Description

Technical Field

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

[0002] Stainless steel pipe is a hollow, long, round stainless steel product, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. Since the purchased stainless steel pipe is usually long, it needs to be cut according to demand.

[0003] A patent application with publication number CN110935932B discloses a stainless steel pipe cutting device, including a steel pipe storage and unloading device, a steel pipe feeding device and a steel pipe cutting device. The steel pipe storage and unloading device is used to store and unload steel pipes. On the one hand, the device solves the problem that friction between the pipe walls of adjacent steel pipes in the box prevents smooth unloading; on the other hand, it can make the steel pipes come out of the storage box in an orderly queue; on the other hand, when there is no need to unload the steel pipes, the storage box can lock the steel pipes in the box to prevent a large amount of steel pipes from overflowing from the box.

[0004] There are still some problems in the actual application of the above scheme. When cutting stainless steel pipes, although the above equipment can realize the orderly feeding of stainless steel pipes, the stainless steel pipes will be cut into several pieces of uniform length during the cutting work, so the workload of the cutting knife is huge. After cutting for a period of time, the cutting knife will become fatigued and even chipped, thereby affecting the cutting effect. Moreover, since the cutting work is carried out continuously, if the equipment is stopped when the cutting knife is fatigued and the cutting knife is replaced, the working cycle will be affected, and the positioning of the cutting knife will need to be performed again later, which is very cumbersome.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1: Figures 1 to 11 As shown, a stainless steel product cutting device according to an embodiment of the present invention includes a base frame 1, a conveying structure 2 is provided at the upper end of the base frame 1, the conveying structure 2 includes a conveying roller 22, a plurality of conveying rollers 22 are rotatably connected to the upper end of the base frame 1, a cutting structure 3 is provided at the lower end of the conveying roller 22, the cutting structure 3 includes a cutting knife 31, and an adjustment structure 4 is provided at one end of the cutting knife 31; the adjustment structure 4 includes: a lifting plate 411, the lifting plate 411 is slidably connected to the lower end of the base frame 1; a connecting shaft 417, the connecting shaft 417 is provided at one end of the lifting plate 411, and the connecting shaft 417 is clamped with the lifting plate 411 in the initial state; a driving rod 408, the driving rod 408 It is rotatably connected to the lower end of the base frame 1, and the driving rod 408 is engaged with the connecting shaft 417 when working; the first abutment piece 415, the first abutment piece 415 is provided on the surface of the connecting shaft 417 at one end close to the lifting plate 411; the second abutment piece 416, the second abutment piece 416 is provided on the surface of the connecting shaft 417 at one end close to the driving rod 408; the switching ring 414, the switching ring 414 is slidably connected to the surface of the connecting shaft 417, and the switching ring 414 is in contact with both the first abutment piece 415 and the second abutment piece 416 when working; the placing frame 422, the placing frame 422 is provided on the surface of the connecting shaft 417, and the placing frame 422 is movably connected to the cutting knife 31.

