Description

Technical Field

[0001] The invention belongs to the technical field of steel material processing, in particular to a stainless steel bending device. Background Art

[0002] Stainless steel bending equipment is a machine specially used for bending stainless steel pipes, plates, etc. These equipment usually adopt mechanical transmission and control system, which can realize fast and accurate bending operation and are widely used in pipeline installation, decoration, industrial manufacturing and other fields. There are many types of stainless steel bending equipment, including but not limited to stainless steel pipe bending machine, stainless steel plate bending machine, CNC bending machine, etc. They differ in structural design, control accuracy, degree of automation, etc. to meet different processing needs and improve production efficiency.

[0003] A Chinese patent with publication number CN118080639A discloses a U-shaped steel bending device, including a moving roller group and two stationary roller groups. The steel workpiece passes between the moving roller group and the two stationary roller groups to form a curved 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 supports the inside of the U-shaped groove during the bidirectional bending of the steel workpiece by installing functional parts. The functional parts include support wheels for side plate support and support sleeves 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 bending in different directions, different functional parts can be selected on the functional support roller to maintain effective support of the U-shaped steel at the bending point and reduce the deformation of the U-shaped steel during bending.

[0004] In the current existing technology, when stainless steel is bent, the stainless steel is basically bent by stretching. When the stretching roller contacts the surface of the stainless steel and pulls it during the stretching process, if the friction between the stretching 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.

[0005] To this end, 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, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: a stainless steel bending device described in the present invention comprises a shell, a power box is fixedly installed in the middle of the inner wall of the shell, a steel-out roller and a steel-in roller are symmetrically rotatably connected on both sides of the power box, steel-pressing rollers are symmetrically arranged on both sides of the power box, and the steel-pressing rollers are arranged directly above the steel-out rollers and the steel-in rollers, and a feeding plate opening is provided at one end of both sides of the power box, an angle adjustment motor is fixedly installed on both sides of the power box, and steel holding blocks are fixedly installed at the output ends of the two angle adjustment motors, and the two steel holding blocks are respectively placed directly below the two steel-pressing rollers, a through groove matched with the feeding plate opening is provided on the surface of the shell, a lower spray assembly is arranged inside the steel-in roller, and the lower spray assembly is used to spray lubricating oil on the lower surface of the stainless steel, and an upper spray assembly is arranged inside the steel-pressing roller, and the upper spray assembly is used to spray lubricating oil on the upper surface of the stainless steel; The stainless steel material to be bent is placed into the shell through the inlet plate opening, and the steel-feed roller in the shell drives the stainless steel material to move forward. While moving, the lower spray assembly in the steel-feed roller sprays lubricating oil on the lower surface of the stainless steel. Then, the steel-feed roller rotates to drive one end of the stainless steel to be placed on the steel-outlet roller, and the stainless steel is placed between the steel-feed roller and the power box. Then, the angle adjustment motor is controlled to drive the steel block to move. When the steel block moves to a certain position, the angle formed between the steel block, the steel-outlet roller and the steel-feed roller is the angle at which the stainless steel material needs to be bent. Then, the steel-pressing roller is controlled to move downward. When the steel-pressing roller contacts the stainless steel material, the upper spray assembly in the steel-pressing roller sprays lubricating oil on the upper surface of the stainless steel. Then, the steel-pressing roller is controlled to continue to move downward. During the downward movement, the steel-pressing roller squeezes the stainless steel material. The steel body of the stainless steel moves toward the steel block. When the lower surface of the stainless steel contacts the top of the steel block, the steel pressing roller stops moving, and then the steel inlet roller and the steel outlet roller continue to be driven to rotate. When the two rotate, they drive the remaining stainless steel to move into the shell. Then, through the limited extrusion pressure of the steel pressing roller, the stainless steel will bend to the specified angle, thereby realizing the bending operation of the stainless steel. When the stainless steel moves in the shell, the upper spraying component in the steel pressing roller sprays lubricating oil on the upper surface of the stainless steel to reduce the friction between the steel pressing roller and the upper surface of the stainless steel. The lower spraying component in the steel inlet roller sprays lubricating oil on the lower surface of the stainless steel to reduce the friction between the stainless steel and the steel block. The two work together to reduce the friction of the stainless steel during bending, thereby avoiding strain and deformation.

