Description

Technical Field

[0001] The invention relates to the technical field of seamless steel pipe cutting, in particular to a steel pipe cutting device for an oxygen pipeline. Background Art

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

[0003] The Chinese invention patent with the publication number CN116713526A discloses a seamless steel pipe cutting device with a quick fixing structure, including a cutting frame, a sliding mechanism is arranged on one side of the upper surface of the cutting frame, a first clamping mechanism is arranged on the sliding mechanism, and a cutting mechanism is installed in the middle of the upper surface of the cutting frame. The seamless steel pipe cutting device with a quick fixing structure, through the use of an auxiliary clamping mechanism, when the seamless steel pipe is 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, the fourth motor is controlled to drive the second bidirectional screw to rotate, and then the second bidirectional screw is used to drive the two second arc-shaped fixing clamps to move inward, and the second arc-shaped fixing clamps are used to clamp the seamless steel pipe near the cutting point.

[0004] However, the above patent still has the following shortcomings in actual use: 1. This patent can prevent the seamless steel pipe from shaking during cutting, but when loading, this patent requires the seamless steel pipe to be placed in the inner cavity of the arc-shaped support plate at the top of the first electric push rod, and then the first electric push rod is started to assist in lifting the seamless steel pipe. When unloading, one end of the cut seamless steel pipe needs to be placed in the inner cavity of the arc-shaped support plate above the second electric push rod. This loading and unloading method is very cumbersome and reduces the cutting efficiency of the steel pipe; 2. The remaining material after cutting cannot be automatically discharged for collection, resulting in workers having to manually collect the remaining material after cutting separately, which is time-consuming and labor-intensive. Summary of the invention

[0033] The present invention adopts an inclined loading machine box 1, so that the seamless steel pipe in the material trough 1211 can move downward by its own gravity. After the material trough 1211 is connected with the steel pipe discharging frame 17, the seamless steel pipe can be automatically discharged into the semi-ring bearing plate 22, and the seamless steel pipe can be cut by the cutting mechanism 6. During cutting, the cutting mechanism 6 can also drive the clamping mechanism 7 to clamp the seamless steel pipe to prevent the seamless steel pipe from shaking. The limit mechanism 8 can release the limit on the cut steel pipe, so that the cut steel pipe can be discharged from the rotating ring 21, and then the steel pipe is led out through the steel pipe guiding discharging frame 20. After the cutting mechanism 6 stops working, the residual material can be limited by the limiting mechanism 8, and then the residual material can be discharged into the residual material guiding discharging frame 10 through the rotating mechanism 9. The residual material can be automatically discharged for collection, thereby improving the efficiency of steel pipe cutting.

[0034] It is worth noting that collection boxes can be provided below the material discharge hopper 4, below the steel pipe guide discharge frame 20, and below the residual material guide discharge frame 10, so as to centrally collect the debris, cut steel pipes, and residual materials.

[0035] When in use, first put multiple seamless steel pipes into the feeding hopper 3. The feeding hopper 3 includes a discharge pipe 31 and two movable side plates 32. The top of the discharge pipe 31 is provided with two side plates 33 symmetrically arranged and integrally connected thereto. Both ends of the inner wall of the side plates 33 are provided with third slide grooves 331. The third slide grooves 331 are provided with a plurality of third screw holes 332 arranged at equal intervals.

The second screw rod 3212 is screwed with the third screw hole 332. The discharge pipe 31 is fixedly connected to the top of the feeding machine box 1, and the discharge pipe 31 is communicated with the feed port 14.

[0036] Loosen the second screw 3212 so that the second screw 3212 can be disengaged from the third screw hole 332 and the fourth screw hole 3211, and the second ear 321 loses its locking and fixing force, that is, the movable side plate 32 loses its locking and fixing force, and the movable side plate 32 can be adjusted, and 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, so that the loading hopper 3 can place seamless steel pipes of different lengths.

