Description

Technical Field

[0001] This invention relates to the field of weld cooling treatment technology, and more specifically to a metal surface weld treatment device. Background Technology

[0002] A weld is a seam formed by melting and connecting the welding rod and the metal at the joint using the high temperature of a welding heat source. After the weld metal cools, the two welded parts are joined into a whole. Welds are typically used on metals, including metal plates. After the weld is formed, it needs to be cooled. Currently, the cooling method is mainly through natural air drying, which is a long process, inefficient, and not suitable for batch operations.

[0003] To address the aforementioned issues, Chinese Patent No. CN212734732U discloses a rapid cooling device for welding metal sheets. The device includes a base plate with casters mounted at each of its four corners. Support columns are welded to the top of each of the four corners of the base plate, and a frame is connected to the top of each support column. Stainless steel rollers are evenly distributed on the inner walls of both sides of the frame via bearings. Vertical columns are welded to the top of each of the four corners of the frame. A top plate is bolted to the top of the four vertical columns, and a spring-loaded telescopic rod is slidably connected to the bottom of the top plate. A nozzle is connected to the bottom of the spring-loaded telescopic rod via a ball-head hinge, and a spiral water inlet pipe is connected to the water inlet of the nozzle. A water tank is located on the top of the base plate. This cooling device directly cools the weld seam with water sprayed from the nozzle, effectively improving work efficiency.

[0004] The above-mentioned cooling device has the following problems in actual use: When metal plates are placed on stainless steel rollers and water is sprayed from nozzles to cool the weld seams, only the weld seams of a single metal plate can be cooled at a time. This cooling method is inefficient for cooling the weld seams of a batch of metal plates. If multiple metal plates are stacked on stainless steel rollers, the water sprayed from the nozzles can only cool the weld seams of the topmost metal plate, while the weld seams of the other metal plates cannot be cooled. Summary of the Invention

[0005] The present invention aims to provide a metal surface weld treatment device to solve the problem that existing cooling devices can only cool a single metal plate at a time, resulting in low cooling efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal surface weld treatment device, comprising a cooling box, a side opening on the side wall of the cooling box, and a door panel rotatably connected to the side opening; a plurality of rotating shafts rotatably connected to the bottom of the cooling box, and a limiting mechanism for limiting the metal plate on the rotating shafts; a horizontal pipe and a vertical pipe are provided inside the cooling box, the horizontal pipe and the vertical pipe are connected, and an air duct is connected to the horizontal pipe; a pipe is connected to the horizontal pipe, and a flexible hose is connected to the pipe, the end of the flexible hose away from the pipe extending into the horizontal pipe, and a plurality of first air holes are provided at the bottom of the pipe, the first air holes being arranged towards the limiting mechanism; a plurality of second air holes are provided on the side wall of the vertical pipe, the second air holes being arranged towards the limiting mechanism; and further comprising a drive mechanism for simultaneously driving multiple rotating shafts to reciprocate, and a guide mechanism for alternately introducing gas from the air duct into the flexible hose and the vertical pipe respectively.

[0007] Furthermore, the guiding mechanism includes a movable block, a partition fixed inside a horizontal pipe, and an air duct located above the partition. The partition has a first through hole and a second through hole vertically arranged. A flexible hose is fixed to the bottom of the partition, communicating with the first through hole and the second through hole communicating with the vertical pipe. The partition has a chamber communicating with both the first and second through holes. A guide plate is located within the chamber, capable of reciprocating laterally within the chamber, and rubbing against the inner wall of the chamber. The guide plate has a first guide hole and a second guide hole vertically arranged. The first guide hole is offset from the first through hole, and the second guide hole communicates with the second through hole. The first guide hole can communicate with the first through hole. The bottom of the partition has a bottom groove communicating with the chamber. The movable block is laterally slidably connected to the bottom groove, and the movable block is fixed to the bottom of the guide plate. The mechanism also includes a power unit for driving the movable block to reciprocate laterally.

[0008] Furthermore, the power unit includes a power block that is vertically slidably connected to the partition, a round shaft that is rotatably connected to the transverse tube, and a power component for driving the power block to reciprocate vertically. The power block is provided with a rack, the round shaft is located below the partition, and a gear and a cylindrical cam are coaxially connected on the round shaft. The rack meshes with the gear. The cylindrical cam is provided with a curved groove, and the end of the movable block away from the guide plate is slidably connected to the curved groove.

