Description

Technical Field

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

[0002] In the processing industry of metal materials, stainless steel products are widely used due to their excellent corrosion resistance and aesthetics. During the processing of stainless steel pipes, burrs, defects or irregular shapes may occur at the edges. These edge defects not only affect the appearance but also may pose safety hazards such as scratches and cuts during use. Therefore, edge trimming is carried out during the processing of stainless steel pipes.

[0003] A patent application with the publication number CN119159386A discloses a trimming device for processing stainless steel products, including a chassis. On the left and right sides of the chassis, a first conveyor belt and a second conveyor belt are respectively arranged. A flying shear device and a rotary shear device are respectively arranged on the left and right sides of the chassis where the second conveyor belt is located. And the first conveyor belt includes four conveyor belts arranged in a square matrix. Through the continuous operation of the rotary shear device and the flying shear device, this device reduces the pause time during the trimming process, improves the continuity and overall efficiency of the production process, and effectively removes the burrs on the edges of the trimmed stainless steel plate by equipping with a grinding component, improves the product quality, and reduces the safety risks during the subsequent processing.

[0004] The above solution still has some problems in actual application. When using the above device to trim the edges of stainless steel pipes, since both ends of the stainless steel pipe need to be processed, and the existing device fixes the stainless steel pipe by clamping the ends of the stainless steel pipe during edge trimming, this method will separate the edge trimming work at both ends of the stainless steel pipe. While clamping one end, the edge trimming work of the other end is carried out, and then switched to complete the edge trimming work at both ends, thus reducing the edge trimming efficiency. And when the edge trimming of one end of the stainless steel pipe is completed and switched to fix the other end, the position of the stainless steel pipe and the cutting tool needs to be repositioned. If the positioning is inaccurate, it will also reduce the processing accuracy and affect the edge trimming quality.

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

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Example 1: As Figures 1 to 13As shown in the figure, a trimming device for stainless steel profiles according to an embodiment of the present invention includes a base frame 1. A conveying structure 3 is provided at the upper end of the base frame 1. The conveying structure 3 includes a placement plate 31. The placement plate 31 is provided at the upper end of the base frame 1, and a placement groove 33 is formed on the surface of the placement plate 31. Transfer plates 32 are slidably connected to both ends of the placement plate 31. Two first rotating plates 34 are provided at the lower ends of the transfer plates 32. Two second rotating plates 35 are rotatably connected inside the base frame 1, and the eccentric parts of the second rotating plates 35 are connected to the eccentric parts of the first rotating plates 34; Trimming structures 4 are provided on both sides of the placement plate 31, and an adjusting structure 6 is provided at one end of the trimming structure 4 close to the placement plate 31; The adjusting structure 6 includes: a fixed frame 601, and the fixed frame 601 is provided at one end of the upper end of the base frame 1 close to the placement plate 31; Fixed blocks 610, and two fixed blocks 610 are slidably connected to one end of the fixed frame 601; The trimming structure 4 includes: cylinders 41, and two cylinders 41 are provided at the upper end of the base frame 1, A sliding block 43, the sliding block 43 is provided at the end of the cylinder 41, and the cylinder 41 is connected to the sliding block 43; An operation disk 46, and the operation disk 46 is rotatably connected to one end of the fixed frame 601; A cutting tool 45, and the cutting tool 45 is rotatably connected to the surface of the operation disk 46, and the operation disk 46 is used to control the cutting tool 45; A drive shaft 44, and the drive shaft 44 is provided on the surface of the operation disk 46, and the drive shaft 44 is connected to the eccentric part of the cutting tool 45.

