Description

Technical Field

[0001] The present invention belongs to the technical field of metallurgical equipment and relates to an assembled vertical and horizontal roll double-stream forming device. Background Art

[0002] At present, for the cold forming single-stream production of structural steel, the equipment for adjusting the pressure at the position of the forming roll or the pressure roll is relatively simple. It is adjusted manually or mechanically and cannot be detected and automatically controlled online, resulting in poor quality and low production efficiency and benefits. Hot bending forming is to directly utilize the post-rolling waste heat to roll and form the slab after rolling to produce structural steel.

[0003] In the prior art, in order to enable the same forming device to produce structural steel of different specifications, it is necessary to adjust the positions of the vertical roll and the horizontal roll of the forming machine. However, in the prior art, whether it is a cold bending forming or a hot bending forming device, the position of the forming roll on the roll press is not convenient to adjust. For a vertical and horizontal roll double-stream forming machine, the adjustment difficulty is even greater. In order to realize the adjustment of the positions of the vertical roll and the horizontal roll of the forming machine, the Chinese patent with the publication number CN113634633A discloses a double-stream roll pressing forming device for structural steel, which includes a frame and two forming units arranged side by side on the frame. Each forming unit includes an upper roll assembly, a lower roll assembly and a vertical roll assembly. The upper roll assembly and the lower roll assembly are respectively located above and below the section steel channel, and the two groups of vertical roll assemblies are respectively located on the left and right sides of the section steel channel. A lifting oil cylinder and a horizontal pushing oil cylinder are arranged on the frame. The lifting oil cylinder is used to adjust the distance between the upper roll assembly and the lower roll assembly; the horizontal pushing oil cylinder is used to adjust the distance between the two groups of vertical roll assemblies. The adjacent two groups of vertical roll assemblies of the two forming units are driven by the same group of the horizontal pushing oil cylinders, and the horizontal pushing oil cylinder is a two-way oil cylinder. This device is convenient to adjust the section steel channel size through the oil cylinder to adapt to the forming of structural steel of different specifications. However, the size of the section steel channel adjusted by the oil cylinder is always limited by the frame and cannot enable the same device to produce structural steel of different shapes or with a large difference in specifications. However, in order to enable the same device to produce structural steel of different shapes or with a large difference in specifications, it is necessary to replace the vertical roll and / or the horizontal roll of the forming machine. However, at present, the replacement of the forming roll on the forming machine is quite complicated, which is extremely likely to result in a large number of production spare parts and low replacement efficiency, leading to a slow production progress. For the existing vertical and horizontal roll double-stream forming machine, the complexity of replacing the forming roll will only be greater.

[0004] Therefore, in order to overcome this defect, an assembled vertical and horizontal roll double-stream forming device is designed, which adopts a standard module assembled structure. When replacing the forming roll, only the assembled unit of different specifications needs to be replaced to adapt to structural steel of different shapes or with a large difference, and it is convenient for the rapid replacement of the forming roll and the adjustment of processing and assembly to improve the overall production efficiency. Summary of the Invention

When replacing the forming roll, only the assembled unit of different specifications needs to be replaced, and the replacement parts are in the form of a box to adapt to structural steel of different shapes or with large differences, and it is convenient for the rapid replacement of the forming roll and the adjustment of processing and assembly, so as to improve the overall production efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An assembled flat and vertical roll double-flow forming device includes an upper roll assembly, a lower roll assembly, a vertical roll assembly and a tie rod device. The upper roll assembly, the lower roll assembly and the vertical roll assembly are combined to form two profiled steel channels arranged side by side between the upper roll assembly and the lower roll assembly. The vertical roll assembly includes side vertical roll assemblies located on both sides of the profiled steel channels and a double vertical roll assembly located between the two profiled steel channels. The tie rod device respectively penetrates and connects the two side vertical roll assemblies and the double vertical roll assembly between the upper roll assembly and the lower roll assembly to realize the installation of the upper roll assembly, the lower roll assembly and the vertical roll assembly.

