[0002] A straightening machine was designed to adapt to the straightening of pipes and bars of different sizes. The straightening rollers were equipped with a threaded shaft and a rotatable rotating table to enable the straightening rollers to have the functions of lifting and lowering and adjusting the angle. However, the above improvements also made the straightening rollers unstable and prone to shaking, resulting in the straightening of pipes and bars not meeting the standards.

[0003] Therefore, it is necessary to provide a metal tube and bar straightening machine locking device to solve the above problems. Utility Model Content

[0004] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a locking device for a metal tube and bar straightening machine to achieve the effect of improving stability.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0024] like Figure 1-4 As shown, the present application provides a locking device for a metal tube and rod straightening machine, comprising a base 1, a top platform 11 is arranged on the upper side of the base 1, and a plurality of guide shafts 12 are connected between the base 1 and the top platform 11.

[0025] Several support platforms 2 (only one group is shown in the figure) are arranged on the upper side of the base 1 and the lower side of the top platform 11. The two ends of the support platforms 2 are slidably connected to a guide shaft 12 respectively. The support platforms 2 on the upper side of the base 1 correspond to the support platforms 2 on the lower side of the top platform 11.

[0026] A rotating table 21 is rotatably provided on one side opposite to the support platform 2, and a supporting plate 22 is fixed on both sides of the rotating table 21 away from one end of the support platform 2. A straightening roller 23 is rotatably connected between the two supporting plates 22, and the circumference of the straightening roller 23 is a concave arc surface.

[0027] The top platform 11 and the base 1 are both rotatably connected with a threaded rod 13 corresponding to the position of the support platform 2, and one end of the threaded rod 13 is threadedly connected to the support platform 2. Locking telescopic rods 3 are arranged on both sides of the threaded rod 13. In this embodiment, the locking telescopic rod 3 is a hydraulic telescopic rod. The bottom of the locking telescopic rod 3 is fixed to the top platform 11 and the base 1 respectively.

[0028] The output end of the locking telescopic rod 3 extends to one side of the support platform 2 and is rotatably connected to a locking gear 31. A locking rod 32 is fixed to the side of the locking gear 31 away from the locking telescopic rod 3. A movable block 33 corresponding to the position of the locking rod 32 is provided on the side of the support platform 2 away from the threaded rod 13. A locking block 34 is fixed to the end of the locking rod 32 away from the locking gear 31 after passing through the support platform 2 and the movable block 33. A plurality of inclined locking blocks 35 are formed on the side of the locking block 34 close to the movable block 33. A locking groove 36 adapted to the locking block 35 is provided on the movable block 33.

[0029] A clamping groove 24 is formed on the circumferential edge of the rotating platform 21 , and a clamping plate 37 adapted to the clamping groove 24 is fixed to one side of the movable block 33 .

[0030] A driver 25 is provided on one side of the movable block 33. In the present embodiment, the driver 25 is a motor, which is fixed to the support platform 2. A driving gear 26 is fixed to the output end of the support platform 2 after passing through the support platform 2. The driving gear 26 is meshed with the locking gear 31.

[0031] It is understandable that motors for driving the threaded rod 13 are installed on the base 1 and the top platform 11, and the threaded rod 13 can drive the support platform 2 to move up and down when rotating.

[0032] Since the rotating table 21 can rotate, the direction of the straightening roller 23 can be adjusted, and the support table 2 can move up and down, so that the straightening machine can straighten pipes and bars of different sizes.

[0033] The driver 25 can drive the locking rod 32 to rotate via the driving gear 26 and the locking gear 31 .

[0034] Working status 1:

[0035] Since the locking block 35 is in the shape of an inclined surface, after the angle of the rotating table 21 is adjusted, when the locking rod 32 rotates toward one side, driving the locking block 35 and the locking groove 36 to continue to squeeze each other, since the end of the locking rod 32 away from the locking block 34 is supported by the locking gear 31 and the support table 2 and cannot move relative to the support table 2, the locking block 35 will push the movable block 33 to move toward the side close to the support table 2 through the locking groove 36. At this time, the locking block 34 will press the rotating table 21 through the clamping plate 37 and the clamping groove 24, making the rotating table 21 unable to rotate, thereby achieving the effect of fixing the rotating table 21.

[0036] Under normal circumstances, the locking telescopic rod 3 is in a relaxed state and does not affect the lifting and lowering of the support platform 2. After the height adjustment of the support platform 2 is completed, the locking telescopic rod 3 is retracted, so that the locking telescopic rod 3 pulls the support platform 2 as a whole through the locking rod 32, eliminating the thread gap between the support platform 2 and the threaded rod 13, thereby ensuring the stability of the pipe and rod during straightening.

[0037] This method is suitable for straightening tubes and bars with uniform diameters, so that the rotating table 21 remains locked, thereby preventing the rotating table 21 from shifting due to repeated lifting and lowering.

[0038] Working status 2:

[0039] When the locking rod 32 rotates in the opposite direction and drives the locking block 35 and the locking groove 36 to separate from each other by a certain distance, the clamping plate 37 will release the rotating platform 21 to facilitate the rotation of the rotating platform 21.

[0040] Under normal circumstances in this working state, the locking telescopic rod 3 is also in a relaxed state. After the height of the support platform 2 and the angle of the rotating table 21 are adjusted, the locking telescopic rod 3 contracts, and the locking telescopic rod 3 will lift the movable block 33 through the locking rod 32 and the locking block 34. At this time, it will drive the threaded rod 13, the support platform 2, the rotating table 21 and the clamping plate 37 to squeeze each other to eliminate the thread gap between the support platform 2 and the threaded rod 13, while preventing the rotating table 21 from rotating.

[0041] This method is suitable for straightening pipes and bars with non-uniform diameters, and is convenient for adjusting the angle and height of the straightening roller 23 at any time.
