Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting shaping, and in particular to a welding pipe fitting shaping device. Background Technology

[0002] Because LNG carrier cargo handling systems need to handle cryogenic natural gas at -163°C, their piping systems are made of 316L cryogenic stainless steel. The connection of the cryogenic pipes is generally done by welding. For large-diameter pipes, butt welding is very difficult. In actual construction, the pipe ends of the two pipes may not align properly due to manufacturing, transportation, thermal deformation and other factors. Therefore, it is necessary to reshape the pipe ends.

[0003] Patent publication number CN219817567U discloses a pipe end shaping fixture, including a clamp, the outer side of which is connected to symmetrically distributed connecting plates. The outer side of the connecting plates has threaded holes perpendicular to the outer circumference of the pipe, and shaping screws are installed within the threaded holes. Compared with existing technologies, this fixture can effectively shape the pipe end, improve construction efficiency, reduce material waste, and ensure the welding quality of butt welding of low-temperature pipes. However, during shaping, the fixture requires workers to tighten each shaping screw individually. Since there are several shaping screws, a significant amount of time is spent on pipe shaping, reducing the fixture's overall shaping efficiency. Utility Model Content

[0004] To address the issue mentioned above where existing fittings require workers to individually tighten each shaping screw during the shaping process, resulting in a significant time commitment for workers and reduced shaping efficiency, this invention provides a welding pipe fitting shaping device.

[0005] This utility model provides a welding pipe fitting shaping device, which adopts the following technical solution:

[0006] A welding pipe shaping device includes a base, and a translation mechanism is provided inside the base. A first bearing plate and a second bearing plate are respectively installed at both ends of the top of the translation mechanism. A clamping assembly is provided on the top side of the first bearing plate and the second bearing plate near the center of the base. A first pipe is placed inside the clamping assembly at the left end, and a second pipe is placed inside the clamping assembly at the right end. A shaping assembly is provided on the right side of the clamping assembly at the left end.

[0007] The shaping assembly includes several connecting plates, which are connected to the right side of the clamping assembly on the left end. Each of the connecting plates is equipped with an electric push rod on the side near the center of the first pipe, and a shaping block is installed at the output end of the electric push rod.

[0008] By adopting the above technical solution, the first pipe is clamped and fixed by the first bearing plate and the clamping assembly at the left end, and the second pipe is clamped and fixed by the second bearing plate and the clamping assembly at the right end. At the same time, the translation mechanism drives the first bearing plate and the second bearing plate to move and approach each other, thereby driving the first pipe and the second pipe to move and approach each other, so that the pipe openings of the first pipe and the second pipe are aligned. Several electric push rods are controlled to extend simultaneously, and the extension of the electric push rods drives the shaping blocks to move towards the direction of the second pipe. By applying different pressures to the pipe opening of the second pipe by several shaping blocks, the pipe opening of the second pipe can be shaped until it matches the pipe opening of the first pipe.

[0009] Optionally, the translation mechanism includes a bidirectional threaded rod, which is connected to the inside of the base via bearings. A servo motor for driving the bidirectional threaded rod to rotate is installed on the right side of the base. Movable sleeves are screwed to both ends of the outer side of the bidirectional threaded rod. Support plates are installed on the top of both sets of movable sleeves. The tops of the two sets of support plates are fixedly connected to the bottoms of the first bearing plate and the second bearing plate, respectively.

[0010] By adopting the above technical solution, when the servo motor is working, it drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the two sets of movable sleeves to move and approach each other. In turn, the first and second pipes can be moved and approached through the first and second bearing plates, so that the pipe openings of the first and second pipes can be aligned.

[0011] Optionally, a limiting mechanism is provided between the movable sleeve and the base. The limiting mechanism includes two sets of movable blocks, which are respectively installed at the bottom of the two sets of movable sleeves. Movable grooves are provided at both ends of the inner bottom wall of the base, and the movable blocks are slidably connected to the movable grooves.

[0012] By adopting the above technical solution, when the movable sleeve moves, it drives the movable block to slide inside the movable groove, thereby limiting the movable sleeve and preventing the movable sleeve from rotating.

[0013] Optionally, a support base is installed at the top end of both the first and second support plates away from the clamping assembly.

[0014] By adopting the above technical solution, the first and second pipes can be supported by the support base, making the first and second pipes move more smoothly.

[0015] Optionally, the clamping assembly includes two sets of second clamping seats, which are respectively installed on the top of the first bearing plate and the second bearing plate. Each of the second clamping seats has a first clamping seat installed on its top. The first and second clamping seats are provided with fixing members inside, and the connection between the first and second clamping seats is provided with connecting members.

[0016] By adopting the above technical solution, the first clamping seat and the second clamping seat are connected by a connector, and the first clamping seat and the second clamping seat clamp the ends of the first pipe and the second pipe that are close to each other.

