Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical equipment, and particularly to a roll bending forming device, an adjustment method, a mounting / demounting device, and a mounting / demounting method.

Background Art

[0002] Currently, in the cold forming technology of structural steel, single-pass forming is adopted. The structure of the forming device is simple, but it can only be dealt with by manual adjustment or mechanical adjustment, so on-line adjustment is not possible, the production quality is low, and the production efficiency is also low. The hot bending forming technology of structural steel directly utilizes the waste heat after rolling of the slab to perform roll bending forming, and has less environmental impact. However, whether it is cold forming technology or hot forming technology, when manufacturing structural steel of different specifications or shapes with the same roll bending forming device, it is necessary to frequently replace the forming roll sleeve, or the forming roll sleeve has to be moved integrally with the drive shaft to adjust the position, and it cannot be adjusted independently. Therefore, there are problems that the standard adjustment of the forming passage is inconvenient, the production efficiency is low, and the cost is high.

[0034] Before describing embodiments of the present invention in detail, the application environment of the present invention will be described. The technology of the present invention is mainly applied to the metallurgical equipment technology field, and in particular to the forming of structural steel. For example, it is used for high-strength preheat forming of hot-rolled strips (generally 5 mm to 60 mm thick and 600 mm to 5500 mm wide). The present invention solves the problem that the forming passage dimensional adjustment is monolithic and that the forming roll sleeve must be frequently replaced for dimensional adjustment in the conventional forming process of structural steel, which lacks flexibility.

[0035] Referring to Figures 1 to 13, the present invention provides a roll bending forming apparatus 1 in several preferred embodiments. The roll bending forming apparatus 1 of the present invention will be described in detail below based on the accompanying drawings and specific embodiments, but it should be understood that the roll bending forming apparatus 1 of the present invention is not limited to the following embodiments.

[0036] Example 1:

[0037] Referring to Figures 1 to 6, the roll bending forming apparatus 1 of this embodiment comprises a frame, two drive shafts 11, at least one forming unit 12, a first drive mechanism 13, a second drive mechanism, and a lifting adjustment mechanism 16. The two drive shafts 11 are mounted to the frame via a frame bearing unit 3, and the two drive shafts 11 are arranged parallel to each other and spaced apart in the vertical direction. The frame bearing unit 3 includes a frame bearing housing 31 and a frame bearing 32, the frame bearing housing 31 is connected to the frame, and the drive shafts 11 are rotatably mounted to the frame bearing housing 31 via the frame bearing 32, thereby allowing the drive shafts 11 to rotate in the axial direction of their own axis.

[0038] Each molding unit 12 includes two sets of flat roll members and two sets of vertical roll members, the two sets of flat roll members each being attached to the two drive shafts 11, and both ends of each vertical roll member each being connected to the two drive shafts 11. The flat roll members and the vertical roll members surround the molding passage 124, and the flat roll members and the vertical roll members are arranged alternately in the circumferential direction of the molding passage 124.

[0039] The first drive mechanism 13 is connected to the flat roll member and the vertical roll member, and moves them in the axial direction of the drive shaft 11. The axial direction of the flat roll member is parallel to the axial direction of the drive shaft 11, and the axial direction of the vertical roll member is perpendicular to the axial direction of the drive shaft 11.

[0040] The second drive mechanism is provided to adjust the distance B1 between the two drive shafts 11. The second drive mechanism is connected to the drive shafts 11 and, by operation, moves the drive shafts 11 closer to or further away from each other, thereby adjusting the distance B1 between the two drive shafts 11. Here, the distance B1 refers to the distance between the first centerlines 111 of the two drive shafts 11.

[0041] At least one end of the vertical roll member is connected to the drive shaft 11 via the lifting adjustment mechanism 16, and the lifting adjustment mechanism 16 can raise and lower the vertical roll member in its axial direction and lock it in a predetermined position, and can move synchronously with the corresponding vertical roll member in the axial direction of the drive shaft 11.

[0042] In this way, the first drive mechanism 13, the second drive mechanism, and the lifting adjustment mechanism 16 drive and move the flat roll member and the vertical roll member, thereby adjusting the dimensions of the molding passage 124.

[0043] Preferably, an inner sleeve unit 17 and an outer sleeve unit 18 are coaxially mounted on each drive shaft 11, and these are movable in the axial direction relative to the drive shaft 11. The inner sleeve unit 17 is fitted onto the drive shaft 11, and the outer sleeve unit 18 is fitted onto the inner sleeve unit 17.

[0044] Of the two sets of vertical roll members of the same molding unit 12, the vertical roll member furthest from the adjacent molding unit 12 is the first vertical roll member, and the other vertical roll member closer to the adjacent molding unit 12 is the second vertical roll member. Both ends of the first vertical roll member are connected to the outer sleeve units 18 on the two drive shafts 11, and both ends of the second vertical roll member are connected to the inner sleeve units 17 on the two drive shafts 11.

[0045] The first drive mechanism is connected to the inner sleeve unit 17 and the outer sleeve unit 18, and via these, moves the first vertical roll member and the second vertical roll member in the axial direction of the drive shaft 11.

