Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a hot rolling width-fixing device. Background Technology

[0002] Metal processing involves multiple processes, with hot rolling being a crucial one. Hot rolling refers to the rolling process performed above the recrystallization temperature of the metal. Hot rolling improves the processing performance of metals and alloys by breaking down coarse grains in the casting state, significantly healing cracks, reducing or eliminating casting defects, transforming the as-cast structure into a deformable structure, and enhancing the metal's processing properties. During hot rolling, the metal material needs to be rolled to the corresponding dimensions according to the design requirements of different products. Therefore, width limitation is necessary during hot rolling. Current hot rolling equipment has fixed width limiting plates on both sides, only accommodating one width. For example, the steel processing hot rolling equipment disclosed in patent CN218191716U has fixed limiting plates, resulting in low overall applicability. When dealing with rolled parts of different widths, the limiting components need to be replaced and reinstalled. Repeatedly replacing the limiting components is cumbersome, time-consuming, and affects production efficiency. Utility Model Content

[0003] To solve the above problems, this utility model provides a hot rolling width-fixing device.

[0004] This utility model is achieved using the following solution:

[0005] A hot-rolled width-fixing device includes a conveying mechanism, a first limiting mechanism and a second limiting mechanism respectively disposed on both sides of the conveying mechanism, a first driving mechanism for driving the first limiting mechanism to move toward the second limiting mechanism, and a second driving mechanism for driving the second limiting mechanism to move toward the first limiting mechanism. Each of the first and second limiting mechanisms includes a base, a width limiting member movably connected to the base, a width adjusting assembly disposed on the base, and a guide assembly disposed on the base. The width adjusting assembly includes a cam, an adjusting ring sleeved outside the cam, an adjusting bracket disposed on the outer wall of the adjusting ring, and an adjusting wheel disposed on the adjusting bracket. The adjusting wheel is connected to the width limiting member. The cam of the first limiting mechanism is driveably connected to the first driving mechanism, and the cam of the second limiting mechanism is driveably connected to the second limiting mechanism.

[0006] Furthermore, both the first drive mechanism and the second drive mechanism include a support plate, a drive motor disposed on the support plate, a transmission gear set connected to the output end of the drive motor, and a transmission rod with one end connected to the transmission gear set, the other end of the transmission rod being connected to the cam.

[0007] Furthermore, the transmission rod and the transmission gear set, as well as the transmission rod and the cam, are connected by universal joints.

[0008] Furthermore, a transmission component is provided on the side of the width limiting member away from the conveying mechanism, and the transmission component is provided with an inner recess that matches the adjusting wheel; the guide assembly is connected to the transmission component.

[0009] Furthermore, the guide assembly includes a guide bracket disposed on the base, a guide rod disposed on the guide bracket, and a spring sleeved on the guide rod, one end of the spring being connected to the end of the guide rod and the other end of the spring being connected to the guide bracket.

[0010] Furthermore, the width limiting member has an inclined surface, and the width limiting member of the first limiting mechanism and the width limiting member of the second limiting mechanism form a flared opening.

[0011] Furthermore, the conveying mechanism includes a conveying frame and a set of conveying rollers disposed on the conveying frame.

[0012] Furthermore, the hot rolling width-fixing device also includes a pressing mechanism, which includes a first pressing frame and a second pressing frame disposed on the conveying mechanism, and a pressing roller connected between the first pressing frame and the second pressing frame. Specifically, both the first pressing frame and the second pressing frame are provided with adjusting screws for adjusting the height of the pressing roller.

[0013] Furthermore, there are two pressing mechanisms.

[0014] Furthermore, the hot rolling width-fixing device also includes a vision component, which includes a vision bracket disposed on one side of the conveying mechanism and a vision sensor disposed on the vision bracket.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The first and second limiting mechanisms of this utility model can change their spacing under the drive of the first and second driving mechanisms, respectively. Thus, during the hot rolling process, the spacing can be quickly adjusted according to the width of the workpiece being processed, eliminating the need for repeated disassembly and assembly, simplifying the operation, improving work efficiency, and enhancing the adaptability of the hot rolling equipment.

Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Example 1

[0025] Reference Figure 1-4 This utility model provides a hot-rolled width-fixing device, including a conveying mechanism 1, a first limiting mechanism 2 and a second limiting mechanism 3 respectively disposed on both sides of the conveying mechanism 1, a first driving mechanism 4 for driving the first limiting mechanism 2 to move toward the second limiting mechanism 3, and a second driving mechanism 5 for driving the second limiting mechanism 3 to move toward the first limiting mechanism 2. Under the drive of the first driving mechanism 4 and the second driving mechanism 5, the distance between the first limiting mechanism 2 and the second limiting mechanism 3 can be changed, and the hot-rolled workpiece passes between the first limiting mechanism 2 and the second limiting mechanism 3. The width of the hot-rolled workpiece can be determined by adjusting the distance between the first limiting mechanism 2 and the second limiting mechanism 3.

[0026] Both the first limiting mechanism 2 and the second limiting mechanism 3 include a base 21, a width limiting member 22 movably connected to the base 21, a width adjusting component 23 disposed on the base 21, and a guide component 24 disposed on the base 21. The width adjusting component 23 includes a cam 231, an adjusting ring 232 sleeved outside the cam 231, an adjusting bracket 233 disposed on the outer wall of the adjusting ring 232, and an adjusting wheel 234 disposed on the adjusting bracket 233. The adjusting wheel 234 is connected to the width limiting member 22. The cam 231 of the first limiting mechanism 2 is drive-connected to the first driving mechanism 4, and the cam 231 of the second limiting mechanism 3 is drive-connected to the second limiting mechanism 3. The cam 231 and the adjusting ring 232 can rotate relative to each other. When the cam 231 rotates, since the adjusting wheel 234 is connected to the width limiting member 22, the adjusting ring 232 does not rotate relative to the cam 231. At this time, the adjusting ring 232 is pushed by the cam 231 towards the width limiting member 22, thereby pushing the width limiting member 22 to move. In this embodiment, two width adjusting components 23 are provided, which can push the width limiting member 22 from two positions to ensure the smoothness of the adjustment process. At the same time, two corresponding transmission rods of the drive mechanism are also provided.

[0027] Both the first driving mechanism 4 and the second driving mechanism 5 include a support plate 41, a driving motor 42 mounted on the support plate 41, a transmission gear set 43 connected to the output end of the driving motor 42, and a transmission rod 44 with one end connected to the transmission gear set 43, the other end of which is connected to the cam 231. When the driving motor 42 is working, the transmission rod 44 drives the cam 231 to rotate, thereby adjusting the position of the width limiting member 22. Of course, the transmission gear set 43 in the attached drawings of this embodiment is only schematic; in specific implementations, a gearbox or other transmission structure can also be used depending on the requirements. In addition, during use, the support plate 41 can be connected and fixed to a separately provided support frame.

[0028] The transmission rod 44 and the transmission gear set 43, as well as the transmission rod 44 and the cam 231, are connected by universal joints 45.

[0029] A transmission component 25 is provided on the side of the width limiting member 22 away from the conveying mechanism 1. The transmission component 25 has a recessed portion 26 that matches the adjusting wheel 234. The guide assembly 24 is connected to the transmission component 25. Specifically, the adjusting wheel 234 is inserted into the recessed portion 26. Since two width adjusting assemblies 23 are provided in this embodiment, two corresponding recessed portions 26 are provided. In addition, in specific implementations, a cylinder, hydraulic rod, or other driving component can also be provided on the base 21. The output end of the driving component is connected to the transmission component 25 to apply force to the width limiting member 22 when needed.

