Description

Technical Field

[0001] This utility model relates to the field of shelving beam rolling mill technology, and in particular to a beam rolling mill with adjustable width. Background Technology

[0002] In the field of profile processing, rolling mills are key equipment for profile forming, using rolls to press raw materials to obtain profiles with specific cross-sectional shapes. However, the rolling mechanisms of existing profile rolling mills are typically fixed structures, making it difficult to flexibly adjust the spacing between the rolls according to actual production needs. When processing profiles of different widths, it is often necessary to replace the entire roll assembly or adjust the overall structure of the equipment. This not only increases the investment cost and storage space of the equipment but also prolongs production preparation time. Frequent disassembly and assembly operations can also affect the stability and processing accuracy of the equipment, reducing production efficiency. For scenarios requiring multi-variety, small-batch production, this limitation of traditional rolling mills significantly restricts production flexibility, making it difficult to quickly respond to the diverse market demands for profiles of different widths, thereby increasing the operating costs of manufacturing enterprises.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0058] Please see Figures 1 to 7 As shown, this utility model provides a beam rolling mill with adjustable width, comprising a machine body 1, on which a material guiding mechanism 2, a roll forming mechanism 3, a cutting mechanism 4, and a material support table 5 are sequentially arranged along its length; wherein:

[0059] The material guiding mechanism 2 is located at one end of the machine body 1 and is used to guide and limit the rolled material before it is rolled into shape.

[0060] The roll forming mechanism 3 includes a drive box 31, a fixed wheel set 32, a movable wheel set 33, and an adjustment component 34. The drive box 31 extends along the length of the machine body 1 and is disposed on one side of the machine body 1. The fixed wheel set 32 ​​is disposed close to the drive box 31 and is drivenly connected to the drive box 31. The movable wheel set 33 is movably mounted on the machine body 1 via the adjustment component 34 and is drivenly connected to the fixed wheel set 32. The movable wheel set 33 and the fixed wheel set 32 ​​cooperate to roll the rolled material. The adjustment component 34 is used to adjust the distance between the movable wheel set 33 and the fixed wheel set 32 ​​to adapt to the processing of rolled materials of different widths.

[0061] The cutting mechanism 4, installed on the other end of the machine body 1, is used to cut the rolled product to a preset length.

[0062] The material support platform 5 is used to support the cut product.

[0063] In actual production, the operation process is as follows: First, the worker adjusts the roll forming mechanism 3 according to the width of the rolled material to be processed and the forming width of the target beam product. The moving wheel set 33 is moved by the adjusting component 34, thereby changing the distance between the moving wheel set 33 and the fixed wheel set 32 ​​to ensure it matches the width of the rolled material. Then, the rolled material is installed on the coil support 413, and the lead end of the rolled material is guided to the guiding mechanism 2 by manual or mechanical traction. After being limited and guided by the guiding mechanism 2, it is fed into the roll forming mechanism 3. After the equipment starts, the drive box 31 of the roll forming mechanism 3 drives the fixed wheel set 32 ​​to rotate. The fixed wheel set 32 ​​synchronously drives the moving wheel set 33 to work together, completing the rolling forming operation while conveying the rolled material. One end of the rolled profile is continuously conveyed to the cutting mechanism 4. The cutting mechanism 4 precisely cuts the formed profile according to the preset product length. The cut product is then temporarily stored on the material support table 5.

[0064] This adjustable-width beam mill forms a complete profile processing flow through a guide mechanism 2, a roll forming mechanism 3, a cutting mechanism 4, and a support platform 5 arranged sequentially on the machine body 1. The roll forming mechanism 3 is the core component for achieving width adjustment. Its fixed wheel set 32 ​​and movable wheel set 33 work together to roll and form the profile. The adjustment component 34 can drive the movable wheel set 33 closer to or further away from the fixed wheel set 32, thereby changing the width between them to accommodate profiles of different widths. The guide mechanism 2 guides and limits the profile before it enters the roll forming mechanism 3, ensuring processing stability. The cutting mechanism 4 cuts the formed profile to a preset length, and the support platform 5 supports the cut product. This adjustable-width beam mill, by adjusting the wheel spacing through the adjustment component 34, overcomes the limitations of a fixed structure, improves equipment adaptability, reduces equipment investment and preparation time, ensures processing continuity and quality, enhances production flexibility, and reduces operating costs.