[0046] Furthermore, both the first and second vertical roll members include a vertical roll shaft 122 and a vertical roll sleeve 123, the vertical roll sleeve 123 being fitted onto the vertical roll shaft 122 and rotatable relative to the vertical roll shaft 122. At least one end of the vertical roll shaft 122 of the first vertical roll member is connected to the corresponding outer sleeve unit 18 via the lifting adjustment mechanism 16, and at least one end of the vertical roll shaft 122 of the second vertical roll member is connected to the corresponding inner sleeve unit 17 via the lifting adjustment mechanism 16. Specifically, the lower end of the vertical roll shaft 122 of the first vertical roll member is connected to the corresponding outer sleeve unit 18 via the lifting adjustment mechanism 16, and the lower end of the vertical roll shaft 122 of the second vertical roll member is connected to the inner sleeve unit 17 via the lifting adjustment mechanism 16.

[0047] Preferably, the flat roll member includes a flat roll sleeve 121, the flat roll sleeve 121 is connected to an outer sleeve unit 18 and is movable in the axial direction of the drive shaft 11 together with the outer sleeve unit 18. Alternatively, the flat roll sleeve 121 is connected to an inner sleeve unit 17 and is movable in the axial direction of the drive shaft 11 together with the inner sleeve unit 17. The flat roll sleeve 121 and the vertical roll sleeve 123 cooperate to enclose the forming passage 124, specifically, the outer wall of the flat roll sleeve 121 and the outer wall of the vertical roll sleeve 123 cooperate to form the forming passage 124.

[0048] Furthermore, at least one of the two sets of flat roll members of each molding unit 12 includes two flat roll sleeves 121 arranged along the axial direction of the drive shaft 11, with one of these two flat roll sleeves 121 connected to the outer sleeve unit 18 and the other connected to the inner sleeve unit 17.

[0049] In this embodiment, each flat roll member includes two flat roll sleeves 121. Of the two flat roll sleeves 121 belonging to the same flat roll member, one is fitted onto the drive shaft 11 and connected to the outer sleeve unit 18, and is movable in the axial direction of the drive shaft 11 together with the outer sleeve unit 18, while the other is connected to the inner sleeve unit 17 and is movable in the axial direction of the drive shaft 11 together with the inner sleeve unit 17.

[0050] Preferably, the inner sleeve unit 17 includes an inner moving sleeve 171, the outer diameter of the drive shaft 11 matches the inner diameter of the inner moving sleeve 171, one end of the inner moving sleeve 171 is slidably connected to the drive shaft 11 by a key, and the other end is connected to the flat roll sleeve 121, thereby allowing the flat roll sleeve 121 to move in the axial direction.

[0051] Of the two flat roll sleeves 121 belonging to the same flat roll member, one flat roll sleeve 121 is fitted onto the drive shaft 11 and slidably connected by a key, and a first bearing housing 172 is fitted on the drive shaft 11 adjacent to the corresponding flat roll sleeve 121. The other flat roll sleeve 121 is fitted onto the internal moving sleeve 171 and slidably connected by a key, and a second bearing housing 182 is fitted on the internal moving sleeve 171 adjacent to the corresponding flat roll sleeve 121.

[0052] The first bearing housing 172 and the second bearing housing 182 are each provided with a first bearing 173, and an inner sleeve 174 is provided inside each first bearing 173. The inner sleeve 174 in the first bearing housing 172 is slidably connected to the drive shaft 11 by a key, and the inner sleeve 174 in the second bearing housing 182 is slidably connected to the inner moving sleeve 171 by a key. The first bearing 173 may specifically be a tapered roller bearing.

[0053] The outer sleeve unit 18 includes an outer moving sleeve 181, the outer diameter of the inner moving sleeve 171 matches the inner diameter of the outer moving sleeve 181, one end of the outer moving sleeve 181 is slidably connected to the inner moving sleeve 171 by a key, and the other end is connected to the inner sleeve 174 in the second bearing housing 182.

[0054] Of the two flat roll sleeves 121 belonging to the same flat roll member, one flat roll sleeve 121 is fixedly connected to the inner sleeve 174 in the first bearing housing 172, and the flat roll sleeve 121 can be moved axially via the inner moving sleeve 171 connected to the flat roll sleeve 121, and further the inner sleeve 174 can be moved axially, thereby moving the first bearing housing 172 axially via the first bearing 173 of the first bearing housing 172. The other flat roll sleeve 121 is fixedly connected to the inner sleeve 174 in the second bearing housing 182, and the inner sleeve 174 in the second bearing housing 182 can move the second bearing housing 182 axially via the first bearing 173 of the second bearing housing 182, and at the same time the flat roll sleeve 121 fitted to the inner moving sleeve 171 can be moved axially via the inner sleeve 174 in the second bearing housing 182.

[0055] Furthermore, of the two vertical roll shafts 122 belonging to the same vertical roll member, both ends of one vertical roll shaft 122 are connected to the first bearing housing 172 on the two drive shafts 11, and both ends of the other vertical roll shaft 122 are connected to the second bearing housing 182 on the two drive shafts 11. This allows the outer moving sleeve 181 and the inner moving sleeve 171 to adjust the axial distance between the two vertical roll shafts 122, and the axial distance between the two flat roll sleeves 121 belonging to the same flat roll member on the drive shaft 11. Therefore, without replacing the vertical roll sleeves 123 and the flat roll sleeves 121, the structure can be adapted to structural steel passages of different dimensions simply by adjusting the outer moving sleeve 181 and the inner moving sleeve 171.

