Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production equipment, in particular to a high-efficiency cutting device for producing plastic-coated anti-corrosion steel pipes. Background Art

[0002] The main feature of plastic-coated anti-corrosion steel pipe is that a special anti-corrosion coating is coated on the surface of the steel pipe to enhance the corrosion resistance of the steel pipe. This coating is usually composed of materials such as polyethylene, polyvinyl chloride or epoxy resin. Plastic-coated anti-corrosion steel pipe is suitable for various media transportation pipelines, such as water, oil, natural gas, chemicals, etc., as well as structural components in industrial facilities that require corrosion resistance. During the production process of plastic-coated anti-corrosion steel pipe, the steel pipe needs to be cut.

[0003] At present, in order to ensure that the length of the steel pipe is consistent each time it is cut, a baffle is usually installed on the cutting table, and the baffle is set in a fixed position. By making one end of the steel pipe rest against the baffle, the length of the cut steel pipe can be ensured to be consistent. However, the baffle is usually installed with bolts. As a result, when cutting steel pipes of other lengths, it takes a long time to adjust the position of the baffle, which is more troublesome to use.

[0004] After the steel pipe is cut, workers need to remove it from the cutting table. This process not only consumes physical strength, but also consumes a certain amount of time, which in turn affects production efficiency. Utility Model Content

[0022] like Figures 1 to 4As shown, a connecting shaft 2 is rotatably installed between the two side panels 1, and three first arc-shaped brackets 3 are installed in a coaxial array on the outer surface of the connecting shaft 2. Placing the steel pipe in the first arc-shaped bracket 3 can limit the steel pipe. A first servo motor 4 is installed on the outer surface of one side panel 1, and the end of the output shaft of the first servo motor 4 is connected to the connecting shaft 2. When the first servo motor 4 is started to drive the connecting shaft 2 to rotate 120 degrees, the cut steel pipe in the first arc-shaped bracket 3 can be flipped to one side to make it fall. Then the first arc-shaped bracket 3 on the other side is rotated to the top and the next cutting can be carried out. Baffles 5 are provided inside the three first arc-shaped brackets 3, and an inner groove 6 is provided inside the connecting shaft 2. An adjustment mechanism 12 that can adjust the position of the three baffles 5 at the same time is provided inside the inner groove 6. The position of the baffle 5 can be quickly adjusted through the adjustment mechanism 12, which improves the flexibility of use, reduces the time required to adjust the baffle 5, and improves work efficiency. A bracket 7 is installed on the upper surface of the side panel 1 away from the first servo motor 4, and a first electric push rod 8 is installed on the top of the bracket 7. A rotating motor 9 is installed at the end of the telescopic end of the first electric push rod 8, and a cutting disc 10 is installed at the end of the output shaft of the rotating motor 9. The first electric push rod 8 drives the rotating motor 9 and the cutting disc 10 to descend to cut the steel pipe.

[0023] The front and rear sides of the bracket 7 are both provided with curved pressure plates 11. The side surface of the bracket 7 is provided with a lifting mechanism 18 that can simultaneously drive the two curved pressure plates 11 to rise and fall. The lifting mechanism 18 drives the two curved pressure plates 11 to fix the outer surfaces of both sides of the steel pipe cutting area, which can improve the stability of the steel pipe during cutting and thus improve the cutting quality. A second curved bracket 23 is installed on the outer surface of the side panel 1 away from the first servo motor 4. A support seat 24 is installed at the bottom of the second curved bracket 23. The second curved bracket 23 is provided to support the uncut portion of the steel pipe. After the steel pipe is cut, the steel pipe on the second curved bracket 23 is pushed forward and pressed against the baffle 5, and the next cut can be immediately performed.

[0024] Slide grooves 25 are provided on the inner walls on both sides of the bracket 7, and sliders 26 are connected to the outer surfaces on both sides of the rotary motor 9. The ends of the sliders 26 are arranged in the slide grooves 25. Through the arrangement of the slide grooves 25 and the sliders 26, the stability of the rotary motor 9 can be improved when the first electric push rod 8 drives the rotary motor 9 to rise and fall, thereby ensuring the cutting quality of the steel pipe.

