Description

TECHNICAL FIELD

[0001] The present application relates to the field of water vector atomizing core manufacturing, in particular to a water vector atomizing core manufacturing method. BACKGROUND

[0002] The water vector atomizing core is a component for cooling tower, such as Figure 2 As shown in the figure, the existing vector atomizing core 10 includes a main body 21, a base 22 arranged at the bottom of the main body 21, a top cover 23 arranged at the top of the main body 21, and a plurality of round pipes 24 arranged on the outer side wall of the main body 21, and the end of any round pipe 24 is provided with a flange 25. The vector core is used to be installed in the cooling tower, and its function is to make the cooling water sprayed from each pipe opening in a specified direction (installing the same direction of the spray head on the flange) to form a thrust, so that the core rotates synchronously during the water spraying process, so that the cooling water is atomized during the spraying process to accelerate the heat dissipation and cooling of the cooling water.

[0003] The current water vector atomizing core material is composed of steel, and during manufacturing, the base 22, the top cover 23, and the round pipe 24 respectively located at the bottom, the top, and the outer side wall of the main body 21 are sequentially welded, and finally the flange 25 located at the end of the round pipe 24 is welded. In this way, it is ensured that the formed water vector atomizing core can meet the needs of high pressure of cooling water and convenient installation of other parts.

[0004] However, the water vector atomizing core manufactured by using the existing manufacturing method has the following problems: due to the too narrow distance between each round pipe on the outer side of the core body, the automatic welding of the mechanical hand cannot be realized, so manual welding is required, which leads to that the welding quality and manufacturing efficiency of the core depend on the experience of workers, and due to the excessive number of round pipes, the production efficiency of the water vector atomizing core is low and the cost is high. Therefore, in order to solve the above technical problems, the water vector atomizing core manufacturing method of the present application is proposed. SUMMARY

[0017] transferring the main body seat into the cavity of the carrier seat;

[0018] rotating the main body seat so that each of the through holes is aligned with each of the first half grooves;

[0019] respectively placing each of the pipe bodies into each of the first half grooves and pushing the pipe bodies to slide along the first half grooves, so that each of the buried joints is inserted into each of the through holes;

[0021] fastening the locking seat to the carrier seat, wherein each of the first half grooves is fastened with each of the second half grooves;

[0022] Each of the bolts is screwed through the locking seat and to the carrier, so that the locking seat and the carrier jointly press each of the embedded joints in each of the through holes.

[0023] In one of the embodiments, a plurality of detection surfaces are further formed on the edge of the carrier, each of the detection surfaces is perpendicular to the axis of each of the first half grooves, and when the end surface of the pipe body close to the embedded joint is attached to the outer side wall of the main body seat, the flange is attached to the detection surface.

[0024] In one of the embodiments, the step S3 of welding the end of each of the circular pipes to the inner side wall of each of the through holes includes the following steps.

DETAILED DESCRIPTION

[0044] For the purpose of facilitating the understanding of the present application, a more complete description of the present application will be given with reference to the accompanying drawings. The preferred embodiments of the present application are shown in the drawings.

[0045] As shown in Figure 2 and Figure 3 , a water vector atomizing core manufacturing method, in which the water vector atomizing core 10 comprises a main body seat 100, a top cover 23 and a plurality of flange water pipes 200, the main body seat 100 comprises a main body 21 and a base 22 located at the bottom of the main body 21, the flange water pipe 200 comprises a round pipe 24 and a flange 25 located at one end of the round pipe 24, the manufacturing method of the water vector atomizing core 10 comprises the following steps:

[0046] Step S1: forming a main body blank by pressure casting, machining a plurality of through holes 110 on the side wall of the main body blank by machining to obtain the main body seat 100.

[0047] Step S2: forming the top cover 23 and the plurality of flange water pipes 200 by pressure casting respectively.