[0065] In this embodiment, the material to be processed is a C-groove crossbeam. An electrical control box 6 is located on one side of the machine body 1. This control box 6 is connected to the drive box 31 of the roll forming mechanism 3 and the cutting mechanism 4. The control principle and connection structure are existing technologies and will not be elaborated here. The drive box 31 of the roll forming mechanism 3 is equipped with a drive transmission structure, using a motor gear transmission structure commonly used in crossbeam rolling mills. The fixed wheel set 32 ​​and the movable wheel set 33 are mirror-symmetrically distributed. Their detailed structures follow the existing wheel set structure of roll forming machines, except that the movable wheel set 33 is installed on the machine body 1 via an adjustment component 34, which uses a screw drive structure. Correspondingly, the material guiding mechanism 2 also adopts a width-adjustable structure. The cutting mechanism 4 uses an existing tracking cutting mechanism 4, which can automatically complete the product cutting operation according to a preset length. The material support table 5 serves as the platform at the end of the machine body 1. Its height is the same as the rolling surface height of the rolling forming mechanism 3, and its surface is equipped with sliding rollers so that the product can slide smoothly on the material support table 5.

[0066] Please see Figure 1 and Figure 4 As shown, the fixed wheel assembly 32 includes a fixed frame 321 and several sets of first upper pressure wheels 322 and first lower pressure wheels 323 arranged vertically and vertically. The fixed frame 321 is fixedly installed on the machine body 1. The several sets of first upper pressure wheels 322 and first lower pressure wheels 323 are arranged at equal intervals along the length direction of the fixed frame 321. The first upper pressure wheel 322 is movably connected to the upper end of the fixed frame 321 through a first bearing seat 324, and the first lower pressure wheel 323 is rotatably installed at the lower end of the fixed frame 321 through a bearing. In this embodiment, the installation method of the first upper pressure wheel 322 and the first lower pressure wheel 323 on the fixed frame 321 is the prior art. It is worth noting that the first bearing seat 324 is provided with a sliding groove, which forms a sliding connection with the fixed frame 321. The top of the first bearing seat 324 is connected to a third adjusting screw 325, which is threadedly connected to the top of the fixed frame 321. By turning the third adjusting screw 325, the lifting height of the first upper pressure roller 322 can be adjusted, thereby changing the distance and pressure between the first upper pressure roller 322 and the first lower pressure roller 323 to adapt to the processing requirements of rolled materials of different thicknesses.

[0067] Several synchronously rotating drive shafts 311 extend from the side of the drive housing 31 near the fixed wheel assembly 32. Several first pressing wheels 323 are respectively fixedly sleeved on the several drive shafts 311, and a first sliding groove 3111 is provided on the outer side of one end of each of the several drive shafts 311. In this embodiment, the first pressing wheel 323 is interference-fitted with the drive shaft 311, and the first sliding groove 3111 is set as a long groove along the axial direction of the drive shaft 311 and is located at the end of the drive shaft 311 away from the first pressing wheel 323.

[0068] The first upper pressure roller 322 is connected to a connecting shaft 326 parallel to the drive shaft 311, and a second sliding groove 3261 is provided on the outer side of one end of the connecting shaft 326. In this embodiment, the second sliding groove 3261 is configured as an elongated groove along the axial direction of the connecting shaft 326 and is located at the end of the connecting shaft 326 away from the first upper pressure roller 322.

[0069] The first lower pressure roller 323 is driven to rotate by the drive shaft 311 of the drive box 31. When the first lower pressure roller 323 rotates, the rolled material is conveyed to the cutting mechanism 4 by friction and pressure between it and the first upper pressure roller 322. The first upper pressure roller 322 is driven to rotate by pressure and friction, thereby realizing the rolling and conveying of the rolled material.

[0070] Please see Figures 1 to 3 As shown, the movable wheel assembly 33 includes a movable frame 331 and several sets of second upper pressure wheels 332 and second lower pressure wheels 333 arranged vertically. The movable frame 331 is movably mounted on the machine body 1 via an adjustment assembly 34. The second upper pressure wheels 332 are movably mounted on the upper end of the movable frame 331 via a second bearing seat 334, and the second lower pressure wheels 333 are rotatably mounted on the lower end of the movable frame 331 via a bearing. In this embodiment, the installation method of the second upper pressure wheels 332 and the second lower pressure wheels 333 on the movable frame 331 is the prior art. It is worth noting that the second bearing seat 334 is also provided with a sliding groove, which forms a sliding connection with the movable frame 331. The top of the second bearing seat 334 is connected to a fourth adjusting screw 335, which is threadedly connected to the top of the movable frame 331. By turning the fourth adjusting screw 335, the lifting height of the second upper pressure roller 332 can be adjusted, thereby changing the distance and pressure between the second upper pressure roller 332 and the second lower pressure roller 333, so as to adapt it to the fixed roller group 32 and meet the processing requirements of rolled materials of different thicknesses.