[0035] Specifically, a stainless steel product cutting device of the present invention is mainly used for cutting a stainless steel pipe 5. When in use, the stainless steel pipe 5 is first placed between the two conveying rollers 22, and then the conveying rollers 22 are started to convey the stainless steel pipe 5. When the portion of the stainless steel pipe 5 to be cut moves to the upper end of the cutting knife 31, the lifting plate 411 is started to move upward. Since the connecting shaft 417 is engaged with the lifting plate 411 at this time, the lifting plate 411 will drive the connecting shaft 417 to move upward together, and the cutting knife 31 connected to the connecting shaft 417 and the placing frame 422 will also be driven together. In the process of moving upward, the cutting knife 31 is started. 31 rotates, and when the cutting knife 31 contacts the stainless steel tube 5, since both ends of the stainless steel tube 5 are clamped by the conveying roller 22, the stainless steel tube 5 can be cut at this time. After a small section of the stainless steel tube 5 is cut, the lifting plate 411 is started to reset the cutting knife 31, and the conveying roller 22 near one end of the lifting plate 411 is started, so that the cut stainless steel tube 5 can be conveyed and transferred. Then, the conveying roller 22 near one end of the driving rod 408 is started again, so that the stainless steel tube 5 can continue to be conveyed to the position to be cut. However, after cutting for a period of time, the cutting knife 31 will become fatigued, or even chipped, thereby affecting the cutting effect. The adjusting structure 4 is set. After the cutting knife 31 is tired from working, the switching ring 414 is started. The switching ring 414 will slide on the surface of the connecting shaft 417 and contact the second abutment piece 416, thereby pushing the connecting shaft 417 to move through the second abutment piece 416, and then the connecting shaft 417 will be clamped with the driving rod 408. When the connecting shaft 417 is clamped with the driving rod 408, the connecting shaft 417 and the lifting plate 411 are not separated. As the switching ring 414 continues to move, the connecting shaft 417 and the lifting plate 411 will be separated. Then the driving rod 408 is started to rotate. During the rotation process, the driving rod 408 will drive the connecting shaft 417 and the placement frame The frame 422 rotates together, and the fatigued cutting knife 31 will also be driven to move. Since a new cutting knife 31 is installed at one end of the placement frame 422, the fatigued cutting knife 31 can be rotated away from the stainless steel pipe 5, and a new cutting knife 31 can be rotated to the position to be cut. Then, starting the switching ring 414 again can make the connecting shaft 417 and the lifting plate 411 continue to be engaged, so as to continue the cutting work. Moreover, since the cutting knife 31 is movably connected to the placement frame 422, the cutting knife 31 that has been working for a period of time can be replaced. Not only will it not affect the cutting work, but it will also be away from the cutting area, greatly reducing safety hazards.

[0036] like Figures 1 to 8As shown, the cutting structure 3 also includes a motor 32, which is provided at one end of the cutting knife 31, and the adjusting structure 4 also includes: a fixing plate 402, which is provided at the lower end of the base frame 1, and the driving rod 408 is provided inside the fixing plate 402; a clamping block 412, both the lifting plate 411 and the driving rod 408 are provided with a clamping block 412 at one end close to the connecting shaft 417; a card slot 419, which is opened at both ends of the connecting shaft 417; a sliding module 413, which is provided at one end of the lifting plate 411, and the sliding module 413 is connected to the switching ring 414; an operating frame 410, which is provided at one end of the lifting plate 411. 410 is arranged at the lower end of the base frame 1 near the motor 32; the sliding frame 405, the sliding frame 405 is arranged at one end of the operating frame 410, and the lifting plate 411 is slidably connected to the inner wall of the sliding frame 405; the second screw 421, the second screw 421 is rotatably connected to the end of the placement frame 422, and a sliding rod 420 is provided at one end of the second screw 421; the connecting piece 409, the connecting piece 409 is rotatably connected to the surface of the cutting knife 31, and the connecting piece 409 slides on the surface of the placement frame 422, the connecting piece 409 is threadedly connected to the second screw 421, and the connecting piece 409 is slidably connected to the sliding rod 420.

[0037] Specifically, when it is necessary to cut the stainless steel pipe 5, the lifting plate 411 is started, and the lifting plate 411 will drive the connecting shaft 417 to move upward through the engagement of the engaging block 412 with the engaging groove 419. Then, when it is necessary to replace the cutting blade 31, the sliding module 413 is started, and the sliding module 413 will control the movement of the switching ring 414, thereby realizing the engagement and separation of the driving rod 408 and the lifting plate 411 with the connecting shaft 417. Then, when the fatigued cutting blade 31 rotates away from the stainless steel pipe 5, the work is started. The second screw 421 on the side of the fatigue cutting knife 31 rotates. Since the connecting piece 409 is threadedly connected to the second screw 421 and the connecting piece 409 slides on the surface of the placement frame 422, the connecting piece 409 will move in the direction away from the cutting knife 31. When the connecting piece 409 is separated from the second screw 421, the connecting piece 409 will slide on the surface of the slide rod 420. Since the slide rod 420 is set to be "L" shaped, the connecting piece 409 can be folded, thereby realizing the replacement and installation of the cutting knife 31.

