[0067] like Figure 1 As shown, the present application provides a steel rolling auxiliary straightening device, which includes a width straightening mechanism 10 and a thickness straightening mechanism 20, wherein:

[0068] A width straightening mechanism 10, comprising a first straightening plate 11 and a second straightening plate 12 which are arranged oppositely and at intervals, the first straightening plate 11 and the second straightening plate 12 are both straight plates with smooth surfaces, and the heights of the first straightening plate 11 and the second straightening plate 12 are greater than the thickness of the steel billet 100, a driving assembly 13 is connected between the first straightening plate 11 and the second straightening plate 12, and the driving assembly 13 is configured to drive the first straightening plate 11 to move relative to the second straightening plate 12, so as to adjust the spacing between the first straightening plate 11 and the second straightening plate 12 to the width of the steel plate actually to be rolled, so as to make the width of the steel billet 100 passing through the width straightening structure consistent, and the side surface along the width direction is flat;

[0069] The thickness straightening mechanism 20 includes two vertical plates 21 disposed on both sides of the width straightening mechanism 10, that is, the two vertical plates 21 are disposed on both sides of the width straightening mechanism 10 along the traveling direction of the steel billet 100, and two groups of rolling rollers 22 are disposed between the two vertical plates 21. The two groups of rolling rollers 22 are respectively located at the upper and lower ends of the width straightening mechanism 10. The rolling rollers 22 are configured to press the steel billet 100 so that the thickness of the steel billet 100 is within a preset range. Two groups of rolling rollers 22 are installed on each vertical plate 21. The adjusting components 23 are arranged at intervals, and the steel rolling rollers 22 are connected to the adjusting components 23. The adjusting components 23 are configured to keep the distance between the two groups of steel rolling rollers 22 within a preset range, that is, the distance between the two groups of steel rolling rollers 22 is adjusted by the adjusting components 23 so that the distance between the two steel rolling rollers 22 is roughly the same as the thickness of the steel (billet) to be rolled, wherein the preset range is the target rolling thickness of the billet 100 and its allowable error, and the error range is 0.1mm to 1mm.

[0070] The steel rolling auxiliary straightening equipment of the utility model, by setting a width straightening mechanism 10, straightens the width of the steel plate and the side along the width direction to ensure that the side along the width direction of the steel plate is straight and the width is consistent. By setting a thickness straightening mechanism 20, the thickness of the steel plate is straightened within a preset range to ensure that the thickness of the steel plate is roughly uniform, thereby meeting the processing and manufacturing requirements.

[0071] Further, if Figure 2 As shown, a mounting hole is provided on the vertical plate 21, and the mounting hole extends along the vertical direction of the vertical plate 21. The adjustment component 23 is arranged in the mounting hole. The adjustment component 23 includes a moving block 231, a linkage block 232 and a pressing block 233, wherein:

[0072] The moving block 231 is arranged at one end of the width straightening mechanism 10 adjacent to the mounting hole and can move in the vertical direction. The moving block 231 is in the shape of a right triangle. One right-angled side of the moving block 231 is connected to the steel rolling roller 22. Preferably, an arc-shaped depression is arranged on one right-angled side of the moving block 231 to increase the contact area with the steel rolling roller 22, thereby ensuring the reliability of the connection between the moving block 231 and the steel rolling roller 22. The other right-angled side of the moving block 231 can abut against the inner surface of the mounting hole, so as to move up and down relative to the mounting hole under the guidance of the inner surface of the mounting hole.

[0073] The linkage block 232 is arranged in the mounting hole and can move in the horizontal direction. The first end of the linkage block 232 is provided with a first abutting inclined surface, and the second end of the linkage block 232 is provided with a second abutting inclined surface. In the present embodiment, the linkage block 232 is composed of two right triangles and a vertical beam connected between the two right triangles, wherein the hypotenuse of one right triangle constitutes the first abutting inclined surface, and the hypotenuse of the other right triangle constitutes the second abutting inclined surface, and the vertical beam can reciprocate in the mounting hole in the horizontal direction, and the first abutting inclined surface abuts against the hypotenuse of the moving block 231. Specifically, the hypotenuse of a right triangle of the linkage block 232 abuts against the hypotenuse of the moving block 231, and the hypotenuse of the right triangle and the hypotenuse of the moving block 231 can slide relative to each other.

[0074] The pressing block 233 is located at one end of the mounting hole away from the width straightening mechanism 10 and is fixedly connected to the mounting hole. The pressing block 233 is a right-angled triangle, and the second abutting inclined surface abuts against the hypotenuse of the pressing block 233, that is, the hypotenuse of another right-angled triangle of the linkage block 232 abuts against the hypotenuse of the pressing block 233, and the hypotenuse of the right-angled triangle can slide along the hypotenuse of the pressing block 233.

