Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel plate bending processing technology, and in particular to a cold bending processing device for weather-resistant steel plates. Background Technology
[0002] Weathering steel plates, also known as atmospheric corrosion resistant steel plates, belong to the category of low-alloy high-strength structural steel plates. Based on their main characteristics, they are divided into high-weather-resistant structural steel and weathering steel for welded structures. Currently, cold rolling technology is commonly used to bend weathering steel plates, thus requiring the use of cold bending equipment.
[0003] Existing cold bending processing equipment typically lays the steel plate on the equipment and then uses a bending mechanism to bend the steel plate until it fits into the forming cavity. However, most existing forming cavities have an arc-shaped cross-section, and the size of the forming cavity cannot be adjusted. This makes it difficult to adjust the degree of bending of the steel plate, making it difficult for the equipment to adapt to different bending requirements, affecting the practicality of the equipment, and thus hindering the efficient processing of steel plates. Utility Model Content
[0004] This utility model proposes a cold bending processing device for weathering steel plates to solve the problem that the size of the existing forming cavity cannot be adjusted, which makes it difficult to adjust the bending degree of the steel plate and makes the device unable to adapt to the processing requirements of different bending degrees.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a cold bending processing device for weathering steel plates, including a base and a bending assembly disposed on the base, wherein the top of the base is recessed inward to form an interconnected cavity and a movable cavity, a forming seat is disposed inside the movable cavity, and the top of the forming seat is recessed inward to form an arc groove, and the arc groove and the cavity can be combined to form a forming cavity.
[0006] The base is also provided with an adjustment component that drives the molding seat to move up and down along the movable cavity. The adjustment component includes an installation cavity opened inside the base. The installation cavity is located below the movable cavity and communicates with the movable cavity. A first hydraulic cylinder is installed in the installation cavity, and the telescopic end of the first hydraulic cylinder is fixedly connected to the bottom of the molding seat.
[0007] Preferably, the base is further provided with a pressing assembly for pressing the two ends of the steel plate. The pressing assembly includes two symmetrically distributed first support frames. A second hydraulic cylinder is fixed to the top of each of the two first support frames, and a pressure plate is provided inside each of the two first support frames. The telescopic end of the second hydraulic cylinder extends into the interior of the first support frame and is fixedly connected to the top of the pressure plate. A first opening is provided on the front side of each of the two first support frames to facilitate the placement of the steel plate on the base.
[0008] Preferably, the bending assembly includes a second support frame mounted on the top of the base, a third hydraulic cylinder fixed to the top of the second support frame, and an installation frame inside the second support frame. The installation frame is equipped with rollers for bending the steel plate. The telescopic end of the third hydraulic cylinder extends into the second support frame and is fixedly connected to the top of the installation frame. The second support frame is located between two first support frames, and a second opening is provided on the front side of the second support frame.
[0009] Preferably, both pressure plates are provided with anti-slip pads at their bottoms, and the bottoms of the anti-slip pads are serrated to protect the steel plate. On the one hand, this prevents the steel plate from sliding between the pressure plate and the pressure plate, ensuring that the pressure plate presses the steel plate firmly. On the other hand, it prevents the pressure plate from damaging the steel plate, thus ensuring the processing quality of the steel plate.
[0010] Preferably, both sides of the molding seat are fixed with limit sliders, and the inner wall of the movable cavity is provided with a limit groove for the limit sliders to slide, which can limit the sliding of the molding seat and ensure the stable lifting and lowering of the molding seat.
[0011] Preferably, the base is further provided with an auxiliary support component for auxiliary support of the molding seat, and the auxiliary support component includes multiple cavities opened inside the base. The multiple cavities are distributed on both sides of the mounting cavity, and each of the multiple cavities is provided with a spring and a telescopic auxiliary support rod. The spring is sleeved on the outside of the auxiliary support rod, and the spring and the top end of the auxiliary support rod are fixedly connected to the bottom of the molding seat.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] (1) By adjusting the settings of the components, the height of the forming seat can be adjusted, thereby adjusting the size of the forming cavity and adjusting the degree of bending of the steel plate. This allows the device to meet the processing requirements of different degrees of bending of the steel plate, greatly improving the practicality of the device and facilitating the efficient processing of the steel plate.
[0014] Furthermore, by utilizing auxiliary support components, the forming seat can be limited to ensure stable adjustment, and the forming seat can be provided with auxiliary support to ensure stable bending of the steel plate.
[0015] (2) By setting the pressing component, the steel plate can be pressed tightly, which facilitates the rolling and bending of the steel plate, avoids the steel plate from shifting during rolling and bending, and thus helps the steel plate to be processed stably and improves the rolling and bending efficiency, thereby achieving efficient processing of the steel plate.
[0016] Furthermore, when the pressure plate presses the two ends of the steel plate together, the steel plate can be rolled into a W shape by using the lifting and lowering of the forming seat and the rolling roller. This allows the device to not only process the steel plate into an arc shape, but also into a W shape, further improving the practicality of the device and meeting the different processing requirements of the steel plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0024] like Figures 1-4 As shown, a cold bending processing device for weathering steel plates includes a base 1 and a bending assembly disposed on the base 1. The top of the base 1 is recessed inward to form a cavity 5 and a movable cavity that are interconnected. A forming seat 4 is disposed inside the movable cavity, and the top of the forming seat 4 is recessed inward to form an arc groove. The arc groove and the cavity 5 can be combined to form a forming cavity.
