[0002] Steel bars are widely used, mostly as semi-finished raw materials for various deep-processed steel products. In prestressed concrete components, such as high-strength prestressed concrete centrifugal piles, electric poles, viaduct piers, railway sleepers, etc., steel bars are widely used.

[0003] During processing, steel bars may bend due to problems in the processing procedure. During secondary processing of the steel bars, they need to be processed through a straightening mechanism to make them straight.

[0004] The existing straightening mechanism performs the straightening process by setting up multiple straightening disks, and the multiple straightening disks are respectively provided with threaded rods. In actual production, due to the different diameters of the steel bars, in order to control the degree of contact between the steel bars and the steel bars, it is necessary to adjust the rotation of each straightening disk one by one, which is inconvenient in actual operation. It is impossible to quickly adjust and then fine-tune the multiple straightening disks uniformly. In the process of straightening the steel bars, the straightened steel bars will be unloaded at the other end. However, manual support is required during the unloading process. The steel bars may generate high temperature due to deformation during the straightening process. Manual support may be accompanied by the risk of burns. Therefore, a straightening mechanism suitable for steel bars is proposed to solve the above problems. Utility Model Content

The moving seat 6 is slidably connected to the inner wall of the sliding seat 4. The inner wall of the sliding seat 4 is provided with a guide groove that fits the moving seat 6, so that the moving seat 6 can move back and forth on the inner wall of the sliding seat 4, and it itself will not rotate synchronously with the rotation of the threaded rod 5. The top of the outer wall of the moving seat 6 is fixedly connected with the straightening wheel 7. The straightening wheel 7 is a prior art, and a groove is provided on its surface. The steel rod passes through its groove, so that it is straightened by the straightening wheel 7.

[0033] Reference Figure 2-Figure 3The inner wall of the mechanical box 2 is provided with an adjustment component 8, which includes a guide column 81, which is fixedly connected to the top end of the left outer wall of the body 1. The surface of the guide column 81 penetrates and is slidably connected with a slider 82. The guide column 81 is provided to guide the position of the slider 82 to prevent the slider 82 from detaching from the outer wall of the guide column 81 during the movement. The right outer wall of the slider 82 is fixedly connected with a connecting block 83. A slide groove is provided on the left inner wall of the body 1. The connecting block 83 penetrates and is slidably connected to the inner wall of the slide groove of the body 1. By providing a slide groove on the left side of the body 1, the connecting block 83 can only move up and down on the inner wall of the slide groove of the body 1. Two sets of hinged rods 84 are hinged on the surface of the connecting block 83. The end of the hinged rod 84 away from the connecting block 83 is hinged with a connecting rod 85. The bottom end of the outer wall of the sliding seat 4 is fixedly connected to the top end of the outer wall of the connecting rod 85. During the up and down movement of the connecting block 83, the two sets of hinged The rod 84 moves synchronously, thereby pulling the connecting rods 85 on both sides and the sliding seat 4 at the top to move toward each other inside the mechanical box 2, thereby quickly adjusting the position of the straightening wheel 7, so that there is no need to rotate each set of threaded rods 5 separately to perform multiple rotation adjustments of the straightening wheel 7. The connecting rod 85 is slidably connected to the inner wall at the top of the body 1, and the inner wall of the slider 82 is elastically connected to the plug block 86 through a limit spring 87. One end of the limit spring 87 is fixedly connected to the surface of the plug block 86, and the other end of the limit spring 87 is fixedly connected to the inner side wall of the slider 82. The function of the limit spring 87 is to automatically reset the position of the plug block 86 after it is pulled outward. The plug block 86 penetrates and is slidably connected to the inner wall of the slider 82. The surface of the guide column 81 is provided with multiple groups of through holes, and the bottom end of the outer wall of the plug block 86 is plugged into the inner wall of the through hole. The plugging between the two fixes the slider 82 and the connecting block 83 at multiple positions after the inner wall of the mechanical box 2 is adjusted.

[0034] Reference Figure 1 and Figure 4 The cam 33 is provided with two groups, and the two groups of cam 33 are fixedly connected to the top of the outer wall of the right side of the body 1, and the sliding post 33 is slidably connected to the inner wall of the cam 33, and the bottom end of the inner wall of the cam 33 is elastically connected to the sliding post 33 through a return spring 32. One end of the return spring 32 is fixedly connected to the bottom end of the outer wall of the sliding post 33, and the other end of the return spring 32 is fixedly connected to the bottom end of the inner wall of the cam 33. The function of the return spring 32 is that when the steel rod falls on the surface of the blanking plate 34, it will drive the blanking plate 34 and the sliding post 33 to descend on the inner wall of the fixed column 31, and make the return spring 32 elastically compressed, so as to elastically support the blanking plate 34, and the top end of the outer wall of the sliding post 33 is fixedly connected to the blanking plate 34, and the blanking plate 34 is provided to place the steel rod after it is lowered, and there is no need to manually support the steel rod.

[0035] Working principle: First, put the steel rod from the left side of the mechanical box 2 into the multiple sets of straightening wheels 7, and push the movable seat 6 to move on the inner wall of the sliding seat 4 by rotating the threaded rod 5, so that the straightening wheel 7 contacts the steel rod for straightening. The guide groove on the inner wall of the sliding seat 4 ensures that the movable seat 6 does not rotate with the threaded rod 5 but only moves back and forth. At the same time, when the thickness difference of the steel rod is large, the plug block 86 can be pulled outward to make it disengage from the insertion into the through hole of the guide column 81, and the limit spring 87 can be elastically compressed. At this time, the slider 82 can be pulled to drive the connecting block 83 to move along the guide column 81. The movement of the connecting block 83 drives the hinged rod 84, and then pulls the connecting rod 85 and the top sliding seat 4 to move toward each other inside the mechanical box 2, and quickly adjusts the position of the straightening wheel 7. At this time, release the plug block 86 and it will be affected by the limit spring 87. The function of the plug block 86 is to fix the position of the slider 82 by plugging it into the through hole on the surface of the guide column 81.

[0036] After the steel bar is straightened, it falls to the blanking assembly 3 and falls on the blanking plate 34, driving the sliding column 33 to descend on the inner wall of the fixed column 31, compressing the return spring 32. The return spring 32 elastically supports the blanking plate 34, thereby supporting the steel bar through the blanking plate 34, and there is no need for manual lifting of the steel bar.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
