The embodiments of the present disclosure are not necessarily defined in all aspects including the present application. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any one of many ways, because the concepts and embodiments disclosed in the present application are not limited to any implementation. In addition, some aspects of the present application can be used alone or in any appropriate combination with other aspects of the present application.

[0022] Embodiment 1

[0023] As Figures 1-4 shown, the first embodiment of the present application provides a steel straightening device, which comprises a workbench 1, a conveying assembly 2 is installed on the top of the workbench 1, the conveying assembly 2 comprises a fixed plate 201, the two sides of the top of the workbench 1 are fixedly connected with the fixed plate 201, a first compression roller 202 is installed between the two fixed plates 201, a pressing assembly 3 is installed above the conveying assembly 2, the pressing assembly 3 and the conveying assembly 2 are used for straightening the steel, a limiting assembly 4 is installed at one end of the workbench 1, the limiting assembly 4 comprises a limiting box 401, a supporting plate 402, a limiting roller 403, a second motor 404, a screw rod 405, a threaded sleeve 406 and a sliding groove 407, the limiting box 401 is fixedly connected with the workbench 1, the screw rod 405 and the threaded sleeve 406 are both installed in the inner cavity of the limiting box 401, the second motor 404 is fixed on one side of the limiting box 401, the supporting plate 402 is located on the top of the limiting box 401, the number of the supporting plate 402 and the limiting roller 403 is both two, the limiting roller 403 is installed in the inner cavity of the supporting plate 402 through a bearing, the sliding groove 407 is opened on the top of the limiting box 401, the threads on both ends of the screw rod 405 are oppositely arranged, the number of the threaded sleeve 406 is two, and the threaded sleeve 406 is respectively sleeved on both ends of the screw rod 405 and is in threaded connection with the surface of the screw rod 405, the output shaft of the second motor 404 penetrates into the inner cavity of the limiting box 401 and is in transmission connection with the screw rod 405, and the end of the screw rod 405 away from the second motor 404 is movably connected with the inner wall of the limiting box 401 through a bearing.

[0024] As Figures 1-4As shown, by applying upward and downward forces to the conveying component 2 and the pressing component 3 respectively, a reverse bending moment is generated on the steel. Under the action of the moment, the original bending of the steel can be offset or reversed, so that it returns to a straight state and achieves the straightening effect. The limiting component 4 can limit the steel bar. The output shaft of the second motor 404 rotates forward to drive the screw 405 to rotate in the inner cavity of the limiting box 401. When the screw 405 rotates, it drives the two threaded sleeves 406 to move towards the middle. When the threaded sleeves 406 move, they drive the support plate 402 to move towards the middle along the inner cavity of the slide groove 407. The slide groove 407 can limit the movement trajectory of the threaded sleeves 406. At the same time, the two support plates 402 move towards the middle, driving the limiting roller 403 to move towards the middle, so that the steel bar passes through the gap between the two limiting rollers 403 and enters the surface of the first pressure roller 202. In this way, the limiting component 4 can limit the steel bar. When the output shaft of the second motor 404 reverses, the two support plates 402 gradually move away from each other.

[0025] Example 2

[0026] Reference Figure 1 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0027] In this embodiment, one end of the first pressure roller 202 is movably connected to a side fixing plate 201 via a bearing, and a transmission gear 205 and an idler wheel 206 are installed in the inner cavity of the other side fixing plate 201. The transmission gear 205 meshes with the idler wheel 206, and the idler wheel 206 is movably connected to the inner wall of the other side fixing plate 201 via a bearing.

[0028] The conveying assembly 2 also includes a first motor 203 and a reducer 204. Both the first motor 203 and the reducer 204 are fixedly connected to the other side fixed plate 201. The output shaft of the first motor 203 is connected to the input shaft of the reducer 204. The output shaft of the reducer 204 passes through the inner cavity of the other side fixed plate 201 and is connected to the transmission gear 205.

