Description

Technical Field

[0001] This utility model relates to the field of straightening machine technology, and in particular to a straightening machine suitable for straightening soft steel profiles. Background Technology

[0002] A straightening machine suitable for straightening soft steel is a straightening device specifically designed for this particular material. Because soft steel is softer than ordinary steel, ordinary straightening machines cannot meet its straightening requirements. A straightening machine suitable for straightening soft steel, through structural design and process parameter settings, can better adapt to the characteristics of soft steel, accurately straighten it, and ensure that the soft steel achieves ideal straightness and shape accuracy while maintaining its original material properties, thus meeting the usage requirements of soft steel in different industrial fields.

[0003] A search revealed Chinese Patent Publication No. CN217941419U, which discloses a steel profile straightening machine, belonging to the technical field of straightening machines. The machine includes a straightening machine body, a control console fixedly mounted on the machine body, and a fixing plate fixedly mounted on the control console. A first hydraulic cylinder is mounted on the inner side of the fixing plate, and one end of the first hydraulic cylinder is connected to a first clamping plate. This invention utilizes the cooperation between the fixing plate and the clamping plate. Manual operation of the control console activates the first hydraulic cylinder, which in turn clamps and fixes the steel profile between the first clamping plate and the fixing plate. Then, insert the other end of the steel profile into the clamping seat, and manually rotate the adjusting disc on the threaded rod. The rotation of the threaded rod causes the second clamping plate to clamp and fix the steel profile. By operating the control panel, the torsional hydraulic motor and the second hydraulic cylinder are used in conjunction to facilitate the straightening of the steel profile. Since the straightening groove is long and the groove depth is limited, the bending degree required for the straightening of hard steel profiles is small, so the groove depth can still meet the requirements. However, when dealing with softer steel profiles, the bending degree required for straightening is large, and the existing groove depth obviously cannot meet the requirements. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a straightening machine suitable for straightening soft steel profiles, aiming to improve the problem in the prior art where the existing straightening machine cannot meet the requirement of a large degree of bending when facing soft steel profiles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a straightening machine suitable for straightening soft steel profiles, comprising a worktable, an adjustment mechanism on the top of the worktable, a pressing component on the top of the adjustment mechanism for straightening soft steel profiles, a fixing component on the right side of the worktable for fixing the adjustment mechanism, a detection component on the rear side of the worktable for detecting the degree of bending of the soft steel profiles, and a support base fixedly connected to the bottom of the worktable, with a leveling component at the bottom of the support base for adjusting the device to a horizontal state;

[0006] The adjustment mechanism includes a testing platform, the bottom of which is fixedly connected to the top of the workbench. A correction groove is provided on the top of the testing platform, and a sliding groove is provided on the bottom side of the inner side of the correction groove. Slider blocks are slidably connected to the left and right sides of the inner wall of the sliding groove. The inner walls of the two sliders are threaded with the same bidirectional lead screw. The right end of the bidirectional lead screw passes through the right side of the testing platform and is fixedly connected to a rotating disk. Adjustment pads are fixedly connected to the top of the two sliders.

[0007] Through the above technical solution: when the adjustment mechanism is working, rotating the rotating disk drives the bidirectional lead screw to rotate. Since the bidirectional lead screw is threadedly connected to the slider, the rotation of the bidirectional lead screw drives the two sliders to slide in opposite directions along the length of the detection table in the slide groove. The slider drives the top adjustment pad to move, thereby changing the distance between the two adjustment pads. This process can adjust the support position and force on the steel according to the specific conditions of the soft steel, so as to meet different straightening requirements.

[0008] As a further description of the above technical solution:

[0009] The horizontal assembly includes multiple adjusting screws, the outer walls of which are threaded to the four corners of the bottom of the support base. Each adjusting screw has an adjusting block fixedly connected to its bottom end. A lower fastening nut is threaded to the bottom of the outer wall of each adjusting screw, and an upper fastening nut is threaded to the top of the outer wall of each adjusting screw. A washer is fixedly connected to the bottom of the upper fastening nut and the top of the lower fastening nut, with one side of each washer respectively fitting against the upper and lower sides of the bottom of the support base.