[0009] Furthermore, the rotating shaft extends into the transverse tube and is rotatably connected to the transverse tube; the driving mechanism includes a worm gear coaxially connected to the round shaft and a worm wheel coaxially connected to the round shaft, the worm gear is rotatably connected to the transverse tube, and the worm wheel meshes with the worm gear.

[0010] Furthermore, the rotating shaft extends into the transverse tube and is rotatably connected to the transverse tube; the driving mechanism includes a worm gear coaxially connected to the round shaft and a worm wheel coaxially connected to the round shaft, the worm gear is rotatably connected to the transverse tube, and the worm wheel meshes with the worm gear.

[0011] Furthermore, the bottom of the horizontal pipe is provided with a wall groove, and a wall block is slidably connected in the wall groove, with the wall block being fixedly connected to the pipe.

[0012] Furthermore, the width of the first guide hole is smaller than the width of the first through hole.

[0013] Furthermore, a support ring is provided on the side wall of the horizontal pipe, and the support ring is sleeved on the outer wall of the air duct; a vertical hole is provided at the bottom of the support ring, and a pressing block is slidably connected in the vertical hole, and a spring is provided between the pressing block and the support ring; a cam body is coaxially connected to the worm gear, and the cam body abuts against the pressing block.

[0014] Furthermore, an adjusting block is slidably connected to the vertical pipe, and the adjusting block has a vertical adjusting hole, the width of which is smaller than the internal width of the vertical pipe; the adjusting block is fixedly connected to the pipe.

[0015] Furthermore, the width of the second guide hole is smaller than the width of the second through hole.

[0016] The principles and advantages of this scheme are: 1. This solution uses a limiting mechanism on each rotating shaft to limit the metal plates, thereby limiting multiple metal plates. Air can alternately enter the flexible hose and the vertical pipe. When air enters the flexible hose, it acts on the welds of multiple metal plates simultaneously in the vertical direction through the pipe and the first air hole. When air enters the vertical pipe, it acts on the welds of multiple metal plates simultaneously in the horizontal direction through the second air hole. Compared with the existing cooling methods, this solution can act on multiple metal plates simultaneously in the horizontal and vertical directions, that is, it can cool multiple welds of multiple metal plates at a time, resulting in higher work efficiency.

[0017] 2. During the reciprocating rotation of the cylindrical cam in this scheme, the cylindrical cam drives the pipe to reciprocate laterally through the curved groove and slider. The pipe drives multiple first air holes to move synchronously, thereby expanding the range of air ejected from the first air holes in the horizontal direction. This allows more of the metal plate to be affected by the air, thereby promoting the cooling of welds at different locations on the metal plate and improving work efficiency.

[0018] 3. During the slow reciprocating rotation of the cylindrical cam in this scheme, the cylindrical shaft rotates synchronously and slowly. The cylindrical shaft drives the worm gear to rotate slowly, and the worm gear meshes with the worm wheel to drive the rotating shaft to rotate slowly. The rotating shaft drives the metal plate inside the mesh frame to rotate slowly, so that the weld seams at different positions on both sides of the metal plate can be affected by the air sprayed from the first and second air holes, expanding the range of action on the metal plate, thereby promoting the cooling treatment of the weld seams at different positions on the metal plate and improving work efficiency.

[0019] 4. In this scheme, when the second through hole and the second guide hole are misaligned, the first through hole and the first guide hole are connected. During the rotation of the circular shaft, the circular shaft drives the cam body to rotate through the worm gear, causing the protrusion of the cam body to push the extrusion block upward. The extrusion block extrudes and deforms the air duct, making the diameter of the air duct smaller. This allows the air passing through the air duct to be accelerated, making the air jet from the first air hole through the first through hole, the first guide hole, the hose, and the pipe farther. This expands the range of air jet from the first air hole in the vertical direction, allowing more of the metal plate to be affected by the air, thereby promoting the cooling treatment of welds at different positions on the metal plate and improving work efficiency.

[0020] 5. In this design, when the second through hole is connected to the second guide hole, the first through hole is offset from the first guide hole. During the reverse rotation of the cylindrical shaft, the cylindrical cam drives the slider to move laterally through the curved groove. The slider drives the pipe to move to the left, and the pipe drives the adjusting block to move to the left, minimizing the diameter of the hole connecting the adjusting hole to the inside of the vertical pipe. This accelerates the airflow through the adjusting hole, allowing the airflow from the second air hole to travel further. This expands the horizontal range of the airflow from the second air hole, enabling more of the metal plate to be affected by the airflow. This promotes cooling of the welds at different locations on the metal plate and improves work efficiency.

