[0001] The present invention relates to a field of precision laser welding for a reactor. Background Art
[0002] Reactors are key equipment commonly used in the fields of petroleum, chemical industry, medicine, etc., used to complete various chemical reactions such as sulfidation, nitration, and hydrogenation. The quality of their welding is directly related to the sealing, safety and service life of the equipment. Therefore, extremely high requirements are placed on the accuracy and reliability of the welding process.
[0003] In the existing laser welding process for reactor processing, the workpiece to be welded is first placed on a designated mounting seat for fixation or clamped by a clamping mechanism on the mounting seat for circular rotation, and then the laser welding head is used for welding. However, in this process, the molten molten pool generated during laser welding is prone to cover the unwelded or welded but not yet solidified molten pool, causing the molten pool metal to flow excessively to the unwelded area, forming a "bite" at the edge of the weld (the parent material is melted but not filled, forming a groove), weakening the bonding strength between the weld and the parent material; if it flows to the welded but not solidified area, it may accumulate to form a "weld nodule", resulting in an uneven weld surface, affecting the sealing and pressure-bearing capacity of the reactor.

[0008] As a further solution of the present invention: a rectangular rod is fixedly connected to the inner side of the U-shaped seat, a rectangular groove matching the rectangular rod is opened on the inner side of the sliding block, and the sliding block is slidably connected to the rectangular rod through the rectangular groove opened on the inner side.
[0009] As a further solution of the present invention: a cavity is provided on the inner side of each of the two inclined plates, and a heating component is installed inside the cavity, and a through groove is provided on the inner side of one of the inclined plates, which is respectively connected to the baffle plate and the cavity.
[0010] As a further solution of the present invention: the impact unit includes an L-shaped seat fixedly connected to the side wall of the U-shaped seat, the inner side of the L-shaped seat is slidably connected to a sliding rod, one end of the sliding rod passes through the outside of the L-shaped seat and is fixedly connected to an impact block, and the impact block is against the outer wall of the sliding block, and a connecting spring is installed between the L-shaped seat and the impact block.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the cooperation of parts such as the baffle plate, when the molten pool metal flows to the welded part, it is blocked by the baffle plate, and at the same time the drive motor is started. The output end of the drive motor drives the connecting column to drive the reciprocating screw to rotate, and then drives the sliding block to drive the baffle plate to move back and forth horizontally, so that the excessively accumulated molten pool metal can actively flow to both sides of the weld edge under the movement of multiple shifting blocks, so that it will not cover the welded but not yet solidified part, significantly reducing the incidence of defects such as incomplete fusion, pores, cracks, etc., thereby improving the overall practicality of the device; 2. By setting up the cooperation of parts such as inclined plates, when the laser welding head welds the parts of the support that need to be welded, two inclined plates are tilted on both sides of the laser welding head to block the molten pool metal generated by welding, reducing the molten pool metal from flowing to the welds on both sides, so that the accumulated molten pool metal can flow to the weld edges where there is no obstruction. This guidance allows the molten pool metal to fill the weld more evenly, avoiding forming defects such as uneven welds and excessive excess height caused by uneven flow, thereby improving the quality after welding; 3. By setting up the cooperation of parts such as the fixing ring, when the connecting column rotates, it drives the fixing ring to rotate as well. When the roller moves from the lowest point of the triangular block to the highest point, the impact block gradually moves away from the sliding block from the side of the sliding block. When the roller is separated from the triangular block, the connecting spring drives the impact block to reset, so that the impact block hits the sliding block, so that the baffle plate and the paddle block resonate to act on the contacted molten metal pool. After the vibration is transmitted to the contacted molten metal pool, the tension on the surface of the molten pool can be destroyed, so that the internal bubbles can escape and the welding defects such as pores can be reduced. The vibration generated by the resonance can accelerate the convection of the molten pool metal, so that the alloy elements are mixed more evenly. At the same time, the auxiliary paddle block pushes the molten pool metal to flow to the edge of the weld, further optimizing the metal distribution and improving the density and mechanical properties of the weld. 4. By setting up the cooperation of parts such as the air jet groove, when the molten molten pool metal generated at the welding part of the laser welding head flows to both sides, and when the molten molten pool metal flows to the unwelded part, the air pump delivers high-pressure gas to the inside of the air jet groove, so that the high-pressure gas is ejected, and the molten pool metal that has not yet been welded and has not solidified is blown to the edge of the weld and blocked by the blocking frame, so as to prevent the molten pool metal from being blown too far and reduce the tediousness of subsequent grinding. At the same time, through the above operation, the molten pool metal is blown away when it flows to the unwelded part and has not solidified, forming an "air curtain barrier" at the edge of the weld, which generates a lateral thrust on the molten pool metal flowing toward the unwelded area, preventing the molten pool metal from overflowing to the surface of the base material in the unwelded area, and avoiding the formation of metal nodules or adhesion spots. The combination of the blocking frame and the air pump realizes the fine control of the flow of the molten pool metal through the synergistic effect of "air curtain blocking + heat conduction anti-solidification + physical guidance", which can not only improve the weld quality and forming accuracy.