[0023] Specifically, a trimming device for stainless steel profiles of this solution is mainly used for trimming stainless steel pipes 5. During use, first transfer the stainless steel pipe 5 to the placement groove 33 on the surface of the placement plate 31. At this time, both ends of the stainless steel pipe 5 are located inside the transfer plate 32. Then start the second rotating plate 35 to rotate. Since the eccentric part of the second rotating plate 35 is connected to the eccentric part of the first rotating plate 34, the first rotating plate 34 will drive the transfer plate 32 to rotate at this time, thereby transferring the stainless steel pipe 5 inside the placement groove 33. When the stainless steel pipe 5 is transferred to the same vertical line as the fixed frame 601, start the cylinder 41. The cylinder 41 will drive the fixed frame 601 to move towards the inside of the stainless steel pipe 5 through the sliding block 43. When the end of the fixed frame 601 moves inside the stainless steel pipe 5, start the fixed block 610. The two fixed blocks 610 will move towards the upper and lower ends respectively and finally move to abut against the inner wall of the stainless steel pipe 5, thus completing the fixation of the stainless steel pipe 5. Then start the operation panel 46. The operation panel 46 will supply electric energy to the cutting knife 45, causing the cutting knife 45 to rotate. And at this time, start the drive shaft 44 to rotate. Since the drive shaft 44 is connected to the eccentric part of the cutting knife 45, the cutting knife 45 will rotate around the drive shaft 44 while rotating itself at this time, and then trim the stainless steel pipe 5 from the inside of the stainless steel pipe 5. The transfer plate 32 of this device can continuously transfer the stainless steel pipe 5, so that the trimming work can be carried out continuously. And the adjustment structure 6 can also trim both ends of the stainless steel pipe 5 at the same time when the stainless steel pipe 5 is fixed. And since the trimming work is carried out inside the stainless steel pipe 5, the outer layer of the stainless steel pipe 5 can be protected from wear.

[0024] As Figures 1 to 9 shown, the adjustment structure 6 further includes: a rotating circular plate 602, which is rotatably connected to one end of the fixed frame 601; a moving groove 608, which is opened on the surface of the rotating circular plate 602; a lifting block 615, which is slidably connected to the surface of the fixed frame 601 up and down, and the lifting block 615 is connected to the fixed block 610; a moving bar 609, which is arranged at one end of the lifting block 615, and the moving bar 609 slides on the inner wall of the moving groove 608. The trimming structure 4 further includes: a slide rail 42, which is arranged at the upper end of the base frame 1, and the sliding block 43 slides on the surface of the slide rail 42.

[0025] Specifically, when the end of the fixed frame 601 moves into the interior of the stainless steel pipe 5, the rotating circular plate 602 is started to rotate. While the rotating circular plate 602 is rotating, the two moving bars 609 will move along the inner wall of the moving groove 608. Since the moving bar 609 can only move up and down with the lifting block 615, the fixed block 610 will also move vertically towards the upper and lower ends at this time. Since the fixed block 610 has moved into the interior of the stainless steel pipe 5 at this time, the fixing of the stainless steel pipe 5 is completed at this time.

[0026] As Figures 1 to 10 shown, a first screw rod 618 is provided inside the rotating circular plate 602, and the first screw rod 618 passes through the fixed frame 601 and the operation disk 46. An abutting piece 603 is provided at one end of the first screw rod 618 close to the placing plate 31. The other end of the first screw rod 618 is rotatably connected to a connecting column 621. A fixed cylinder 619 is provided at one end of the sliding block 43 close to the fixed frame 601, and the first screw rod 618 and the connecting column 621 slide inside the fixed cylinder 619. A thread groove 620 is opened inside the fixed cylinder 619, and the first screw rod 618 is threadedly connected to the thread groove 620. A return spring 622 is provided at one end of the connecting column 621, and the other end of the return spring 622 is connected to the inner wall of the fixed cylinder 619.

[0027] Specifically, when performing the edge cutting treatment on the stainless steel pipe 5, the two fixed frames 601 need to be moved towards the interior of the stainless steel pipe 5. During the movement, the two abutting pieces 603 will abut against each other. When the two abutting pieces 603 abut against each other, the pressure will drive the first screw rod 618 to move towards the thread groove 620 inside the fixed cylinder 619. When the first screw rod 618 is connected to the thread groove 620, the first screw rod 618 will rotate, and at this time, the rotating circular plate 602 connected to the first screw rod 618 will also rotate, and finally the stainless steel pipe 5 will be fixed. This fixing method can ensure that when the fixed block 610 expands to fix the stainless steel pipe 5, the phenomenon that the fixed block 610 does not move into the interior of the stainless steel pipe 5 will not occur.

[0028] As Figures 8 to 9 shown, a plurality of anti-slip pieces 611 are provided at one end of the fixed block 610.

[0029] Specifically, by providing the anti-slip pieces 611, when the fixed block 610 is in contact with the inner wall of the stainless steel pipe 5, the friction between the fixed block 610 and the stainless steel pipe 5 can be increased, so that the fixing is more stable.