One side of the two sets of transmission wheels is respectively fixedly connected to one end of the two steel-outlet rollers and the steel-inlet roller. The drive wheel is driven to rotate by the drive wheel motor. When the drive wheel rotates, it drives the drive wheel to rotate through the meshing of teeth, thereby driving the steel-inlet roller and the steel-outlet roller to rotate, so as to pull the stainless steel material. By pulling and bending the stainless steel material, the device can be suitable for stainless steel materials of different lengths. By controlling the operation of the drive wheel motor, the rotation and stopping of the steel-outlet roller and the steel-inlet roller are realized.

When the sliding rod and the limiting block contact one side of the stainless steel material, the telescopic cylinder stops moving the sliding rod. At this time, the sliding rod performs a limit blocking on the stainless steel material to prevent the stainless steel material from running out from between the steel-outlet roller shaft and the steel-inlet roller shaft due to excessive extrusion pressure of the steel pressing roller shaft when the stainless steel material is bent. At the same time, the limit blocking of the stainless steel material by the sliding rod can also make the device suitable for stainless steel materials of different widths.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 12 As shown, a stainless steel bending device according to an embodiment of the present invention comprises a shell 1, a power box 6 is fixedly installed in the middle of the inner wall of the shell 1, a steel-out roller 14 and a steel-in roller 9 are symmetrically rotatably connected on both sides of the power box 6, steel-pressing rollers 11 are symmetrically arranged on both sides of the power box 6, and the steel-pressing rollers 11 are arranged directly above the steel-out rollers 14 and the steel-in rollers 9, and a feeding plate opening 10 is provided at one end of both sides of the power box 6, and an angle adjustment motor 12 is fixedly installed on both sides of the power box 6, and steel holding blocks 13 are fixedly installed at the output ends of the two angle adjustment motors 12, and the two steel holding blocks 13 are respectively placed directly below the two steel-pressing rollers 11, and a through groove matching the feeding plate opening 10 is provided on the surface of the shell 1, and a lower spraying assembly is arranged inside the steel-in roller 9, and the lower spraying assembly is used to spray lubricating oil on the lower surface of the stainless steel, and an upper spraying assembly is arranged inside the steel-pressing roller 11, and the upper spraying assembly is used to spray lubricating oil on the upper surface of the stainless steel; When the friction between the pulling roller and the stainless steel is too great, 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. The stainless steel material to be bent is placed into the housing 1 from the inlet plate opening 10, and the steel inlet roller 9 in the housing 1 drives the stainless steel material to move forward. While moving, the lower spray assembly in the steel inlet roller 9 sprays lubricating oil on the lower surface of the stainless steel. Then, the steel inlet roller 9 rotates to drive one end of the stainless steel to be placed on the steel outlet roller 14, and the stainless steel is placed between the steel inlet roller 9 and the power box 6. Then, the steel block 13 is driven to move by controlling the angle adjustment motor 12. When the steel block 13 moves to a certain position, the steel block 1 3 and the angle formed between the steel-outlet roller 14 and the steel-inlet roller 9 is the angle at which the stainless steel material needs to be bent. Then the steel-pressing roller 11 is controlled to move downward. When the steel-pressing roller 11 contacts the stainless steel material, the upper spraying assembly in the steel-pressing roller 11 sprays lubricating oil on the upper surface of the stainless steel. Then the steel-pressing roller 11 is controlled to continue to move downward. During the downward movement, the steel-pressing roller 11 squeezes the steel body of the stainless steel material and moves toward the steel block 13. When the lower surface of the stainless steel material contacts the top of the steel block 13, the steel-pressing roller 11 is stopped and then continued. The steel feed roller 9 and the steel discharge roller 14 are driven to rotate. When the two rotate, they drive the remaining stainless steel material to move into the shell 1. Then, through the limiting extrusion pressure of the steel pressing roller 11, the stainless steel material will bend to the specified angle, thereby realizing the bending operation of the stainless steel material. When the stainless steel material moves in the shell 1, the upper spray component in the steel pressing roller 11 sprays lubricating oil on the upper surface of the stainless steel material to reduce the friction between the steel pressing roller 11 and the upper surface of the stainless steel material. The lower spray component in the steel feed roller 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 block 13. Through the cooperation of the two, the friction of the stainless steel material during bending is reduced, and strain and deformation are avoided, thereby 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 very easy to cause wrinkles and strain marks 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. It should be noted here that the tops of the steel feed roller 9, the steel discharge roller 14 and the steel block 13 should be on the same horizontal line in the initial state.

