Abstract
Description
Technical Field
[0001] This application relates to the field of roll forming, and in particular to an adjustable high-strength steel roll forming apparatus. Background Technology
[0002] Currently, roll forming (also known as roll forming) is a plastic forming process that involves bending metal sheets laterally through multiple passes. Its basic principle is to feed the metal strip into a roll forming mill containing multiple pairs of rollers, with each pair of rollers gradually bending the sheet into the desired final shape.
[0003] In the prior art, a roller pressing device includes multiple sets of roller pressing seats, a roller pressing main shaft rotatably connected to the roller pressing seats, lifting blocks vertically connected to the roller pressing seats, and a roller pressing forming shaft rotatably connected to the lifting blocks. The roller pressing forming shaft cooperates with the roller pressing main shaft to press profiles. By sequentially adjusting the height of the lifting blocks on multiple roller pressing seats, multiple gradual bending can be achieved. During use, a motor drives the roller pressing main shaft to rotate, thereby pressing the profiles.
[0004] Regarding the aforementioned existing technology, by adjusting the height of the lifting block, the overall forming of cross-sections of different shapes can be ensured. In order to prevent the two ends of the roll-formed profile from becoming uneven, the forming of the groove can be controlled by adjusting the parameters of the lifting block. However, only controlling the height of the lifting block can control the thickness of the roll, and the dimensional control in other directions is poor. There are still areas for improvement in the control of roll-formed profiles. Summary of the Invention
[0005] In order to reduce the occurrence of unevenness in the profile rolling process, ensure the accuracy of profile rolling, and improve the profile processing effect, this application provides an adjustable high-strength steel rolling forming device.
[0006] The adjustable high-strength steel roll forming device provided in this application adopts the following technical solution: The device includes a base and multiple sets of roller presses on the base for pressing profiles. Each roller press includes a support base mounted on the base, a bottom rotating shaft rotatably connected to the support base near its bottom, and a lower flat roller mounted on the bottom rotating shaft. A top rotating shaft is vertically connected to the support base near its top, and an upper flat roller corresponding to the lower flat roller is mounted on the top rotating shaft. A first adjusting device for adjusting the height of the top rotating shaft is provided on the support base. An auxiliary slide is provided between the top rotating shaft and the bottom rotating shaft. The auxiliary slide includes two auxiliary seats located on both sides of the lower flat roller, and side flat rollers rotatably connected to the auxiliary seats. A second adjusting device for adjusting the distance between the auxiliary seats and the lower flat roller is provided on the support base. The two side flat rollers, the upper flat roller, and the lower flat roller together form a molding cavity for pressing the profile.
[0007] By adopting the above technical solution, during processing, the motor drives the rotating shaft to rotate. The positions of the upper flat roller and the side flat roller can be adjusted through the first and second adjusting devices, and gradually decreased according to the sorting direction of the roller pressing seats, thereby achieving the purpose of gradually pressing the profile. If the pressed size of the profile is too large, the distance between the first and second adjusting devices is reduced, and the upper flat roller and the side flat roller locally squeeze to achieve shaping and pressure retention, offsetting the dimensional deviation caused by stress release. If the size is too small, the distance is increased by adjusting in the opposite direction until the cross-sectional size is consistent. By adjusting the pressing size in multiple directions, the occurrence of large and small ends during the profile rolling process is reduced, ensuring the accuracy of profile rolling and improving the profile processing effect.
[0008] Preferably, the support base consists of two support columns fixed to the base plate. The first adjustment device includes a lifting slider slidably connected to the support column, and the rotating bottom shaft is rotatably connected to the lifting slider. A first adjusting stud is threadedly connected to the support column, and the bottom of the first adjusting stud is rotatably connected to the lifting slider. The second adjustment device includes a plurality of second adjusting studs threadedly connected to the auxiliary base, and the side of the first adjusting stud away from the auxiliary base abuts against the support column.
[0009] By adopting the above technical solution, the first adjusting stud and the second adjusting stud can be used to adjust the position of the upper flat roller and the side flat roller, thereby improving the convenience of pressing the profile.
[0010] Preferably, the support column has horizontal plates on both sides, the support column has multiple positioning holes on its sidewalls, the horizontal plates have adjustment waist holes near both sides, positioning bolts are inserted into the adjustment waist holes, the positioning bolts are threadedly connected to the positioning holes, the auxiliary seat has locking waist holes on both sides, and locking bolts are inserted into the locking waist holes and threadedly connected to the horizontal plates.
[0011] By adopting the above technical solution, the installation of the horizontal plate can make the auxiliary seat more secure and improve the stability of the side roller fixing.
[0012] Preferably, a guide ring is rotatably connected between two adjacent roller pressing seats. The guide ring has a guide cavity formed inside for inserting the profile. A sliding arc groove is provided on the base to slide and cooperate with the support column. The sliding arc groove is coaxially arranged with the guide ring. Multiple support cylinders are rotatably connected to the base. The end of the support cylinder away from the base is rotatably connected to the support column.
