Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe processing technology, specifically a cutting machine for seamless steel pipes. Background Technology

[0002] Seamless steel pipes are used in various lengths. Newly produced stainless steel seamless pipes are too long to meet people's needs, so they need to be cut into certain lengths before they can be used. However, existing cutting devices generate a lot of iron filings that fly everywhere when cutting steel pipes, making it very troublesome for workers to clean up and affecting the workshop environment. At the same time, the cutting wheel will wear down during cutting, and the dust generated during the wear is light, which makes it easy to cause dust to be stirred up during cleaning, increasing the difficulty of collection. Workers who are exposed to this dust for a long time are prone to pneumoconiosis.

[0003] Therefore, Chinese Patent Publication No. CN 218504182 U discloses a cutting device for seamless stainless steel pipes, including a cutting box with an inlet and an outlet, and an observation window installed on the front face of the cutting box. Both the inlet and outlet of the cutting box are equipped with clamping mechanisms for holding the seamless steel pipe, and the cutting box contains a cutting mechanism for cutting the seamless steel pipe. This utility model achieves the cutting of seamless steel pipes through the cutting mechanism. The cutting box also prevents the problem of cutting chips falling to the ground and affecting the environment, a problem common in traditional cutting operations. Furthermore, the cutting chips and dust from grinding wheel wear are bound together by the cooling water, preventing them from easily scattering during recovery and reducing the difficulty of chip recovery. In addition, the clamping mechanism clamps and fixes the seamless steel pipe, preventing it from shaking during cutting and further improving the cutting quality of the equipment.

[0004] However, when the stainless steel seamless pipe cutting device is in use, the recycling component only pushes the iron filings by rotating the recycling plate. Iron filings are easily left in the corners and gaps inside the cutting box. Especially when there is a gap between the recycling plate and the box wall, it is difficult to clean them completely. The residual iron filings may be mixed into the subsequent cutting process, scratching the surface of the steel pipe or affecting the life of the cutting tool, thus causing defects in the use of the device.

[0016] This invention provides a cutting machine for seamless steel pipes. Compared with the prior art, it has the following advantages:

[0017] 1. This cutting machine for seamless steel pipes achieves dual filtration of used water by setting up a connecting frame, connecting cylinder, magnet, geared motor, housing and filter plate. The rotating connecting frame causes the magnet to rotate and attract iron filings in the water.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-7This utility model provides a technical solution: a cutting machine for seamless steel pipes, including a housing 1. A partition 2 is fixedly connected inside the housing 1 to divide the space within the housing 1. A filter plate 3 is fixedly connected inside the housing 1 and at the bottom of the partition 2 to filter the water inside the housing 1. A connecting frame 4 is rotatably connected to the bottom of the housing 1. Connecting cylinders 5 are symmetrically and detachably connected inside the connecting frame 4. Rotating the connecting frame 4 causes the connecting cylinders 5 to rotate. A magnet 6 is detachably connected inside the connecting cylinders 5. Rotating the connecting cylinders 5 with the magnet 6 attracts iron filings in the water inside the housing 1. A connecting cover 8 is rotatably connected to one end of the magnet 6. Moving the connecting cover 8 moves the magnet 6. The outer side of the connecting cover 8 is threadedly connected to the connecting cylinder 5, better securing the magnet 6 inside the connecting cylinder 5 and facilitating its removal. A first connecting pipe 20 is fixedly connected inside the housing 1 and below the filter plate 3. The end of the first connecting pipe 20 away from the housing 1 is fixedly connected to the partition 2. Water from the top of the partition 2 flows down the first connecting pipe 2... A connecting pipe 20 enters the bottom of the housing 1. A second connecting pipe 25 is fixedly connected inside the housing 1 and above the filter plate 3. A water pump 24 is fixedly connected to the top of the housing 1. The end of the second connecting pipe 25 away from the housing 1 is fixedly connected to the water pump 24. After the water pump 24 is turned on, it draws the filtered water above the filter plate 3 through the second connecting pipe 25. A spray nozzle 26 is fixedly connected inside the housing 1. A cooler 23 is fixedly connected to the end of the water pump 24 away from the second connecting pipe 25. The cooler 23 cools the water. The cooling unit 23 extends through one side of the housing 1 and into the interior of the housing 1, where it is fixedly connected to the nozzle 26. Cooled water enters the nozzle 26 and sprays onto the cutting blade 21 to cool it down. A cylinder 22 is fixedly connected to the top of the housing 1. The output end of the cylinder 22 passes through the top of the housing 1 and is fixedly connected to the cutting blade 21. When the cylinder 22 is turned on, it moves the cutting blade 21. One side of the cutting blade 21 is fixedly connected to the output end of the motor. When the motor is turned on, it rotates the cutting blade 21.

