[0028] In the reversible rolling mill rolling process, the workpiece to be rolled (such as a steel billet) needs to be rolled back and forth and periodically flipped.

[0029] In related technologies, the reciprocating rolling and periodic flipping of the workpiece to be rolled require manual labor, which is not only inefficient but also cannot guarantee rolling accuracy and product quality.

[0030] To address the aforementioned problems, this disclosure provides a rolling system including a rolling mill and multiple fully automatic tilting feeders, wherein at least one rolling mill is equipped with a fully automatic tilting feeder on both sides, and two fully automatic tilting feeders are arranged symmetrically.

[0031] In one embodiment of this disclosure, the rolling mill is a reversible rolling mill.

[0032] In one embodiment of this disclosure, see [link to relevant documentation]. Figures 1-4 The fully automatic flipping feeding device includes a frame 1, a guide structure 2, a flipping component 3, and a clamping and feeding component 4.

[0033] The frame 1 provides support, the guide structure 2 is mounted on the frame 1 and has a feed channel 21 for passing the workpiece to be rolled, the flipping assembly 3 is sleeved on the outside of the guide structure 2, and the clamping and feeding assembly 4 is mounted on the flipping assembly 3. The clamping and feeding assembly 4 is used to clamp and feed the workpiece to be rolled, and the flipping assembly 3 is used to drive the clamping and feeding assembly 4 to rotate 90 degrees back and forth, thereby causing the workpiece to be rolled to rotate 90 degrees back and forth, realizing the automated periodic flipping of the workpiece to be rolled.

[0034] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 and Figure 2 The frame 1 includes a base (not shown in the base diagram) and two support portions mounted on the base. The two support portions are arranged sequentially along a first direction and are independently configured (in other words, the two support portions are spaced a certain distance apart; the two support portions are defined as the first support portion 11 and the second support portion 12). Both the first support portion 11 and the second support portion 12 are provided with annular fixing holes, which are coaxially arranged. The first support portion 11 is provided with a first annular fixing hole, and the second support portion 12 is provided with a second annular fixing hole. The diameter of the first annular fixing hole is smaller than the diameter of the second annular fixing hole.

[0035] The guide structure 2 has a guide body 22 and an extension plate 23, with the extension plate 23 disposed on the outside of one end of the guide body 22. In this embodiment, the extension plate 23 and the guide body 22 can be integrally formed, which facilitates manufacturing.

[0036] The guide body 22 has a through-passage channel 21 arranged along its axial direction inside. This allows the workpiece to be rolled to be conveyed within the passage 21, ensuring that the material's lateral reciprocating motion is without deviation, guaranteeing the guiding accuracy of the workpiece's reciprocating motion, maintaining the fixation of the workpiece's centerline, and ensuring stable operation of subsequent processes, thus meeting the requirements of high-precision rolling. Furthermore, the selection of the diameter of the passage 21 needs to ensure smooth material passage and avoidance of obstruction. Specifically, the axial direction of the passage 21 is...

[0037] In one example, the dimensions of the feed channel 21 are the same throughout. In another example, see... Figure 1 and Figure 2 Along the axial direction of the guide structure 2, the material passage 21 includes a material passage sub-channel 212 connected in sequence and two guide sub-channels 211 respectively connected to both ends of the material passage sub-channel 212. The diameters of the two guide sub-channels 211 gradually increase in the direction away from the material passage sub-channel 212. In other words, the two guide sub-channels 211 have a trumpet-shaped structure, and their smaller diameter ends are connected to the material passage sub-channel 212. In this disclosure, the material passage 21 with trumpet-shaped ends is more conducive to guiding the workpiece to be rolled, reducing the possibility of the workpiece failing to smoothly enter the fully automatic flip-feeding device due to positional deviation.

[0038] In one embodiment of this disclosure, after one end of the guide structure 2 passes through the first annular fixing hole and the second annular fixing hole in sequence, the extension plate 23 is placed on the side of the first support portion 11 away from the second support portion 12, and is fixed to the first support portion 11 by a plurality of bolts.

[0039] In one embodiment of this disclosure, the flipping assembly 3 includes a flipping drive member 31 and a flipping action member 32. The flipping action member 32 is sleeved on the outside of the guide structure 2 and is rotatably connected to the frame 1.

