Description

Technical Field

[0001] This utility model belongs to the field of rebar straightening technology, and specifically relates to a rebar straightening device. Background Technology

[0002] The length of steel bars when they leave the factory is generally between one hundred and several hundred meters. For convenient transportation, they are wound into steel coils for transport. Before use, they are straightened by a steel bar straightening device and then cut into appropriate lengths. With existing straightening devices, the steel bars are cut directly after passing through the straightening device. However, sometimes some steel bars are bent to a large extent. After one straightening, they will bend again under the influence of elastic deformation, and then need to be reshaped, which affects efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a steel bar straightening device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this rebar straightening device to solve its technical problems is as follows: A rebar straightening device is provided, comprising a base plate, on which a first support plate is fixedly mounted. An array of drive wheels is rotatably mounted on the first support plate, each array comprising two vertically arranged drive wheels driven by a motor fixedly mounted behind the support plate. A second support plate is fixedly mounted on the base plate to one side of the first support plate, and the second support plate has two rows of vertical straightening wheels, staggered in position. A support platform is fixedly mounted on the base plate to one side of the second support plate, and the support platform has two rows of horizontal straightening wheels, staggered in position. A support rod is provided to one side of the support platform, and an outer ring is fixedly mounted on the support rod. An inner ring is located inside the outer ring, and several pressure sensors are fixedly mounted on the inner circumference of the outer ring. Springs are fixedly mounted on each pressure sensor, and the springs are fixedly mounted on the inner ring.

[0005] Furthermore, a base is provided on one side of the base plate, and a vertical rod is fixedly installed on the base.

[0006] Furthermore, the vertical rod has external threads, and the top plate is installed on the threaded vertical rod.

[0007] Furthermore, a groove is provided on one side of the base plate, and an electric track is provided in the groove. The movable part of the electric track is fixedly connected to the base.

[0008] Furthermore, rollers are fixedly installed at the bottom of the base.

[0009] Furthermore, the inner ring of the inner ring is an arc-shaped surface.

[0010] Furthermore, a retaining ring is provided on one side of the inner ring and fixedly installed on the inner ring of the outer ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a rebar straightening device in which the rebar passes sequentially through a vertical straightening wheel, a horizontal straightening wheel, and an inner ring under the drive of a drive wheel. When the rebar bends under elastic deformation, the pressure detected by the pressure sensor exceeds a threshold, controlling the motor of the drive wheel to synchronously reverse and retract the rebar for re-straightening. With this device, when the first straightening of the rebar is ineffective, the straightening can be corrected in time, facilitating a second straightening and making it more convenient to use.

[0012] 2. The steel bar straightening device of this utility model allows for easy placement of steel bar coils on a vertical rod during use, facilitating the extraction of the steel bars.

[0013] 3. A steel bar straightening device according to this utility model can clamp and fix the steel bar roll by rotating the top plate when the machine is stopped.

[0014] 4. In one example of this utility model, a steel bar straightening device uses an electric track. When the steel bar is retracted for re-straightening, the electric track moves synchronously, which can prevent the retracted part from bending.

[0015] 5. A steel bar straightening device according to this utility model example can facilitate the movement of the base by means of rollers.

[0016] 6. A steel bar straightening device according to this utility model can facilitate the movement of steel bars through its arc-shaped surface.

[0017] 7. A steel bar straightening device according to this utility model can conveniently limit the inner ring by using a retaining ring, so as to prevent the inner ring from shifting when the steel bar moves. Attached Figure Description
