Description

Technical Field

[0001] This invention belongs to the field of stainless steel profile trimming technology, specifically a stainless steel profile trimming device. Background Technology

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

[0003] A patent application with publication number CN119159386A discloses a trimming device for processing stainless steel products. The device includes a base frame, on which a first conveyor belt and a second conveyor belt are respectively arranged on the left and right sides. A flying shear device and a rolling shear device are respectively located on the left and right sides of the second conveyor belt on the base frame. The first conveyor belt includes four conveyor belts arranged in a square array. The device reduces the downtime during the trimming process by the continuous operation of the rolling shear device and the flying shear device, thereby improving the continuity of the production process and the overall efficiency. Furthermore, by equipping the device with a grinding component, it effectively removes burrs from the edges of the trimmed stainless steel plates, improving product quality and reducing safety risks in subsequent processing.

[0004] The above-mentioned solution still has some problems in practical application. When using the above-mentioned device to trim the stainless steel pipe, both ends of the stainless steel pipe need to be treated. The existing device fixes the stainless steel pipe by clamping the ends of the stainless steel pipe. This method will separate the trimming work at both ends of the stainless steel pipe. While clamping one end, the trimming work at the other end is carried out. Then, the device is switched to complete the trimming work at both ends, which reduces the trimming efficiency. Moreover, when the trimming of one end of the stainless steel pipe is completed and the other end is switched to be fixed, the position of the stainless steel pipe and the cutting blade needs to be repositioned. If the positioning is not accurate, the processing accuracy will be reduced and the trimming quality will be affected.

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

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The stainless steel profile trimming device of the present invention, by setting an adjustment structure, when trimming stainless steel pipes, firstly, several stainless steel pipes are placed in the placement groove on the surface of the placement plate. At this time, the cylinder is activated, and two cylinders will drive the fixed frame to move towards the inside of the stainless steel pipe. When the two abutting plates contact and abut, the pressure will drive the first screw to move towards the inside of the fixed cylinder, and then connect with the threaded groove inside the fixed cylinder, thereby causing the first screw to rotate. The rotating circular plate connected to the first screw will also rotate. At the same time, the two moving strips will move along the inner wall of the moving groove, thereby causing the fixed block connected to the moving strips to move vertically upwards and downwards. Since the fixed block has moved into the inside of the stainless steel pipe, the fixing of the stainless steel pipe is completed.

[0035] 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.

[0036] Example 1: As Figures 1 to 13As shown, an embodiment of the present invention provides a stainless steel profile trimming device, comprising a base frame 1, a conveying structure 3 at the upper end of the base frame 1, the conveying structure 3 including a placement plate 31, the placement plate 31 being disposed at the upper end of the base frame 1, and a placement groove 33 being formed on the surface of the placement plate 31, both ends of the placement plate 31 being slidably connected to a transfer plate 32, the lower end of the transfer plate 32 being provided with two first rotating plates 34, and two second rotating plates 35 being rotatably connected inside the base frame 1, with the eccentric portion of the second rotating plate 35 connected to the eccentric portion of the first rotating plate 34; trimming structures 4 are provided on both sides of the placement plate 31, and an adjustment structure 6 is provided at one end of the trimming structure 4 near the placement plate 31; the adjustment structure 6 includes: a fixing frame. 601, a fixed frame 601 is located on the upper end of the base frame 1 near the placement plate 31; two fixed blocks 610 are slidably connected to one end of the fixed frame 601; the cutting structure 4 includes: a cylinder 41, two cylinders 41 are located on the upper end of the base frame 1; a sliding block 43 is located at the end of the cylinder 41 and the cylinder 41 is connected to the sliding block 43; an operation disc 46 is rotatably connected to one end of the fixed frame 601; a cutting blade 45 is rotatably connected to the surface of the operation disc 46 and the operation disc 46 is used to control the cutting blade 45; a drive shaft 44 is located on the surface of the operation disc 46 and the drive shaft 44 is connected to the eccentric part of the cutting blade 45.

[0037] Specifically, this solution provides a stainless steel profile trimming device, mainly used for trimming stainless steel tubes 5. In use, the stainless steel tube 5 is first transferred to the placement groove 33 on the surface of the placement plate 31. At this time, both ends of the stainless steel tube 5 are located inside the transfer plate 32. Then, the second rotating plate 35 is activated. 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, thereby transferring the stainless steel tube 5 inside the placement groove 33. When the stainless steel tube 5 is transferred to the same vertical line as the fixed frame 601, the cylinder 41 is activated. The cylinder 41 will drive the fixed frame 601 to move towards the inside of the stainless steel tube 5 via the sliding block 43. When the end of the fixed frame 601 moves into the inside of the stainless steel tube 5, the fixing block 610 is activated. The two fixing blocks 610 will then respectively... The device moves upwards and downwards, eventually contacting the inner wall of the stainless steel tube 5 to secure it. Then, the operating panel 46 is activated, supplying electrical energy to the cutting blade 45, causing it to rotate. Simultaneously, the drive shaft 44 rotates. Since the drive shaft 44 is connected to the eccentric part of the cutting blade 45, the cutting blade 45 rotates around the drive shaft 44 while rotating on its own axis, thus trimming the stainless steel tube 5 from the inside. The transfer plate 32 of this device can continuously transfer the stainless steel tube 5, allowing for continuous trimming. Furthermore, the adjustment structure 6 can simultaneously trim both ends of the stainless steel tube 5 while it is secured. Because the trimming is performed inside the stainless steel tube 5, it also protects the outer coating of the stainless steel tube 5 from wear.

