For example, the first driving member can be a driving motor and the second driving mechanism can be a lifting cylinder. Specifically, the first reducer 1311 and the second reducer 1321 adjust and output the rotational speed, respectively driving the axial displacement of the first movable screw sleeve 1312 and the second movable screw sleeve 1322, and then driving the adjustment of the relative displacement of the inner movable sleeve 171 and the outer movable sleeve 181, thereby realizing the axial spacing adjustment between the two vertical roller sleeves 123 in the same steel channel and the movement adjustment of the flat roller sleeve 121. In particular, when the same group of flat roller assemblies has two flat roller sleeves 121, the effective width of the flat roller assembly can be adjusted by adjusting the gap width between the two flat roller sleeves 121, thereby adjusting the width of the forming channel 124 in the axial direction of the transmission shaft 11.

[0071] Optionally, the number of molding units 12 is two, and the two molding units 12 are distributed at intervals along the axial direction of the transmission shaft 11. Two groups of external movable transmission modules 132 and two groups of internal movable transmission modules 131 are symmetrically installed on each transmission shaft 11. The two groups of external movable transmission modules 132 correspond to the two molding units 12 respectively, and the two groups of internal movable transmission modules 131 correspond to the two molding units 12 respectively. That is to say, each molding unit 12 is provided with two groups of external movable transmission modules 132 and two groups of internal movable transmission modules 131. The two groups of external movable transmission modules 132 are respectively arranged on the two transmission shafts 11, and the two groups of internal movable transmission modules 131 are respectively arranged on the two transmission shafts 11.

[0072] Optionally, the lifting and adjusting mechanism 16 includes an oil cylinder, a hydraulic cylinder or a sliding locking structure; when the lifting and adjusting mechanism 16 is an oil cylinder, the oil cylinder is installed on the corresponding first bearing seat 172 or the second bearing seat 182, and the output end of the oil cylinder is connected to the corresponding vertical roller shaft 122. The oil cylinder can stop running at any time according to demand and remain in a locked state to lock in a specified position, so that the vertical roller assembly is locked in a specified position to flexibly realize the lifting and lowering adjustment of the vertical roller sleeve 123, the adjustment is simple and convenient, and the structure of the vertical roller assembly is simplified. Furthermore, the end of the vertical roller shaft 122 not connected to the lifting and adjusting mechanism 16 can be slidably connected to the corresponding first bearing seat 172 or second bearing seat 182, and locked by a locking pin when the vertical roller shaft 122 is raised or lowered to a specified position. Specifically, the first bearing seat 172 and the second bearing seat 182 are each provided with a slide groove, and the first bearing seat 172, the second bearing seat 182, and the vertical roller shaft 122 are each provided with corresponding locking holes. The vertical roller shaft 122 slides within the slide groove, and the locking pin engages with different locking holes to achieve axial movement and adjustment of the vertical roller shaft 122. In this embodiment, the lower end of each vertical roller shaft 122 is connected to the corresponding bearing seat via the lifting and adjusting mechanism 16, and the upper end of the vertical roller shaft 122 is connected to the corresponding bearing seat via a locking pin.

[0073] It is understood that the connection between the vertical roller shaft 122 and the corresponding bearing seat is not limited to connection via the lifting and adjusting mechanism 16, and a fixed connection can also be used. In addition, the number and shape of the flat roller sleeves 121 in each flat roller assembly can be flexibly combined according to the shape and size of the workpiece 4. The number and shape of the vertical roller sleeves 123 in each vertical roller assembly can also be flexibly combined according to the shape and size of the workpiece 4, and are not limited to the above-mentioned examples. The workpiece 4 can be structural steel.

The flat roller sleeve 121 and the vertical roller sleeve 123 are more convenient and flexible to adjust, and the size of the forming channel 124 can be flexibly adjusted according to needs.

The size of the forming channel 124 can be flexibly adjusted according to demand, which facilitates automation.