[0029] Furthermore, symmetrical placement holes are provided on both sides of the box 1 to better accommodate the seamless steel pipe. Connecting plates 13 are fixedly connected to both sides of the box 1. A first mounting plate 14 is fixedly connected to the top end of the connecting plate 13, and a second mounting plate 16 is fixedly connected to the top end of the connecting plate 13 away from the first mounting plate 14. A second arc-shaped plate 18 is fixedly connected between the first mounting plate 14 and the second mounting plate 16. The seamless steel pipe is placed on top of the second arc-shaped plate 18. Sliding grooves are provided at both ends of the second arc-shaped plate 18. A first arc-shaped plate 17 is slidably connected to one side of the second mounting plate 16, and a sliding rod is fixedly connected to one side of the second mounting plate 16. One end of the first arc-shaped plate 17 is slidably connected to the sliding rod. The width of the first arc-shaped plate 17 is smaller than the width of the second arc-shaped plate 18. When the seamless steel pipe is small, both ends of the first arc-shaped plate 17 enter the sliding groove until they contact the top of the seamless steel pipe to fix it.

[0030] Furthermore, symmetrical placement holes are provided on both sides of the box 1 to better accommodate the seamless steel pipe. Connecting plates 13 are fixedly connected to both sides of the box 1. A first mounting plate 14 is fixedly connected to the top end of the connecting plate 13, and a second mounting plate 16 is fixedly connected to the top end of the connecting plate 13 away from the first mounting plate 14. A second arc-shaped plate 18 is fixedly connected between the first mounting plate 14 and the second mounting plate 16. The seamless steel pipe is placed on the top of the second arc-shaped plate 18. Sliding grooves are provided at both ends of the second arc-shaped plate 18. A first arc-shaped plate 17 is slidably connected to one side of the second mounting plate 16. The width of the first arc-shaped plate 17 is smaller than the width of the second arc-shaped plate 18. When the seamless steel pipe is small, both ends of the first arc-shaped plate 17 enter the sliding grooves until they contact the top of the seamless steel pipe, thus fixing the seamless steel pipe.

[0031] Furthermore, a fixed frame 10 is slidably connected inside the connecting frame 4. Springs 11 are fixedly connected between the two sides of the fixed frame 10 and the inner wall of the connecting frame 4. When the fixed frame 10 moves, it compresses the springs 11. The springs 11 generate elastic force when compressed. When the springs 11 lose their compressive force, they return to their original position with the fixed frame 10 under the action of the elastic force. Connecting holes 7 are symmetrically opened on one side of the connecting cover 8. The connecting holes 7 are used in conjunction with the fixed frame 10. Both ends of the fixed frame 10 enter the connecting holes 7, which strengthens the connection between the connecting cover 8 at one end of the connecting cylinder 5 and the connecting frame 4.

[0032] Furthermore, the connecting cover 8, the connecting frame 4, and the fixing frame 10 are detachably connected by the second bolt 12. The second bolt 12 gradually enters the fixing frame 10, the connecting frame 4, and the connecting cover 8, and takes the fixing frame 10 into the connecting hole 7 to fix the position of the fixing frame 10.