[0025] The adjusting mechanism 12 includes a second servo motor 13 installed on the inner wall of one side of the inner groove 6, and the end of the output shaft of the second servo motor 13 is connected to a threaded rod 14, and the end of the threaded rod 14 is rotatably connected to the inner wall of the other side of the inner groove 6, and a nut 15 is installed on the outer surface of the threaded rod 14. The interior of the three first arc-shaped brackets 3 is provided with a through slot 16, and the through slot 16 is connected to the inner groove 6. Three connecting rods 17 are installed in a coaxial array on the outer surface of the nut 15, and the end of the connecting rod 17 passes through the through slot 16 and is connected to the baffle 5. When the position of the baffle 5 needs to be adjusted, the second servo motor 13 can be started, and the second servo motor 13 drives the threaded rod 14 to rotate. Due to the limiting effect of the connecting rod 17 and the through slot 16 acting on the nut 15, the nut 15 can move along the length direction of the threaded rod 14 and drive the three baffles 5 to move at the same time, thereby achieving the purpose of adjusting the position of the baffle 5.

[0026] The lifting mechanism 18 includes an upper fixed plate 19 installed on the side surface of the bracket 7, and a second electric push rod 20 is installed on the upper surface of the upper fixed plate 19. A U-shaped plate 21 is installed at the end of the telescopic end of the second electric push rod 20, and the two ends of the U-shaped plate 21 are respectively arranged on the front and rear sides of the bracket 7. The lower surfaces of both ends of the U-shaped plate 21 are connected with connecting rods 22, and the ends of the connecting rods 22 are connected to the arc-shaped pressure plate 11. Before cutting the steel pipe, the second electric push rod 20 is started first, and the telescopic end of the second electric push rod 20 drives the U-shaped plate 21 to descend. Through the connecting action of the connecting rod 22, the two arc-shaped pressure plates 11 can be driven to descend at the same time and pressed against the outer surface of the steel pipe, thereby achieving the purpose of fixing the steel pipe. A lower fixing block 27 is installed on the side surface of the bracket 7, and the upper surface of the lower fixing block 27 is connected to a limiting rod 28, and the end of the limiting rod 28 passes through the interior of the U-shaped plate 21 and is connected to the upper fixing plate 19. Through the arrangement of the lower fixing block 27 and the limiting rod 28, the force at the connection between the telescopic end of the second electric push rod 20 and the U-shaped plate 21 can be shared, thereby improving the reliability of the connection relationship between the U-shaped plate 21 and the second electric push rod 20, and ensuring that the arc-shaped pressure plate 11 can have a good fixing effect on the steel pipe.

[0027] The working principle of the present utility model is as follows: the worker first starts the second servo motor 13, and the second servo motor 13 drives the threaded rod 14 to rotate. Since the limiting effect of the connecting rod 17 and the through-notch 16 acts on the nut 15, the nut 15 can move along the length direction of the threaded rod 14, and drive the three baffles 5 to move at the same time, adjust the baffle 5 to the required position, and then place the material receiving rack for the cut steel pipe on the side of the connecting shaft 2, and then place the steel pipe to be cut on the first arc-shaped bracket 3, and make one end of the steel pipe rest against the surface of the baffle 5, start the second electric push rod 20, and the telescopic end of the second electric push rod 20 drives the U-shaped plate 21 to descend, thereby driving the two arc pressure plates 11 The surfaces of the steel pipe on both sides of the cutting position are pressed tightly to fix it, and then the first electric push rod 8 and the rotary motor 9 are started. The telescopic end of the first electric push rod 8 drives the rotary motor 9 and the cutting disc 10 to descend, and the rotary motor 9 drives the cutting disc 10 to rotate rapidly to cut the steel pipe. After the cutting is completed, the rotary motor 9 and the cutting disc 10 are driven to rise by the first electric push rod 8, and the two arc-shaped pressure plates 11 are driven to rise by the second electric push rod 20. Then the first servo motor 4 is started to drive the connecting shaft 2 to rotate 120 degrees, so that the cut steel pipe inside the first arc bracket 3 is flipped to one side and falls on the material receiving rack, thereby completing the purpose of automatic material retrieval of the steel pipe, reducing the workload of workers and improving production efficiency.
