Description

Technical Field

[0001] The present invention belongs to the technical field of steel processing, and specifically relates to a stainless steel bending device. Background Art

[0002] Stainless steel bending devices are machinery specifically used for bending stainless steel pipes, plates, etc. These devices usually adopt mechanical transmission and control systems, and can achieve fast and accurate bending operations. They are widely used in fields such as pipeline installation, decoration, and industrial manufacturing. There are various types of stainless steel bending devices, including but not limited to stainless steel pipe bending machines, stainless steel plate bending machines, numerical control bending machines, etc. They differ in structural design, control accuracy, automation level, etc. to meet different processing requirements and improve production efficiency.

[0003] A Chinese patent with the publication number CN118080639A discloses a U-shaped steel bending device, which includes a moving roller group and two fixed roller groups. The steel workpiece passes through between the moving roller group and the two fixed roller groups to form a bending arc. The moving roller group includes a functional support roller, a bottom support roller, and two side support rollers that form a walking channel for the steel workpiece. The functional support roller realizes the support inside the U-shaped groove during the two-way bending of the steel workpiece through an installed functional component. The functional component includes a support wheel for side plate support and a support sleeve for bottom plate support, which can realize the left and right bending of the U-shaped steel relative to the side plate and the up and down bending relative to the bottom plate to meet different bending requirements. When performing bending in different directions, different functional components can be selected and matched on the functional support roller to maintain the effective support of the U-shaped steel at the bending point and reduce the deformation of the U-shaped steel during bending.

[0004] Currently, in the prior art, when bending stainless steel, the bending is basically achieved by stretch bending. When the pulling roller contacts the surface of the stainless steel during the stretch bending process and the friction between the pulling roller and the stainless steel is too large, it is extremely easy for the surface of the stainless steel to appear wrinkles and scratches when being pulled out, which has a negative impact on the performance and appearance of the material.

[0005] Therefore, the present invention provides a stainless steel bending device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A stainless steel bending device of the present invention includes a housing. In the middle of the inner wall of the housing, a power box is fixedly installed. On both sides of the power box, a steel outlet roller shaft and a steel inlet roller shaft are symmetrically and rotatably connected. On both sides of the power box, pressing steel roller shafts are symmetrically arranged. The pressing steel roller shafts are arranged directly above the middle of the steel outlet roller shaft and the steel inlet roller shaft. At one end on both sides of the power box, material inlet plate openings are provided. On both sides of the power box, angle adjustment motors are fixedly installed. The output ends of the two angle adjustment motors are fixedly installed with steel receiving blocks. The two steel receiving blocks are respectively placed directly below the two pressing steel roller shafts. Through grooves adapted to the material inlet plate openings are provided on the surface of the housing. Inside the steel inlet roller shaft, a lower spraying assembly is provided. The lower spraying assembly is used for spraying lubricating oil on the lower surface of the stainless steel. Inside the pressing steel roller shaft, an upper spraying assembly is provided. The upper spraying assembly is used for spraying lubricating oil on the upper surface of the stainless steel;

[0008] The stainless steel material to be bent is placed into the housing through the material inlet plate opening. The steel inlet roller shaft in the housing drives the stainless steel material to move forward. While moving, the lower spraying assembly in the steel inlet roller shaft sprays lubricating oil on the lower surface of the stainless steel. Subsequently, through the rotation of the steel inlet roller shaft, one end of the stainless steel is placed on the steel outlet roller shaft. The stainless steel will be placed between the steel inlet roller shaft and the power box. Subsequently, by controlling the angle adjustment motor to drive the steel receiving block to move. When the steel receiving block moves to a certain position, the angle formed between the steel receiving block, the steel outlet roller shaft, and the steel inlet roller shaft at this time is the angle at which the stainless steel material needs to be bent. Subsequently, control the pressing steel roller shaft to move downward. When the pressing steel roller shaft contacts the stainless steel material, the upper spraying assembly in the pressing steel roller shaft sprays lubricating oil on the upper surface of the stainless steel. Subsequently, control the pressing steel roller shaft to continue moving downward. During the downward movement, the pressing steel roller shaft squeezes the steel body of the stainless steel material and moves it towards the steel receiving block. When the lower surface of the stainless steel material contacts the top of the steel receiving block, stop moving the pressing steel roller shaft. Subsequently, continue to drive the steel inlet roller shaft and the steel outlet roller shaft to rotate. When the two rotate, they drive the remaining stainless steel material to move into the housing. Subsequently, through the limiting and squeezing force of the pressing steel roller shaft, the stainless steel material will be bent to the specified angle, thereby realizing the bending operation of the stainless steel material. When the stainless steel material moves in the housing, the upper spraying assembly in the pressing steel roller shaft sprays lubricating oil on the upper surface of the stainless steel material, reducing the friction between the pressing steel roller shaft and the upper surface of the stainless steel material. The lower spraying assembly in the steel inlet roller shaft sprays lubricating oil on the lower surface of the stainless steel material, reducing the friction between the stainless steel material and the steel receiving block. Through the cooperation of the two, the friction during the bending of the stainless steel material is reduced, and pulling and deformation are avoided.

