Description

Technical Field

[0001] The invention relates to the technical field of seamless pipe processing, in particular to a seamless pipe splitting and groove opening tool. Background Art

[0002] A seamless pipe is a long strip of steel with a hollow cross-section and no seams around it. During the actual installation process of the seamless pipe, the seamless pipe needs to be cut open according to different usage environments.

[0003] For example, Chinese invention CN116551117A discloses a thickened seamless pipe cutting and groove opening tool. The opening tool is composed of a moving group, an equipment plate, an adjustment group and a track structure. The moving motor drives the driving wheel, and the driven wheel assists the equipment to move. The support column controls its forward and backward movement by rotating the transverse control bolt, and the longitudinal control bolt inside the support column regulates the argon arc welding. The boom group and the hanging wire group have a stabilizing effect. The cable group is responsible for the lifting and lowering of the pipe, and the flipping group is used to flip the pipe.

[0004] However, there are still several problems in the actual use of the above-mentioned reference documents:

[0005] 1. In the process of cutting the seamless pipe, the seamless pipe must be lifted up by the cable group and the hanging wire group before the cutting angle of the seamless pipe can be adjusted. The operation is cumbersome, and only 180 degrees of horizontal adjustment can be performed. It is impossible to achieve multi-angle cutting adjustment during the cutting process of the seamless pipe, and the practicality is low.

[0006] 2. When cutting the seamless pipe, the seamless pipe cannot be fixed well. During the cutting process, the seamless pipe is prone to deviation and will deviate from the original groove position, increasing the defective rate of the seamless pipe after cutting. Summary of the invention

[0016] Optionally, a second groove is provided on the surface of the flip member, and a rotating rod is connected to the inner wall of the second groove for fixed axis rotation. A friction tube is fixedly connected to the surface of the rotating rod, and a rubber layer is provided on the outer surface of the friction tube.

[0022] 1. The present invention starts motor 3 to drive the threaded rod to rotate, driving the two arc-shaped clamping plates to move in the direction of approaching each other. When the two arc-shaped clamping plates are in contact with the surface of the seamless pipe, as the connecting block continues to move, the spring will be compressed. Under the action of the elastic potential energy of the spring, the seamless pipe can be fixed once by the two arc-shaped clamping plates. As the connecting block moves, under the action of the hinged plate, the arc-shaped clamping plate 2 will deflect in the direction of approaching the seamless pipe with the hinged rod as the axis. Under the action of the arc-shaped clamping plate 2, the seamless pipe can be fixed twice from another angle. The two fixations have good fixing effects and effectively solve the problem that when the seamless pipe is cut, the fixing effect of the seamless pipe on the tooling is poor, which easily causes the seamless pipe to deviate during cutting and deviate from the original groove position.

[0023] Second, the present invention starts the motor three to drive the threaded rod to rotate in the opposite direction, and drives the two arc-shaped clamping plates to move away from each other to release the fixation of the seamless pipe. Under the linkage cooperation of multiple structures, the gear two drives the rotating rod and the friction tube to rotate, and cooperates with the rubber layer on the outer surface of the friction tube. Under the action of friction force, the seamless pipe is rotated in the flip part, so that the second cutting position of the seamless pipe can be adjusted;

[0024] By observing that the second marker is pointing to a different first marker, the deflection angle of the seamless pipe can be intuitively obtained. The adjustment of the cut angle of the seamless pipe can be completed on the flipping piece without lifting the entire seamless pipe, so as to adapt to different connection cuts. It has stronger applicability and is worthy of promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figures 1 to 9The present invention provides a seamless pipe splitting and groove opening tool, comprising a bottom plate 1 and a seamless pipe 10, a fixing column 17 is fixedly connected to the upper surface of the bottom plate 1, a flip member 23 is fixedly installed above the fixing column 17, a limited position frame 7 is fixedly installed on the upper surface of the bottom plate 1, a support plate 18 is fixedly connected to the surface of the fixing column 17, a driver 2 is fixedly installed above the support plate 18, an electric guide rail 4 is arranged above the driver 2, a moving plate 11 is arranged above the electric guide rail 4, a motor 12 is arranged on the upper surface of the moving plate 11, an output shaft of the motor 12 is fixedly connected to a rotating plate 13, a motor 2 14 is installed on the surface of the rotating plate 13, and a cutting disc 16 is threadedly connected to the output shaft of the motor 2 14;

[0037] A fixing component is arranged inside the limiting frame 7 , and an adjusting component is arranged inside the flipping member 23 .

