Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe cutting devices, specifically to a track-type fully automatic CNC seamless steel pipe sawing machine. Background Technology

[0002] Seamless steel pipes are metal pipes formed in one go from round steel billets through hot rolling or cold drawing processes. Their seamless structure makes them superior to welded pipes in terms of pressure resistance. They are characterized by uniform structure, high strength, and corrosion resistance. Their mechanical properties can be adjusted through heat treatment. They are widely used in industrial fields such as high-pressure boilers, petroleum cracking, and hydraulic systems. Their outer diameter and wall thickness tolerances are precise, making them suitable for harsh working conditions such as fluid transportation and structural support. They are an indispensable basic material in energy equipment and precision manufacturing.

[0003] In existing technologies, operators often use CNC sawing machines to quickly cut seamless steel pipes. However, existing CNC sawing machines typically cut seamless steel pipes from top to bottom. When cutting the lower half of the pipe, the connection between the parts of the pipe on both sides of the cut gradually decreases. This causes the cut portion of the pipe to bend directly at the bottom, greatly reducing the cutting quality of the steel pipe. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a track-type fully automatic CNC seamless steel pipe saw, which solves the technical problem of poor cutting quality in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a track-type fully automatic CNC seamless steel pipe saw, including a table, a placement block fixedly connected to the upper surface of the table, a first motor fixedly installed on the right side of the lower surface of the table, a round shaft fixedly sleeved at the other end of the output shaft of the first motor, a drive rod fixedly sleeved on the outer surface of the round shaft, driven rods hinged to both ends of the drive rod, an L-shaped frame hinged to the other end of the driven rod, a mounting plate fixedly connected to the other end of the L-shaped frame above the table, a second motor fixedly installed on both the upper and lower sides of the right surface of the mounting plate, a rotating shaft fixedly sleeved at the other end of the output shaft of the second motor, and a drive wheel fixedly sleeved on the right side of the outer surface of the rotating shaft penetrating the mounting plate and extending to the left side of the mounting plate.

[0006] For example, two limiting blocks are fixedly connected to the front and rear sides of the top right surface of the placement block. The inner surfaces of the two limiting blocks are respectively movably connected to the outer surfaces of the two L-shaped frames. A connecting plate is fixedly connected to the right end of the upper surface of the table.

[0007] For example, a support column is fixedly connected to the lower surface of the tabletop, a top rod is fixedly connected to the left side of the upper surface of the placement block, a fixing plate is fixedly connected to the top of the top rod, and the right end of the fixing plate is fixedly connected to the left surface of the sleeve plate.

[0008] For example, a toothed plate is movably connected to the upper surface of the fixed plate, and a feeding rod is fixedly connected to the left side of the lower surface of the toothed plate. The outer surface of the feeding rod is movably connected to the inner surface of the fixed plate.

[0009] For example, a servo motor is fixedly mounted on the upper surface of the socket plate, a drive shaft is fixedly sleeved at the other end of the output shaft of the servo motor, a gear is fixedly sleeved on the outer surface of the drive shaft, the outer surface of the gear is meshed with the outer surface of the gear plate, and an L-shaped block is fixedly connected to the rear side of the upper surface of the socket plate, the outer surface of the L-shaped block is movably connected to the outer surface of the gear plate.

[0010] For example, mounting blocks are fixedly connected to the upper and lower sides of the front and rear ends of the right surface of the socket plate. A first drive motor is fixedly installed on the front side of the upper surface of the mounting block. A lead screw is fixedly sleeved on the other end of the output shaft of the first drive motor. The bottom end of the lead screw passes through the mounting block and extends to the bottom of the mounting block.

[0011] For example, the outer surface of the lead screw is threaded with a movable plate located between the mounting blocks, and the movable plate is rectangular in shape.

[0012] For example, a limiting rod is fixedly connected to the rear side of the upper surface of the mounting block. The bottom end of the limiting rod passes through the mounting block and the moving plate in sequence and extends to the lower surface of the mounting block. The outer surface of the limiting rod and the inner surface of the moving plate are movably connected.