[0024] like Figures 4 to 5 As shown, a drive wheel motor 35 is fixedly installed in the middle of the inner wall of the power box 6, and a drive wheel 18 is symmetrically fixedly installed at the output end of the drive wheel motor 35. The inner wall of the power box 6 is symmetrically rotatably connected with two sets of transmission wheels 20, and the teeth on the two sets of transmission wheels 20 are respectively meshed with the teeth on the two drive wheels 18, and one side of the two sets of transmission wheels 20 is respectively fixedly connected to one end of the two steel discharge roller shafts 14 and the steel feed roller shaft 9; During operation, the driving wheel 18 is driven to rotate by the driving wheel motor 35. When the driving wheel 18 rotates, the transmission wheel 20 is driven to rotate by the meshing of teeth, thereby driving the steel feed roller 9 and the steel discharge roller 14 to rotate, so as to pull the stainless steel material. By pulling and bending the stainless steel material, the device can be applied to stainless steel materials of different lengths. By controlling the operation of the driving wheel motor 35, the steel discharge roller 14 and the steel feed roller 9 can be rotated and stopped. By symmetrically opening two workstations in the device, the bending efficiency of the stainless steel material can be accelerated during the bending operation, which is more conducive to the operation.

[0025] like Figures 4 to 5 As shown, a hydraulic cylinder 2 is fixedly installed on the top of the power box 6, and a connecting frame 17 is fixedly installed on the output end of the hydraulic cylinder 2. The two ends of the connecting frame 17 are respectively rotatably connected to one side of the two pressing steel rollers 11, and the two ends of the connecting frame 17 are slidably connected to the inner wall of the power box 6; During operation, the connecting frame 17 is driven to move by controlling the hydraulic cylinder 2, thereby realizing the movement of the position of the steel pressing roller 11, so that when the stainless steel material is placed between the steel feeding roller 9 and the steel discharging roller 14, the steel pressing roller 11 can extrude the stainless steel material for bending. By extruding and bending the stainless steel material through the steel pressing roller 11, the device can be applied to stainless steel materials of different thicknesses. It should be noted here that the initial position of the steel pressing roller 11 should be placed at the highest point directly above the steel discharging roller 14 and the steel feeding roller 9.

[0026] like Figure 3 to Figure 4 As shown, a telescopic cylinder 8 is fixedly installed at the bottom of the power box 6, and a baffle 4 is symmetrically fixedly installed at the output end of the telescopic cylinder 8. Two sets of slide bars 7 are symmetrically fixedly installed on the inner wall of the shell 1, and one end of the two sets of slide bars 7 is rotatably connected to the inner walls of the two steel-discharging roller shafts 14 and the steel-feeding roller shaft 9, respectively. A limit block 3 is fixedly installed on one side of the two baffles 4, and the two limit blocks 3 are slidably connected to the outer wall of the shell 1, and the two sets of slide bars 7 are slidably connected to the inner walls of the two baffles 4, respectively. When the stainless steel material is put into the shell 1, the sliding rod 7 is driven to move by controlling the telescopic cylinder 8, and the limit block 3 slides on the outer wall of the shell 1. When the sliding rod 7 and the limit block 3 contact one side of the stainless steel material, the telescopic cylinder 8 stops moving the sliding rod 7. At this time, the sliding rod 7 performs a limit block on the stainless steel material to prevent the stainless steel material from running out from between the steel outlet roller 14 and the steel inlet roller 9 due to excessive squeezing pressure of the steel pressing roller 11 when the stainless steel material is bent. At the same time, by limiting the stainless steel material with the sliding rod 7, the device can also be applied to stainless steel materials of different widths.

