Description

Technical Field

[0001] The utility model relates to the technical field of correction equipment, in particular to a high-toughness low-carbon alloy steel correction device. Background Art

[0002] With the rapid development of modern industrial technology, high-toughness low-carbon alloy steel, as a high-quality material, has been widely used in the engineering field due to its excellent toughness, strength and wear resistance. Especially in the manufacture of steel bars. However, in the actual production process, due to the influence of processing, transportation, storage and other links, steel bars made of high-toughness low-carbon alloy steel often have deformation phenomena such as bending and twisting. These deformations not only affect the appearance quality of the steel bars, but more importantly, reduce their performance and may even bring safety hazards to the engineering structure. Therefore, special straightening equipment is needed for correction.

[0003] Deficiencies of existing technology:

[0004] At present, the common steel bar straightening machine mainly corrects the twisted steel bars through the internal correction roller group and clamp. When working, one end of the steel bar is clamped and fixed, and then the other end of the steel bar is sent between the correction roller group. The correction effect is achieved by pressing the steel bar with the correction roller group. Although this is one of the most common steel bar correction methods at present, there are still certain defects. Since the steel bar channel between the roller groups is horizontal, the twisted steel bar can only be corrected to 180 degrees when passing between the roller groups. When the steel bar leaves the roller group, it will still rebound to a certain extent due to its own toughness, especially for steel bars made of high-toughness low-carbon alloy steel. This phenomenon will be more obvious due to its strong toughness. Therefore, in fact, the traditional straightening machine alone cannot completely straighten the steel bar, and the correction effect is poor. When the degree of distortion of the steel bar is small, due to the existence of toughness, the traditional straightening machine has almost no correction effect. Therefore, the existing straightening machine can hardly meet the current actual correction needs. Utility Model Content

[0033] See also Figure 1-4As shown, the utility model provides a technical solution for a high-toughness low-carbon alloy steel correction device: a high-toughness low-carbon alloy steel correction device, comprising a mounting platform 1, sliding components 2 are respectively provided on both sides of the upper end surface of the mounting platform 1, and clamping components 3 and correction components 4 for straightening steel bars are respectively installed on the sliding components 2. The correction component 4 includes a correction seat 401, a crank 403 and a top block 404. The correction seat 401 is installed on the sliding component 2 on one side of the mounting platform 1, and a top rod 402 is movably installed on the upper end of the correction seat 401, one end of the top rod 402 is slidably connected to the sliding hole on the correction seat 401, and the other end of the top rod 402 is connected to the threaded hole on the correction seat 401 by opening a thread. The crank 403 is installed at the end of the top rod 402 away from the clamping component 3. The top block 404 is rotatably connected to one end of the top rod 402 adjacent to the clamping assembly 3. The end of the top block 404 is provided with a multi-layer positioning groove 405 for positioning the steel bars. The diameter of each layer of the multi-layer positioning groove 405 gradually increases from the inside to the outside to match steel bars of different diameters. When it is necessary to correct the twisted steel bars, first fix the twisted steel bars on the clamping assembly 3 on the mounting platform 1 so that the protruding part of the steel bar to be processed faces the top block 404. Then, the position of the correction seat 401 is adjusted by the sliding assembly 2 so that the top block 404 is aligned with the protruding part of the steel bar to be corrected. Then, the top rod 402 is rotated by the crank 403. The top rod 402 drives the top block 404 along the sliding hole on the correction seat 401 to push the twisted part of the steel bar to move in the opposite direction. When the twisted part of the steel bar is completely straightened, the crank is reversed. Separate the top block 404 from the steel bar by 403, and observe the steel bar correction and recovery state. If the steel bar is still in a slightly twisted state due to its own high toughness, continue to turn the crank 403 to drive the top rod 402 and the top block 404 forward until the part of the steel bar to be corrected shows a slight reverse bend. The specific reverse bending angle can be determined according to the toughness of the steel bar itself. The greater the toughness of the steel bar, the greater the required correction angle. Finally, separate the top block 404 from the steel bar to observe the steel bar correction and recovery state. If it is still not recovered, continue to repeat the above operation or adjust the correction angle. Through the correction component 4, the effect of reverse bending correction of the twisted part of the high-toughness steel bar to be corrected is achieved, and the toughness of the steel bar is counteracted. Compared with the traditional straightening machine, the negative impact of the steel bar toughness on the correction and recovery is solved, and it is ensured that the slightly twisted steel bar can also be effectively corrected, which improves the practicality of the correction device.

