Description

Technical Field

[0001] The present application relates to the technical field of flux production, and specifically to a flux production device for welding and a method for using the same. Background Art

[0002] Flux is a granular welding material that can melt to form slag and gas during welding, which plays a protective and metallurgical role in the molten pool. It includes molten salt, organic matter, active gas, metal vapor, etc., that is, in addition to the base material and solder, it generally refers to the third substance used to reduce the interfacial tension between the base material and the solder.

[0003] The flux has certain requirements for its particle size. The particle size of the flux should be appropriate so that the flux has a certain air permeability, does not emit continuous arc light during the welding process, and can avoid air contamination of the molten pool and the formation of pores.

[0004] Flux is generally divided into two types according to particle size. One is ordinary particle size 2.5-0.45mm (8-40 mesh), and the other is fine particle size 1.43-0.28mm (10-60 mesh). Fine powder smaller than the specified particle size is generally not more than 5%, and coarse powder larger than the specified particle size is generally more than 2%.

[0005] With regard to the above-mentioned related technologies, since powder materials are added in batches during the mixing production of the flux in a mixing barrel, it is difficult to completely mix the materials by relying solely on the stirring rod or the rotation of the mixing barrel, which will cause problems with the proportions of some materials and affect the use effect of the flux. At the same time, since the particle size of the flux mixture is small, after mixing, a large amount of dust is likely to adhere to the inner wall of the mixing barrel, which will seriously affect the mixing ratio of the next batch of flux materials. Ordinary washing will consume a lot of time and energy, which is not conducive to the mass production of flux. Summary of the invention

A plurality of guide grooves 551 are provided on the surface of the rotating cylinder 55, and the plurality of guide grooves 551 are evenly distributed along the circumference of the rotating cylinder 55. The shifting rod 56 is fixedly installed on the upper end of the rotating cylinder 55, and the plurality of shifting rods 56 are evenly distributed along the circumference of the rotating cylinder 55. The abutting rod 561 is installed on the upper end of the shifting rod 56, and the abutting rod 561 is connected to the shifting rod 56 through a spring, and the abutting rod 561 contacts the side wall of the displacement block 54. The curved plate 541 is fixedly installed on one end of the displacement block 54 close to the abutting rod 561, and a limiting groove 542 that can be engaged with the abutting rod 561 is provided on the outer wall of the displacement block 54 and close to the curved plate 541. The abutting rod 561 can slide on the curved plate 541 and be engaged with the limiting groove 542. When the abutment rod 561 is engaged with the limit slot 542, the abutment rod 561 and the reset plug rod 521 are in the same straight line. The upper end of the external slide bar 57 is inserted into the guide groove 551 on the surface of the rotating drum 55, and the external slide bar 57 can be displaced along the track of the guide groove 551. The lower end of the external slide bar 57 is fixedly connected to the telescopic displacement plate 533.

The fixed float plate 581 is fixedly installed at the lower end of the internal slide bar 58. The annular fixed float plate 581 slides inside the nozzle 4, and a plurality of internal slide bars 58 are evenly distributed on the upper end surface of the fixed float plate 581 along the circumference of the fixed float plate 581. The lower end surface of the fixed float plate 581 is set as a concave curved surface to increase the area of ​​the lower end surface of the fixed float plate 581. The fixed beam 59 is fixedly installed on the lower end surface of the fixed float plate 581 and close to the nozzle 41. The fixed beam 59 is attached to the inner side wall of the nozzle 4 and is slidably connected to the inner side wall of the nozzle 4 through the flange. A plurality of closed baffles 592 are evenly fixedly installed on the inner side of the fixed beam 59 and close to the nozzle 41 along the length direction of the fixed beam 59, and are used to block the nozzle 41.