[0056] Preferably, the first drive mechanism 13 includes a first drive member (not shown), an inner moving transmission module 131, and an outer moving transmission module 132. The first drive member is connected to one end of the drive shaft 11 and can rotate the drive shaft 11. The inner moving transmission module 131 is connected to the inner sleeve unit 17 and can move the inner sleeve unit 17, and the outer moving transmission module 132 is connected to the outer sleeve unit 18 and can move the outer sleeve unit 18. Here, the first drive member is provided in one-to-one correspondence with the drive shaft 11, that is, one first drive member is provided for each drive shaft 11.

[0057] Furthermore, the internal moving transmission module 131 includes a first reduction gear 1311 and a first moving nut 1312, the input shaft of the first reduction gear 1311 being connected to the drive shaft 11 and the output shaft of the first reduction gear 1311 being connected to the first moving nut 1312. The rotation of the drive shaft 11 drives the internal moving transmission module 131, causing the internal moving sleeve 171 to move in the axial direction.

[0058] The external moving transmission module 132 includes a second reduction gear 1321 and a second moving nut 1322. The input shaft of the second reduction gear 1321 is connected to the drive shaft 11, and the output shaft of the second reduction gear 1321 is connected to the second moving nut 1322. The rotation of the drive shaft 11 drives the external moving transmission module 132, causing the external moving sleeve 181 to move in the axial direction.

[0059] Furthermore, in order to improve the accuracy and stability of the axial movement of each movable nut, and to prevent rotational interference between each movable sleeve and each movable nut, a first movable bearing 1314 is provided at the connection between the first movable nut 1312 and the inner movable sleeve 171. The first movable bearing 1314 is fitted externally to the inner movable sleeve 171 and internally to the first movable nut 1312, and is used to transmit axial force. Similarly, a second movable bearing 1324 is provided at the connection between the second movable nut 1322 and the outer movable sleeve 181. The second movable bearing 1324 is fitted externally to the outer movable sleeve 181 and internally to the second movable nut 1322, and is used to transmit axial force.

[0060] Here, the first reduction gear 1311 and the second reduction gear 1321 may both be motor reduction gears or hydraulic motor reduction gears.

[0061] Preferably, in order to achieve axial movement of the inner moving sleeve 171 and the outer moving sleeve 181, the moving nut and the reduction gear are connected via a gear nut fitted onto the moving nut. The outside of the gear nut is connected to the output shaft of the reduction gear by a gear, and the inside is screw-connected to the moving nut. This allows the reduction gear to drive the moving nut and displace it in the axial direction (screw-shaft-nut mechanism).

[0062] A first connecting member 1313 is provided on the first movable nut 1312, with both ends connected to the first reduction gear 1311 and the second reduction gear 1321, respectively. A second connecting member 1323 is provided on the second movable nut 1322, with both ends connected to the second reduction gear 1321 and the frame bearing housing 31, respectively. This restricts the axial displacement of the gear nut and ensures that the axial displacement of the movable nut is performed reliably.

[0063] The outer edges of the first moving nut 1312 and the second moving nut 1322 are slidably connected to the first connecting member 1313 and the second connecting member 1323, respectively, and the first moving nut 1312 and the second moving nut 1322 rotate and move axially when driven by the first reduction gear 1311 and the second reduction gear 1321. At this time, the first connecting member 1313 and the second connecting member 1323 are fixed, and the first moving nut 1312 and the second moving nut 1322 move axially, causing the inner moving sleeve 171 and the outer moving sleeve 181 to move axially, and further moving the flat roll sleeve 121 axially. This makes it possible to adjust the effective width of the flat roll sleeve 121 in the axial direction of the drive shaft 11. Here, the effective width refers to the width of the portion of the flat roll sleeve 121 that surrounds the forming passage 124.

[0064] Furthermore, the first bearing housing 172 and the second bearing housing 182 can be moved axially via the inner sleeve 174, thereby adjusting the axial distance between the two vertical roll sleeves 123 within the same structural steel passage. In addition, the second drive mechanism can adjust the radial distance B1 between the two drive shafts 11, thereby adjusting the dimensions of the structural steel passage.

[0065] Here, the first drive member and the second drive mechanism may both be a motor, a hydraulic cylinder, or other power supply member. For example, the first drive member may be a drive motor, and the second drive mechanism may be a lifting hydraulic cylinder.

[0066] Specifically, the first reduction gear 1311 and the second reduction gear 1321 adjust their rotational speed and output power, driving the axial displacement of the first moving nut 1312 and the second moving nut 1322, respectively, thereby adjusting the relative displacement of the inner moving sleeve 171 and the outer moving sleeve 181. This makes it possible to adjust the axial distance between two of the vertical roll sleeves 123 within the same structural steel passage and to adjust the movement of the flat roll sleeve 121. In particular, when the same flat roll member has two flat roll sleeves 121, the effective width of the flat roll member can be adjusted by adjusting the gap width between the two flat roll sleeves 121, thereby adjusting the width dimension of the forming passage 124 in the axial direction of the drive shaft 11.

[0067] Preferably, there are two molding units 12, and the two molding units 12 are spaced apart along the axial direction of the drive shaft 11. Two sets of outer moving transmission modules 132 and two sets of inner moving transmission modules 131 are provided symmetrically on each drive shaft 11, with each of the two sets of outer moving transmission modules 132 corresponding to the two molding units 12, and each of the two sets of inner moving transmission modules 131 corresponding to the two molding units 12. That is, each molding unit 12 is provided with two sets of outer moving transmission modules 132 and two sets of inner moving transmission modules 131, with each of the two sets of outer moving transmission modules 132 positioned on the two drive shafts 11, and each of the two sets of inner moving transmission modules 131 also positioned on the two drive shafts 11.

