Description

Technical Field

[0001] The present invention relates to the technical field of seamless steel pipe cutting, and specifically to a steel pipe cutting device for oxygen pipelines. Background Technique

[0002] In recent years, with the rapid development of the industrial field, the demand for stainless steel seamless steel pipes for oxygen pipelines has been continuously increasing. As a kind of pipe material with advantages such as high corrosion resistance, high strength, and long service life, stainless steel seamless steel pipes have been widely used in fields such as petroleum, chemical industry, and electric power.

[0003] The Chinese invention patent with the publication number of CN116713526A discloses a seamless steel pipe cutting device with a quick fixing structure, including a cutting machine frame. On one side of the upper surface of the cutting machine frame, a sliding mechanism is arranged, and a first clamping mechanism is arranged on the sliding mechanism. In the middle of the upper surface of the cutting machine frame, a cutting mechanism is installed. For this seamless steel pipe cutting device with a quick fixing structure, through the use of the auxiliary clamping mechanism, when the seamless steel pipe is being cut, the seamless steel pipe will be subjected to a large force. At this time, the auxiliary clamping mechanisms on both sides of the cutting mechanism can effectively fix the seamless steel pipe to avoid the seamless steel pipe from shaking during cutting. When in use, when the seamless steel pipe moves to the cutting position, at this time, control the fourth motor to drive the second bidirectional screw to rotate, and then use the second bidirectional screw to drive two second arc-shaped fixing clips to move inward, and clamp the position of the seamless steel pipe close to the cutting point through the second arc-shaped fixing clips.

[0004] However, the above patent still has the following deficiencies in the actual use process: 1. This patent can avoid the seamless steel pipe from shaking during cutting, but when loading the material, it is necessary to place the seamless steel pipe into the inner cavity of the arc-shaped support plate at the top of the first electric push rod, and then start the first electric push rod to assist in lifting the seamless steel pipe. When unloading the material, it is also necessary to place one end of the cut seamless steel pipe into the inner cavity of the arc-shaped support plate above the second electric push rod. This way of loading and unloading is very cumbersome, reducing the cutting efficiency of the steel pipe; 2. The cut waste cannot be automatically discharged for collection, resulting in workers still needing to separately collect the cut waste manually, which is time-consuming and laborious. Summary of the Invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 - 9 The present invention describes the above technical solution in detail through the following embodiments:

[0032] A steel pipe cutting device for oxygen pipelines comprises a feeding machine box 1 and a feeding bracket 2, wherein the feeding machine box 1 is arranged in an inclined manner, a rotating chamber 11 with a circular cross section is arranged in the feeding machine box 1, a rotating shaft 12 is arranged in the rotating chamber 11, a feeding roller 121 matching the rotating chamber 11 is arranged on the rotating shaft 12, a plurality of material placing grooves 1211 distributed at equal angles along the circumference of the feeding roller 121 are arranged on the outer wall of the feeding roller 121, and a material placing groove 1211 is arranged on the back of the feeding machine box 1 for driving the rotating shaft 12 to rotate intermittently. The top of the feeding box 1 is provided with a feeding port 14 connected to the rotating chamber 11 and a feeding hopper 3 connected to the feeding port 14, the bottom of the feeding box 1 is provided with a discharging port 15 connected to the rotating chamber 11, a discharging hopper 4 connected to the discharging port 15 and four supporting feet 16, the front of the feeding box 1 is provided with a steel pipe discharging frame 17 and an auxiliary knocking mechanism 5, and the steel pipe discharging frame A material passing trough 171 matching the material placing trough 1211 is provided in 17, a cutting mechanism 6 is provided on the top of the steel pipe discharging frame 17, a clamping mechanism 7 for clamping and positioning the steel pipe is provided on one side wall of the steel pipe discharging frame 17, the clamping mechanism 7 is transmission connected with the cutting mechanism 6, the auxiliary knocking mechanism 5 is transmission connected with the other end of the rotating shaft 12, the upper half of the unloading bracket 2 is tilted and rotated with a swivel 21, one end of the swivel 21 is provided with a semi-ring bearing plate 22 connected thereto, the bottom of the semi-ring bearing plate 22 is provided with a limiting mechanism 8 for limiting the steel pipe in the semi-ring bearing plate 22, the top of the unloading bracket 2 is provided with a rotating mechanism 9 for driving the swivel 21 to rotate, the unloading bracket 2 is located at the front side of the loading machine box 1, and a cutting gap is formed between the semi-ring bearing plate 22 and the steel pipe discharging frame 17, a residual material guiding discharging frame 10 is provided directly below the semi-ring bearing plate 22, and a steel pipe guiding discharging frame 20 is provided directly below the other end of the swivel 21.