[0075] Specifically, if the thickness of the steel billet 100 is greater than the distance between the two rolling mill rollers 22, the steel billet 100 will push the rolling mill roller 22 above it to move upward, and the movement of the rolling mill roller 22 will drive the moving block 231 to move upward synchronously. The movement of the moving block 231 will push the linkage block 232 to move horizontally. Since the second abutting slope of the linkage block 232 abuts against the pressure block 233, under the restriction of the pressure block 233, the linkage block 232 can only move in the horizontal direction within a preset error range to ensure that the thickness of the steel plate remains roughly consistent during the steel rolling process.

[0076] Going further, Figure 2 As shown, the steel rolling roller 22 includes a steel plate roller 221 and a limiting roller 222, wherein:

[0077] The steel plate pressing roller 221 is rotatably connected to the corresponding moving block 231 through the first rotating shaft. Specifically, the steel plate pressing roller 221 is sleeved on the outside of the first rotating shaft and can rotate synchronously with the first rotating shaft. The two ends of the first rotating shaft are rotatably connected to the two corresponding moving blocks 231. The steel plate pressing roller 221 is configured to apply extrusion force to the steel billet 100, that is, the steel billet 100 passes between the two steel plate pressing rollers 221, and the steel plate pressing roller 221 directly contacts the steel billet 100.

[0078] The limiting pressure roller 222 is rotatably connected to the corresponding pressure block 233 through the second rotating shaft. Specifically, the limiting pressure roller 222 is sleeved on the outside of the second rotating shaft and can rotate synchronously with the second rotating shaft. The two ends of the second rotating shaft are rotatably connected to the two corresponding pressure blocks 233. The limiting pressure roller 222 is configured to apply an extrusion force to the steel plate pressure roller 221 to limit the deformation and transition displacement of the steel plate pressure roller 221.

[0079] In one embodiment of the present application, Figure 4 As shown, the driving assembly 13 includes a first adjusting rod, and the first adjusting rod includes a first threaded rod 131 and a first threaded tube 132 which are threadedly connected. The free end of the first threaded rod 131 (the end of the first threaded rod 131 that is not connected to the first threaded tube 132) is rotatably connected to the first straightening plate 11, and the first threaded rod 131 can drive the first straightening plate 11 to move synchronously. The free end of the first threaded tube 132 (the end of the first threaded tube 132 that is not connected to the first threaded rod 131) is fixedly connected to the second straightening plate 12. Through the threaded cooperation of the first threaded rod 131 and the first threaded tube 132, the first straightening plate 11 moves relative to the second straightening plate 12. The threaded connection method is simple and convenient, and it is easy to adjust the distance between the first straightening plate 11 and the second straightening plate 12.

[0080] Further, if Figure 3 As shown, the drive assembly 13 also includes a second adjusting rod, which is arranged side by side and at intervals with the first adjusting rod, and the second adjusting rod includes a second threaded rod 133 and a second threaded tube 134 connected by threads, the free end of the second threaded rod 133 (the end of the second threaded rod 133 that is not connected to the second threaded tube 134) is rotatably connected to the first straightening plate 11, and the free end of the second threaded tube 134 (the end of the second threaded tube 134 that is not connected to the second threaded rod 133) is fixedly connected to the second straightening plate 12, and the first straightening plate 11 moves relative to the second straightening plate 12 through the threaded cooperation between the second threaded rod 133 and the second threaded tube 134. The provision of the second threaded rod 133 not only improves the connection strength between the first straightening plate 11 and the second straightening plate 12, but also prevents the first straightening plate 11 and the second straightening plate 12 from being offset, thereby ensuring the accuracy of the width straightening mechanism 10 in straightening the steel billet 100.

[0081] Further, if Figure 5 As shown, the outer peripheral surface of the free end of the first threaded rod 131 is provided with a first annular protrusion 1311, and the bottom surface of the first straightening plate 11 is provided with a first clamping groove 111 clamped with the first annular protrusion 1311. Through the clamping cooperation between the first annular protrusion 1311 and the first clamping groove 111, the first threaded rod 131 can be rotatably connected to the first straightening plate 11, and the first threaded rod 131 can drive the first straightening plate 11 to move synchronously;

[0082] The outer peripheral surface of the free end of the second threaded rod 133 is provided with a second annular convexity, and the bottom surface of the first straightening plate 11 is provided with a second clamping groove which is clamped with the second annular convexity. Through the clamping cooperation between the second annular convexity and the second clamping groove, the second threaded rod 133 can be rotatably connected to the first straightening plate 11, and the second threaded rod 133 can drive the first straightening plate 11 to move synchronously.

