Description

Technical Field

[0001] The utility model relates to a section steel roll forming structure, belonging to the technical field of section steel processing and forming. Background Art

[0002] A steel roll-forming device is typically used for cold-bent steel sections. This equipment typically consists of several key components: a feed mechanism, a roll-forming mechanism, a cutting mechanism, a transmission mechanism, and a control mechanism. The roll-forming mechanism is the core component of the entire steel section forming system. It comprises a series of forming wheels and rollers. Each set of forming wheels and rollers sequentially presses and bends the steel sheet into a desired shape, such as a C-shaped, U-shaped, or Z-shaped section, to suit the desired size and shape.

[0003] In the prior art, a utility model patent with Chinese patent authorization publication number CN219188346U discloses a roll-forming machine comprising a frame on which are rotatably mounted a plurality of rollers for forming steel bars into C-shaped steel. The rollers are divided into an upper roller group and a lower roller group, each consisting of multiple pairs of rollers arranged opposite each other. A punch for punching holes in the C-shaped steel and a clamping mechanism for compacting the C-shaped steel are slidably mounted on the frame. The machine maintains stability during punching, reducing the probability of deviation in the C-shaped steel. However, the above technical solution still has the following problems when in use: its roller-pressing wheel is directly fixed on the pressure roller. When it is necessary to process steel products of different shapes, it can only be achieved by replacing the entire roller group or using another suitable forming machine. There are problems of cumbersome operation and poor applicability. At the same time, the roller-pressing wheel directly fixed on the pressure roller is also very troublesome when it needs to be maintained or replaced. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example: Please refer to Figures 1 to 4This embodiment provides a steel section roll forming structure, comprising a symmetrically arranged gantry 1 and a plurality of roller groups rotatably connected between the two gantry frames 1 via bearings. The specific number of roller groups can be determined according to actual conditions. In this embodiment, there are four roller groups. Each roller group comprises a first roller 2 and a second roller 3. Both ends of the first roller 2 and the second roller 3 are rotatably connected to the gantry 1 on the corresponding side via bearings. The first roller 2 is arranged above the second roller 3. A first forming wheel 4 is fixedly provided on each first roller 2. The first forming wheel 4 and the first roller 2 are connected in a common non-detachable manner, which has the characteristic of structural stability. A second forming wheel is provided on each second roller 3. The position of the second forming wheel is adapted to the position of the corresponding first forming wheel 4 so as to cooperate with the first forming wheel 4 to perform the required forming work on the passing steel coil material.

[0023] In this embodiment, the second forming wheel includes a fixed wheel 5 fixedly mounted on the second pressure roller 3. The fixed wheel 5 and the second pressure roller 3 also adopt a common non-detachable connection structure to ensure stability by reducing the connection point. The forming roller 6 is connected to the fixed wheel 5. The forming roller 6 includes a first half wheel 7 and a second half wheel 8. The side wall of the first half wheel 7 is provided with an L-shaped snap-in block 9, and the side wall of the second half wheel 8 is provided with a snap-in groove 10 that adapts to the snap-in block 9. The first half wheel 7 and the second half wheel 8 are connected by the snap-in block 9 and inserted into the snap-in groove 10, forming a complete wheel structure. The complete wheel structure formed by the first half wheel 7 and the second half wheel 8 can cooperate with the first forming wheel 4 to perform appropriate forming processing on the steel coil material passing through. A first connecting hole 11 is formed in each of the first and second wheel halves 7 and 8, and a second connecting hole 12 is formed in the fixed wheel 5. After the first and second wheel halves 7 and 8 are staggered and snap-fitted together, common connecting members in the prior art are inserted into the first and second connecting holes 11 and 12 to removably connect to the fixed wheel 5. The connecting members may be common connecting members such as high-strength bolts and screws.

[0024] Through the above-mentioned settings, by setting the second forming wheel as a fixed wheel 5 and a forming roller 6, setting the forming roller 6 as a structure of staggered bite connection by the first half wheel 7 and the second half wheel 8, and the forming roller 6 and the fixed wheel 5 are detachably connected through a connecting piece, when it is necessary to process steel products of different shapes, the forming roller 6 can be removed from the fixed wheel 5 by removing the connecting piece from the first connecting hole 11 and the second connecting hole 12, and then separating the first half wheel 7 and the second half wheel 8. Thereafter, other forming rollers 6 with outer walls having a suitable shape are replaced, so as to meet the processing requirements of steel products of different shapes. At the same time, in actual use, other forming rollers 6 with a suitable outer diameter can also be replaced. If other forming rollers 6 with different outer diameters are replaced, the first forming wheel 4 selects a first forming wheel 4 with a suitable outer diameter to match the replaced forming roller 6 according to actual conditions. The first forming wheel 4 can also be made into the same structure as the forming roller 6 so that the outer diameter can be changed when needed. The detachable installation method also facilitates maintenance and replacement operations, and has the advantages of good applicability and easy operation. In addition, the forming roller 6 can be omitted from the fixed wheel 5 according to actual needs. In this case, the fixed wheel 5 can also serve as a conveying wheel to appropriately convey the steel coil material. For example, when processing C-shaped steel, the forming roller 6 can be omitted. In this case, the fixed wheel 5 plays a conveying role, and the first forming wheel 4 mainly shapes the passing steel coil material, that is, C-shaped steel can be processed. When it is necessary to process ribs on the C-shaped steel, the forming roller 6 can be installed on the fixed wheel to appropriately process the C-shaped steel.

