Description

Technical Field

[0001] This invention belongs to the field of stainless steel round bar processing technology, specifically a bending and cutting device for processing stainless steel round bars. Background Technology

[0002] When bending stainless steel round bars, a rotating bending disc operates synchronously, working in conjunction with the bar to bend it into a preset workpiece shape. After bending, a cutting device separates the workpiece from the continuously conveying bar, thus completing the initial processing. Workpiece preparation is then complete.

[0003] A patent with publication number CN120663141B discloses a bending and cutting device for processing stainless steel round bars, including a conveying processing component, an upper abutment component, a bending component, a conveying limiting block, and a base plate. An adjustable auxiliary component is installed on one side of the conveying limiting block. The adjustable auxiliary component includes a fixed plate fixedly installed above the base plate and a movable plate movably installed above the base plate. Driven by a telescopic component, the lower inclined plate pushes the movable abutment block. That is, the two movable abutment blocks abut against the round bar inside the movable abutment block through an arc-shaped block to position it. As the cutting blade continues to descend with the top plate, it cuts the connection between the round bar and the workpiece. After the cutting work is completed, the telescopic component is driven to make the top plate rise. The movable plate moves away from the fixed plate, widening the distance between the two. The movable grinding component allows the grinding structure to enter the distance between the fixed plate and the movable plate, and grinds the cut surface of the round bar and the workpiece.

[0004] However, existing bending and cutting equipment for processing stainless steel round bars has obvious defects in use. In the grinding stage, it only relies on the grinding disc to grind the uneven end face of the cut surface. However, after the stainless steel round bar is cut, not only does the end face need to be ground, but there are often a lot of burrs on the arc surface of the end face. The existing equipment lacks an effective grinding function for these arc surface burrs. As a result, when the workers collect the processed workpieces, these sharp burrs can easily injure the workers' hands, posing a safety hazard. In addition, a lot of metal dust is generated during the grinding process. The existing equipment is not equipped with a complete dust collection device, which allows the metal dust to be scattered in the working environment, seriously polluting the working environment.

[0005] Therefore, the present invention provides a bending and cutting device for processing stainless steel round bars. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A bending and cutting device for processing stainless steel round bars, comprising a machine body, a conveying pipe fixedly connected to the upper surface of the machine body for conveying stainless steel round bars, a fixed platform fixedly connected to the upper surface of the machine body, a fixed plate fixedly connected to the upper surface of the fixed platform, a first hydraulic cylinder fixedly connected to the upper surface of the fixed plate, a cutting blade provided at the output end of the first hydraulic cylinder, a positioning plate fixedly connected to the upper surface of the machine body, two rotating blocks rotatably connected to the upper surface of the positioning plate, and a... The system includes a processing component comprising a first guide rail formed on the upper surface of the machine body, two first guide plates slidably connected within the first guide rail, the two first guide plates being symmetrically arranged, a fixed frame fixedly connected to the end of one of the first guide plates, a driving component disposed within the fixed frame, an arc-shaped plate fixedly connected to one side of the fixed frame, a fixed groove formed inside the arc-shaped plate, a gear disk rotatably connected inside the fixed groove, the gear disk being used to grind the end faces of two stainless steel round bars, and a cleaning component disposed at the end of the other first guide plate to assist the processing component in its grinding operation. Grinding columns are fixed to both sides of the gear disk. An annular groove is opened on the arc plate corresponding to the position of the grinding column. The grinding column rotates in the annular groove and grinds the arc surface of the end of the stainless steel plate. An auxiliary plate is fixedly attached to the upper surface of the machine body, and a third hydraulic cylinder is fixedly attached to the upper surface of the auxiliary plate. A limit block is fixedly attached to the output end of the third hydraulic cylinder.

[0008] Preferably, the drive plate includes a fixed motor fixedly connected to one side of the fixed frame, and a fixed gear is fixedly connected to the output end of the fixed motor, the fixed gear meshing with the gear disk.