[0009] Preferably, a driving wheel motor is fixedly installed in the middle of the inner wall of the power box. The output ends of the driving wheel motor are symmetrically and fixedly installed with driving wheels. The inner wall of the power box is symmetrically and rotatably connected with two groups of transmission wheels. The teeth on the two groups of transmission wheels are respectively meshed with the teeth on the two driving wheels. One side of the two groups of transmission wheels is respectively fixedly connected with one end of the two steel outlet rollers and the steel inlet rollers. The driving wheel motor drives the driving wheels to rotate. When the driving wheels rotate, they drive the transmission wheels to rotate through tooth engagement, thereby driving the steel inlet rollers and the steel outlet rollers to rotate, realizing the pulling of the stainless steel. By pulling and bending the stainless steel, this device can be applied to stainless steel of different lengths. By controlling the operation of the driving wheel motor, the rotation and stop of the steel outlet rollers and the steel inlet rollers can be realized. Since this device is symmetrically provided with two working stations, the bending efficiency of the stainless steel can be increased during the bending operation, which is more conducive to the operation.

[0010] Preferably, a hydraulic cylinder is fixedly installed on the top of the power box. The output end of the hydraulic cylinder is fixedly installed with a connecting frame. The two ends of the connecting frame are respectively rotatably connected with one side of the two steel pressing rollers. The two ends of the connecting frame are slidably connected with the inner wall of the power box. By controlling the hydraulic cylinder to drive the connecting frame to move, the position movement of the steel pressing rollers can be realized, so that when the stainless steel is placed between the steel inlet rollers and the steel outlet rollers, the steel pressing rollers can squeeze the stainless steel for bending operation. By squeezing and bending the stainless steel with the steel pressing rollers, this device can be applied to stainless steel of different thicknesses.

[0011] Preferably, a telescopic cylinder is fixedly installed at the bottom of the power box. The output ends of the telescopic cylinder are symmetrically and fixedly installed with baffles. Two groups of sliding rods are symmetrically and fixedly installed on the inner wall of the shell. One end of the two groups of sliding rods is respectively rotatably connected with the inner walls of the two steel outlet rollers and the steel inlet rollers. One side of each of the two baffles is fixedly installed with a limiting block. Both limiting blocks are slidably connected with the outer wall of the shell. The two groups of sliding rods are respectively slidably connected with the inner walls of the two baffles. When the stainless steel is placed into the shell, by controlling the telescopic cylinder to drive the sliding rods to move, the limiting blocks slide on the outer wall of the shell. When the sliding rods and the limiting blocks contact one side of the stainless steel, stop the telescopic cylinder from moving the sliding rods. At this time, the sliding rods perform a limiting block on the stainless steel, preventing the stainless steel from running out between the steel outlet rollers and the steel inlet rollers due to excessive extrusion force of the steel pressing rollers during bending. At the same time, by using the sliding rods to perform a limiting block on the stainless steel, this device can also be applied to stainless steel of different widths.

[0012] Preferably, the lower spraying assembly includes an oil storage box which is placed inside the inner wall of the steel feeding roller shaft and rotatably connected to the inner wall of the steel feeding roller shaft. The oil storage box is fixedly installed at one end of a slide bar. A ventilation pipe is fixedly installed at the bottom of the oil storage box. A first oil pipe is fixedly installed on one side of the oil storage box. Both the ventilation pipe and the first oil pipe are placed inside the inner wall of the slide bar. A pushing oil plate is arranged inside the oil storage box. Lubricating oil is introduced into the top of the pushing oil plate. By externally connecting an air inlet assembly at the ventilation pipe, when the steel feeding roller shaft rotates to drive the stainless steel material to move, the gas inside the ventilation pipe pushes the pushing oil plate inside the oil storage box to move upward. When the pushing oil plate moves upward, it pushes the lubricating oil inside the oil storage box to move upward. Through the leakage openings on the steel feeding roller shaft and the oil storage box, when the steel feeding roller shaft drives the stainless steel material to move, the pushing oil plate pushes the lubricating oil inside the oil storage box to flow out from the leakage opening to the bottom of the stainless steel material, so as to spray lubricating oil on the lower surface of the stainless steel material, thereby reducing the friction between the stainless steel material and the steel holding block during bending, avoiding scratches and deformation. The setting of the first oil pipe is to facilitate the oil inlet into the oil storage cylinder.