[0084] Embodiment 5:

[0085] 1 and 10 , the difference between this embodiment and the first embodiment is that, in each molding unit 12, the upper end of the vertical roller shaft 122 of the one group of vertical roller assemblies away from the adjacent molding unit 12 of the two groups of vertical roller assemblies is connected to the corresponding bearing seat through a lifting adjustment mechanism 16, and the lower end of the vertical roller shaft 122 is connected to the corresponding bearing seat through a locking pin, and the upper end of the vertical roller shaft of the other group of vertical roller assemblies is connected to the corresponding bearing seat through a locking pin, and the lower end of the vertical roller shaft 122 is connected to the corresponding bearing seat through a lifting adjustment mechanism 16. That is to say, the two groups of vertical roller assemblies in each molding unit 12 adopt up and down cross sliding adjustment, that is, the upper end of one group of vertical roller assemblies is connected to the corresponding bearing seat through the lifting adjustment mechanism 16, and the lower end of the other group of vertical roller assemblies is connected to the corresponding bearing seat through the lifting adjustment mechanism 16.

[0086] In the roll forming device 1 of the above embodiment, the vertical roller assembly can be independently adjusted for lifting and lowering, and the flat roller sleeve 121 and the vertical roller sleeve 123 are more convenient and flexible to adjust. The size of the forming channel 124 can be flexibly adjusted according to demand, which facilitates automation.

[0087] Example 6:

[0088] Referring to Figures 1 and 11 , this embodiment differs from the first embodiment in that the lower end of each vertical roller shaft 122 is connected to the corresponding bearing seat via a lifting and adjusting mechanism 16 , and the upper end of each vertical roller shaft 122 is slidably connected to the corresponding bearing seat. Specifically, a slide groove is provided on each bearing seat corresponding to each vertical roller shaft 122 , and the upper end of the vertical roller shaft 122 extends into and is able to slide within the slide groove. The sliding engagement between the upper end of the vertical roller shaft 122 and the corresponding bearing seat provides movement space for the lifting and adjusting mechanism 16 to drive the vertical roller shaft 122 to rise and fall.

[0089] In the roll forming device 1 of the above embodiment, the same end of each vertical roller 122 can be synchronously raised and lowered to adapt to the steel forming processing of open or closed structures of different shapes.

[0090] Embodiment seven:

[0091] Referring to Figures 1 and 12, the difference between this embodiment and the fifth embodiment is that the flat roller sleeves 121 of the two sets of flat roller assemblies and the vertical roller sleeves 123 of the two sets of vertical roller assemblies are adjacent to each other end to end to form a forming channel 124, the flat roller sleeves 121 of the two sets of flat roller assemblies are respectively an upper flat roller sleeve and a lower flat roller sleeve, the vertical roller sleeve 123 of the first vertical roller assembly is a first vertical roller sleeve, and the vertical roller sleeve 123 of the second vertical roller assembly is a second vertical roller sleeve, the head end of the upper flat roller sleeve and the tail end of the second vertical roller sleeve partially overlap in the axial direction of the upper flat roller sleeve, and the overlapping length and width can be X11, and the upper flat roller sleeve is located above the second vertical roller sleeve, and the second vertical roller sleeve is located above the second vertical roller sleeve. The leading end of the roller sleeve partially overlaps with the trailing end of the lower flat roller sleeve in the axial direction of the second vertical roller sleeve, and the overlapping width may be Y11. The second vertical roller sleeve is located on the side of the lower flat roller sleeve close to the adjacent forming unit 12. The leading end of the lower flat roller sleeve partially overlaps with the trailing end of the first vertical roller sleeve in the axial direction of the lower flat roller sleeve, and the overlapping width may be X12. The lower flat roller sleeve is located below the first vertical roller sleeve. The leading end of the first vertical roller sleeve partially overlaps with the trailing end of the upper flat roller sleeve in the axial direction of the first vertical roller sleeve, and the overlapping width may be Y12. The first vertical roller sleeve is located on the side of the upper flat roller sleeve away from the adjacent forming unit 12. In this embodiment, the leading end of the upper flat roller sleeve refers to the end close to the adjacent forming unit 12, the leading end of the lower flat roller sleeve refers to the end away from the adjacent forming unit 12, the first vertical roller sleeve refers to the vertical roller sleeve 123 away from the adjacent forming unit 12, and the second vertical roller sleeve refers to the vertical roller sleeve 123 close to the adjacent forming unit 12, that is, the two forming units 12 are arranged symmetrically.

