Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe cutting equipment, and in particular to fully automatic seamless steel pipe cutting equipment. Background Technology

[0002] Seamless steel pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is made from a single piece of metal and has no seams on its surface. Its cross-section is circular or other shapes (such as square, rectangular, etc.). It has high strength and pressure resistance. Seamless steel pipe cutting equipment is a processing equipment for cutting seamless steel pipes.

[0003] When cutting seamless steel pipes using cutting equipment, the steel pipe enters the equipment and the output length of the steel pipe near the cutting saw is controlled by the pushing mechanism on the equipment. Then, the cutting saw cuts the pipe. When the length of the steel pipe to be cut is long, the part of the steel pipe protruding from the surface of the equipment will fall due to gravity, causing the angle between the steel pipe and the equipment to deviate. This also causes uneven force at the contact point between the steel pipe surface and the cutting saw, resulting in a decrease in the cutting effect of the cutting equipment. Utility Model Content

[0021] Example 1, as Figure 1-3As shown, the fully automatic seamless steel pipe cutting equipment includes a machine body 1. A bearing plate 3 is fixedly connected to the top of the machine body 1. A base 5 is slidably mounted on one side of the top of the machine body 1. A cutting head 6 is mounted on the outer surface of the base 5. A hydraulic lifting assembly for driving the cutting head 6 to rise and fall is installed inside the base 5. A cutting saw and a reduction motor for driving the cutting saw to rotate are mounted on the outer surface of the cutting head 6. A first hydraulic rod 4 is mounted on the top of the machine body 1 near the base 5. The output rod of the first hydraulic rod 4 is fixedly connected to one side of the base 5. A positioning plate 8 is slidably mounted on the top of the machine body 1 near the bearing plate 3. A through groove is opened on the outer surface of the positioning plate 8. A second hydraulic rod 7 is mounted on the top of the machine body 1 near the positioning plate 8. The output rod of the second hydraulic rod 7 is connected to the positioning plate 8. The top of plate 8 is fixedly connected, and the top of the machine body 1 is fixedly connected to a frame 9. A rotatable lead screw is installed inside the frame 9. A drive motor for driving the lead screw is installed at one end of the frame 9. A support plate 10 is slidably connected to the outer surface of the frame 9. One end of the inner wall of the support plate 10 is threadedly connected to the outer surface of the lead screw inside the frame 9. A third hydraulic rod 11 is installed on one side of the top of the support plate 10. A pressure plate 12 is fixedly connected to the output rod of the third hydraulic rod 11. The two ends of the pressure plate 12 slide on both sides of the support plate 10. A support device 2 is installed at the end of the machine body 1 near the bearing plate 3 to support the seamless steel pipe extending out of the machine body 1. When cutting the seamless steel pipe using the cutting equipment, the seamless steel pipe is placed at the end of the machine body 1 away from the placement plate and the seamless steel pipe... One end rests on the outer surface of the pallet 10. Then, the operating parameters of the machine body 1 are adjusted via the control box on one side of the machine body 1. The third hydraulic rod 11 at the top of the pallet 10 extends, controlling the pressure plate 12 to move downwards and press it against the top of the steel pipe. Then, the drive motor at one end of the frame 9 rotates the screw, controlling the pallet 10 to move towards the bearing plate 3, so that part of the steel pipe surface enters the bearing plate 3. The length of the steel pipe extending out of the machine body 1 is controlled to adjust the cutting length of the steel pipe. Then, the third hydraulic rod 11 retracts, causing the pressure plate 12 to rise away from the surface of the steel pipe. The second hydraulic rod 7 extends, pushing the positioning plate 8 downwards and pressing it against the surface of the steel pipe. The drive motor at one end of the rod rotates again, causing the screw to rotate, moving the pallet 10 away from the bearing plate 3. The machine prepares to control the steel pipe to move again. At this time, the first hydraulic rod 4 retracts, controlling the machine base 5 to move towards the support plate 3, so that the cutting saw approaches the steel pipe, enters the through groove on the outer surface of the positioning plate 8, and stops at a suitable cutting position. The reduction motor on the outer surface of the cutting head 6 drives the cutting saw to rotate and cut the steel pipe. During the cutting process, the hydraulic lifting component inside the machine base 5 operates, controlling the cutting head 6 to slowly descend and adjust the height of the cutting saw to cut the steel pipe. After the cutting is completed, the cutting head 6 is controlled to rise, and the first hydraulic rod 4 extends to push the machine base 5 away from the support plate 3. The third hydraulic rod 11 at the top of the support plate 10 will operate again to extend and control the pressure plate 12 to move downward, pressing the pressure plate 12 onto the top of the steel pipe. The second hydraulic rod 7 retracts, driving the positioning plate 8 away from the surface of the steel pipe.Subsequently, the drive motor at one end of the frame 9 operates, causing the lead screw to rotate and controlling the support plate 10 to move towards the bearing plate 3. This pushes the cut steel pipe through the uncut steel pipe and outputs it through one end of the machine body 1. Repeating this step allows for multiple cuts of the steel pipe.