[0013] By adopting the above technical solution, the rotation of the support column can be controlled by the support cylinder during use, thereby allowing the molding cavity to rotate, thus achieving the purpose of rotating the profile and improving the convenience of processing profiles with different rotation angles.
[0014] Preferably, the bottom of the support column is provided with a guide slider, and the bottom of the sliding arc groove is provided with a guide groove that slides and cooperates with the guide slider.
[0015] By adopting the above technical solution, the guide slider and guide groove cooperate to enable the support column to rotate more smoothly and restrict the rotation of the support column, thereby improving the stability of the support column in use.
[0016] Preferably, the guide slider is threadedly connected to a fixing bolt, which abuts against the bottom of the guide groove.
[0017] By adopting the above technical solution, the guide slider can be locked more securely by fixing bolts, thereby improving the stability of the support column.
[0018] Preferably, the base plate is composed of multiple hinged plates that are hinged to each other, and multiple support seats are arranged in one-to-one correspondence with multiple hinged plates. The side wall of each hinged plate is provided with a rotary cylinder for driving two adjacent hinged plates to rotate.
[0019] By adopting the above technical solution, the two adjacent hinge plates can be rotated and connected by rotating the cylinder, thereby enabling the two adjacent support seats to generate a corner, thus processing profiles with corners and improving the convenience of processing profiles.
[0020] Preferably, a connecting locking plate is provided between two adjacent hinge plates, and connecting bolts are inserted into both ends of the connecting locking plate, with the connecting bolts threadedly connected to the hinge plates.
[0021] By adopting the above technical solution, the two hinge plates can be locked during use by connecting the locking plate, thereby improving the stability of the hinge plate locking.
[0022] Preferably, the guide ring is composed of two guide short rings that are hinged together, and the rotation direction of the guide short rings is consistent with the rotation direction of the hinge plate.
[0023] By adopting the above technical solution, the guide short ring can better connect the two support seats during use, thereby improving the firmness of the connection between the two adjacent support seats.
[0024] Preferably, the inner wall of the guide ring is provided with a guide seat, and the guide seat has a guide arc surface on the side near the profile.
[0025] By adopting the above technical solution, when processing curved profiles, rotating the guide short ring can simultaneously drive the guide seat to rotate. During the processing, as the profile passes through the guide arc surface, the guide seat can guide the profile, thereby enabling the profile to be processed more smoothly.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. During processing, the motor drives the rotating base shaft to rotate. The positions of the upper flat roller and the side flat roller can be adjusted through the first and second adjusting devices, and gradually reduced according to the arrangement direction of the roller pressing seats, thereby achieving the purpose of progressively pressing the profile. If the pressed size of the profile is too large, the distance between the first and second adjusting devices is reduced, and the upper flat roller and the side flat roller locally squeeze to achieve shaping and pressure retention, offsetting the dimensional deviation caused by stress release. If the size is too small, the distance is increased in the opposite direction until the cross-sectional dimensions are consistent. By adjusting the pressing size in multiple directions, the occurrence of large and small ends during the profile rolling process is reduced, ensuring the accuracy of profile rolling and improving the profile processing effect. 2. During use, the rotation of the support column can be controlled by the support cylinder, which in turn allows the molding cavity to rotate, thereby achieving the purpose of rotating the profile and improving the convenience of processing profiles with different rotation angles; 3. By rotating the cylinder, two adjacent hinge plates can be rotated and connected, thereby allowing two adjacent support seats to rotate, thus producing profiles with corners and improving the convenience of profile processing.

[0029] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.
[0030] This application discloses an adjustable high-strength steel roll forming device.
[0031] Example 1 Reference Figure 1 An adjustable high-strength steel roll forming device includes a base 1 and multiple sets of roll forming seats on the base 1 for pressing profiles 4. Each roll forming seat includes a support seat 5 bolted to the base 1. A rotating bottom shaft 2 is rotatably connected to the support seat 5 near its bottom, and a lower flat roller 8 is mounted on the rotating bottom shaft 2. A rotating top shaft 3 is vertically connected to the support seat 5 near its top, and an upper flat roller 6 corresponding to the lower flat roller 8 is mounted on the rotating top shaft 3. A first adjustment device for adjusting the height of the rotating top shaft 3 is mounted on the support seat 5. An auxiliary sliding assembly is installed between the rotating top shaft 3 and the rotating bottom shaft 2. The auxiliary sliding assembly includes two auxiliary seats 13 symmetrically installed on both sides of the lower flat roller 8. Side flat rollers 12 are rotatably connected to the auxiliary seats 13. A second adjustment device for adjusting the distance between the auxiliary seats 13 and the lower flat roller 8 is mounted on the support seat 5. The two side flat rollers 12, the upper flat roller 6, and the lower flat roller 8 together form a molding cavity 7 for pressing the profile 4. The molding cavity 7 is B-shaped, allowing for more stable processing through pressure in four directions. The forming parameters of the upper flat roller 6 and the lower flat roller 8 are preset, and the initial spacing is set through the first and second adjustment devices. Finally, the lateral spacing of the auxiliary seat 13 is finely adjusted according to the real-time detected dimensions of the profile 4, so as to accurately correct the large and small end errors. This not only ensures the integrity of the B-shaped cross-section, but also adapts to the batch material fluctuations of ultra-high strength steel, effectively controlling the large and small end errors of the profile 4 within a high-precision range, significantly reducing the scrap rate, and providing reliable technical support for the precision roll forming of ultra-high strength steel profiles 4.