[0083] The clamping connection is simple and convenient, so that the connection between the first straightening plate 11 and the first threaded rod 131 and the second threaded rod 133 becomes simple and convenient.

[0084] It should be noted that the connection method between the second threaded rod 133 and the first straightening plate 11 is not shown in the figure, but the connection method between the second threaded rod 133 and the first straightening plate 11 is the same as the connection method between the first threaded rod 131 and the first straightening plate 11. For details, please refer to Figure 5 shown.

[0085] Further, if Figure 3 As shown, the free end of the first threaded rod 131 horizontally extends out of the first straightening plate 11 to form a first extension portion 1312; the free end of the second threaded rod 133 horizontally extends out of the first straightening plate 11 to form a second extension portion 1331. The arrangement of the first extension portion 1312 and the second extension portion 1331 makes the operation of driving the first threaded rod 131 and the second threaded rod 133 to rotate simple and convenient.

[0086] In addition, when a motor is needed for large-scale adjustment, the first extension portion 1312 or the second extension portion 1331 is clipped onto the drive shaft of the motor through the cooperation of the bayonet and the connecting sleeve, and the threaded rod can be driven to rotate by the motor.

[0087] Going further, Figure 3 As shown, the drive assembly 13 further includes a synchronization device 135, and the synchronization device 135 includes a first gear ring 1351, a second gear ring 1352 and a transmission chain 1353, wherein:

[0088] The first gear ring 1351 is sleeved on the outside of the first extension part 1312. The first gear ring 1351 can be connected to the first extension part 1312 through a key, or can be made integrally with the first extension part 1312.

[0089] The second gear ring 1352 is sleeved on the outside of the second extension portion 1331. The second gear ring 1352 can be connected to the second extension portion 1331 through a key, or can be made integrally with the second extension portion 1331.

[0090] The transmission chain 1353 is sleeved between the first gear ring 1351 and the second gear ring 1352, and the transmission chain 1353 is configured to drive the first gear ring 1351 and the second gear ring 1352 to rotate synchronously. When only the first threaded rod 131 or the second threaded rod 133 is rotated, the two threaded rods can rotate synchronously through the synchronization device 135 to adjust the distance between the first straightening plate 11 and the second straightening plate 12, thereby making the adjustment operation simple and convenient.

[0091] Further, if Figure 5 As shown, the outer circumferential surface of the first extension portion 1312 is provided with a first annular groove 13121, and the outer circumferential surface of the second extension portion 1331 is provided with a second annular groove, and the first annular groove 13121 and the second annular groove are both configured to accommodate the transmission chain 1353. When there is no need to rotate the two threaded rods at the same time, the transmission chain 1353 is pushed into the first annular groove 13121 and the second annular groove, and the single first threaded rod 131 or the second threaded rod 133 can be adjusted to achieve high-precision fine-tuning.

[0092] It should be noted that the second annular groove structure is not shown in the figure, but the specific structure of the second annular groove is the same as that of the first annular groove 13121, so the specific structure of the first annular groove 13121 can be referred to. Figure 5 shown.

[0093] Further, if Figure 3 As shown, the synchronization device 135 also includes a support rod 1354 arranged inside the transmission chain 1353. Both ends of the support rod 1354 are equipped with tensioning wheels 1355 that mesh with the transmission chain 1353. The tensioning wheel 1355 can support the transmission chain 1353 to prevent the transmission chain 1353 from collapsing in the middle and affecting the synchronous transmission, and at the same time can reduce the deviation of the synchronous transmission.

[0094] It should be noted that, when in use, the support rod 1354 is placed on the table of the assembly line, and the support rod 1354 is supported by the table, so that the support rod 1354 can play a good supporting role for the transmission chain 1353.

[0095] Furthermore, the tensioning wheel 1355 includes a coaxially connected tensioning gear and a tensioning fixed pulley. When the two threaded rods need to be rotated simultaneously, the transmission chain 1353 engages with the tensioning gear. When the two threaded rods do not need to be rotated simultaneously, the transmission chain 1353 is supported by the tensioning fixed pulley. The specific structure of the tensioning gear and the tensioning fixed pulley is prior art and will not be repeated here.

[0096] In one embodiment of the present application, Figure 3 and Figure 6 As shown, the end of the first extension portion 1312 is clamped with the first screw cap 136. Specifically, the end of the first extension portion 1312 is provided with a first slot 13122, and the first screw cap 136 is provided with a first mounting hole. The inner surface of the first mounting hole is provided with a first ridge 1362.