[0048] Specifically, in steps S1 and S2, the main body blank, the top cover 23 and the flange water pipes 200 are respectively formed by the designed die casting mold in a die casting manner. The outer side wall of the main body blank is smooth and unperforated, and a plurality of through holes 110 are drilled on the outer side wall of the main body blank by machining to obtain the main body seat 100. It should be noted that, compared with the structure in the prior art that the main body seat 100 is fixed by welding between the main body 21 and the base 22, the main body seat 100 in the present application is integrally formed by die casting, which can not only enhance the structural strength of the joint position between the main body 21 and the base 22, but also effectively improve the manufacturing efficiency of the main body seat 100 by using die casting mold for batch production. Moreover, the main body seat 100 manufactured by die casting has a smoother surface. Similarly, the flange water pipes 200 are also integrally formed by die casting mold, and compared with the prior art that the round pipe 24 and the flange 25 are welded into one whole, the flange water pipes 200 manufactured by die casting can realize batch production, thereby improving the manufacturing efficiency of the flange water pipes 200. Moreover, the welding quality of the round pipe 24 and the flange 25 in the prior art depends on the experience and proficiency of workers, and the flange water pipes 200 manufactured by die casting mold have better consistency.

[0049] Step S3: The end of each round pipe 24 away from the flange 25 is respectively inserted into each through hole 110, and the end of each round pipe 24 and the inner side wall of each through hole 110 are respectively welded on the inner side of the main body seat 100.

[0050] Specifically, inserting each flange water pipe 200 into each through hole 110 means that the end of the round pipe 24 away from the flange 25 is inserted into the through hole 110, and then the welding gun is inserted into the inner side of the main body seat 100 to weld and fix the end of the round pipe 24 away from the flange 25 and the inner side wall of the through hole 110 by using the welding gun. It should be noted that, since each round pipe 24 is arranged in a circle on the outer side wall of the main body seat 100, the distance between any two adjacent round pipes 24 is too narrow. In this embodiment, the distance between any two round pipes 24 at the position of the main body seat 100 is 4.4 mm. Since the distance is too small, the welding gun cannot be automatically welded by the manipulator, so manual welding is the only way. When the number of flange water pipes 200 increases, the distance between any two adjacent flange water pipes 200 will be smaller, which will further increase the difficulty of automatic welding. In the present application, the welding gun is inserted into the inner side of the main body seat 100 for welding, so that the interference of each round pipe 24 on the outer side of the main body seat 100 can be avoided, which not only meets the manual welding of workers, but also meets the automatic welding by using the manipulator to drive the welding gun. In this way, the welding efficiency between the flange water pipes 200 and the main body seat 100 can be effectively improved.

[0051] Step S4: buckling the top cover 23 on the top of the main body seat 100 and welding, to obtain the water vector atomization machine core 10.

[0052] Specifically, after all the flange water pipes 200 are welded, the top cover 23 is buckled on the top of the main body seat 100, and finally the top cover 23 is welded and fixed with the main body seat 100, to obtain the finished water vector atomization machine core 10.

[0053] It should be noted that the existing water vector atomization machine core 10 needs to weld the main body 21 and the base 22, weld the main body 21 and the circular pipe 24, weld the circular pipe 24 and the flange 25, and weld the main body 21 and the top cover 23, that is, 4 times of welding are needed to complete the welding of a single flange water pipe 200, while the manufacturing method provided in the present application only needs to weld the main body seat 100 and the flange water pipe 200, and weld the main body seat 100 and the top cover 23, that is, only 2 times of welding are needed to complete the welding of a single flange water pipe 200. In particular, since the flange water pipe 200 has a certain number, the embodiment shown in the figure has 16 flange water pipes 200, and for each flange water pipe 200 to complete the welding, the existing manufacturing method needs to increase 2 times of welding, while the manufacturing method of the present application only needs to increase 1 time of welding. Therefore, for manufacturing the water vector atomization machine core 10 with 16 flange water pipes 200, the existing manufacturing method needs to weld at least 34 times (under the condition that each welding does not need to be reworked), while the manufacturing method of the present application only needs to weld 18 times. When the number of flange water pipes 200 is larger and the yield of water vector atomization machine core 10 is larger, the difference between the two manufacturing methods will be further enlarged. Therefore, by using the water vector atomization machine manufacturing method provided in the present application, the number of weldings can be effectively reduced, so as to improve the manufacturing efficiency of the water vector atomization machine core 10 and reduce the manufacturing cost. Moreover, automatic welding can be realized by using a mechanical hand to drive a welding gun, which can further reduce the labor cost.

[0054] In an embodiment, after the machining is adopted to form a plurality of through holes 110 on the side wall of the main body blank in step S1, the embodiment further includes polishing the inner and outer edges of each through hole 110, respectively.