[0040] Installation and disassembly of linkage mechanism 5:

[0041] When the nozzle 4 is not plugged into the socket 3 for fixing, the telescopic sleeve 532 at the lower end of the connection seat 51 is in an extended state, and the external slide bar 57 is at the lowest point of the guide groove 551 on the surface of the rotating cylinder 55. When the external slide bar 57 is at the lowest point, the rotating cylinder 55 will rotate to the original position due to the action of the torsion spring, and the abutment rod 561 at the upper end of the rotating cylinder 55 will contact the curved plate 541 on one side of the displacement block 54. At the same time, the internal slide bar 58 is also at the lowest point inside the nozzle 4, and the closed baffle 592 on the fixed beam 59 blocks the nozzle 41;

[0042] Before the mixing barrel 1 mixes the flux material, the nozzle 4 is inserted into the mixing barrel 1 from the socket 3. As the nozzle 4 is inserted, the telescopic displacement plate 533 and the inner side wall of the socket 3 are pressed against each other, and the telescopic displacement plate 533 moves in the direction of the telescopic fixing ring 531, and at the same time, the telescopic sleeve 532 is pressed, so that the telescopic sleeve 532 is compressed. As the telescopic displacement plate 533 is displaced, the external sliding rod 57 fixedly connected to the telescopic displacement plate 533 moves upward synchronously with the telescopic displacement plate 533, and the external sliding rod 57 slides along the guide groove 551 in the guide groove 551 on the surface of the rotating drum 55. The rotating drum 55 rotates when the external sliding rod 57 moves. When the rotating drum 55 rotates, the abutting rod 561 located at the upper end of the rotating drum 55 moves along the curved plate 541. The abutting rod 561 slides on the curved plate 541 and pushes the displacement block 54 to move. The displacement block 54 slides in the through groove on the surface of the telescopic fixing ring 531, and as the abutment rod 561 is displaced, the displacement block 54 moves toward the slot 31 on the inner wall of the socket 3. When the abutment rod 561 engages with the limiting slot 542 on the surface of the displacement block 54, the displacement block 54 is just plugged into the slot 31 on the inner wall of the socket 3. It should be noted that the lever 56 is an elastic member, and when the abutment rod 561 is displaced along the curved plate 541, the force between the abutment rod 561 and the curved plate 541 increases, and the lever 56 gradually bends until the abutment rod 561 engages with the limiting slot 542. Then, the lever 56 presses the displacement block 54 into the slot 31 and returns to the state before deformation. In this way, the nozzle 4 is fixedly installed inside the socket 3;

[0043] When the nozzle 4 needs to be removed, the reset button 52 is pressed down, and the reset rod 521 at the lower end of the reset button 52 moves downward, and the reset rod 521 that moves downward squeezes the abutment rod 561 at the upper end of the lever 56. Since the abutment rod 561 is connected to the lever 56 by a spring, when the reset rod 521 squeezes the abutment rod 561, the abutment rod 561 will move toward the lever 56. When the upper end surface of the abutment rod 561 is completely lower than the lower end surface of the displacement block 54, the abutment rod 561 will be separated from the engagement connection with the limit slot 542, and the rotating cylinder 55 will rotate to the original position under the action of the torsion spring, and the displacement block 54 will also be displaced toward the inside of the telescopic fixing ring 531 under the action of the spring sheet, so that the displacement block 54 is separated from the engagement connection with the slot 31. In this way, the nozzle 4 can be separated from the fixed connection with the socket 3.

[0044] When the mixing barrel 1 is working, the working state of the linkage mechanism 5 is:

[0045] While the linkage mechanism 5 is being installed, the opening and closing states of the nozzle 41 will be completed synchronously. The external magnet 571 and the internal magnet 582 attract each other. Under the traction of the internal magnet 582 and the external magnet 571, the internal slide bar 58 located inside the nozzle 4 will move upward along with the upward movement of the external slide bar 57. The fixed beam 59 and the fixed floating plate 581 move upward along with the internal slide bar 58, while the closed baffle 592 moves upward along with the fixed beam 59, opening the air inlet of the nozzle 41 so that the inner cavity of the nozzle 4 is connected to the inner cavity of the mixing barrel 1. When the mixing barrel 1 mixes the flux material, the connecting seat 51 is externally connected to an air pump, and the air pump passes the gas into the nozzle 4, and the gas is sprayed into the mixing barrel 1 by the nozzle 41. The airflow brought by the spray gas stirs the flux mixture in the mixing barrel 1, and the auxiliary stirring rod 12 and the mixing barrel 1 stir the flux material;