[0008] Further, the upper roll assembly includes an upper box body, an upper transmission shaft rotatably connected in the upper box body, and two upper roll sleeves connected to the upper transmission shaft, and the upper box body is provided with through holes for the tie rod device to penetrate.

[0009] Further, the upper roll assembly further includes a flat roll bearing seat, a flat roll bearing and a lifting device. The flat roll bearing in the upper roll assembly is sleeved on the upper transmission shaft, the flat roll bearing seat is used for installing the flat roll bearing, and one end of the lifting device is connected to the upper box body, and the other end is connected to the flat roll bearing seat to drive the upper transmission shaft to move up and down.

[0010] Further, the lower roll assembly includes a lower box body, a lower transmission shaft rotatably connected in the lower box body, and two lower roll sleeves connected to the lower transmission shaft, and the lower box body is provided with through holes for the tie rod device to penetrate.

[0011] Further, the lower roll assembly further includes a flat roll bearing seat, a flat roll bearing and a lifting device. The flat roll bearing in the lower roll assembly is sleeved on the lower transmission shaft, the flat roll bearing seat is used for installing the flat roll bearing, and one end of the lifting device is connected to the lower box body, and the other end is connected to the flat roll bearing seat to drive the lower transmission shaft to move up and down.

[0012] Further, the side vertical roll assembly includes a side box body, a vertical roll shaft rotatably connected in the side box body, and a vertical roll sleeve connected to the vertical roll shaft, and a through hole for the pull rod device to penetrate is provided on the side box body.

[0013] Further, the double vertical roll assembly includes a double roll box body, two vertical roll shafts rotatably connected in the double roll box body, and a vertical roll sleeve connected to the vertical roll shaft, and a through hole for the pull rod device to penetrate is provided on the double roll box body.

[0014] Further, the side vertical roll assembly further includes a horizontal push oil cylinder arranged on the side box body for driving the vertical roll shaft to move left and right, and the double vertical roll assembly includes a two-way horizontal push oil cylinder arranged on the double roll box body for driving the two vertical roll shafts in the double vertical roll assembly to move left and right respectively.

[0018] A prefabricated horizontal and vertical roll double-stream forming device provided by the present invention has a compact structural layout. It adopts a standard module prefabricated structure and does not need to rely on a frame as a support. The upper roll assembly, the vertical roll assembly and the lower roll assembly are assembled through a pull rod device to form a prefabricated horizontal and vertical roll double-stream forming machine. When replacing the forming roll, only the overall assembly of different specifications needs to be replaced, and the replacement parts are in the form of a box body to adapt to structural steel of different shapes or with large differences, and it is convenient for the rapid replacement of the forming roll and the adjustment of processing and assembly, so as to improve the overall production efficiency. Moreover, a single prefabricated horizontal and vertical roll double-stream forming machine or a combination of multiple prefabricated horizontal and vertical roll double-stream forming machines can be adopted. When multiple prefabricated horizontal and vertical roll double-stream forming machines are combined, the distance between the prefabricated horizontal and vertical roll double-stream forming machines is reduced, and heat loss is reduced during waste heat forming. The single prefabricated horizontal and vertical roll double-stream forming machine or multiple prefabricated horizontal and vertical roll double-stream forming machines can be quickly replaced to improve production efficiency. Since the size of the profiled steel channel can be adjusted online through a lifting device and a horizontal push oil cylinder, the problem of replacing the overall frame every time a certain specification of profiled steel is produced is avoided, and the number of production operation replacement parts is reduced.

[0034] Please refer toFigures 1 to 4 It is an assembled horizontal and vertical roll double-stream forming device, including an upper roll assembly 10, a lower roll assembly 20, a vertical roll assembly and a tie rod device 60. The upper roll assembly 10, the lower roll assembly 20 and the vertical roll assembly are combined to form two steel section channels arranged side by side between the upper roll assembly 10 and the lower roll assembly 20. The vertical roll assembly includes side vertical roll assemblies 30 located on both sides of the steel section channels and a double vertical roll assembly 40 located between the two steel section channels.