[0027] like Figures 9 and 10As shown, the lower spray assembly includes an oil storage box 31, which is placed on the inner wall of the steel feed roller shaft 9 and is rotatably connected to the inner wall of the steel feed roller shaft 9. The oil storage box 31 is fixedly installed on one end of the slide bar 7. A vent pipe 32 is fixedly installed on the bottom of the oil storage box 31, and an oil passage pipe 33 is fixedly installed on one side of the oil storage box 31. The vent pipe 32 and the oil passage pipe 33 are both placed on the inner wall of the slide bar 7. An oil push plate 34 is arranged inside the oil storage box 31, and lubricating oil is passed into the top of the oil push plate 34. By connecting an air intake assembly to the air vent 32, when the steel feed roller 9 rotates to drive the stainless steel material to move, the gas in the air vent 32 pushes the oil push plate 34 in the oil storage box 31 to move upward, and the oil push plate 34 pushes the lubricating oil in the oil storage box 31 to move upward when moving upward, through the steel feed roller 9 and the leakage on the oil storage box 31, when the steel feed roller 9 drives the stainless steel material to move, the oil push plate 34 pushes the lubricating oil in the oil storage box 31 to flow from the leakage to the bottom of the stainless steel material, thereby spraying the lubricating oil on the lower surface of the stainless steel material, thereby reducing the friction between the stainless steel material and the steel block 13 when bending, avoiding strain and deformation, and the setting of the oil vent 33 is to facilitate the oil supply to the oil storage cylinder 24.

[0028] like Figures 7 and 8 As shown, the upper spray assembly includes an oil storage cylinder 24, which is fixedly installed in the middle of the inner wall of the steel feed roller shaft 9, and a plurality of oil outlet torque boxes 26 are fixedly installed on the inner wall of the steel feed roller shaft 9, and a plurality of oil flow pipes 25 are fixedly installed between the plurality of oil outlet torque boxes 26 and the oil storage cylinder 24, and a plurality of push rod racks 27 are slidably connected to the inner wall of the steel feed roller shaft 9, and a plurality of torque rods 19 are fixedly installed on one side of the plurality of push rod racks 27, and the outer walls of the plurality of torque rods 19 are respectively slidably connected to the inner walls of the plurality of oil flow pipes 25, and a blocking block 29 is fixedly installed on one end of the plurality of torque rods 19, and the plurality of blocking blocks 29 are respectively slidably connected to the oil inlets at the tops of the plurality of oil outlet torque boxes 26, and an oil through pipe 236 is fixedly installed on the outer wall of the oil storage cylinder 24; When the pressing steel roller 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 pressing steel roller 11 to move upward. When moving upward, the push rod frame 27 drives the blocking block 29 to slide out from the oil inlet at the top of the oil outlet torque box 26 through the torque rod 19, and the lubricating oil in the oil storage cylinder 24 will flow out into the oil outlet torque box 26 through the oil flow pipe 25, so that the lubricating oil flows to the upper surface of the stainless steel material, so that when the pressing steel roller 11 is bending the stainless steel material, the lubricating oil reduces the friction between the pressing steel roller 11 and the upper surface of the stainless steel material to avoid strain and deformation. By performing lubrication spraying operations on the upper and lower surfaces of the stainless steel material, the friction of the stainless steel material during the bending operation can be reduced, thereby avoiding the phenomenon of wrinkles and strain marks on the stainless steel material during bending. The setting of the oil pipe 236 is to facilitate the oil supply to the oil storage cylinder 24.

[0029] like Figures 7 and 8As shown, a plurality of shafts 30 are fixedly mounted on the outer wall of the oil storage cylinder 24, and the plurality of shafts 30 are respectively slidably connected to the inner walls of the plurality of push rod racks 27, and a plurality of return springs 28 are fixedly mounted between the plurality of push rod racks 27 and the oil storage cylinder 24; When the push rod frame 27 is pressed and moved, the push rod frame 27 squeezes the reset spring 28 and moves on the shaft 30. Through the rotation of the pressure roller 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 reset force of the reset spring 28, the push rod frame 27 is reset, and the blocking block 29 will back-block the oil inlet at the top of the oil outlet torque box 26 to prevent excessive outflow of lubricating oil when the pressure roller 11 rotates to draw the steel and bend the steel, thereby avoiding waste.

[0030] like Figures 6 to 12 As shown, an oil blowing lower plate 15 is fixedly installed at the other end of one side of the power box 6, and 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 opened inside the oil blowing lower plate 15 and the oil blowing upper plate 16, and the through holes are used to connect to an external air source. By connecting an air 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 shell 1, and 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 attached to the stainless steel material. On the one hand, the surface of the stainless steel material can be cleaned, and on the other hand, the lubricating oil can be recovered to avoid unnecessary waste and save resources.