[0010] The above technical solution involves rotating the adjusting block to drive the adjusting screw to rotate. Since the adjusting screw is threadedly connected to the bottom corner of the support base, the rotation causes it to move up and down on the support base, adjusting the height of the support base. When the straightening machine is on uneven ground, adjusting the adjusting screws at the four corners can make the support base level. After adjustment, tighten the upper and lower fastening nuts and use shims to increase the contact area to prevent the adjusting screw from loosening, ensuring the straightening machine is placed stably and the straightening work is carried out smoothly.

[0011] As a further description of the above technical solution:

[0012] The fixing component includes an L-shaped plate, the left side of which is fixedly connected to the right side of the testing table. A slot is provided on the front side of the L-shaped plate, and a tightening groove is provided at the bottom of the inner wall of the slot. A screw is threadedly connected to the front side of the L-shaped plate.

[0013] The above technical solution involves tightening the screw on the front side of the L-shaped plate. The screw is screwed into the tightening groove, generating a compressive force. This pressure causes the component to fit tightly against the slot, thus securing the bidirectional lead screw and preventing it from rotating during the straightening process, thereby ensuring straightening accuracy.

[0014] As a further description of the above technical solution:

[0015] The detection assembly includes two fixed plates. The bottom of each fixed plate is fixedly connected to the top rear side of the workbench. The same automatic rotary shaft is rotatably connected to adjacent sides of the two fixed plates. A connecting block is fixedly connected to the front side of the automatic rotary shaft. A vertical adjusting rod is slidably connected to the inner wall of the connecting block. A screw is threadedly connected to the front side of the connecting block. The rear end of the screw is in contact with the front side of the vertical adjusting rod. A horizontal sliding rod is fixedly connected to the top of the vertical adjusting rod. A detection head is slidably connected to the outer wall of the horizontal sliding rod. A screw is threadedly connected to the bottom right side of the detection head.

[0016] The above technical solution allows for the automatic rotation of the detection head after straightening, and the vertical adjustment rod to slide on the inner wall of the connecting block. By tightening and loosening screw two, the vertical position can be fixed and the height of the detection head can be adjusted. The detection head can slide on the horizontal slide bar, and the horizontal position can be fixed by tightening screw three, thereby accurately positioning the detection head and achieving accurate detection of the bending degree of soft steel.

[0017] As a further description of the above technical solution:

[0018] The pressing assembly includes a fixed base, the front side of which is fixedly connected to the rear side of the worktable, a pressing seat fixedly connected to the top of the fixed base, a hydraulic rod fixedly connected to the bottom of the pressing seat, and a pressing head fixedly connected to the bottom end of the hydraulic rod.

[0019] Through the above technical solution: the hydraulic rod works under the command of the control system. When the hydraulic rod extends under the support of the lower pressure seat at the top of the fixed seat, it drives the lower pressure head to descend and apply pressure to the soft steel section placed on the testing table. The pressure causes the steel section to deform, thereby straightening the soft steel section.

[0020] As a further description of the above technical solution:

[0021] Both of the adjusting pads have an arc-shaped groove 2 at their top, and the inner wall of the correction groove has an arc-shaped groove 1 at its top on both the left and right sides. The inner walls of the two arc-shaped grooves 1 and 2 are both arc-shaped, and the inner walls of the two arc-shaped grooves 1 and 2 are in contact with the soft steel profile during the pressing process.

[0022] The above technical solution involves placing the steel profile in the straightening groove and pressing down with the pressure head. At this time, the first arc groove fits against the steel profile from both sides and the second arc groove from the bottom. The inner walls of the first and second arc grooves are arc-shaped, which increases the contact area with the steel profile, makes the pressure evenly distributed, avoids excessive local pressure and uneven deformation of the steel profile, and achieves stable and accurate straightening.