The bottom of the sliding block 14 is fixedly connected to a baffle plate 11, and the inner side of the baffle plate 11 is fixedly connected to a plurality of material blocks 23. The plurality of material blocks 23 are equidistantly distributed on the inner side of the baffle plate 11. A drive motor 17 is installed on one side of the U-shaped seat 15, and the drive motor 17 is The output end passes through the inner side of the U-shaped seat 15 and is fixedly connected to the connecting column 21. A rectangular rod 26 is fixedly connected to the inner side of the U-shaped seat 15. A rectangular groove matching the rectangular rod 26 is opened on the inner side of the sliding block 14. The sliding block 14 is slidably connected to the rectangular rod 26 through the rectangular groove opened on the inner side. A cavity is opened on the inner side of each of the two inclined plates 10, and a heating component 24 is installed inside the cavity. A through groove 22 is opened on the inner side of one of the inclined plates 10, which communicates with the baffle plate 11 and the cavity respectively. This solution does not describe in detail how to drive the welding workpiece 6 to rotate during the welding operation or how to adjust the position of the laser welding head 3 for the welding operation. These are all common knowledge that has been disclosed in the prior art, so this solution does not go into too much detail. This solution is for the laser welding head to perform welding operations. However, in this process, the molten molten pool generated during the laser welding process is easy to cover the molten pool that has not been welded or has been welded but not yet solidified. When the molten pool metal flows excessively to the unwelded area, it will form a "bite" at the edge of the weld (the parent material is melted but not filled, forming a groove), weakening the bonding strength between the weld and the parent material; if it flows to the welded but unsolidified area, it may accumulate to form a "weld nodule", resulting in an uneven weld surface, affecting the sealing and pressure-bearing capacity of the reactor. In response to the above technical problem, the following improvements are performed: The heating assembly 24 can be composed of a high-frequency induction coil or the like for heating components, and can heat the inclined plate 10. Since it is a prior art, this solution does not elaborate on it in detail. The inclined plate 10 and the baffle plate 11 are both made of metal materials and have high temperature resistance. First, when the laser welding head 3 welds the parts of the support base 5 that need to be welded, two inclined plates 10 are obliquely arranged on both sides of the laser welding head 3 to block the molten pool metal generated by welding, reducing the molten pool metal from flowing to the welds on both sides, so that the accumulated molten pool metal can flow to the edges of the welds where there is no obstruction. This guidance allows the molten pool metal to fill the weld more evenly, avoiding forming defects such as uneven welds and excessive excess height caused by uneven flow, thereby improving the quality of the weld. The heating components 24 on the inner sides of the two inclined plates 10 heat them to increase their temperature, so as to prevent the molten pool metal produced by welding from cooling and solidifying after contacting the two inclined plates 10; In the prior art, the molten pool metal generated during the welding process of the laser welding head 3 easily covers the molten pool of the welded part but not yet solidified, which easily leads to the inability of the new and old molten pool metals to fully fuse due to the temperature difference, forming a weak bonding surface. When the metal cools rapidly, the internal gas cannot escape, forming pores, and the stress concentration leads to cracking of the weld. Therefore, the specific operations after optimization and improvement of this solution based on this problem are as follows: When the inclined plate 10 is heated, the heat conduction causes the baffle plate 11 to be in a heated state as well, thereby preventing the molten pool metal from solidifying on the baffle plate 11. When the molten pool metal flows to the welded part, it is blocked by the baffle plate 11, and the driving motor 17 is started at the same time. The output end of the driving motor 17 drives the connecting column 21 to drive the reciprocating screw rod 27 to rotate, and then drives the sliding block 14 to drive the baffle plate 11 to move back and forth laterally, so that the excessively accumulated molten pool metal can actively flow to both sides of the weld edge under the action of multiple prying blocks 23, so that