Description

Technical Field

[0001] The invention relates to the technical field of metal pipe cooling, in particular to a hot expansion cooling mechanism for a metal pipe. Background Art

[0002] Metal pipe fittings are an important part of metal piping systems. They are used to connect, branch or change the direction of pipelines to ensure the continuity and sealing of pipeline systems. They are widely used in various industrial fields, such as petrochemical, natural gas, shipping, electricity, medicine, etc., as well as construction, aviation, electronics, food and other industries.

[0003] For example, a rapid cooling mechanism for hot bulging of metal pipes with publication number CN220942867U, through the arrangement of a cooling rack, a diversion box, an impact nozzle, a supply pipe and an adjusting valve, is conducive to shaking the metal pipes during the spraying of coolant by the impact nozzle during use, and allowing the coolant to enter the interior of the metal pipes, thereby achieving internal cooling of the metal pipes and achieving the purpose of improving the processing quality of the metal pipes.

[0004] When the above device is in use, the metal pipe is hung by the provided hanging rod, so that the contact area between the metal pipe and the hanging rod is very small. When the metal pipe is transferred to the cooling area, the metal pipe is easy to fall off the hanging rod. At the same time, the narrow contact area is easy to cause the contact part of the metal pipe with the hanging rod to deform during transportation, resulting in quality problems of the final metal pipe. At the same time, it is impossible to ensure that the metal pipe can be transported smoothly during the transfer of the metal pipe. During this process, if the metal pipe falls off the hanging rod, the high-temperature metal pipe will also bring a large amount of heat energy to the surrounding area, resulting in the risk of fire in the cooling area. Summary of the invention

DETAILED DESCRIPTION

[0032] 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.

[0033] Example 1

The trapezoidal plate 42 is in a trapezoidal shape with a small top and a large bottom, which is used to facilitate the reset of the semi-ring plate 31 and avoid the jamming. The processing chamber 2 is symmetrically provided with a swing assembly 5, which is used to make the impurity removal plate 34 reciprocate inside the semi-ring plate 31 under the action of the corrugated guide rail 51 when the semi-ring plate 31 is moved by the gravity of the metal pipe. A driving assembly 6 is provided on the operating table 1, and the driving assembly 6 is used to drive the inner support assembly 7 to move, and at the same time, the inner support assembly 7 is opened during the movement to fix and rotate the metal pipe.

[0035] The bearing assembly 3 includes a semi-ring plate 31 movably arranged inside the processing chamber 2, the semi-ring plate 31 is used to support the metal pipe fittings, a clamping plate 32 symmetrically arranged on one side of the semi-ring plate 31, the clamping plate 32 is a clamping plate with a square notch to prevent the slide bar 33 from rotating when moving, a slide bar 33 movably arranged inside the clamping plate 32, the slide bar 33 is a square rod used to cooperate with the clamping plate 32 to prevent the slide bar 33 from driving the dust removal plate 34 to rotate when moving, a dust removal plate 34 arranged on the slide bar 33, and the dust removal plate 34 is slidably connected to the semi-ring plate 31, and the dust removal plate 34 is used to swing back and forth when the metal pipe fittings are moved. The impurities produced by oxidation on the surface of the metal pipe are scraped off to prevent these impurities from sticking to the surface of the metal pipe when the metal pipe is cooled. It also includes a square clamping plate 35 arranged on the side of the slide rod 33 away from the impurity removing plate 34. The square clamping plate 35 is used to engage and slide with the fixing rod 53, and is used to limit the movement of the impurity removing plate 34 through the square clamping plate 35. A circular clamping rod 36 is arranged on one side of the square clamping plate 35. The circular clamping rod 36 is used to engage and slide with the corrugated guide rail 51. A bearing plate 37 is arranged on the semi-ring plate 31. The bearing plate 37 is used to carry the metal pipe. When the bearing plate 37 descends, the lock of the semi-ring plate 31 can be released, so that the semi-ring plate 31 can move along the limiting groove 21.