[0030] The guide assembly 24 includes a guide bracket 241 disposed on the base 21, a guide rod 242 disposed on the guide bracket 241, and a spring 243 sleeved on the guide rod 242. One end of the spring 243 is connected to the end of the guide rod 242, and the other end of the spring 243 is connected to the guide bracket 241. The cooperation between the guide rod 242 and the guide bracket 241 makes the movement of the width limiting member 22 smoother. When the adjusting ring 232 moves away from the width limiting member 22, the spring 243 can push the guide rod 242 to reset, that is, the width limiting member 22 also moves away from the conveying mechanism 1 under the push of the spring 243. In this embodiment, two guide assemblies 24 are provided to ensure the smoothness of movement.

[0031] The width limiting member 22 has an inclined surface 27. The width limiting member 22 of the first limiting mechanism 2 and the width limiting member 22 of the second limiting mechanism 3 form a flared opening, facilitating the hot-rolled workpiece to enter between the two width limiting members 22. (See attached...) Figure 1 Taking the perspective of [the location] as an example, the horn-shaped opening is located on the rear side.

[0032] The conveying mechanism 1 includes a conveying frame 11 and a conveying roller group 12 disposed on the conveying frame 11. The conveying roller group 12 includes a plurality of evenly arranged conveying rollers.

[0033] The hot rolling width-fixing device further includes a pressing mechanism 6. The pressing mechanism 6 includes a first pressing frame 61 and a second pressing frame 62 mounted on the conveying mechanism 1, and a pressing roller 63 connected between the first pressing frame 61 and the second pressing frame 62. Both the first pressing frame 61 and the second pressing frame 62 are equipped with adjusting screws 64 for adjusting the height of the pressing roller 63. Both the first pressing frame 61 and the second pressing frame 62 are also equipped with adjusting blocks. The end of the pressing roller 63 is connected to the adjusting block, and the adjusting block is connected to the adjusting screw 64. The height is adjusted by adjusting the screw 64. The pressing mechanism 6 is located above the conveying roller group 12 and cooperates with the conveying roller group 12 to limit the hot-rolled workpiece in the vertical direction, preventing the hot-rolled workpiece from warping.

[0034] In this embodiment, there are two pressing mechanisms 6, one of which is located on the front side of the width limiting member 22 and the other is located on the rear side of the width limiting member 22.

[0035] Example 2

[0036] This utility model provides a hot-rolled width-fixing device, including a conveying mechanism 1, a first limiting mechanism 2 and a second limiting mechanism 3 respectively disposed on both sides of the conveying mechanism 1, a first driving mechanism 4 for driving the first limiting mechanism 2 to move toward the second limiting mechanism 3, and a second driving mechanism 5 for driving the second limiting mechanism 3 to move toward the first limiting mechanism 2. Under the drive of the first driving mechanism 4 and the second driving mechanism 5, the distance between the first limiting mechanism 2 and the second limiting mechanism 3 can be changed, and the hot-rolled workpiece passes between the first limiting mechanism 2 and the second limiting mechanism 3. The width of the hot-rolled workpiece can be determined by adjusting the distance between the first limiting mechanism 2 and the second limiting mechanism 3.

[0037] Both the first limiting mechanism 2 and the second limiting mechanism 3 include a base 21, a width limiting member 22 movably connected to the base 21, a width adjusting component 23 disposed on the base 21, and a guide component 24 disposed on the base 21. The width adjusting component 23 includes a cam 231, an adjusting ring 232 sleeved outside the cam 231, an adjusting bracket 233 disposed on the outer wall of the adjusting ring 232, and an adjusting wheel 234 disposed on the adjusting bracket 233. The adjusting wheel 234 is connected to the width limiting member 22. The cam 231 of the first limiting mechanism 2 is drive-connected to the first driving mechanism 4, and the cam 231 of the second limiting mechanism 3 is drive-connected to the second limiting mechanism 3. The cam 231 and the adjusting ring 232 can rotate relative to each other. When the cam 231 rotates, since the adjusting wheel 234 is connected to the width limiting member 22, the adjusting ring 232 does not rotate relative to the cam 231. At this time, the adjusting ring 232 is pushed by the cam 231 towards the width limiting member 22, thereby pushing the width limiting member 22 to move. In this embodiment, two width adjusting components 23 are provided, which can push the width limiting member 22 from two positions to ensure the smoothness of the adjustment process. At the same time, two corresponding transmission rods of the drive mechanism are also provided.