[0013] Preferably, the upper spraying assembly includes an oil storage cylinder which is fixedly installed in the middle of the inner wall of the steel feeding roller shaft. A plurality of oil outlet torque boxes are fixedly installed on the inner wall of the steel feeding roller shaft. A plurality of flow oil pipes are fixedly installed between the plurality of oil outlet torque boxes and the oil storage cylinder. A plurality of push rod frames are slidably connected to the inner wall of the steel feeding roller shaft. A plurality of torque rods are fixedly installed on one side of the plurality of push rod frames. The outer walls of the plurality of torque rods are respectively slidably connected to the inner walls of the plurality of flow oil pipes. A plurality of blocking blocks are fixedly installed at one ends of the plurality of torque rods. The plurality of blocking blocks are respectively slidably connected to the oil inlet openings at the tops of the plurality of oil outlet torque boxes. A second oil pipe is fixedly installed on the outer wall of the oil storage cylinder. When the steel pressing roller shaft contacts the upper surface of the stainless steel material, the upper surface of the stainless steel material pushes the push rod frame inside the steel pressing roller shaft to move upward. When the push rod frame moves upward, it drives the blocking block to slide out from the oil inlet opening at the top of the oil outlet torque box through the torque rod. The lubricating oil inside the oil storage cylinder will flow out through the flow oil pipe into the oil outlet torque box, so that the lubricating oil flows to the upper surface of the stainless steel material, enabling the lubricating oil to reduce the friction between the steel pressing roller shaft and the upper surface of the stainless steel material during the bending operation of the stainless steel material, avoiding scratches and deformation. By spraying lubricating oil on the upper and lower surfaces of the stainless steel material, the friction during the bending operation of the stainless steel material can be reduced, thereby avoiding the phenomenon of wrinkles and scratches on the stainless steel material during bending. The setting of the second oil pipe is to facilitate the oil inlet into the oil storage cylinder.

[0014] Preferably, a plurality of shaft rods are fixedly installed on the outer wall of the oil storage cylinder. The plurality of shaft rods are respectively slidably connected to the inner walls of a plurality of push rod frames. A plurality of return springs are fixedly installed between the plurality of push rod frames and the oil storage cylinder. When the push rod frame is pressed and moves, the push rod frame squeezes the return spring and moves on the shaft rod. By the rotation of the pressing steel roller shaft, when the push rod frame loses the limiting thrust on the upper surface of the stainless steel material, under the action of the elastic restoring force of the return spring, the push rod frame is reset, and the plug block will block the oil inlet at the top of the oil outlet torque box again, preventing excessive outflow of lubricating oil during the operation of bending the steel by rotating the pressing steel roller shaft, and avoiding waste.

[0015] Preferably, on the other end of one side of the power box, an oil blowing lower plate is fixedly installed. The oil blowing lower plate is arranged on one side of the steel outlet roller shaft, and the top of the oil blowing lower plate is flush with the top of the steel outlet roller shaft. An oil blowing upper plate is arranged directly above the oil blowing lower plate. The oil blowing upper plate is rotatably connected to the inner wall of the power box. Through holes are respectively opened in the oil blowing lower plate and the oil blowing upper plate for connecting an external air source. By connecting a blowing device to the oil blowing lower plate and the oil blowing upper plate, when the bending operation of the stainless steel material is completed, the stainless steel material slides out from the other side of the housing. The oil blowing lower plate and the oil blowing upper plate on the other side blow the upper and lower surfaces of the stainless steel material, blowing off the lubricating oil adhered to the stainless steel material. On the one hand, it can clean the surface of the stainless steel material, and on the other hand, it can also recover the lubricating oil, avoiding excessive waste and saving resources.

[0016] Preferably, a return plate wheel is fixedly installed on one side of the oil blowing upper plate. A toothed rod is slidably connected to the inner wall of the power box. A counterweight block is fixedly installed at the bottom of the toothed rod. The teeth on the toothed rod are meshed with the teeth on the return plate wheel. Since the bending angle of the stainless steel material is different, the position where the stainless steel material slides out of the housing will be different. When one end of the stainless steel material slides out of the housing, one end of the stainless steel material pushes the oil blowing upper plate to rotate on the power box, and the return plate wheel will drive the toothed rod to move upward, so that the oil blowing upper plate rotates following the bending degree of the stainless steel material, keeping the oil blowing upper plate always on the upper surface of the stainless steel material. When the stainless steel material completely slides out of the housing, due to the counterweight block arranged at the bottom end of the toothed rod, the oil blowing upper plate loses the thrust of the stainless steel material, and the oil blowing upper plate will be reset.

[0017] Preferably, oil collecting boxes are fixedly installed at the bottoms of both sides of the power box. The oil collecting boxes are arranged directly below the steel outlet roller shaft and the steel inlet roller shaft. The oil collecting boxes collect the lubricating oil flowing down in the device. By connecting an oil return device to the oil collecting boxes and then connecting the oil through pipe 1 and the oil through pipe 2 to the oil return device, the recycling of the lubricating oil can be realized.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. A stainless - steel bending device according to the present invention, during the process of bending stainless - steel materials, the lower spraying component sprays lubricating oil on the lower surface of the stainless - steel, reducing the friction between the stainless - steel material and the molten - steel block, and the upper spraying component sprays lubricating oil on the upper surface of the stainless - steel, reducing the friction between the pressing - steel roller shaft and the upper surface of the stainless - steel material. Thus, the friction during the bending operation of the stainless - steel material is reduced, avoiding the strain and deformation of the stainless - steel material, and thereby reducing the appearance of wrinkles and scratches on the surface of the stainless - steel material during stretch - bending.