[0092] Optionally, each flat roller assembly includes only one flat roller sleeve 121, and each vertical roller assembly includes only one vertical roller sleeve 123. Alternatively, each flat roller assembly includes two flat roller sleeves 121 distributed axially along the drive shaft 11, and the gap between the two flat roller sleeves 121 in the axial direction of the drive shaft 11 is adjustable, and the gap can be greater than or equal to 0 mm. In this embodiment, each flat roller assembly includes only one flat roller sleeve 121, wherein one of the two flat roller sleeves 121 in the same forming unit 12 can move axially along the drive shaft 11 synchronously with the outer sleeve unit 18, and the other flat roller sleeve 121 can move axially along the drive shaft 11 synchronously with the inner sleeve unit 17. In other words, one of the two flat roller sleeves 121 and one of the two vertical roller sleeves 123 can move synchronously with the same outer sleeve unit 18, and the other flat roller sleeve 121 and the other vertical roller sleeve 123 can move synchronously with the same inner sleeve unit 17. Furthermore, the flat roller sleeves 121 and vertical roller shaft 122 are connected to one end of the lifting and adjusting mechanism 16 and can move together along the axial direction of the drive shaft 11. This allows for the formation of steel for open or closed structures of varying shapes and controls the deformation of the forming channel, improving the quality of the formed product. Specifically, the spacing between the two flat roller sleeves 121 is Y1, and the spacing between the two vertical roller sleeves 123 is X1. When the first drive member, the second drive mechanism, and the lifting and adjusting mechanism 16 operate, the vertical roller sleeves 123 and the flat roller sleeves 121 move toward the center of the forming channel 124, reducing the dimensions of the forming channel 124, thereby reducing X1 and Y1.

[0093] The roll-bending forming device 1 of the above embodiment, in addition to having the advantages of the roll-bending forming device 1 of the fifth embodiment, is capable of forming a closed forming channel 124 by cooperating with the vertical roller sleeve 123 and the flat roller sleeve 121, thereby increasing the contact area between the vertical roller sleeve 121 and the workpiece 4. In particular, when the workpiece 4 is large in size, the closed forming channel 124 can ensure the forming quality of the workpiece 4. In addition, the size of the forming channel 124 can always remain closed as the size specifications become smaller, and the application is flexible and the adaptability is wide.

[0094] Embodiment 8:

The distance between the two flat roller sleeves 121 is Y2, and the distance between the two vertical roller sleeves 123 is X2. When the first driving member, the second driving mechanism, and the lifting and adjusting mechanism 16 operate, the vertical roller sleeves 123 and the flat roller sleeves 121 are driven away from the center of the forming channel 124, so that the size specifications of the forming channel 124 become larger, that is, X2 and Y2 become larger.

[0096] In the roll bending forming device 1 of the above embodiment, the vertical roller sleeve 123 and the flat roller sleeve 121 can cooperate to form a closed forming channel 124, thereby increasing the contact area between the vertical roller sleeve 123 and the flat roller sleeve 121 and the workpiece 4. Especially when the workpiece 4 is large in size, the closed forming channel 124 can ensure the forming quality of the workpiece 4; in addition, the size of the forming channel 124 can always remain closed as the size specifications increase, and it is flexible in application and has a wide range of adaptability.

[0098] The first driving mechanism 13 is started, and the operation of the first driving mechanism 13 drives the vertical roller assembly and the flat roller assembly to move to a preset position in the axial direction of the transmission shaft 11, so as to adjust the size of the forming channel 124 in the axial direction of the transmission shaft 11;

[0099] The second driving mechanism is started, and the second driving mechanism operates to drive the vertical roller assembly and the flat roller assembly to rise and fall to a preset position in the axial direction of the vertical roller assembly to adjust the size of the forming channel in the axial direction of the vertical roller assembly; or, the second driving mechanism and the lifting adjustment mechanism 16 are started, and the second driving mechanism and the lifting adjustment mechanism 16 cooperate to drive the vertical roller assembly and the flat roller assembly to move to a preset position in the axial direction of the vertical roller assembly to adjust the size of the forming channel 124 in the axial direction of the vertical roller assembly; or, the lifting adjustment mechanism 16 is started, and the lifting adjustment mechanism 16 operates to drive the vertical roller assembly to move to a preset position in the axial direction of the vertical roller assembly.

