Description

Technical Field

[0001] This utility model relates to the technical field of plate rolling, and in particular to a plate rolling device for high-speed railway rib top plate. Background Technology

[0002] The rail transit vehicle is equipped with a roof plate component. The roof plate component is made of aluminum sheet and is formed by pressing ribs. The ribs on the roof plate have ventilation holes. The roof plate component is shaped like a large arc and is manufactured using a plate rolling forming process. Because the ribs are not continuous ribs when formed, and the plate rolling machine consists of three rollers, one upper roller and two lower rollers, forming a triangular structure, the plate rolling machine often cannot roll the plate at the ends of the middle roof plate product because the two ends cannot overlap, or the length is insufficient to form the arc at the ends. This greatly troubles and affects the product quality, and also indirectly leads to excessively high production costs. Utility Model Content

[0003] The purpose of this utility model is to provide a high-speed rail rib roof plate rolling forming device to address the defects in the existing technology. This device solves the problems of inability to roll the plate due to the inability of the two ends to overlap, as well as the problems of inability to roll the plate due to deformation of products with different heights after forming. At the same time, it also reduces production costs.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a high-speed railway ribbed top plate rolling forming device, comprising a main pad plate, a secondary pad plate, and a rolling machine cooperating with the main pad plate and the secondary pad plate; the secondary pad plate is fixed above the main pad plate and forms a reference positioning area at a distance from the end face of the main pad plate; the height of the secondary pad plate is the same as the thickness of the high-speed railway ribbed top plate, the overall height of the main pad plate and the secondary pad plate is the same as the height of the high-speed railway ribbed top plate after rolling forming, and the reference positioning area is adapted to the areas at both ends of the high-speed railway ribbed top plate that need to be rolled forming.

[0005] Furthermore, the auxiliary pads are provided in two sets, respectively located at both ends of the main pad, and the reference positioning area is reserved above both ends of the main pad.

[0006] Furthermore, the main pad and the auxiliary pad are fixed by the upper roller and one of the lower rollers of the plate rolling machine, and the high-speed rail rib top plate overlaps the reference positioning area from the direction of the other lower roller.

[0007] Furthermore, when the main pad and the auxiliary pad are fixed by the upper roller and one of the lower rollers of the plate rolling machine, the end face of the auxiliary pad in the overlapping direction of the top plate of the high-speed rail rib is located below the central axis of the upper roller of the plate rolling machine.

[0008] Furthermore, the main pad and the secondary pad are non-metallic plates with toughness.

[0009] Furthermore, an adjustment area for the position of the secondary pads is provided between the two secondary pads above the main pad.

[0010] The system comprises a main pad, a secondary pad, and a plate rolling machine that cooperates with the main pad and the secondary pad. The secondary pad is fixed above the main pad and forms a reference positioning area at a distance from the end face of the main pad. The height of the secondary pad is the same as the thickness of the high-speed rail rib top plate. The overall height of the main pad and the secondary pad is the same as the height of the high-speed rail rib top plate after rolling. The reference positioning area is adapted to the areas at both ends of the high-speed rail rib top plate that need to be rolled. This structure solves the curvature problem caused by the inability to roll the plate due to the inability to overlap the ends, as well as the curvature problem caused by deformation during the rolling process of products with different heights after forming. At the same time, it also reduces production costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] A high-speed railway ribbed roof slab rolling forming device, such as Figure 1 , 2 As shown, it includes a main pad plate 1, a secondary pad plate 2, and a plate rolling machine 3 that cooperates with the main pad plate 1 and the secondary pad plate 2; the secondary pad plate 2 is fixed above the main pad plate 1 and forms a reference positioning area 4 at a distance from the end face of the main pad plate 1; the height of the secondary pad plate 2 is the same as the thickness of the high-speed rail rib top plate 5, the overall height of the main pad plate 1 and the secondary pad plate 2 is the same as the height of the high-speed rail rib top plate 5 after plate rolling, and the reference positioning area 4 is adapted to the areas at both ends of the high-speed rail rib top plate 5 that need to be rolled.

