[0058] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0059] like Figures 1 to 8 As shown, an embodiment of the utility model provides a steel bar bending device, including: an operating table 1; also including: a bending portion, which is arranged on the operating table 1; an adjusting portion, which is connected to the bending portion and cooperates with the bending portion to adjust the bending radius of the steel bar; a clamping portion, which is arranged on the operating table 1; a clamping adjustment member, which is arranged on the operating table 1 and cooperates with the adjusting portion to clamp the steel bar in a suitable position.

[0060] In the embodiment of the utility model, by providing an adjustment part, the bending radius can be changed during bending through the adjustment part, so that the device can meet bending requirements of different radii, thereby being suitable for different work scenes; by providing a clamping part, unstable placement of the steel bars during bending can be avoided to avoid operational risks.

[0061] like Figures 1 to 8 As shown, the bending portion includes: a first movable groove 201, which is opened at the upper end of the operating table 1; a rotating disk 2, which is arranged in the first movable groove 201; a bending rod 205, which is arranged on the rotating disk 2, and the axis is in the same straight line as the axis of the rotating disk 2; a first installation groove 206, which is opened on the rotating disk 2; a first limiting rod 207, which is inserted into the first installation groove 206; a first motor 208, which is arranged at the bottom end of the operating table 1, and the output end is connected to the rotating disk 2.

[0062] In the embodiment of the present utility model, Figure 1 As shown, the steel bar is placed between the first limit rod 207 and the bending rod 205 shown; by starting the first motor 208 to rotate, the rotating disk 2 is driven to rotate along its own axis, thereby driving the first limit rod 207 to rotate. When the first limit rod 207 rotates and fits on the steel bar, it rotates so that the first limit rod 207 applies force to the steel bar, causing the steel bar to bend around the bending rod 205, so that the bending radius of the steel bar is the same as the radius of the bending rod 205 shown.

[0063] Among them, it is more convenient to determine the bending angle of the steel bar by controlling the starting time of the first motor 208; and the first mounting groove 206 is provided with several groups, which are opened outward along the radius of the rotating disk 2. Normally, the first limit rod 207 is inserted in the first mounting groove 206 away from the center of the rotating disk 2. At this time, according to the lever principle, it is more labor-saving when bending, thereby saving electricity; but if the steel bar to be processed is shorter, the first limit rod 207 cannot touch the steel bar when rotating, and the first limit rod 207 needs to be inserted in a suitable first mounting groove 206 close to the center of the rotating disk 2; supporting square rods 101 are provided at the four corners of the bottom end of the operating table 1 to support the operating table 1.

[0064] like Figures 1 to 8 As shown, the adjusting part includes: a first placement ring groove 202, which is opened on the rotating disk 2, and the axis of the first placement ring groove 202 is in the same straight line as the axis of the rotating disk 2; the first placement ring groove 202 is provided with a plurality of groups, and the plurality of groups of the first placement ring grooves 202 are opened outward along the radius of the rotating disk 2; a first spring 203, one end of which is connected to the bottom end of the first placement ring groove 202; a bending cylinder 204, which slides in the first placement ring groove 202, and the bottom end is connected to the other end of the first spring 203; a clamping piece, which is arranged on the bending cylinder 204 to control the lifting and lowering of the bending cylinder 204.

[0065] In the embodiment of the utility model, in order to change the bending radius of the steel bar, it is necessary to change the radius of the steel bar around the bending member; by moving the clamping member, the clamping member is no longer acting on the bending cylinder 204, so that the contracted first spring 203 bounces upward, driving the bending cylinder 204 to move upward along the first placement ring groove 202, at this time, the steel bar is placed against the bending cylinder 204, and when bending, the steel bar will bend along the bending cylinder 204, so that the bending radius is the same as the radius of the bending cylinder 204;

[0066] Among them, several groups of first placement ring grooves 202 are provided, and thus several groups of bending cylinders 204 are also provided. Different bending cylinders 204 are arranged in layers, and the axes are on the same straight line, and the radii are different. Therefore, when the steel bar needs to be bent into a specified bending radius, the corresponding clamping part is moved to make the corresponding bending cylinder 204 bounce up, and the steel bar is limitedly bent.

[0067] like Figures 1 to 8 As shown, the clamping member includes: a second movable groove 302, which is opened at the top of the bending cylinder 204; a movable plate 303, which slides in the second movable groove 302; a second spring 304, one end of which is connected to the movable plate 303, and the other end is connected to the inner wall of the second movable groove 302; a connecting hole 307, which is opened on the bending cylinder 204; a clamping rod 305, one end of which is connected to the movable plate 303, and the other end is passed through the connecting hole 307; a first clamping groove 301, which is opened on the inner wall of the first placement ring groove 202 and cooperates with the clamping rod 305; a pushing plate 306, which is arranged on the movable plate 303.