[0023] As a further description of the above technical solution:

[0024] A limiting block is fixedly connected to the front end of the transverse slide bar, and a buffer pad is fixedly connected to the rear side of the limiting block. The rear side of the buffer pad is in contact with the front side of the detection head.

[0025] The above technical solution involves the detection head sliding along the horizontal slide bar. When it approaches the front end, it contacts the buffer pad. The limiting block restricts the excessive sliding of the detection head through the buffer pad, avoiding collision damage and ensuring stable and accurate detection.

[0026] As a further description of the above technical solution:

[0027] Each of the lower fastening nuts has a tapered foot rotatably connected to its bottom, and each of the tapered feet has a rubber pad fixedly connected to its bottom.

[0028] The above technical solution allows for the adjustment of the height of the conical feet by rotating the lower fastening nut. The contact between the conical feet and the ground increases stability, while the bottom rubber pad increases friction with the ground to prevent the equipment from sliding and ensure stable operation of the straightening machine.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, when straightening soft steel profiles, the rotating disc is rotated to adjust the spacing of the adjusting pads to adapt to the hardness of the steel profile. The steel profile is placed in the straightening groove, and the detection head is pressed into the groove to measure the curvature. The pressing component presses down, and the adjusting pads cooperate to increase the deformation at the bending point to meet the straightening requirements. The fixing component prevents displacement and can also adjust the position of the detection head to adapt to the width of the steel profile. After straightening, the rotating shaft automatically resets the detection head. This straightening machine solves the problem of insufficient groove depth in existing straightening machines and improves the straightening efficiency and quality of soft steel profiles.

[0031] 2. In this utility model, rotating the adjusting block drives the adjusting screw to rotate. Because the adjusting screw is threadedly connected to the bottom corner of the support base, it moves up and down at the bottom of the support base during rotation, adjusting the height of the support base. Adjusting the adjusting screws at each corner separately ensures that the support base is horizontal, ensuring that the straightening machine is placed stably. After adjustment, tighten the upper and lower fastening nuts to make the shims fit tightly against the bottom of the support base, reinforcing the adjusting screws and preventing them from loosening due to vibration, maintaining a horizontal state, improving straightening accuracy, and extending the equipment life.