And the lower box body 21 is provided with through holes for the tie rod device 60 to penetrate. The side vertical roll assembly 30 includes a side box body 31, a vertical roll shaft rotatably connected in the side box body 31 and a vertical roll sleeve connected to the vertical roll shaft. And the side box body 31 is provided with through holes for the tie rod device 60 to penetrate. The double vertical roll assembly 40 includes a double roll box body 41, two vertical roll shafts rotatably connected in the double roll box body 41 and vertical roll sleeves connected to the vertical roll shafts. And the double roll box body 41 is provided with through holes for the tie rod device 60 to penetrate.

[0036] The tie rod device 60 includes a tie rod bolt 61 that penetrates the upper roll assembly 10, the lower roll assembly 20 and the vertical roll assembly and a tie rod nut 62 that cooperates with the tie rod bolt 61. The tie rod bolt 61 penetrates through the through holes provided on the upper roll assembly 10, the lower roll assembly 20 and the vertical roll assembly to assemble the upper roll assembly 10, the lower roll assembly 20 and the vertical roll assembly together. Then, by cooperating with the tie rod nut 62 to lock the tie rod bolt 61, the installation of the assembled horizontal and vertical roll double-stream forming device can be completed, forming a complete assembled horizontal and vertical roll double-stream forming machine. Without relying on the connection of a frame, the assembly can be completed. The entire assembled horizontal and vertical roll double-stream forming machine only includes five major modules: the upper roll assembly 10, the lower roll assembly 20, two side vertical roll assemblies 30 and the double vertical roll assembly 40, forming a standard modular assembled structure, which is convenient for overall and rapid replacement to adapt to structural steel with different shapes or large differences in specifications.

[0037] The pull rod device 60 is at least in four groups and is respectively arranged at both ends of the upper roll assembly 10 to ensure the connection stability among the upper roll assembly 10, the lower roll assembly 20 and the vertical roll assembly (at this time, the double vertical roll assembly 40 is not installed or the force on the double vertical roll assembly 40 is small, and the double vertical roll assembly 40 can be fixed through the interaction force between the double vertical roll box body 41 and the upper box body 11 and the lower box body 21). Specifically, please refer to Figure 3 In this embodiment, the pull rod device 60 is in eight groups, four of which are respectively located at both ends of the upper roll assembly 10 for realizing the connection between the upper roll assembly 10 and the lower roll assembly 20 and the two side vertical roll assemblies 30, and the remaining four groups are located in the middle of the upper roll assembly 10 for realizing the connection between the upper roll assembly 10 and the lower roll assembly 20 and the double vertical roll assembly 40.

[0038] Among them, the torque is transmitted between the upper transmission shaft 12 and the upper roll sleeve 17 in the upper roll assembly 10 through key or tooth fit for synchronous rotation. One end of the upper transmission shaft 12 can access power through a transmission structure. For example, a motor transmits power to the upper transmission shaft 12 through transmission devices such as a speed reducer, a transmission shaft, and a coupling. The structure of the lower roll assembly 20 is similar to that of the upper roll assembly 10. The torque is transmitted between the vertical roll sleeve 33 and the vertical roll shaft 34 through key or tooth fit for synchronous rotation. Power is accessed on the vertical roll shaft 34 through a transmission structure. For example, a motor transmits power to the vertical roll shaft 34 through transmission devices such as a speed reducer, a transmission shaft, and a coupling. Of course, power can also not be set, and it rotates driven by the structural steel.

[0039] In this embodiment, the upper roll assembly 10 further includes a flat roll bearing seat 14, a flat roll bearing 13 and a lifting device 15. The flat roll bearing 13 in the upper roll assembly 10 is sleeved on the upper transmission shaft 12. The flat roll bearing seat 14 is used for installing the flat roll bearing 13. One end of the lifting device 15 is connected to the upper box body 11, and the other end is connected to the flat roll bearing seat 14 to drive the upper transmission shaft 12 to move up and down. The structure of the lower roll assembly 20 is similar to that of the upper roll assembly 10, and also includes a flat roll bearing seat 14, a flat roll bearing 13 and a lifting device 15. The flat roll bearing 13 in the lower roll assembly 20 is sleeved on the lower transmission shaft 22. The flat roll bearing seat 14 is used for installing the flat roll bearing 13. One end of the lifting device 15 is connected to the lower box body 21, and the other end is connected to the flat roll bearing seat 14 to drive the lower transmission shaft 22 to move up and down.