[0038] like Figures 1 to 6 As shown, a contact block 423 is provided at one end of the connecting shaft 417 close to the driving rod 408, and the contact block 423 contacts the driving rod 408 during operation. A telescopic rod 418 is provided at one end of the contact block 423, and the telescopic rod 418 is slidably connected to the inside of the connecting shaft 417. A buffer spring 424 is provided at one end of the telescopic rod 418, and one end of the buffer spring 424 contacts the connecting shaft 417.

[0039] Specifically, during the rotation of the driving rod 408, angular deviation is likely to occur, so that when the connecting shaft 417 is engaged with the driving rod 408, the engaging block 412 cannot be accurately engaged in the engaging groove 419. By providing a buffer spring 424, when the driving rod 408 needs to be connected to the connecting shaft 417, the driving rod 408 will first contact the abutting block 423. If the engaging block 412 is not accurately engaged with the engaging groove 419 at this time, the driving rod 408 is started to rotate, and due to the abutment of the driving rod 408, the abutting block 423 will move toward the direction of the connecting shaft 417. After the driving rod 408 rotates a certain angle, the engaging block 412 will fit into the position of the engaging groove 419. At this time, the buffer spring 424 releases its elastic force, which can push the abutting block 423 toward the direction of the driving rod 408, and finally the connecting shaft 417 is engaged with the driving rod 408.

[0040] like Figures 1 to 3 As shown, a rotating block 403 is provided at the upper end of the base frame 1 , and a connecting rod 404 is rotatably connected inside the rotating block 403 , and an abutting ring 401 is provided at one end of the connecting rod 404 .

[0041] Specifically, by setting the abutment ring 401, when the stainless steel pipe 5 needs to be cut, the rotating block 403 is started, and the rotating block 403 will drive the abutment ring 401 to rotate through the connecting rod 404, thereby abutting and limiting the upper end of the stainless steel pipe 5 to facilitate the cutting of the stainless steel pipe 5, and the position of the rotating block 403 on the upper end of the base frame 1 can also be adjusted to cope with different cutting parts of the stainless steel pipe 5.

[0042] like Figures 1 to 3 As shown, a blowing module 407 is provided on one side of the abutting ring 401 , a nozzle 406 is provided at the lower end of the abutting ring 401 , and the blowing module 407 is communicated with the nozzle 406 .

[0043] Specifically, when the cutting knife 31 cuts the stainless steel tube 5, the abutment ring 401 will limit the upper end of the stainless steel tube 5. At this time, the blowing module 407 is started, and the blowing module 407 will blow air through the nozzle 406. Since the nozzle 406 is set at an angle and the end points to the cutting part, the blown gas will blow away the debris generated by the cutting of the stainless steel tube 5, thereby preventing these debris from falling on the surface of the fixing plate 402 and the operating frame 410.

[0044] Example 2: Figures 1 to 11 As shown, in comparison with Example 1, another embodiment of the present invention is that: a plurality of conveying rollers 22 are slidably connected to the upper end of the base frame 1.

[0045] Specifically, when the conveying rollers 22 clamp and convey the stainless steel tube 5 , the distance between the upper and lower rows of conveying rollers 22 can be adjusted to cope with stainless steel tubes 5 with different inner diameters.

[0046] like Figures 10 and 11 As shown, a conveying frame 21 is provided at the upper end of the base frame 1 , and the conveying frame 21 is connected to a conveying roller 22 , and an adjusting spring 24 is provided between the conveying frame 21 and the base frame 1 .

[0047] Specifically, when the stainless steel tube 5 contacts the conveying roller 22, the conveying roller 22 at the lower end of the stainless steel tube 5 will be fixed, and the conveying roller 22 at the upper end of the stainless steel tube 5 will be adjusted up and down through the conveying frame 21 to cope with stainless steel tubes 5 with different inner diameters.

[0048] like Figure 10 As shown, the interior of the regulating spring 24 is sheathed with the limiting rod 23 , and the conveying frame 21 slides on the surface of the limiting rod 23 .

[0049] Specifically, by setting a limit rod 23, when the conveying frame 21 drives the conveying roller 22 to adjust its position, the limit rod 23 will limit the moving direction of the conveying frame 21, so that the conveying frame 21 can only move vertically to facilitate the conveyance of the stainless steel pipe 5.