[0046] It is also possible that after the mixed materials in the mixing barrel 1 are mixed and the materials are taken out, gas is continuously introduced into the nozzle 4, and the inner wall of the mixing barrel 1 is blown by the high-speed airflow to blow off the materials adhering to the inner wall of the mixing barrel 1, thereby reducing the flux materials adhering to the inner wall of the mixing barrel 1, reducing the thickness of the materials adhering to the inner wall of the mixing barrel 1, reducing the material loss, and reducing the difficulty of cleaning the inner wall of the mixing barrel 1. When thorough cleaning is required, cleaning water is introduced into the nozzle 4 through the connecting seat 51, and the inner wall of the mixing barrel 1 is flushed by the high-speed water flow to clean the mixing barrel 1.

[0047] A method for using a flux production device for welding, comprising the following steps:

[0048] S1. Installation, insert the nozzle 4 into the socket 3 on the top cover 2. During the insertion process, the telescopic sleeve 532 is compressed, the external slide bar 57 moves up along the guide groove 551 and pushes the rotating drum 55 to rotate, so that the abutment rod 561 is engaged in the limit groove 542, and the displacement block 54 is inserted into the slot 31. The internal slide bar 58 moves up with the external slide bar 57 under the magnetic traction of the internal magnet 582 and the external magnet 571, so that the closed baffle 592 moves upward, opens the channel of the nozzle 41, and connects the inner cavity of the nozzle 4 with the inner cavity of the mixing barrel 1, completing the installation of the linkage mechanism 5;

[0049] S2. Auxiliary stirring, an air pump is connected to the inlet end of the connection seat 51, and the air pump is used to pass gas into the nozzle 4, and the gas is then passed into the mixing barrel 1 through the nozzle 41, and the high-speed airflow assists the mixing barrel 1 and the stirring rod 12 to mix the mixed materials;

[0050] S3. Auxiliary cleaning: After the mixing is completed, continue to introduce gas into the nozzle 4, use the high-speed airflow to flush the inner wall of the mixing barrel 1, reduce the material residue on the barrel wall, and then replace the air pump with a water pump, introduce cleaning water into the nozzle 4, use the high-speed water flow to flush the barrel wall of the mixing barrel 1, and further clean the residual material in the mixing barrel 1;

[0051] S4. After disassembly, mixing and cleaning are completely completed, the reset button 52 is pressed downward to displace the reset rod 521 downward and squeeze the abutment rod 561, so that the abutment rod 561 is disengaged from the limit slot 542, the displacement block 54 is reset and received into the telescopic fixing ring 531, and then the rotating cylinder 55 is reset under the action of the torsion spring, and the nozzle 4 is pulled out from the socket 3, and the disassembly is completed.

[0052] The working principle of the embodiment of this application:

[0053] The nozzle 4 is inserted into the mixing barrel 1 through the socket 3. As the nozzle 4 is inserted, the telescopic sleeve 532 is compressed, and the telescopic displacement plate 533 moves in the direction of the telescopic fixing ring 531. The external slide bar 57 moves upward along with the telescopic displacement plate 533, and moves along the guide groove 551 on the rotating drum 55. When the external slide bar 57 moves, the rotating drum 55 is driven to rotate. The abutment rod 561 moves along the curved plate 541 to the position of the limiting card groove 542, and the abutment rod 561 is engaged with the limiting card groove 542, and the displacement block 54 is pushed to the position of the slot 31, so that the displacement block 54 is inserted into the slot 31. When disassembling, the reset button 52 is pressed, so that the reset plug 521 presses down the abutment rod 561, contacts the engagement of the abutment rod 561 and the limiting card groove 542, and the displacement block 54 is reset after being separated from the slot 31. Since the inner magnet 582 of the inner slide bar 58 and the outer magnet 571 of the outer slide bar 57 attract each other, when the outer slide bar 57 moves upward, the inner slide bar 58 moves upward synchronously, driving the closing baffle 592 to move upward, and the nozzle 41 outside the nozzle 4 is opened when the nozzle 4 is installed. Then, according to work needs, gas or cleaning water is introduced into the nozzle 4 to assist the mixing barrel 1 in stirring the mixed materials and clean the inner wall of the mixing barrel 1.