[0013] For example, a second drive motor is fixedly installed on the inner surface of the moving plate, and a rotating shaft is fixedly sleeved on the other end of the output shaft of the second drive motor. A saw blade is fixedly installed on the outer surface of the rotating shaft.

[0014] For example, the number of placement blocks is two, and the outer surfaces of the two placement blocks are smooth.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, by setting up an active rod, a driven rod, an L-shaped frame, a mounting plate, and driving wheels, when the No. 1 motor runs, the round shaft, the active rod, and the driven rod will start to rotate. As the driven rod rotates, the two L-shaped frames will move towards each other, eventually causing the four driving wheels to contact the outer surface of the steel pipe. At this time, the operation of the No. 2 motor will cause the rotating shaft and driving wheels to rotate. The rotation of the driving wheels will cause the seamless steel pipe to start rotating as well. This allows the uncut part of the seamless steel pipe to move from the bottom to the side closer to the saw blade during the cutting process, thereby avoiding the steel pipe from bending and causing the cut surface to be uneven.

[0016] 2. In this utility model, by setting a fixed plate, a toothed plate, a feeding rod, a gear, and an L-shaped block, when the servo motor is running, the drive shaft and the gear will start to rotate. The rotation of the gear will drive the toothed plate, thereby causing the toothed plate and the feeding rod to move to the right. During this process, the feeding rod will drive the steel pipe, thereby causing the steel pipe to move to the right, thus realizing the automatic feeding function of the steel pipe.

[0025] like Figures 1-6 As shown, this invention illustrates a track-type fully automatic CNC seamless steel pipe sawing machine according to one embodiment of the present invention. It includes a table 1, with a placement block 2 fixedly connected to the upper surface of the table 1. A first motor 3 is fixedly installed on the right side of the lower surface of the table 1. A round shaft 4 is fixedly sleeved at the other end of the output shaft of the first motor 3. A drive rod 5 is fixedly sleeved on the outer surface of the round shaft 4. Both ends of the drive rod 5 are hinged to driven rods 6. An L-shaped frame 7 is hinged to the other end of the driven rod 6. A mounting plate 8 located above the table 1 is fixedly connected to the other end of the L-shaped frame 7. A second motor 9 is fixedly installed on both the upper and lower sides of the right surface of the mounting plate 8. A rotating shaft 10 is fixedly sleeved at the other end of the output shaft of the second motor 9. The left end of the outer surface of the rotating shaft 10 passes through the mounting plate 8 and extends to the left side of the mounting plate 8, where a drive wheel 11 located on the right side of the placement block 2 is fixedly sleeved.

[0026] There are four drive wheels 11, all of which are made of hard rubber. The outer surfaces of the four drive wheels 11 are roughened. When the four drive wheels 11 clamp the outer surface of the steel pipe and rotate, the steel pipe will rotate under the drive of the drive wheels 11.

[0027] In some examples, such as Figure 6 As shown, two limit blocks 13 are fixedly connected to the front and rear sides of the top right surface of the placement block 2. The inner surfaces of the two limit blocks 13 are movably connected to the outer surfaces of the two L-shaped frames 7 respectively. A sleeve plate 12 is fixedly connected to the right end of the upper surface of the table 1.

[0028] The inner surface of the limiting block 13 is smooth, thereby reducing the frictional loss that may occur when the L-shaped frame 7 moves inside the limiting block 13.

[0029] In some examples, such as Figure 1 As shown, a support column 14 is fixedly connected to the lower surface of the tabletop 1, a top rod 15 is fixedly connected to the left side of the upper surface of the placement block 2, a fixing plate 16 is fixedly connected to the top of the top rod 15, and the right end of the fixing plate 16 is fixedly connected to the left surface of the sleeve plate 12.

[0030] The design of the top rod 15 serves to support the fixing plate 16.

[0031] In some examples, such as Figure 3 As shown, a toothed plate 17 is movably connected to the upper surface of the fixed plate 16, and a feeding rod 18 is fixedly connected to the left side of the lower surface of the toothed plate 17. The outer surface of the feeding rod 18 is movably connected to the inner surface of the fixed plate 16.

[0032] The design of the inner surface of the fixing plate 16 restricts the movement direction of the feeding rod 18.