[0021] 6. During the lateral reciprocating motion of the pipeline in this scheme, the pipeline drives the wall block to reciprocate laterally within the wall groove, thereby providing support and guidance for the pipeline and improving the stability of the pipeline's lateral movement. Furthermore, during the lateral reciprocating motion of the pipeline, the pipeline also drives the adjusting block to reciprocate laterally on the vertical pipe, thereby providing support and guidance for the pipeline and improving the stability of the pipeline's lateral movement.

[0022] 7. The width of the first guide hole in this design is smaller than the width of the first through hole, which can extend the communication time between the first guide hole and the first through hole, thereby extending the duration of the air ejected from the first air hole, that is, extending the duration of cooling the metal plate in the vertical direction, and improving the cooling efficiency.

[0023] 8. The width of the second guide hole in this design is smaller than the width of the second through hole, which can extend the communication time between the second guide hole and the second through hole, thereby extending the duration of the air ejected from the second air hole, that is, extending the duration of cooling the metal plate in the horizontal direction, and improving the cooling efficiency.

[0027] Three rotating shafts 20 are rotatably connected to the bottom of the cooling box 10. Each rotating shaft 20 is equipped with a limiting mechanism for limiting the metal plate. The limiting mechanism includes a sleeve 21 and a mesh frame 22. The sleeve 21 is fitted onto the outer wall of the rotating shaft 20, i.e., the sleeve 21 is fixedly connected to the rotating shaft 20. The mesh frame 22 is fixedly connected to the sleeve 21. An opening is opened on the side wall of the mesh frame 22, and the metal plate can be placed into the mesh frame 22 through the opening. Threaded seats 23 are fixedly connected to both sides of the opening on the mesh frame 22. Existing bolts 24 are used to thread the two threaded seats 23. After the metal plate is placed into the mesh frame 22 through the opening, the existing bolts 24 are used to thread the two threaded seats 23, thereby limiting the metal plate and preventing it from falling out of the mesh frame 22.

[0028] A horizontal pipe 30 and a vertical pipe 31 are fixedly connected inside the cooling box 10. The bottom of the horizontal pipe 30 is connected to the top of the vertical pipe 31. A duct 32, which is a flexible conduit, is connected to the horizontal pipe 30. An existing electric fan is used to generate air, which is introduced into the duct. The air is mainly used to cool the weld seams of the metal plate. A pipe 33 is connected to the horizontal pipe 30. A flexible hose 34 is connected to the pipe 33. The end of the flexible hose 34 away from the pipe 33 extends into the horizontal pipe 30 and is sealed to the horizontal pipe 30. Several first air holes 35 are opened at the bottom of the pipe 33. The first air holes 35 are arranged vertically and face the mesh frame 22. Several second air holes 36 are opened on the side wall of the vertical pipe 31. The second air holes 36 are arranged horizontally and face the mesh frame 22.

[0029] It also includes a guiding mechanism for alternately introducing gas from the duct 32 into the hose 34 and the vertical pipe 31, respectively. The guiding mechanism includes a movable block 40 and a partition 41 fixedly connected to the horizontal pipe 30. The duct 32 is located above the partition 41. The partition 41 divides the horizontal pipe 30 into upper and lower spaces. The partition 41 has a first through hole 42 and a second through hole 43 vertically opened on it. The end of the hose 34 away from the pipe 33 is fixedly connected to the bottom of the partition 41. The hose 34 communicates with the first through hole 42 and the second through hole 43 communicates with the vertical pipe 31. A chamber 44 is horizontally opened inside the partition 41. The chamber 44 communicates with the first through hole 42 and the second through hole 43. Two through holes 43 are connected; a guide plate 45 is provided in the chamber 44, and the guide plate 45 can move laterally back and forth in the chamber 44. The guide plate 45 is in frictional contact with the inner wall of the chamber 44; a first guide hole 46 and a second guide hole 47 are vertically opened on the guide plate 45. The first guide hole 46 is offset from the first through hole 42, and the second guide hole 47 is connected to the second through hole 43. The first guide hole 46 can be connected to the first through hole 42; a bottom groove 48 is opened laterally at the bottom of the partition plate 41. The bottom groove 48 is connected to the chamber 44. The movable block 40 is laterally slidably connected to the bottom groove 48. The movable block 40 is fixedly connected to the bottom of the guide plate 45. A fixing plate 49 is vertically fixed to the bottom of the partition 41. The round shaft 51 is rotatably connected to the fixing plate 49. The fixing plate 49 divides the space below the partition 41 into two inner chambers, left and right. The first through hole 42, the second through hole 43 and the hose 34 are all located on the left side of the fixing plate 49. The end of the vertical pipe 31 that connects to the horizontal pipe 30 is located on the left side of the fixing plate 49. When the second through hole 43 is connected to the second guide hole 47, the setting of the fixing plate 49 can promote the air to directly enter the vertical pipe 31 through the second through hole 43 and the second guide hole 47.