[0033] Furthermore, a geared motor 19 is fixedly connected to one side of the housing 1. The output end of the geared motor 19 passes through one side of the housing 1 and is fixedly connected to the connecting frame 4. When the geared motor 19 is turned on, it drives the connecting frame 4 to rotate.

[0034] Furthermore, the end of the connecting cylinder 5 away from the second bolt 12 is detachably connected to the connecting frame 4 via the first bolt 9, which facilitates the disassembly of the connecting cylinder 5.

[0035] Furthermore, a lead screw 15 is rotatably connected to one side of the first mounting plate 14, and the end of the first arc-shaped plate 17 away from the second mounting plate 16 is threadedly connected to the lead screw 15. The lead screw 15 rotates, causing the first arc-shaped plate 17 to move.

[0036] Furthermore, a first door panel 28 is hinged to the top of one side of the housing 1. An observation window is installed on one side of the first door panel 28 to facilitate viewing the interior of the housing 1. A second door panel 29 is hinged to one side of the housing 1 between the first door panel 28 and the filter plate 3. A third door panel 30 is hinged to one side of the housing 1 below the filter plate 3 to facilitate disassembly of the connecting cylinder 5. A sealing layer 27 is provided on one side of the first door panel 28, the second door panel 29 and the third door panel 30 to enhance the sealing of the housing 1 and prevent water from flowing out of the housing 1.

[0037] In use, pour water into the tank 1 through the inlet on one side, submerging the filter plate 3. Insert the seamless steel pipe into the tank 1 through the placement holes on both sides, ensuring that the bottom ends of the seamless steel pipe contact the second arc plate 18. Rotate the lead screw 15, which moves the first arc plate 17 closer to the seamless steel pipe until it contacts it. Fix both ends of the seamless steel pipe between the first arc plate 17 and the second arc plate 18 to prevent the seamless steel pipe from shaking during cutting and affecting the cutting effect. Turn on the motor on one side of the cylinder 22 and the cutting blade 21. The motor drives the cutting blade... 21 rotates, and cylinder 22 adjusts the position of cutting blade 21, causing it to gradually approach the seamless steel pipe for cutting. Simultaneously, water pump 24 and drive reduction motor 19 are activated. Water pump 24 pumps water from the housing 1 to the cooler 23 via the second connecting pipe 25. The cooler 23 cools the water, which is then sent to nozzle 26. Nozzle 26 sprays water to cool the cutting blade 21, preventing it from overheating and shortening its lifespan. The water sprayed from nozzle 26 flows along the first connecting pipe 20 to the bottom of housing 1 and is positioned at filter plate 3. Below, the drive reduction motor 19 starts and rotates the connecting frame 4. The connecting frame 4 rotates the connecting cylinders 5 on both sides and the magnet 6, causing the iron filings in the water to be attracted to the outside of the connecting cylinders 5. The filter plate 3 filters the water, and the filtered water is discharged above the filter plate 3 for reuse, thus saving water resources. When it is necessary to clean the iron filings, open the third door panel 30 to drain the water in the box 1. Turn the first bolt 9 to disconnect one end of the connecting cylinder 5 from the connecting frame 4. Turn the second bolt 12, and the second bolt 12 gradually moves away from the inside of the connecting cover 8, the connecting frame 4 and the fixing frame 10, springing back. When the spring 11 loses its compressive force, under the action of elasticity, the spring 11, along with the fixing bracket 10, leaves the connecting hole 7, releasing the restriction on the connecting cover 8. The connecting cylinder 5 and the connecting cover 8 are then removed from the connecting bracket 4. The connecting bracket 4 is placed in the container for recycling iron filings. The connecting cover 8 is rotated, and under the action of the threads, the connecting cover 8 carries the magnet 6 away from the connecting cover 8. Moving the connecting cover 8 pulls the magnet 6 out of the connecting cylinder 5 as a whole. The iron filings on the outside of the connecting cylinder 5 lose their magnetic attraction and fall off the outside of the connecting cylinder 5. Finally, the remaining iron filings on the outside of the connecting cylinder 5 are cleaned, completing the recycling of iron filings.