[0040] In one embodiment, the flipping member 32 is located between the second support portion 12 and the guide structure 2, and the outer wall of the flipping member 32 is rotatably connected to the inner wall of the second support portion 12 via a first bearing 5. In this embodiment, the flipping member 32 has a groove at the second support portion 12, and the second support portion 12 is embedded in the groove (in other words, the outer middle of the flipping member 32 has a groove, and the second support portion 12 is sleeved on the outer side of the flipping member 32 and located in the groove), thus reducing the size and cost of the entire device.

[0041] In this embodiment, see Figure 1 and Figure 2 The flipping action 32 may include a first sub-flipping action 321 and a second sub-flipping action 322 connected together. The exterior of the first sub-flipping action 321 has a double-layer stepped structure. It can be understood that the first sub-flipping action 321 has a small diameter end, a medium diameter end and a large diameter end connected in sequence. The small diameter end of the first sub-flipping action 321 is rotatably connected to the second support part 12 through the first bearing 5. The end face of the second sub-flipping action 322 is connected and fixed to the small diameter end of the first sub-flipping action 321, so that the entire flipping action 32 can achieve overall rotational movement.

[0042] A first stepped surface is formed between the small-diameter end and the medium-diameter end, and a second stepped surface is formed between the medium-diameter end and the large-diameter end. The second support part 12 has a third stepped surface inside, which is correspondingly arranged with the second stepped surface. One end of the inner ring of the first bearing 5 abuts against the second stepped surface, and one end of the outer ring of the first bearing 5 abuts against the third stepped surface. The other end of the outer ring of the first bearing 5 is fixed to the second support part 12 by an end cap. The other end of the inner ring of the first bearing 5 abuts against the second sub-rotating member 322 (the length of the small-diameter end of the first sub-rotating member 321 is greater than the length of the first bearing 5, and the second sub-rotating member 322 has a protrusion that is embedded between the end cap and the small-diameter end of the first sub-rotating member 321 and abuts against the other end of the inner ring of the first bearing 5). Thus, through the combined cooperation of the second stepped surface, the third stepped surface, the end cap, and the protrusion of the second sub-rotating member 322, the first bearing 5 is fixed and limited along the axial direction of the guide structure 2.

[0043] In this embodiment, a labyrinth-type sealing structure is used between the first stepped surface of the first sub-flipping member 321 and the second support portion 12, and an oil seal is used to reinforce the seal. Similarly, a labyrinth-type sealing structure is used between the second sub-flipping member 322 and the second support portion 12, and an oil seal is used to reinforce the seal. It can be understood that the two side walls of the groove are sealed to the second support portion 12 through a labyrinth-type sealing structure, and an oil seal is used to reinforce the seal. In this disclosure, grease lubrication is used, simplifying maintenance.

[0044] In this embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4 The tilting drive 31 includes a rotary reducer 312 and a drive motor 311. The rotary reducer 312 is sleeved on the outside of the guide structure 2, and its fixed end is connected to the first support part 11. The power output end of the rotary reducer 312 is bolted to the first sub-tilting member 321 of the tilting member 32. The drive motor 311 is mounted on the frame 1 (for example, the drive motor 311 is mounted on the first support part 11), and its output end is connected to the power input end of the rotary reducer 312. In this disclosure, rotational power is input to the power input end of the rotary reducer 312 through the drive motor 311, and then the rotary reducer 312 drives the tilting member 32 to rotate around the guide structure 2.

[0045] In one embodiment of this disclosure, the drive motor 311 can be a servo motor, which has high control precision and good stability.

[0046] In one embodiment of this disclosure, the drive motor 311 can control the rotary reducer 312 to output a reciprocating rotational motion of 0-90 degrees (rotating 90 degrees when the workpiece to be rolled is clamped, and returning to 0 degrees when the workpiece is not clamped), achieving high-precision control (for example, the drive motor 311 can control the rotation time of the rotary reducer 312 to not exceed 3 seconds, and the reciprocating positioning accuracy can be within ±0.2°). It is understood that in this disclosure, the workpiece to be rolled needs to be rotated 90 degrees before being output to the next rolling process.