[0055] Specifically, in order to enable the flange water pipe 200 to be smoothly inserted into the through hole 110 and avoid burrs and burrs generated during machining of the through hole 110 from hindering the flange water pipe 200, the edges of both ends of the through hole 110 are polished. Further, by polishing the inner edges of the through holes 110 and the edges inside the main body seat 100 smooth, it is beneficial to subsequent welding.

[0056] As shown in FIG. 1, Figures 3 to 5 In an embodiment, the circular pipe 24 includes a pipe body 241 and a buried joint 242 arranged at one end of the pipe body 241, and the flange 25 is located at one end of the pipe body 241 away from the buried joint 242.

[0057] Specifically, the outer diameter of the embedded joint 242 is adapted to the inner diameter of the through hole 110, so that when the embedded joint 242 is inserted into the through hole 110 and pushed to the limit position, the end of the pipe body 241 will abut against the outer side wall of the main body seat 100, so that it indicates that the flange water pipe 200 has been inserted into place, and thus facilitates the welding installation of the flange water pipe 200. Secondly, through the embedded joint 242, the welding sealing between the flange water pipe 200 and the main body seat 100 can be improved. It should be noted that the pipe body 241, the embedded joint 242 and the flange 25 are integrally formed by pressure casting.

[0058] In an embodiment, the width of the embedded joint 242 is less than or equal to the depth of the through hole 110. In this way, when the embedded joint 242 is inserted into the through hole 110, the end face of the embedded joint 242 away from the pipe body 241 is either flush with the inner side wall of the main body seat 100 or located in the through hole 110. When the end face of the embedded joint 242 is located in the through hole 110, that is, the embedded joint 242 has a certain distance from the inner side wall of the main body seat 100, the embedded joint 242 can be stably and reliably welded and fixed to the main body seat 100, thereby improving the welding stability of the flange water pipe 200.

[0059] As shown in FIGS. 1, 2 and 3, in an embodiment, the step of inserting the pipe body 241 into the through hole 110 in step S3 is specifically as follows: Figure 1 Figure 6 As shown in FIGS. 1, 2 and 3, in an embodiment, the step of inserting the pipe body 241 into the through hole 110 in step S3 is specifically as follows:

[0060] A welding device 300 is provided, wherein the welding device 300 comprises a carrier seat 310, a locking seat 320 and a plurality of bolts 330, the carrier seat 310 is provided with a cavity 311 for accommodating the main body seat 100, and a plurality of first half grooves 312 are further provided around the carrier seat 310, and a plurality of second half grooves 321 are provided around the locking seat 320;

[0061] The main body seat 100 is transferred into the cavity 311 of the carrier seat 310;

[0062] The main body seat 100 is rotated so that each through hole 110 is aligned with each first half groove 312;

[0063] Each pipe body 241 is placed into each first half groove 312 and the pipe body 241 is pushed to slide along the first half groove 312, so that each embedded joint 242 is inserted into each through hole 110;

[0064] The pipe body 241 is rotated until the end face of the pipe body 241 close to the embedded joint 242 is attached to the outer side wall of the main body seat 100;

[0065] The locking seat 320 is buckled onto the carrier seat 310, wherein each first half groove 312 is buckled with each second half groove 321.​

[0066] Each bolt 330 is threaded through the locking seat 320 and screwed to the carrier 310, so that the locking seat 320 and the carrier 310 together press each embedded joint 242 against each through hole 110.

[0067] It should be noted that, since the flange water pipe 200 and the outer side wall of the main body seat 100 have the same included angle, in order to improve the welding efficiency of the flange water pipe 200, that is, to make each flange water pipe 200 can be reliably fixed in the through hole 110 for unified welding, a welding device 300 is provided to assist manufacturing. Specifically, the welding device 300 is composed of a carrier 310, a locking seat 320 and a plurality of bolts 330. First, the locking seat 320 is removed from the carrier 310, and then the main body seat 100 is transferred to the cavity 311 in the carrier 310 for positioning. Then rotate the main body seat 100, so that each through hole 110 of the main body seat 100 is aligned with each first half groove 312, and then each flange water pipe 200 is inserted into each through hole 110 along the first half groove 312. Then buckle the locking seat 320 on the carrier 310, wherein each second half groove 321 on the locking seat 320 is aligned and buckled with each first half groove 312, so that the inner side wall of the second half groove 321 and the inner side wall of the first half groove 312 together clamp the pipe body 241. Finally, each bolt 330 is threaded through the locking seat 320 and then screwed and fixed with the carrier 310, so that the flange water pipe 200 and the main body seat 100 are fixed as a whole. In this way, simultaneous fixing of multiple flange water pipes 200 is realized, thereby facilitating automatic welding by the welding gun driven by the robot.