[0033] In some examples, such as Figure 3 As shown, a servo motor 19 is fixedly mounted on the upper surface of the socket plate 12. A drive shaft 20 is fixedly sleeved at the other end of the output shaft of the servo motor 19. A gear 21 is fixedly sleeved on the outer surface of the drive shaft 20. The outer surface of the gear 21 meshes with the outer surface of the gear plate 17. An L-shaped block 30 is fixedly connected to the rear side of the upper surface of the socket plate 12. The outer surface of the L-shaped block 30 is movably connected to the outer surface of the gear plate 17.

[0034] The design of the L-shaped block 30 serves to protect the engagement of the toothed plate 17 and restrict its movement direction.

[0035] In some examples, such as Figure 4 As shown, mounting blocks 22 are fixedly connected to the upper and lower sides of the front and rear ends of the right surface of the socket plate 12. A first drive motor 23 is fixedly installed on the front side of the upper surface of the mounting block 22. A lead screw 24 is fixedly sleeved on the other end of the output shaft of the first drive motor 23. The bottom end of the lead screw 24 passes through the mounting block 22 and extends to the bottom of the mounting block 22.

[0036] The first drive motor 23 is a self-locking motor. When the first drive motor 23 is not started, the lead screw 24 will be locked and cannot rotate.

[0037] In some examples, such as Figure 4 As shown, a movable plate 25 located between mounting blocks 22 is threaded onto the outer surface of the lead screw 24. The movable plate 25 is rectangular in shape.

[0038] The inner surface of the screw thread 24 is smooth, which ensures smooth transmission of the screw thread 24.

[0039] In some examples, such as Figure 4 As shown, a limiting rod 26 is fixedly connected to the rear side of the upper surface of the mounting block 22. The bottom end of the limiting rod 26 passes through the mounting block 22 and the moving plate 25 in sequence and extends to the lower surface of the mounting block 22. The outer surface of the limiting rod 26 and the inner surface of the moving plate 25 are movably connected.

[0040] The design of the limit rod 26 serves to restrict the movement direction of the movable plate 25.

[0041] In some examples, such as Figure 5 As shown, a second drive motor 27 is fixedly installed on the inner surface of the moving plate 25, and a rotating shaft 28 is fixedly sleeved on the other end of the output shaft of the second drive motor 27. A saw blade 29 is fixedly installed on the outer surface of the rotating shaft 28.

[0042] The saw blade 29 can be removed from the outer surface of the rotating shaft 28, thereby preventing damage to the saw blade 29.

[0043] In some examples, such as Figure 1 As shown, there are two placement blocks 2, and the outer surfaces of the two placement blocks 2 are smooth.

[0044] The design of two placement blocks 2 reduces the contact area between the seamless steel pipe and the placement blocks 2, thereby reducing the frictional resistance experienced by the seamless steel pipe during rotation.

[0045] Working principle and usage process of this utility model: First, the operator places the seamless steel pipe between the two placement blocks 2. Then, the operator starts the servo motor 19. As the servo motor 19 runs, the drive shaft 20 and gear 21 will start to rotate. At this time, the toothed plate 17 and the feeding rod 18 will start to move to the right under the drive of the gear 21. The movement of the feeding rod 18 will drive the seamless steel pipe, thus causing the seamless steel pipe to start to move to the right until the distance between the right end of the seamless steel pipe and the right surface of the socket plate 12 meets the operator's cutting needs.

[0046] At this point, the operator first starts motor 3. As motor 3 runs, the circular shaft 4, the driving rod 5, and the driven rod 6 begin to rotate, causing the two L-shaped frames 7 to move towards each other until the four drive wheels 11 clamp the steel pipe. Then, the operator starts motor 9, drive motor 23, and drive motor 27. The operation of motor 9 causes the rotating shaft 10, drive wheels 11, and seamless steel pipe to rotate during the cutting process. The operation of drive motor 23 causes the lead screw 24 to rotate, and the moving plate 25 moves downward under the drive of the lead screw 24. The operation of drive motor 27 causes the rotating shaft 28 and the saw blade 29 to rotate. Finally, under the combined action of drive wheels 11, moving plate 25, and saw blade 29, the seamless steel pipe is cut off smoothly.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