[0071] The second pressing wheel 333 is sleeved on one end of the drive shaft 311 where the first sliding groove 3111 is provided, and a first pin 3331 is provided on it to be inserted into the first sliding groove 3111 to achieve a transmission connection. In this embodiment, the second pressing wheel 333 is driven by the drive shaft 311 to rotate synchronously with the first pressing wheel 323. The length of the first pin 3331 is less than the length of the first sliding groove 3111, so that the first pin 3331 can move along the length direction of the first sliding groove 3111, thereby realizing that when the movable wheel assembly 33 changes position, it does not affect the second pressing wheel 333 to rotate synchronously with the first pressing wheel 323.

[0072] The second upper pressure roller 332 is sleeved on one end of the connecting shaft 326 where the second sliding groove 3261 is provided, and a second pin key 3321 is provided on it to be inserted into the second sliding groove 3261 to achieve a transmission connection; in this embodiment, the length of the second pin key 3321 is less than the length of the second sliding groove 3261, so that the second pin key 3321 can move along the length direction of the second sliding groove 3261, thereby realizing that when the movable wheel group 33 changes position, it does not affect the second upper pressure roller 332 to rotate synchronously with the second lower pressure roller 333; the second upper pressure roller 332 is driven by the connecting shaft 326, and the pressure between it and the second lower pressure roller 333, as well as the friction between it and the rolled material, causes it to rotate synchronously with the second lower pressure roller 333.

[0073] A locking element 3311 is provided at the lower end of the movable frame 331. The locking element 3311 is used to lock and fix the position of the movable wheel assembly 33. In this embodiment, the locking element 3311 is a locking bolt. The locking bolt is threaded to the lower end of the movable frame 331. By tightening the locking bolt, its end abuts against the machine body 1, thereby achieving the locking and positioning of the movable wheel assembly 33.

[0074] Please see Figure 3 As shown, in this embodiment, a scale 11 is provided at one end of the material guiding mechanism 2 of the machine body 1, and the scale 11 is set along the width of the machine body 1; a pointer 3312 is provided at the lower end of the movable frame 331, and the pointer 3312 points to the scale and value on the scale 11. By cooperating with the scale 11, the worker can intuitively see the adjustment distance of the movable wheel set 33 and the distance between the fixed wheel set 32 ​​and the movable wheel set 33, thereby improving the adjustment efficiency and accuracy.

[0075] Please see Figure 1 and Figure 5As shown, the adjustment assembly 34 includes several first lead screw nuts 341, adjusting lead screws 342, adjusting shafts 343, transmission gear sets 344, and an adjusting handwheel 345. The several first lead screw nuts 341 are respectively fixedly connected to the bottom of the movable frame 331 and respectively threaded onto the several adjusting lead screws 342. The several adjusting lead screws 342 are rotatably mounted on the machine body 1 and are parallel to each other. One end of each adjusting lead screw 342 is connected to an adjusting shaft 343 through a transmission gear set 344. The several adjusting shafts 343 are connected through the several transmission gear sets 344 and finally connected to the adjusting handwheel 345. The adjusting handwheel 345 is mounted on the machine body 1 through a gear seat 346. In this embodiment, the number of first lead screw nuts 341 is equal to the number of adjusting lead screws 342 and the number of transmission gear sets 344. The number of adjusting shafts 343 is one less than the number of transmission gear sets 344. The transmission gear set 344 includes a first bevel gear 3441 and a second bevel gear 3442. One end of each adjusting shaft 343 is fixedly connected to a first bevel gear 3441, and the other end is fixedly connected to the first bevel gear 3441 of the next adjusting shaft 343. The first first bevel gear 3441 near the material guide mechanism 2 is fixedly connected to the adjusting handwheel 345. One end of each adjusting lead screw 342 is fixedly connected to the second bevel gear 3442. The first bevel gear 3441 and the second bevel gear 3442 are meshed and connected, and are rotatably mounted in the gear seat 346 through bearings. The gear seat 346 is mounted on the machine body 1 at intervals equal to the length of the adjusting shaft 343.