it will not cover the welded but not yet solidified part, significantly reducing the incidence of defects such as unfusion, pores, cracks, etc., thereby improving the overall practicality of the device; See also Figures 5 to 8, one side of the U-shaped seat 15 is provided with an impact unit for impacting the sliding block 14, the impact unit includes an L-shaped seat 19 fixedly connected to the side wall of the U-shaped seat 15, the inner side of the L-shaped seat 19 is slidably connected to a sliding rod 31, one end of the sliding rod 31 passes through the outside of the L-shaped seat 19 and is fixedly connected to an impact block 20, and the impact block 20 abuts against the outer wall of the sliding block 14, a connecting spring 32 is installed between the L-shaped seat 19 and the impact block 20, the impact unit also includes a U-shaped frame 29 fixedly connected to the other end of the sliding rod 31, the inner side of the U-shaped frame 29 is rotatably connected to a roller 30, the outer wall of the connecting column 21 is fixedly connected to a fixing ring 25, the outer side of the fixing ring 25 is fixedly connected to a plurality of surrounding triangular blocks 28, and the roller 30 abuts against the triangular block 28; When the connecting column 21 rotates, it drives the fixing ring 25 to rotate as well. When the roller 30 moves from the lowest point of the triangular block 28 to the highest point, the impact block 20 gradually moves away from the sliding block 14 from the side of the sliding block 14. When the roller 30 separates from the triangular block 28, the connecting spring 32 drives the impact block 20 to reset, so that the impact block 20 hits the sliding block 14, so that the baffle plate 11 and the material-dispensing block 23 resonate with the contacting molten metal pool. After the vibration is transmitted to the contacting molten metal pool, the surface tension of the molten pool can be destroyed, so that the internal bubbles can escape and the welding defects such as pores can be reduced. The vibration generated by the resonance can accelerate the convection of the molten pool metal, so that the alloy elements are mixed more evenly. At the same time, the auxiliary material-dispensing block 23 pushes the molten pool metal to flow to the edge of the weld, further optimizing the metal distribution and improving the density and mechanical properties of the weld.
[0019] See also Figures 5 to 9 The jet cleaning assembly includes a blocking frame 13 and a jet bucket 12 fixedly connected to the bottom of another inclined plate 10. An jet groove 34 is opened on the inner side of the jet bucket 12. The air inlet of the jet groove 34 is fixedly connected to a connecting pipe 18. The bottom of the connecting plate 8 is fixedly connected to a suspension seat 16. The top of the suspension seat 16 is installed with an air pump 33, and the output end of the air pump 33 is fixedly connected to the connecting pipe 18. The ejected high-pressure gas is an inert gas. The air inlet of the air pump 33 is connected to the inert gas tank. The blocking frame 13 is also made of metal material and has high-temperature resistance. During the heating of the inclined plate 10, the blocking frame 13 is also heated by heat conduction. The air injection groove 34 is set at the edge of the welding part of the laser welding head 3 and does not contact the welding part. When the molten molten pool metal generated at the welding part of the laser welding head 3 flows to both sides, when the molten molten pool metal flows to the unwelded part, the air pump 33 delivers high-pressure gas to the inside of the air injection groove 34, so that the high-pressure gas is ejected, which will overflow the molten pool that has not yet solidified in the unwelded part. The metal is blown to the edge of the weld and blocked by the blocking frame 13, preventing the molten pool metal from being blown too far and reducing the complexity of subsequent grinding. At the same time, through the above operation, the molten pool metal is blown away when it flows to the unwelded area and has not yet solidified, forming an "air curtain barrier" at the edge of the weld, which generates a lateral thrust on the molten pool metal flowing toward the unwelded area, preventing the molten pool metal from overflowing to the surface of the base material in the unwelded area, and avoiding the formation of metal nodules or adhesion spots. The combination of the blocking frame 13 and the air pump 33 realizes the refined control of the flow of the molten pool metal through the synergistic effect of "air curtain blocking + heat conduction anti-solidification + physical guidance", which can not only improve the weld quality and forming accuracy.
