Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, and in particular to a roll forming device, adjustment method, disassembly and assembly device, and disassembly and assembly method. Background Technology

[0002] Currently, cold forming technology for structural steel uses single-channel forming, resulting in simple forming equipment that relies on manual or mechanical adjustments and cannot be adjusted online, leading to poor production quality and low efficiency. Hot bending technology for structural steel, on the other hand, utilizes residual heat after slab rolling for direct bending, making it more environmentally friendly. However, regardless of whether it's cold or hot forming, when producing structural steel of different specifications or shapes using the same bending forming device, either frequent replacement of the forming roller sleeves is required, or the forming roller sleeves can only move and adjust their position along with the drive shaft, unable to be adjusted independently. This makes adjusting the forming channel specifications inconvenient, resulting in low production efficiency and high costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a roll forming device, adjustment method, disassembly device and disassembly method to solve the problems of inconvenient adjustment of the forming channel, inability to adjust online, low efficiency and high cost of the roll forming device in the prior art.

The present invention solves the problems of limited adjustment of forming channel size and the need for frequent replacement of forming roller sleeves to achieve size adjustment and poor flexibility in the traditional forming process of structural steel.

[0063] See Figures 1 to 13 In some optional embodiments, this application provides a roll forming apparatus 1. The roll forming apparatus 1 of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. However, it should be understood that the roll forming apparatus 1 of this application is not limited to the following embodiments.

Each forming unit 12 includes two sets of flat roller assemblies and two sets of vertical roller assemblies. The two sets of flat roller assemblies are respectively mounted on the two drive shafts 11, and the two ends of each set of vertical roller assemblies are respectively connected to the two drive shafts 11. The flat roller assemblies and vertical roller assemblies form a forming channel 124, and the flat roller assemblies and vertical roller assemblies are alternately distributed along the circumference of the forming channel 124. The first drive mechanism 13 is connected to the flat roller assemblies and vertical roller assemblies to drive the flat roller assemblies and vertical roller assemblies to move along the axial direction of the drive shafts 11. The axial direction of the flat roller assemblies is parallel to that of the drive shafts 11. The axes of the two drive shafts 11 are parallel, and the axis of the vertical roller assembly is perpendicular to the axis of the drive shaft 11. The second drive mechanism is used to adjust the distance B1 between the two drive shafts 11. The second drive mechanism is connected to the drive shaft 11. The operation of the second drive mechanism drives the drive shaft 11 to move closer or further away to adjust the distance B1 between the two drive shafts 11. The distance B1 refers to the distance between the first center lines 111 of the two drive shafts 11. At least one end of the vertical roller assembly is connected to the drive shaft 11 through the lifting adjustment mechanism 16. The lifting adjustment mechanism 16 can drive the vertical roller assembly to move up and down in the axial direction of the vertical roller assembly and lock it in a specified position. The lifting adjustment mechanism 16 can move synchronously with the corresponding vertical roller assembly along the axial direction of the drive shaft 1. The first drive mechanism 13, the second drive mechanism, and the lifting adjustment mechanism 16 can drive the flat roller assembly and the vertical roller assembly to move to adjust the size of the forming channel 124.

In the two sets of vertical roller assemblies of the same forming unit, the vertical roller assembly farther away from the adjacent forming unit 12 is the first vertical roller assembly, and the other set of vertical roller assemblies is the second vertical roller assembly. That is, the vertical roller assembly closer to the adjacent forming unit 12 is the second vertical roller assembly. The two ends of the first vertical roller assembly are respectively connected to the outer bushing units 18 on the two drive shafts 11, and the two ends of the second vertical roller assembly are respectively connected to the inner bushing units 17 on the two drive shafts 11.

[0067] Optionally, the flat roller assembly includes a flat roller sleeve 121, which is connected to the outer bushing unit 18 and can move axially along the drive shaft 11 with the outer bushing unit 18; or the flat roller sleeve 121 is connected to the inner bushing unit 17 and can move axially along the drive shaft 11 with the inner bushing unit 17. The flat roller sleeve 121 and the vertical roller sleeve 123 cooperate to form a forming channel 124. Specifically, the outer side wall of the flat roller sleeve 121 and the outer side wall of the vertical roller sleeve 123 cooperate to form the forming channel 124. In each forming unit, at least one of the two sets of flat roller assemblies includes two flat roller sleeves 121 distributed axially along the drive shaft 11, and one of the two flat roller sleeves 121 is connected to the outer bushing unit 18, while the other flat roller sleeve 121 is connected to the inner bushing unit 17. In this embodiment, each flat roller assembly includes two flat roller sleeves 121. One of the flat roller sleeves 121 in the same flat roller assembly is sleeved on the drive shaft 11 and connected to the outer bushing unit 18, and can move axially along the drive shaft 11 with the outer bushing unit 18. The other flat roller sleeve 121 is connected to the inner bushing unit 17 and can move axially along the drive shaft 11 with the inner bushing unit 17.