[0068] In an embodiment, the carrier 310 and the locking seat 320 are both metal structures and have a certain weight. In order to improve the automatic manufacturing level of the water vector atomizing machine core 10 and make the locking seat 320 realize automatic pressing or separation, the carrier 310 is fixed on the machine table, the locking seat 320 is fixed on the elevator, and the locking seat 320 and the carrier 310 are aligned along the vertical direction. In this way, the locking seat 320 is quickly buckled or separated from the carrier 310 by the elevator.

[0069] As shown in Figure 6 In an embodiment, a plurality of detection surfaces 313 are also provided on the edge of the carrier 310, each detection surface 313 is perpendicular to the axis of each first half groove 312, and when the end face of the pipe body 241 close to the embedded joint 242 is attached to the outer side wall of the main body seat 100, the flange 25 is attached to the detection surface 313.

[0070] It should be noted that when the end face of the pipe body 241 close to the embedded joint 242 is attached to the outer side wall of the main body seat 100, it indicates that the flange water pipe 200 is inserted into the through hole 110 in place. However, since the main body seat 100 is located in the carrier seat 310, it is difficult to detect and determine whether the pipe body 241 is tightly attached to the outer side wall of the main body seat 100, especially since the lock pressure seat 320 is located above the carrier seat 310, if you observe by stretching into the carrier seat 310, there is a great security risk, therefore, in order to eliminate this security risk, a plurality of detection faces 313 are provided on the outer side of the carrier seat 310, wherein each detection face 313 is perpendicular to the axis of each first half groove 312, so that when the flange water pipe 200 is rotated, whether the flange 25 is tightly attached to the detection face 313 can be determined by observing whether the flange 25 is tightly attached to the detection face 313.

[0071] As shown in Figure 6 and Figure 7 In an embodiment, the welding device 300 further comprises a plurality of lock rod groups, each lock rod group comprising at least two lock rods 341, and at least two lock holes 314 are provided on the detection face 313, when the flange 25 is attached to the detection face 313, the through hole of each flange 25 is aligned with the lock hole 314 of the corresponding detection face 313, and each lock rod 341 is used to pass through the through hole of the flange 25 and is screwed into the lock hole 314 on the corresponding detection face 313.

[0072] It should be noted that in order to further improve the stability of the flange water pipe 200 and the base 22 during welding, the lock rod 341 is provided to pass through the through hole of the flange 25 and is screwed on the carrier seat 310. In an embodiment, two lock holes 314 are provided on the detection face 313, and the lock rod group comprises two lock rods 341, and the two lock rods 341 correspond to the two lock holes 314. It should be noted that since the outer side wall of the main body seat 100 has a curvature, in order to make the end face of the circular pipe 24 tightly attached to the outer side wall of the main body seat 100, the end face of the circular pipe 24 also has a curvature, so that by setting the depth of the first half groove 312 of the carrier seat 310, when the end face of the circular pipe 24 is tightly attached to the outer side wall of the main body seat 100, the flange 25 is attached to the detection face 313, and at the same time, the through hole of the flange 25 is aligned with the lock hole 314 on the attached detection face 313. In this way, by observing the attachment of the flange 25 to the detection face 313 and the alignment of the through hole of the flange 25 with the lock hole 314, it can be ensured that the end face of the circular pipe 24 is tightly attached to the outer side wall of the main body seat 100.

[0073] In an embodiment, in step S3, the end of each circular pipe 24 is welded to the inner side wall of each through hole 110 on the inner side of the main body seat 100, comprising the following steps:

[0074] The through holes 110 are sequentially numbered as 1-n in clockwise / anticlockwise direction, where n is a natural number.

[0075] The inner side walls of the through holes 110 are sequentially welded with the buried connectors 242 in a first-single-second-single / second-single-first-single mode or a circumferentially symmetric staggered mode.