[0034] The sliding assembly 2 includes a first slide groove 201, a positioning hole 203 and a positioning pin 205.

When the horizontal position of the clamping assembly 3 and the correction assembly 4 needs to be adjusted, first overcome the attraction of the permanent magnet 206 and pull out the positioning pin 205, so that the correction seat 401 and the clamping assembly 3 are in an unlimited position state, and then the correction seat 401 and the clamping assembly 3 are horizontally moved to the specified position respectively, and the positioning holes 203 on the correction seat 401 and the clamping assembly 3 are aligned with the corresponding through holes 204 below, and the positioning pin 205 is inserted into the positioning hole 203 through the through hole 204 again. At this time, the horizontal position adjustment of the clamping assembly 3 and the correction seat 401 is completed. Through the sliding assembly 2, the position of the correction seat 401 and the clamping assembly 3 in the first slide groove 201 and the second slide groove 202 is flexibly adjusted, which is more conducive to the fixation and correction of steel bars of different lengths and different twisted parts, and improves the convenience of operation.

[0035] The clamping assembly 3 includes two clamping seats 301 and a clamping cover 302. The two clamping seats 301 are slidably connected in the groove of the second slide groove 202, and the positioning holes 203 are opened at the lower ends of the two clamping seats 301. The clamping cover 302 is movably installed on the upper ends of the two clamping seats 301, and the clamping cover 302 and the two ends of the two clamping seats 301 are connected with fixing bolts 303. When it is necessary to clamp the steel bar, first loosen the fixing bolt 303, then place the steel bar on the two clamping seats 301 on both sides, and the part of the steel bar to be corrected is located between the two clamping seats 301, then cover the clamping cover 302, and tighten the fixing bolt 303.

[0038] Tooth grooves 7 for increasing friction are provided in the clamping grooves of the clamping cover 302 and the two clamping seats 301. The tooth grooves 7 can improve the reliability of steel bar clamping and reduce the possibility of steel bar rotation during the correction process.

[0039] The working principle of the utility model is as follows:

[0040] When using the high-toughness low-carbon alloy steel correction device of this embodiment, if the twisted steel bar needs to be corrected, first loosen the fixing bolt 303, then place the steel bar on the two clamping seats 301 on both sides, the part of the steel bar to be corrected is located between the two clamping seats 301, and the protruding part to be processed is facing the top block 404, then cover the clamping cover 302, and tighten the fixing bolt 303 to complete the clamping and fixing of the steel bar. Then overcome the attraction of the permanent magnet 206 and pull out the positioning pin 205, so that the correction seat 401 is in an unlimited position state, then move the correction seat 401 horizontally so that the top block 404 is aligned with the protruding part of the steel bar to be corrected, and the positioning hole 203 below the correction seat 401 is aligned with the corresponding through hole 204 below, and the positioning pin 205 is inserted into the positioning hole 203 through the through hole 204 again. At this time, the horizontal position adjustment of the correction seat 401 is completed. If the horizontal position of the two clamping seats 301 needs to be adjusted, the same operation can be performed according to the above method. Then, the top rod 402 is rotated by the crank handle 403, and the top rod 402 drives the top block 404 along the sliding hole on the correction seat 401 to push the twisted part of the steel bar to move in the opposite direction. When the twisted part of the steel bar is completely straightened, the crank handle 403 is reversed to separate the top block 404 from the steel bar, and the correction recovery state of the steel bar is observed. If the steel bar is still in a slightly twisted state due to its own toughness, the crank handle 403 is continued to be rotated to drive the top rod 402 and the top block 404 to move forward until the part of the steel bar to be corrected shows a slight reverse bend. The specific reverse bending angle can be determined according to the toughness of the steel bar itself. The greater the toughness of the steel bar, the greater the required correction angle. Finally, the top block 404 is separated from the steel bar and the correction recovery state of the steel bar is observed. If it has not recovered yet, continue to repeat the above operation or adjust the correction angle.
