Description

Technical Field

[0001] The utility model relates to the technical field of I-beam processing, and particularly relates to a cold bending device for stainless steel I-beams. Background Art

[0002] The I-beam is also called a steel beam, which is a long steel bar with an I-shaped cross-section. The I-shaped steel is divided into hot-rolled I-beams and light I-beams. It is a steel section with an I-shaped cross-section. When the existing I-beams are processed, they need to be bent by a cold bending machine. However, when the existing I-beam cold bending machine is applicable to I-beams of different heights, the height adjustment operation of the limit pressure roller on the gantry is relatively cumbersome and has certain defects. Based on this, a pressure roller adjustment structure for an I-beam cold bending machine is disclosed in Chinese Patent Publication No. CN216324359U, including a base. One side of the top of the base is fixedly connected with an electric telescopic cylinder, and the output end of the electric telescopic cylinder is fixedly connected with a pressure wheel. Fixed frames are arranged at both ends of the top of the base. A guide block is arranged at the bottom of the fixed frame, and a guide groove corresponding to the guide block is arranged on the top of the base. A support roller is arranged in the fixed frame, and the support roller is fixedly connected with the inner bottom of the fixed frame through a connecting block. A pressure roller is arranged above the support roller, and threaded rods are inserted into both ends of the pressure roller, and the top ends of the threaded rods are fixedly connected with the inner top of the fixed frame;

[0003] The beneficial effect of the above patent technology is that the height of the pressure roller can be effectively adjusted through the setting of the adjustment mechanism, so as to adapt to I-beams of different heights. However, through the specification and the specification drawings of the above patent technology, it can be seen that when the above patent technology is used for cold bending processing of I-beams, a conveying device for conveying the I-beams is not provided, resulting in that workers still need to convey the I-beams through additional equipment or manual methods when bending the I-beams. Using the manual handling method for conveying will increase the labor intensity of workers, and using equipment for conveying will not only increase the labor cost of the factory, but also increase the floor area of the equipment. Therefore, there are still some deficiencies.

[0004] In summary, it is very necessary to invent a cold bending device for stainless steel I-beams. Summary of the Invention

[0021] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0022] Refer to the attached Figures 1-4, a cold bending device for stainless steel I-beams provided by the utility model includes a processing table 100. A telescopic cylinder a110 is fixed at the center of the rear side of the outer wall top of the processing table 100. A pipe bending component is arranged at the front end of the outer wall of the telescopic cylinder a110. The arranged telescopic cylinder a110 can drive a clamping frame a120 to move through its output end in a pneumatic manner. The arranged clamping frame a120 is used to clamp a pressing wheel 121. The pipe bending component includes the clamping frame a120. The front end of the outer wall of the telescopic cylinder a110 is fixedly connected to the rear end of the outer wall of the clamping frame a120 through the output end. The upper and lower ends of the inner wall of the clamping frame a120 are rotatably connected with the pressing wheel 121. A driving motor a122 is arranged at the top of the outer wall of the clamping frame a120 and at a position corresponding to the pressing wheel 121. The bottom end of the driving motor a122 is connected to the top end of the pressing wheel 121. When the telescopic cylinder a110 pushes the clamping frame a120 and the pressing wheel 121 to move, the arranged pressing wheel 121 can bend the stainless steel I-beam body 200 according to the extended length. The arranged driving motor a122 is used to drive the pressing wheel 121 to rotate through the output shaft, so that when the pressing wheel 121 bends the stainless steel I-beam body 200, it can also convey the stainless steel I-beam body 200;

[0023] On the outer wall top of the processing table 100 and on both sides of the telescopic cylinder a110, auxiliary cold bending components are provided. The auxiliary cold bending components include gantry frames 300, bottom rotating rollers 330, upper pressing components and side positioning and conveying components. The outer wall bottoms of the two gantry frames 300 are fixed to both sides of the outer wall top of the processing table 100. The upper pressing components are arranged at the inner wall tops of the gantry frames 300. The front and rear ends of the bottom rotating rollers 330 are respectively fixedly connected to the front and rear ends of the inner walls of the gantry frames 300. The arranged upper pressing components are used to cooperate with the bottom rotating rollers 330 to limit the height of the stainless steel I-beam body 200 at different heights. The upper pressing components include upper pressing plates 310. The upper pressing plates 310 are arranged above the outer wall tops of the bottom rotating rollers 330. Ball bearings 311 are arranged at the outer wall bottoms of the upper pressing plates 310. The arranged ball bearings 311 can roll on the outer wall bottoms of the upper pressing plates 310, so as to avoid the stainless steel I-beam body 200 being unable to move due to large frictional force after the upper pressing plates 310 press the outer wall tops of the stainless steel I-beam body 200. The center of the outer wall top of the upper pressing plate 310 is rotatably connected to a screw rod 320. The upper end of the screw rod 320 is threadedly connected to the inner wall top of the gantry frame 300. Workers can rotate the screw rod 320 so that the screw rod 320 can drive the upper pressing plate 310 to move up and down through the cooperation of the threaded connection with the gantry frame 300, thereby being able to adjust the height of the upper pressing plate 310. Guide rods are fixedly arranged at the front and rear ends of the outer wall top of the upper pressing plate 310 and on both sides of the screw rod 320. The outer wall top of the gantry frame 300 is slidably connected to the outer walls of the guide rods. The arranged guide rods are used to limit the moving direction of the upper pressing plate 310 without affecting the movement of the upper pressing plate 310;