[0031] like Figures 5 to 11 As shown, a return plate wheel 22 is fixedly installed on one side of the oil blowing upper plate 16, a gear 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 gear rod 21, and the teeth on the gear rod 21 mesh with the teeth on the return plate wheel 22; During operation, due to the different bending angles of the stainless steel material, the position where the stainless steel material slides out of the shell 1 will be different. When one end of the stainless steel material slides out of the shell 1, the 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 gear rod 21 to move upward, so that the oil blowing upper plate 16 rotates following the bending degree of the stainless steel material, so that the oil blowing upper plate 16 is always placed on the upper surface of the stainless steel material. When the stainless steel material completely slides out of the shell 1, the oil blowing upper plate 16 loses the thrust of the stainless steel material through the counterweight block 23 set on the bottom end of the gear rod 21, and the oil blowing upper plate 16 will be reset. It should be noted here that the weight of the counterweight block 23 needs to be actually measured and calculated.

[0032] like Figures 3 to 6As shown, the bottom of both sides of the power box 6 are fixedly installed with oil collecting boxes 5, and the oil collecting boxes 5 are placed directly below the steel discharge roller shaft 14 and the steel feed roller shaft 9; During operation, the oil collecting box 5 collects the lubricating oil flowing down in the device. By connecting an oil return device to the oil collecting box 5 and then connecting the oil passing pipe 1 33 and the oil passing pipe 2 36 to the oil return device, the lubricating oil can be recycled.