[0032] The support base 5 consists of two support columns 51 fixed to the base 1. The first adjustment device includes a lifting slider 18 slidably connected to the support column 51, a rotating base shaft 2 rotatably connected to the lifting slider 18, and a first adjusting stud 17 threadedly connected to the support column 51. The bottom of the first adjusting stud 17 is rotatably connected to the lifting slider 18. The second adjustment device includes multiple second adjusting studs 11 threadedly connected to the auxiliary base 13. The side of the second adjusting stud 11 away from the auxiliary base 13 abuts against the support column 51, improving the convenience of pressing the profile 4.
[0033] A rectangular plate 9 is installed on both sides of the support column 51. Multiple positioning holes are provided on the side wall of the support column 51. Adjustment holes 14 are provided near the sides of the horizontal plate 9, and positioning bolts 15 are inserted into the adjustment holes 14. The positioning bolts 15 are threadedly connected to the positioning holes. Locking holes 26 are provided on both sides of the auxiliary seat 13, and locking bolts 10 are threadedly connected to the horizontal plate 9 in the locking holes 26, thereby more stably fixing the auxiliary seat 13. A support screw 16 is threadedly connected to the bottom of the horizontal plate 9, and the bottom of the support screw 16 abuts against the base 1.
[0034] The implementation principle of the adjustable high-strength steel roll forming device in this application embodiment is as follows: During processing, the positions of the upper flat roller 6 and the side flat roller 12 can be adjusted by the first adjusting stud 17 and the second adjusting stud 11, and gradually reduced according to the sorting direction of the roll forming seats, thereby achieving the purpose of gradually pressing the profile 4; if the pressed size of the profile 4 is too large, the distance between the upper flat roller 6 and the side flat roller 12 is reduced, and the upper flat roller 6 and the side flat roller 12 are locally squeezed to achieve shaping and pressure retention, thereby offsetting the dimensional deviation caused by stress release; if the size is too small, the distance is increased in the opposite direction until the cross-sectional size is consistent. By adjusting the pressing size in multiple directions, the occurrence of large and small ends during the roll forming process of the profile 4 is reduced, ensuring the accuracy of the roll forming of the profile 4 and improving the processing effect of the profile 4.
[0035] Example 2 Reference Figure 5 The difference between this embodiment and Embodiment 1 is that a guide ring 19 is rotatably connected between two adjacent roller pressing seats. The guide ring 19 has a guide cavity formed inside for inserting the profile 4. A sliding groove is provided on the base 1 to slide and engage with the support column 51. The sliding groove is coaxially arranged with the guide ring 19, allowing the support column 51 to rotate more smoothly. Multiple connecting rods 21 are provided on the support seat 5. The connecting rods 21 are cross-shaped, and the end of the connecting rod 21 away from the support seat 5 is rotatably connected to the guide ring 19. Multiple support cylinders 25 are rotatably connected to the base 1. One end of the support cylinder 25 is rotatably connected to the support column 51, allowing the molding cavity 7 to rotate, thereby achieving the purpose of rotating the profile 4 and improving the convenience of processing profiles 4 at different rotation angles.
[0036] A guide slider 22 is installed at the bottom of the support column 51, and a guide groove 24 is provided at the bottom of the sliding groove to slide and cooperate with the guide slider 22. A fixing bolt is threaded onto the guide slider 22, and the fixing bolt abuts against the bottom of the guide groove 24, which can make the support column 51 more stable.
[0037] The base plate consists of multiple hinge plates 101 that are hinged together. Multiple support seats 5 are arranged one-to-one with the multiple hinge plates 101. A rotary cylinder 20 for driving the rotation of two adjacent hinge plates 101 is fixed to the side wall of each hinge plate 101. A connecting locking plate 28 is fixed between two adjacent hinge plates 101. Connecting bolts are inserted into both ends of the connecting locking plate 28, and the connecting bolts are threadedly connected to the hinge plates 101.
[0038] The guide ring 19 consists of two hinged guide short rings 191, whose rotation direction is the same as that of the hinge plate 101. This improves the firmness of the connection between two adjacent support seats 5. A guide seat 27 is provided on the inner wall of the guide short ring 191. The guide seat 27 has a guiding arc surface on the side near the profile 4, which guides the profile 4, allowing for smoother processing.
[0039] The implementation principle of Example 2 is as follows: When in use, by rotating the support column 51 and rotating the hinge plate 101, the purpose of twisting and turning the profile 4 can be achieved, thereby improving the convenience and effect of rolling the profile 4.
[0040] 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.