[0047] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 4 The clamping and feeding assembly 4 includes a clamping drive 41, two sets of support structures 42, and two clamping and feeding components 43. The two clamping and feeding components 43 correspond one-to-one with the two sets of support structures 42. The two sets of support structures 42 are distributed on both sides of the guide structure 2 and are symmetrically arranged along the central axis of the guide structure 2. One end of the support structure 42 is rotatably connected to the flipping action 32, and the other end is provided with the clamping and feeding component 43. The clamping drive 41 is connected to the support structure 42. The clamping drive 41 is configured to drive the two support structures 42 to rotate, so that the two clamping and feeding components 43 move closer to each other to clamp and feed the workpiece to be rolled, or move away from each other. The clamping and feeding components 43 are configured to clamp and feed the workpiece to be rolled when they move closer to each other.

[0048] In one implementation, see Figure 1 , Figure 2 and Figure 4 The flipping action 32 has two sets of fixing plates corresponding to the two support structures 42 respectively. Each set of fixing plates has two fixing plates 323 (for example, the two fixing plates 323 are fixed to the second sub-flipping action 322). The arrangement direction of the two fixing plates 323 is perpendicular to the axis of the guide structure 2. The support structure 42 is located between the two fixing plates 323, and the two sides of the first end of the support structure 42 are rotatably connected to the two fixing plates 323 respectively. The two sides of the second end of the support structure 42 have connecting plates 421. The clamping feeding member 43 is set on the connecting plate 421. The clamping drive member 41 is configured to drive the two support structures 42 to rotate, so that the two clamping feeding members 43 move closer to each other to clamp and transport the workpiece to be rolled, or move away from each other, so as to achieve the centering and clamping of the workpiece to be rolled.

[0049] In one embodiment of this disclosure, the clamping drive member 41 may include two sets of support drive members 411, which correspond one-to-one with two sets of support structures 42. The two sets of support drive members 411 simultaneously drive the two sets of clamping feed members 43 to move closer to or further away from each other. The fixed end of the support drive member 411 is hinged to the flipping action member 32, and the power output end is hinged to the support structure 42.

[0050] In another embodiment of this disclosure, see Figure 1 and Figure 2 The clamping drive unit 41 includes a support drive unit 411 and at least one set of meshing gear pairs 412. The fixed end of the support drive unit 411 is hinged to the flipping action unit 32 (e.g., hinged to the first sub-flipping action unit 321), and the output end is hinged to one of the support structures 42. The meshing gear pairs 412 are disposed on one side of the support structures 42, and each pair includes two meshing gears symmetrically arranged along the centerline of the guide structure 2. Each gear corresponds one-to-one with one of the two support structures 42. Both ends of the support structures 42 are rotatably connected to the corresponding fixed plates 323 via rotating shafts. The rotating shafts pass through the fixed plates 323 and connect to the corresponding gears, thereby driving the two support structures 42 to rotate using one support drive unit 411 through the meshing gear pairs 412.

[0051] In this disclosure, a support drive 411 is used to drive one of the support structures 42 to rotate, and to drive the gear connected to the support structure 42 to rotate. The meshing action of the two gears drives the other support structure 42 to rotate. Thus, the support drive 411 is used to achieve the mutual approach and distance of the two clamping and feeding parts 43. The cost is low. Furthermore, the meshing action of the meshing gears 412 can also be used to ensure the consistency of movement (clamping synchronization) of the two clamping and feeding parts 43, thereby improving the stability of the entire clamping and feeding process.

[0052] In one example, the support drive 411 is a hydraulic cylinder. In other examples, the support drive 411 may also be other structures not shown.

[0053] In one embodiment of this disclosure, the number of meshing gear pairs 412 is one.

[0054] In one embodiment of this disclosure, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 4 The clamping and feeding component 43 includes a clamping roller 431 and a clamping drive component 432. Both ends of the clamping roller 431 are rotatably connected to two connecting plates 421 of the support structure 42, and one end of the roller extends through the connecting plate 421 and connects to the output end of the clamping drive component 432. The fixed end of the clamping drive component 432 is disposed on the corresponding connecting plate 421. The clamping drive component 432 is configured to drive the clamping roller 431 to rotate and feed material. In this disclosure, the clamping roller 431 is used to clamp the workpiece to be rolled, and in conjunction with the clamping drive component 432, it performs reciprocating feeding of the workpiece to be rolled.