[0076] Please see Figure 1 and Figure 3 As shown, a number of second sliders 3313 are fixedly installed at the bottom of the movable frame 331, and a number of second slide rails 12 are installed on the body 1. The second slide rails 12 are parallel to the adjusting screw 342, and the second sliders 3313 are slidably connected to the second slide rails 12 respectively. By setting the second slide rails 12 and the second sliders 3313 to coordinately adjust the screw 342 and the first screw nut 341, the movable frame 331 can slide closer to or away from the fixed frame 321, thereby improving the sliding stability of the movable wheel assembly 33.

[0077] Please see Figure 1 and Figure 6 , Figure 7As shown, the material guiding mechanism 2 includes a material guiding platform 21, two limiting blocks 22 and several first adjusting screws 23. The material guiding platform 21 is fixedly installed on the machine body 1. The two limiting blocks 22 are slidably installed on the top surface of the material guiding platform 21 and can move closer or further away from each other along the width direction of the material guiding platform 21. The first adjusting screws 23 are threadedly connected to the material guiding platform 21 and are used to adjust the position of the limiting blocks 22 on the material guiding platform 21. In this embodiment, the guide platform 21 includes a left platform 211 and a right platform 212, which are separately arranged. The left platform 211 is fixedly connected to the end of the fixed frame 321 by welding or screws, and the right platform 212 is fixedly connected to the end of the movable frame 331 by welding or screws. The sum of the widths of the left platform 211 and the right platform 212 is less than the minimum distance between the fixed wheel set 32 ​​and the movable wheel set 33. The left platform 211 and the right platform 212 are located on the same horizontal plane and are flush with the highest circumferential surfaces of the first pressure roller 323 and the second pressure roller 333, so that the rolling... The material enters the roll forming mechanism 3 more stably and smoothly from the material guiding mechanism 2; the left platen 211 and the right platen 212 are respectively symmetrically provided with guide holes 213 facing left and right; the bottom of the limiting block 22 is provided with a guide bolt 221, one end of the guide bolt 221 is inserted into the guide hole 213 and can move along the length direction of the guide hole 213; each limiting block 22 is equipped with two first adjusting screws 23, and the two first adjusting screws 23 are respectively arranged parallel at both ends of the length direction of the limiting block 22 so that the two limiting blocks 22 always remain parallel when adjusting the position. By setting the guide platform 21 as a left platform 211 and a right platform 212 that are separate from the left, the width of the guide platform 21 changes as the movable wheel set 33 moves, thus performing initial width adjustment; by setting the first adjusting screw 23 to adjust the width of the limiting block 22, the width is further adjusted to adapt to the width of the rolled material, thereby improving the stability and accuracy of the guide limit; the setting of the guide hole 213 and the guide bolt 221 improves the stability of the movement of the limiting block 22.

[0078] Please see Figure 1 and Figure 7As shown, the material guiding mechanism 2 also includes a first guide roller 24 and a second guide roller 25. The first guide roller 24 and the second guide roller 25 are arranged parallel to each other at the end of the guide platform 21 away from the roll forming mechanism 3, and a guiding gap is formed between the first guide roller 24 and the second guide roller 25 for the rolled material to pass through. In this embodiment, the two ends of the first guide roller 24 respectively move through the sides of the left platform 211 and the right platform 212, and are both limited by nuts. The second guide roller 25 adopts the same installation method, so that the first guide roller 24 and the second guide roller 25 will not interfere with the width adjustment of the guide platform 21, nor will they affect their own rotation relative to the guide platform 21. The rolled material first passes through the guide gap between the first guide roller 24 and the second guide roller 25, then reaches the guide table 21 and is limited by the limiting block 22, and then enters the rolling forming mechanism 3. The first guide roller 24 and the second guide roller 25 can flatten the originally curled rolled material, thereby preventing the rolled material from arching or tilting on the guide table 21, which would affect the smooth entry of the rolled material into the rolling forming mechanism 3.

[0079] Please see Figure 6 As shown, the cutting mechanism 4 includes a movable base 41, a movable component 42, and a cutting component 43. The movable base 41 is movably mounted on the machine body 1 via the movable component 42. The movable component 42 drives the movable base 41 to move along the length of the machine body 1. The cutting component 43 is mounted on the movable base 41 and is used to cut the rolled product. The movable component 42 drives the movable base 41 to move the cutting component 43, thereby achieving product tracking and cutting without stopping the machine. This improves production efficiency and reduces the adverse effects of frequent start-up and shutdown.