[0076] Specifically, the welding can be performed in the following two modes:

[0077] Firstly, the through holes 110 are sequentially numbered as 1-n in clockwise / anticlockwise direction, where n is a natural number; the inner side walls of the through holes 110 are sequentially welded with the buried connectors 242 in a first-single-second-single / second-single-first-single mode.

[0078] Secondly, the through holes 110 are sequentially numbered as 1-n in clockwise / anticlockwise direction, where n is a natural number; the inner side walls of the through holes 110 are sequentially welded with the buried connectors 242 in a circumferentially symmetric staggered mode.

[0079] It should be noted that, for the first mode, taking n=16 as an example, the through holes 110 are sequentially numbered as 1-16; the first-single-second-single mode means that the flange water pipe 200 is sequentially welded with the main body seat 100 in the order of 1, 3, 5, 7, 9, 11, 13, 15, 2, 4, 6, 8, 10, 12, 14, 16; the second-single-first-single mode means that the flange water pipe 200 is sequentially welded with the main body seat 100 in the order of 2, 4, 6, 8, 10, 12, 14, 16, 1, 3, 5, 7, 9, 11, 13, 15. In this way, the temperature of the previous welding position is prevented from being rapidly transferred to the next welding position through interval welding, thereby improving the welding quality of the water vector atomizing machine core 10. For the second mode, taking n=16 as an example, the through holes 110 are sequentially numbered as 1-16; the circumferentially symmetric staggered mode means that the flange water pipe 200 is sequentially welded with the main body seat 100 in the order of 1, 9, 2, 10, 3, 11, 4, 12, 5, 13, 6, 14, 7, 15, 8, 16. In this way, the temperature change of the main body seat 100 is circumferentially symmetric, and the stress deformation of the main body seat 100 caused by excessive temperature deviation of the overall structure during welding is avoided.

[0080] In an embodiment, the inner side walls of the through holes 110 and the buried connectors 242 are welded by argon arc welding. For example, the inner side walls of the through holes 110 and the buried connectors 242 are welded by shielded metal arc welding.

[0081] In one embodiment, the welding current of the buried joint 242 and the inner side wall of the through hole 110 is 220A-520A, the welding arc voltage is 24V-40V, and the welding speed is 30m / h-110m / h. For example, the welding current can also be 350A, the welding arc voltage is 30V, and the welding speed is 40m / h.

[0082] In one embodiment, the top cover 23 and the top of the main body seat 100 are welded by friction stir welding. In this way, the side edge of the top cover 23 is welded and fixed to the top of the main body seat 100 by friction stir welding. The parameters of the friction stir welding are as follows: the pin length of the stirring pin is 8mm-12mm, the shoulder of the stirring pin is 6mm-8mm, the side surface inclination angle of the stirring pin is 3°-6°, the rotation speed of the stirring head is 450r / min-850r / min, the welding speed is 110mm / min-145mm / min, and the welding pressure is 25KN-38KN. In one embodiment, the parameters of the friction stir welding are as follows: the pin length of the stirring pin is 9mm, the shoulder of the stirring pin is 7mm, the side surface inclination angle of the stirring pin is 4°, the rotation speed of the stirring head is 600r / min, the welding speed is 120mm / min, and the welding pressure is 32KN.

[0083] In one embodiment, the water vector atomization core 10 is an aluminum alloy structure, that is, the main body seat 100, the top cover 23, and the flange water pipe 200 are all aluminum alloy structures. In this way, compared with the existing steel structure, the parts of the water vector atomization core 10 are manufactured by die casting, and at the same time, better corrosion resistance can be achieved, avoiding rusting and corrosion problems in long-term use.

[0084] It should be noted that the drawings in the present application show that each flange water pipe 200 is circumferentially distributed on the outer side wall of the main body seat 100 in a single-layer structure, but this should not be understood as a limitation on the structure of the water vector atomization core 10. When each flange water pipe 200 is circumferentially distributed on the outer side wall of the main body seat 100 in a double-layer or more layers structure, it is more difficult to realize automatic welding operation by a robot according to the conventional welding method. Therefore, compared with the conventional welding method, the manufacturing method of the present application can more effectively improve the manufacturing efficiency and reduce the manufacturing cost.

[0085] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