[0040] The side vertical roll assembly 30 further includes a horizontal push oil cylinder 37 arranged on the side box body 31 for driving the vertical roll shaft to move left and right. The double vertical roll assembly 40 includes a two-way horizontal push oil cylinder 42 arranged on the double roll box body 41 for driving the two vertical roll shafts in the double vertical roll assembly 40 to move left and right respectively.

[0041] Specifically, the side vertical roll assembly 30 and the double vertical roll assembly 40 further include a vertical roll shaft bearing 32 sleeved on the vertical roll shaft 34, a vertical roll shaft bearing seat (not shown) for mounting the vertical roll shaft bearing 32, and a seal for the bearing. One end of the transverse push oil cylinder 37 and the double-direction transverse push oil cylinder 42 away from the side box body 31 or the double roll box body 41 is connected to the vertical roll shaft bearing seat (not shown) to achieve the purpose of driving the vertical roll shaft to move left and right or driving the two vertical roll shafts in the double vertical roll assembly 40 to move left and right respectively. The structures of the transverse push oil cylinder 37 and the double-direction transverse push oil cylinder 42 are recorded in the Chinese patent with the publication number CN113634633A. The difference is that in this embodiment, the transverse push oil cylinder 37 and the double-direction transverse push oil cylinder 42 are distributed on the side box body 31 and the double roll box body 41.

[0042] The lifting device 15 is the lifting oil cylinder disclosed in the Chinese patent with the publication number CN113634633A. The difference is that in this embodiment, the lifting device 15 is arranged on the upper box body 11 and / or the lower box body 21.

[0043] In this embodiment, a push-pull hook 24 is further provided on one side of the lower box body 21. The push-pull hook 24 is used to translate the assembled flat and vertical roll double-flow forming device as a whole to adapt to rapid overall replacement. Three flat roll bearing seats 14 are provided in both the upper roll assembly 10 and the lower roll assembly 20 to ensure the stability of the upper transmission shaft 12 and the lower transmission shaft 22.

[0044] In this embodiment, the relative assembly positions of the key components are the center distance A1 of the flat roll sleeves (the center distance between the two upper roll sleeves 17 is A1, and the center distance between the two lower roll sleeves 23 is A1), the center distance A2 of the flat roll bearing seats 14 (that is, the center distance between the two flat roll bearing seats 14 in the upper roll assembly 10 is A2), the center distance B1 between the two vertical roll sleeves in one section steel channel, the center distance B2 between the two vertical roll sleeves in the double vertical roll assembly 40, the center distance C1 between the upper transmission shaft 12 and the lower transmission shaft 22, and the height C2 of the vertical roll box body. Positioning keys 36 are provided at the joints between the side vertical roll assembly 30 or the double vertical roll assembly 40 and the upper roll assembly 10 and the lower roll assembly 20, and adjustment pads 35 can be provided at the joints as needed to ensure the accuracy of positioning and the stability of connection.

[0045] Embodiment 2

[0046] Please refer to Figure 5, The difference between this embodiment and Embodiment 1 is that in this embodiment, the double-sided flat and vertical roll double-stream forming device does not include the double vertical roll assembly 40, and the side vertical roll assembly 30 only includes the side box body 31, thus forming a double-sided flat and vertical roll double-stream forming device with only the complete upper roll assembly 10 and lower roll assembly 20, which can be used as a double-stream upper and lower guide device.

