Description

Technical Field

[0001] This utility model relates to the technical field of hot-rolled steel equipment, and in particular to an auxiliary device for biting into a straightening machine. Background Technology

[0002] During the cooling process on a cooling bed, uneven shrinkage of structural steel can easily cause head warping (curving) or central arching deformation. Traditional straightening machines rely solely on a single roller conveyor at the inlet, which presents the following problems:

[0003] 1. Difficulty in front-end biting: The upturned steel section cannot be effectively gripped by the active roller of the straightening machine, requiring manual intervention and adjustment, which is inefficient and poses safety hazards;

[0004] 2. Deformation in the middle causes blockage: After the front end is flattened, the middle and rear parts will lift up, which will cause the steel sections to "stack" during roller conveying and block the conveyor line;

[0005] 3. Insufficient automation: Existing auxiliary equipment cannot automatically detect the upturned steel section, nor can it automatically adjust the pressing device based on the upturned height.

[0006] Some companies have attempted to add a single set of pressure rollers before the straightening machine, but this only addresses the front-end warping and cannot handle the deformation in the middle. Furthermore, after the front warping is pressed down, the middle and rear ends warp up, causing the warped portion to detach from the transport rollers, reducing the transport's gripping capacity. Simultaneously, when the rear warps up, the next steel section will pass over the rollers and under the warped section, causing a "steel stacking" phenomenon and clogging the transport rollers. Moreover, the pressing device cannot automatically adjust based on the warping height. Therefore, there is an urgent need for an auxiliary device that can achieve dual-stage flattening and adaptive adjustment. Utility Model Content

[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1 and Figure 2 and Figure 3 As shown, a biting auxiliary device for a straightening machine includes a first leveling component 1, a second leveling component 2, and a conveying component 3. The first leveling component 1 and the second leveling component 2 are movably mounted on the conveying component 3. The first leveling component 1 and the second leveling component 2 have the same structural shape.

[0033] The conveying assembly 3 includes a first crossbeam 31, a second crossbeam 32, a first conveying roller 33, and a second conveying roller 34. The first crossbeam 31 and the second crossbeam 32 are arranged side by side. The first conveying roller 33 is rotatably mounted on the first crossbeam 31 and the second crossbeam 32 and is located between the first crossbeam 31 and the second crossbeam 32. The second conveying roller 34 is rotatably mounted on the first crossbeam 31 and the second crossbeam 32 and is located between the first crossbeam 31 and the second crossbeam 32. The first conveying roller 33 and the second conveying roller 34 rotate together to convey the steel section 4.

[0034] The first conveying roller 33 is connected to the drive end of the first motor 37, and the second conveying roller 34 is connected to the drive end of the second motor 38. The first motor 37 and the second motor 38 are mounted on the ground or other equipment. The first motor 37 drives the first conveying roller 33 to rotate, and the second motor 38 drives the second conveying roller 34 to rotate.

[0035] The first leveling assembly 1 includes a first support 11, a first hydraulic cylinder 13, a first suspension plate 15, and a first pressure roller 17. The first support 11 is movably mounted on the first crossbeam 31 and the second crossbeam 32. The first hydraulic cylinder 13 is mounted on the first support 11. The first suspension plate 15 is connected to the drive end of the first hydraulic cylinder 13. The first pressure roller 17 is rotatably mounted on the first suspension plate 15. The first conveying roller 33 is located on the moving path of the first pressure roller 17.

[0036] In the initial state, the first conveying roller 33 conveys the steel section 4, the first hydraulic cylinder 13 drives the first suspension plate 15 to descend to a set height, and the first pressure roller 17 on the first suspension plate 15 also descends to a set height. In this way, the first pressure roller 17 presses on the front part of the steel section 4 in the direction of movement, and the upturned part of the steel section 4 is flattened. The upturned part of the steel section 4 is flattened and directly enters the second leveling component 2. The steel section 4 moves out from between the first conveying roller 33 and the first pressure roller 17. The first pressure roller 17 makes rolling contact with the steel section 4. The first pressure roller 17 will rotate when the steel section 4 moves.

[0037] The second leveling assembly 2 includes a second support 22, a second hydraulic cylinder 24, a second suspension plate 26, and a second pressure roller 28. The second support 22 is movably mounted on the first crossbeam 31 and the second crossbeam 32. The second hydraulic cylinder 24 is mounted on the second support 22. The second suspension plate 26 is connected to the drive end of the second hydraulic cylinder 24. The second pressure roller 28 is rotatably mounted on the second suspension plate 26. The second conveying roller 34 is located on the moving path of the second pressure roller 28.

[0038] In the initial state, the steel section 4 is first conveyed by the first conveying roller 33, and then the steel section 4 overlaps the second conveying roller 34. The second hydraulic cylinder 24 drives the second suspension plate 26 to descend to a set height. Then the second pressure roller 28 descends to a set height along with the second suspension plate 26, so that the second pressure roller 28 presses on the leveling part of the steel section 4. The front part of the steel section 4 exits from the second pressure roller 28 and the second conveying roller 34, and then the leveled steel section 4 enters the straightening machine 5 straight.