[0036] A limiting rod 311 is symmetrically arranged on the semi-ring plate 31, and the limiting rod 311 is engaged and slid with the limiting groove 21 to limit the semi-ring plate 31 when it moves. A rotating plate 371 is symmetrically arranged on one side of the supporting plate 37, and the rotating plate 371 is rotatably connected to the trapezoidal plate 42 away from the side of the supporting plate 37. The rotating plate 371 is used to rotatably connect the trapezoidal plate 42 and the supporting plate 37, so that the movement of one of them can push the other to move. A first spring 373 is arranged inside the supporting plate 37, and the first spring 373 is used to push the locking plate 374.

[0037] A locking plate 374 is movably provided inside the supporting plate 37, and the locking plate 374 is in contact with the first spring 373. The locking plate 374 is a cross circular plate, which is used to lock with the notch of the supporting plate 37 to prevent the locking plate 374 from rotating when moving under the thrust of the first spring 373. A locking rod 372 is provided on the side of the locking plate 374 away from the first spring 373, and a matching block 375 is provided on the side of the locking rod 372 away from the locking plate 374. The matching block 375 is used to cooperate with the inner wall of the semi-ring plate 31 to support the semi-ring plate 31, so that the semi-ring plate 31 will not move in the absence of external force.

[0038] During use, when the metal pipe fittings that have been hot expanded fall on the carrying plate 37, the carrying plate 37 will descend under the gravity of the metal pipe fittings. The descent of the carrying plate 37 pulls the trapezoidal plate 42 to move toward the inside of the sealing plate 41 through the rotating plate 371, and the matching block 375 set on one side of the carrying plate 37 falls off through the gap between the semi-annular plate 31 and the dust-removing plate 34, so that the locking state between the semi-annular plate 31 and the carrying plate 37 is released. At the same time, the descending of the trapezoidal plate 42 facilitates the movement of the semi-annular plate 31. During the movement of the semi-annular plate 31, the symmetrical square clamping plates 35 and the circular clamping rods 36 on both sides of the dust-removing plate 34 are used to make the dust-removing plate 34 swing back and forth through the swinging assembly 5. The metal pipe fittings on the surface are subjected to certain treatment to prevent the oxides on the surface of the metal pipe fittings from re-adhering to the metal pipe fittings under the extrusion of the semi-annular plate 31, thereby affecting the subsequent processing of the metal pipe fittings. After the semi-annular plate 31 moves to the specified position, the driving assembly 6 drives the inner support assembly 7 to limit the metal pipe fittings through the aperture of the metal pipe fittings. During the limiting process, the metal pipe fittings can be driven to rotate so that the metal pipe fittings can be evenly sprinkled with cold water for cooling treatment. After the cooling is completed, the driving assembly 6 and the inner support assembly 7 are reset, and then the staff takes out the cooled metal pipe fittings. When the metal pipe fittings leave the semi-annular plate 31, the semi-annular plate 31 can be reset again under the action of the swinging assembly 5, so as to facilitate the cooling of the next metal pipe fitting.

[0039] Example 2

[0040] See also Figures 1 to 10 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0041] The processing chamber 2 is symmetrically provided with limit grooves 21, and the limit grooves 21 are engaged and slidably engaged with the limit rods 311. The processing chamber 2 is symmetrically provided with placement grooves 22, and the processing chamber 2 is symmetrically provided with elastic gaskets 23. The sealing plate 41 is internally provided with an array of telescopic rods 43. The telescopic rods 43 are used to support the trapezoidal plate 42 to prevent the trapezoidal plate 42 from positional displacement when moving. The telescopic rods 43 are externally provided with a second spring 44. The second spring 44 is used to provide elastic force to reset the trapezoidal plate 42 without external force.