[0055] In this embodiment, the two clamping drive members 432 are distributed on both sides of the clamping roller 431, so that interference between the two clamping drive members 432 can be avoided.

[0056] In one embodiment of this disclosure, the clamping drive 432 can be a hydraulic motor.

[0057] The clamping and feeding assembly 4 in this disclosure can clamp workpieces of different sizes to be rolled (e.g., it can clamp workpieces with a width between 10-300mm), and the support drive 411 can quickly clamp the workpieces to be rolled in a short time (e.g., the action time of the support drive 411 can be controlled to within 1 second). The maximum working pressure of the support drive 411 can be limited according to actual needs (e.g., the maximum working pressure can be 30Mpa, 25Mpa, 20Mpa, 16Mpa, etc.).

[0058] In this disclosure, the dimensions of the pinch roller 431 can be set according to actual needs (for example, the diameter of the pinch roller 431 can be 220mm and the length can be 250mm). The pinching drive 432 can adjust the rotation speed of the pinch roller 431 according to actual needs (for example, when the feed speed of the workpiece to be rolled is 0.6–1m / s, the rotation speed of the pinch roller 431 can be 0–1.5m / s; the pinching drive 432 of this disclosure can achieve stepless speed regulation, the acceleration speed is controllable, and the maximum acceleration and deceleration can reach 1.5m / s²). The clamping and feeding assembly 4 in this disclosure has a fast response and can achieve stable conveying of the workpiece to be rolled, so that the conveying speed of the workpiece to be rolled in the fully automatic flipping feeding device is precisely matched with the rolling cycle of the rolling system. Furthermore, the clamping and feeding assembly 4 uses the pinch roller 431 for clamping, and the clamping force is stable and reliable, without damaging the surface of the workpiece to be rolled.

[0059] In one embodiment of this disclosure, the fully automatic tilting and feeding device further includes a control module. This control module is electrically connected to the drive motor 311, the support drive component 411, and the clamping drive component 432, and is used to control the operation of the entire fully automatic tilting and feeding device (achieving automatic control of the timing of clamping, feeding, and tilting actions). Simultaneously, this control module can also be linked with the control terminal of the rolling mill to achieve precise matching of the operating rhythm of the fully automatic tilting and feeding device with the rolling process, realizing fully automatic integrated clamping, feeding, and tilting operations.

[0060] The use of the fully automatic tilting feeder in this disclosure includes: When there is no workpiece to be rolled in the fully automatic flipping feeding device, the two clamping rollers 431 are controlled to move away from each other and are in a state of distance (i.e., not clamping and feeding). When the workpiece to be rolled is transported to the fully automatic flipping feeding device, the clamping drive 41 controls the two clamping rollers 431 to move closer to each other and clamp the workpiece to be rolled. At the same time, the clamping drive 432 controls the clamping rollers 431 to rotate and feed the workpiece. After clamping is completed, the drive motor 311 controls the flipping action 32 through the rotary reducer 312 to drive the entire clamping and feeding assembly 4 to rotate 90 degrees. At this time, the workpiece to be rolled held by the clamping roller 431 also flips 90 degrees. The feeding process continues until the workpiece to be rolled leaves the fully automatic flipping feeding device. Then, the clamping and feeding assembly 4 is restored to its initial state for the next use.

[0061] The fully automatic tilting and feeding device disclosed herein integrates automatic clamping, feeding, and tilting functions. It utilizes meshing gears 412 to achieve synchronous clamping of the workpiece by two clamping rollers 431, improving feeding accuracy. A drive motor 311, in conjunction with a rotary reducer 312, achieves high-precision positioning. The operating rhythm of the fully automatic tilting and feeding device used in this disclosure can be adjusted according to the rolling progress, achieving a high degree of matching between the operating rhythm of the fully automatic tilting and feeding device and the rolling progress, ensuring rolling accuracy and product quality. Furthermore, the fully automatic tilting and feeding device disclosed herein can meet the needs of high-speed, high-precision, and automated rolling systems. It requires no manual intervention, has a compact structure, precise operation, and stable operation, significantly improving the automation level and rolling accuracy of reversible rolling mill production lines. It is suitable for automatic tilting and feeding operations of multi-specification steel billets.