[0009] Preferably, the arc-shaped plate has a plurality of positioning grooves inside, a second hydraulic cylinder is fixedly connected in the positioning groove, a positioning block is fixedly connected to the output end of the second hydraulic cylinder, and a positioning plate is elastically connected inside the positioning block.

[0010] Preferably, a connecting groove is provided on one side of the positioning block, a spring is fixedly connected to the inner wall of the connecting groove, a positioning plate is fixedly connected to one end of the spring, and several rubber strips are fixedly connected to the surface of the positioning plate.

[0011] Preferably, one end of the first guide plate is fixedly connected to a connecting frame, and a cleaning component is provided inside the connecting frame. The cleaning component includes a fixing box fixedly connected to the side of the first guide plate, and a plurality of spray pipes are fixedly connected to one end of the fixing box. The spray pipes are used to spray coolant.

[0012] Preferably, the connecting frame has an inclined groove inside, and a plurality of fixing holes are provided at one end of the inclined groove. The first guide plate is provided with a collection component at the position corresponding to the fixing holes. The collection component is used to collect metal dust carried by the coolant.

[0013] Preferably, the collection component includes hooks fixed to both sides of the first guide plate, and two hooks are engaged with the same collection box, the collection box having a collection slot.

[0014] Preferably, when performing the bending and cutting of stainless steel round bars, the stainless steel round bars are first conveyed to the positioning plate by the conveying pipe. At this time, the stainless steel round bars pass between the two rotating blocks on the positioning plate. Then, the third hydraulic cylinder on the upper surface of the auxiliary plate is activated. After the third hydraulic cylinder is activated, the limiting block at its output end moves down. After the limiting block moves down, it abuts against the stainless steel round bar, thereby limiting the stainless steel round bar. Then, the positioning plate is activated, and the two rotating blocks on its upper surface rotate. The rotation of the rotating blocks bends the stainless steel round bar. After bending is completed, the first hydraulic cylinder on the upper surface of the fixing plate is activated. The first hydraulic cylinder drives the cutting blade at its output end to cut the stainless steel round bar. After the stainless steel round bar is cut, the bent section is separated from the stainless steel round bar by a certain distance. This distance is the width of the cutting blade. Then, the processing component on the upper surface of the machine body is activated. The first guide rail on the upper surface of the machine body is activated first. The two first guide plates in the first guide rail move closer to the stainless steel round bars. The processing component is set at the end of one of the first guide plates, and the cleaning component is set at the end of the other guide plate. The two first guide plates drive their respective arc plates to abut against the stainless steel round bars. Then, the driving component is activated, specifically the fixed motor is activated. The fixed motor drives the fixed gear to rotate. The fixed gear drives the gear disk meshing with it in the arc plate. The rotation of the gear disk grinds the end faces of the two stainless steel round bars. In addition, there is a grinding column on the side of the gear disk. The grinding column rotates along the annular groove with the gear disk to grind the arc surface of the end of the stainless steel round bars.

[0015] Preferably, after the gear disk is inserted between the two stainless steel round bars, that is, after both arc plates abut against the stainless steel round bars, the second hydraulic cylinders at both ends of each arc plate are activated. The second hydraulic cylinders retract the positioning blocks at their output ends. As the arc plates approach the stainless steel round bars, the second hydraulic cylinders drive the positioning blocks at their output ends to move outwards from the arc plates, and then abut against the arc plates. The positioning blocks are then driven to retract. During the retraction of the positioning blocks, the electro-permanent magnets on their inner walls are energized, repelling the positioning plates inside. The friction strips on the surface of the positioning plates are in close contact with the stainless steel round bars. Then, the retraction action of the positioning blocks pulls the two stainless steel round bars closer to the gear disk, assisting the gear disk in the grinding work.