[0068] Optionally, the inner bushing unit 17 includes an inner movable bushing 171. The outer diameter of the transmission shaft 11 matches the inner diameter of the inner movable bushing 171. One end of the inner movable bushing 171 is slidably connected to the transmission shaft 11 via a key, and the other end of the inner movable bushing 171 is connected to the flat roller sleeve 121 to drive the flat roller sleeve 121 to move axially.

The sleeve 121 is fitted onto the inner movable bushing 171 and is slidably connected by a key. The inner movable bushing 171 is fitted with a second bearing seat 182 adjacent to the corresponding flat roller sleeve 121. Both the first bearing seat 172 and the second bearing seat 182 are provided with a first bearing 173. An inner bushing 174 is provided in each first bearing 173. The inner bushing 174 in the first bearing seat 172 is slidably connected to the drive shaft 11 by a key.

One end of the outer movable bushing 181 is slidably connected to the inner movable bushing 171 via a key, and the other end of the outer movable bushing 181 is connected to the inner bushing 174 in the second bearing seat 182. One of the two flat roller bushings 121 in the same set of flat roller assemblies is fixedly connected to the inner bushing 174 in the first bearing seat 172. The flat roller bushing 121 is driven by the inner movable bushing 171 connected to the flat roller bushing 121. 1. Axial movement, thereby driving the inner bushing 174 to move axially through the flat roller sleeve 121, and then driving the first bearing seat 172 to move axially through the first bearing 173 in the first bearing seat 172. Another flat roller sleeve 121 is fixedly connected to the inner bushing in the second bearing seat 182. The inner bushing in the second bearing seat 182 drives the second bearing seat 182 to move axially through the first bearing in the second bearing seat 182, and at the same time drives the flat roller sleeve 121 sleeved on the inner moving bushing 171 to move axially through the inner bushing in the second bearing seat 182. One of the two vertical roller shafts 122 in the same set of vertical roller assemblies is connected at both ends to the first bearing seats 172 on the two drive shafts 11, and the other vertical roller shaft 122 is connected at both ends to the second bearing seats 182 on the two drive shafts 11. The axial distance between the two vertical roller shafts 122 and the axial distance between the two flat roller sleeves 121 in the same set of flat roller assemblies on the drive shafts 11 can be adjusted by the outer moving bushing 181 and the inner moving bushing 171. This allows for the adjustment of steel profile channels of different sizes and specifications without replacing the vertical roller sleeves 123 and the flat roller sleeves 121, by only adjusting the outer moving bushing 181 and the inner moving bushing 171.

[0069] Optionally, the first drive mechanism 13 includes a first drive member (not shown in the figure), an inner moving transmission module 131, and an outer moving transmission module 132. The first drive member is connected to one end of the transmission shaft 11 and can drive the transmission shaft 11 to rotate. The inner moving transmission module 131 is connected to the inner bushing unit 17 and can drive the inner bushing unit 17 to move. The outer moving transmission module 132 is connected to the outer bushing unit 18 and can drive the outer bushing unit 18 to move. The first drive member is provided in a one-to-one correspondence with the transmission shaft 11, that is, each transmission shaft 11 is provided with a corresponding first drive member. Furthermore, the inner moving transmission module 131 includes a first reducer 1311 and a first moving sleeve 1312. The input shaft of the first reducer 1311 is connected to the transmission shaft 11, and the output shaft of the first reducer 1311 is connected to the first moving sleeve 1312. The transmission shaft 11 rotates to drive the inner moving transmission module 131 to move the inner moving sleeve 171 axially. The outer moving transmission module 132 includes a second reducer 1321 and a second moving sleeve 1322. The input shaft of the second reducer 1321 is connected to the transmission shaft 11, and the output shaft of the second reducer 1321 is connected to the second moving sleeve 1322. The transmission shaft 11 rotates to drive the outer moving transmission module 132 to move the outer moving sleeve 181 axially. In order to improve the efficiency of each... To ensure the accuracy and smoothness of the axial movement of the movable threaded sleeves and to prevent interference in the rotational movement between the movable bushings and the movable threaded sleeves, a first movable bearing 1314 is provided at the connection between the first movable threaded sleeve 1312 and the inner movable bushing 171. The first movable bearing 1314 is sleeved on the inner movable bushing 171 and sleeved on the first movable threaded sleeve 1312, and is used to transmit axial force. A second movable bearing 1324 is provided at the connection between the second movable threaded sleeve 1322 and the outer movable bushing 181. The second movable bearing 1324 is sleeved on the outer movable bushing 181 and sleeved on the second movable threaded sleeve 1322, and is used to transmit axial force. The first reducer 1311 and the second reducer 1321 can both be electric motor reducers or hydraulic motor reducers.

