Description

Technical Field

[0001] The present application relates to the technical field of steel plate roll forming, and in particular to a steel plate roll forming device. Background Art

[0002] Roll forming technology refers to a process that relies on the plastic movement characteristics of materials and adopts the principle of rolling extrusion to form various complex parts. Rolling deformation is line contact and is carried out continuously and step by step. The required deformation force is small, and one stroke can produce one or several workpieces.

[0003] At present, the roll forming of steel plates generally adopts the assembly line mode. During the production process of steel plates, the steel plate coils are fed into the roll forming equipment and enter the multi-stage roll forming stage. In this stage, the steel plate will pass through a series of carefully designed roll forming dies to form it into the required shape by continuous bending. The number and arrangement of these roll forming dies depend on the grade of the steel plate, the complexity of the finished parts and the design of the rolling mill. After the steel plate has been multi-stage roll forming, it is cut to size by the cutting machine at the discharge point to cut the steel plate into the required size.

[0004] However, this mode is limited to the roll cutting and forming of straight-shaped steel plates. When facing the production of curved steel plates, the above-mentioned production line needs to add additional curved processing equipment to complete the curved processing, and then perform independent cutting steps, which not only reduces the processing efficiency, but also increases the processing cost.

DETAILED DESCRIPTION

[0026] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The steel plate roll forming device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 6 As shown, the steel plate roll forming device of the embodiment of the present application may include a base 10, a bending mechanism (not shown in the figure), a cutting mechanism 30 and a linkage mechanism (not shown in the figure).

[0029] Among them, two first side frames 11 and two second side frames 12 are arranged side by side on the base 10. The bending mechanism may include a first pressing roller 21, a second pressing roller 22 and a driving assembly 23, wherein the first pressing roller 21 is movably arranged between the two first side frames 11. The second pressing roller 22 is located obliquely below the first pressing roller 21, and the second pressing roller 22 is movably arranged on the moving frame 13. The bottom of the moving frame 13 is provided with a cylinder 14, and the relevant personnel can adjust the height of the moving frame 13 through the cylinder 14, thereby realizing the adjustment of the height of the second pressing roller 22. The driving assembly 23 is connected to the first pressing roller 21 and the second pressing roller 22 respectively.

[0030] It should be noted that the driving assembly 23 described in this embodiment can drive the first pressing roller 21 and the second pressing roller 22 to rotate synchronously, and the rotation directions of the first pressing roller 21 and the second pressing roller 22 are opposite, so that the steel plate 60 can be conveyed.

[0031] The driving assembly 23 may include a limiting sleeve 231, a connecting member 232, a linkage shaft 233 and a driving motor 234, wherein the limiting sleeve 231 is arranged on the base 10, and a first arc-shaped sliding hole 2311 is arranged on the limiting sleeve 231, one end of the connecting member 232 is connected to the moving frame 13, and a limiting frame 2321 is arranged on the other end. A slave gear 2331 is sleeved on the outer side of the linkage shaft 233, and the slave gear 2331 is meshed with the main gear 211 at the end of the first pressing roller 21, and the linkage shaft 233 is connected to the second pressing roller 22 through a synchronous belt 50, and the linkage shaft 233 is sequentially arranged to penetrate the first arc-shaped sliding hole 2311 and the limiting frame 2321. The driving motor 234 is arranged on the connecting member 232, and its output end is connected to the second pressing roller 22, and the driving motor 234 can directly drive the second pressing roller 22 to rotate.

[0032] It should be noted that the first arc-shaped slide hole 2311 described in this embodiment is set in a lower arc shape, and its virtual center is the main gear 211, so as to ensure that during the movement of the linkage shaft 233 driving the slave gear 2331, the slave gear 2331 can always maintain a meshing connection state with the main gear 211. The first arc-shaped slide hole 2311 and the limit frame 2321 described in this embodiment can jointly limit the linkage shaft 233, and during the adjustment of the height of the second pressure roller 22, the connecting member 232 can move in the height direction with the movable frame 13, so that the linkage shaft 233 can be adaptively adjusted in position on the first arc-shaped slide hole 2311 and the limit frame 2321, and in this process, the linkage shaft 233 and the second pressure roller 22 can be smoothly transmitted through the synchronous belt 50.