[0016] Preferably, while the gear disk is being polished, the cleaning component on another first guide plate is also working simultaneously. The other first guide plate is a fixed box on the surface. Under the action of the built-in pressure pump, the coolant inside is pressurized and sprayed out from the nozzle at the end of the fixed box. The nozzle is set at an angle and faces the gear tooth surface of the gear disk. The coolant that is washed down will flow into the fixed hole along the inclined groove on the bottom wall of the connecting frame, and then flow into the collection box that is snapped into the side of the first guide plate through the fixed hole for unified collection.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a bending and cutting device for processing stainless steel round bars. Through the cooperation of a conveying pipe, a positioning plate, and a limiting block, the round bar is positioned to ensure bending stability. The positioning plate drives the rotating block to rotate, achieving efficient bending. A first hydraulic cylinder drives the cutting blade to complete the cutting. Subsequent processing components and cleaning components work together, using a first guide rail and a first guide plate to approach the round bar. A fixed motor drives a gear disk, which not only grinds the end face of the round bar, but the grinding column can also rotate along the annular groove to grind the arc surface. This effectively improves the processing accuracy and surface quality of the round bar, reduces subsequent processing steps, and increases production efficiency and product qualification rate.

[0018] 2. The bending and cutting device for processing stainless steel round bars according to the present invention, after the gear disk is positioned and the arc plate abuts against the round bar, the second hydraulic cylinder first drives the positioning block to move outward and then retracts it. The permanent magnet is energized, and the magnetic repulsion makes the friction strip on the positioning plate tightly adhere to the round bar. This not only stabilizes the position of the round bar and prevents it from shaking during grinding, but also increases the contact friction through the friction strip. The retraction of the positioning block pulls the round bar closer to the gear disk, making the round bar fit more tightly with the grinding parts. This provides powerful assistance for the precise grinding of the gear disk, effectively improves the grinding effect and efficiency, ensures the grinding quality of the end face and arc surface of the stainless steel round bar, and reduces the defect rate.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

A fixed platform 2 is also fixedly connected to the upper surface of the machine body 1, and a fixed plate 21 is fixedly connected to the upper surface of the fixed platform 2. A first hydraulic cylinder 22 is fixedly connected to the upper surface of the fixed plate 21, and a cutting blade is provided at the output end of the first hydraulic cylinder 22. A positioning disk 5 is fixedly connected to the upper surface of the machine body 1, and two rotating blocks 51 are rotatably connected to the upper surface of the positioning disk 5. A processing component is provided on the upper surface of the machine body 1, including a first guide rail 3 formed on the upper surface of the machine body 1. Two first guide plates 31 are slidably connected within the first guide rail 3, and the two first guide plates 31 are symmetrically arranged. A fixed frame 32 is fixedly connected to the end of one of the first guide plates 31, and a driving component is provided within the fixed frame 32. An arc-shaped... Plate 33, the inside of which is an arc-shaped plate 33 has a fixed groove 35. A gear disk 36 is rotatably connected inside the fixed groove 35. The gear disk 36 is used to grind the end faces of two stainless steel round bars. The end of another first guide plate 31 is provided with a cleaning component to assist the processing component in the grinding work. Grinding columns 37 are fixedly connected to both sides of the gear disk 36. The arc-shaped plate 33 has an annular groove 38 corresponding to the position of the grinding column 37. The grinding column 37 rotates in the annular groove 38 and grinds the arc surface of the end of the stainless steel plate. An auxiliary plate 4 is fixedly connected to the upper surface of the machine body 1. A third hydraulic cylinder 41 is fixedly connected to the upper surface of the auxiliary plate 4. A limit block 42 is fixedly connected to the output end of the third hydraulic cylinder 41. The drive plate includes a fixed motor 34 fixedly connected to one side of the fixed frame 32. A fixed gear 313 is fixedly connected to the output end of the fixed motor 34. The fixed gear 313 meshes with the gear disk 36.