[0017] Optionally, the fixing component includes a one-way threaded rod, which is screwed to the top of the first clamping seat. A turntable is installed on the top of the one-way threaded rod, and a movable seat is connected to the bottom of the one-way threaded rod via a bearing. A movable rod is connected between the movable seat and the first clamping seat. A support column is installed on the inner bottom wall of the second clamping seat, and a fixed seat is installed on the top of the support column.

[0018] By adopting the above technical solution, the rotation of the turntable drives the one-way threaded rod to rotate. Under the limiting action of the movable rod, the rotation of the one-way threaded rod drives the movable seat to move downward, thereby placing the first pipe and the second pipe between the movable seat and the fixed seat, thus making the first pipe and the second pipe more securely fixed.

[0019] Optionally, the connector includes a locking block, which is installed at both ends of the bottom of the first clamping seat, and the top of the second clamping seat is provided with a locking groove that engages with the locking block at both ends.

[0020] By adopting the above technical solution, the card block is snapped into the inside of the card slot, thereby enabling the first clamping seat to be installed on top of the second clamping seat.

[0021] Optionally, a T-shaped fixing rod is connected to the outer side of the second clamping seat, a positioning spring is sleeved on the outer side of the T-shaped fixing rod, an mounting plate is installed between the T-shaped fixing rods, a pull rod is connected to the side of the mounting plate away from the second clamping seat, a limit rod is connected to the side of the mounting plate away from the pull rod, and a limit groove is opened on the outer side of the locking block to engage with the limit rod.

[0022] By adopting the above technical solution, when the card block is engaged inside the card slot, the mounting plate is reset under the elastic force of the positioning spring, which in turn drives the limiting rod to engage inside the limiting groove. The limiting rod can then lock and fix the card block, making the connection between the card slot and the card block more secure.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] By coordinating the connecting plate, electric actuator, and shaping block, the electric actuator extends simultaneously to move the shaping block toward the opening of the second pipe, thereby effectively and quickly shaping the pipe opening and improving the shaping efficiency of the device.

[0025] By cooperating with the support base, the first bearing plate, the second bearing plate, the first clamping base, the connector, and the second clamping base, the first and second pipes of different specifications can be clamped and fixed. The fixing components make the clamping of the first and second pipes more secure, so that the pipes do not need to be supported by external force during the shaping process, thus further improving the shaping effect of the device.

[0033] The following is combined with Figure 1-5 The present invention will be described in further detail below.

[0034] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 This utility model provides an embodiment of a welded pipe shaping device, including a base 4. A translation mechanism 6 is provided inside the base 4. A first bearing plate 3 and a second bearing plate 7 are respectively installed at the two ends of the top of the translation mechanism 6. A clamping component 9 is provided on the side of the top of the first bearing plate 3 and the second bearing plate 7 near the center of the base 4. A first pipe 1 is placed inside the left clamping component 9, and a second pipe 8 is placed inside the right clamping component 9. The translation mechanism 6 includes a bidirectional threaded rod 603, which is rotatably connected to the inside of the base 4 through a bearing. A servo motor 601 for driving the bidirectional threaded rod 603 to rotate is installed on the right side of the base 4. Movable sleeves 602 are screwed to both ends of the outer side of the bidirectional threaded rod 603. Support plates 604 are fixedly installed on the top of the two sets of movable sleeves 602. The tops of the two sets of support plates 604 are fixedly connected to the bottoms of the first bearing plate 3 and the second bearing plate 7, respectively. When the servo motor 601 is working, it drives the bidirectional threaded rod 603 to rotate. The rotation of the bidirectional threaded rod 603 drives the two sets of movable sleeves 602 to move and approach each other. In turn, the first bearing plate 3 and the second bearing plate 7 can drive the first pipe 1 and the second pipe 8 to move and approach each other, so as to make the pipe openings of the first pipe 1 and the second pipe 8 aligned.

[0035] Please refer to the attached diagram in the instruction manual. Figure 1 A limiting mechanism 5 is provided between the movable sleeve 602 and the base 4. The limiting mechanism 5 includes two sets of movable blocks 501, which are fixedly installed on the bottom of the two sets of movable sleeves 602. Movable grooves 502 are provided at both ends of the inner bottom wall of the base 4, and the movable blocks 501 are slidably connected to the movable grooves 502. When the movable sleeve 602 moves, it causes the movable blocks 501 to slide inside the movable grooves 502, thereby limiting the movement of the movable sleeve 602 and preventing it from rotating.

[0036] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2 Each of the top ends of the first bearing plate 3 and the second bearing plate 7, away from the clamping assembly 9, is equipped with a support base 2. This allows the support base 2 to support the first pipe 1 and the second pipe 8, making their movement more stable.

[0037] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 2The clamping assembly 9 includes two sets of second clamping seats 904, which are respectively installed on the top of the first support plate 3 and the second support plate 7. A first clamping seat 902 is installed on the top of each second clamping seat 904. A fixing member 901 is provided inside the first clamping seat 902 and the second clamping seat 904. A connecting member 903 is provided at the connection point of the first clamping seat 902 and the second clamping seat 904. The first clamping seat 902 and the second clamping seat 904 are connected by the connecting member 903, and the first clamping seat 902 and the second clamping seat 904 clamp the adjacent ends of the first pipe 1 and the second pipe 8.