[0021] Specifically, the main pad 1 serves as the foundation of the entire rolling auxiliary device. Its robust structural design ensures stable support during the rolling process. The cooperation between the main pad 1 and the auxiliary pad 2 allows the top plate to maintain continuous and consistent edge stress during rolling, thereby optimizing the rolling forming effect and ensuring that the curvature contours at both ends of the product meet design requirements. By adjusting the size and shape of the main pad 1, it can be adapted to high-speed rail ribbed top plates 5 of different specifications and sizes, improving the versatility and flexibility of the device. The auxiliary pad 2 is fixed above the main pad 1 and forms a reference positioning area 4 at a distance from the end face of the main pad 1, thereby enabling precise positioning of both ends of the high-speed rail ribbed top plate 5. The auxiliary pad 2 ensures the accuracy of the forming position of the rolled plate. With the assistance of the auxiliary pad 2, rework and scrap caused by poor end forming can be significantly reduced, thereby improving production efficiency and product quality. By matching the height of the auxiliary pad with the thickness of the top plate, it can be ensured that the top plate is evenly supported during the rolling process, avoiding forming deviations caused by insufficient or excessive support. At the same time, the overall height of the main pad and the auxiliary pad matches the height of the top plate after forming, which helps to achieve precise forming control, ensure the dimensional accuracy of the product, and help optimize the rolling forming process, so that the top plate can maintain a stable shape and size during the rolling process, thereby improving product quality and consistency.

[0022] As a preferred embodiment of the above, such as Figure 1As shown, the auxiliary pad 2 is provided in two sets, which are respectively located at both ends of the main pad 1, and the reference positioning area 4 is left above both ends of the main pad 1.

[0023] Specifically, by setting auxiliary pads 2 at the ends of the two main pads 1 respectively and leaving a reference positioning area 4, the precise positioning of both ends of the high-speed rail rib top plate can be achieved. This helps to ensure the position accuracy of both ends of the top plate during the rolling process, thereby improving the forming quality. Furthermore, it matches the rolling requirements of both ends of the high-speed rail rib top plate 5, further reducing production costs and improving rolling efficiency.

[0024] As a preferred embodiment of the above, such as Figure 2 As shown, the main pad 1 and the auxiliary pad 2 are fixed by the upper roller and one of the lower rollers of the plate rolling machine 3, and the high-speed rail rib top plate 5 overlaps to the reference positioning area 4 from the direction of the other lower roller.

[0025] Specifically, the design of the high-speed rail ribbed top plate 5 overlapping the reference positioning area 4 from another lower roller direction ensures that the top plate maintains a stable overlapping state during the rolling process. By fixing the main pad 1 and the auxiliary pad 2 and leaving the reference positioning area 4, precise positioning of the high-speed rail ribbed top plate 5 can be achieved, helping to ensure the accuracy of the top plate's position during the rolling process. This improves the precision and consistency of the formed contour, simplifies the operation process of the rolling forming device, and makes it easier for operators to perform the rolling forming operation of the top plate. This not only improves production efficiency but also reduces operational difficulty and labor intensity. Furthermore, it allows the rolling forming device to be applied to high-speed rail ribbed top plates of different specifications and sizes. The main pad 1 and the auxiliary pad 2 can be adjusted according to actual needs, thus easily adapting to top plates of different lengths, improving the versatility and flexibility of the device.

[0026] As a preferred embodiment of the above, such as Figure 2 As shown, when the main pad 1 and the auxiliary pad 2 are fixed by the upper roller and one of the lower rollers of the plate rolling machine 3, the end face of the auxiliary pad 2 in the overlapping direction of the top plate 5 of the high-speed rail rib is located below the central axis of the upper roller of the plate rolling machine 3.

[0027] Specifically, the placement of the auxiliary pad 2 at a specific position helps to better support and position the high-speed rail rib top plate 5 during the rolling process. The end face position of the auxiliary pad 2 allows the high-speed rail rib top plate 5 to transition more smoothly when overlapping, reducing friction and resistance during the overlapping process, which helps to maintain the stability of the top plate during the rolling process and improve the forming quality.

[0028] As a preferred embodiment of the above, such as Figure 1 As shown, the main pad 1 and the secondary pad 2 are non-metallic plates with toughness.

[0029] Specifically, by selecting a tough non-metallic plate, the main pad 1 and the secondary pad 2 can withstand greater external forces without breaking. They are lightweight, easy to handle, have good weather resistance, and can maintain a stable physical state in extremely cold and hot weather environments. They have a low coefficient of thermal expansion, good dimensional stability, high hardness, good wear resistance, and excellent bending strength. They can maintain good structural integrity when subjected to bending, which makes them very advantageous in some application scenarios that require curved shapes.

[0030] As a preferred embodiment of the above, such as Figure 1 As shown, an adjustment area 6 for the position of the secondary pads 2 is provided between the two secondary pads 2 above the main pad 1.

[0031] Specifically, by adjusting the position of the auxiliary pad 2 within the auxiliary pad position adjustment area 6, precise positioning and fixing of the high-speed railway ribbed top plate can be achieved. This helps ensure the stability and accuracy of the top plate during the rolling process, improving the forming quality. The auxiliary pad position adjustment area 6 also allows the position of the auxiliary pad 2 on the main pad 1 to be adjusted according to actual needs, helping to adapt to high-speed railway ribbed top plates of different specifications and sizes, and improving the versatility and adaptability of the device.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