[0022] Reference Figure 1-5 As shown in this embodiment: the support device 2 includes a rotating shaft 21 and an electric push rod 23. The two ends of the rotating shaft 21 are rotatably connected to one end of the machine body 1. A support plate 22 is fixedly connected to the outer surface of the rotating shaft 21. A groove 24 is provided at the bottom end of the support plate 22. The electric push rod 23 is rotatably installed at one end of the machine body 1 near the bearing plate 3. The output rod of the electric push rod 23 is rotatably connected to a T-shaped block 25. The top end of the T-shaped block 25 slides on the inner wall of the groove 24. When using the cutting equipment, the part of the steel pipe that protrudes from the machine body 1 at one end of the bearing plate 3 will rest on the outer surface of the support plate 22. The support plate 22 supports the bottom of the steel pipe to prevent the angle of the steel pipe from deflecting during the cutting process. When the steel pipe is output after cutting, the electric push rod 23 is operated to retract and pull the T-shaped block 25 to slide towards the machine body 1 on the inner wall of the groove 24. At the same time, the T-shaped block 25 will slide on the electric push rod 23. The output rod of 3 rotates outward, and the T-shaped block 25 slides on the inner wall of the slide groove 24, pulling the support plate 22 downward through the rotating shaft 21, so that the support plate 22 tilts, allowing the cut steel pipe to be output more quickly. After the steel pipe is output, the electric push rod 23 is operated to extend and control the T-shaped block 25 to slide away from the machine body 1 on the inner wall of the slide groove 24. The T-shaped block 25 pushes the support plate 22 to rotate upward to an angle parallel to the bearing plate 3. By setting the support device 2, by installing the rotatable support plate 22 at one end of the machine body 1 near the bearing plate 3, the support plate 22 supports the part of the steel pipe that extends out of the machine body 1 when cutting the steel pipe, avoiding the tilting of the steel pipe during the cutting process and affecting the cutting effect. After the cutting is completed, the electric push rod 23 is operated to control the rotation and tilting of the support plate 22, so that the steel pipe can be output more smoothly and quickly, improving the stability of the cutting equipment during use.

[0023] Reference Figure 2-5 As shown in this embodiment: a protruding strip 27 is fixedly connected to one side of the top of the support plate 22. The protruding strip 27 is made of rubber. When the electric push rod 23 controls the support plate 22 to rotate downward, the rubber protruding strip 27 near the top of the rotating shaft 21 of the support plate 22 can apply a pushing force to the cut steel pipe to assist the output of the steel pipe.

[0024] Reference Figure 2-6As shown in this embodiment: the outer surface of the support plate 22 is provided with an adjustment component 26 that can adjust the length of the support plate 22 extending out of the machine body 1. The adjustment component 26 includes a sliding plate 262. A rectangular groove 261 is opened at the top of the support plate 22. The sliding plate 262 slides on the inner wall of the rectangular groove 261. A sliding rod 263 is fixedly connected to one side of the sliding plate 262. The sliding rod 263 slides on one side of the inner wall of the rectangular groove 261. A screw 264 is threadedly connected to the bottom of the inner wall of the sliding rod 263. A pressure block 265 is rotatably connected to the top of the screw 264. When using the cutting equipment, the sliding plate is pushed at the top of the support plate 22. 262 can control the sliding plate 262 to slide on the inner wall of the rectangular groove 261, controlling the sliding plate 262 to extend out of or retract into the rectangular groove 261. At the same time, the sliding rod 263 will slide on one side of the inner wall of the rectangular groove 261. After the position of the sliding plate 262 is adjusted, the screw 264 at the bottom of the sliding rod 263 is rotated to control the screw 264 to move upward on the inner wall of the sliding rod 263, so that the top of the pressure block 265 is pressed against the bottom surface of the support plate 22, fixing the position of the sliding plate 262 inside the rectangular groove 261 and the total length of the sliding plate 262 and the support plate 22, thereby improving the flexibility of the support device 2 when in use.