[0023] Specifically, existing bending and cutting equipment for processing stainless steel round bars has obvious defects in use. In the grinding stage, it only relies on the grinding disc to grind the uneven end face of the cut surface. However, after the stainless steel round bar is cut, not only does the end face need to be ground, but there are often a lot of burrs on the arc surface of the end face. The existing equipment lacks an effective grinding function for these arc surface burrs. As a result, when the workers collect the processed workpieces, these sharp burrs can easily injure the workers' hands, posing a safety hazard. In addition, a lot of metal dust is generated during the grinding process. The existing equipment is not equipped with a complete dust collection device, which allows the metal dust to be scattered in the working environment, seriously polluting the working environment. Therefore, the present invention solves the above problems by setting the above structure. First, when the stainless steel round bar is bent and cut, the stainless steel round bar is first conveyed to the positioning plate 5 by the conveying pipe 11. At this time, the stainless steel round bar passes between the two rotating blocks 51 on the positioning plate 5. Then, the third hydraulic cylinder 41 on the upper surface of the auxiliary plate 4 is activated. After the third hydraulic cylinder 41 is activated, the limiting block 42 at its output end is driven to move down. After the limiting block 42 moves down, it will abut against the stainless steel round bar, thereby limiting the stainless steel round bar. Then, the positioning plate 5 is activated, and the positioning plate 5 drives the two rotating blocks 51 on its upper surface to rotate. The rotation of the rotating blocks 51 bends the stainless steel round bar. After the bending is completed, the first hydraulic cylinder 22 on the upper surface of the fixing plate 21 is activated. The first hydraulic cylinder 22 drives the cutting blade at its output end to cut the stainless steel round bar. After the stainless steel round bar is cut, the bent part is separated from the stainless steel round bar. After a certain distance, which is the width of the cutting blade, the processing component on the upper surface of the machine body 1 is activated. The first guide rail 3 on the upper surface of the machine body 1 is activated first. The two first guide plates 31 in the first guide rail 3 approach the stainless steel round bar. The processing component is set at the end of one of the first guide plates 31, and the cleaning component is set at the end of the other guide plate. The two first guide plates 31 drive their respective arc plates 33 to abut against the stainless steel round bar. Then the driving component is activated, specifically the fixed motor 34 is activated. The fixed motor 34 drives the fixed gear 313 to rotate. The fixed gear 313 drives the gear disk 36 meshing with it in the arc plate 33. The rotation of the gear disk 36 grinds the end faces of the two stainless steel round bars. In addition, the side of the gear disk 36 is also provided with a grinding column 37. The grinding column 37 rotates along the annular groove 38 as the gear disk 36 rotates, and grinds the arc surface of the end of the stainless steel round bar. The round bar is positioned by the cooperation of the conveying pipe 11, the positioning plate 5 and the limiting block 42 to ensure bending stability. The positioning plate 5 drives the rotating block 51 to rotate, achieving efficient bending. The first hydraulic cylinder 22 drives the cutting blade to complete the cutting. The subsequent processing components and cleaning components work together to approach the round bar with the help of the first guide rail 3 and the first guide plate 31. The fixed motor 34 drives the gear disk 36 to not only grind the end face of the round bar, but the grinding column 37 can also rotate along the annular groove 38 to grind the arc surface, effectively improving the processing accuracy and surface quality of the round bar, reducing subsequent processing steps, and improving production efficiency and product qualification rate.

[0024] Example 2: Figures 1 to 8As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the interior of the arc plate 33 is provided with a plurality of positioning grooves 39, a second hydraulic cylinder 310 is fixedly connected in the positioning grooves 39, a positioning block 311 is fixedly connected to the output end of the second hydraulic cylinder 310, a positioning plate 312 is elastically connected inside the positioning block 311, a connecting groove 314 is provided on one side of the positioning block 311, a spring 315 is fixedly connected to the inner wall of the connecting groove 314, a positioning plate 312 is fixedly connected to one end of the spring 315, and a plurality of rubber strips 316 are fixedly connected to the surface of the positioning plate 312.