[0020] 2. A stainless - steel bending device according to the present invention, by externally connecting a blowing device to the oil - blowing lower plate and the oil - blowing upper plate. When the bending operation of the stainless - steel material is completed, the stainless - steel material slides out from the other side of the housing. The oil - blowing lower plate and the oil - blowing upper plate on the other side blow the upper and lower surfaces of the stainless - steel material, blowing off the lubricating oil adhering to the stainless - steel material. On the one hand, it can clean the surface of the stainless - steel material, and on the other hand, it can also recycle the lubricating oil, avoiding unnecessary waste and saving resources.

[0035] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0036] As Figures 1 to 12 shown, a stainless steel bending device according to an embodiment of the present invention includes a housing 1. A power box 6 is fixedly installed in the middle of the inner wall of the housing 1. A steel discharging roller shaft 14 and a steel feeding roller shaft 9 are symmetrically and rotatably connected to both sides of the power box 6. Pressing steel roller shafts 11 are symmetrically arranged on both sides of the power box 6. The pressing steel roller shafts 11 are arranged directly above the middle of the steel discharging roller shaft 14 and the steel feeding roller shaft 9. Material inlets 10 are opened at one ends of both sides of the power box 6. Angle adjustment motors 12 are fixedly installed on both sides of the power box 6. Output ends of the two angle adjustment motors 12 are fixedly installed with steel holding blocks 13. The two steel holding blocks 13 are respectively placed directly below the two pressing steel roller shafts 11. A through groove adapted to the material inlet 10 is opened on the surface of the housing 1. A lower spraying assembly is arranged inside the steel feeding roller shaft 9. The lower spraying assembly is used for spraying lubricating oil on the lower surface of the stainless steel. An upper spraying assembly is arranged inside the pressing steel roller shaft 11. The upper spraying assembly is used for spraying lubricating oil on the upper surface of the stainless steel;

[0037] When the friction between the pulling roller and the stainless steel is too large, it is very easy for wrinkles and scratches to appear on the surface of the stainless steel when it is pulled out, which has a negative impact on the performance and appearance of the material;

[0038] The stainless steel material to be bent is placed into the inlet housing 1 from the inlet plate opening 10. The inlet steel roller shaft 9 inside the housing 1 drives the stainless steel material to move forward. While moving, the lower spraying assembly inside the inlet steel roller shaft 9 sprays lubricating oil on the lower surface of the stainless steel. Subsequently, one end of the stainless steel is driven by the rotation of the inlet steel roller shaft 9 to be placed on the outlet steel roller shaft 14. The stainless steel will be placed between the inlet steel roller shaft 9 and the power box 6. Then, by controlling the angle-adjusting motor 12 to drive the steel holding block 13 to move. When the steel holding block 13 moves to a certain position, the angle formed between the steel holding block 13, the outlet steel roller shaft 14, and the inlet steel roller shaft 9 at this time is the angle by which the stainless steel material needs to be bent. Then, control the pressing steel roller shaft 11 to move downward. When the pressing steel roller shaft 11 contacts the stainless steel material, the upper spraying assembly inside the pressing steel roller shaft 11 sprays lubricating oil on the upper surface of the stainless steel. Then, control the pressing steel roller shaft 11 to continue moving downward. During the downward movement, the pressing steel roller shaft 11 squeezes the steel body of the stainless steel material to move towards the steel holding block 13. When the lower surface of the stainless steel material contacts the top of the steel holding block 13, stop moving the pressing steel roller shaft 11. Then, continue to drive the inlet steel roller shaft 9 and the outlet steel roller shaft 14 to rotate. When the two rotate, they drive the remaining stainless steel material to move into the housing 1. Subsequently, through the limiting squeezing force of the pressing steel roller shaft 11, the stainless steel material will be bent to the specified angle, thus realizing the bending operation of the stainless steel material. When the stainless steel material moves in the housing 1, the upper spraying assembly inside the pressing steel roller shaft 11 sprays lubricating oil on the upper surface of the stainless steel material to reduce the friction between the pressing steel roller shaft 11 and the upper surface of the stainless steel material. The lower spraying assembly inside the inlet steel roller shaft 9 sprays lubricating oil on the lower surface of the stainless steel material to reduce the friction between the stainless steel material and the steel holding block 13. Through the cooperation of the two, the friction during the bending of the stainless steel material is reduced, avoiding pulling and deformation, thus solving the problem in the prior art that when the friction between the pulling roller and the stainless steel material is too large, it is extremely easy for wrinkles and scratches to appear on the surface of the stainless steel when it is pulled out, which has a negative impact on the performance and appearance of the material. Here, it should be noted that the tops of the inlet steel roller shaft 9, the outlet steel roller shaft 14, and the steel holding block 13 should be on the same horizontal line in the initial state.