[0040] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a straightening machine suitable for straightening soft steel profiles, including a worktable 1. The worktable 1 provides an installation and working platform. An adjustment mechanism 2 is provided on the top of the worktable 1. The adjustment mechanism 2 is used to make targeted adjustments to the straightening process according to the characteristics of the soft steel profile. A pressing component 6 is provided on the top of the adjustment mechanism 2. The pressing component 6 is specifically used to apply pressure to the soft steel profile to correct its shape and make it meet the straightness requirements. A fixing component 4 is provided on the right side of the worktable 1. The fixing component 4 is used to firmly fix the adjustment mechanism 2 to prevent displacement of the adjustment mechanism 2 during the straightening process. A detection component 5 is provided on the rear side of the worktable 1. The detection component 5 is used to accurately detect the degree of bending of the soft steel profile, which is used for subsequent straightening. The straightening machine provides data support for the operation. A support base 7 is fixedly connected to the bottom of the workbench 1, providing stable support for the entire machine and ensuring its stability during operation. A leveling component 3 is installed at the bottom of the support base 7, allowing adjustment of the entire device to maintain a horizontal position and prevent tilting from affecting straightening accuracy. The adjustment mechanism 2 includes a detection table 201, whose bottom is fixedly connected to the top of the workbench 1, serving as a load-bearing and positioning element, providing a specific working area for the detection and straightening of soft steel profiles. A straightening groove 202 is provided on the top of the detection table 201, used to place the soft steel profile to be straightened, providing space for straightening. A sliding groove 203 is provided on the inner bottom side of the straightening groove 202. The groove 203 provides a sliding track for the slider 204, allowing the slider 204 to move smoothly within it. Slider 204s are slidably connected to both the left and right sides of the inner wall of the groove 203, allowing the slider 204 to slide along the groove 203 to adjust its position. The inner walls of both sliders 204 are threaded with the same bidirectional lead screw 205. The bidirectional lead screw 205 drives the two sliders 204 to move synchronously through rotation, achieving precise adjustment of the position of the adjusting pad 207. The right end of the bidirectional lead screw 205 passes through the right side of the testing table 201 and is fixedly connected to a rotating disk 206. The rotating disk 206 allows the operator to manually rotate the bidirectional lead screw 205, thereby controlling the movement of the sliders 204. Adjusting pads 207 are fixedly connected to the tops of both sliders 204 for adjustment. The pad 207 can adjust its contact position and support force with the steel section according to the actual situation of the steel section. The bottom of both adjusting pads 207 are slidably connected to the bottom inner wall of the straightening groove 202 to ensure the stability and smoothness of the adjusting pads 207 during the adjustment process. The fixing component 4 includes an L-shaped plate 401. The left side of the L-shaped plate 401 is fixedly connected to the right side of the testing table 201 for connection with the testing table 201, providing a foundation for subsequent fixing operations. The front side of the L-shaped plate 401 has a slot 402 for accommodating and positioning related components for fastening operations. The bottom inner wall of the slot 402 has a tightening compression groove 403. When tightening the screw 404, the tightening compression groove 403 can increase the compressive force on the related components.To enhance the stability of the fixation, screws 404 are threaded onto the front side of the L-shaped plate 401. By tightening screws 404, the components to be fixed are firmly secured to the L-shaped plate 401. The detection assembly 5 includes two fixing plates 501, the bottoms of which are fixedly connected to the top rear side of the worktable 1 to fix and support the automatic rotary shaft 502, ensuring its stability during operation. The same automatic rotary shaft 502 is rotatably connected to adjacent sides of the two fixing plates 501. The automatic rotary shaft 502 can rotate automatically, driving the connecting block 503 to rotate, thereby adjusting the angle of the detection head 507. A connecting block 503 is fixedly connected to the front side of the 2-axis shaft. The connecting block 503 is used to connect the automatic rotary shaft 502 and the vertical adjusting rod 505 to transmit motion and power. The vertical adjusting rod 505 is slidably connected to the inner wall of the connecting block 503. The vertical adjusting rod 505 can slide up and down on the inner wall of the connecting block 503 to adjust the position of the detection head 507 in the vertical direction. A screw 504 is threadedly connected to the front side of the connecting block 503. The screw 504 is used to fix the vertical adjusting rod 505 to the connecting block 503 after it has been adjusted to the appropriate position. The rear end of the screw 504 is in contact with the front side of the vertical adjusting rod 505. It can be tightened and loosened. Screw 2 504 controls the fixing and movement of the vertical adjusting rod 505. A horizontal slide rod 506 is fixedly connected to the top of the vertical adjusting rod 505. The horizontal slide rod 506 provides a track for the horizontal sliding of the detection head 507, enabling the horizontal position adjustment of the detection head 507. The detection head 507 is slidably connected to the outer wall of the horizontal slide rod 506, and slides along the horizontal slide rod 506 to adapt to different detection requirements. Screw 3 508 is threadedly connected to the bottom right side of the detection head 507. Screw 3 508 is used to fix the detection head 507 to the horizontal slide rod 506 after it has been adjusted to the appropriate position. (The last sentence appears to be a separate, unrelated section: "Pressing component 6 packages...") The system includes a fixed base 601, whose front side is fixedly connected to the rear side of the workbench 1, used to fix the pressure seat 602 and provide stable support for the pressing operation. The pressure seat 602 is fixedly connected to the top of the fixed base 601, and the pressure seat 602 is used to install and fix the hydraulic rod 603 to ensure the stability of the hydraulic rod 603 during operation. The hydraulic rod 603 is fixedly connected to the bottom of the pressure seat 602. The hydraulic rod 603 provides downward pressure to the pressure head 604 through its telescopic movement. The pressure head 604 is fixedly connected to the bottom end of the hydraulic rod 603. The pressure head 604 acts directly on the soft steel profile, straightening the steel profile by applying pressure.