[0037] The seamless steel pipes can be arranged in sequence in the discharge pipe 31, and the driving motor 13 drives the rotating shaft 12 and the feeding roller 121 to rotate intermittently. When a feeding trough 1211 is docked with the discharge pipe 31, the seamless steel pipe at the lowest end of the discharge pipe 31 can enter the feeding trough 1211 by its own gravity, and then the seamless steel pipe moves synchronously with the feeding roller 121. The rotating shaft 12 also drives the auxiliary knocking mechanism 5 to work while rotating. The auxiliary knocking mechanism 5 includes a linkage turntable 51 and a lifting guide seat 52. The linkage turntable 51 is provided with a plurality of abutment rods 53 arranged at equal angles along its circumference. One end of the abutment rod 53 is provided with an arc surface 531. The lifting guide seat 52 is provided with a plurality of abutment rods 53 arranged at equal angles along its circumference. A lifting guide rod 54 is slidably provided on the guide seat 52, and a first wedge surface 541 matching the arc surface 531 is provided on the top of the lifting guide rod 54, and a support plate 55 vertically arranged therewith is provided at the bottom end of the lifting guide rod 54, and two vertically arranged first springs 551 are provided on the support plate 55, and one end of the first spring 551 is fixedly connected to the bottom of the lifting guide seat 52, and a mounting plate 56 is provided at one end of the support plate 55, and a plurality of knocking rods 561 are provided on the mounting plate 56, and the linkage turntable 51 is fixedly connected to the other end of the rotating shaft 12, and the lifting guide seat 52 is fixedly connected to the front outer wall of the loading box 1, and the mounting plate 56 is located directly below the bottom of the loading box 1.

[0038] After the rotating shaft 12 rotates, it not only drives the feeding roller 121 to rotate, but also drives the linkage rotating disk 51 to rotate, and all the abutting rods 53 on the linkage rotating disk 51 also rotate synchronously, and the arc surface 531 on the abutting rod 53 can gradually abut against the first wedge surface 541, and then the abutting rod 53 transmits the rotational force to the lifting guide rod 54, and the lifting guide rod 54 moves downward on the lifting guide seat 52, and 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, and the knocking rod 561 also moves downward with the mounting plate 56 The support plate 55 drives the mounting plate 56, the lifting guide rod 54 and all the knocking rods 561 to move up synchronously, and the knocking rods 561 knock on the bottom of the feeding box 1, so that the impurities carried on the outer wall of the seamless steel pipe in the feeding trough 1211 can be separated from the seamless steel pipe, and then the impurities can be discharged into the unloading hopper 4 through the discharge port 15. Of course, the knocking force can also make it easier for the seamless steel pipe to slide by its own gravity.

[0039] After that, the feeding trough 1211 gradually docks with the steel pipe discharging frame 17, and the seamless steel pipe in the feeding trough 1211 moves by its own weight, and then the seamless steel pipe slides into the feeding trough 171, and then the seamless steel pipe can slide onto the semi-ring bearing plate 22, and the position of the seamless steel pipe entering the semi-ring bearing plate 22 is limited by the limiting mechanism 8, and the limiting mechanism 8 includes a push electric push rod 81, a mounting rod 82 and a limiting plate 83 matching the rotating ring 21, and the top of the mounting rod 82 is A guide slider 821 is provided at the middle end, and vertically arranged lifting cylinders 822 are provided on both sides of the guide slider 821. First ears 831 are provided on the two outer walls of the limiting plate 83. A second slide groove 221 is provided at the bottom of the semi-ring bearing plate 22. The push electric push rod 81 is fixedly connected to the bottom of the semi-ring bearing plate 22. The guide slider 821 is slidably set in the second slide groove 221, and the output ends of the two lifting cylinders 822 are fixedly connected to the bottoms of the two second ears 321 respectively.