[0025] Reference Figure 2-6 As shown in this embodiment: an operating block 266 is fixedly connected to the bottom end of the screw 264. The bottom end of the operating block 266 is provided with a rotatable protrusion. Holding the outside of the protrusion at the bottom end of the operating block 266 allows for easier rotation of the operating block 266 to control the screw 264 to rotate and adjust the position of the pressure block 265. The top end of the pressure block 265 is provided with several rubber anti-slip strips 267. The anti-slip strips 267 are linearly distributed on the surface of the pressure block 265. By providing rubber anti-slip strips 267, the friction between the top end of the pressure block 265 and the bottom end surface of the support plate 22 can be increased, thereby improving the stability of the pressure block 265 when pressing against the surface of the support plate 22 to fix the position of the slide plate 262.

[0026] Working principle: When cutting seamless steel pipes using the cutting equipment, first push the slide plate 262 at the top of the support plate 22 to control the slide plate 262 to slide on the inner wall of the rectangular groove 261, controlling the slide plate 262 to extend out of or retract into the rectangular groove 261. At the same time, the slide rod 263 will slide on one side of the inner wall of the rectangular groove 261. After the position of the slide plate 262 is adjusted, rotate the screw 264 at the bottom of the slide rod 263 to control the screw 264 to move upward on the inner wall of the slide rod 263, so that the top of the pressure block 265 is pressed against the bottom surface of the support plate 22, fixing the position of the slide plate 262 inside the rectangular groove 261 and the total length of the slide plate 262 and the support plate 22. Then, place the seamless steel pipe on the end of the machine body 1 away from the placement plate and let one end of the seamless steel pipe rest on the support. The outer surface of plate 10 is adjusted via the control box on one side of the machine body 1. The third hydraulic rod 11 at the top of the support plate 10 will extend to control the pressure plate 12 to move downward, pressing the pressure plate 12 onto the top of the steel pipe. Then, the drive motor at one end of the frame 9 will rotate the screw to control the support plate 10 to move towards the bearing plate 3, so that part of the steel pipe surface enters the bearing plate 3. The length of the steel pipe extending out of the machine body 1 is controlled to adjust the cutting length of the steel pipe. The part of the steel pipe that is exposed on the bearing plate 3 will rest on the outer surface of the support plate 22, which will support the bottom of the steel pipe. Then, the third hydraulic rod 11 will retract to drive the pressure plate 12 to rise away from the surface of the steel pipe. The second hydraulic rod 7 will extend to push the positioning plate 8 downward to press on the surface of the steel pipe. On the other hand, the drive motor at one end of the machine rod operates again, driving the lead screw to rotate, causing the support plate 10 to move away from the bearing plate 3, preparing to control the steel pipe to move again. At this time, the first hydraulic rod 4 operates to retract, controlling the machine base 5 to move towards the bearing plate 3, so that the cutting saw approaches the steel pipe, enters the through groove on the outer surface of the positioning plate 8, and stops at a suitable cutting position. The reduction motor on the outer surface of the cutting head 6 operates to drive the cutting saw to rotate and cut the steel pipe. During the cutting process, the hydraulic lifting component inside the machine base 5 operates to control the cutting head 6 to slowly descend and adjust the height of the cutting saw to cut the steel pipe. After the cutting is completed, the cutting head 6 is controlled to rise and the first hydraulic rod 4 is operated to extend and push the machine base 5 away from the bearing plate 3. The third hydraulic rod 11 at the top of the support plate 10 will operate again to extend and control the pressure plate 12 to move downward. The pressure plate 12 is pressed against the top of the steel pipe. The second hydraulic rod 7 retracts, causing the positioning plate 8 to move away from the surface of the steel pipe. At the same time, the electric push rod 23 retracts, pulling the T-shaped block 25 to slide towards the machine body 1 on the inner wall of the slide groove 24. Simultaneously, the T-shaped block 25 rotates outside the output rod of the electric push rod 23. The sliding of the T-shaped block 25 on the inner wall of the slide groove 24 pulls the support plate 22 to rotate downward through the rotating shaft 21, causing the support plate 22 to tilt. Then, the drive motor at one end of the frame 9 drives the screw to rotate, controlling the support plate 10 to move towards the bearing plate 3. Through the uncut steel pipe, the cut steel pipe is pushed out through one end of the machine body 1. After the steel pipe is output, the electric push rod 23 extends again, controlling the T-shaped block 25 to slide away from the machine body 1 on the inner wall of the slide groove 24.By pushing the support plate 22 upwards using the T-block 25 until it is parallel to the bearing plate 3, this step can be repeated to cut the steel pipe multiple times.