[0070] Optionally, to achieve the axial movement of the inner moving sleeve 171 and the outer moving sleeve 181, the moving threaded sleeve is connected to the reducer through a gear threaded sleeve fitted on the moving threaded sleeve. The outer side of the gear threaded sleeve is connected to the output shaft of the reducer through a gear, and the inner side is connected to the moving threaded sleeve through a thread, thereby driving the axial displacement of the moving threaded sleeve through the reducer (screw and nut mechanism). A first connecting piece 1313 is provided on the first moving threaded sleeve 1312, with its two ends respectively connected to the first reducer 1311 and the second reducer 1321. A second connecting piece 1323 is provided on the second moving threaded sleeve 1322, with its two ends respectively connected to the second reducer 1321 and the frame bearing seat 31, to limit the axial displacement of the gear threaded sleeve, thereby ensuring the axial displacement of the moving threaded sleeve. The outer edges of the first movable threaded sleeve 1312 and the second movable threaded sleeve 1322 are slidably connected to the first connecting member 1313 and the second connecting member 1323. Driven by the first reducer 1311 and the second reducer 1321, the first movable threaded sleeve 1312 and the second movable threaded sleeve 1322 rotate to move axially, while the first connecting member 1313 and the second connecting member 1323 remain stationary. The axial movement of the first movable threaded sleeve 1312 and the second movable threaded sleeve 1322 drives the inner movable bushing 171 and the outer movable bushing 181 to move axially, thereby driving the flat roller sleeve 121 to move axially, adjusting the axial position of the flat roller sleeve 121 on the transmission shaft. Effective width refers to the width of the portion of the flat roller sleeve 121 used to form the forming channel 124. The inner bushing 174 drives the first bearing seat 172 and the second bearing seat 182 to move axially, thereby adjusting the axial distance between the two vertical roller sleeves 123 in the same steel profile channel. The second drive mechanism adjusts the radial distance B1 between the two transmission shafts 11, thereby completing the size adjustment of the steel profile channel. The first drive component and the second drive mechanism can both be motors, cylinders, or other power components that can provide power. For example, the first drive component can be a drive motor, and the second drive mechanism can be a lifting cylinder. Specifically, the first reducer 1311 and the second reducer 1321 adjust and output their speeds, respectively driving the axial displacement of the first moving screw sleeve 1312 and the second moving screw sleeve 1322, thereby driving the adjustment of the relative displacement of the inner moving bushing 171 and the outer moving bushing 181. This achieves the adjustment of the axial distance between the two vertical roller sleeves 123 and the movement adjustment of the flat roller sleeve 121 within the same steel profile channel. In particular, when the same set of flat roller assemblies has two flat roller sleeves 121, the effective width adjustment of the flat roller assembly can be achieved 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, there are two molding units 12, which are distributed at intervals along the axial direction of the transmission shaft 11. Each transmission shaft 11 is symmetrically equipped with two sets of external moving transmission modules 132 and two sets of internal moving transmission modules 131. The two sets of external moving transmission modules 132 correspond to the two molding units 12 respectively, and the two sets of internal moving transmission modules 131 correspond to the two molding units 12 respectively. That is, each molding unit 12 is provided with two sets of external moving transmission modules 132 and two sets of internal moving transmission modules 131. The two sets of external moving transmission modules 132 are arranged on the two transmission shafts 11 respectively, and the two sets of internal moving transmission modules 131 are arranged on the two transmission shafts 11 respectively.