[0039] As Figures 4 to 5 shown, a driving wheel motor 35 is fixedly installed in the middle of the inner wall of the power box 6. The output ends of the driving wheel motor 35 are symmetrically and fixedly installed with driving wheels 18. The inner wall of the power box 6 is symmetrically and rotatably connected with two groups of transmission wheels 20. The teeth on the two groups of transmission wheels 20 are respectively meshed with the teeth on the two driving wheels 18. One side of the two groups of transmission wheels 20 is respectively fixedly connected with one end of the two outlet steel roller shafts 14 and the inlet steel roller shaft 9;

[0040] During operation, the drive wheel 18 is rotated by the drive wheel motor 35. When the drive wheel 18 rotates, it drives the transmission wheel 20 to rotate through tooth engagement, thereby driving the steel inlet roller shaft 9 and the steel outlet roller shaft 14 to rotate, realizing the pulling of stainless steel. By pulling and bending the stainless steel, this device can be applied to stainless steel of different lengths. By controlling the operation of the drive wheel motor 35, the rotation and stop of the steel outlet roller shaft 14 and the steel inlet roller shaft 9 can be realized. With two workstations symmetrically arranged in this device, the bending efficiency of stainless steel can be increased during the bending operation, which is more conducive to the operation.

[0041] As Figures 4 to 5 shown, a hydraulic cylinder 2 is fixedly installed on the top of the power box 6. The output end of the hydraulic cylinder 2 is fixedly installed with a connecting frame 17. The two ends of the connecting frame 17 are respectively rotatably connected to one side of the two steel pressing roller shafts 11. The two ends of the connecting frame 17 are slidably connected to the inner wall of the power box 6;

[0042] During operation, by controlling the hydraulic cylinder 2 to drive the connecting frame 17 to move, the position of the steel pressing roller shaft 11 can be moved, so that when the stainless steel is placed between the steel inlet roller shaft 9 and the steel outlet roller shaft 14, the steel pressing roller shaft 11 can squeeze the stainless steel for bending operation. By squeezing and bending the stainless steel with the steel pressing roller shaft 11, this device can be applied to stainless steel of different thicknesses. It should be noted here that the initial position of the steel pressing roller shaft 11 should be at the highest position directly above the middle between the steel outlet roller shaft 14 and the steel inlet roller shaft 9.

[0043] As Figures 3 to 4 shown, a telescopic cylinder 8 is fixedly installed at the bottom of the power box 6. The output end of the telescopic cylinder 8 is symmetrically fixedly installed with baffles 4. Two groups of sliding rods 7 are symmetrically fixedly installed on the inner wall of the housing 1. One ends of the two groups of sliding rods 7 are respectively rotatably connected to the inner walls of the two steel outlet roller shafts 14 and the steel inlet roller shaft 9. One sides of the two baffles 4 are fixedly installed with limit blocks 3. The two limit blocks 3 are both slidably connected to the outer wall of the housing 1. The two groups of sliding rods 7 are respectively slidably connected to the inner walls of the two baffles 4;

[0044] When the stainless steel is put into the housing 1, by controlling the telescopic cylinder 8 to drive the sliding rods 7 to move, the limit blocks 3 slide on the outer wall of the housing 1. When the sliding rods 7 and the limit blocks 3 contact one side of the stainless steel, stop the telescopic cylinder 8 from moving the sliding rods 7. At this time, the sliding rods 7 provide a limit block for the stainless steel, preventing the stainless steel from running out between the steel outlet roller shaft 14 and the steel inlet roller shaft 9 due to the excessive extrusion force of the steel pressing roller shaft 11 during bending. At the same time, by using the sliding rods 7 to provide a limit block for the stainless steel, this device can also be applied to stainless steel of different widths.

[0045] As Figures 9 to 10As shown in the figure, the lower spraying assembly includes an oil storage box 31. The oil storage box 31 is placed inside the inner wall of the steel feeding roller shaft 9 and is rotatably connected to the inner wall of the steel feeding roller shaft 9. The oil storage box 31 is fixedly installed at one end of the sliding rod 7. A ventilation pipe 32 is fixedly installed at the bottom of the oil storage box 31. A first oil pipe 33 is fixedly installed on one side of the oil storage box 31. Both the ventilation pipe 32 and the first oil pipe 33 are placed inside the inner wall of the sliding rod 7. A pushing oil plate 34 is arranged inside the oil storage box 31, and lubricating oil is introduced into the top of the pushing oil plate 34;

[0046] By externally connecting an air intake assembly at the ventilation pipe 32, when the steel feeding roller shaft 9 rotates to drive the stainless steel material to move, the gas in the ventilation pipe 32 pushes the pushing oil plate 34 inside the oil storage box 31 to move upward. When the pushing oil plate 34 moves upward, it pushes the lubricating oil inside the oil storage box 31 to move upward. Through the leakage openings on the steel feeding roller shaft 9 and the oil storage box 31, when the steel feeding roller shaft 9 drives the stainless steel material to move, the pushing oil plate 34 pushes the lubricating oil inside the oil storage box 31 to flow out from the leakage opening to the bottom of the stainless steel material, thereby spraying lubricating oil on the lower surface of the stainless steel material, reducing the friction between the stainless steel material and the steel holding block 13 during bending, avoiding scratches and deformation. The setting of the first oil pipe 33 is to facilitate the oil intake into the oil storage cylinder 24.