[0030] It also includes a power unit for driving the movable block 40 to reciprocate laterally. The power unit includes a power block 50 slidably connected vertically to the partition plate 41, a round shaft 51 rotatably connected to the transverse tube 30, and a power component for driving the power block 50 to reciprocate vertically. A rack 52 is fixedly connected to the side wall of the power block 50. The round shaft 51 is located below the partition plate 41. A gear 53 and a cylindrical cam 54 are coaxially connected to the round shaft 51. The rack 52 meshes with the gear 53. A curved groove is opened on the cylindrical cam 54. The end of the movable block 40 away from the guide plate 45 is slidably connected to the curved groove. The power component is a cylinder 55, which is fixedly connected inside the cooling box 10. The power block 50 is slidably connected vertically to the transverse tube 30, and the output shaft of the cylinder 55 is fixedly connected to the power block 50.

[0031] The rotating shaft 20 extends into the transverse tube 30 and is rotatably connected to the transverse tube 30; it also includes a drive mechanism for simultaneously driving the three rotating shafts 20 to reciprocate, the drive mechanism includes a worm 60 coaxially connected to the round shaft 51 and a worm wheel 61 coaxially connected to the round shaft 51, the worm 60 is rotatably connected to the transverse tube 30, and the worm wheel 61 meshes with the worm 60.

[0032] A transverse groove 70 is formed at the bottom of the transverse tube 30. A slider 71 is slidably connected within the groove 70. One end of the slider 71 is fixed to the tube 33, and the other end is slidably connected to the curved groove. That is, the movable block 40 is located above the cylindrical cam 54, and the slider 71 is located below the cylindrical cam 54, so that the movement direction of the slider 71 is opposite to the movement direction of the movable block 40. The flexible hose 34 has sufficient length to accommodate the transverse reciprocating motion of the tube 33. Three auxiliary holes 331 are integrally formed on the tube 33. The auxiliary holes 331 are not connected to the interior of the tube 33. During the transverse reciprocating motion of the tube 33, the rotating shaft 20 can move relatively laterally within the auxiliary holes 331. That is, the transverse reciprocating motion of the tube 33 and the rotation of the rotating shaft 20 do not affect each other. A wall groove 72 is formed at the bottom of the transverse tube 30. A wall block 73 is slidably connected within the wall groove 72 and is fixed to the tube 33.

[0033] A support ring 80 is fixedly connected to the side wall of the transverse pipe 30, and the support ring 80 is sleeved on the outer wall of the air duct 32. A vertical hole is opened at the bottom of the support ring 80, and a pressing block 81 is slidably connected inside the vertical hole. A spring 82 is fixedly connected between the pressing block 81 and the support ring 80, that is, the spring 82 is sleeved outside the pressing block 81. The upper end of the spring 82 is fixedly connected to the bottom of the support ring 80, and the lower end of the spring 82 is fixedly connected to the outer wall of the pressing block. The upper end of the pressing block 81 abuts against the air duct 32. A cam body 83 is coaxially connected to the worm gear 60, and the cam body 83 abuts against the lower end of the pressing block 81. In the initial state, the protrusion of the cam body 83 does not abut against the lower end of the pressing block 81, that is, the protrusion of the cam body 83 is away from the protrusion of the cam body 83, the protrusion of the cam body 83 faces downward, and at this time the spring 82 is in its natural state and is not compressed.

[0034] An adjusting block 90 is slidably connected to the vertical pipe 31. The adjusting block 90 can cover the interior of the vertical pipe 31. An adjusting hole 91 is vertically opened on the adjusting block 90. ​​The width of the adjusting hole 91 is smaller than the interior width of the vertical pipe 31. The adjusting block 90 is fixedly connected to the pipe 33.