[0068] Preferably, the lifting adjustment mechanism 16 includes a cylinder, a hydraulic cylinder, or a sliding locking mechanism. If the lifting adjustment mechanism 16 is a cylinder, the cylinder is provided in the corresponding first bearing housing 172 or second bearing housing 182, and the output end of the cylinder is connected to the corresponding vertical roll shaft 122. The cylinder can stop operating as needed to maintain a locked state and lock in a predetermined position, thereby fixing the vertical roll member in a predetermined position. This allows for flexible lifting adjustment of the vertical roll sleeve 123, simplifies adjustment, and simplifies the structure of the vertical roll member.

[0069] Furthermore, the end of the vertical roll shaft 122 that is not connected to the lifting adjustment mechanism 16 is slidably connected to the corresponding first bearing housing 172 or second bearing housing 182, and is locked by a lock pin when the vertical roll shaft 122 is raised or lowered to a predetermined position. Specifically, the first bearing housing 172 and the second bearing housing 182 are each provided with a sliding groove, and the first bearing housing 172, the second bearing housing 182, and the vertical roll shaft 122 are each provided with a corresponding lock hole. The vertical roll shaft 122 slides within the sliding groove, and the axial movement of the vertical roll shaft 122 is adjusted by engaging the lock pin with a different lock hole.

[0070] In this embodiment, the lower end of each vertical roll shaft 122 is connected to the corresponding bearing housing via the lifting adjustment mechanism 16, and the upper end of each vertical roll shaft 122 is connected to the corresponding bearing housing via a locking pin.

[0071] As can be understood, the connection method between the vertical roll shaft 122 and the corresponding bearing housing is not limited to connection via the lifting adjustment mechanism 16, but a fixed connection may also be employed. Furthermore, the number and shape of the flat roll sleeves 121 in each flat roll member can be flexibly combined according to the shape and size of the workpiece 4, and the number and shape of the vertical roll sleeves 123 in each vertical roll member can also be flexibly combined according to the shape and size of the workpiece 4, and are not limited to the above-described embodiment. Here, the workpiece 4 may be structural steel.

[0072] The roll bending apparatus 1 of the above embodiment has a simple structure, the vertical roll member can be raised and lowered independently, the adjustment of the flat roll sleeve 121 and the vertical roll sleeve 123 is easier and more flexible, and the size of the forming passage 124 can be flexibly adjusted as required.

[0073] Example 2:

[0074] Referring to Figures 1 and 7, this embodiment differs from Embodiment 1 in that both ends of the vertical roll shaft 122 are connected to the corresponding bearing housings via lock pins.

[0075] In the roll bending apparatus 1 of this embodiment, both ends of the vertical roll shaft 122 are connected to the corresponding bearing housings via lock pins, resulting in a highly reliable connection and a low failure rate.

[0076] Example 3:

[0077] Referring to Figures 1 and 8, this embodiment differs from Embodiment 1 in that the upper end of the vertical roll shaft 122 is connected to the corresponding bearing housing via the lifting adjustment mechanism 16, and the lower end of the vertical roll shaft 122 is connected to the corresponding bearing housing via a locking pin.

[0078] In the roll bending apparatus 1 of this embodiment, both ends of the vertical roll shaft 122 are connected to corresponding bearing housings via a lifting adjustment mechanism 16 and a locking pin, respectively. The connection is highly reliable, adjustment is flexible and easy, and it is suitable for achieving automation.

[0079] Example 4:

[0080] Referring to Figures 1 and 9, this embodiment differs from Embodiment 1 in that, of the two sets of vertical roll members in each molding unit 12, the upper end of the vertical roll shaft 122 of the vertical roll member furthest from the adjacent molding unit 12 is connected to the corresponding bearing housing via a locking pin, and its lower end is connected to the corresponding bearing housing via a lifting adjustment mechanism 16. On the other hand, the upper end of the vertical roll shaft 122 of the other vertical roll member is connected to the corresponding bearing housing via a lifting adjustment mechanism 16, and its lower end is connected to the corresponding bearing housing via a locking pin.

[0081] In the roll bending forming apparatus 1 of this embodiment, each vertical roll member can be individually raised and lowered, the adjustment of the flat roll sleeve 121 and the vertical roll sleeve 123 is easier and more flexible, and the size of the forming passage 124 can be flexibly adjusted as required, making it suitable for achieving automation.

[0082] Example 5:

[0083] Referring to Figures 1 and 10, this embodiment differs from Embodiment 1 in that, of the two sets of vertical roll members in each molding unit 12, the upper end of the vertical roll shaft 122 of the vertical roll member furthest from the adjacent molding unit 12 is connected to the corresponding bearing housing via a lifting adjustment mechanism 16, and its lower end is connected to the corresponding bearing housing via a locking pin. On the other hand, the upper end of the vertical roll shaft 122 of the other vertical roll member is connected to the corresponding bearing housing via a locking pin, and its lower end is connected to the corresponding bearing housing via a lifting adjustment mechanism 16. In other words, the two sets of vertical roll members in each molding unit 12 employ a sliding adjustment method that crosses vertically, with the upper end of one vertical roll member connected to the lifting adjustment mechanism 16 and the lower end of the other vertical roll member connected to the lifting adjustment mechanism 16.