[0033] The present invention adopts a feeding machine case 1 arranged obliquely, enabling seamless steel pipes in the material placing groove 1211 to move downward by their own gravity. After the material placing groove 1211 is butted against the steel pipe discharging frame 17, the seamless steel pipes can be automatically discharged onto the semi-circular bearing plate 22. The cutting mechanism 6 can cut the seamless steel pipes. While cutting, the cutting mechanism 6 can also drive the clamping mechanism 7 to clamp the seamless steel pipes to prevent the seamless steel pipes from shaking. The limiting mechanism 8 can release the limitation on the cut steel pipes, enabling the cut steel pipes to be discharged from the rotating ring 21. Then, the steel pipes are led out through the steel pipe guiding discharging frame 20. After the cutting mechanism 6 stops working, the remaining materials can be limited by the limiting mechanism 8, and then the remaining materials can be discharged into the remaining material guiding discharging frame 10 through the rotating mechanism 9. The remaining materials can be automatically discharged for collection, improving the efficiency of steel pipe cutting.

[0034] It should be noted that collection boxes can be arranged below the feeding hopper 4, below the steel pipe guiding discharging frame 20, and below the remaining material guiding discharging frame 10 respectively to facilitate the centralized collection of debris, cut steel pipes, and remaining materials.

[0035] During use, first place multiple seamless steel pipes into the feeding hopper 3. The feeding hopper 3 includes a discharging pipeline 31 and two movable side plates 32. At the top of the discharging pipeline 31, there are two symmetrically arranged side plates 33 integrally connected thereto. At both ends of the inner wall of the side plate 33, third sliding grooves 331 are opened. A number of equally spaced third screw holes 332 are opened on the third sliding grooves 331. At both ends of the movable side plate 32, there are second supporting ears 321 slidably matched with the third sliding grooves 331. At the top of the second supporting ear 321, a fourth screw hole 3211 is opened. A second screw 3212 is screwed into the fourth screw hole 3211, and the second screw 3212 is screwed and matched with the third screw hole 332. The discharging pipeline 31 is fixedly connected to the top of the feeding machine case 1 and is communicated with the feeding port 14.

[0036] Loosen the second screw 3212 so that the second screw 3212 can disengage from the third screw hole 332 and the fourth screw hole 3211. The second supporting ear 321 loses the locking and fixing force, that is, the movable side plate 32 loses the locking and fixing force, and the movable side plate 32 can be adjusted. The distance between the two movable side plates 32 can be adjusted. Then tighten the second screw 3212, and the movable side plate 32 can be fixed. In this way, the feeding hopper 3 can place seamless steel pipes of different lengths.

[0037] The seamless steel pipes can be arranged in sequence within the discharge pipeline 31. The driving motor 13 drives the rotating shaft 12 and the loading roller 121 to rotate intermittently. When a material placement groove 1211 is docked with the discharge pipeline 31, the seamless steel pipe at the lowest end of the discharge pipeline 31 can enter the material placement groove 1211 by its own gravity. Then, the seamless steel pipe moves synchronously with the loading roller 121. While the rotating shaft 12 is rotating, it also drives the auxiliary knocking mechanism 5 to work. The auxiliary knocking mechanism 5 includes a linkage turntable 51 and a lifting guide seat 52. A number of abutting rods 53 are arranged on the linkage turntable 51 at equal angular intervals along its circumference. One end of the abutting rod 53 is provided with an arc surface 531. A lifting guide rod 54 is slidably arranged on the lifting guide seat 52. The top of the lifting guide rod 54 is provided with a first wedge surface 541 that cooperates with the arc surface 531. The bottom end of the lifting guide rod 54 is provided with a support plate 55 perpendicular to it. Two vertical first springs 551 are arranged on the support plate 55. One end of the first spring 551 is fixedly connected to the bottom of the lifting guide seat 52. One end of the support plate 55 is provided with a mounting plate 56. A number of knocking rods 561 are arranged on the mounting plate 56. The linkage turntable 51 is fixedly connected to the other end of the rotating shaft 12. The lifting guide seat 52 is fixedly connected to the front outer wall of the loading machine case 1. The mounting plate 56 is located directly below the bottom of the loading machine case 1.