[0047] As Figures 7 to 8 shown in the figure, the upper spraying assembly includes an oil storage cylinder 24. The oil storage cylinder 24 is fixedly installed in the middle of the inner wall of the steel feeding roller shaft 9. A plurality of oil outlet torque boxes 26 are fixedly installed on the inner wall of the steel feeding roller shaft 9. A plurality of flow oil pipes 25 are fixedly installed between the plurality of oil outlet torque boxes 26 and the oil storage cylinder 24. A plurality of push rod frames 27 are slidably connected to the inner wall of the steel feeding roller shaft 9. A plurality of torque rods 19 are fixedly installed on one side of the plurality of push rod frames 27. The outer walls of the plurality of torque rods 19 are respectively slidably connected to the inner walls of the plurality of flow oil pipes 25. A plug 29 is fixedly installed at one end of each of the plurality of torque rods 19. The plurality of plugs 29 are respectively slidably connected to the oil inlet openings at the tops of the plurality of oil outlet torque boxes 26. A second oil pipe 36 is fixedly installed on the outer wall of the oil storage cylinder 24;

[0048] When the steel pressing roller shaft 11 contacts the upper surface of the stainless steel material, the upper surface of the stainless steel material pushes the push rod frame 27 inside the steel pressing roller shaft 11 to move upward. When the push rod frame 27 moves upward, it drives the plug 29 to slide out from the oil inlet opening at the top of the oil outlet torque box 26 through the torque rod 19. The lubricating oil inside the oil storage cylinder 24 will flow out through the flow oil pipe 25 into the oil outlet torque box 26, so that the lubricating oil flows to the upper surface of the stainless steel material, reducing the friction between the steel pressing roller shaft 11 and the upper surface of the stainless steel material during the bending operation of the stainless steel material, avoiding scratches and deformation. By performing lubricating spraying operations on the upper and lower surfaces of the stainless steel material, the friction during the bending operation of the stainless steel material can be reduced, thereby avoiding the phenomenon of wrinkles and scratches on the stainless steel material during bending. The setting of the second oil pipe 36 is to facilitate the oil intake into the oil storage cylinder 24.

[0049] As Figures 7 to 8 shown, a plurality of shaft rods 30 are fixedly installed on the outer wall of the oil storage cylinder 24. The plurality of shaft rods 30 are respectively slidably connected to the inner walls of the plurality of push rod frames 27. A plurality of return springs 28 are fixedly installed between the plurality of push rod frames 27 and the oil storage cylinder 24;

[0050] When the push rod frame 27 is pressed and moves, the push rod frame 27 squeezes the return spring 28 to move on the shaft rod 30. By the rotation of the pressing steel roller shaft 11, when the push rod frame 27 loses the limiting thrust on the upper surface of the stainless steel material, under the action of the elastic restoring force of the return spring 28, the push rod frame 27 is reset, and the blocking block 29 will block the oil inlet at the top of the oil outlet torque box 26 again, preventing too much lubricating oil from flowing out during the operation of pulling and bending the steel by the rotation of the pressing steel roller shaft 11 and avoiding waste.

[0051] As Figures 6 to 12 shown, at the other end of one side of the power box 6, an oil blowing lower plate 15 is fixedly installed. The oil blowing lower plate 15 is arranged on one side of the steel outlet roller shaft 14. The top of the oil blowing lower plate 15 is flush with the top of the steel outlet roller shaft 14. An oil blowing upper plate 16 is arranged directly above the oil blowing lower plate 15. The oil blowing upper plate 16 is rotatably connected to the inner wall of the power box 6. Through holes are respectively opened in the oil blowing lower plate 15 and the oil blowing upper plate 16 for connecting an external air source;

[0052] By connecting a blowing device to the oil blowing lower plate 15 and the oil blowing upper plate 16, when the bending operation of the stainless steel material is completed, the stainless steel material slides out from the other side of the housing 1. The oil blowing lower plate 15 and the oil blowing upper plate 16 on the other side blow the upper and lower surfaces of the stainless steel material to blow off the lubricating oil adhered to the stainless steel material. On the one hand, it can clean the surface of the stainless steel material, and on the other hand, it can also recover the lubricating oil, avoiding unnecessary waste and saving resources.