[0047] Embodiment 3

[0048] Please refer to Figure 6 , The difference between this embodiment and Embodiment 1 is that in this embodiment, the upper roll assembly 10 and the lower roll assembly 20 in the double-sided flat and vertical roll double-stream forming device only include the upper box body 11 and the lower box body 21 as assembly components, thus forming a double-sided flat and vertical roll double-stream forming device with only the complete side roll assembly and double vertical roll assembly 40, which can be used as a double-stream left and right guide device.

[0049] Embodiment 4

[0050] Please refer to Figures 7 to 8 , In this embodiment, the double-sided flat and vertical roll double-stream forming device includes multiple double-sided flat and vertical roll double-stream forming machines in Embodiment 1 arranged in series along the slab forming and conveying direction. The tops of adjacent double-sided flat and vertical roll double-stream forming machines are detachably connected by a frame connection turning hook 80, and the bottoms are press-connected to the installation track 90 through a spring cylinder device 70, which not only realizes the compact connection of adjacent double-sided flat and vertical roll double-stream forming machines but also realizes the fixation of the double-sided flat and vertical roll double-stream forming device to the installation track 90. Each double-sided flat and vertical roll double-stream forming machine is installed on the installation track 90, and the double-sided flat and vertical roll double-stream forming machines can be arranged compactly or at a certain distance from each other. When multiple double-sided flat and vertical roll double-stream forming machines are combined, the distance between the double-sided flat and vertical roll double-stream forming machines is reduced, and heat loss can be reduced during waste heat forming.

[0051] Embodiment 5

[0052] The difference between this embodiment and Embodiment 1 is that in this embodiment, the tie rod device 60 includes a hydraulic bolt passing through the upper roll assembly 10, the lower roll assembly 20, and the vertical roll assembly and a hydraulic nut cooperating with the tie rod bolt 61.

[0053] Embodiment 6

[0054] The difference between this embodiment and Embodiment 1 is that in this embodiment, the lifting device 15 in the upper roll assembly 10 is a structure of a lead screw cooperating with a nut. One end of the lead screw is connected to the flat roll bearing seat 14, and the other end is connected to the upper box body 11 through a nut. By rotating the nut, the up and down position of the upper transmission shaft 12 can be adjusted. The lifting device 15 in the lower roll assembly 20 has the same structure as the lifting device 15 in the upper roll assembly 10.

[0055] The present invention can be used in the production and processing equipment for hot-rolled wide and thick steel plates or coils (with a thickness of 5 mm to 50 mm, a width of 1000 mm to 5400 mm, and a temperature of 500 to 1000 °C), which can directly perform hot roll bending forming on the steel for structural use after hot edge cutting or profiling, especially applicable to the high-strength waste heat forming heavy structural steel for hot-rolled strip.

[0056] The assembled horizontal and vertical roll double-stream forming machine of the present invention can be used for double-stream production of section steel. Its structural layout is compact. It adopts a standard modular assembled structure and does not rely on the frame as a support. The upper roll assembly 10, the vertical roll assembly, and the lower roll assembly 20 are assembled through the tie rod device 60 to form the assembled horizontal and vertical roll double-stream forming machine. When replacing the forming rolls, only the assembled units of different specifications need to be replaced, and the replacement parts are in the form of boxes to adapt to different shapes or section steels with large differences in structure, and it is convenient for quick replacement of the forming rolls to improve the overall production efficiency. Moreover, a single assembled horizontal and vertical roll double-stream forming machine or a combination of multiple assembled horizontal and vertical roll double-stream forming machines can be adopted. When multiple assembled horizontal and vertical roll double-stream forming machines are combined, the spacing between the assembled horizontal and vertical roll double-stream forming machines is reduced, and heat loss is reduced during waste heat forming. The single assembled horizontal and vertical roll double-stream forming machine or multiple assembled horizontal and vertical roll double-stream forming machines can be quickly replaced. The adjustment rate of processing and assembly and the production efficiency are improved. Since the size of the section steel channel can be adjusted online through the lifting device 15 and the transverse push oil cylinder 37, the problem of replacing the overall frame every time a new specification of section steel is produced is avoided, and the number of replacement parts in production operations is reduced.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