[0038] After the rotating shaft 12 rotates, it not only drives the loading roller 121 to rotate but also drives the linkage turntable 51 to rotate. All the abutting rods 53 on the linkage turntable 51 also rotate synchronously. The arc surface 531 on the abutting rod 53 can gradually abut against the first wedge surface 541. Then, the abutting rod 53 transfers the rotational force to the lifting guide rod 54. The lifting guide rod 54 moves downward on the lifting guide seat 52. The lifting guide rod 54 drives the support plate 55 and the mounting plate 56 to move downward synchronously. The two first springs 551 are stretched. The knocking rods 561 also move downward with the mounting plate 56 and move away from the bottom of the loading machine case 1. After the abutting rod 53 disengages from the lifting guide rod 54, the elastic force of the two first springs 551 can drive the support plate 55 to move upward. The support plate 55 drives the mounting plate 56, the lifting guide rod 54, and all the knocking rods 561 to move upward synchronously. The knocking rods 561 knock on the bottom of the loading machine case 1, so that the impurities carried on the outer wall of the seamless steel pipe in the material placement groove 1211 can be separated from the seamless steel pipe. Then, the impurities can be discharged into the lower material hopper 4 through the discharge port 15. Of course, this knocking force can also make the seamless steel pipe slide easily by its own gravity.

[0039] Afterwards, the rear material placing groove 1211 gradually docks with the steel pipe discharging frame 17. The seamless steel pipes in the material placing groove 1211 move by their own weight. Then, the seamless steel pipes slide into the material passing groove 171. Immediately afterwards, the seamless steel pipes can slide onto the semi-circular bearing plate 22. The position of the seamless steel pipes entering the semi-circular bearing plate 22 is limited by the limiting mechanism 8. The limiting mechanism 8 includes a pushing electric push rod 81, a mounting rod 82, and a limiting disk 83 matching the rotating ring 21. In the middle of the top of the mounting rod 82, there is a guiding slider 821. On both sides of the guiding slider 821, there are vertically arranged lifting cylinders 822. On both outer walls of the limiting disk 83, there are first ear plates 831. At the bottom of the semi-circular bearing plate 22, there is a second chute 221. The pushing electric push rod 81 is fixedly connected to the bottom of the semi-circular bearing plate 22. The guiding slider 821 is slidably arranged in the second chute 221. The output ends of the two lifting cylinders 822 are respectively fixedly connected to the bottoms of the two second ear plates 321.

[0040] The limiting disk 83 can block the seamless steel pipes. By driving the mounting rod 82 to move through the pushing electric push rod 81, the mounting rod 82 can drive the lifting cylinders 822 and the limiting disk 83 to move synchronously, so as to adjust the position of the limiting disk 83 on the semi-circular bearing plate 22, that is, change the cutting length of the seamless steel pipes. Subsequently, the cutting mechanism 6 and the clamping mechanism 7 work.

[0041] The cutting mechanism 6 includes a first bracket 61, a lifting electric push rod 62, a cutting motor 63, and a cutting knife 64. An installation ring body 65 is installed on the output end of the lifting electric push rod 62. The first bracket 61 is fixedly connected to the top of the steel pipe discharging frame 17. The lifting electric push rod 62 is vertically and fixedly connected to the top of the first bracket 61. The cutting motor 63 is arranged in the installation ring body 65. The cutting knife 64 is fixedly connected to the output end of the cutting motor 63. The cutting knife 64 is located in the cutting gap.