[0038] Both the first driving mechanism 4 and the second driving mechanism 5 include a support plate 41, a driving motor 42 mounted on the support plate 41, a transmission gear set 43 connected to the output end of the driving motor 42, and a transmission rod 44 with one end connected to the transmission gear set 43, the other end of which is connected to the cam 231. When the driving motor 42 is working, the transmission rod 44 drives the cam 231 to rotate, thereby adjusting the position of the width limiting member 22. Of course, the transmission gear set 43 in the attached drawings of this embodiment is only schematic; in specific implementations, a gearbox or other transmission structure can also be used depending on the requirements. In addition, during use, the support plate 41 can be connected and fixed to a separately provided support frame.

[0039] The transmission rod 44 and the transmission gear set 43, as well as the transmission rod 44 and the cam 231, are connected by universal joints 45.

[0040] A transmission component 25 is provided on the side of the width limiting member 22 away from the conveying mechanism 1. The transmission component 25 has a recessed portion 26 that matches the adjusting wheel 234. The guide assembly 24 is connected to the transmission component 25. Specifically, the adjusting wheel 234 is inserted into the recessed portion 26. Since two width adjusting assemblies 23 are provided in this embodiment, two corresponding recessed portions 26 are provided. In addition, in specific implementations, a cylinder, hydraulic rod, or other driving component can also be provided on the base 21. The output end of the driving component is connected to the transmission component 25 to apply force to the width limiting member 22 when needed.

[0041] The guide assembly 24 includes a guide bracket 241 disposed on the base 21, a guide rod 242 disposed on the guide bracket 241, and a spring 243 sleeved on the guide rod 242. One end of the spring 243 is connected to the end of the guide rod 242, and the other end of the spring 243 is connected to the guide bracket 241. The cooperation between the guide rod 242 and the guide bracket 241 makes the movement of the width limiting member 22 smoother. When the adjusting ring 232 moves away from the width limiting member 22, the spring 243 can push the guide rod 242 to reset, that is, the width limiting member 22 also moves away from the conveying mechanism 1 under the push of the spring 243. In this embodiment, two guide assemblies 24 are provided to ensure the smoothness of movement.

[0042] The width limiting member 22 has an inclined surface 27. The width limiting member 22 of the first limiting mechanism 2 and the width limiting member 22 of the second limiting mechanism 3 form a flared opening, facilitating the hot-rolled workpiece to enter between the two width limiting members 22. (See attached...) Figure 1 Taking the perspective of [the location] as an example, the horn-shaped opening is located on the rear side.

[0043] The conveying mechanism 1 includes a conveying frame 11 and a conveying roller group 12 disposed on the conveying frame 11. The conveying roller group 12 includes a plurality of evenly arranged conveying rollers.

[0044] The hot rolling width-fixing device further includes a pressing mechanism 6. The pressing mechanism 6 includes a first pressing frame 61 and a second pressing frame 62 mounted on the conveying mechanism 1, and a pressing roller 63 connected between the first pressing frame 61 and the second pressing frame 62. Both the first pressing frame 61 and the second pressing frame 62 are equipped with adjusting screws 64 for adjusting the height of the pressing roller 63. Both the first pressing frame 61 and the second pressing frame 62 are also equipped with adjusting blocks. The end of the pressing roller 63 is connected to the adjusting block, and the adjusting block is connected to the adjusting screw 64. The height is adjusted by adjusting the screw 64. The pressing mechanism 6 is located above the conveying roller group 12 and cooperates with the conveying roller group 12 to limit the hot-rolled workpiece in the vertical direction, preventing the hot-rolled workpiece from warping.

[0045] In this embodiment, there are two pressing mechanisms 6, one of which is located on the front side of the width limiting member 22 and the other is located on the rear side of the width limiting member 22.