[0084] In the roll bending forming apparatus 1 of this embodiment, each vertical roll member can be individually raised and lowered, the adjustment of the flat roll sleeve 121 and the vertical roll sleeve 123 is easier and more flexible, and the size of the forming passage 124 can be flexibly adjusted as required, making it suitable for achieving automation.

[0085] Example 6:

[0086] Referring to Figures 1 and 11, this embodiment differs from Embodiment 1 in that the lower end of each vertical roll shaft 122 is connected to the corresponding bearing housing via a lifting adjustment mechanism 16, and the upper end of each vertical roll shaft 122 is slidably connected to the corresponding bearing housing. Specifically, each bearing housing corresponding to each vertical roll shaft 122 is provided with a sliding groove, the upper end of the vertical roll shaft 122 is inserted into the sliding groove and is slidable within the sliding groove, and the upper end of the vertical roll shaft 122 slidably engages with the corresponding bearing housing, providing a space for movement when the lifting adjustment mechanism 16 raises or lowers the vertical roll shaft 122.

[0087] In the roll bending forming apparatus 1 of this embodiment, the same end of each vertical roll shaft 122 can be adjusted vertically in a synchronous manner, making it suitable for forming open structural steel or closed structural steel of different shapes.

[0088] Example 7:

[0089] Referring to Figures 1 and 12, this embodiment differs from Embodiment 5 in that two sets of flat roll sleeves 121 of flat roll members and two sets of vertical roll sleeves 123 of vertical roll members surround the forming passage 124 adjacent to each other. The two sets of flat roll sleeves 121 are the upper flat roll sleeve and the lower flat roll sleeve, the vertical roll sleeve 123 of the first vertical roll member is the first vertical roll sleeve, and the vertical roll sleeve 123 of the second vertical roll member is the second vertical roll sleeve.

[0090] The tip of the upper flat roll sleeve partially overlaps the rear end of the second vertical roll sleeve in the axial direction of the upper flat roll sleeve, and the overlap width may be X11, with the upper flat roll sleeve positioned above the second vertical roll sleeve. The tip of the second vertical roll sleeve partially overlaps the rear end of the lower flat roll sleeve in the axial direction of the second vertical roll sleeve, and the overlap width may be Y11, with the second vertical roll sleeve positioned on the adjacent molding unit 12 side of the lower flat roll sleeve. The tip of the lower flat roll sleeve partially overlaps the rear end of the first vertical roll sleeve in the axial direction of the lower flat roll sleeve, and the overlap width may be X12, with the lower flat roll sleeve positioned below the first vertical roll sleeve. The tip of the first vertical roll sleeve partially overlaps the rear end of the upper flat roll sleeve in the axial direction of the first vertical roll sleeve, and the overlap width may be Y12, with the first vertical roll sleeve positioned on the side of the upper flat roll sleeve furthest from the adjacent molding unit 12.

[0091] Here, the tip of the upper flat roll sleeve refers to the end closer to the adjacent molding unit 12, and the tip of the lower flat roll sleeve refers to the end further away from the adjacent molding unit 12. The first vertical roll sleeve refers to the vertical roll sleeve 123 on the side further away from the adjacent molding unit 12, and the second vertical roll sleeve refers to the vertical roll sleeve 123 on the side closer to the adjacent molding unit 12. In other words, the two molding units 12 are arranged symmetrically.

[0092] Preferably, each flat roll member includes only one flat roll sleeve 121 or two flat roll sleeves 121, which are arranged along the axial direction of the drive shaft 11. The gap between the two flat roll sleeves 121 is adjustable and may be 0 mm or more. In this embodiment, each flat roll member includes only one flat roll sleeve 121, and of the two flat roll sleeves 121 belonging to the same molding unit 12, one moves axially along the drive shaft 11 in synchronization with the outer sleeve unit 18, and the other moves axially along the drive shaft 11 in synchronization with the inner sleeve unit 17. That is, of the two flat roll sleeves 121, one moves synchronously with the same outer sleeve unit 18 together with one of the two vertical roll sleeves 123, and the other moves synchronously with the same inner sleeve unit 17 together with the remaining vertical roll sleeve 123.

[0093] Furthermore, the flat roll sleeve 121 and the vertical roll shaft 122 are connected via one end of the lifting adjustment mechanism 16, and are movable together in the axial direction of the drive shaft 11. This allows (1) adaptation to forming structural steel with openings or closed openings of different shapes, and (2) control of the deformation dimensions of the forming passage to improve the quality of the formed product. Specifically, if the distance between the two flat roll sleeves 121 is Y1 and the distance between the two vertical roll sleeves 123 is X1, and the first drive member, the second drive mechanism, and the lifting adjustment mechanism 16 are operated to move each vertical roll sleeve 123 and each flat roll sleeve 121 toward the center of the forming passage 124, the dimensional specifications of the forming passage 124 are reduced, i.e., X1 and Y1 become smaller.

[0094] In addition to the advantages of the roll bending apparatus 1 of Example 5, the roll bending apparatus 1 of this embodiment can form a closed forming passage 124 through the cooperation of the vertical roll sleeve 123 and the flat roll sleeve 121, thereby increasing the contact area between the vertical roll sleeve 123 and the flat roll sleeve 121 and the workpiece 4. In particular, when the dimensions of the workpiece 4 are large, the closed forming passage 124 can ensure the forming quality of the workpiece 4. Furthermore, even during the process of reducing the dimensional specifications of the forming passage 124, the closed state can always be maintained, resulting in high flexibility of application and a wide range of applications.

