[0022] The technical solutions in the present invention will be further described below in conjunction with the drawings and embodiments.

[0023] As Figure 1 shown in Figure 2 a steel bar straightening device is proposed in an embodiment of the present invention for straightening the steel bar 1, including:

[0024] A mounting plate 2 is provided with a mounting part 15 and a fixing part 16 on both sides respectively to form a mounting position for mounting the steel bar 1, and the mounting position has a limiting end and a straightening end;

[0025] A straightening head 3 is slidably arranged at the straightening end and corresponds to the bent part of the steel bar 1;

[0026] A telescopic member is arranged on the mounting plate 2 and is connected to the straightening head 3 for driving the straightening head 3 to move towards the bent part of the steel bar 1; and

[0027] A fixing member is arranged at the limiting end for fixing the steel bar 1.

[0028] In the embodiment of the present invention, a mounting part 15 and a fixing part 16 are respectively installed on both sides of the mounting plate 2, so that the mounting plate 2, the mounting part 15 and the fixing part 16 form a U-shaped structure, and the inside thereof is a mounting position for mounting the steel bar 1. The top of the mounting position is the straightening end, and the bottom is the limiting end. After the steel bar 1 enters the mounting position, the straight part of the steel bar 1 is at the limiting end, and the bent part of the steel bar 1 is at the straightening end, and the bent part of the steel bar 1 corresponds to the straightening head 3. Under the action of the telescopic member, the straightening head 3 is driven to move towards the bent part of the steel bar 1, so as to apply pressure to the bent part of the steel bar 1, so that the bent part of the steel bar 1 also fits on the mounting part 15, realizing the straightening of the steel bar 1; at the same time, under the action of the fixing member, the straight part of the steel bar 1 can be firmly fixed at the limiting end at the bottom of the mounting position, ensuring the stability of the straightening of the steel bar 1 and the quality. There is no need for manual effort to straighten the bent part of the steel bar 1, and only the whole device needs to be held, reducing the labor intensity and not requiring large-scale movements.

[0029] Based on the above solution, as Figure 1 shown in Figure 3As shown, the telescopic member includes a telescopic rod 4. A mounting seat 13 is provided on one side of the mounting plate 2. The telescopic rod 4 is fixedly arranged on the mounting seat 13. The mounting plate 2 is provided with a sliding groove 8. A driving block 14 connected to the correction head 3 is slidably arranged in the sliding groove 8. The telescopic end of the telescopic rod 4 passes through the mounting seat 13 and is connected to the driving block 14, so that the correction head 3 slides along the sliding groove 8. Specifically, when correcting the bent part of the steel bar 1, by starting the telescopic rod 4, the telescopic end of the telescopic rod 4 contracts, thereby driving the correction head 3 connected to the telescopic end to move towards the bent part of the steel bar 1, and gradually contacting and pressing the bent part of the steel bar 1 to straighten the bent part of the steel bar 1. Based on the correction effect, the above steps can be repeated multiple times, that is, the telescopic end of the telescopic rod 4 is used to drive the correction head 3 to press the bent part of the steel bar 1 multiple times to ensure the straightening quality. The above telescopic member can be any one of an electric cylinder, a hydraulic cylinder and an oil cylinder.

[0030] Based on the above solution, as Figure 1 with Figure 2 shown, the fixing member includes a fixing plate 5 at the limiting end, a limiting frame 9 passing through the mounting part 15 and connected to the fixing plate 5, and a threaded rod 12 fixedly arranged on the mounting part 15. The limiting frame 9 is sleeved on the threaded rod 12. The threaded rod 12 is threadedly connected with a threaded knob 10. The threaded knob 10 is rotatably arranged at the end of the limiting frame 9. Specifically, when fixing the straight part of the steel bar 1, in the initial state, there is a certain distance between the fixing plate 5 and the fixing part 16. When this gap is buckled to the straight part of the steel bar 1, by rotating the threaded knob 10, the threaded knob 10 moves on the threaded rod 12 and drives the limiting frame 9 connected thereto to move in the mounting part 15, so that the distance between the fixing plate 5 and the fixing part 16 gradually decreases and the straight part of the steel bar 1 is clamped and fixed. When fixing, it is necessary to ensure that the bent part of the steel bar 1 is at the top of the fixing plate 5 so that the bent part of the steel bar 1 corresponds to the correction head 3. Conversely, by reversing the threaded knob 10, the fixing plate 5 can be gradually separated from the fixing part 16, thereby releasing the limitation on the steel bar 1. Moreover, the distance between the fixing plate 5 and the fixing part 16 can be adjusted to limit and install steel bars 1 with different diameters, improving the applicability.

[0031] Specifically, limiting grooves 6 are provided on the side of the fixing plate 5 close to the steel bar 1 and on the side of the fixing part 16 close to the steel bar 1. The limiting grooves 6 are arc-shaped. Under the action of the limiting grooves 6, when fixing the steel bar 1, the stability can be improved, avoiding the lateral displacement of the steel bar 1 after fixing. And the limiting grooves 6 are arc-shaped, which better fits the shape of the steel bar 1, further ensuring the fixing stability. Moreover, a number of anti-slip lines are provided in the limiting grooves 6, which can increase the friction between the limiting grooves 6 and the steel bar 1 and improve the stability.

[0032] Specifically, as Figure 2As shown, a handle 11 is fixedly provided at one end of the threaded rod 12, which facilitates manual holding of the entire device by a person.

[0033] Specifically, as Figure 1-2 shown, a groove 7 corresponding to the correction head 3 is formed at one end of the fixing part 16 away from the limiting groove 6. When pressing and straightening the bent part of the steel bar 1, excessive pressing can be allowed to a certain extent, so that the bent part of the steel bar 1 can be bent in the opposite direction at a small angle to offset the stress of the steel bar 1 and improve the efficiency of correction.

[0034] In summary, through the action of the fixing member, the straight part of the steel bar 1 is first installed between the fixing plate 5 and the fixing part 16, and by rotating the threaded knob 10, the fixing plate 5 is moved closer to the fixing part 16 to clamp the straight part of the steel bar 1. Finally, by starting the telescopic rod 4, the telescopic end of the telescopic rod 4 drives the correction head 3 to press the bent part of the steel bar 1 multiple times to complete the correction. The entire correction work of the steel bar 1 does not require manual effort to correct the bent part of the steel bar 1, and only the whole device needs to be held, reducing the labor intensity and not requiring large-scale movements.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