[0068] In the embodiment of the utility model, first, the clamping rod 305 is clamped in the first clamping groove 301, so that the first spring 203 contracts and the bending cylinder 204 is in the first placement ring groove 202, thereby not affecting the placement of the steel bar; when the bending cylinder 204 needs to be specified to pop up upward, the pushing plate 306 is manually pushed to move toward the axis of the rotating disk 2, thereby driving the movable plate 303 to move toward the axis of the rotating disk 2. At this time, the second spring 304 extends and drives the clamping rod 305 to disengage from the first spring 203. The first spring 203 is pushed upwards to eject the corresponding bending cylinder 204. When the bending cylinder 204 is no longer needed, the bending cylinder 204 is pressed downwards by one hand and the pushing plate 306 is pushed by the other hand to shrink the clamping rod 305. When the bending cylinder 204 moves to the position corresponding to the first clamping groove 301, the pushing plate 306 is released to push the second spring 304 to rebound and the clamping rod 305 is clamped into the first clamping groove 301, thereby resetting the bending cylinder 204.

[0069] like Figures 1 to 8As shown, the clamping part includes: a second placement groove 401, which is opened on the operating table 1; a placement plate 503, which slides on the second placement groove 401; a fixed clamp block 502, which is arranged at the top of the placement plate 503; and a clamping drive member, which is arranged at the top of the placement plate 503 and away from the side of the fixed clamp block 502.

[0070] like Figures 1 to 8 As shown, the clamping drive component includes: a fixed plate 501, which is arranged on the placement plate 503; a second threaded rod 505, which is passed through the fixed plate 501 and is threadedly connected to the fixed plate 501; a movable clamping block 504, which is connected to the other end of the second threaded rod 505 and slides on the placement plate 503; a second limiting rod 506, one end of which is connected to the movable clamping block, and the other end of which is passed through the fixed plate 501; and a crank 507, which is connected to the other end of the second threaded rod 505.

[0071] In the embodiment of the utility model, the steel bar is placed on the placement plate 503 and is between the fixed clamp block 502 and the movable clamp block 504. The second threaded rod 505 is driven to rotate by manually turning the crank 507, so that the second threaded rod 505 moves back and forth on the fixed plate 501. The second threaded rod 505 drives the movable clamp block 504 to move along the placement plate 503 toward the fixed clamp block 502, thereby clamping the steel bar to prevent the steel bar from escaping from the device during bending, thereby creating a work risk.

[0072] like Figures 1 to 8 As shown, the clamping adjustment member includes: a third placement groove 405, which is opened at the bottom end of the second placement groove 401; a second motor 402, which is arranged in the third placement groove 405; a first threaded rod 403, one end of which is connected to the output end of the second motor 402, and the other end is rotatably connected to the inner wall of the third placement groove 405; a threaded sleeve 404, which is sleeved on the first threaded rod 403, and the top end is connected to the placement plate 503.

[0073] In the embodiment of the utility model, when clamping the steel bar, it is necessary to make one side of the steel bar fit on the corresponding bending cylinder 204 to facilitate bending. Since the radii of the bending cylinder 204 are different, the clamping part that needs to clamp the steel bar can also change with the change of the radius of the bending cylinder 204; by starting the second motor 402, the first threaded rod 403 is driven to rotate, thereby driving the threaded sleeve 404 to move along the first threaded rod 403, thereby driving the placement plate 503 to move, so that the placement plate 503 drives the clamped steel bar to move left and right to a suitable position.

[0074] Working principle: the steel bar is placed on the placement plate 503, and then the crank 507 is manually turned to drive the second threaded rod 505 to rotate, so that the second threaded rod 505 moves back and forth on the fixed plate 501, and the second threaded rod 505 drives the movable clamping block 504 to move along the placement plate 503 toward the fixed clamping block 502, so as to clamp the steel bar, and by starting the second motor 402, the first threaded rod 403 is driven to rotate, thereby driving the threaded sleeve 404 to move along the first threaded rod 403, thereby driving the placement plate 503 to move, so that the placement plate 503 drives the clamped steel bar to move left and right to fit on the bending cylinder 204; the first motor 208 is started to rotate, driving the rotating disk 2 to rotate along its own axis, thereby driving the first limiting rod 207 to rotate, and when the first limiting rod 207 rotates and fits on the steel bar, it rotates, so that the first limiting rod 207 applies force to the steel bar, so that the steel bar bends around the bending cylinder 204, so that the bending radius of the steel bar bending is the same as the radius of the bending cylinder 204.

[0075] When replacing a different bending cylinder 204, the pushing plate 306 is manually pushed to move toward the axis of the rotating disk 2, thereby driving the movable plate 303 to move toward the axis of the rotating disk 2. At this time, the second spring 304 is extended and drives the clamping rod 305 to disengage from the first clamping groove 301, so that the first spring 203 bounces upward, driving the corresponding bending cylinder 204 to pop out; when the bending cylinder 204 is no longer needed, the bending cylinder 204 is pressed downward by one hand and the pushing plate 306 is pushed by the other hand to shrink the clamping rod 305. When the bending cylinder 204 moves to the position corresponding to the first clamping groove 301, the pushing plate 306 is released to make the second spring 304 rebound, and the clamping rod 305 is clamped into the first clamping groove 301, thereby resetting the bending cylinder 204.

[0076] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
