limiting plate 31 in order to achieve the effect of horizontal movement of the limiting plate 31.

[0030] A lead screw 32 is rotatably connected to the front end of the limiting block 3 and near the top center, and the short plate 33 is threadedly rotatably connected to the lead screw 32.

[0031] By adopting the above technical solution, the lead screw 32 rotates, thereby causing the short plate 33 connected by the threaded rotation to drive the limiting plate 31 to move horizontally.

[0032] A connecting plate 23 is fixedly connected to the back end of the cover 22 near the bottom center, and the connecting plate 23 is slidably connected to the U plate 2.

[0033] By adopting the above technical solution, a connecting plate 23 is set at the back end of the protective cover 22 so as to enable the protective cover 22 to be raised and lowered.

[0034] An electric cylinder 24 is fixedly connected to the top of U-plate 2. The output end of electric cylinder 24 passes through U-plate 2 and is fixedly connected to connecting plate 23.

[0035] By adopting the above technical solution, the electric cylinder 24 is operated, thereby causing the fixedly connected connecting plate 23 to drive the protective cover 22 to rise and fall.

[0036] Working principle: When using this device, the steel pipe is first placed between the two limiting blocks 3 and the limiting plate 31. Then, the screw 32 is rotated, which causes the threaded short plate 33 to move the limiting plate 31 horizontally, thereby limiting the steel pipe. Before bending, the electric cylinder 24 is operated, which causes the fixed connecting plate 23 to move the protective cover 22 downward, thereby achieving the effect of sealing the working environment. This solves the problem that bending the steel pipe will generate a lot of dust and impurities, which pollute the environment and affect the health of the surrounding people.

[0037] By operating the electric cylinder 35, the fixedly connected bending disc 34 slides above the base plate 1. When the steel pipe moves, it will abut against the limit block 4 and squeeze the spring 41. After the steel pipe is bent, the electric cylinder 35 is reversed, which can make the steel pipe rebound quickly. Then, with the cooperation of the two limit wheels 37, the slider 36, the spring 38, and the upright plate 39, the phenomenon of rapid rebound of the steel pipe can be prevented. This solves the problem that the steel pipe will shake and rebound, requiring manual support to stabilize it, which can easily lead to injury to the operator.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