[0039] The descent height of the first pressure roller 17 and the second pressure roller 28 can be adjusted according to the thickness of the steel section 4. After the first pressure roller 17 and the first conveying roller 33 jointly level the steel section 4, the steel section 4 enters between the second pressure roller 28 and the second conveying roller 34. In this way, the front part of the steel section 4 will no longer be raised. When the first pressure roller 17 and the first conveying roller 33 jointly level the steel section 4, the front end of the steel section 4 can enter the straightening machine 5 straight.

[0040] After the steel section 4 is leveled, the first hydraulic cylinder 13 drives the first suspension plate 15 to rise and reset, and the first pressure roller 17 also rises and resets. The second hydraulic cylinder 24 drives the second suspension plate 26 to rise and reset, and the second pressure roller 28 also rises and resets.

[0041] A first annular groove 331 is provided on the outer periphery of the first conveying roller 33, and a second annular groove 342 is provided on the outer periphery of the second conveying roller 34. The first annular groove 331 and the second annular groove 342 are located on the same straight line, and one side of the steel section 4 is rolled and stuck in the first annular groove 331 and the second annular groove 342.

[0042] The conveying assembly 3 also includes multiple auxiliary rollers 35, which are rotatably mounted on the first crossbeam 31 and the second crossbeam 32. Each auxiliary roller 35 has a third annular groove 353. The auxiliary rollers 35 are used to support the steel section 4. The third annular groove 353 is on the same straight line as the first annular groove 331 and the second annular groove 342. In this way, one side of the steel section 4 can move linearly within the first annular groove 331, the second annular groove 342 and the third annular groove 353, and the first pressure roller 17 can also prevent it from deforming under pressure.

[0043] According to the length of the steel section 4, the first leveling component 1 and the second leveling component 2 are moved so that the first pressure roller 17 and the second pressure roller 28 correspond to the two auxiliary rollers 35 at different positions. That is, the first pressure roller 17 and the second pressure roller 28, together with the auxiliary rollers 35, level the steel section 4.

[0044] The first leveling assembly 1 also includes a first clamping plate 131 and a second clamping plate 132. The first clamping plate 131 and the second clamping plate 132 are disposed on the first suspension plate 15. The first clamping plate 131 and the second clamping plate 132 together clamp the driving end of the first hydraulic cylinder 13. In this way, when the first hydraulic cylinder 13 drives the first suspension plate 15, the first suspension plate 15 can maintain a balanced rise or fall, so that the first pressure roller 17 can press flatly on the steel profile 4.

[0045] like Figure 2 and Figure 3 and Figure 4 As shown, the first clamping plate 131 is provided with a first clamping groove 133, and the second clamping plate 132 is provided with a second clamping groove 134. The driving end of the first hydraulic cylinder 13 is engaged in the first clamping groove 133 and the second clamping groove 134. In this example, the driving end of the first hydraulic cylinder 13 is provided with a connecting column 12. The two ends of the connecting column 12 are respectively connected to the driving end of the first hydraulic cylinder 13 and the first suspension plate 15. The connecting column 12 is engaged in the first clamping groove 133 and the second clamping groove 134, so that the connecting column 12 will not be offset. The driving end of the second hydraulic cylinder 24 is provided with another connecting column 12.

[0046] The first leveling assembly 1 also includes a first side plate 135 and a second side plate 136. The first side plate 135 and the second side plate 136 are disposed on the first suspension plate 15. The first side plate 135 abuts against the first clamping plate 131, and the second side plate 136 abuts against the second clamping plate 132. The first side plate 135 and the second side plate 136 are disposed opposite to each other, so that the first clamping plate 131 and the second clamping plate 132 can only approach each other and cannot move away from each other. Thus, the first clamping plate 131 and the second clamping plate 132 clamp the connecting column 12 more tightly.

[0047] The first leveling assembly 1 also includes a first hanger 151 and a second hanger 152, which are respectively disposed at the bottom of both ends of the first suspension plate 15, and the first pressure roller 17 is rotatably disposed on the first hanger 151 and the second hanger 152.

[0048] The first leveling component 1 also includes a first guide plate 153 and a second guide plate 154. The first guide plate 153 and the second guide plate 154 are disposed on the first bracket 11 and disposed at both ends of the first bracket 11. The first suspension plate 15 is provided with a first guide groove 155 and a second guide groove 156 at both ends. The first guide plate 153 is engaged in the first guide groove 155 and the second guide plate 154 is engaged in the second guide groove 156. In this way, the first suspension plate 15 cannot shake and the movement of the first suspension plate 15 in the vertical direction remains stable.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