[0030] As Figures 8 to 9 shown, an adjusting spring 612 is provided at one end of the fixed block 610 away from the anti-slip pieces 611, and one end of the adjusting spring 612 is connected to the lifting block 615.

[0031] Specifically, by setting the adjusting spring 612, when the fixing block 610 fixes the stainless steel pipe 5, the adjusting spring 612 can adaptively adjust according to the different inner diameters of the stainless steel pipe 5, so as to ensure that the stainless steel pipe 5 will not be subjected to excessive abutting force.

[0032] As Figure 10 shown, one end of the lifting block 615 is provided with an auxiliary roller 617, and the auxiliary roller 617 slides on the surface of the fixed frame 601.

[0033] Specifically, by setting the auxiliary roller 617, when the lifting block 615 drives the fixing block 610 to move up and down, the auxiliary roller 617 can not only reduce the friction between the lifting block 615 and the fixing block 610, reduce the wear of the two, but also limit the moving track of the lifting block 615 to ensure the vertical movement of the lifting block 615.

[0034] As Figures 6 to 7 shown, a plurality of scrapers 613 are provided on the surface of the abutting piece 603.

[0035] Specifically, by setting the scraper 613 on the surface of the abutting piece 603, when the abutting piece 603 slides on the inner wall of the stainless steel pipe 5, the scraper 613 can scrape the inner wall of the stainless steel pipe 5, so as to scrape out the debris generated after cutting from the inside of the stainless steel pipe 5, realizing the cleaning of the inside of the stainless steel pipe 5.

[0036] As Figures 6 to 7 shown, a plurality of grooves are formed on the surface of the abutting piece 603, and the scraper 613 is arranged in the grooves, and connecting springs 614 are arranged at both ends of the scraper 613.

[0037] Specifically, when the scraper 613 scrapes the inner wall of the stainless steel pipe 5, the connecting spring 614 can make the scraper 613 have a certain adjustability. When scraping to a difficult-to-clean part, it can drive the scraper 613 to rotate, so as to avoid damage to both the stainless steel pipe 5 and the scraper 613.

[0038] As Figures 1 to 11As shown in the figure, a connecting rod 616 is provided at the lower end of the fixed frame 601. A sliding groove 606 is formed on the upper surface of the base frame 1, and the connecting rod 616 slides on the inner wall of the sliding groove 606. One end of the connecting rod 616 is connected to a second screw rod 624. A connecting belt 607 is provided inside the base frame 1, and the connecting belt 607 is sleeved on the surfaces of two second rotating plates 35. A connecting gear 605 is rotatably connected inside the base frame 1. One end of the connecting gear 605 is provided with an auxiliary shaft 623, and the auxiliary shaft 623 is located inside the connecting belt 607. A rotating disk 604 is provided at one end of the base frame 1 near the connecting gear 605, and the rotating disk 604 is threadedly connected to the second screw rod 624. A plurality of temporary storage grooves 625 are formed on the surface of the rotating disk 604. Tooth blocks 627 are provided inside the temporary storage grooves 625, and the tooth blocks 627 are meshed with the connecting gear 605. Coil springs 626 are provided at both ends of the tooth blocks 627.

[0039] Specifically, when the cutting edge of a stainless steel pipe 5 is completed and the cylinder 41 drives the fixed frame 601 to reset, the connecting rod 616 connected to the fixed frame 601 will drive the second screw rod 624 to move inside the rotating disk 604, so as to rotate the rotating disk 604. Moreover, the tooth blocks 627 outside the rotating disk 604 will be meshed with the connecting gear 605, so as to drive the second rotating plate 35 to rotate through the connecting belt 607. Finally, the transfer plate 32 automatically conveys the next stainless steel pipe 5 to be cut on the surface of the placement plate 31 to the position to be cut, realizing continuous operation. And when the second screw rod 624 drives the rotating disk 604 to rotate in the reverse direction, due to the lack of abutment on the surface of the rotating disk 604, when the tooth block 627 contacts the connecting gear 605, the tooth block 627 will move into the temporary storage groove 625, so as to ensure that the second rotating plate 35 will not rotate in the reverse direction at this time. And when the tooth block 627 does not contact the connecting gear 605, the coil spring 626 will release elastic force and drive the tooth block 627 to reset.

