Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of H-beam processing technology, and more specifically, to an H-beam straightening roller with adjustable roller sleeve spacing. Background Technology

[0002] H-beams (also known as I-beams) are widely used in building steel structures, bridges, and machinery manufacturing due to their large section modulus and good bending resistance. During the production of H-beams, problems such as flange deformation, web bending, and overall twisting often occur due to rolling processes, uneven cooling, or transportation collisions. These defects need to be eliminated through straightening processes to ensure the dimensional accuracy and mechanical properties of the steel.

[0003] Existing H-beam straightening technologies employ manual screw or slider structures, requiring adjustment of roller sleeves group by group. This is cumbersome and has a limited adjustment range, making it difficult to adapt to rapid production changes (such as frequent switching between different specifications of H-beams). Although some equipment is equipped with motor-driven adjustment, the transmission structure is complex (such as gear and rack transmission), resulting in high costs and difficult maintenance, making it difficult for small and medium-sized enterprises to adopt. Existing straightening rollers lack effective guiding and limiting devices during adjustment, making it easy for the roller sleeves to shift or tilt during movement, leading to inconsistent spacing on both sides and affecting the uniformity of straightening. The sliding friction between the slider and the slideway easily generates heat and wear, increasing adjustment resistance after long-term use and even causing jamming, requiring frequent maintenance. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide an H-beam straightening roller with adjustable roller sleeve spacing, which solves the technical problems in the existing H-beam straightening technology, which uses a manual screw or slider structure, requires adjusting the roller sleeves one by one, is cumbersome to operate and has a limited adjustment range, and is difficult to adapt to rapid change-of-type production (such as frequent switching between different specifications of H-beams). Although some equipment is equipped with motor-driven adjustment, the transmission structure is complex (such as gear and rack transmission), which is costly and difficult to maintain.

[0005] According to one aspect, at least one embodiment of this disclosure provides an H-beam straightening roll with adjustable roller sleeve spacing, comprising:

[0006] A processing table, wherein a mounting frame is provided on the upper surface of the processing table;

[0007] A clamping and adjusting assembly is disposed within the mounting frame;

[0009] The clamping and adjusting assembly includes a limiting slide rail, which is located inside the mounting frame. A force-bearing block and an adjusting block are disposed inside the limiting slide rail. Both the force-bearing block and the adjusting block are provided with a rotation shaft. A mounting wheel sleeve is disposed on the rotation shaft, and the mounting wheel sleeve is provided with an insert groove. A driving bolt is disposed on the force-bearing block, with its upper end extending out of the mounting frame. A driving screw is disposed at the lower end of the adjusting block, with its lower end extending out of the lower end of the processing table.

[0010] As a further technical solution, the upper end face of the driving bolt is provided with a bolt cap, and the lower end face of the driving screw is provided with a driving hole, which is opened on the side wall of the driving bolt.

[0011] As a further technical solution, the rotary linkage assembly includes a mounting sleeve, which is disposed on the force-bearing block and the adjusting block. The mounting sleeve has a mounting cavity inside, and a mounting block is disposed inside the mounting sleeve. The upper end of the mounting block is fixedly connected to the driving bolt and the driving screw, respectively.

[0012] As a further technical solution, the mounting sleeve is provided with a snap-on cover, the side wall of the mounting sleeve is provided with an insert groove, the inside of the insert groove is provided with an insert plate, and the insert plate is fitted onto the mounting block.

[0013] As a further technical solution, the fastening cover has a through hole, and the driving bolt and the driving screw are inserted into the through hole.

[0014] As a further technical solution, the fastening cover and the mounting sleeve have connecting screw holes, and the fastening cover and the mounting sleeve are positioned corresponding to and connected to each other.

[0015] As a further technical solution, both the force-bearing block and the adjustment block are provided with a mounting platform on their sidewalls. The mounting platform is provided with a limiting piece on its sidewall. The limiting piece has a wheel groove, and a movable wheel is provided inside the wheel groove. The movable wheel is in contact with the inner sidewall of the limiting slide.

[0016] As a further technical solution, the number of mounting frames is several, and multiple mounting frames are located on opposite side walls of the processing table.

[0018] As a further technical solution, a fixing frame is provided on the inner bottom surface of the limiting slide, and a fixing sleeve is provided on the fixing frame, which meshes with the driving screw.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. In this disclosure, the precise synchronous or asynchronous adjustment of the gap between the two roller sleeves is achieved by independently adjusting the driving bolt (control force block) and the driving screw (control adjustment block), so as to adapt to the differentiated straightening requirements of the flange and web of H-beam.