[0038] like Figures 1 to 9 As 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 formed 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 and is connected to the fixed block 610; and a moving strip 609, which is located at one end of the lifting block 615 and slides on the inner wall of the moving groove 608. The trimming structure 4 further includes: a slide rail 42, which is located at the upper end of the base frame 1 and a sliding block 43 slides on the surface of the slide rail 42.

[0039] Specifically, when the end of the fixed frame 601 moves into the interior of the stainless steel tube 5, the rotating plate 602 is started to rotate. While the rotating plate 602 is rotating, the two moving bars 609 will move along the inner wall of the moving groove 608. Since the moving bars 609 can only move up and down with the lifting block 615, the fixed block 610 will also move vertically to the upper and lower ends. Since the fixed block 610 has moved into the interior of the stainless steel tube 5, the fixing of the stainless steel tube 5 is completed at this time.

[0040] like Figures 1 to 10 As shown, the rotating circular plate 602 has a first screw 618 inside, and the first screw 618 passes through the fixed frame 601 and the operating plate 46. The end of the first screw 618 near the placement plate 31 has an abutment piece 603, and the other end of the first screw 618 is rotatably connected to a connecting post 621. The sliding block 43 has a fixed cylinder 619 near the fixed frame 601, and the first screw 618 and the connecting post 621 slide inside the fixed cylinder 619. The fixed cylinder 619 has a threaded groove 620 inside, and the first screw 618 is threadedly connected to the threaded groove 620. One end of the connecting post 621 has a return spring 622, and the other end of the return spring 622 is connected to the inner wall of the fixed cylinder 619.

[0041] Specifically, when trimming the stainless steel tube 5, the two fixing frames 601 need to be moved towards the inside of the stainless steel tube 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 618 to move towards the threaded groove 620 inside the fixing cylinder 619. When the first screw 618 is connected to the threaded groove 620, the first screw 618 will rotate. At this time, the rotating circular plate 602 connected to the first screw 618 will also rotate and finally fix the stainless steel tube 5. This fixing method can ensure that when the fixing block 610 is unfolded to fix the stainless steel tube 5, the fixing block 610 will not fail to move into the stainless steel tube 5.

[0042] like Figures 8 to 9 As shown, one end of the fixing block 610 is provided with several anti-slip pieces 611.

[0043] Specifically, by setting anti-slip plate 611, the friction between the fixing block 610 and the stainless steel pipe 5 can be increased when the fixing block 610 comes into contact with the inner wall of the stainless steel pipe 5, thereby making the fixing more stable.

[0044] like Figures 8 to 9 As shown, the fixed block 610 is provided with an adjusting spring 612 at the end away from the anti-slip plate 611, and one end of the adjusting spring 612 is connected to the lifting block 615.

[0045] Specifically, by setting an adjusting spring 612, when the fixing block 610 fixes the stainless steel tube 5, the adjusting spring 612 can adaptively adjust to different inner diameters of the stainless steel tube 5, thereby ensuring that the stainless steel tube 5 is not subjected to excessive resistance force.

[0046] like Figure 10 As 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.

[0047] Specifically, by setting an auxiliary roller 617, when the lifting block 615 drives the fixed block 610 to move up and down, the auxiliary roller 617 can not only reduce the friction between the lifting block 615 and the fixed block 610 and reduce the wear of both, but also limit the movement trajectory of the lifting block 615 to ensure the vertical movement of the lifting block 615.

[0048] like Figures 6 to 7 As shown, the surface of the abutment piece 603 is provided with a plurality of scrapers 613.

[0049] Specifically, by setting a scraper 613 on the surface of the abutment piece 603, when the abutment piece 603 slides on the inner wall of the stainless steel tube 5, the scraper 613 can scrape the inner wall of the stainless steel tube 5, thereby scraping out the debris generated after cutting from the inside of the stainless steel tube 5, and achieving cleaning of the inside of the stainless steel tube 5.

[0050] like Figures 6 to 7 As shown, the surface of the abutment piece 603 has several grooves, and the scraper 613 is located in the grooves. Both ends of the scraper 613 are provided with connecting springs 614.

[0051] Specifically, when the scraper 613 scrapes the inner wall of the stainless steel tube 5, the connecting spring 614 allows the scraper 613 to have a certain degree of adjustability. When scraping areas that are difficult to clean, the scraper 613 can be rotated to avoid damage to both the stainless steel tube 5 and the scraper 613.