[0040] Embodiment 2: As Figure 13 shown, compared with Embodiment 1, another implementation manner of the present invention is: A blanking structure 2 is provided at one end of the placement plate 31. The blanking structure 2 includes a blanking frame 21. A first blocking strip 22 is slidably connected inside the blanking frame 21. One end of the first blocking strip 22 is provided with a separating piece 23. A second blocking strip 25 is slidably connected inside the blanking frame 21 near one end of the first blocking strip 22. A meshing gear 24 is rotatably connected to the outside of the blanking frame 21, and both the first blocking strip 22 and the second blocking strip 25 are meshed with the meshing gear 24.

[0041] Specifically, by setting the blanking structure 2, when trimming the stainless steel pipe 5, the stainless steel pipe 5 is placed inside the blanking frame 21, and then the meshing gear 24 is started to rotate. Since the meshing gear 24 meshes with both the first blocking strip 22 and the second blocking strip 25, when the second blocking strip 25 is opened, the first blocking strip 22 will block the subsequent stainless steel pipe 5, thereby ensuring that only one stainless steel pipe 5 is blanked each time, and the separating piece 23 at one end of the first blocking strip 22 can also separate the stainless steel pipe 5 more smoothly.

[0042] Working principle: When in use, first place the stainless steel pipe 5 inside the blanking frame 21, and then start the meshing gear 24 to rotate. Since the meshing gear 24 meshes with both the first blocking bar 22 and the second blocking bar 25, when the second blocking bar 25 opens, the first blocking bar 22 will block the subsequent stainless steel pipe 5, ensuring that only one stainless steel pipe 5 is unloaded each time. At this time, the stainless steel pipe 5 will be transferred to the placement groove 33 on the surface of the placement plate 31, and both ends of the stainless steel pipe 5 are located inside the transfer plate 32. Then start the second rotating plate 35 to rotate. Since the eccentric part of the second rotating plate 35 is connected to the eccentric part of the first rotating plate 34, the first rotating plate 34 will drive the transfer plate 32 to rotate at this time, thereby transferring the stainless steel pipe 5 inside the placement groove 33. When the stainless steel pipe 5 is transferred to the same vertical line as the fixed frame 601, start the cylinder 41. The cylinder 41 will drive the fixed frame 601 to move towards the inside of the stainless steel pipe 5 through the sliding block 43. During the movement, the two abutting pieces 603 will abut against each other. When the two abutting pieces 603 abut, the pressure will drive the first screw rod 618 to move towards the thread groove 620 inside the fixed cylinder 619. When the first screw rod 618 is connected to the thread groove 620, the first screw rod 618 will rotate. At this time, the rotating circular plate 602 connected to the first screw rod 618 will also rotate. While the rotating circular plate 602 is rotating, the two moving bars 609 will move along the inner wall of the moving groove 608. Since the moving bar 609 can only move up and down with the lifting block 615, the fixed block 610 will move vertically up and down at this time. Since the fixed block 610 has moved inside the stainless steel pipe 5 at this time, the two fixed blocks 610 will abut against the inner wall of the stainless steel pipe 5, thus completing the fixation of the stainless steel pipe 5. Then start the operation panel 46. The operation panel 46 will supply electrical energy to the cutting knife 45, causing the cutting knife 45 to rotate. And at this time, start the drive shaft 44 to rotate. Since the eccentric part of the drive shaft 44 is connected to the cutting knife 45, the cutting knife 45 will rotate around the drive shaft 44 while rotating itself, and then perform edge cutting on the stainless steel pipe 5 from the inside of the stainless steel pipe 5. Subsequently, when the edge cutting of one stainless steel pipe 5 is completed and the cylinder 41 drives the fixed frame 601 to reset, the connecting rod 616 connected to the fixed frame 601 will drive the second screw rod 624 to move inside the rotating disk 604, thereby rotating the rotating disk 604. And the tooth block 627 outside the rotating disk 604 will mesh with the connecting gear 605, thereby driving the second rotating plate 35 to rotate through the connecting belt 607, and finally enabling the transfer plate 32 to automatically convey the next stainless steel pipe 5 to be edge cut on the surface of the placement plate 31 to the position to be edge cut, realizing continuous operation.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present invention.