[0035] The specific implementation process is as follows: In use, the three metal plates are placed one by one into the three mesh frames 22. Each mesh frame 22 is connected to the two threaded seats 23 on the mesh frame 22 by the existing bolts 24, so as to limit the metal plates and prevent the metal plates from falling out of the mesh frame 22. Rotate the door panel 12 so that the door panel 12 blocks the side opening 11. Use the existing electric fan to introduce the air into the air duct 32, and then the air enters the horizontal pipe 30.

[0036] When cylinder 55 is activated, the output shaft of cylinder 55 drives power block 50 to slowly reciprocate up and down. Power block 50 drives rack 52 to slowly reciprocate up and down. When rack 52 moves slowly downward, rack 52 meshes with gear 53, driving round shaft 51 to slowly rotate. Round shaft 51 drives cylindrical cam 54 to slowly rotate. Cylindrical cam 54 drives guide plate 45 to slowly move to the left through curved groove and movable block 40, causing the second through hole 43 to be misaligned with the second guide hole, and the first through hole 42 to communicate with the first guide hole. This prevents air from entering vertical pipe 31 through the second through hole 43 and the second guide hole, allowing air to enter pipe 33 through the first through hole 42, the first guide hole, and hose 34. When rack 52 moves slowly upward... During the movement, the rack 52 meshes with the gear 53, causing the round shaft 51 to rotate slowly in the opposite direction. The round shaft 51 causes the cylindrical cam 54 to rotate slowly in the opposite direction. The cylindrical cam 54 drives the guide plate 45 to move slowly to the right through the curved groove and the movable block 40, so that the second through hole 43 communicates with the second guide hole, and the first through hole 42 is offset from the first guide hole, preventing the air from entering the pipe 33 through the first through hole 42, the first guide hole, and the hose 34. Instead, the air enters the vertical pipe 31 through the second through hole 43 and the second guide hole. Therefore, during the slow up-and-down reciprocating movement of the rack 52, the cylindrical cam 54 slowly reciprocates, causing the guide plate to move slowly in the lateral direction. The air can alternately enter the pipe 33 and the vertical pipe 31 respectively.

[0037] When air enters the vertical pipe 31, it is ejected through the second air hole 36 and acts horizontally on multiple metal plates simultaneously, thereby cooling the plates. When air enters the pipe 33, it is ejected through the first air hole 35 and acts vertically on multiple metal plates simultaneously, also cooling them. Therefore, this solution can simultaneously cool the weld seams on multiple metal plates both horizontally and vertically. For cooling batches of metal plates, this solution offers higher cooling efficiency.

[0038] During the slow reciprocating rotation of the cylindrical cam 54, the cylindrical cam 54 drives the pipe 33 to move slowly in the horizontal direction through the curved groove and the slider 71. The pipe 33 drives multiple first air holes 35 to move slowly in sync. This can expand the range of air ejected from the first air holes 35 in the horizontal direction, that is, expand the range of air flow in the horizontal direction, so that more areas of the metal plate can be affected by the wind, thereby promoting the cooling treatment of welds at different positions on the metal plate and improving work efficiency.

[0039] During the slow reciprocating rotation of the cylindrical cam 54, the circular shaft 51 reciprocates synchronously and slowly. The circular shaft 51 drives the worm gear 60 to reciprocate slowly. The worm gear 60 meshes with the worm wheel 61, driving the rotating shaft 20 to reciprocate slowly. The rotating shaft 20 drives the metal plate inside the mesh frame 22 to reciprocate slowly. During the slow rotation of the metal plate, different positions of the metal plate are affected by the air sprayed from the first air hole 35 and the second air hole 36, expanding the range of action on the metal plate. This allows more of the metal plate to be affected by the air, thereby promoting the cooling treatment of the weld seams at different positions on the metal plate and improving work efficiency.

[0040] As rack 52 moves slowly downwards, gear 53 meshes with gear 53, causing shaft 51 to rotate slowly. Shaft 51 then rotates cylindrical cam 54 slowly. Cylindrical cam 54, through a curved groove, causes movable block 40 and slider 71 to move slowly laterally. This causes movable block 40 to move guide plate 45 slowly to the left, causing the second through hole 43 to be offset from the second guide hole 47, and the first through hole 42 to communicate with the first guide hole 46. Simultaneously, slider 71 causes pipe 33 to move slowly to the right, and pipe 33 causes adjusting block 90 to move slowly to the right, maximizing the diameter of the hole connecting adjusting hole 91 to the interior of vertical pipe 31. During the slow rotation of shaft 51, shaft 51 drives worm 60 to rotate slowly, and worm 60 drives cam body 83 to rotate slowly. The slow rotation causes the protrusion of the cam body 83 to push the extrusion block 81 upward, bringing the two ends of the spring 82 closer together, thus compressing the spring 82. During the upward movement of the extrusion block 81, the extrusion block 81 deforms the air duct 32, reducing the diameter of the air duct 32. This accelerates the air passing through the air duct 32, allowing the air to travel a longer distance from the first air hole 35 through the first through hole 42, the first guide hole, the hose 34, and the pipe 33. This expands the effective range of the air ejected from the first air hole 35 in the vertical direction, increasing the airflow range and allowing more of the metal plate to be affected by the air. This promotes cooling of the weld seams at different locations on the metal plate, improving work efficiency.