[0095] Example 8:

[0096] Referring to Figures 1 and 13, this embodiment differs from embodiment 7 in that the tip of the upper flat roll sleeve partially overlaps the rear end of the second vertical roll sleeve in the axial direction of the upper flat roll sleeve, and the overlap width may be X21, and the upper flat roll sleeve is located above the second vertical roll sleeve. The tip of the second vertical roll sleeve partially overlaps the rear end of the lower flat roll sleeve in the axial direction of the second vertical roll sleeve, and the overlap width may be Y21, and the second vertical roll sleeve is located on the adjacent molding unit 12 side of the lower flat roll sleeve. The tip of the lower flat roll sleeve partially overlaps the rear end of the first vertical roll sleeve in the axial direction of the lower flat roll sleeve, and the overlap width may be X22, and the lower flat roll sleeve is located below the first vertical roll sleeve. The tip of the first vertical roll sleeve partially overlaps the rear end of the upper flat roll sleeve in the axial direction of the first vertical roll sleeve, and the overlap width may be Y22, and the first vertical roll sleeve is located on the side of the upper flat roll sleeve that is farther from the adjacent molding unit 12.

[0097] Let Y2 be the distance between the two flat roll sleeves 121 and X2 be the distance between the two vertical roll sleeves 123. The first drive member, the second drive mechanism, and the lifting adjustment mechanism 16 operate to move each vertical roll sleeve 123 and each flat roll sleeve 121 away from the center of the forming passage 124, thereby expanding the dimensional specifications of the forming passage 124, i.e., increasing X2 and Y2.

[0098] In the roll bending apparatus 1 of this embodiment, the vertical roll sleeve 123 and the flat roll sleeve 121 cooperate to form a closed forming passage 124, thereby increasing the contact area between the vertical roll sleeve 123 and the flat roll sleeve 121 and the workpiece 4. In particular, when the dimensions of the workpiece 4 are large, the closed forming passage 124 can ensure the forming quality of the workpiece 4. Furthermore, even when the dimensional specifications of the forming passage 124 are increased, the closed state can always be maintained, resulting in high flexibility of application and a wide range of applications.

[0099] Referring to Figures 1 to 13, in some preferred embodiments, the present invention provides a method for adjusting a roll bending forming apparatus 1 according to any of the above embodiments. The method includes the following:

[0100] A step of starting the first drive mechanism 13, operating the first drive mechanism 13 to move the vertical roll member and the flat roll member in the axial direction of the drive shaft 11 and bring them to a predetermined position, thereby adjusting the molding passage 124 to the axial dimension of the drive shaft 11; a step of starting the second drive mechanism, operating the second drive mechanism to raise and lower the vertical roll member and the flat roll member in the axial direction of the vertical roll member and bring them to a predetermined position, thereby adjusting the molding passage to the axial dimension of the vertical roll member, or the A step of adjusting the molding passage 124 to the axial dimension of the vertical roll member by activating the second drive mechanism and the lifting adjustment mechanism 16 and operating them in cooperation to move the vertical roll member and the flat roll member in the axial direction of the vertical roll member and bring them to a predetermined position, or a step of activating the lifting adjustment mechanism 16 and operating the lifting adjustment mechanism 16 to move the vertical roll member in its axial direction and bring it to a predetermined position, thereby adjusting the lifting of the vertical roll member independently and enabling more flexible adjustment.

[0101] The adjustment method of this embodiment is easy to operate, allows for quick and flexible adjustment of the size of the molding passage 124 as required, and can improve production efficiency.

[0102] Referring to Figures 1 to 5 and Figures 14 to 23, in some preferred embodiments, the present invention provides an attachment / detachment device 2 for attaching and detaching a roll bending forming apparatus 1 according to any of the above embodiments. The attachment / detachment device 2 of the present invention will be described in detail below based on the accompanying drawings and specific embodiments, but it should be understood that the attachment / detachment device 2 of the present invention is not limited to the following embodiments.

[0103] Example 1:

[0104] Referring to Figures 1-5, 14-16, and 19-23, the mounting / removal device 2 of this embodiment includes a base 201, a plurality of support slide blocks 202, and a push-pull device 203. The plurality of support slide blocks 202 are slidably mounted on the base 201 and support the inner sleeve unit 17, the outer sleeve unit 18, and the frame bearing unit 3. The number of support slide blocks 202 can be selected as required.

[0105] The cylinder body of the push-pull device 203 is fixedly connected to or pivotally supported by the base 201, and a slide head 204 is provided at the output end of the push-pull device 203, which is slidably connected to the base 201. The slide head 204 is provided with a swing hook 206 which is hooked onto the support slide block 202. The slidable connection of the slide head 204 to the base 201 allows it to act as a guide for movement, improving the operational stability and reliability of the push-pull device 203.

[0106] When the swing hook 206 is connected to the support slide block 202, the push-pull device 203 is activated to move the support slide block 202. A hook 205 is provided on the support slide block 202, and the swing hook 206 can be connected to or disconnected from the hook 205 by reversing its position. In other words, the support slide block 202 is detachably connected to the slide head 204.