[0025] Specifically, after the gear disk 36 is inserted between the two stainless steel round bars, that is, after both arc plates 33 are in contact with the stainless steel round bars, the second hydraulic cylinders 310 at both ends of each arc plate 33 are activated. The second hydraulic cylinders 310 retract the positioning blocks 311 at their output ends. As the arc plates 33 approach the stainless steel round bars, the second hydraulic cylinders 310 drive the positioning blocks 311 at their output ends to move outward from the arc plates 33. After contacting the arc plates 33, the positioning blocks 311 are driven to retract. During the retraction of the positioning blocks 311, the electro-permanent magnets on their inner walls are energized, repelling the positioning plates 312 inside. The friction strips on the surface of the positioning plates 312 are in close contact with the stainless steel round bars. Then, the retraction action of the positioning blocks 311 pulls the two stainless steel round bars closer to the gear disk 36, assisting the gear disk 36 in performing the grinding work. After the gear disk 36 is in place and the arc plate 33 abuts against the round bar, the second hydraulic cylinder 310 first drives the positioning block 311 to move outward and then retracts. The permanent magnet is energized, and the magnetic force repulsion makes the friction strip on the positioning plate 312 stick tightly to the round bar. This not only stabilizes the position of the round bar and prevents it from shaking during grinding, but also increases the contact friction through the friction strip. The positioning block 311 retracts and pulls the round bar closer to the gear disk 36, making the round bar fit more tightly with the grinding parts. This provides powerful assistance for the precise grinding of the gear disk 36, effectively improves the grinding effect and efficiency, ensures the grinding quality of the end face and arc surface of the stainless steel round bar, and reduces the defect rate.

[0026] like Figure 8 As shown, in this embodiment, one end of the first guide plate 31 is fixedly connected to a connecting frame 318. A cleaning component is provided inside the connecting frame 318. The cleaning component includes a fixing box 317 fixedly connected to the side of the first guide plate 31. One end of the fixing box 317 is fixedly connected to several nozzles 321. The nozzles 321 are used to spray coolant. An inclined groove 322 is opened inside the connecting frame 318. One end of the inclined groove 322 is opened to several fixing holes 323. A collection component is provided on the first guide plate 31 at the position corresponding to the fixing holes 323. The collection component is used to collect metal dust carried by the coolant. The collection component includes hooks 319 fixedly connected to both sides of the first guide plate 31. Two hooks 319 are engaged with the same collection box 320. A collection groove 324 is opened inside the collection box 320.

[0027] Specifically, while the gear disk 36 is being polished, the cleaning components on another first guide plate 31 are also working. The fixed box 317 on the surface of the other first guide plate 31 is pressurized by the built-in pressure pump and sprayed out from the nozzle 321 at the end of the fixed box 317. The nozzle 321 is inclined and faces the gear tooth surface of the gear disk 36. The coolant that is washed down will flow into the fixed hole 323 along the inclined groove 322 on the bottom wall of the connecting frame 318, and then flow into the collection box 320 that is snapped into the side of the first guide plate 31 for unified collection. During the grinding of the gear disk 36, the pressure pump in the fixed box 317 pressurizes the coolant, which is then sprayed from the inclined nozzle 321 onto the gear tooth surface. This not only cools the grinding area in time, preventing the gear disk 36 from being affected by high temperature and extending the tool's service life, but also washes away the metal dust generated during grinding, ensuring grinding accuracy. Furthermore, the coolant can flow into the collection box 320 along the inclined groove 322 and the fixed hole 323 for unified collection, avoiding splashing and facilitating subsequent processing and recycling, making it green and environmentally friendly.