[0072] Optionally, the lifting adjustment mechanism 16 includes a hydraulic cylinder, a hydraulic cylinder, or a sliding locking structure. When the lifting adjustment mechanism 16 is a hydraulic cylinder, the hydraulic cylinder is installed on the corresponding first bearing seat 172 or second bearing seat 182. The output end of the hydraulic cylinder is connected to the corresponding vertical roller shaft 122. The hydraulic cylinder can stop running at any time as needed to maintain a locked state and lock in a specified position, thereby locking the vertical roller assembly in a specified position to flexibly realize the lifting adjustment of the vertical roller sleeve 123. The adjustment is simple and convenient, simplifying the structure of the vertical roller assembly. Furthermore, the end of the vertical roller shaft 122 not connected to the lifting adjustment 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 designated position. Specifically, both the first bearing seat 172 and the second bearing seat 182 are provided with sliding grooves, and the first bearing seat 172, the second bearing seat 182, and the vertical roller shaft 122 are all provided with corresponding locking holes. The vertical roller shaft 122 slides in the sliding grooves, and the locking pin cooperates with different locking holes to realize the axial movement 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 through the lifting adjustment mechanism 16, and the upper end of the vertical roller shaft 122 is connected to the corresponding bearing seat through 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 the connection via the lifting and adjusting mechanism 16; a fixed connection can also be used. Furthermore, the number and shape of the flat roller sleeves 121 in each group of flat roller assemblies can be flexibly combined according to the shape and size of the workpiece 4. Similarly, the number and shape of the vertical roller sleeves 123 in each group of vertical roller assemblies can also be flexibly combined according to the shape and size of the workpiece 4, and are not limited to the embodiments described above. The workpiece 4 can be structural steel.

[0074] The roller bending forming device 1 of the above embodiment has a simple structure. The vertical roller assembly can be adjusted for lifting and lowering independently. The adjustment of the flat roller sleeve 121 and the vertical roller sleeve 123 is more convenient and flexible, and the size of the forming channel 124 can be flexibly adjusted according to the needs.

[0075] Example 2:

[0076] See Figure 1 and Figure 7 The difference between this embodiment and Embodiment 1 is that both ends of the vertical roller shaft 122 are connected to the corresponding bearing seats by locking pins.

[0077] In the above embodiment of the roller bending forming device 1, both ends of the vertical roller shaft 122 are connected to the corresponding bearing seats through locking pins, which ensures reliable connection and low failure rate.

[0078] Example 3:

[0079] See Figure 1 and Figure 8 The difference between this embodiment and Embodiment 1 is that the upper end of the vertical roller shaft is connected to the corresponding bearing seat through the lifting adjustment mechanism 16, and the lower end of the vertical roller shaft 122 is connected to the corresponding bearing seat through the locking pin.

[0080] In the above embodiment of the roller bending forming device 1, the two ends of the vertical roller shaft 122 are respectively connected to the corresponding bearing seats through the lifting adjustment mechanism 16 and the locking pin. The connection is reliable, the adjustment is flexible and convenient, and it is easy to realize automation.

[0081] Example 4:

[0082] See Figure 1 and Figure 9 The difference between this embodiment and Embodiment 1 is that, in each forming unit 12, the upper end of the vertical roller shaft 122 of the two sets of vertical roller assemblies that is farthest from the adjacent forming unit 12 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. The upper end of the vertical roller shaft 122 of the other set 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.

[0083] In the above embodiment of the roller bending forming device 1, the vertical roller assembly can be adjusted for lifting and lowering independently, and the adjustment of the flat roller sleeve 121 and the vertical roller sleeve 123 is more convenient and flexible. The size of the forming channel 124 can be flexibly adjusted according to the needs, which facilitates automation.

[0084] Example 5:

[0085] See Figure 1 and Figure 10The difference between this embodiment and Embodiment 1 is that, in each forming unit 12, the upper end of the vertical roller shaft 122 of the vertical roller assembly furthest from the adjacent forming unit 12 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. The upper end of the vertical roller shaft of the other set 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. In other words, the two sets of vertical roller assemblies in each forming unit 12 adopt a vertically cross sliding adjustment, that is, the upper end of one set of vertical roller assemblies is connected to the corresponding bearing seat through a lifting adjustment mechanism 16, and the lower end of the other set of vertical roller assemblies is connected to the corresponding bearing seat through a lifting adjustment mechanism 16.