[0025] The base 1 is also provided with an adjustment component that drives the molding seat 4 to move up and down along the movable cavity. The adjustment component includes an installation cavity opened inside the base 1. The installation cavity is located below the movable cavity and communicates with the movable cavity. A first hydraulic cylinder 2 is installed in the installation cavity, and the telescopic end of the first hydraulic cylinder 2 is fixedly connected to the bottom of the molding seat 4.
[0026] Depend on Figures 1-4 It is known that the bending assembly includes a second support frame 12 installed on the top of the base 1, a third hydraulic cylinder 11 fixed at the top of the second support frame 12, and an installation frame 13 is provided inside the second support frame 12. A rolling roller 14 for bending the steel plate is installed inside the installation frame 13. The telescopic end of the third hydraulic cylinder 11 extends into the second support frame 12 and is fixedly connected to the top of the installation frame 13. The second support frame 12 is located between two first support frames 8, and a second opening 16 is also provided on the front side of the second support frame 12.
[0027] During the bending process of weathering steel plate, the steel plate can be placed on the base 1 from one side of the second opening 16, and then the mounting frame 13 is driven to descend by the third hydraulic cylinder 11. Subsequently, the mounting frame 13 drives the roller 14 to descend, so that the roller 14 rolls the middle part of the steel plate into the forming cavity until the bottom of the steel plate is attached to the top of the forming seat 4, thus completing the cold bending process of the steel plate. After processing, the mounting frame 13 is driven to rise by the third hydraulic cylinder 11, so that the mounting frame 13 drives the roller 14 to rise and reset. Then, the worker takes the processed steel plate out of the forming cavity to complete the unloading.
[0028] Furthermore, during the cold bending process of steel plates, the height of the forming seat 4 can be adjusted according to the bending requirements of the steel plate. That is, the forming seat 4 is driven to rise along the movable cavity by the first hydraulic cylinder 2 until the forming seat 4 is adjusted to the required position. Then, the steel plate is bent by the roller 14, thereby adjusting the degree of bending of the steel plate. This allows the device to meet the processing requirements of different degrees of bending of the steel plate, greatly improving the practicality of the device and facilitating the efficient processing of steel plates.
[0029] Furthermore, such as Figure 2 and Figure 3 As shown, both sides of the forming base 4 are fixed with limit sliders 7, and the inner wall of the movable cavity is provided with a limit groove 6 for the limit sliders 7 to slide.
[0030] When the first hydraulic cylinder 2 drives the molding seat 4 to rise and fall, the limiting slider 7 slides along the limiting groove 6 to limit the sliding of the molding seat 4, thereby ensuring the stable rise and fall of the molding seat 4 and facilitating the stable adjustment of the molding seat 4.
[0031] Furthermore, such as Figure 2 and Figure 3As shown, the base 1 is also provided with an auxiliary support member 3 for auxiliary support of the molding seat 4. The auxiliary support member 3 includes multiple cavities opened inside the base 1. The multiple cavities are distributed on both sides of the mounting cavity. Each of the multiple cavities is provided with a spring 31 and a telescopic auxiliary support rod 32. The spring 31 is sleeved on the outside of the auxiliary support rod 32, and the top of the spring 31 and the top of the auxiliary support rod 32 are fixedly connected to the bottom of the molding seat 4.
[0032] During the process of the first hydraulic cylinder 2 driving the forming seat 4 to rise and fall, the forming seat 4 will drive the spring 31 and the auxiliary support rod 32 to extend and retract synchronously. On the one hand, the forming seat 4 can be limited to ensure the stable adjustment of the forming seat 4. On the other hand, it can provide auxiliary support for the forming seat 4 to ensure the stable bending of the steel plate.
[0033] like Figures 1-4 As shown, in this embodiment, the base 1 is also provided with a pressing assembly for pressing the two ends of the steel plate. The pressing assembly includes two symmetrically distributed first support frames 8. The top of each of the two first support frames 8 is fixed with a second hydraulic cylinder 9, and the interior of each of the two first support frames 8 is provided with a pressure plate 10. The telescopic end of the second hydraulic cylinder 9 extends into the interior of the first support frame 8 and is fixedly connected to the top of the pressure plate 10. The front side of each of the two first support frames 8 is provided with a first opening 15.
[0034] During the steel plate bending process, the two pressure plates 10 can be driven to descend synchronously by the second hydraulic cylinders 9 on the two first support frames 8, so that the two pressure plates 10 press down on the top two sides of the steel plate respectively, thereby pressing the steel plate tightly, which facilitates the bending process of the steel plate, avoids the steel plate from shifting during bending, and is conducive to the stable processing of the steel plate. It can also improve the bending process efficiency and achieve high-efficiency processing of the steel plate.
[0035] Furthermore, when the pressure plate 10 presses the two ends of the steel plate together, the steel plate can be rolled into a W shape by utilizing the cooperation between the forming seat 4 and the rolling roller 14. This means that the device can not only process the steel plate into an arc shape, but also into a W shape, which further improves the practicality of the device and meets the different processing requirements of the steel plate.
[0036] Furthermore, to prevent slippage between the pressure plate 10 and the steel plate, and to ensure that the pressure plate 10 stably presses the steel plate, such as... Figures 2-4 As shown, both pressure plates 10 have anti-slip pads at their bottoms, and the bottoms of the anti-slip pads are serrated.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