[0052] like Figures 1 to 11As shown, the lower end of the fixed frame 601 is provided with a connecting rod 616, the upper surface of the base frame 1 is provided with a sliding groove 606, 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 624. The inside of the base frame 1 is provided with a connecting belt 607, and the connecting belt 607 is sleeved on the surface of two second rotating plates 35. The inside of the base frame 1 is rotatably connected with a connecting gear 605. 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. The inside of the base frame 1 near the connecting gear 605 is provided with a rotating disk 604, and the rotating disk 604 is threadedly connected to the second screw 624. The surface of the rotating disk 604 is provided with several temporary storage slots 625. The inside of the temporary storage slots 625 is provided with tooth blocks 627, and the tooth blocks 627 mesh with the connecting gear 605. Both ends of the tooth blocks 627 are provided with coil springs 626.

[0053] Specifically, after the stainless steel pipe 5 is trimmed 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 624 to move inside the rotating disk 604, thereby causing the rotating disk 604 to rotate. The toothed block 627 on the outside of the rotating disk 604 will mesh with the connecting gear 605, thereby driving the second rotating plate 35 to rotate via the connecting belt 607. Ultimately, the transfer plate 32 will automatically place the next stainless steel pipe to be trimmed on the surface of the placement plate 31. The steel pipe 5 is conveyed to the position to be cut to achieve continuous operation. When the second screw 624 drives the rotating disk 604 to rotate in the opposite direction, since there is no contact between the rotating disk 604 and the toothed block 627 and the connecting gear 605, the toothed block 627 will move into the interior of the temporary storage groove 625. This ensures that the second rotating plate 35 will not rotate in the opposite direction at this time. When the toothed block 627 is not in contact with the connecting gear 605, the coil spring 626 will release its elastic force and drive the toothed block 627 to reset.

[0054] Example 2: Figure 13 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: one end of the placement plate 31 is provided with a feeding structure 2, the feeding structure 2 includes a feeding frame 21, a first blocking strip 22 is slidably connected inside the feeding frame 21, a separation piece 23 is provided at one end of the first blocking strip 22, a second blocking strip 25 is slidably connected inside the feeding frame 21 near the end of the first blocking strip 22, and a meshing gear 24 is rotatably connected to the outside of the feeding frame 21, and both the first blocking strip 22 and the second blocking strip 25 mesh with the meshing gear 24.

[0055] Specifically, by setting up the feeding structure 2, when the stainless steel tube 5 is being trimmed, the stainless steel tube 5 is placed inside the feeding frame 21, and then the meshing gear 24 is started to rotate. Since the meshing gear 24 is engaged with both the first blocking bar 22 and the second blocking bar 25, when the second blocking bar 25 is opened, the first blocking bar 22 will block the stainless steel tube 5 behind it, thus ensuring that only one stainless steel tube 5 is fed at a time. In addition, the separating plate 23 located at one end of the first blocking bar 22 can also separate the stainless steel tube 5 more smoothly.

[0056] Working principle: In use, the stainless steel tube 5 is first placed inside the feeding frame 21. Then, the meshing gear 24 is started to rotate. Since the meshing gear 24 is engaged 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 stainless steel tube 5 behind it, thus ensuring that only one stainless steel tube 5 is fed at a time. At this time, the stainless steel tube 5 will be transferred to the placement groove 33 on the surface of the placement plate 31, and both ends of the stainless steel tube 5 are located inside the transfer plate 32. Then, the second rotating plate 35 is started 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... This will cause the transfer plate 32 to rotate, thereby transferring the stainless steel tube 5 inside the placement groove 33. When the stainless steel tube 5 is transferred to a position on the same vertical line as the fixed frame 601, the cylinder 41 is activated. The cylinder 41 will drive the fixed frame 601 to move towards the inside of the stainless steel tube 5 through the sliding block 43. During the movement, the two abutting plates 603 will abut against each other. When the two abutting plates 603 abut against each other, the pressure will drive the first screw 618 to move towards the threaded groove 620 inside the fixed cylinder 619. When the first screw 618 is connected to the threaded groove 620, the first screw 618 will rotate. At this time, the rotating circular plate 602 connected to the first screw 618 will also rotate. As the circular plate 602 rotates, the two moving bars 609 will move along the inner wall of the moving groove 608. Since the moving bars 609 can only move up and down with the lifting block 615, the fixing block 610 will also move vertically towards the upper and lower ends. Since the fixing block 610 has now moved into the interior of the stainless steel tube 5, the two fixing blocks 610 will abut against the inner wall of the stainless steel tube 5, thereby completing the fixing of the stainless steel tube 5. Then, the operation panel 46 is activated, which will supply electrical energy to the cutting blade 45, causing the cutting blade 45 to rotate. At the same time, the drive shaft 44 is activated to rotate. Since the drive shaft 44 is connected to the eccentric part of the cutting blade 45, the cutting blade 45 will rotate. Simultaneously, the cylinder 41 will rotate around the drive shaft 44, thereby cutting the stainless steel tube 5 from the inside. After the cutting of one stainless steel tube 5 is completed, when 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 624 to move inside the rotating disk 604, thereby causing the rotating disk 604 to rotate. The toothed block 627 on the outside of 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. Finally, the transfer plate 32 will automatically transport the next stainless steel tube 5 to be cut to the position on the surface of the placement plate 31, realizing continuous operation.