[0038] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 The fixing component 901 includes a one-way threaded rod 9012, which is screwed to the top of the first clamping seat 902. A turntable 9011 is mounted on the top of the one-way threaded rod 9012, and a movable seat 9014 is rotatably connected to the bottom of the one-way threaded rod 9012 via a bearing. A movable rod 9013 is vertically connected between the movable seat 9014 and the first clamping seat 902. A support column 9016 is mounted on the inner bottom wall of the second clamping seat 904, and a fixed seat 9015 is mounted on the top of the support column 9016. The rotation of the turntable 9011 drives the one-way threaded rod 9012 to rotate. Under the limiting action of the movable rod 9013, the rotation of the one-way threaded rod 9012 drives the movable seat 9014 to move downward, thereby placing the first pipe 1 and the second pipe 8 between the movable seat 9014 and the fixed seat 9015, thus fixing the first pipe 1 and the second pipe 8 more securely.

[0039] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 4 The connector 903 includes a locking block 9032, which is fixedly installed at both ends of the bottom of the first clamping seat 902. Both ends of the top of the second clamping seat 904 are provided with locking grooves 9031 that engage with the locking block 9032. By locking the locking block 9032 into the grooves 9031, the first clamping seat 902 can be installed on the top of the second clamping seat 904.

[0040] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 4A T-shaped fixing rod 9038 is fixedly connected to the outer side of the second clamping seat 904. A positioning spring 9036 is sleeved on the outer side of the T-shaped fixing rod 9038. An mounting plate 9035 is slidably installed between the T-shaped fixing rods 9038. A pull rod 9037 is connected to the side of the mounting plate 9035 opposite to the second clamping seat 904. A limit rod 9034 is connected to the side of the mounting plate 9035 opposite to the pull rod 9037. A limit groove 9033 is opened on the outer side of the locking block 9032 to engage with the limit rod 9034. When the locking block 9032 is engaged in the slot 9031, the mounting plate 9035 is reset under the elastic force of the positioning spring 9036, which in turn drives the limit rod 9034 to engage in the slot 9033. The limit rod 9034 locks the locking block 9032 in place, making the connection between the slot 9031 and the locking block 9032 more secure.

[0041] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 5 A shaping component 10 is provided on the right side of the left clamping component 9. The shaping component 10 includes several connecting plates 1001. The several connecting plates 1001 are fixedly connected to the right side of the left clamping component 9. An electric push rod 1003 is installed on the side of the several connecting plates 1001 near the center of the first pipe 1. A shaping block 1002 is installed on the output end of the electric push rod 1003.

[0042] Working principle: In use, place the first pipe 1 on top of the left end support 2 and the second clamping seat 904, and place the second pipe 8 on top of the right end support 2 and the second clamping seat 904. Then pull the lever 9037 outward. The lever 9037 drives the mounting plate 9035 to move and compresses the positioning spring 9036. At the same time, the mounting plate 9035 moves and drives the limiting rod 9034 to move. At this time, the locking block 9032 is inserted into the slot 9031. Then release the lever 9037. Under the elastic force of the positioning spring 9036, the mounting plate 9035 returns to its original position and drives the limiting rod 9034 to lock into the limiting groove 9033, thereby locking the locking block 9032 and fixing the first clamping seat 902 and the second clamping seat 904 together.

[0043] According to the specifications of the first pipe 1 and the second pipe 8, the operator rotates the turntable 9011. The rotation of the turntable 9011 drives the one-way threaded rod 9012 to rotate. Since the one-way threaded rod 9012 is rotatably connected to the movable seat 9014, and under the limiting action of the movable rod 9013, the rotation of the one-way threaded rod 9012 drives the movable seat 9014 to move downward, thereby pressing and fixing the first pipe 1 and the second pipe 8.

[0044] Next, the servo motor 601 is turned on. When the servo motor 601 is working, it drives the bidirectional threaded rod 603 to rotate. Under the sliding cooperation of the movable block 501 and the movable groove 502, the bidirectional threaded rod 603 rotates and drives the two sets of movable sleeves 602 to move and approach each other, thereby driving the first bearing plate 3 and the second bearing plate 7 to move and approach each other until the pipe opening of the second pipe 8 is located between the shaping blocks 1002, so that the pipe openings of the first pipe 1 and the second pipe 8 are aligned.

[0045] Finally, several electric actuators 1003 are extended simultaneously. The extension of the electric actuators 1003 drives the shaping block 1002 to move toward the second pipe 8. By applying different pressures to the pipe opening of the second pipe 8 through several shaping blocks 1002, the pipe opening of the second pipe 8 can be shaped until it matches the pipe opening of the first pipe 1.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
