DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0022] In construction projects, steel bar straightening is an important process. Figures 1 to 4 A new type of steel bar straightening machine was demonstrated, which mainly includes two components: a straightening machine base and a retractable straightening rod.

[0023] Straightening the base part:

[0024] The straightening machine base of this machine is divided into a first straightening machine base 1 and a second straightening machine base 2, both of which have the same structure and are symmetrically designed. The first straightening machine base 1 is composed of a base body 11, and a slide groove 12 is provided at the upper end of the base body 11 for installing and sliding the storage straightening rod. A protruding block 14 and a mounting seat 5 are also provided at one end of the base body 11. The mounting seat 5 is located below the protruding block 14 and is used to fix and install the equipment.

[0025] The base body 11 of the second straightening machine base 2 is provided with a rotating part 6 adapted to the mounting seat 5 on the first straightening machine base 1. The rotating part 6 is cleverly placed in the clamping cavity between the protruding block 14 and the mounting seat 5. At the upper end of the rotating part 6, an angle adjustment handle 7 is provided, and its screw tube part passes through the protruding block 14 and is threadedly connected thereto. The user only needs to turn the angle adjustment handle 7 to drive the second straightening machine base 2 to rotate, thereby adjusting the angle between the second straightening machine base 2 and the first straightening machine base 1 to meet the needs of steel bar straightening at different angles.

[0026] The base 11, the protruding block 14 and the mounting base 5 are designed as one piece, and the cross section is in a "Y" shape, which is not only structurally stable, but also easy to install. The end surface of the mounting base 5 is provided with a drill rod installation position, and the drill rod can pass through this installation position to firmly fix the straightening machine on the construction site. In addition, the drill rod can also be inserted into the slide groove 12 of the base 11 to further enhance the stability of the equipment.

[0027] Retractable straightening rod part:

[0028] The retractable straightening rod is divided into a first retractable straightening rod 3 and a second retractable straightening rod 4, and the two have the same structure. Taking the first retractable straightening rod 3 as an example, it includes a slider 31 and a roller 34. The slider 31 is embedded in the slide groove 12 and can slide freely along the slide groove 12. The upper end of the slider 31 is provided with an embedding groove 33, and a rotatable rotating shaft 35 is connected in the groove. The rotating shaft 35 is fixed to the slider 31 by a fastener 36. The outer end of the rotating shaft 35 is provided with a roller 34, and the roller 34 is used to clamp the steel bar and straighten it.

[0029] The rollers 34 on the first straightening machine base 1 and the second straightening machine base 2 can clamp the steel bar together. By adjusting the position of the slider 31 in the slide groove 12, the contact point between the roller 34 and the steel bar can be changed, thereby adjusting the curvature of the steel bar. In addition, the outer end of the slider 31 is also connected to the pitch adjustment screw 37 through a T-key and a T-slot. The user can accurately change the position of the slider 31 and its upper roller 34 by rotating the pitch adjustment screw 37 to achieve an ideal straightening effect. Example

[0030] On the basis of the first embodiment, the present embodiment further optimizes the straightening machine. A limit groove 13 communicating with the slide groove 12 is added to the side wall of the seat body 11 of the first straightening machine seat 1. A limit block 32 adapted to the limit groove 13 is provided on the side wall of the slider 31. When the slider 31 slides in the slide groove 12, the limit block 32 will move synchronously in the limit groove 13, thereby limiting the up and down deflection of the slider 31, ensuring its stability and accuracy during the straightening process. This design not only improves the reliability of the equipment, but also reduces the difficulty of operation, making the steel bar straightening work more efficient and convenient.

[0031] When in use: fix the first straightening machine base 1 and the second straightening machine base 2 on the construction site through the rotating part 6 and the mounting base 5 to ensure that the structures of both are stable. Insert the sliders 31 of the first retractable straightening rod 3 and the second retractable straightening rod 4 into the slide grooves 12 of the first straightening machine base 1 and the second straightening machine base 2 respectively to ensure that the sliders 31 can slide freely.

[0032] The steel bar to be straightened is placed between the rollers 34 of the first straightening machine stand 1 and the second straightening machine stand 2 to ensure that the steel bar is clamped by the two rollers 34. According to the curvature of the steel bar, the position of the slider 31 in the chute 12 is manually moved to change the contact point between the roller 34 and the steel bar to perform preliminary curvature adjustment.

[0033] When more precise curvature adjustment is required, the pitch adjusting screw 37 is rotated. Since the outer end of the slider 31 is connected to the pitch adjusting screw 37 by means of a T-key and a T-slot, the rotation of the pitch adjusting screw 37 will drive the slider 31 and the roller 34 at its upper end to move precisely, thereby achieving an ideal straightening effect. According to the angle requirements of the steel bar, the angle adjustment handle 7 is rotated to drive the second straightening machine base 2 to rotate, thereby adjusting the angle between the second straightening machine base 2 and the first straightening machine base 1 to meet the requirements of steel bar straightening at different angles.

[0034] During operation, make sure the straightening machine is firmly fixed to avoid shaking or displacement during the straightening process. During the adjustment process, always observe the curvature changes of the steel bar to ensure that the adjustment achieves the expected effect. When operating the straightening machine, pay attention to safety to avoid pinching your hands or other safety accidents. This new type of steel bar straightening machine can be used to efficiently and accurately complete the straightening of steel bars.