[0042] The swing assembly 5 includes a corrugated guide rail 51 arranged inside the placement groove 22, a fixed plate 52 arranged on the side of the corrugated guide rail 51 close to the placement groove 22, and the fixed plate 52 is fixedly connected to the placement groove 22, the fixed plate 52 is used to support and fix the corrugated guide rail 51 to prevent the corrugated guide rail 51 from being unable to support when the circular clamping rod 36 moves along the corrugated guide rail 51, and also includes a fixed rod 53 arranged inside the placement groove 22, the fixed rod 53 is used to engage and slide with the square clamping plate 35, under the action of the notch opened inside the square clamping plate 35, the square clamping plate 35 will not be restricted in movement due to its own swing when moving, and a third spring 54 is sleeved on the outside of the fixed rod 53, the third spring 54 is used to reset the semi-ring plate 31 when there is no external force on the semi-ring plate 31, so as to facilitate the subsequent cooling of the metal pipe fittings.

[0043] The driving assembly 6 includes a driving motor 61 arranged on the processing chamber 2, a bidirectional screw rod 62 arranged on the driving motor 61, and a threaded sleeve 63 symmetrically arranged on the bidirectional screw rod 62. The threaded sleeve 63 is a kind of I shape, consisting of two circular plates and a connecting plate, so that the inner support assembly 7 can be moved laterally under the action of the threaded sleeve 63. The inner side of the threaded sleeve 63 has two circles of thread grooves that are threadedly connected to the bidirectional screw rod 62. When reaching the elastic gasket 23, the elastic gasket 23 will be squeezed and contracted, and the bidirectional screw rod 62 without thread grooves will be moved. When the threaded sleeve 63 and the bidirectional screw rod 62 are exposed, when the threaded connection is changed to a rotational connection, the elastic gasket 23 rebounds so that the threaded sleeve 63 is continuously in a forward and backward operation on the bidirectional screw rod 62, and the multi-stage sleeve rod 64 is fixedly connected to the drive motor 61, and is used to transmit the power of the drive motor 61 to the inner support assembly 7 through the conveyor belt 65. The multi-stage sleeve rod 64 is movably arranged on the side of the threaded sleeve plate 63 close to the drive motor 61, and the conveyor belt 65 is arranged on the multi-stage sleeve rod 64. The conveyor belt 65 is used to transmit power.

[0044] The inner support assembly 7 includes a circular rotating rod 71 movably arranged on the threaded sleeve plate 63, and a threaded groove is provided at one end of the circular rotating rod 71 for threaded connection with the threaded sleeve 73, so that when the threaded sleeve 73 moves, the inner support plate 75 can be unfolded to fix and lock the metal pipe fitting, a rotating shaft 72 is arranged at one end of the circular rotating rod 71, and the rotating shaft 72 is transmitted between the conveyor belt 65, and the rotating shaft 72 and the circular rotating rod 71 are fixedly connected to transmit power to the circular rotating rod 71 under the action of the conveyor belt 65, and also includes a threaded sleeve 73 arranged on the circular rotating rod 71, and the threaded sleeve 73 is used to be threadedly connected with the threaded section of the circular rotating rod 71, so that the rotating plate 74 is rotated under the movement of the threaded sleeve 73, the rotating plate 74 arranged on the threaded sleeve 73 in an array, and the inner support plate 75 arranged on the rotating plate 74 away from the end of the threaded sleeve 73. The inner support plate 75 is used to be unfolded under the rotation of the rotating plate 74, and to limit and lock the metal pipe fittings when the inner support plate 75 is unfolded. A rotating circular plate 76 is movably arranged on the end of the circular rotating rod 71 away from the rotating shaft 72, and a multi-stage extension rod 77 is arranged on the rotating circular plate 76. The multi-stage extension rod 77 is fixedly connected to the inner support plate 75 at one end away from the rotating circular plate 76. The multi-stage extension rod 77 is used to keep the inner support plate 75 horizontal in the vertical direction during the process of the inner support plate 75 being stretched out, so as to avoid angular deflection, which ultimately makes it impossible to lock and fix the metal pipe fittings.