[0041] Specifically, the distance between the two adjusting pads 207 is adjusted according to the hardness of the steel profile. Rotating the rotating disk 206 drives the double-acting screw 205 to rotate. The double-acting screw 205 drives two sliders 204 to slide in opposite directions within the groove 203, thereby adjusting the distance between the two adjusting pads 207 to accommodate steel profiles of different hardness. Furthermore, the top surfaces of the two adjusting pads 207 are not higher than the top surface of the testing table 201, and they are symmetrically distributed on both sides of the testing head 507 along the length of the testing table 201. The bending degree of the soft steel profile is detected using the testing component 5. The soft steel profile is then placed... On the straightening groove 202 of the testing table 201, due to the weight of the steel profile, the testing head 507 is pressed and slowly rotates into the straightening groove 202. During this process, the testing head 507 begins to detect the curvature of the steel profile. Two adjusting pads 207 are symmetrically distributed on both sides of the testing head 507 along the length of the testing table 201, with a small spacing. This layout can more accurately detect the curvature of the steel profile. After the test is completed, the pressing component 6 begins to function. The hydraulic rod 603 at the bottom of the pressing seat 602 extends, driving the pressing head 604 to press down on the steel profile. Due to the spacing between the adjusting pads 207... When the lower pressure head 604 presses down, it indirectly increases the deformation at the bend of the steel section, meeting the requirement for a larger bending degree for straightening soft steel sections. During this process, the L-shaped plate 401 in the fixing assembly 4 locks the detection table 201 through the slot 402, and the adjusting mechanism 2 is firmly fixed on the worktable 1 by tightening the screw 404 to prevent displacement during the straightening process and affecting the straightening effect. The position of the detection head 507 on the transverse slide bar 506 can be adjusted by loosening the screw 508 to accommodate steel sections of different widths. Tighten screw 3 508 to complete the fixing. After the straightening of the curved steel section is completed, the automatic rotary shaft 502 starts to rotate automatically. The front side of the automatic rotary shaft 502 is connected to the connecting block 503, and the detection head 507 is connected to the connecting block 503 through the vertical adjusting rod 505 and the horizontal sliding rod 506. As the automatic rotary shaft 502 rotates, the squeezed detection head 507 is returned to its original position, preparing for the next inspection and straightening work. This straightening machine successfully solves the problem that the groove depth in the existing technology cannot meet the straightening requirements of soft steel sections, and improves the efficiency and quality of soft steel section straightening.

[0042] Reference Figure 1 , Figure 2 and Figure 5The horizontal component 3 includes multiple adjusting screws 301. The adjusting screws 301 are used to change their position at the bottom of the support base 7 by rotation, thereby adjusting the height of the straightening machine. The outer walls of the multiple adjusting screws 301 are threadedly connected to the four corners of the bottom of the support base 7, enabling independent adjustment of the height of the four corners of the support base 7 to adapt to ground with different flatness. Each adjusting screw 301 has an adjusting rotating block 303 fixedly connected to its bottom end. The adjusting rotating block 303 allows the operator to manually rotate the adjusting screw 301, making the adjustment process more convenient. Each adjusting screw 301 has a lower fastening nut 302 threadedly connected to its bottom outer wall. The lower fastening nut 302 is used to tighten the screw after adjustment. Afterwards, tightening prevents the adjusting screw 301 from loosening downwards. The top of the outer wall of each of the multiple adjusting screws 301 is threaded with an upper fastening nut 304. The upper fastening nut 304 is also tightened after adjustment to prevent the adjusting screw 301 from loosening upwards. The bottom of the multiple upper fastening nuts 304 and the top of the multiple lower fastening nuts 302 are fixedly connected with washers 305. The washers 305 increase the contact area with the bottom of the support base 7, making the fastening force distribution more even. One side of each washer 305 is in contact with the upper and lower sides of the bottom of the support base 7, respectively, to ensure that the upper fastening nuts 304 and the lower fastening nuts 302 can stably fix the relative position of the adjusting screw 301 and the support base 7.