[0053] As Figures 5 to 11 shown, a return plate wheel 22 is fixedly installed on one side of the oil blowing upper plate 16. A toothed rod 21 is slidably connected to the inner wall of the power box 6. A counterweight block 23 is fixedly installed at the bottom of the toothed rod 21. The teeth on the toothed rod 21 are engaged with the teeth on the return plate wheel 22;

[0054] During operation, due to different bending angles of the stainless steel material, the position where the stainless steel material slides out of the housing 1 will be different. When one end of the stainless steel material slides out of the housing 1, one end of the stainless steel material pushes the oil-blowing upper plate 16 to rotate on the power box 6, and the return plate wheel 22 will drive the toothed rod 21 to move upward, so that the oil-blowing upper plate 16 rotates following the bending degree of the stainless steel material, making the oil-blowing upper plate 16 always placed on the upper surface of the stainless steel material. When the stainless steel material completely slides out of the housing 1, through the counterweight block 23 arranged at the bottom end of the toothed rod 21, the oil-blowing upper plate 16 loses the thrust of the stainless steel material, and the oil-blowing upper plate 16 will reset. It should be noted here that the weight of the counterweight block 23 needs to be obtained through actual measurement.

[0055] As Figures 3 to 6 shown, oil collecting boxes 5 are fixedly installed at both bottom sides of the power box 6, and the oil collecting boxes 5 are placed directly below the steel outlet roller shaft 14 and the steel inlet roller shaft 9;

[0056] During operation, the oil collecting boxes 5 collect the lubricating oil flowing down in the device. By externally connecting an oil return device at the oil collecting boxes 5, and then connecting the first oil pipe 33 and the second oil pipe 36 to the oil return device, the recycling of the lubricating oil can be realized.

[0057] Working principle: Put the stainless steel material to be bent into the inlet of the feeding plate 10 and into the housing 1. The feeding steel roller shaft 9 in the housing 1 drives the stainless steel material to move forward. While moving, the lower spraying component in the feeding steel roller shaft 9 sprays lubricating oil on the lower surface of the stainless steel. Subsequently, the rotation of the feeding steel roller shaft 9 drives one end of the stainless steel onto the discharging steel roller shaft 14, and the stainless steel is placed between the feeding steel roller shaft 9 and the power box 6. Then, control the angle-adjusting motor 12 to drive the steel holding block 13 to move. When the steel holding block 13 moves to a certain position, the angle formed between the steel holding block 13, the discharging steel roller shaft 14, and the feeding steel roller shaft 9 is the angle by which the stainless steel material needs to be bent. Then, control the pressing steel roller shaft 11 to move downward. When the pressing steel roller shaft 11 touches the stainless steel material, the upper spraying component in the pressing steel roller shaft 11 sprays lubricating oil on the upper surface of the stainless steel. Then, control the pressing steel roller shaft 11 to continue moving downward. During the downward movement, the pressing steel roller shaft 11 squeezes the steel body of the stainless steel material towards the steel holding block 13. When the lower surface of the stainless steel material touches the top of the steel holding block 13, stop moving the pressing steel roller shaft 11. Then, continue to drive the feeding steel roller shaft 9 and the discharging steel roller shaft 14 to rotate. When both are rotating, they drive the remaining stainless steel material into the housing 1. Subsequently, through the limiting extrusion force of the pressing steel roller shaft 11, the stainless steel material will be bent to the specified angle, thus realizing the bending operation of the stainless steel material. When the stainless steel material moves in the housing 1, the upper spraying component in the pressing steel roller shaft 11 sprays lubricating oil on the upper surface of the stainless steel material to reduce the friction between the pressing steel roller shaft 11 and the upper surface of the stainless steel material, and the lower spraying component in the feeding steel roller shaft 9 sprays lubricating oil on the lower surface of the stainless steel material to reduce the friction between the stainless steel material and the steel holding block 13. Through the cooperation of the two, the friction during the bending of the stainless steel material is reduced, avoiding scratches and deformation;

[0058] Drive the driving wheel 18 to rotate through the driving wheel motor 35. When the driving wheel 18 rotates, it drives the transmission wheel 20 to rotate through tooth engagement, thereby driving the feeding steel roller shaft 9 and the discharging steel roller shaft 14 to rotate, realizing the pulling of the stainless steel material. By pulling and bending the stainless steel material, this device can be applicable to stainless steel materials of different lengths. By controlling the operation of the driving wheel motor 35, the rotation and stop of the discharging steel roller shaft 14 and the feeding steel roller shaft 9 can be realized. Since this device has two symmetrically arranged working stations, the bending efficiency of the stainless steel material can be increased during the bending operation, which is more conducive to the operation;

[0059] Control the hydraulic cylinder 2 to drive the connecting frame 17 to move, thereby realizing the position movement of the pressing steel roller shaft 11, so that when the stainless steel material is placed between the feeding steel roller shaft 9 and the discharging steel roller shaft 14, the pressing steel roller shaft 11 can squeeze the stainless steel material for bending operation. By squeezing and bending the stainless steel material with the pressing steel roller shaft 11, this device can be applicable to stainless steel materials of different thicknesses;

