The supporting frame 110 is substantially rectangular, and includes two opposite surfaces, one of which is a positioning surface 112, the other of which is an operating surface 114, and both the positioning surface 112 and the operating surface 114 are flat surfaces.
The supporting frame 110 is provided with a plurality of fixed wheels 120 which are used for matching with the straightening wheels 140 to straighten the steel bars together, the fixed wheels 120 are all positioned on one side of the positioning surface 112 far away from the operating surface 114, and each fixed wheel 120 can rotate around the axis of the fixed wheel 120. In this embodiment, the number of the fixed wheels 120 is three and the fixed wheels are arranged at intervals along the length direction of the supporting frame 110.
The support portion 131 and the adjustment portion 136 are each substantially cylindrical. The supporting portion 131 includes a supporting section 134 and a locking section 132 connected to each other, the supporting section 134 is rotatably installed in the supporting frame 110, and an end of the supporting section 134 away from the locking section 132 is connected to the adjusting portion 136. The locking section 132 extends out of the supporting frame 110 and is located on the side of the operating surface 114 away from the positioning surface 112. Further, the support section 134 and the locking section 132 are coaxially disposed, and the diameter of the support section 134 is larger than that of the locking section 132.
The axis of the adjusting part 136 is parallel to the axis of the supporting part 131 at an interval, and the distance between the two is determined according to actual requirements, and generally does not exceed one half of the radius of the supporting part 131, so as to facilitate the processing of the straightening shaft 130.

It should be noted that, in other embodiments, the locking member 150 may not be provided, and a certain damping is provided between the supporting portion 131 and the supporting frame 110, when the supporting portion 131 does not receive other acting force, it may be fixed relative to the supporting frame under the damping effect, and when the supporting portion 131 receives other acting force and the acting force is large enough, it may rotate against the damping effect.
The straightening wheels 140 may be rotatably mounted on the adjusting portion 136 in different manners as required, and in this embodiment, the straightening wheels 140 are mounted on the adjusting portion 136 through bearings to ensure the reliability and stability of the rotation. In other embodiments, the straightening wheel 140 can also be directly sleeved on the adjusting portion 136.
Furthermore, the end surface of the straightening wheel 140 close to the supporting frame 110 and the positioning surface 112 are arranged at intervals, so that friction between the straightening wheel 140 and the positioning surface 112 is avoided, and the resistance of the straightening wheel 140 during rotation is reduced.
In this embodiment, the number of the straightening wheels 140 is two, and the two straightening wheels 140 are located above the three fixed wheels 120 and are arranged at intervals along the length direction of the supporting frame 110. Furthermore, two straightening wheels 140 and three fixing wheels 120 are alternately arranged in sequence along the length direction of the supporting frame 110, and the two straightening wheels 140 and the three fixing wheels 120 are staggered with each other along the height direction of the supporting frame 110. The two straightening wheels 140 and the three fixed wheels 120 are provided with annular grooves used for being matched with the reinforcing steel bars, the bottoms of the annular grooves of the two straightening wheels 140 are located on the same straight line extending along the length direction of the support frame 110, the tops of the annular grooves of the three fixed wheels 120 are also located on the same straight line extending along the length direction of the support frame 110, and the annular grooves of the two straightening wheels 140 and the three fixed wheels 120 form a straightening channel used for straightening the reinforcing steel bars together. In other embodiments, the number of straightening wheels 140 may be other values, such as one or three.
It should be noted that the number of the straightening wheels 140 and the number of the straightening shafts 130 are related, and when the number of the straightening wheels 140 is two, the number of the straightening shafts 130 is also two, so as to correspond to and cooperate with the two straightening wheels 140 one by one. In other embodiments, when the number of the straightening wheels 140 is other values, the number of the straightening shafts 130 is changed, as long as the two satisfy a one-to-one correspondence relationship.
The working principle and the process of the reinforcing steel bar straightening device 100 are as follows:
when the steel bar is straightened, the nut is tightly propped against the operating surface 114 of the support frame 110, at the moment, the straightening shaft 130 is fixed relative to the support frame 110, and the position of the straightening wheel 140 is fixed;
when it is desired to adjust the position of straightening wheels 140 to change the size of the straightening channel to accommodate different size bars, the nut is rotated to release the operating surface 114 of the carriage 110, and the straightening shaft 130 can be rotated relative to the carriage 110. The user can cooperate with the transmission part 138 by a tool (such as a wrench, etc.), then screw the transmission part 138 to drive the support part 131 to rotate, thereby adjusting the position of the straightening wheels 140 to match the size of the straightening channel with the size of the steel bar to be straightened, and then rotate the nut to re-abut against the operation surface 114 of the supporting frame 110 to fix the straightening shaft 130 relative to the supporting frame 110. The whole adjusting process only needs to screw the nut and the transmission part 138, and the operation is convenient and quick.
The reinforcing steel bar straightening device 100 comprises a support frame 110, a straightening shaft 130 and a straightening wheel 140, wherein the straightening shaft 130 comprises a supporting part 131 and an adjusting part 136 which are connected with each other, the supporting part 131 is rotatably arranged on the support frame 110, the adjusting part 136 is eccentrically arranged relative to the supporting part 131, and the straightening wheel 140 is rotatably arranged on the adjusting part 136. When the supporting portion 131 rotates around its axis relative to the supporting frame 110, the adjusting portion 136 will also rotate along with the supporting portion, but because the adjusting portion 136 is eccentrically disposed relative to the supporting portion 131, that is, the axes of the two do not coincide, the adjusting portion 136 will not rotate around its axis, but rotate around the axis of the supporting portion 131, so that the position of the adjusting portion 136 can be adjusted, thereby adjusting the position of the straightening wheels 140 installed on the adjusting portion 136, the whole adjusting process only needs to rotate the supporting portion 131, the operation is convenient and fast, and the defects of the prior art are effectively remedied.
The embodiment also provides a steel bar straightening device which comprises the steel bar straightening device 100 and can conveniently and quickly adjust the position of the straightening wheels 140. In detail, the number of the reinforcing bar straightening devices 100 is two, one of the straightening wheels and the fixed wheel is arranged in the vertical direction, the other one of the straightening wheels and the fixed wheel is arranged in the front-rear direction, and the straightening channels of the two reinforcing bar straightening devices 100 extend in the left-right direction. This allows straightening from the reinforcement to be performed from different directions to improve the straightening effect on the reinforcement.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