[0107] Preferably, there may be multiple push-pull devices 203, and the arrangement positions of the multiple push-pull devices 203 can be set according to requirements. More preferably, there may be four push-pull devices 203, each capable of adapting to the different stroke requirements of the movement position of the member to be removed. For example, if the stroke position is close to the center of the drive shaft 11, the member to be removed can be moved by the push-pull device 203 located near the center of the drive shaft 11, and if the stroke position is close to the end of the drive shaft 11, the member to be removed can be moved by the push-pull devices 203 located near both ends of the drive shaft 11. This arrangement reduces the stroke requirements of the push-pull devices, reduces the space occupied in the workshop, facilitates installation and removal, and improves efficiency.

[0108] Preferably, the mounting / removal device 2 may further include a drive shaft support block, which is mounted on the base 201 and supports the drive shaft 11. Furthermore, the drive shaft support block is slidable along the axial direction of the drive shaft 11 and can support the drive shaft 11 at different positions as required.

[0109] Preferably, the support slide block 202 is provided with a jack 207, which operates to move up and down, contacting and supporting the corresponding inner sleeve unit 17, outer sleeve unit 18, and frame bearing unit 3. The jack 207 allows the height positions of the inner sleeve unit 17, outer sleeve unit 18, and frame bearing unit 3 to be adjusted, thereby ensuring sufficient contact between the support slide block 202 and the inner sleeve unit 17, outer sleeve unit 18, and the frame bearing housing 31 of the frame bearing unit 3, thereby ensuring stability and reliability of the support.

[0110] Furthermore, each of the support slide blocks 202 is provided corresponding to the first bearing housing 172, the second bearing housing 182, and the frame bearing housing 31, that is, the support slide blocks 202 support the first bearing housing 172, the second bearing housing 182, and the frame bearing housing 31, and the jack 207 acts on them. The first bearing housing 172, the second bearing housing 182, and the frame bearing housing 31 may be directly mounted on the support slide block 202 and move together with the support slide block 202 by their own weight, or they may be connected to the support slide block 202 via a connecting member and move together with the support slide block 202.

[0111] Here, the support slide block 202 may be moved in correspondence with the first bearing housing 172, the second bearing housing 182, and the frame bearing housing 31, respectively, or it may be moved in correspondence with the first bearing housing 172, and the first bearing housing 172, the second bearing housing 182, and the frame bearing housing 31 may be moved as a single unit.

[0112] Specifically, the push-pull device 203 includes two first push-pull devices 203 and two second push-pull devices 203, with the two second push-pull devices 203 positioned between the two first push-pull devices 203. The second push-pull devices 203 are equipped with displacement sensors that can measure the displacement of the support slide block 202 as it is driven to move by the second push-pull devices 203.

[0113] Preferably, the shape of the portion of the support slide block 202 that engages with the corresponding bearing housing conforms to the shape of the corresponding bearing housing, and the shape of the portion of the support slide block 202 that engages with the corresponding bearing housing can be flexibly set. Specifically, the shape of the support slide block 202 corresponding to the second bearing housing 182 conforms to the shape of the second bearing housing 182, the shape of the support slide block 202 corresponding to the first bearing housing 172 conforms to the shape of the first bearing housing 172, and the shape of the support slide block 202 corresponding to the frame bearing housing 31 conforms to the shape of the frame bearing housing 31. In this embodiment, the shape of the portion of the support slide block 202 that engages with the corresponding bearing housing is rectangular.

[0114] Preferably, the mounting / removal device 2 further includes a lifting mechanism, which is used to lift the vertical roll member. The lifting mechanism includes a vertical roll frame 208, which is provided with lifting lugs 209 and mounting holes 210 corresponding to the vertical roll member. Furthermore, the lifting lugs 209 can be connected to a lifting hook 211 of a factory crane via a lifting rope 212. The mounting hole 210 includes a mounting portion 2101 and a lifting portion 2102, wherein the diameter D1 of the lifting portion 2102 is smaller than the diameter D2 of the mounting portion 2101, the diameter D2 of the mounting portion 2101 is larger than the maximum diameter of the vertical roll sleeve 123, and the diameter D1 of the lifting portion 2102 is smaller than the maximum diameter of the vertical roll sleeve 123. This prevents the vertical roll member from falling off the lifting portion 2102 during the lifting process.

[0115] The vertical roll frame 208 is moved above the vertical roll member, aligning the center of the vertical roll member with the center of the mounting portion 2101. The vertical roll frame 208 is lowered so that the upper end of the vertical roll member passes through the mounting portion 2101 and the maximum diameter portion of the vertical roll sleeve 123 is positioned above the mounting portion 2101. Then, the vertical roll frame 208 is moved in parallel to move the vertical roll member into the lifting portion 2102. This prevents the vertical roll sleeve 123 from detaching from the lifting portion 2102 due to the maximum diameter portion of the vertical roll sleeve 123. Then, the vertical roll member is lifted to a predetermined position by moving the vertical roll frame 208.

[0116] The mounting / removal device 2 described above has a simple structure and is easy to install and remove. With the assistance of this device 2, the vertical roll members, flat roll members, inner sleeve unit 17, outer sleeve unit 18, and other parts of the roll bending forming machine 1 can be quickly assembled, removed, replaced, and adjusted, enabling the installation, removal, and replacement of the roll bending forming machine 1 to be completed quickly. This makes it possible to handle the production of workpieces 4 of different shapes and specifications and workpieces 4 of different sizes, improving product quality, reducing replacement time, and increasing production efficiency. It also contributes to cost reduction by reducing the stockpiling of spare parts for production.