[0080] Please see Figure 6 As shown, the movable seat 41 includes a base plate 411, a lifting plate 412, and a bracket 413. The base plate 411 is fixedly connected to the movable component 42. The lifting plate 412 is movably connected to the base plate 411 through a second adjusting screw 414. The bracket 413 is fixedly installed on the lifting plate 412 and is used to install the cutting component 43. In this embodiment, the base plate 411 and the lifting plate 412 are movably connected by four second adjusting screws 414, which are located at the four corners of the base plate 411. The bracket 413 is fixedly connected to the lifting plate 412 by bolts. The cutting hydraulic cylinder 431 is fixedly installed on the top of the bracket 413 by bolts. The limiting fixture 433 is detachably installed on the lifting plate 412 by bolts. Since the limiting fixture 433 can be selected and replaced according to the actual products produced, and different limiting fixtures 433 need to be re-aligned with the height of the roll forming mechanism 3, the setting of the second adjusting screws 414 and the lifting plate 412 is beneficial to adjust the height of the product hole of the limiting fixture 433 to be level with the highest wheel circumference of the first pressing roller 323, so that the product can smoothly enter the product hole of the limiting fixture 433.

[0081] Please see Figure 6 As shown, the moving component 42 includes a drive motor 421, a drive screw 422, a second screw nut 423, a first slider 424, and a first slide rail 425. The drive motor 421 is fixedly mounted on the machine body 1 and drives the drive screw 422. The drive screw 422 is rotatably mounted on the machine body 1. The second screw nut 423 is threaded onto the drive screw 422 and fixedly connected to the bottom of the base plate 411. The first slider 424 is fixedly connected to the bottom of the base plate 411 and slidably connected to the first slide rail 425. The first slide rail 425 is fixedly mounted on the machine body 1 and parallel to the drive screw 422. In this embodiment, the second lead screw nut 423 is fixed to the bottom center of the base plate 411. There are two first sliders 424, which are symmetrically arranged on both sides of the base plate 411 with the second lead screw nut 423 as the axis. There are also two first slide rails 425, which are arranged parallel to each other along the length of the machine body 1. The arrangement of the first sliders 424 and the second slide rails 12 can improve the stability when the drive screw 422 drives the second lead screw nut 423 to move the base plate 411. The drive motor 421 is located at the end of the drive screw 422 away from the roll forming mechanism 3 and is connected to the control box 6. The drive motor 421 drives the drive screw 422 to rotate. When the drive screw 422 rotates, the second lead screw nut 423 moves along its axial direction, thereby driving the base plate 411 and the entire moving seat 41 to move, and then moving the cutting assembly 43 to the preset length position to cut the formed product.

[0082] Please see Figure 6 As shown, the cutting assembly 43 includes a cutting hydraulic cylinder 431, a cutting blade 432, and a limiting fixture 433. The cutting hydraulic cylinder 431 is fixedly installed on the top of the bracket 413 and drives the cutting blade 432. The cutting blade 432 is located directly above the limiting fixture 433. The limiting fixture 433 is fixedly installed on the lifting plate 412 and is used to limit the product to be cut. In this embodiment, the cutting hydraulic cylinder 431 is hydraulically connected to the hydraulic station and electrically connected to the electrical control box 6. The limiting fixture 433 can be selected according to the actual beam product being processed. To prevent the product from bending due to the downward force applied by the cutting blade 432 when cutting the product, the limiting fixture 433 is provided with a product hole and a cutting blade hole. The product hole is provided through the limiting fixture 433 along the direction of product rolling and conveying, and its cross-sectional shape is adapted to the cross-sectional shape of the product. The cutting blade hole is provided from top to bottom and is connected to the product hole, and is perpendicular to the middle of the length direction of the product hole. The cutting hydraulic cylinder 431 drives the cutting blade 432 downward into the cutting hole, cutting the product through the product hole of the limiting fixture 433. During this process, the bottom wall of the product hole supports and limits the product on both sides of the cut, thereby effectively preventing the product from bending and deforming due to the stress of the cutting blade 432.

[0083] In summary, this utility model forms a complete profile processing flow through the material guiding mechanism 2, the roll forming mechanism 3, the cutting mechanism 4, and the material support table 5 arranged sequentially on the machine body 1. The roll forming mechanism 3 is the core for achieving width adjustment. Its fixed wheel set 32 ​​and movable wheel set 33 work together to roll and form the profile. The adjustment component 34 can drive the movable wheel set 33 to move closer to or away from the fixed wheel set 32, thereby changing the width between the two to adapt to the processing of profiles of different widths. The material guiding mechanism 2 guides and limits the profile before it enters the roll forming mechanism 3 to ensure the stability of the processing. The cutting mechanism 4 cuts the formed profile to a preset length. The material support table 5 supports the cut product.

[0084] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