[0038] The fixing component includes a motor 3 9 arranged on the upper surface of the limit frame 7, the output shaft of the motor 3 9 is fixedly connected with a threaded rod 35, the surface of the threaded rod 35 is provided with two sections of oppositely arranged threaded grooves, the surface of the threaded rod 35 is threadedly connected with two symmetrically arranged moving blocks 41, the ends of the moving blocks 41 are fixedly connected with connecting blocks 42, the surface of the connecting blocks 42 is provided with a telescopic rod, the end of the telescopic rod is fixedly connected with an arc-shaped clamping plate 5, and a spring 45 is commonly provided between the arc-shaped clamping plate 5 and the connecting blocks 42.

[0039] The fixing member also includes a notch 44 formed on the inner wall of the arc-shaped clamping plate 5, the inner wall of the notch 44 is connected to a hinge rod for fixed axis rotation, the notch 44 is hinged to the arc-shaped clamping plate 6 through the hinge rod, and a hinge plate 43 is hinged between the arc-shaped clamping plate 6 and the connecting block 42;

[0040] There are two groups of arc-shaped clamping plates 2 6 and they are symmetrically distributed around the center of arc-shaped clamping plate 1 5 .

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the motor 12 is turned on to drive the rotating plate 13 to rotate 90 degrees to a position where the seamless pipe 10 is not blocked. At this time, the two arc-shaped clamping plates 15 on a set of limit frames 7 have not moved to the closest position. The seamless pipe 10 to be processed is placed on the two flipping members 23 through the middle position of the two arc-shaped clamping plates 15. After the seamless pipe 10 is placed, Figure 6As shown, the motor 39 is turned on to drive the threaded rod 35 to rotate. Since the surface of the threaded rod 35 is provided with two oppositely arranged threaded grooves, and the two threaded grooves are respectively connected to two symmetrically arranged moving blocks 41, as the threaded rod 35 rotates, the two moving blocks 41 are driven to move in the direction of approaching each other, so that the two connecting blocks 42 can drive the two arc-shaped clamping plates 5 to move in the direction of approaching each other, until the two arc-shaped clamping plates 5 are both in contact with the surface of the seamless tube 10, as the two connecting blocks 42 continue to move, the two springs 45 are compressed. At this time, under the action of the elastic potential energy of the spring 45, the two arc-shaped clamping plates 5 can complete the one-time fixation of the seamless tube 10. The setting of the telescopic rod between the connecting block 42 and the arc-shaped clamping plate 5 can prevent the spring 45 from tilting when being compressed, thereby extending the service life of the spring 45.

[0042] It is worth noting that when the two arc-shaped clamps 5 are in contact with the surface of the seamless tube 10, as the connecting block 42 continues to move, under the hinged action of the hinged plate 43, the arc-shaped clamp 2 6 will also deflect in the direction close to the seamless tube 10 with the hinge rod as the axis. At this time, under the action of the arc-shaped clamp 2 6, the seamless tube 10 can be fixed for the second time from another angle. The two fixations have a good fixing effect, which effectively solves the problem that when the seamless tube 10 is cut, the fixing effect of the seamless tube 10 on the tooling is poor, resulting in the seamless tube being offset during cutting and deviating from the original groove position.

[0043] After the seamless pipe 10 is fixed, the motor 12 is rotated in the reverse direction to drive the rotating plate 13 to rotate in the reverse direction 90 degrees until it reaches the side of the seamless pipe 10. Then, the built-in power supply of the driver 2 and the motor 2 14 are turned on, so that the cutting disc 16 can slide horizontally along the electrical guide rail 4 while rotating at high speed, thereby completing the cutting and opening of the first incision of the seamless pipe 10. The driver 2 drives the components in the electrical guide rail 4 to move horizontally along the electrical guide rail 4. This is a relatively mature prior art in the field of linear guides and will not be described in detail here.