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

[0087] Example 6:

[0088] See Figure 1 and Figure 11 The difference between this embodiment and Embodiment 1 is that the lower end of each vertical roller shaft 122 is connected to the corresponding bearing seat through the lifting adjustment mechanism 16, and the upper end of each vertical roller shaft 122 is slidably connected to the corresponding bearing seat. Specifically, each bearing seat corresponding to each vertical roller shaft 122 is provided with a sliding groove, and the upper end of the vertical roller shaft 122 extends into the sliding groove and can slide within the sliding groove. The sliding cooperation between the upper end of the vertical roller shaft 122 and the corresponding bearing seat provides movement space for the lifting adjustment mechanism 16 to drive the vertical roller shaft 122 to rise and fall.

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

[0090] Example 7:

[0091] See Figure 1 and Figure 12The difference between this embodiment and embodiment five 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 end to end to form a forming channel 124. The flat roller sleeves 121 of the two sets of flat roller assemblies are the upper flat roller sleeve and the lower flat roller sleeve, respectively. The vertical roller sleeve 123 of the first vertical roller assembly is the first vertical roller sleeve, and the vertical roller sleeve 123 of the second vertical roller assembly is the second vertical roller sleeve. The beginning end of the upper flat roller sleeve and the end end of the second vertical roller sleeve partially overlap in the axial direction of the upper flat roller sleeve. The overlap length and width can be X11, and the upper flat roller sleeve is located above the second vertical roller sleeve. The first end of the lower flat roller sleeve overlaps with the tail end of the first vertical roller sleeve in the axial direction of the second vertical roller sleeve, with an overlap width of Y11. The second vertical roller sleeve is located on the side of the lower flat roller sleeve closer to the adjacent forming unit 12. The first end of the lower flat roller sleeve overlaps with the tail end of the first vertical roller sleeve in the axial direction of the lower flat roller sleeve, with an overlap width of X12. The lower flat roller sleeve is located below the first vertical roller sleeve. The first end of the first vertical roller sleeve overlaps with the tail end of the upper flat roller sleeve in the axial direction of the first vertical roller sleeve, with an overlap width of 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 first end of the upper flat roller sleeve refers to the end closer to the adjacent forming unit 12, the first 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 closer 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; or, each flat roller assembly includes two flat roller sleeves 121 distributed axially along the drive shaft 11, 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 synchronously with the outer bushing unit 18 along the axial direction of the drive shaft 11, and the other flat roller sleeve 121 can move synchronously with the inner bushing unit 17 along the axial direction of the drive shaft 11. That is, one of the two flat roller sleeves 121 and one of the two vertical roller sleeves 123 can move synchronously with the same outer bushing unit 18, and the other flat roller sleeve 121 and the other vertical roller sleeve 123 can move synchronously with the same inner bushing unit 17. Furthermore, the flat roller sleeve 121 is connected to the vertical roller shaft 122 at one end by a lifting and adjusting mechanism 16, and can move together along the axial direction of the drive shaft 11. This allows it to adapt to the forming of steel with different shapes of open or closed structures, and also allows it to control the deformation dimensions of the forming channel, thereby improving the quality of the formed product. Specifically, the distance between the two flat roller sleeves 121 is Y1, and the distance between the two vertical roller sleeves 123 is X1. When the first driving component, the second driving mechanism, and the lifting and adjusting mechanism 16 operate, they drive each vertical roller sleeve 123 and each flat roller sleeve 121 to move closer to the center of the forming channel 124, making the dimensions of the forming channel 124 smaller, i.e., X1 and Y1 become smaller.

[0093] In addition to the advantages of the roller bending forming device 1 in Embodiment 5, the vertical roller sleeve 123 and the horizontal roller sleeve 121 can cooperate to form a closed forming channel 124, which increases the contact area between the vertical roller sleeve, the horizontal roller sleeve 121 and the workpiece 4. Especially when the size of the workpiece 4 is large, the closed forming channel 124 can ensure the forming quality of the workpiece 4. In addition, the forming channel 124 can always remain closed as the size of the forming channel 124 decreases, making it flexible in application and adaptable to a wide range of applications.

[0094] Example 8:

[0095] See Figure 1 and Figure 13The difference between this embodiment and embodiment seven is that the first 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, with an overlap width of X21, and the upper flat roller sleeve is located above the second vertical roller sleeve. The first end of the second vertical roller sleeve and the tail end of the lower flat roller sleeve partially overlap in the axial direction of the second vertical roller sleeve, with an overlap width of Y21, and the second vertical roller sleeve is located on the side of the lower flat roller sleeve closer to the adjacent forming unit 12. The first end of the lower flat roller sleeve and the tail end of the first vertical roller sleeve partially overlap in the axial direction of the lower flat roller sleeve, with an overlap width of X22, and the lower flat roller sleeve is located below the first vertical roller sleeve. The first end of the first vertical roller sleeve and the tail end of the upper flat roller sleeve partially overlap in the axial direction of the first vertical roller sleeve, with an overlap width of Y22, and the first vertical roller sleeve is located on the side of the upper flat roller sleeve away from the adjacent forming unit 12. 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 component, the second driving mechanism, and the lifting adjustment mechanism 16 operate, they drive each vertical roller sleeve 123 and each flat roller sleeve 121 to move away from the center of the forming channel 124, thereby increasing the size of the forming channel 124, i.e., X2 and Y2 become larger.