[0043] Specifically, when adjusting the level of the straightening machine, the adjusting screw 301 can be rotated by rotating the adjusting block 303. Since the adjusting screw 301 is threadedly connected to the four corners of the bottom of the support base 7, it moves up and down at the bottom of the support base 7 as the adjusting screw 301 rotates, thereby adjusting the height of the support base 7. By adjusting the adjusting screws 301 at the four corners respectively, the support base 7 can be kept in a horizontal state, ensuring that the straightening machine is placed stably. The lower fastening nut 302 and the upper fastening nut 304 are located at the bottom and top of the outer wall of the adjusting screw 301, respectively. After adjustment, tighten the lower fastening nut 302 and the upper fastening nut 304. The shim 305 fits tightly against the bottom upper and lower sides of the support base 7 to reinforce it and prevent the adjusting screw 301 from loosening due to equipment vibration. This ensures that the straightening machine maintains a stable horizontal state during operation, thereby improving the straightening accuracy of soft steel and extending the service life of the equipment.

[0044] Reference Figure 1 , Figure 3 and Figure 4Both adjusting pads 207 have arc-shaped grooves 13 on their tops, which better fit the bottom of the soft steel profile. The top of the left and right sides of the inner wall of the straightening groove 202 has arc-shaped grooves 12, which can contact the soft steel profile during downward pressure from the side. The inner walls of both arc-shaped grooves 12 and 13 are arc-shaped, which increases the contact area with the soft steel profile, making the straightening pressure more uniform. The inner walls of both arc-shaped grooves 12 and 13 fit snugly against the soft steel profile during downward pressure, ensuring stable support and precise straightening of the steel profile during the straightening process. (The text also mentions a transverse sliding rod.) A limiting block 8 is fixedly connected to the front end of 506. The limiting block 8 is used to limit the excessive forward sliding of the detection head 507. A buffer pad 9 is fixedly connected to the rear side of the limiting block 8. The buffer pad 9 can buffer when the detection head 507 touches the limiting block 8. The rear side of the buffer pad 9 fits against the front side of the detection head 507 to prevent the detection head 507 from being damaged by collision. The bottom of multiple lower fastening nuts 302 is rotatably connected to a tapered foot 10. The tapered foot 10 is easy to insert into uneven ground and enhances the stability of the equipment. The bottom of multiple tapered feet 10 is fixedly connected to a rubber pad 11. The rubber pad 11 increases the friction with the ground and further stabilizes the straightening machine.

[0045] Specifically, the arc-shaped grooves 13 on the top of the two adjusting pads 207 and the arc-shaped grooves 12 on the top of the left and right sides of the inner wall of the straightening groove 202 have arc-shaped inner walls that fit against the soft steel profile during the pressing process. This design increases the contact area with the soft steel profile, making the pressure evenly distributed and avoiding uneven deformation of the steel profile due to excessive local pressure, thereby improving the straightening effect. The limiting block 8 at the front end of the transverse slide bar 506 and the buffer pad 9 at the rear end restrict excessive sliding of the detection head 507 when it is adjusted. The buffer pad 9 buffers the detection head 507 when it touches the limiting block 8, preventing damage to the detection head 507 due to collision and ensuring the accuracy and stability of the adjustment of the detection head 507. The tapered feet 10 and the rubber pads 11 at the bottom of the multiple lower fastening nuts 302 are rotatably connected. The tapered feet 10 and the rubber pads 11 increase the friction with the ground, making the straightening machine more stable and preventing the straightening quality from being affected by the shaking of the equipment during the straightening process.