[0029] The other end of the first pressure roller 202 is fixedly connected to a transmission rod 207. The end of the transmission rod 207 away from the first pressure roller 202 passes through the inner cavity of the fixed plate 201 on the other side and is connected to the transmission gear 205.

[0030] like Figure 1 and 3As shown, the number of transmission gears 205 is even, and the number of idler gears 206 is odd. The idler gears 206 can adjust the direction of rotation of the transmission gears 205, so that the direction of rotation of each transmission gear 205 is consistent, thereby driving the first pressure roller 202 to rotate in the same direction. The output shaft of the first motor 203 rotates and drives the transmission gears 205 to rotate through the reducer 204. When the transmission gears 205 rotate, they drive the next transmission gear 205 to rotate through the idler gears 206, and so on, so that each transmission gear 205 can rotate. When the transmission gears 205 rotate, they drive the first pressure roller 202 to rotate through the transmission rod 207. When the first pressure roller 202 rotates, it can drive the steel strip to move, and under the pressure of the pressing component 3, it can straighten the steel strip.

[0031] Example 3

[0032] Reference Figure 1 and 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0033] In this embodiment, the pressing component 3 includes a bracket 301, a cylinder 302, a movable plate 303, and a second pressure roller 304. The pressing component 3 is installed on the top of both fixed plates 201, and the bracket 301 is fixedly connected to the fixed plate 201.

[0034] The cylinder 302 is fixed to the top of the bracket 301, the movable plate 303 is installed in the inner cavity of the bracket 301 and is slidably connected to the inner cavity of the bracket 301, both ends of the second pressure roller 304 are movably connected to the movable plates 303 on both sides through bearings, and the output end of the cylinder 302 passes through the bracket 301 and is fixedly connected to the movable plate 303.

[0035] like Figure 1 and 4 As shown, the gap between the second pressure roller 304 and the first pressure roller 202 can be adjusted by the cooperation of the bracket 301, the cylinder 302 and the movable plate 303, so that steel bars of different sizes can be straightened. The output end of the cylinder 302 extends and pushes the movable plate 303 to move downward along the inner cavity of the bracket 301. When the movable plate 303 moves, it drives the second pressure roller 304 to move downward, thereby adjusting the gap between the first pressure roller 202 and the second pressure roller 304.

[0036] In use, the output end of cylinder 302 extends and pushes movable plate 303 downward along the inner cavity of bracket 301. When movable plate 303 moves, it drives second pressure roller 304 downward, thereby adjusting the gap between first pressure roller 202 and second pressure roller 304. The limiting component 4 can limit the movement of the steel bar. The output shaft of second motor 404 rotates forward, driving screw 405 to rotate in the inner cavity of limiting box 401. When screw 405 rotates, it drives two threaded sleeves 406 to move towards the center. When threaded sleeves 406 move, they drive support plate 402 to move towards the center along the inner cavity of slide groove 407. Slide groove 407 can limit the movement trajectory of threaded sleeves 406. At the same time, the movement of two support plates 402 towards the center drives limiting roller 403 to move towards the center, passing the steel bar through the gap between the two limiting rollers 403. The gap between the first pressure roller 202 and the second pressure roller 304 is penetrated to limit the steel strip through the limiting component 4. The output shaft of the first motor 203 rotates and drives the transmission gear 205 to rotate through the reducer 204. When the transmission gear 205 rotates, it drives the next transmission gear 205 to rotate through the idler wheel 206, and so on, so that each transmission gear 205 can rotate. When the transmission gear 205 rotates, it drives the first pressure roller 202 to rotate through the transmission rod 207. When the first pressure roller 202 rotates, it can drive the steel strip to move. The first pressure roller 202 and the reducer 204 apply force to the steel strip at the same time, thereby generating a reverse bending torque on the steel. Under the action of the torque, the original bending of the steel can be offset or reversed, so that it returns to a straight state and achieves the straightening effect.

[0037] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.

[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