When the travel position is close to the ends of the transmission shaft 11, the push-pull devices 203 near the ends of the transmission shaft 11 can be used to drive the components to be disassembled. This layout method has lower travel requirements for the push-pull devices, which is conducive to reducing the travel requirements of the push-pull devices, reducing the space occupied in the workshop, and facilitating disassembly and assembly, thereby improving disassembly and assembly efficiency.

Furthermore, a plurality of support sliders 202 are respectively arranged corresponding to the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31, that is, the support slider 202 is supported and matched with the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31, and the jack 207 acts on the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31; the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31 can be directly placed on the support slider 202, and can move with the support slider 202 under the action of the gravity of the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31 themselves, or can be connected to the support slider 202 through a connecting piece to ensure that it is in contact with the support slider 20 2 moves together; wherein, the supporting slider 202 can cooperate with the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31 respectively, thereby driving the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31 to move respectively, and can also cooperate with the first bearing seat 172 to drive the first bearing seat 172, the second bearing seat 182 and the frame bearing seat 31 to move together; specifically, the push-pull device 203 includes two first push-pull devices 203 and two second push-pull devices 203, the two second push-pull devices 203 are located between the two first push-pull devices 203, and the second push-pull devices 203 are provided with a displacement sensor, which can timely measure the movement displacement of the supporting slider 202 driven by the second push-pull device 203.

[0107] Optionally, the shape of the portion of the support slider 202 that mates with the corresponding bearing seat matches the shape of the corresponding bearing seat. The shape of the portion of the support slider 202 that mates with the corresponding bearing seat can be flexibly set; specifically, the shape of the support slider 202 corresponding to the second bearing seat 182 matches the shape of the second bearing seat 182, the shape of the support slider 202 corresponding to the first bearing seat 173 matches the shape of the first bearing seat 173, and the shape of the support slider 202 corresponding to the frame bearing seat 31 matches the shape of the frame bearing seat 31.

[0116] Referring to Figures 1 to 4, 14 to 16, and 19 to 22, in some optional embodiments, the present application further provides a method for disassembling the roll forming device 1 as in any of the above embodiments, the disassembly method being implemented by the disassembly device 2 as in any of the above embodiments, and the disassembly method comprising:

[0117] The connection between the frame bearing unit 3, the inner sleeve unit 17 and the outer sleeve unit 18 and the corresponding transmission shaft 11 is disassembled so that the frame bearing unit 3, the inner sleeve unit 17 and the outer sleeve unit 18 can move in the axial direction of the transmission shaft 11 and slide out from the end of the transmission shaft 11, thereby being separated from the transmission shaft 11, so that the frame bearing unit 3, the inner sleeve unit 17 and the outer sleeve unit 18 can be lifted by the lifting mechanism for maintenance and replacement; specifically, the limit end caps installed on both ends of the transmission shaft 11 can be removed from the transmission shaft 11 so that the frame bearing unit 3, the inner sleeve unit 17 and the outer sleeve unit 18 can slide out from the end of the transmission shaft 11. The frame bearing unit 3, the outer sleeve unit 18 and the inner sleeve unit 17 are sequentially moved away from the end of the transmission shaft 11, and the frame bearing unit 3, the outer sleeve unit 18 and the inner sleeve unit 17 are connected together so that the frame bearing unit 3, the outer sleeve unit 18 and the inner sleeve unit 17 can move together.

[0118] The operation of the push-pull device 203 drives the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 to move together in the axial direction of the transmission shaft 11 until they are separated from the transmission shaft 11 and reach the first preset position. After reaching the first preset position, the connection between the frame bearing unit 3 and the outer sleeve unit 18 is disassembled, and the connection between the frame bearing unit 3 and the outer sleeve unit 18 is disconnected, and the frame bearing unit 3 no longer moves together with the outer sleeve unit 18, or the frame bearing unit 3 can be fixed in the first preset position and remain stationary to avoid driving the frame bearing unit 3 to move when the outer sleeve unit 18 moves; specifically, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are connected together, and the support slider 202 is supported on the bottom of the first bearing seat 172 of the inner sleeve unit 17, and the first bearing seat 172 can be directly placed on the support slider The first bearing seat 172 is fixed to the support slide 202 by a locking mechanism to prevent the first bearing seat 172 from being separated from the support slide 202 during movement. The swing hook 206 of the flip push-pull device 203 is hooked and connected with the hook 205 of the support slide 202. The operation of the push-pull device 203 drives the support slide 202 corresponding to the inner sleeve unit 17 to move the stroke A2, that is, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 move from the initial position to the first preset position. When the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 reach the first preset position, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are all separated from the transmission shaft 11. In the initial position, the distance between the frame bearing seats 31 is A1. The support slide 202 can also be supported and connected to the second bearing seat 182 or the frame bearing seat 31. During the disassembly process, the support slide 202 is supported and connected to the first bearing seat 172 near the end, which can avoid frequent operation of the swing hook 206 and improve disassembly efficiency.