[0028] Working principle: First, when bending and cutting stainless steel round bars, the stainless steel round bars are first conveyed to the positioning plate 5 by the conveying pipe 11. At this time, the stainless steel round bars pass between the two rotating blocks 51 on the positioning plate 5. Then, the third hydraulic cylinder 41 on the upper surface of the auxiliary plate 4 is activated. After the third hydraulic cylinder 41 is activated, it drives the limiting block 42 at its output end to move down. After the limiting block 42 moves down, it will abut against the stainless steel round bar, thereby limiting the stainless steel round bar. Then, the positioning plate 5 is activated, and the two rotating blocks 51 on its upper surface are driven to rotate. The rotation of the rotating blocks 51 bends the stainless steel round bar. After bending is completed, the first hydraulic cylinder 22 on the upper surface of the fixing plate 21 is activated. The first hydraulic cylinder 22 drives the cutting blade at its output end to cut the stainless steel round bar. After the stainless steel round bar is cut, the bent part is separated from the stainless steel round bar by a certain distance. To cut the width of the blade, the processing components on the upper surface of the machine body 1 are then activated. The first guide rail 3 on the upper surface of the machine body 1 is activated first. The two first guide plates 31 in the first guide rail 3 move closer to the stainless steel round bar. The processing component is set at the end of one of the first guide plates 31, and the cleaning component is set at the end of the other guide plate. The two first guide plates 31 drive their respective arc plates 33 to abut against the stainless steel round bar. Then the driving component is activated, specifically the fixed motor 34 is activated. The fixed motor 34 drives the fixed gear 313 to rotate. The fixed gear 313 drives the gear disk 36 meshing with it in the arc plate 33. The rotation of the gear disk 36 grinds the end faces of the two stainless steel round bars. In addition, the side of the gear disk 36 is also provided with a grinding column 37. The grinding column 37 rotates along the annular groove 38 as the gear disk 36 rotates, and grinds the arc surface of the end of the stainless steel round bar. The round bar is positioned by the cooperation of the conveying pipe 11, the positioning plate 5 and the limiting block 42 to ensure bending stability. The positioning plate 5 drives the rotating block 51 to rotate, achieving efficient bending. The first hydraulic cylinder 22 drives the cutting blade to complete the cutting. The subsequent processing components and the cleaning components work together to approach the round bar with the help of the first guide rail 3 and the first guide plate 31. The fixed motor 34 drives the gear disk 36 to not only grind the end face of the round bar, but the grinding column 37 can also rotate along the annular groove 38 to grind the arc surface, effectively improving the processing accuracy and surface quality of the round bar, reducing subsequent processing steps, and improving production efficiency and product qualification rate. After the gear disk 36 is inserted between the two stainless steel round bars, that is, after both arc plates 33 abut against the stainless steel round bars, the second hydraulic cylinders 310 at both ends of each arc plate 33 are activated. The second hydraulic cylinders 310 retract the positioning blocks 311 at their output ends. As the arc plates 33 approach the stainless steel round bars, the second hydraulic cylinders 310 drive the positioning blocks 311 at their output ends to move outward from the arc plates 33, and then abut against the arc plates 33. Then, the positioning blocks 311 are driven to retract. During the retraction of the positioning blocks 311, the electro-permanent magnets on their inner walls are energized, repelling the positioning plates 312 inside. The friction strips on the surface of the positioning plates 312 are in close contact with the stainless steel round bars. Then, the retraction action of the positioning blocks 311 pulls the two stainless steel round bars closer to the gear disk 36, assisting the gear disk 36 in the grinding work. After the gear disk 36 is in place and the arc plate 33 abuts against the round bar, the second hydraulic cylinder 310 first drives the positioning block 311 to move outward and then retracts. The permanent magnet is energized, and the magnetic force repulsion makes the friction strip on the positioning plate 312 stick tightly to the round bar. This not only stabilizes the position of the round bar and prevents it from shaking during grinding, but also increases the contact friction through the friction strip. The positioning block 311 retracts and pulls the round bar closer to the gear disk 36, making the round bar fit more tightly with the grinding parts. This provides a powerful assistance for the precise grinding of the gear disk 36, effectively improves the grinding effect and efficiency, ensures the grinding quality of the end face and arc surface of the stainless steel round bar, and reduces the defect rate. In addition, while the gear disk 36 is being polished, the cleaning component on another first guide plate 31 is also working. The fixed box 317 on the surface of the other first guide plate 31 is pressurized by the built-in pressure pump and sprayed out from the nozzle 321 at the end of the fixed box 317. The nozzle 321 is set at an angle and faces the tooth surface of the gear disk 36. The coolant that is washed down will flow into the fixed hole 323 along the inclined groove 322 on the bottom wall of the connecting frame 318, and then flow into the collection box 320 that is snapped into the side of the first guide plate 31 for unified collection. During the grinding of the gear disk 36, the pressure pump in the fixed box 317 pressurizes the coolant, which is then sprayed from the inclined nozzle 321 onto the gear tooth surface. This not only cools the grinding area in time, preventing the gear disk 36 from being affected by high temperature and extending the tool's service life, but also washes away the metal dust generated during grinding, ensuring grinding accuracy. Furthermore, the coolant can flow into the collection box 320 along the inclined groove 322 and the fixed hole 323 for unified collection, avoiding splashing and facilitating subsequent processing and recycling, making it green and environmentally friendly.