[0033] It is understandable that the driving assembly 23 described in this embodiment can drive the synchronous rotation of the first pressing roller 21 and the second pressing roller 22 through a driving motor 234. And the driving assembly 23 can smoothly drive the first pressing roller 21 and the second pressing roller 22 to rotate synchronously while the height of the second pressing roller 22 is adjusted, which does not affect the normal operation of both and effectively reduces the cost. This design ensures the stability of the steel plate 60 during the transmission process and improves the transmission efficiency and quality of the first pressing roller 21 and the second pressing roller 22 for the steel plate 60.

[0034] As a possible situation, the driving assembly 23 may include two motors, and the two motors are connected to the first pressing roller 21 and the second pressing roller 22 respectively, so that the first pressing roller 21 and the second pressing roller 22 are driven to rotate by the two motors respectively.

[0035] The cutting mechanism 30 may include a mounting frame 31 and a template assembly 32, wherein the mounting frame 31 is disposed between the two second side frames 12. The template assembly 32 is detachable and disposed on the mounting frame 31, and the template assembly 32 may include an upper plate 321 and a lower plate 322 disposed up and down, the upper plate 321 being slidably disposed on the mounting frame 31, and a telescopic motor 33 connected to the upper plate 321 is disposed on the mounting frame 31. The mounting frame 31 is disposed in an inverted U-shape, the telescopic motor 33 is disposed at the top of the mounting frame 31, and its output end passes through the mounting frame 31 and is connected to the upper plate 321, and the telescopic motor 33 can directly drive the upper plate 321 to move linearly, thereby adjusting the distance between the upper plate 321 and the lower plate 322.

[0036] It should be noted that the template assembly 32 , the first pressing roller 21 and the second pressing roller 22 described in this embodiment are all detachable and replaceable, so as to facilitate corresponding roll-forming operations for steel plates 60 of different shapes.

[0037] The linkage mechanism may include two linkage components 40, which are respectively arranged on both sides of the base 10, and each linkage component 40 may include a linkage gear 41, a rack 42 and a connecting arm 43, wherein the linkage gear 41 is sleeved on the outside of the first pressing roller 21, the rack 42 is connected to the moving frame 13, and the rack 42 is meshed with the linkage gear 41, the rack 42 is slidably connected to the corresponding first side frame 11, one end of the connecting arm 43 is connected to the linkage gear 41, and the other end of the connecting arm 43 is connected to the mounting frame 31. The connecting arm 43 is movably sleeved on the outside of the first pressing roller 21, so that the first pressing roller 21 can limit the connecting arm 43.

[0038] It should be noted that the rack 42 described in this embodiment can move with the movable frame 13. During the movement of the rack 42 in the height direction, it can drive the interlocking gear 41 meshing with it to rotate accordingly, so that the connecting arm 43 drives the mounting frame 31 to rotate together, thereby realizing the adjustment of the position and angle of the cutting mechanism 30.

[0039] Specifically, when arc rolling and cutting operations are required on the steel plate 60 , the relevant personnel first pass the steel plate 60 between the first pressing roller 21 and the second pressing roller 22 , and then pass it between the upper plate 321 and the lower plate 322 .

[0040] The driving assembly 23 drives the first pressing roller 21 and the second pressing roller 22 to rotate synchronously in opposite directions to transfer the steel plate 60 to the cutting mechanism 30 . During the process, relevant personnel can control the upper plate 321 to cut the steel plate 60 through the telescopic motor 33 .

[0041] During the rolling process, relevant personnel can flexibly adjust the height of the second pressing roller 22 according to the required arc angle of the steel plate 60, and control the movable frame 13 and the second pressing roller 22 on the movable frame 13 through the cylinder 14 to adjust the height. During the adjustment process, the rack 42 can move with the movable frame 13. During the movement of the rack 42 in the height direction, it can drive the interlocking gear 41 meshing with it to rotate accordingly, so that the connecting arm 43 drives the mounting frame 31 to rotate together, so that the position and angle of the cutting mechanism 30 can be adjusted, so that the cutting mechanism 30 can flexibly adapt to the rolling cutting requirements of various arc-shaped steel plates 60, and realize efficient operational adaptability.

[0042] In summary, the steel plate roller forming device of the embodiment of the present application can flexibly adjust the height of the second pressing roller according to the required arc angle of the steel plate. During the adjustment process, the linkage mechanism will adjust the position and angle of the cutting mechanism accordingly, ensuring that the cutting mechanism can flexibly adapt to the roller cutting requirements of various arc-shaped steel plates, thereby achieving efficient operational adaptability.