[0096] In the above embodiment of the roll forming device 1, the vertical roller sleeve 123 and the horizontal roller sleeve 121 can cooperate to form a closed forming channel 124, which increases the contact area between the vertical roller sleeve and the horizontal roller sleeve 121 and the workpiece 4. Especially when the size of the workpiece 4 is large, the closed forming channel 124 can ensure the forming quality of the workpiece 4. In addition, the forming channel 124 can always remain closed as the size of the forming channel 124 increases, making it flexible in application and adaptable to a wide range of applications.

[0097] See Figures 1 to 13 In some optional embodiments, this application also provides an adjustment method for the roll forming apparatus 1 as described in any of the above embodiments, comprising:

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

[0099] The second drive mechanism is activated, which drives the vertical roller assembly and the flat roller assembly to rise and fall to a preset position along the axial direction of the vertical roller assembly, thereby adjusting the size of the forming channel 124 along the axial direction of the vertical roller assembly; or, the second drive mechanism and the lifting adjustment mechanism 16 are activated, which work together to move the vertical roller assembly and the flat roller assembly along the axial direction of the vertical roller assembly to a preset position, thereby adjusting the size of the forming channel 124 along the axial direction of the vertical roller assembly; or, the lifting adjustment mechanism 16 is activated, which drives the vertical roller assembly to move along the axial direction of the vertical roller assembly to a preset position, allowing for independent adjustment of the vertical roller assembly's lifting position, thus providing greater flexibility.

[0100] The adjustment method described in the above embodiment is simple and convenient to operate, and can quickly and flexibly adjust the size of the molding channel 124 according to needs, thereby improving production efficiency.

[0101] See Figures 1 to 5 , Figures 14 to 23 In some optional embodiments, this application also provides a disassembly / assembly device 2 for disassembling and assembling the roll forming apparatus 1 of any of the above embodiments. The disassembly / assembly device 2 of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. However, it should be understood that the disassembly / assembly device 2 of this application is not limited to the following embodiments.

[0102] Implementation 1:

[0103] See Figures 1 to 5 , Figures 14 to 16 , Figures 19 to 23 The disassembly and assembly device 2 in this embodiment includes a base 201, multiple support sliders 202, and a pusher / puller 203. The multiple support sliders 202 are slidably mounted on the base 201 to support the inner bushing unit 17, the outer bushing unit 18, and the frame bearing unit 3. The number of support sliders 202 can be selected according to requirements. The cylinder of the pusher / puller 203 is fixedly connected to or hinged to the base 201. The output end of the pusher / puller 203 is provided with a slide head 204 slidably connected to the base 201. The slide head 204 is provided with a swing hook 206 that is hooked to the support sliders 202. The slidable connection between the slide head 204 and the base 201 serves as a guide, which helps improve the stability and reliability of the pusher / puller 203. When the swing hook 206 is connected to the support slider 202, the pusher / puller 203 moves, causing the support slider 202 to move. The support slider 202 is provided with a hook 205, and the swing hook 206 can flip to connect or disconnect from the hook 205; that is, the support slider 202 and the slide head are detachably connected.

[0104] Optionally, the number of push-pull devices 203 can be multiple, and the distribution of the multiple push-pull devices 203 can be set according to requirements. Further, the number of push-pull devices 203 can be four, to accommodate the stroke requirements of different moving positions of the components to be disassembled; for example, when the stroke position is close to the middle of the drive shaft 11, the component to be disassembled can be moved by the push-pull device 203 near the middle of the drive shaft 11; when the stroke position is close to the end of the drive shaft 11, the component to be disassembled can be moved by the push-pull devices 203 near both ends of the drive shaft 11. This layout has lower stroke requirements for the push-pull devices, which helps to reduce the stroke requirements of the push-pull devices, reduce the occupation of workshop space, and facilitate disassembly and assembly, improving disassembly and assembly efficiency.