[0060] When the stainless steel material is placed into the housing 1, the telescopic cylinder 8 is controlled to drive the sliding rod 7 to move. The limit block 3 slides on the outer wall of the housing 1. When the sliding rod 7 and the limit block 3 contact one side of the stainless steel material, the movement operation of the telescopic cylinder 8 on the sliding rod 7 is stopped. At this time, the sliding rod 7 performs a limit blocking on the stainless steel material, preventing the stainless steel material from running out between the steel outlet roller shaft 14 and the steel inlet roller shaft 9 due to excessive extrusion force of the steel pressing roller shaft 11 when the stainless steel material is bent. At the same time, by performing a limit blocking on the stainless steel material with the sliding rod 7, this device can also be applicable to stainless steel materials of different widths;

[0061] By externally connecting an air intake component at the ventilation pipe 32, when the steel inlet roller shaft 9 rotates to drive the stainless steel material to move, the gas in the ventilation pipe 32 pushes the oil pushing plate 34 in the oil storage box 31 to move upward. When the oil pushing plate 34 moves upward, it pushes the lubricating oil in the oil storage box 31 to move upward. Through the leakage ports on the steel inlet roller shaft 9 and the oil storage box 31, when the steel inlet roller shaft 9 drives the stainless steel material to move, the oil pushing plate 34 pushes the lubricating oil in the oil storage box 31 to flow from the leakage port to the bottom of the stainless steel material, thereby performing a lubricating oil spraying operation on the lower surface of the stainless steel material, reducing the friction between the stainless steel material and the steel holding block 13 during bending, avoiding scratches and deformation. The setting of the first ventilation pipe 33 is for facilitating the oil inlet into the oil storage cylinder 24;

[0062] When the steel pressing roller shaft 11 contacts the upper surface of the stainless steel material, the upper surface of the stainless steel material pushes the push rod frame 27 in the steel pressing roller shaft 11 to move upward. When the push rod frame 27 moves upward, it drives the blocking block 29 to slide out from the oil inlet of the top of the oil outlet torque box 26 through the torque rod 19. The lubricating oil in the oil storage cylinder 24 will flow out through the flow oil pipe 25 into the oil outlet torque box 26, so that the lubricating oil flows to the upper surface of the stainless steel material. When the steel pressing roller shaft 11 performs a bending operation on the stainless steel material, the lubricating oil reduces the friction between the steel pressing roller shaft 11 and the upper surface of the stainless steel material, avoiding scratches and deformation. By performing a lubricating spraying operation on the upper and lower surfaces of the stainless steel material, the friction during the bending operation of the stainless steel material can be reduced, thus avoiding the phenomenon of wrinkles and scratches on the stainless steel material during bending. The setting of the second ventilation pipe 36 is for facilitating the oil inlet into the oil storage cylinder 24;

[0063] When the push rod frame 27 is pressed and moves, the push rod frame 27 squeezes the return spring 28 to move on the shaft rod 30. Through the rotation of the steel pressing roller shaft 11, when the push rod frame 27 loses the limit thrust of the upper surface of the stainless steel material, under the action of the elastic restoring force of the return spring 28, the push rod frame 27 is reset, and the blocking block 29 will block the oil inlet of the top of the oil outlet torque box 26 again, preventing excessive outflow of the lubricating oil during the rotation and steel bending operation of the steel pressing roller shaft 11 and avoiding waste;

[0064] By externally connecting a blowing device to the oil-blowing lower plate 15 and the oil-blowing upper plate 16, when the bending operation of the stainless steel material is completed, the stainless steel material slides out from the other side of the housing 1. As the stainless steel material slides out from the other side, the oil-blowing lower plate 15 and the oil-blowing upper plate 16 on the other side blow the upper and lower surfaces of the stainless steel material, blowing off the lubricating oil adhered to the stainless steel material. On the one hand, it can clean the surface of the stainless steel material, and on the other hand, it can also recycle the lubricating oil, avoiding unnecessary waste and saving resources;

[0065] Due to different bending angles of the stainless steel material, the position where the stainless steel material slides out from the housing 1 will be different. When one end of the stainless steel material slides out from the housing 1, one end of the stainless steel material pushes the oil-blowing upper plate 16 to rotate on the power box 6, and the return plate wheel 22 will drive the toothed rod 21 to move upward, so that the oil-blowing upper plate 16 rotates following the bending degree of the stainless steel material, keeping the oil-blowing upper plate 16 always on the upper surface of the stainless steel material. When the stainless steel material completely slides out from the housing 1, due to the counterweight 23 provided at the bottom end of the toothed rod 21, the oil-blowing upper plate 16 loses the thrust of the stainless steel material and the oil-blowing upper plate 16 will reset;

[0066] The oil collecting box 5 collects the lubricating oil flowing down in the device. By externally connecting an oil return device to the oil collecting box 5 and then connecting the oil pipe 33 and the oil pipe 36 to the oil return device, the recycling of the lubricating oil can be realized.