8. A bending and cutting device for processing stainless steel round bars according to claim 2, characterized in that: When performing the bending and cutting of stainless steel round bars, the stainless steel round bars are first conveyed to the positioning plate (5) by the conveying pipe (11). At this time, the stainless steel round bars pass between the two rotating blocks (51) on the positioning plate (5). Then, the third hydraulic cylinder (41) on the upper surface of the auxiliary plate (4) is activated. After the third hydraulic cylinder (41) is activated, the limiting block (42) at its output end is driven to move down. After the limiting block (42) moves down, it will abut against the stainless steel round bars, thereby limiting the stainless steel round bars. Then, the positioning plate (5) is activated. The positioning plate (5) drives the two rotating blocks (51) on its upper surface to rotate. The rotation of the rotating blocks (51) bends the stainless steel round bars. After the bending is completed, the first hydraulic cylinder (22) on the upper surface of the fixing plate (21) is activated. The first hydraulic cylinder (22) drives the cutting blade at its output end to cut the stainless steel round bars. After the stainless steel round bars are cut, the bent part is separated from the stainless steel round bars by a distance, which is the width of the cutting blade. Then, the processing components on the upper surface of the machine body (1) are started. The first guide rail (3) on the upper surface of the machine body (1) is started first. The two first guide plates (31) in the first guide rail (3) move closer to the stainless steel round bar. One of the first guide plates (31) is equipped with a processing component at its end, and the other guide plate is equipped with a cleaning component at its end. The two first guide plates (31) drive their respective arc plates (33) to abut against the stainless steel round bar. Then, the driving component is started, specifically the fixed motor (34) is started. The fixed motor (34) drives the fixed gear (313) to rotate. The fixed gear (313) drives the gear disk (36) meshing with it in the arc plate (33). The rotation of the gear disk (36) grinds the end faces of the two stainless steel round bars. In addition, a grinding column (37) is also provided on the side of the gear disk (36).

The second hydraulic cylinder (310) retracts the positioning block (311) at its output end. During the process of the arc plate (33) approaching the stainless steel round bars, the second hydraulic cylinder (310) drives the positioning block (311) at its output end to move to the outside of the arc plate (33), and then in contact with the arc plate (33), and then drives the positioning block (311) to retract. During the retraction of the positioning block (311), the electro-permanent magnet block on its inner wall is energized, which repels the positioning plate (312) inside. The friction strip on the surface of the positioning plate (312) is in close contact with the stainless steel round bars. Then the retraction action of the positioning block (311) pulls the two stainless steel round bars close to the gear disk (36) to assist the gear disk (36) in the grinding work.

10.