[0105] Optionally, the disassembly and assembly device also includes a drive shaft support block, which can be mounted on the base to support the drive shaft 11. Furthermore, the drive shaft support block can slide along the axial direction of the drive shaft 11 so that it can be supported at different positions on the drive shaft 11 as needed.

[0106] Optionally, the support slider 202 is equipped with a jack 207. The jack 207 moves up and down to abut against the corresponding inner bushing unit 17, outer bushing unit 18 and frame bearing unit 3 for support. The height of the inner bushing unit 17, outer bushing unit 18 and frame bearing unit 3 can be adjusted by lifting and lowering the jack 207, thereby ensuring that the support slider 202 is fully engaged with the frame bearing seat 31 of the inner bushing unit 17, outer bushing unit 18 and frame bearing unit 3, and ensuring the stability and reliability of the support. Furthermore, multiple support sliders 202 are respectively configured to correspond to the first bearing seat 172, the second bearing seat 182, and the frame bearing seat 31. That is, the support sliders 202 support and cooperate 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 sliders 202 and can move together with the support sliders 202 under their own weight, or they can be connected to the support sliders 202 through connectors to ensure that they move together with the support sliders 202. 2. Move together; wherein, the support 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, or it can 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 equipped with displacement sensors, which can measure the displacement of the support slider 202 driven by the second push-pull devices 203 in a timely manner.

[0107] Optionally, the shape of the part of the support slider 202 that mates with the corresponding bearing seat matches the shape of the corresponding bearing seat. The shape of the part 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. In this embodiment, the shape of the part of the support slider 202 that mates with the corresponding bearing seat is rectangular.

[0108] Optionally, the disassembly and assembly device 2 also includes a lifting mechanism for lifting the vertical roller assembly. The lifting mechanism includes a vertical roller frame 208, which has lifting lugs 209 and mounting holes 210 corresponding to the vertical roller assembly. Further, the lifting lugs 209 can be connected to the hooks 211 of a workshop crane via lifting ropes 212. The mounting hole 210 includes an assembly part 2101 and a lifting part 2102. The diameter D1 of the lifting part 2102 is smaller than the diameter D2 of the assembly part 2101, and the diameter D2 of the assembly part 2101 is larger than the maximum diameter of the vertical roller sleeve 123. The diameter D1 of the lifting part 2102 is smaller than the maximum diameter of the vertical roller sleeve 123, thus preventing the vertical roller assembly from detaching from the lifting part 2102 during the lifting process. The vertical roller frame 208 is moved above the vertical roller assembly, with the center of the vertical roller assembly aligned with the center of the assembly part 2101. The vertical roller frame 208 is lowered so that the upper end of the vertical roller assembly passes through the assembly part 2101, and the maximum diameter portion of the vertical roller sleeve 123 is located above the assembly part 2101. The vertical roller frame 208 is translated so that the vertical roller assembly moves into the lifting part 2102, and the maximum diameter portion of the vertical roller sleeve 123 restricts the vertical roller sleeve 123 from disengaging from the lifting part 2102. The vertical roller frame 208 is moved to lift the vertical roller assembly to the designated position.

[0109] The disassembly and assembly device 2 in the above embodiment has a simple structure and is easy to disassemble and assemble. With the assistance of the disassembly and assembly device 2, the vertical roller assembly, flat roller assembly, inner bushing unit 17, outer bushing unit 18 and other components of the roller bending forming device 1 can be quickly assembled, disassembled, replaced and adjusted, thereby quickly completing the disassembly and replacement of the roller bending forming device 1, so as to adapt to the production of workpieces 4 with different shapes and specifications and different sizes, improve product quality, save replacement time, improve production efficiency, and also help reduce the inventory of production spare parts and reduce costs.

[0110] Example 2:

[0111] See Figure 17 The difference between this embodiment and Embodiment 1 is that the shape of the part where the support slider 202 mates with the corresponding bearing seat is trapezoidal.

[0112] The disassembly and assembly device 2 in the above embodiment can adapt to the support of the trapezoidal bearing seat, thereby improving the stability and reliability of the support.

[0113] Example 3:

[0114] See Figure 18 The difference between this embodiment and Embodiment 1 is that the shape of the part where the support slider 202 mates with the corresponding bearing seat is arc-shaped.

[0115] The disassembly and assembly device 2 in the above embodiment can adapt to the support of the arc-shaped bearing seat, thereby improving the stability and reliability of the support.