[0042] The clamping mechanism 7 includes a clamping plate 71. On the back of the clamping plate 71, there are two guiding rods 72. One end of each guiding rod 72 is provided with a limiting plate 73. A second spring 74 is sleeved on the guiding rods 72. Between the two guiding rods 72, there is a linkage block 75. One end of the linkage block 75 is provided with a second wedge surface 751. On the outer wall of the installation ring body 65, there is a synchronous rod 651. A pressing rod 652 is detachably connected to the synchronous rod 651. At the bottom of the pressing rod 652, there is a third wedge surface 6521 that cooperates with the second wedge surface 751. Embedded grooves are formed on the inner walls of the rotating cavity 11 and the steel pipe discharging frame 17. Guide holes that are in guiding cooperation with the guiding rods 72 are formed on the outer walls of the feeding machine case 1 and the steel pipe discharging frame 17. A sliding hole that is in sliding cooperation with the linkage block 75 is also formed on the outer wall of the steel pipe discharging frame 17. The clamping plate 71 is slidably arranged in the embedded groove. The pressing rod 652 is located directly above the linkage block 75.

[0043] The lifting electric push rod 62 is driven to lower the mounting ring body 65. The mounting ring body 65 drives the cutting motor 63 and the cutting knife 64 to move downward. When the mounting ring body 65 moves downward, it also drives the synchronizing rod 651 to move downward. The synchronizing rod 651 drives the pressing rod 652 to move downward synchronously. The second wedge surface 751 of the pressing rod 652 abuts against the third wedge surface 6521. Then, the linkage block 75 is abutted and moves. The linkage block 75 drives the clamping plate 71 to move synchronously. The clamping plate 71 can clamp the seamless steel pipe located in the material passing groove 171. The clamping plate 71 drives the two guide rods 72 to move synchronously. The second spring 74 is compressed. Subsequently, the inner side wall of the pressing rod 652 fits against the outer side wall of the linkage block 75. At this time, the pressing rod 652 can no longer drive the linkage block 75 to continue moving, and also limits the position of the linkage block 75 at this time, that is, the linkage block 75 cannot move in the reverse direction. Then, the cutting knife 64 can cut the clamped seamless steel pipe. The cut steel pipe can stay in the semi-circular bearing plate 22. Subsequently, the two lifting cylinders 822 drive the limit disc 83 to move upward. The steel pipe in the semi-circular bearing plate 22 loses the limit of the limit disc 83. Then, the steel pipe can enter the rotating ring 21 and then be discharged from the rotating ring 21 into the steel pipe guiding and discharging frame 20. Then, the two lifting cylinders 822 drive the limit disc 83 to move downward, so that the limit disc 83 can limit the steel pipe entering the semi-circular bearing plate 22 again. Immediately afterwards, the lifting electric push rod 62 drives the mounting ring body 65 to move upward. The cutting motor 63 and the cutting knife 64 move upward. The synchronizing rod 651 and the downward moving rod also move upward. After the second wedge surface 751 is docked with the third wedge surface 6521, the elastic force of the second spring 74 drives the guide rod 72 to move in the reverse direction. The guide rod 72 drives the clamping plate 71 to move in the reverse direction. The clamped steel pipe residue loses the clamping force. Then, the residue can automatically slide into the semi-circular bearing plate 22.

[0044] Further, the pressing rod 652 is provided with a first sliding groove 6522 that slidably cooperates with the synchronizing rod 651. First screw holes 6523 are formed on both side walls of the first sliding groove 6522. First screw rods 6524 are screwed into the first screw holes 6523. A plurality of second screw holes 6511 that are equally spaced and cooperate with the first screw rods 6524 are formed on the synchronizing rod 651. The first screw rods 6524 are loosened, so that the pressing rod 652 loses the locking and fixing force. Then, the position of the pressing rod 652 on the synchronizing rod 651 is adjusted. The initial abutting position between the second wedge surface 751 and the third wedge surface 6521 also changes. In this way, the moving distance of the linkage block 75 can also be changed. Then, the first screw rods 6524 are tightened, and the pressing rod 652 is fixed, so that the clamping plate 71 can clamp seamless steel pipes with different diameters.

[0045] Furthermore, the front part of the clamping plate 71 is provided with a rubber layer. Anti-slip lines are provided on the rubber layer. The rubber layer and the anti-slip lines can improve the clamping stability of the seamless steel pipe.

[0046] Afterwards, the rotation mechanism 9 is used to drive the semi-ring bearing plate 22 to rotate. The rotation mechanism 9 includes a second bracket 91, a rotation motor 92 and a driven gear ring 93. The output end of the rotation motor 92 is equipped with a driving gear 94. The second bracket 91 is arranged at the top of the blanking bracket 2. The rotation motor 92 is fixedly connected to the second bracket 91.