[0024] The side positioning and conveying component is arranged at the front and rear ends of the inner wall of the gantry 300. The side positioning and conveying component is provided to clamp the front and rear ends of the stainless steel I-beam body 200 and cooperate with the pressing wheel 121 and the driving motor a122 to move and convey the stainless steel I-beam body 200. The side positioning and conveying component includes a mounting frame 340. One end of the mounting frame 340 is fixedly connected to the front end of the inner wall of the gantry 300. A positioning roller a342 is rotatably connected between the mounting frames 340. The mounting frame 340 is provided to fix the position of the positioning roller a342 at the front end of the outer wall of the gantry 300. The driving motor b341 can drive the positioning roller a342 to rotate through the output shaft, so that the positioning roller a342 can move and convey the clamped stainless steel I-beam body 200. The driving motor b341 is fixed to the top end of the outer wall of the mounting frame 340. The bottom end of the driving motor b341 is fixedly connected to the upper end of the outer wall of the positioning roller a342 through the output shaft. A clamping frame b351 is arranged at the rear end of the inner wall of the gantry 300 at a position corresponding to the positioning roller a342. A positioning roller b352 is rotatably connected to the front end of the inner wall of the clamping frame b351. A telescopic cylinder b350 is fixed to the rear end of the outer wall of the gantry 300 at a position corresponding to the clamping frame b351. The output end of the telescopic cylinder b350 is fixedly connected to the rear end of the outer wall of the clamping frame b351. The telescopic cylinder b350 is provided to control the movement of the clamping frame b351 through the output end, so that the clamping frame b351 can cooperate with the positioning roller b352 to clamp the front and rear ends of the outer wall of the stainless steel I-beam body 200.

[0025] The usage process of the present utility model is as follows: First, the worker can place both ends of the stainless steel I-beam body 200 on two bottom rotating rollers 330 through mobile setting. Then, rotate the screw rod 320 so that the screw rod 320 drives the upper pressing plate 310 to move downward, making the bottom end of the upper pressing plate 310 tightly press against the top end of the outer wall of the stainless steel I-beam body 200. At the same time, before rotation, make the front of the stainless steel I-beam body 200 contact with the outer wall of the positioning roller a 342. After rotation, the worker can start the telescopic cylinder b 350 so that the telescopic cylinder b 350 drives the clamping frame b 351 and the positioning roller b 352 to tightly press against the rear end of the outer wall of the stainless steel I-beam body 200, thereby being able to cooperate with the positioning roller a 342 to limit the positions of the front and rear ends of the stainless steel I-beam body 200. After the limitation is completed, the worker can start the telescopic cylinder a 110 so that the telescopic cylinder a 110 drives the clamping frame a 120 and the pressing wheel 121 to move forward. At the same time, when the pressing wheel 121 tightly presses against the rear end of the outer wall of the stainless steel I-beam body 200 and continues to move forward, the worker can start the driving motor b 341 and the driving motor a 122, so that the driving motor b 341 drives the positioning roller a 342 to rotate, and the driving motor a 122 drives the pressing wheel 121 to rotate. Thus, the stainless steel I-beam body 200 can be moved left or right through the frictional force between the positioning roller a 342, the pressing wheel 121 and the outer wall of the stainless steel I-beam body 200. During the movement, as the telescopic cylinder a 110 continues to drive the clamping frame a 120 and the pressing wheel 121 to move, the stainless steel I-beam body 200 can be made complete. With multiple controls of the left and right movement of the stainless steel I-beam body 200, the stainless steel I-beam body 200 can be bent to the required angle. After completion, reset the device and take out this group of stainless steel I-beam bodies 200 for replacement.

[0026] The above are only the preferred embodiments of the present utility model. Any person skilled in the art may modify the present utility model by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present utility model falls within the scope of protection required by the present utility model.