[0040] The limiting plate 83 can block the seamless steel pipe, and by pushing the electric push rod 81 to drive the installation rod 82 to move, the installation rod 82 can drive the lifting cylinder 822 and the limiting plate 83 to move synchronously, so that the position of the limiting plate 83 can be adjusted in the semi-ring supporting plate 22, that is, the cutting length of the seamless steel pipe is changed, and then 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. A mounting ring 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 discharge frame 17. The lifting electric push rod 62 is vertically fixedly connected to the top of the first bracket 61. The cutting motor 63 is arranged in the mounting ring 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, and two guide rods 72 are provided on the back of the clamping plate 71. A limit plate 73 is provided at one end of the guide rod 72. A second spring 74 is sleeved on the guide rod 72. A linkage block 75 is provided between the two guide rods 72. A second wedge surface 751 is provided at one end of the linkage block 75. A synchronization rod 651 is provided on the outer wall of the mounting ring body 65. A downward pressure rod 652 is detachably connected to the synchronization rod 651. A third wedge surface 6521 that cooperates with the second wedge surface 751 is provided at the bottom of the downward pressure rod 652. An embedded groove is provided on the inner wall of the rotating cavity 11 and the steel pipe discharging frame 17. Guide holes that cooperate with the guide rods 72 are provided on the outer walls of the feeding machine box 1 and the steel pipe discharging frame 17. A sliding hole that slidably cooperates with the linkage block 75 is also provided on the outer wall of the steel pipe discharging frame 17. The clamping plate 71 is slidably arranged in the embedded groove, and the downward pressure rod 652 is located directly above the linkage block 75.

[0043] The mounting ring 65 is driven downward by the lifting electric push rod 62, and the mounting ring 65 drives the cutting motor 63 and the cutting knife 64 to move downward. When the mounting ring 65 moves downward, it also drives the synchronous rod 651 to move downward, and the synchronous rod 651 drives the pressing rod 652 to move downward synchronously, and the second wedge surface 751 of the pressing rod 652 abuts against the third wedge surface 6521, and then the linkage block 75 is abutted to move, and the linkage block 75 drives the clamping plate 71 to move synchronously, and the clamping plate 71 can clamp the seamless steel pipe located in the material trough 171, and the clamping plate 71 drives the two guide rods 72 to move synchronously, and the second spring 74 is compressed, and then the inner side wall of the pressing rod 652 is fitted with the outer side wall of the linkage block 75, and at this time, the pressing rod 652 can no longer drive the linkage block 75 to continue to move, and also limits the position of the linkage block 75 at this time, that is, the linkage block 75 cannot move in the opposite direction, and then the cutting knife 64 can cut the clamped seamless steel pipe. The cut steel pipe can be retained in the semi-ring bearing plate 22, and then the two lifting cylinders 822 drive the limit plate 83 to move up, and the steel pipe located in the semi-ring bearing plate 22 loses the limit of the limit plate 83, and then the steel pipe can enter the rotating ring 21, and then be discharged from the rotating ring 21 into the steel pipe guide discharge frame 20; then the two lifting cylinders 822 drive the limit plate 83 to move down, so that the limit plate 83 can again adjust the steel pipe entering the semi-ring bearing plate 22 The limiting operation is performed, and then the lifting electric push rod 62 drives the installation ring body 65 to move upward, the cutting motor 63 and the cutting knife 64 move upward, and the synchronization 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 opposite direction, and the guide rod 72 drives the clamping plate 71 to move in the opposite direction. The clamped steel pipe residue loses the clamping force, and then the residue can automatically slide into the semi-ring bearing plate 22.

[0044] Furthermore, the lower pressure rod 652 is provided with a first sliding groove 6522 that slidably cooperates with the synchronization rod 651, and first screw holes 6523 are provided on the groove walls on both sides of the first sliding groove 6522, and a first screw rod 6524 is screwed into the first screw hole 6523, and a plurality of second screw holes 6511 that are evenly spaced and cooperate with the first screw rod 6524 are provided on the synchronization rod 651. Loosening the first screw rod 6524 causes the lower pressure rod 652 to lose its locking force, and then adjusting the position of the lower pressure rod 652 on the synchronization rod 651, the initial contact position of the second wedge surface 751 and the third wedge surface 6521 is also changed, so that the moving distance of the linkage block 75 can also be changed, and then tightening the first screw rod 6524, the lower pressure rod 652 is fixed, so that the clamping plate 71 can clamp seamless steel pipes of different diameters.

[0045] Furthermore, a rubber layer is provided at the front of the clamping plate 71, and anti-skid patterns are provided on the rubber layer. The rubber layer and the anti-skid patterns can improve the clamping stability of the seamless steel pipe.

[0046] Then, the semi-ring bearing plate 22 is driven to rotate by the rotating mechanism 9. The rotating mechanism 9 includes a second bracket 91, a rotating motor 92 and a driven ring gear 93. A driving gear 94 is installed at the output end of the rotating motor 92. The second bracket 91 is arranged on the top of the unloading bracket 2.