[0021] 2. In this disclosure, the combination of a mounting platform, a limiting plate, and a moving wheel is used to convert sliding friction into rolling friction, thereby reducing adjustment resistance. At the same time, the linearity and stability of the roller sleeve movement are ensured by the limiting slide and the embedded structure. Attached Figure Description

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-4 As shown, it illustrates an H-beam straightening roll with adjustable roller sleeve spacing according to this disclosure, comprising:

[0035] A processing table 1 is provided with a mounting frame 2 on its upper surface;

[0036] Clamping and adjusting component 3 is installed inside the mounting frame 2;

[0037] Rotation linkage component 4 is mounted on the mounting frame 2;

[0038] The clamping and adjusting assembly 3 includes a limiting slide 3-1, which is located inside the mounting frame 2. Inside the limiting slide 3-1, there is a force-bearing block 3-2 and an adjusting block 3-3. Both the force-bearing block 3-2 and the adjusting block 3-3 are equipped with a rotation shaft 3-4. The rotation shaft 3-4 is equipped with a mounting wheel sleeve 3-5, which is equipped with an insert groove 3-6. The force-bearing block 3-2 is equipped with a driving bolt 3-7, the upper end of which extends out of the mounting frame 2. The lower end of the adjusting block 3-3 is equipped with a driving screw 3-8, the lower end of which extends out of the lower end of the processing table 1.

[0039] The rotating linkage assembly 4 includes a mounting sleeve 4-1, which is mounted on the force-bearing block 3-2 and the adjusting block 3-3. The mounting sleeve 4-1 has a mounting cavity 4-2 inside, and a mounting block 4-3 is mounted inside the mounting sleeve 4-1. The upper end of the mounting block 4-3 is fixedly connected to the driving bolt 3-7 and the driving screw 3-8 respectively.

[0040] In some examples, the force-bearing block 3-2 in the clamping adjustment assembly 3 is provided with a drive bolt 3-7. The upper end of the drive bolt 3-7 extends out of the mounting bracket 2 and has a bolt cap 3-9. When the operator rotates the bolt cap 3-9, the drive bolt 3-7 will rotate accordingly. Due to the connection between the drive bolt 3-7 and the force-bearing block 3-2, the rotation of the drive bolt 3-7 will be converted into linear movement of the force-bearing block 3-2 in the limiting slide 3-1. This is because the limiting slide 3-1 restricts the movement direction of the force-bearing block 3-2, so that it can only move along the slide.

[0041] The mounting sleeve 4-1 of the rotary linkage assembly 4 is set on the force-bearing block 3-2 and the adjusting block 3-3. The mounting cavity 4-2 inside the mounting sleeve 4-1 contains the mounting block 4-3. The upper end of the mounting block 4-3 is fixedly connected to the drive bolt 3-7 and the drive screw 3-8 respectively. When the drive bolt 3-7 or the drive screw 3-8 rotates, the mounting block 4-3 will rotate in the mounting cavity 4-2 accordingly. In this way, the rotary linkage assembly 4 can ensure the stability and reliability of the drive bolt 3-7 and the drive screw 3-8 during the rotation process, making the adjustment of the roller sleeve gap more precise and smooth.

[0042] like Figures 1-4 As shown, in this embodiment, the upper end face of the driving bolt 3-7 is provided with a bolt cap 3-9, and the lower end face of the driving screw 3-8 is provided with a through hole 5, which is opened on the side wall of the driving bolt 3-7.

[0043] In some examples, by rotating the bolt cap 3-9 in different directions (clockwise or counterclockwise), the force-bearing block 3-2 can be controlled to move forward or backward within the limiting slide 3-1, thereby changing the position of the wheel sleeve 3-5 mounted on the force-bearing block 3-2.

[0044] For example, such as Figure 4 As shown, the mounting sleeve 4-1 is provided with a snap-fit ​​cover 4-4, the side wall of the mounting sleeve 4-1 is provided with an insert groove 4-5, the inside of the insert groove 4-5 is provided with an insert plate 4-6, and the insert plate 4-6 is fitted onto the mounting block 4-3.

