Description

Technical Field

[0001] This utility model relates to the field of steel plates, and more specifically, to a steel plate bending device for steel structure columns. Background Technology

[0002] Steel plates are flat steel products made by pouring molten steel, cooling, and pressing. Steel plates are classified into hot-rolled and cold-rolled according to the rolling process. Steel plate bending machines are used in the production preparation area of ​​steel rolling mills to make ultra-fast cold guide channels in the three-way zone. In reality, a large number of steel plates with different specifications and curvatures are needed.

[0003] In related technologies, to address the problems that existing steel plate bending machines, due to their inherent design characteristics, are mostly fixed structures, making it inconvenient to disassemble and assemble the bent steel plates, and that the pressure blocks are prone to shifting during the bending process, thus failing to meet the diverse usage requirements of current steel plate bending machines, patent CN215657173U provides a steel plate disassembly device for a steel plate bending machine. This steel plate disassembly device guides the movement direction of the second forming column through the complementary action between the support slider and the slide groove, thereby effectively preventing the second forming column from shifting during the bending process of the steel plate.

[0004] In the actual construction of steel structure columns, steel plates often need to be bent to meet specific building requirements. However, during the bending process, the steel plates are prone to warping. At the same time, it is inconvenient to position the plates during installation, which can easily lead to deviations in the bending position, reducing the bending effect. Furthermore, manual operation is cumbersome and inefficient. Therefore, we propose a steel plate bending device for steel structure columns. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a steel plate bending device for steel structure columns, which aims to improve the technical problems of steel plate warping during bending, inconvenience in positioning the plate during installation, deviation in bending position, reduced bending effect, and cumbersome manual operation with low work efficiency.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a steel plate bending device for steel structure columns, comprising: a base plate, a motor, and a threaded rod. A mounting frame is fixedly installed on the top of the base plate via a support frame. A cam is rotatably mounted inside the mounting frame. A linkage rod cooperating with the cam is movably mounted on the inner side of the mounting frame via a sliding rod. A spring is sleeved on the outer side of the sliding rod. A mounting plate is fixedly installed at the bottom of the linkage rod. An extrusion block is fixedly installed at the bottom of the mounting plate. A worktable is slidably mounted on the outer side of the support frame via a mounting sleeve. A movable plate is threaded onto the rear end of the worktable. A connecting rod extending to the mounting sleeve is fixedly installed on the inner side of the movable plate. A bearing platform is fixedly installed on the top of the worktable. A forming block corresponding to the extrusion block is limited and installed on the inner side of the bearing platform.

[0008] Preferably, the motor is fixedly mounted on one side of the mounting frame, and the output end of the motor is fixedly connected to the cam. A support plate for mounting the motor is fixedly mounted on one side of the mounting frame.

[0009] By adopting the above technical solution, during the downward movement of the mounting plate, the linkage rod can move along the outside of the sliding rod and compress the spring. The mounting plate can then be easily moved upward by the spring's rebound.

[0010] Preferably, a side plate is fixedly installed on the outer side of the mounting plate, a movable rod is fixedly installed on the top of the side plate, a shrink sleeve is fixedly installed on the top of the support frame, and the top end of the movable rod extends into the interior of the shrink sleeve.

[0011] By adopting the above technical solution, the top of the movable rod can move inside the shrink sleeve during the movement of the mounting plate, making the mounting plate more stable during the movement.

[0012] Preferably, a threaded rod is rotatably mounted on the rear end of the workbench, a threaded sleeve is fixedly mounted on the movable plate, the threaded rod is located inside the threaded sleeve and is threadedly engaged, a swivel plate is fixedly mounted on the outer end of the threaded rod, and a docking hole is provided on the support frame to engage with the docking rod.

[0013] By adopting the above technical solution, the threaded rod can be rotated at the rear end of the worktable by rotating the plum blossom disc. The threaded sleeve and the threaded rod are threaded together, so that the mounting sleeve can be limited when it slides along the support frame to a suitable position.

[0014] Preferably, a limiting block is fixedly installed on the outer side of the molding block, and the support platform and the molding block are slidably installed together via the limiting block.

[0015] By adopting the above technical solution, the limiting block installed on the outside of the forming block can be installed on the inside of the support platform.

[0016] Preferably, the support platform and the molding block are fixed together by a fixing knob, and the molding block is provided with a limiting hole that cooperates with the fixing knob.

[0017] By adopting the above technical solution, the limiting block installed on the outside of the forming block can be installed on the inside of the support platform. The limiting block limits the forming block, and different specifications of forming blocks can be replaced for bending operations during use.

[0018] The beneficial effects of this utility model are:

[0019] 1. This application utilizes a linkage rod, cam, mounting plate, extrusion block, and forming block in a coordinated manner. By controlling the rotation of the motor, the cam installed inside the mounting frame rotates, extruding pressure on the top of the linkage rod. This causes the linkage rod to slide along the inner side of the mounting frame, allowing the extrusion block to move downwards and extrude pressure on the upper limit steel plate of the forming block, bending the steel plate. Simultaneously, as the mounting plate moves downwards, the linkage rod moves along the outer side of the sliding rod, compressing the spring. The spring's rebound allows the mounting plate to move upwards easily, facilitating a return operation.