[0044] Embodiment 2, based on the above embodiment:

[0045] Further, the adjustment component in the first embodiment is disclosed as follows: the adjustment component includes a second moving block 36 threadedly connected to the surface of the threaded rod 35, a connecting rod is fixedly connected to the surface of the second moving block 36, a rectangular notch is provided on the surface of the limit frame 7 for the connecting rod to extend and slide, and a rack row 28 is fixedly installed at the end of the connecting rod;

[0046] A housing 24 is fixedly mounted on the surface of the flip member 23 , a rotating shaft 27 is fixedly rotatably connected to the inner wall of the housing 24 , and a gear 26 meshing with a rack row 28 is fixedly connected to the surface of the rotating shaft 27 .

[0047] A second slot 32 is provided on the surface of the flip member 23, and the inner wall of the second slot 32 is connected to the rotating rod 21 in a fixed axis rotation manner. The surface of the rotating rod 21 is fixedly connected to the friction tube 20, and the outer surface of the friction tube 20 is provided with a rubber layer. A one-way bearing 34 is provided at the end of the rotating rod 21, and the rotating rod 21 is fixedly connected to the second rotating shaft 30 through the one-way bearing 34. The surface of the second rotating shaft 30 is fixedly connected to the second gear 29 meshing with the first gear 26.

[0048] A plurality of index 1s 31 distributed in a circumferential array are fixedly connected to the surface of the gear 1 26 , and a index 2 25 is fixedly connected to the surface of the housing 24 .

[0049] When using: Figure 6 , Figure 7 and Figure 8 As shown, since the threaded groove at the position of the moving block 2 36 is opened in the same direction as the threaded groove at the position of the moving block 1 41 above, that is, when the motor 3 9 is turned on, as the threaded rod 35 rotates, when the upper moving block 1 41 drives the upper arc clamping plate 1 5 to descend to clamp and fix the seamless pipe 10, the moving block 2 36 will also move downward synchronously. As the moving block 2 36 moves downward, the rack row 28 will move downward and drive the gear 1 26 to rotate counterclockwise. At this time, the counterclockwise rotation of the gear 1 26 will drive the gear 2 29 to rotate clockwise. Under the action of the one-way bearing 34, the clockwise rotation of the gear 2 29 will not cause the rotating rod 21 to rotate.

[0050] When the first slit of the seamless tube 10 is completed, the motor 3 9 is turned on to make the threaded rod 35 rotate in the opposite direction, which will cause the upper moving block 41 to drive the upper arc-shaped clamping plate 5 to move upward to release the clamping and fixing of the seamless tube 10. Similarly, in this process, the moving block 2 36 will also drive the rack row 28 to move upward, so that the gear 1 26 can rotate clockwise, and under the linkage cooperation of multiple structures, the gear 2 29 can rotate counterclockwise, and under the action of the one-way bearing 34, the counterclockwise rotation of the gear 2 29 will drive the rotating rod 21 to rotate counterclockwise, and the counterclockwise rotation of the rotating rod 21 will cause the friction tube 20 to start rotating. At this time, the arc-shaped clamping plate 5 has released the fixation of the seamless tube 10. As the friction tube 20 rotates, the rubber layer on its outer surface cooperates with the friction force, and the seamless tube 10 rotates in the flip member 23, so that the second slit cutting position of the seamless tube can be adjusted.

[0051] It is worth noting that Figure 7As shown, there are 18 marking fingers 31 and they are distributed in a circular array on the gear 26, and each marking finger 31 is provided with a scale. When the gear 26 rotates, multiple marking fingers 31 will start to rotate. By observing the different marking fingers 31 pointed to by the marking finger 25, the deflection angle of the seamless pipe 10 can be intuitively obtained. There is no need to lift the entire seamless pipe 10, that is, the adjustment of the seamless pipe section angle can be completed on the flip piece 23, so as to adapt to different connection sections, and the applicability is stronger.

[0052] Furthermore, a ratchet 33 is fixedly connected to the surface of the rotating rod 21, and a plurality of ratchet teeth distributed in a circumferential array are fixedly connected to the side of the ratchet 33. A limit rod 38 is fixedly connected to the surface of the flip member 23, and a ratchet pawl 37 is fixedly connected to the surface of the limit rod 38 for fixed axis rotation.