[0025] To ensure the normal forming process, one of the roller groups is also equipped with a drive shaft 13. The drive shaft 13 is fixedly connected to the second roller 3 in the corresponding roller group. The drive shaft 13 can be connected to the power shaft of an external drive motor, so that when the drive motor starts working, it can drive the corresponding second roller 3 to rotate. Adjacent roller groups are connected by a transmission assembly. The transmission assembly includes a transmission sprocket 14, which is provided on each second roller 3. Adjacent second rollers 3 are connected together by a transmission chain 15 provided between the transmission sprockets 14 in corresponding positions. This allows the drive shaft 13 to drive the corresponding second roller 3 to rotate, and the rotating second roller 3 can drive the remaining second rollers 3 to follow the rotation through the transmission assembly. In this embodiment, along the direction of movement of the steel coil, the driving shaft 13 is fixedly connected to the second second pressing roller 3, one transmission sprocket 14 is provided on each of the first and fourth second pressing rollers 3, and two transmission sprockets 14 are provided on each of the second and third second pressing rollers 3. One of the transmission sprockets 14 provided on the second and third second pressing rollers 3 is connected to the transmission chain 15, the other transmission sprocket 14 provided on the second second pressing roller 3 is connected to the transmission sprocket 14 on the first second pressing roller 3 via the transmission chain 15, and the other transmission sprocket 14 provided on the third second pressing roller 3 is connected to the transmission sprocket 14 on the fourth second pressing roller 3 via the transmission chain 15. This ensures that when the second second pressing roller 3 rotates, the remaining second pressing rollers 3 can rotate accordingly.

[0026] The pressure roller group is also provided with a linkage component. The pressure roller group provided with the linkage component and the pressure roller group not provided with the linkage component are staggered. In this embodiment, the linkage component is provided on the first and third second pressure rollers 3. The linkage component includes a first gear 16 and a second gear 17. The first gear 16 is fixedly mounted on the first pressure roller 2, and the second gear 17 is fixedly mounted on the second pressure roller 3. The first gear 16 and the second gear 17 are meshed together, so that when the second pressure roller 3 rotates, it drives the second gear 17 to rotate, that is, it can drive the first pressure roller 2 to rotate under the action of the second gear 17 and the first gear 16.

[0027] The working principle of the present invention is that when performing the forming operation, the gantry 1 is moved to the appropriate position by the slider 13. This forming structure can be set to one or more according to actual production needs. After the forming structure is adjusted to the appropriate position, the external drive motor is activated to start the operation, causing the second pressure roller 3 to rotate with the first pressure roller 2 in the appropriate position, thereby driving the first forming wheel 4 and the second forming wheel in the appropriate position to rotate, thereby performing the forming operation. After that, the steel coil material passes through the first forming wheel 4 and the second forming wheel, and the corresponding forming operation can be performed. In this embodiment, the second first pressure roller 2 and the fourth first pressure roller 2 are unpowered pressure rollers. By staggering the unpowered and powered pressure rollers, the load variation during the operation of the equipment can be reduced, thereby improving production efficiency and equipment stability. Moreover, because not all pressure rollers need to be continuously operated, the pressure rollers to be used can be selected according to actual needs, which can also save energy. It should be noted that in actual use, the structures of each first pressure roller 2, the second pressure roller 3, and each first forming wheel 4 and the second forming wheel can be inconsistent, and they can be adjusted accordingly according to actual processing needs.

[0028] In this embodiment, in order to increase the diversity of steel materials formed by the forming structure, the first pressing roller 2 and the second pressing roller 3 are both symmetrically arranged between the two side gantries 1. The first pressing roller 2 is provided with a first forming wheel 4, and the second pressing roller 3 is provided with a second forming wheel. Adjusting rollers 18 are movably inserted between the first pressing rollers 2 and the second pressing rollers 3. The adjusting rollers 18 are connected to the first pressing rollers 2 and the second pressing rollers 3 by sliding keys. That is, the first pressing rollers 2 can slide along the corresponding adjusting rollers 18 and rotate synchronously with them, and the second pressing rollers 3 can slide along the corresponding adjusting rollers 18 and rotate synchronously with them. Sliders 19 are provided at the bottom of the two side gantries 1. The slides 19 match the external slide rails. The direction in which the slides 19 slide on the external slide rails is adapted to the direction in which the first pressing rollers 2 and the second pressing rollers 3 move on the corresponding adjusting rollers 18. Through the above-mentioned arrangement, external driving components, such as cylinders, can be connected to the gantries 1 on both sides. Through the operation of the driving components, the sliders 19 on the gantries 1 on both sides can slide on the matching external slide rails, that is, the first pressing rollers 2 on both sides and the second pressing rollers 3 on both sides can slide along the corresponding adjusting rollers 18, so that the distance between the first forming wheels 4 on both sides and the distance between the second forming wheels on both sides can be adjusted, so that steels of various shapes can be formed.