[0033] Working principle: The stainless steel material to be bent is placed into the shell 1 from the inlet plate port 10, and the steel inlet roller 9 in the shell 1 drives the stainless steel material to move forward. While moving, the lower spray assembly in the steel inlet roller 9 sprays lubricating oil on the lower surface of the stainless steel. Then, the steel inlet roller 9 drives one end of the stainless steel to be placed on the steel outlet roller 14 through the rotation of the steel inlet roller 9, and the stainless steel is placed between the steel inlet roller 9 and the power box 6. Then, the angle adjustment motor 12 is controlled to drive the steel block 13 to move. When the steel block 13 moves to a certain position, the angle formed between the steel block 13, the steel outlet roller 14 and the steel inlet roller 9 is the angle that the stainless steel material needs to be bent. Then, the steel pressing roller 11 is controlled to move downward. When the steel pressing roller 11 contacts the stainless steel material, the upper spray assembly in the steel pressing roller 11 sprays lubricating oil on the upper surface of the stainless steel. Then, the steel pressing roller 11 is controlled to continue to move downward. During the downward movement, the pressure The steel roller 11 squeezes the steel body of the stainless steel material and moves it toward the steel block 13. When the lower surface of the stainless steel material contacts the top of the steel block 13, the steel roller 11 stops moving, and then the steel feed roller 9 and the steel outlet roller 14 continue to be driven to rotate. When the two rotate, they drive the remaining stainless steel material to move into the shell 1. Then, through the limited extrusion pressure of the steel roller 11, the stainless steel material will bend to a specified angle, thereby realizing the bending operation of the stainless steel material. When the stainless steel material moves in the shell 1, the upper spraying component in the steel roller 11 sprays lubricating oil on the upper surface of the stainless steel material to reduce the friction between the steel roller 11 and the upper surface of the stainless steel material. The lower spraying component in the steel feed roller 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 block 13. The two cooperate with each other to reduce the friction of the stainless steel material during bending, thereby avoiding strain and deformation. The driving wheel motor 35 drives the driving wheel 18 to rotate. When the driving wheel 18 rotates, the gear meshing drives the transmission wheel 20 to rotate, thereby driving the steel feeding roller 9 and the steel discharging roller 14 to rotate, so as to pull the stainless steel material. By pulling and bending the stainless steel material, the device can be applied to stainless steel materials of different lengths. By controlling the operation of the driving wheel motor 35, the steel discharging roller 14 and the steel feeding roller 9 can be rotated and stopped. By symmetrically opening two workstations in the device, the bending efficiency of the stainless steel material can be accelerated during the bending operation, which is more conducive to the operation. By controlling the hydraulic cylinder 2 to drive the connecting frame 17 to move, the position of the pressing steel roller 11 can be moved, so that when the stainless steel material is placed between the steel inlet roller 9 and the steel outlet roller 14, the pressing steel roller 11 can squeeze the stainless steel material for bending. By squeezing and bending the stainless steel material with the pressing steel roller 11, the device can be applied to stainless steel materials of different thicknesses. When the stainless steel material is put into the housing 1, the sliding rod 7 is driven to move by controlling the telescopic cylinder 8, and 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 telescopic cylinder 8 stops moving the sliding rod 7. At this time, the sliding rod 7 performs a limit block on the stainless steel material to prevent the stainless steel material from running out from between the steel output roller 14 and the steel input roller 9 due to the excessive squeezing force of the steel pressing roller 11 when the stainless steel material is bent. At the same time, the sliding rod 7 performs a limit block on the stainless steel material, and the device can also be applied to stainless steel materials of different widths. By connecting an air intake assembly to the vent pipe 32, when the steel feed roller 9 rotates to drive the stainless steel material to move, the gas in the vent pipe 32 pushes the oil push plate 34 in the oil storage box 31 to move upward, and the oil push plate 34 pushes the lubricating oil in the oil storage box 31 to move upward when moving upward. Through the steel feed roller 9 and the leakage on the oil storage box 31, when the steel feed roller 9 drives the stainless steel material to move, the oil push plate 34 pushes the lubricating oil in the oil storage box 31 to flow from the leakage to the bottom of the stainless steel material, so as to spray the lubricating oil on the lower surface of the stainless steel material, thereby reducing the friction between the stainless steel material and the steel block 13 when bending, avoiding strain and deformation. The setting of the oil pipe 33 is to facilitate the oil inlet into the oil storage cylinder 24; When the pressing steel roller 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 pressing steel roller 11 to move upward. When the pushing rod frame 27 moves upward, it drives the blocking block 29 to slide out from the oil inlet at the top of the oil outlet torque box 26 through the torque rod 19, and the lubricating oil in the oil storage cylinder 24 will flow out into the oil outlet torque box 26 through the oil flow pipe 25, so that the lubricating oil flows to the upper surface of the stainless steel material, so that when the pressing steel roller 11 is bending the stainless steel material, the lubricating oil reduces the friction between the pressing steel roller 11 and the upper surface of the stainless steel material, avoiding strain and deformation. By performing lubrication spraying on the upper and lower surfaces of the stainless steel material, the friction of the stainless steel material during the bending operation can be reduced, thereby avoiding the phenomenon of wrinkles and strain marks on the stainless steel material during bending. The setting of the oil pipe 236 is to facilitate the oil inlet into the oil storage cylinder 24; When the push rod frame 27 is pressed and moved, the push rod frame 27 squeezes the return spring 28 to move on the shaft 30. Through the rotation of the pressing steel roller 11, when the push rod frame 27 loses the limiting thrust on the upper surface of the stainless steel material, the push rod frame 27 is reset under the action of the elastic return force of the return spring 28, and the block 29 will back-block the oil inlet at the top of the oil outlet torque box 26 to prevent excessive outflow of lubricating oil when the pressing steel roller 11 rotates to draw the steel and bend the steel, thereby avoiding waste. By connecting an air 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 shell 1, and 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 attached to the stainless steel material. On the one hand, the surface of the stainless steel material can be cleaned, and on the other hand, the lubricating oil can be recovered to avoid unnecessary waste and save resources. Due to the different bending angles of the stainless steel material, the position where the stainless steel material slides out of the shell 1 will be different. When one end of the stainless steel material slides out of the shell 1, the 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 gear rod 21 to move upward, so that the oil blowing upper plate 16 rotates along with the bending degree of the stainless steel material, so that the oil blowing upper plate 16 is always placed on the upper surface of the stainless steel material. When the stainless steel material completely slides out of the shell 1, the oil blowing upper plate 16 loses the thrust of the stainless steel material through the counterweight block 23 set at the bottom end of the gear rod 21, and the oil blowing upper plate 16 will be reset; The oil collecting box 5 collects the lubricating oil flowing down in the device. By connecting an oil return device to the oil collecting box 5 and then connecting the oil passing pipe 1 33 and the oil passing pipe 2 36 to the oil return device, the lubricating oil can be recycled.
