Description

Technical Field

[0001] This application relates to the field of angle steel production technology, and in particular to a straightening device for an angle steel production line. Background Technology

[0002] Angle steel is a long strip of steel with two sides perpendicular to each other, forming an angle. It is a commonly used steel material in large-scale machining. Angle steel is prone to twisting and deformation during use. To ensure that angle steel always remains straight, angle steel straightening machines are mostly used to restore it to its original shape. The straightening device used in angle steel production lines is a device specifically designed to "straighten" bent angle steel, restoring its straightness for easier subsequent processing and use.

[0003] Patent document CN115007687B discloses a straightening device for a mechanical angle steel production line. This invention uses two straightening bases, one with movable magnetic blocks and the other with fixed magnetic blocks, to straighten the angle steel. The angle steel to be straightened is placed between the two bases and subjected to the pressing force of a first hydraulic press on a first straightening block. The straightening bases and the first straightening block clamp the angle steel together, achieving straightening. After straightening, the first hydraulic press applies further pressure, making the pressing force of the first straightening block greater than the clamping force between the movable and fixed magnetic blocks. This causes the straightened angle steel to pass between the straightening bases and move away from them. When the first straightening block retracts, the straightening base pushes it out, pushing the angle steel away from the first straightening block, thus facilitating material removal.

[0004] Patent document CN210253674U discloses a pre-treatment straightening device for a CNC punching production line of angle steel. The device includes a worktable with a support frame on its outer side. A cylinder is threadedly fixed to the top of the support frame, and the output rod of the cylinder is fixedly connected to a triangular pressure plate. The worktable has a U-shaped structure, and a shaping bottom mold is fixedly welded to the bottom side of its center. Horizontal cylinders are fixedly welded to the top of both ends of the worktable. The end of each horizontal cylinder near the triangular pressure plate is open. Scrapers are slidably connected inside each horizontal cylinder, and load-bearing vertical plates are fixedly connected to the bottom sides of the scrapers. A through hole is formed on the bottom side of each horizontal cylinder, and the bottom end of the load-bearing vertical plate passes through the through hole and extends to the bottom side of the horizontal cylinder. This invention improves efficiency and safety, facilitates use, and meets the needs of people in production and daily life.

[0050] The implementation principle of a straightening device for an angle steel production line according to an embodiment of this application is as follows: In use, firstly, according to the specifications of the angle steel to be straightened, the first drive motor 11 is started. The first drive motor 11 drives the bidirectional lead screw 4 to rotate, and the bidirectional lead screw 4 drives two moving blocks 5 to slide relative to each other along the groove at the bottom of the protective plate 3, thereby driving multiple pressure rollers on the two sliding plates 6 to adjust to a suitable distance. Then, the angle steel to be straightened is fed in from the right side of the working chamber 2, and simultaneously the resistance wire and the second drive motor 14 are started. The resistance wire generates heat when energized, and the second drive motor 14 drives the first rotating shaft 13 to rotate. The first rotating shaft 13 drives the impeller to rotate, evenly blowing heat onto the angle steel to achieve preheating. After preheating, the angle steel continues to be conveyed forward and enters between multiple pressure rollers. The multiple pressure rollers roll under the drive of the angle steel to straighten the bent angle steel. During the straightening process, multiple buffer springs 9 elastically expand and contract according to the degree of bending of the angle steel, buffering the pressure of the pressure rollers on the angle steel and reducing vibration and surface damage. At the same time, the second drive motor 14 drives the first bevel gear 15 to rotate. The first bevel gear 15 drives the second bevel gear 16 to rotate, which in turn drives the first drive shaft 17 to rotate. The first drive shaft 17 drives the second sprocket 29 to rotate via the first sprocket 27 and the first chain 28. The second sprocket 29 drives the second drive shaft 24 to rotate. The second drive shaft 24 drives the nozzle 18 to rotate via the third bevel gear 25 and the fourth bevel gear 26. At the same time, the suction pump 21 is started. The suction pump 21 delivers the cooling water in the water tank 19 to the nozzle 18 through the first delivery pipe 22 and the second delivery pipe 23. 8. The rotating nozzle 18 sprays cooling water evenly onto the straightened angle steel to achieve rapid cooling and shaping. In addition, when the second drive shaft 24 rotates, it drives the fourth sprocket 32 ​​to rotate through the third sprocket 30 and the second chain 31. The fourth sprocket 32 ​​drives the second rotating shaft 20 to rotate, and the second rotating shaft 20 drives the stirring roller to rotate, stirring the cooling water in the water tank 19 to avoid local overheating and ensure the cooling effect. The cooled and shaped angle steel is sent out from the left side of the working chamber 2, completing the entire straightening process.

[0051] Example 2:

[0052] The difference between this embodiment and Embodiment 1 is that: guide frames are fixedly installed at both the right inlet and the left outlet of the working chamber 2. Two symmetrically arranged guide rollers are rotatably installed on the guide frames. The outer wall of the guide rollers is provided with slots that are compatible with the angle steel. The guide rollers can guide the conveying direction of the angle steel, prevent the angle steel from deviating during the conveying process, ensure that the angle steel accurately enters between the pressure rollers, and improve the straightening accuracy. The slots can make the angle steel fit better with the guide rollers, further improving the guiding stability.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
