The opposite surfaces of the two adjustment rods 72 are fixedly connected to the adjustment plate 73, and the bottoms of the opposite surfaces of the two adjustment plates 73 are fixedly connected to the placement plate 10;

[0031] The top and bottom of the regulating plate 73 close to the regulating gas tank 71 are fixedly connected to the second spring 74, and the end of the second spring 74 away from the regulating plate 73 is fixedly connected to the side wall of the regulating gas tank 71;

[0032] The tops of the two adjusting plates 73 facing each other are fixedly connected with a fixing plate 8, and the inside of the fixing plate 8 is connected with a clamping assembly 9;

[0033] The clamping assembly 9 includes a threaded rod 91 threadedly connected to the interior of the fixing plate 8, and the bottom of the threaded rod 91 is rotatably connected to a clamping plate 92;

[0034] The rebound force of the second spring 74 is greater than the sum of the weights of the adjustment plate 73 , the placement plate 10 and the clamping assembly 9 .

[0035] When the workpiece is in the working state, the fixing plate 92 is fixed to the workbench 2 and the fixing plate 93 is fixed to the workbench 2. When the workpiece is in the working state, the fixing plate 92 is fixed to the workbench 2 and the fixing plate 93 is fixed to the workbench 2. When the workpiece is in the working state, the fixing plate 92 is fixed to the workbench 2 and the fixing plate 93 is fixed to the workbench 2. When the workpiece is in the working state, the fixing plate 92 is fixed to the workbench 2 and the fixing plate 93 is fixed to the workbench 2. When the workpiece is in the working state, the fixing plate 92 is fixed to the workbench 2 and the fixing plate 93 is fixed to the workbench 2.

[0036] Specifically, such as Figure 1-Figure 3 As shown, the bottom of the connecting plate 5 and the left and right sides of the stable base 13 are jointly provided with a protective component 6;

[0037] The protection assembly 6 includes connecting rods 61 fixedly connected to the bottom of the left and right sides of the connecting plate 5 and the stable base 13. The two sets of connecting rods 61 are hinged to the opposite surfaces of the protective plates 63. The inner side walls of the two sets of connecting rods 61 are fixedly connected to the first springs 62. The ends of the first springs 62 away from the connecting rods 61 are fixedly connected to the left and right sides of the straightening head 11 and the stable base 13.

[0038] The rebound force of the first spring 62 is greater than the sum of the gravity of the connecting rod 61 and the protective plate 63;

[0039] The stabilizing base 13 and the protection plate 63 are both provided with a limiting groove 14 , and the limiting groove 14 is arc-shaped.

[0040] By adopting the above technical solution, the operation of the hydraulic cylinder 4 drives the connecting plate 5 to rise and fall, and the connection plate 5 drives the straightening head 11 to rise and fall during the lifting process, which straightens the steel placed on the stable base 13. At the same time, the straightening head 11 drives the protective plate 63 to fall during the straightening process. The falling protective plate 63 has a protective effect on the two ends of the straightening position of the straightening head 11. As the straightening head 11 continues to fall, it drives the protective plate 63 to slide on the outer surface of the steel. During the sliding process of the protective plate 63, the first spring 62 is stretched and the connecting rod 61 is driven to move. The protective plate 63 is used to protect the outer surface of the steel during the sliding process, thereby improving the stability of the steel during the straightening process, and avoiding the straightening head 11 always pressing on the middle of the steel during the straightening process, resulting in deformation at both ends of the straightening position. It is beneficial to use the protective plate 63 to control the pressure on the outer surface of the steel, thereby improving the working efficiency of steel straightening.

[0041] Working principle: When in use, the steel to be straightened is placed on the stable base 13, and the two ends of the steel are placed on the placement plate 10. Then, the threaded rod 91 is rotated to drive the clamping plate 92 to stably clamp the two ends of the steel. After the steel is placed and clamped, the hydraulic cylinder 4 drives the connecting plate 5 to descend, and the descent of the connecting plate 5 drives the straightening head 11 to descend. The straightening head 11 is used to straighten the bent part of the steel. At the same time, the protective plate 63 is driven to descend during the descent of the connecting plate 5. The descent of the protective plate 63 has a protective effect on the two ends of the steel. As the straightening head 11 descends, the protective plate 63 drives the connecting rod 61 to stretch the first spring 62 to slide on the outer surface of the steel to stabilize the steel during the straightening process.

[0042] At the same time, when the size of the steel changes during the straightening process, the change in the size of the steel drives the placement plate 10 to squeeze the adjustment plate 73. The adjustment plate 73 is squeezed by the size of the steel and then squeezes the second spring 74 to slide. At the same time, the adjustment rod 72 drives the push plate 75 to slide in the adjustment gas tank 71 during the sliding process, thereby achieving the effect of synchronous adjustment of the steel during the straightening process, avoiding the situation in which the two ends of the steel are stably clamped due to size changes during the straightening process, resulting in the two ends being squeezed and damaged, which is beneficial to improving the safety of the steel straightening process.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