[0117] Example 2:

[0118] Referring to Figure 17, this embodiment differs from Embodiment 1 in that the shape of the portion where the support slide block 202 engages with the corresponding bearing housing is trapezoidal.

[0119] The mounting / removal device 2 of this embodiment can be adapted to support engagement with a trapezoidal bearing housing, thereby improving the stability and reliability of the support.

[0120] Example 3:

[0121] Referring to Figure 18, this embodiment differs from Embodiment 1 in that the shape of the portion where the support slide block 202 engages with the corresponding bearing housing is arc-shaped.

[0122] The mounting / removal device 2 of this embodiment can be adapted to support engagement with an arc-shaped bearing housing, thereby improving the stability and reliability of the support.

[0123] Referring to Figures 1 to 4, 14 to 16, and 19 to 22, in some preferred embodiments, the present invention provides a method for attaching and detaching a roll bending forming apparatus 1 according to any of the above embodiments. This method is carried out by an attachment / detachment apparatus 2 according to any of the above embodiments and includes the following.

[0124] The connection between the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 and the corresponding drive shaft 11 is disconnected, and the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are moved in the axial direction of the drive shaft 11, sliding away from the end of the drive shaft 11 and detached from the drive shaft 11. This enables maintenance and replacement using a lifting mechanism. Specifically, by removing the limit end caps attached to both ends of the drive shaft 11 from the drive shaft 11, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 can slide away from the end of the drive shaft 11.

[0125] 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 drive shaft 11, and by connecting them to each other, the frame bearing unit 3, the outer sleeve unit 18, and the inner sleeve unit 17 can be moved as a single unit.

[0126] The push-pull device 203 is activated to move the frame bearing unit 3, inner sleeve unit 17, and outer sleeve unit 18 together in the axial direction of the drive shaft 11, detaching them from the drive shaft 11 and bringing them to a first pre-set position. After reaching the first pre-set position, the connection between the frame bearing unit 3 and the outer sleeve unit 18 is disconnected, thereby preventing the frame bearing unit 3 from moving together with the outer sleeve unit 18. Alternatively, the frame bearing unit 3 may be fixed and held in the first pre-set position to prevent it from being dragged and moving when the outer sleeve unit 18 moves.

[0127] Specifically, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are connected to each other, and the support slide block 202 is supported at the bottom of the first bearing housing 172 of the inner sleeve unit 17. The first bearing housing 172 is directly mounted on the support slide block 202 and is further fixed to the support slide block 202 via a locking mechanism to prevent the first bearing housing 172 from detaching from the support slide block 202 during movement. The swing hook 206 of the push-pull device 203 is reversed and hooked onto the hook 205 on the support slide block 202, and the push-pull device 203 is operated to move the support slide block 202 corresponding to the inner sleeve unit 17 by a stroke A2. That is, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are moved from the initial position to the first pre-set position. When the first pre-set position is reached, the frame bearing unit 3, the inner sleeve unit 17, and the outer sleeve unit 18 are all detached from the drive shaft 11. In the initial position, the distance between the frame bearing housings 31 is A1.

[0128] Here, the support slide block 202 may be supported and connected to the second bearing housing 182 or the frame bearing housing 31. During the removal process, by supporting and connecting the support slide block 202 to the first bearing housing 172 near the end, frequent operation of the swing hook 206 can be avoided, and removal efficiency can be improved.

[0129] The push-pull device 203 is activated to move the outer sleeve unit 18 and the inner sleeve unit 17 together in the axial direction of the drive shaft 11, away from the drive shaft 11, to reach a second pre-set position. After reaching the second pre-set position, the connection between the outer sleeve unit 18 and the inner sleeve unit 17 is disconnected, thereby preventing the outer sleeve unit 18 from moving together with the inner sleeve unit 17. Alternatively, the outer sleeve unit 18 may be fixed and held in the second pre-set position to prevent it from being dragged and moving when the inner sleeve unit 17 moves.

[0130] Specifically, the outer sleeve unit 18 and the inner sleeve unit 17 are connected, the swing hook 206 of the push-pull device 203 is reversed, and it is hooked onto the hook 205 of the support slide block 202. By operating the push-pull device 203, the support slide block 202 corresponding to the inner sleeve unit 17 is moved by a stroke A3, and the inner sleeve unit 17 and the outer sleeve unit 18 are moved from the first pre-set position to the second pre-set position. When they reach the second pre-set position, both the inner sleeve unit 17 and the outer sleeve unit 18 are completely detached from the frame bearing unit 3.

[0131] Furthermore, the push-pull device 203 is activated to move the inner sleeve unit 17 in the axial direction of the drive shaft 11 away from the drive shaft 11, reaching a third pre-set position. Here, the first pre-set position, the second pre-set position, and the third pre-set position are, in order, positions away from the end of the drive shaft 11. Specifically, the swing hook 206 of the push-pull device 203 is reversed and hooked onto the hook 205 of the support slide block 202, moving the support slide block 202 corresponding to the first bearing housing 172 of the inner sleeve unit 17 by a stroke A4. As a result, the inner sleeve unit 17 moves from the second pre-set position to the third pre-set position, and when it reaches the third pre-set position, the inner sleeve unit 17 is completely detached from the outer sleeve unit 18, and removal is completed.

[0132] After removal is complete, the corresponding vertical roll member and flat roll member can be replaced. After replacing the vertical roll member and flat roll member, the inner sleeve unit 17, the outer sleeve unit 18, and the frame bearing housing 31 can be installed in the reverse order of removal.