[0050] like Figures 1 to 11 As shown, one end of the inner wall of the base frame 1 close to the conveying frame 21 is rotatably connected to two guide rods 27.

[0051] Specifically, by setting the guide rods 27, when the conveying roller 22 conveys the stainless steel tube 5, the angles of the two guide rods 27 can be adjusted according to the inner diameter of the stainless steel tube 5, so that the stainless steel tube 5 is always located at the center position of the conveying roller 22 for subsequent cutting work.

[0052] like Figures 10 and 11 As shown, an adjusting ring 26 is rotatably connected to the inner wall of the base frame 1 , and the adjusting ring 26 is connected to the guide rod 27 . A first screw 25 is provided at the lower end of the conveying frame 21 , and the first screw 25 is threadedly connected to the adjusting ring 26 .

[0053] Specifically, by setting the first screw 25, and the first screw 25 is located inside the adjustment ring 26 in the initial state, during the adjustment of the conveying roller 22, the first screw 25 connected to the conveying frame 21 will also move, and during the movement, the first screw 25 will engage with the adjustment ring 26, thereby causing the adjustment ring 26 to rotate, and finally the guide rod 27 connected to the adjustment ring 26 will automatically adjust according to the movement of the first screw 25.

[0054] Working principle: When in use, first place the stainless steel pipe 5 between the two conveying rollers 22, then start the conveying rollers 22 to convey the stainless steel pipe 5, and when the part to be cut of the stainless steel pipe 5 moves to the upper end of the cutting knife 31, start the lifting plate 411 to move upward. Since the connecting shaft 417 is engaged with the lifting plate 411 at this time, the lifting plate 411 will drive the connecting shaft 417 to move upward together, and the cutting knife 31 connected to the connecting shaft 417 and the placing frame 422 will also be driven together. In the process of moving upward, start the cutting knife 31 to rotate. When the cutting knife 31 contacts the stainless steel pipe 5, since both ends of the stainless steel pipe 5 are clamped by the conveying rollers 22, At this time, the stainless steel pipe 5 can be cut. After a small section of the stainless steel pipe 5 is cut, the lifting plate 411 is started to reset the cutting knife 31, and the conveying roller 22 near one end of the lifting plate 411 is started to convey and transfer the cut stainless steel pipe 5. Then, the conveying roller 22 near one end of the driving rod 408 is started again to continue to convey the stainless steel pipe 5 to the position to be cut. When the cutting knife 31 needs to be replaced, the sliding module 413 is started. The sliding module 413 will control the movement of the switching ring 414, so that the switching ring 414 will slide on the surface of the connecting shaft 417 and contact the second abutment piece 416, thereby pushing the connecting shaft 417 through the second abutment piece 416. The connecting shaft 417 is moved, and then the connecting shaft 417 will be engaged with the driving rod 408, and when the connecting shaft 417 is engaged with the driving rod 408, the connecting shaft 417 and the lifting plate 411 are not separated. As the switching ring 414 continues to move, the connecting shaft 417 and the lifting plate 411 will be separated, and then the driving rod 408 is started to rotate. During the rotation process, the driving rod 408 will drive the connecting shaft 417 and the placement frame 422 to rotate together, and at this time the tired cutting knife 31 will also be driven to transfer. Since a new cutting knife 31 is installed at one end of the placement frame 422 at this time, the tired cutting knife 31 can be rotated away from the stainless steel pipe 5, and a new cutting knife 31 can be rotated. The cutting blade 31 is moved to the position to be cut, and then the switching ring 414 is started again to make the connecting shaft 417 continue to be engaged with the lifting plate 411, so as to continue the cutting work. At this time, the second screw 421 on the side of the working fatigue cutting blade 31 is started to rotate. Since the connecting piece 409 is threadedly connected to the second screw 421, and the connecting piece 409 slides on the surface of the placement frame 422, the connecting piece 409 will move in the direction away from the cutting blade 31 at this time, and when the connecting piece 409 is separated from the second screw 421, the connecting piece 409 will slide on the surface of the slide bar 420. Since the slide bar 420 is set to an "L" shape, the connecting piece 409 can be folded, thereby realizing the replacement and installation of the cutting blade 31.