[0020] 2. This application, through the mutual cooperation between the connecting rod, connecting hole, movable plate and forming block, allows the threaded rod to rotate at the rear end of the worktable by rotating the plum blossom disc. The threaded sleeve and the threaded rod are threaded together, thereby limiting the installation sleeve when it slides along the support frame to the appropriate position. The limiting block installed on the outside of the forming block can be installed on the inside of the bearing platform to limit the forming block. During use, forming blocks of different specifications can be replaced for bending operations. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Example, refer to Figures 1-4A steel plate bending device for steel structure columns includes a base plate 1, a motor 2, and a threaded rod 3. A mounting frame 104 is fixedly mounted on the top of the base plate 1 via a support frame 101. A cam 201 is rotatably mounted inside the mounting frame 104. A linkage rod 202, cooperating with the cam 201, is movably mounted on the inner side of the mounting frame 104 via a sliding rod 209. A spring 210 is sleeved on the outer side of the sliding rod 209. A mounting plate 203 is fixedly mounted on the bottom of the linkage rod 202. A pressing block 208 is fixedly mounted on the bottom of the mounting plate 203. The outer side of the support frame 101 is connected via a threaded rod 3. A worktable 103 is slidably mounted on the sleeve 102. A movable plate 301 is threaded onto the rear end of the worktable 103. A connecting rod 304 extending to the mounting sleeve 102 is fixedly mounted on the inner side of the movable plate 301. A support platform 306 is fixedly mounted on the top of the worktable 103. A forming block 307 corresponding to the extrusion block 208 is fixedly mounted on the inner side of the support platform 306. The motor 2 is fixedly mounted on one side of the mounting frame 104, and the output end of the motor 2 is fixedly connected to the cam 201. A support plate 207 for mounting the motor 2 is fixedly mounted on one side of the mounting frame 104.

[0029] Furthermore, a side plate 204 is fixedly installed on the outer side of the mounting plate 203, a movable rod 205 is fixedly installed on the top of the side plate 204, a shrink sleeve 206 is fixedly installed on the top of the support frame 101, the top end of the movable rod 205 extends into the interior of the shrink sleeve 206, a threaded rod 3 is rotatably installed on the rear end of the worktable 103, a threaded sleeve 302 is fixedly installed on the movable plate 301, the threaded rod 3 is located inside the threaded sleeve 302 and is threadedly engaged, a swivel plate 303 is fixedly installed on the outer end of the threaded rod 3, and a docking hole 305 is provided on the support frame 101 to engage with the docking rod 304.

[0030] It should be noted that: by controlling the rotation of the motor 2, the cam 201 installed inside the mounting frame 104 can be rotated. The cam 201 presses the top of the linkage rod 202, so that the linkage rod 202 can slide along the inner side of the mounting frame 104, thereby causing the extrusion block 208 to move downward and extrude the steel plate at the upper limit of the forming block 307, thus bending the steel plate.

[0031] Reference Figures 3-4 Furthermore, a limiting block 308 is fixedly installed on the outer side of the molding block 307, and the support platform 306 and the molding block 307 are slidably installed through the limiting block 308. The support platform 306 and the molding block 307 are limited and fixed through a fixing knob 309, and the molding block 307 is provided with a limiting hole that cooperates with the fixing knob 309.

[0032] It should be noted that: by threading the threaded sleeve 302 and the threaded rod 3, the mounting sleeve 102 can be limited when it slides along the support frame 101 to a suitable position. The limiting block 308 installed on the outside of the forming block 307 can be installed on the inside of the bearing platform 306. The limiting block 308 limits the forming block 307. During use, different specifications of forming blocks 307 can be replaced for bending operations.

[0033] The working principle of this steel plate bending device for steel structure columns is as follows: The rotation of the motor 2 drives the cam 201 installed inside the mounting frame 104 to rotate. The cam 201 presses the top of the linkage rod 202, causing the linkage rod 202 to slide along the inner side of the mounting frame 104. This allows the pressing block 208 to move downwards, pressing the steel plate at the upper limit of the forming block 307 and bending the steel plate. Simultaneously, as the mounting plate 203 moves downwards, the linkage rod 202 moves along the outer side of the sliding rod 209, pressing the spring 210. The rebound effect of 210 allows the mounting plate 203 to move upward easily, thus facilitating the restoration operation. By rotating the plum blossom disc 303, the threaded rod 3 can rotate at the rear end of the worktable 103. Through the threaded engagement between the threaded sleeve 302 and the threaded rod 3, the mounting sleeve 102 can slide along the support frame 101 to a suitable position and be limited. The limiting block 308 installed on the outside of the forming block 307 can be installed on the inside of the bearing platform 306, and the limiting block 308 limits the forming block 307. During use, different specifications of forming blocks 307 can be replaced for bending operations.

[0034] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