[0046] Working principle: When it is necessary to straighten soft steel profiles, the distance between the two adjusting pads 207 is adjusted according to the hardness of the steel profile. Rotating the rotating disk 206 drives the double-acting screw 205 to rotate. The double-acting screw 205 drives the two sliders 204 to slide in opposite directions within the groove 203, thereby adjusting the distance between the two adjusting pads 207 to accommodate steel profiles of different hardness. Furthermore, the top surfaces of the two adjusting pads 207 are not higher than the top surface of the testing table 201, and they are symmetrically distributed on both sides of the testing head 507 along the length of the testing table 201. The degree of bending of the soft steel profile is detected by the testing component 5. The soft steel profile is placed on the straightening groove 202 of the testing table 201. Due to the weight of the steel profile, the testing head 507 is pressed and slowly rotates into the straightening groove 202. During this process, the testing head 507 begins to detect the curvature of the steel profile. Two adjusting pads 207 are symmetrically distributed on both sides of the testing head 507 along the length of the testing table 201, with a small spacing. This layout can more accurately detect the curvature of the steel profile. After the test is completed, the pressing component 6 begins to function. The hydraulic rod 603 at the bottom of the pressing seat 602 extends, driving the pressing head 604 to press down on the steel profile. Due to the weight of the adjusting pads 207, the steel profile is pressed down by the straightening groove 202. The small spacing between 07 and 08 allows the downward pressure head 604 to indirectly increase the deformation at the bend of the steel section, thus meeting the requirement for greater bending degree in the straightening of soft steel sections. During this process, the L-shaped plate 401 in the fixing assembly 4 secures the detection table 201 through the slot 402, and the adjusting mechanism 2 is firmly fixed on the worktable 1 by tightening screw 404 to prevent displacement during the straightening process and affecting the straightening effect. By loosening screw 508, the position of the sliding detection head 507 on the transverse slide bar 506 can be adjusted to accommodate steel sections of different widths. After tightening screw 3 508, the straightening of the curved steel section is completed. After the straightening of the curved steel section is completed, the automatic rotating shaft 502 starts to rotate automatically. The front side of the automatic rotating shaft 502 is connected to the connecting block 503, and the detection head 507 is connected to the connecting block 503 through the vertical adjusting rod 505 and the horizontal sliding rod 506. As the automatic rotating shaft 502 rotates, the squeezed detection head 507 is returned to its original position, preparing for the next inspection and straightening work. This straightening machine successfully solves the problem that the groove depth in the existing technology cannot meet the straightening requirements of soft steel sections, and improves the efficiency and quality of soft steel section straightening.

[0047] Furthermore, when it is necessary to adjust the level of the straightening machine, the adjusting screw 301 can be rotated by rotating the adjusting block 303. Since the adjusting screw 301 is threadedly connected to the four corners of the bottom of the support base 7, it moves up and down at the bottom of the support base 7 as the adjusting screw 301 rotates, thereby adjusting the height of the support base 7. By adjusting the adjusting screws 301 at the four corners respectively, the support base 7 can be kept in a horizontal state, ensuring that the straightening machine is placed stably as a whole. The lower fastening nut 302 and the upper fastening nut 304 are located at the bottom and top of the outer wall of the adjusting screw 301, respectively. After the adjustment is completed, tighten the lower fastening nut 302 and the upper fastening nut 304. The shim 305 fits tightly against the bottom upper and lower sides of the support base 7 to reinforce it and prevent the adjusting screw 301 from loosening due to equipment vibration. This ensures that the straightening machine maintains a stable horizontal state during operation, thereby improving the straightening accuracy of soft steel and extending the service life of the equipment.
