By designing a flexible combination of the moving bending roller assembly and the fixed bending roller, the bending pressure of the roller is flexibly adjusted by using an adjusting screw and a slider structure. The adjusting screw drives the moving slider and the roller sleeve to rise and fall to adjust the bending pressure. The limiting protrusion and the vertical groove slide together to prevent detachment.
It enables flexible adjustment of the bending curvature of products by roller bending, reduces the steps of changing bending rollers, and improves the efficiency of roller extrusion forming of products with different curvatures.

Description
Technical Field
[0001] This utility model relates to the field of bending roller forming technology, and in particular to a bending roller forming device. Background Technology
[0002] Bending rollers are a common type of metal processing equipment used to bend metal sheets or tubes into desired shapes. Their working principle primarily relies on the pressure and bending force between two bending rollers to achieve the bending of the metal.
[0003] During the bending roll forming process, the product needs to have various degrees of curvature, so the curvature of the product needs to be adjusted by adjusting the pressure between the bending rolls. The existing bending rolls cannot be adjusted in position in the whole bending device, so the pressure between the two bending rolls cannot be adjusted. It is necessary to replace the bending rolls with different sizes, which is inconvenient.
[0004] Therefore, it is essential to provide a bending roller forming device to address the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a bending roller forming device. This bending roller forming device achieves flexible adjustment of the bending pressure by flexibly cooperating with the moving bending roller assembly and the fixed bending roller, thereby flexibly adjusting the bending arc of the roller-bent product, reducing the steps of changing bending rollers, and improving the efficiency of bending roller extrusion forming of products with different arcs.
[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.
[0007] A bending roller forming device is provided, including two trapezoidal side plates, each of which has a U-shaped groove. A portal frame is fixedly installed inside the U-shaped groove. A movable bending roller assembly is installed on the two portal frames. A fixed bending roller is also rotatably installed on the two trapezoidal side plates. The fixed bending roller and the movable bending roller assembly are in roller bending cooperation.
[0008] The movable bending roller assembly includes an upper positioning plate that fixes two portal frames together. An adjusting screw is spirally installed in the center of the upper positioning plate. Two movable sliders are fixedly installed and slidably installed inside each portal frame. A movable roller shaft is rotatably installed on the two movable sliders. A movable roller sleeve is fixedly installed on the movable roller shaft. The two movable sliders are also fixedly connected by a bending connecting plate. The bottom of the adjusting screw is rotatably installed on the bending connecting plate.
[0009] Specifically, each movable slider is equipped with two limiting protrusions, and a vertical groove is provided on the inner wall of the portal frame, with the limiting protrusions slidingly engaging with the vertical groove.
[0010] Preferably, a bottom positioning plate is fixedly installed at the bottom of the trapezoidal side plate, and a positioning bolt is movably installed on the bottom positioning plate.
[0011] Specifically, an adjustment handle is fixedly installed on the top of the adjusting screw.
[0012] This invention achieves flexible adjustment of the bending pressure by using a movable bending roller assembly and a fixed bending roller in a flexible manner, thereby enabling flexible adjustment of the bending arc of the roller-bent product. This reduces the steps of changing bending rollers and improves the efficiency of roller extrusion forming of products with different arcs. Attached Figure Description

[0033] The present invention will be further described in conjunction with the following embodiments.
[0034] Example 1.
[0035] like Figure 1-3 As shown, a bending roller forming device includes two trapezoidal side plates 1, each of which has a U-shaped groove 2. A portal frame 3 is fixedly installed inside the U-shaped groove 2. Movable bending roller assemblies are installed on the two portal frames 3. Fixed bending rollers 4 are also rotatably installed on the two trapezoidal side plates 1. The fixed bending rollers 4 and the movable bending roller assemblies are in roller bending cooperation.
[0036] This application is used for roll bending of metal sheets or pipes using bending rollers. First, the moving bending roller assembly and the fixed bending roller 4 are positioned by two trapezoidal side plates 1 and two portal frames 3. Then, the moving bending roller assembly and the fixed bending roller 4 are used to roll extrude and form the metal sheets or pipes. The rolling pressure is adjusted by moving the moving bending roller assembly, thereby realizing the roll bending of products with different curvatures.
[0037] The movable bending roller assembly includes an upper positioning plate 5 that fixes two portal frames 3 together. An adjusting screw 6 is spirally installed in the center of the upper positioning plate 5. Two movable sliders 7 are fixedly installed and slidably installed inside each portal frame 3. A movable roller shaft 8 is rotatably installed on the two movable sliders 7. A movable roller sleeve 9 is fixedly installed on the movable roller shaft 8. The two movable sliders 7 are also fixedly connected by a bending connecting plate 10. The bottom of the adjusting screw 6 is rotatably installed on the bending connecting plate 10.
[0038] The movable bending roller assembly adjusts the lifting and lowering displacement of the adjusting screw 6 by rotating the adjusting screw 6. At the same time, the adjusting screw 6 drives the bending connecting plate 10 at the bottom to rise and fall. The bending connecting plate 10 can then drive the two movable sliders 7 to rise and fall. The two movable sliders 7 drive the movable roller shaft 8 and the movable roller sleeve 9 to achieve lifting and lowering adjustment, thereby adjusting the distance between the movable roller sleeve 9 and the fixed bending roller 4 and adjusting the roller bending pressure.
[0039] Each movable slider 7 is equipped with two limiting protrusions 11, and a vertical groove 12 is provided on the inner wall of the portal frame 3. The limiting protrusions 11 and the vertical groove 12 slide in cooperation.
[0040] The limiting protrusion 11 and the vertical groove 12 on the movable slider 7 slide together to prevent the movable slider 7 from falling off and to achieve directional sliding.
[0041] A bottom positioning plate 13 is fixedly installed at the bottom of the trapezoidal side plate 1, and a positioning bolt 14 is movably installed on the bottom positioning plate 13.
[0042] The bottom positioning plate 13 facilitates the fixing of the trapezoidal side plate 1, which can be fixed to the ground or other flat working platform by means of positioning bolts 14.
[0043] An adjustment handle 15 is fixedly installed on the top of the adjusting screw 6.
[0044] The adjustment screw 6 is rotated by adjusting the handle 15.
[0045] This invention achieves flexible adjustment of the bending pressure by using the flexible cooperation between the movable bending roller assembly and the fixed bending roller 4, thereby enabling flexible adjustment of the bending arc of the product. This reduces the steps of changing bending rollers and improves the efficiency of bending roller extrusion forming of products with different arcs.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