[0116] See Figures 1 to 4 , Figures 14 to 16 , Figures 19 to 22 In some optional embodiments, this application also provides a method for disassembling and assembling the roll forming apparatus 1 as described in any of the above embodiments. This method is implemented using the disassembly and assembly device 2 as described in any of the above embodiments, and includes:

[0117] Disconnect the frame bearing unit 3, inner bushing unit 17, and outer bushing unit 18 from the corresponding drive shaft 11, allowing them to move axially along the drive shaft 11 and slide out from its end, thus detaching from the drive shaft 11 for lifting and maintenance replacement by the lifting mechanism. Specifically, the limiting end caps installed at both ends of the drive shaft 11 can be removed from the drive shaft 11, allowing the frame bearing unit 3, inner bushing unit 17, and outer bushing unit 18 to slide out from the end of the drive shaft 11. The frame bearing unit 3, outer bushing unit 18, and inner bushing unit 17 are then sequentially moved away from the end of the drive shaft 11, and connected together so that they can move together.

[0118] The push-pull mechanism 203 drives the frame bearing unit 3, inner bushing unit 17, and outer bushing unit 18 to move axially along the drive shaft 11 until they disengage from the drive shaft 11 and reach a first preset position. Upon reaching the first preset position, the connection between the frame bearing unit 3 and the outer bushing unit 18 is disconnected, and the frame bearing unit 3 no longer moves with the outer bushing unit 18. Alternatively, the frame bearing unit 3 can be fixed in the first preset position to prevent it from moving when the outer bushing unit 18 moves. Specifically, the frame bearing unit 3, inner bushing unit 17, and outer bushing unit 18 are connected together, and the support slider 202 is supported by the first bearing seat 172 of the inner bushing unit 17. At the bottom, the first bearing seat 172 can be directly placed on the support slider 202 and fixed to the support slider 202 by a locking mechanism to prevent the first bearing seat 172 from disengaging from the support slider 202 during movement. The swing hook 206 of the flip push-pull device 203 is hooked and connected to the hook 205 of the support slider 202. The operation of the push-pull device 203 drives the support slider 202 corresponding to the inner bushing unit 17 to move by a stroke A2, that is, the frame bearing unit 3, the inner bushing unit 17, and the outer bushing unit 18 move from the initial position to the first preset position. When the first preset position is reached, the frame bearing unit 3, the inner bushing unit 17, and the outer bushing unit 18 are all disengaged from the drive shaft 11. At the initial position, the distance between the frame bearing seats 31 is A1. The support slider 202 can also be supported and connected to the second bearing seat 182 or the frame bearing seat 31. During disassembly, the support slider 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 push-pull mechanism 203 drives the outer bushing unit 18 and the inner bushing unit 17 to move together axially away from the drive shaft 11 to a second preset position. After reaching the second preset position, the connection between the outer bushing unit 18 and the inner bushing unit 17 is disconnected, and the outer bushing unit 18 no longer moves together with the inner bushing unit 17. Alternatively, the outer bushing unit 18 can be fixed in the second preset position to prevent the inner bushing unit 17 from driving the outer bushing unit 18 when it moves. The outer bushing unit 18 moves; specifically, the outer bushing unit 18 is connected to the inner bushing unit 17, and the swing hook 206 of the flip push-pull device 203 is hooked to the hook 205 of the support slider 202. The push-pull device 203 moves the support slider 202 corresponding to the inner bushing unit 17 by a stroke A3, that is, the inner bushing unit 17 and the outer bushing unit 18 move from the first preset position to the second preset position. When the second preset position is reached, the inner bushing unit 17 and the outer bushing unit 18 are completely disengaged from the frame bearing unit 3.

[0120] The push-pull mechanism 203 drives the inner bushing unit 17 to move axially away from the drive shaft 11 to a third preset position, with the first, second, and third preset positions sequentially moving away from the end of the drive shaft 11. Specifically, the swing hook 206 of the flip push-pull mechanism 203 is hooked and connected to 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 bushing unit 17 to move a distance A4, that is, the inner bushing unit 17 moves from the second preset position to the third preset position. When it reaches the third preset position, the inner bushing unit 17 is completely disengaged from the outer bushing unit 18, and the disassembly is completed. After disassembly, replace the corresponding vertical roller assembly and horizontal roller assembly. After replacing the vertical roller assembly and horizontal roller assembly, assemble the inner bushing unit 17, outer bushing unit 18, and frame bearing seat 31 in the reverse order of disassembly.