[0045] During use, when the semi-ring plate 31 moves along the limit groove 21 with the metal pipe fitting, the impurity removing plate 34 arranged in the semi-ring plate 31 is limited by the square clamping plates 35 and the fixing rods 53 arranged on both sides, and the circular clamping rods 36 are engaged and slid with the corrugated guide rails 51, so that the impurity removing plate 34 swings back and forth. Under the swing of the impurity removing plate 34, the contacting side of the metal pipe fitting placed inside the semi-ring plate 31 is subjected to a certain treatment. Subsequently, after the semi-ring plate 31 reaches the predetermined position, the driving motor 61 is started, and the bidirectional screw rod 62 is rotated under the drive of the driving motor 61. The rotating bidirectional screw rod 62 can drive the threaded sleeve plate 63 to move, and the multi-stage sleeve rod 64 rotatably engaged on the threaded sleeve plate 63 is also fixedly connected to the driving motor 61. When the threaded sleeve plate 63 moves toward the elastic gasket 23, the inner side of the threaded sleeve plate 63 has two circles of thread grooves that are threadedly connected to the bidirectional screw rod 62. When it reaches the elastic gasket 23, When the threaded sleeve 63 and the two-way screw rod 62 are connected, the elastic gasket 23 will be squeezed and contracted, and the non-threaded groove part of the two-way screw rod 62 will be exposed. When the threaded connection between the threaded sleeve plate 63 and the two-way screw rod 62 is changed from a threaded connection to a rotational connection, the elastic gasket 23 rebounds so that the threaded sleeve plate 63 is continuously in an operation of moving forward and backward on the two-way screw rod 62, and the threaded conveying belt 65 transmits power to the circular rotating rod 71 to rotate the circular rotating rod 71, and the threaded sleeve 73 moves under the rotation of the circular rotating rod 71. As the threaded sleeve 73 moves, the rotating plate 74 rotatably connected to the threaded sleeve 73 is rotated, so that the inner support plate 75 set on the other side of the rotating plate 74 is opened, and the unfolded inner support plate 75 can limit and lock the metal pipe fitting, which is convenient for water cooling treatment. At the same time, the rotating metal pipe fitting can facilitate the cooling effect and the uniformity of cooling, and avoid the local stress of the metal pipe fitting due to different cooling degrees. Changes affect the quality of the entire metal pipe fitting.

[0046] The remaining structures are the same as those of Example 1.

[0047] Example 3

[0048] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0049] A circulating water tank 8 is provided on the operating table 1, and a delivery pipe 81 is provided on one side of the circulating water tank 8. Spray heads 82 are arranged in an array on the delivery pipe 81, and the spray heads 82 are located inside the processing chamber 2. The spray heads 82 are used to spray water on the metal pipe fittings to evenly cool the metal pipe fittings.

[0050] A recovery bin 9 is arranged on the side of the operating table 1 away from the processing bin 2, and a T-shaped plate 91 is symmetrically arranged inside the recovery bin 9, a screen 92 is arranged on the T-shaped plate 91, a reflux pipe 93 is arranged on one side of the recovery bin 9, and a water pump 94 is arranged on the end of the reflux pipe 93 away from the recovery bin 9.

[0051] After the inner support plate 75 completes locking the metal pipe, the inner support plate 75 will drive the metal pipe to rotate, so that the surface of the metal pipe can be evenly sprayed from the spray head 82. Under the action of the spray, the cooling of the metal pipe can be uniform, avoiding excessive temperature differences in the local area of ​​the metal pipe, which causes changes in the stress of the metal pipe. At the same time, the sprayed water will be filtered through the recovery bin 9, and the filtered water will enter the circulating water tank 8 again. This part of the water will be mixed and cooled inside the circulating water tank 8 to meet the cooling requirements of the metal pipe. Finally, the metal pipe will be taken out by the staff after cooling. The semi-ring plate 31 will be reset under the action of the third spring 54 in the absence of external force, which is convenient for the next cooling treatment of the metal pipe.

[0052] The remaining structures are the same as those of embodiments 1 and 2.

[0053] 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.