[0045] In some examples, the mounting plate 4-6 inside the mounting groove 4-5 on the side wall of the mounting sleeve 4-1 is fitted onto the mounting block 4-3. The mounting plate 4-6 can support and stabilize the rotation of the mounting block 4-3, reducing shaking and offset during rotation.

[0046] For example, such as Figure 4 As shown, the snap-on cover 4-4 has a drive hole 3-10, and the drive bolt 3-7 and the drive screw 3-8 are inserted into the drive hole 3-10.

[0047] In some examples, the drive hole 3-10 on the snap-on cover 4-4 provides space for the drive bolt 3-7 and the drive screw 3-8 to rotate.

[0048] For example, such as Figure 4 As shown, the fastening cover 4-4 and the mounting sleeve 4-1 have connecting screw holes 6, and the fastening cover 4-4 and the mounting sleeve 4-1 are in corresponding positions and connected.

[0049] In some examples, the snap-on cover 4-4 and the mounting sleeve 4-1 are fixed by the connecting screw hole 6, which ensures the structural stability of the entire rotating linkage assembly 4.

[0050] For example, such as Figure 3 As shown, both the force-bearing block 3-2 and the adjustment block 3-3 are provided with a mounting platform 7 on their side walls. The mounting platform 7 is provided with a limiting piece 8 on its side wall. The limiting piece 8 has a wheel groove 9, and a movable wheel 10 is provided inside the wheel groove 9. The movable wheel 10 is attached to the inner side wall of the limiting slide 3-1.

[0051] In some examples, the mounting platform 7 is located on the side wall of the force block 3-2 and the adjusting block 3-3. Its core function is to provide a mounting carrier for the limiting plate 8 and the moving wheel 10, thereby guiding and limiting the movement of the force block 3-2 and the adjusting block 3-3, and ensuring the stability and accuracy of the straightening roller spacing adjustment.

[0052] For example, such as Figure 2As shown, there are several mounting frames 2, and multiple mounting frames 2 are located on opposite side walls of the processing table 1. The limiting slide 3-1 is connected to the inner side wall of the mounting frame 2 and extends out from one side of the limiting slide 3-1 from the rotating shaft 3-4. A fixing frame 11 is provided on the inner bottom surface of the limiting slide 3-1, and a fixing sleeve 12 is provided on the fixing frame 11. The fixing sleeve 12 is engaged with the drive screw 3-8.

[0053] In some examples, the operator uses a suitable tool to insert into the drive hole 3-10 and rotates the drive screw 3-8. Since the fixing sleeve 12 on the bottom fixing bracket 11 of the limiting slide 3-1 meshes with the drive screw 3-8, according to the screw transmission principle, the rotation of the drive screw 3-8 will cause the adjusting block 3-3 to move linearly within the limiting slide 3-1.

[0054] In use, use a tool to rotate the bolt cap 3-9 on the drive bolt 3-7. When rotating the bolt cap 3-9 clockwise, the drive bolt 3-7 rotates. Since the drive bolt 3-7 is connected to the force-bearing block 3-2, the force-bearing block 3-2 will move upward within the limiting slide 3-1. When rotating the bolt cap 3-9 counterclockwise, the force-bearing block 3-2 moves downward. By observation and measurement, adjust the mounting sleeve 3-5 on the force-bearing block 3-2 to a suitable height. Use a tool to insert into the drive hole 3-10 at the lower end of the drive screw 3-8 and rotate the drive screw 3-8. Since the drive screw 3-8 meshes with the fixing sleeve 12 on the fixing bracket 11, when the drive screw 3-8 is rotated clockwise, the adjusting block 3-3 will move downward within the limiting slide 3-1; when rotated counterclockwise, the adjusting block... Move 3-3 upwards and fine-tune the drive bolt 3-7 and drive screw 3-8 to ensure the accuracy of the roller sleeve spacing. Precise measurement can be performed using measuring tools to ensure that the roller sleeve spacing on both sides is uniform. Place the H-beam to be straightened stably on the processing table 1, positioning it between the two mounting sleeves 3-5, and aligning the web and flanges of the H-beam with the insert grooves 3-6 on the mounting sleeves 3-5. Turn on the relevant equipment to start moving the H-beam. During the movement of the H-beam, the mounting sleeves 3-5 will rotate freely on the rotation axis 3-4 as the H-beam moves. The mounting sleeves 3-5 contact the H-beam through the insert grooves 3-6 and apply a certain pressure and friction to the H-beam. Under the action of this force, the bending and deformation of the H-beam are gradually corrected.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