[0053] A first connecting post is fixedly connected to the surface of the pawl 37 , a second connecting post 40 is fixedly connected to the surface of the flip member 23 , and a tension spring 39 is disposed between the first connecting post and the second connecting post 40 .

[0054] A second fixing column is fixedly connected to the upper surface of the bottom plate 1 , a driving box 19 is fixedly installed at the end of the second fixing column, and a plurality of driving columns 22 distributed in a linear array are arranged inside the driving box 19 .

[0055] like Figure 8 and Fig. 9 As shown, the setting of the ratchet mechanism on the surface of the rotating rod 21 can ensure that the rotating rod 21 only rotates counterclockwise, thereby avoiding a small deflection of the seamless tube 10 after the second cutting angle of the seamless tube 10 is adjusted, further ensuring the accurate opening of the cutting during the cutting process of the seamless tube 10, and reducing the defective rate of the finished seamless tube 10 after cutting, which is worthy of promotion and use.

[0056] When the two cuts of the seamless pipe 10 are completed, an ideal groove surface can be obtained. By turning on the built-in power supply of the drive box 19, the multiple drive columns 22 are driven to rotate. Similarly, under the action of friction, the cut seamless pipe 10 can be removed.

[0057] Working principle: When the seamless pipe cutting and groove opening tooling is used, the motor 12 is turned on, and the rotating plate 13 is rotated 90 degrees to a position where the seamless pipe 10 is not blocked, and the seamless pipe 10 to be processed is placed on the two flipping pieces 23 through the middle position of the two arc-shaped clamping plates 5. After the seamless pipe 10 is placed, the motor 3 9 is turned on, which will drive the two moving blocks 41 to move in a direction close to each other, so that the two connecting blocks 42 drive the two arc-shaped clamping plates 5 to move in a direction close to each other, until the two arc-shaped clamping plates 5 are both in contact with the surface of the seamless pipe 10. As the connecting block 42 continues to move, the spring 45 is compressed, and under the action of the elastic potential energy of the spring 45, the seamless pipe 10 can be fixed once by the two arc-shaped clamping plates 5.

[0058] When the two arc-shaped clamping plates 1 5 are in contact with the surface of the seamless tube 10, as the connecting block 42 continues to move, the arc-shaped clamping plate 2 6 will deflect in the direction close to the seamless tube 10 with the hinge rod as the axis under the hinged action of the hinged plate 43. Under the action of the arc-shaped clamping plate 2 6, the seamless tube 10 can be fixed for the second time from another angle. The two fixations have a good fixing effect and effectively solve the problem that when the seamless tube is cut, the seamless tube 10 is easily offset and deviates from the original groove position due to the poor fixing effect of the seamless tube 10 on the tooling when the seamless tube is cut.

[0059] After the seamless pipe 10 is fixed, the built-in power supply of the driver 2 and the motor 2 14 are turned on, so that the cutting disc 16 can slide horizontally along the electrical guide rail 4 while rotating at high speed, thereby completing the cutting and opening of the first cut of the seamless pipe 10.

[0060] Under the action of the one-way bearing 34, when the upper moving block 41 drives the upper arc-shaped clamping plate 5 to descend to clamp and fix the seamless pipe 10, the downward movement of the rack row 28 at this time will not cause the gear 29 and the rotating rod 21 to rotate. When the first cut of the seamless pipe 10 is completed, the motor 3 9 is turned on to drive the threaded rod 35 to rotate in the opposite direction, so that the upper moving block 41 drives the upper arc-shaped clamping plate 5 to move upward to release the clamping and fixing of the seamless pipe 10. As the rack row 28 moves upward, under the linkage cooperation of multiple structures, the gear 29 and the rotating rod 21 will rotate. The second 29 drives the rotating rod 21 and the friction tube 20 to rotate, and cooperates with the rubber layer on the outer surface of the friction tube 20. Under the action of friction, the seamless tube 10 will rotate in the flip piece 23, so that the second cutting position of the seamless tube can be adjusted. By observing the different finger one 31 pointed to by the second finger 25, the deflection angle of the seamless tube 10 can be intuitively obtained. There is no need to lift the entire seamless tube 10, that is, the adjustment of the seamless tube cutting angle can be completed on the flip piece 23, so as to adapt to different connection cuttings. It has stronger applicability and is worthy of promotion and use.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