[0119] The operation of the push-pull device 203 drives the outer sleeve unit 18 and the inner sleeve unit 17 to move in the axial direction of the transmission shaft 11 in the direction away from the transmission shaft 11 to reach the second preset position. After reaching the second preset position, the connection between the outer sleeve unit 18 and the inner sleeve unit 17 is disconnected. The outer sleeve unit 18 and the inner sleeve unit 17 are disconnected and no longer move together with the inner sleeve unit 17. Alternatively, the outer sleeve unit 18 can be fixed at the second preset position and remain stationary to avoid driving the outer sleeve unit 18 when the inner sleeve unit 17 moves. Element 18 moves; specifically, the outer sleeve unit 18 is connected to the inner sleeve unit 17, and the swing hook 206 of the flip push-pull device 203 is hooked and connected with the hook 205 of the support slider 202. The push-pull device 203 drives the support slider 202 corresponding to the inner sleeve unit 17 to move the stroke A3, that is, the inner sleeve unit 17 and the outer sleeve unit 18 move from the first preset position to the second preset position. When reaching the second preset position, the inner sleeve unit 17 and the outer sleeve unit 18 are completely separated from the frame bearing unit 3.

[0120] The operation of the push-pull mechanism 203 drives the inner sleeve unit 17 to move in the axial direction of the transmission shaft 11 in a direction away from the transmission shaft 11 to the third preset position, with the first preset position, the second preset position, and the third preset position being successively farther away from the end of the transmission shaft 11. Specifically, the swing hook 206 of the flip push-pull mechanism 203 is hooked and connected with the hook 205 of the support slider 202. The operation of the push-pull mechanism 203 drives the support slider 202 corresponding to the first bearing seat 172 of the inner sleeve unit 17 to move a stroke A4, that is, the inner sleeve unit 17 moves from the second preset position to the third preset position. When the inner sleeve unit 17 reaches the third preset position, it is completely separated from the outer sleeve unit 18, and the disassembly is completed. After the disassembly is completed, the corresponding vertical roller assembly and flat roller assembly can be replaced. After the vertical roller assembly and flat roller assembly are replaced, the inner sleeve unit 17, the outer sleeve unit 18, and the frame bearing seat 31 can be assembled in the reverse order of disassembly, that is, first move the inner sleeve unit 17 from the third preset position to the second preset position and connect it with the outer sleeve unit 18, and then move the inner sleeve unit 17 and the outer sleeve unit 18 from the second preset position to the first preset position together and then connect them with the frame bearing seat 31, and then move the inner sleeve unit 17, the outer sleeve unit 18 and the frame bearing seat 31 together from the first preset position to the initial position, the supporting slider 202 can always be connected to the first bearing seat 172, or it can be connected to the second bearing seat 183 when returning to the second preset position, or it can be connected to the frame bearing seat 31 when returning to the first preset position. The assembly principle is the same as the disassembly principle, and will not be repeated here.

[0121] The disassembly and assembly method of the above embodiment is simple and convenient to operate. The disassembly and assembly device 2 can quickly complete the disassembly and replacement of the vertical roller assembly, flat roller assembly, inner sleeve unit 17, outer sleeve unit 18, and frame bearing seat 31 of the roll bending forming device 1. It can not only quickly adjust the size and / or shape of the forming channel 124 to adapt to the production of workpieces 4 of different sizes and / or shapes, but also facilitate online adjustment to achieve automated production, reduce production costs, and improve production efficiency.

[0122] It can be understood that the disassembly and assembly device and disassembly and assembly method of the above embodiment can be used not only for the roll forming device of the above embodiment, but also for a roll forming device that does not have a vertical roller assembly.