[0041] During the slow upward movement of rack 52, gear 53 meshes with gear 53, causing the circular shaft 51 to rotate slowly in the opposite direction. The circular shaft 51 then causes the cylindrical cam 54 to rotate slowly in the opposite direction. The cylindrical cam 54, through the curved groove, causes the movable block 40 and slider 71 to move slowly laterally, causing the movable block 40 to drive the guide plate 45 to move slowly to the right. The second through hole 43 communicates with the second guide hole 47, while the first through hole 42 and the first guide hole 46 are offset. At the same time, the slider 71 causes the pipe 33 to move slowly to the left, and the pipe 33 causes the adjusting block 90 to move slowly to the left, minimizing the diameter of the hole connecting the adjusting hole 91 to the inside of the vertical pipe 31. During the slow reverse rotation of the circular shaft 51, the circular shaft 51 drives the worm gear 60 to rotate slowly in the opposite direction, and the worm gear 60 drives the cam body 83 to rotate slowly in the opposite direction. This causes the protrusion of the cam body 83 to move away from the extrusion block 81, meaning the extrusion of the cam body 83 on the extrusion block 81 disappears. This causes the extrusion block 81 to move in the opposite direction under the spring 82, and the air duct 32 returns to its original state. Furthermore, the air enters the vertical pipe 31 through the second through hole 43 and the second guide hole. Since the diameter of the adjusting hole 91 communicating with the interior of the vertical pipe 31 is the smallest, the air passing through the adjusting hole 91 can be accelerated, allowing the air ejected from the second air hole 36 to travel a longer distance. This expands the horizontal range of the air ejected from the second air hole 36, increasing the airflow range and allowing more of the metal plate to be affected by the airflow. This, in turn, promotes cooling of the weld seams at different locations on the metal plate, improving work efficiency.

[0042] During the lateral reciprocating motion of pipe 33, pipe 33 drives wall block 73 to reciprocate laterally within wall groove 72, thereby providing support and guidance for pipe 33 and improving the stability of lateral movement of pipe 33. Furthermore, during the lateral reciprocating motion of pipe 33, pipe 33 also drives adjusting block 90 to reciprocate laterally on vertical pipe 31, thereby providing support and guidance for pipe 33 and improving the stability of lateral movement of pipe 33.

[0043] In this embodiment, the width of the first guide hole is smaller than the width of the first through hole 42, which can prolong the communication time between the first guide hole and the first through hole 42, thereby prolonging the duration of the air ejected from the first air hole 35, that is, prolonging the duration of cooling the metal plate in the vertical direction, and improving the cooling efficiency.

[0044] In this embodiment, the width of the second guide hole is smaller than the width of the second through hole 43, which can prolong the communication time between the second guide hole and the second through hole 43, thereby prolonging the duration of the air ejected from the second air hole 36, that is, prolonging the cooling time of the metal plate in the horizontal direction, and improving the cooling efficiency.

[0045] In this embodiment, three water spray pipes 13 are connected to the rear side wall of the cooling box 10. The water spray pipes 13 are positioned corresponding to the mesh frame 22. Each water spray pipe 13 is fixed with a nozzle (not shown in the figure). The nozzle is located inside the cooling box 10 and faces the mesh frame 22. A water outlet pipe 14 is connected to the bottom of the cooling box 10. Water with impact force is introduced into the water spray pipes 13. The water sprays out from the nozzle and acts on the mesh frame 22, which can cool the weld seam on the metal plate. The water falls to the bottom of the cooling box 10 and is finally discharged from the water outlet pipe 14. Depending on the usage requirements, either air cooling or water cooling can be used to cool the weld seam of the metal plate. Alternatively, air cooling and water cooling can be used simultaneously or delayed to cool the weld seam of the metal plate.
