Description

Technical Field

[0001] The invention relates to the field of heat transfer plates, and in particular to a production process and device for a multi-point laser welding self-cleaning heat transfer plate. Background Art

[0002] The existing heat transfer plate production process generally involves welding two metal plates together and injecting fluid or gas into the inside to make it swell and form a cavity inside; However, after the cooler manufactured by the above manufacturing method is manufactured, it is also necessary to test the sealing of the welding joints of the two metal plates forming the "cavity" to remove those that do not meet the requirements to ensure quality. The existing testing method usually places the heat transfer plate upright in a pool filled with a certain amount of liquid. After a period of time, observe whether there are bubbles on the side of the heat transfer plate placed in the liquid. If there are bubbles, it means that it is not completely sealed, and if not, it means that it is completely sealed. The four sides of the heat transfer plate need to be immersed for testing, so this requires additional manpower, material resources and time for testing, which is time-consuming and labor-intensive, prolongs the delivery time, and reduces production efficiency. If the bubbles are small, they are not easy to be found, resulting in misjudgment.

[0035] Next, prepare for positioning the two spot-welded and rolled metal plates: first push the limiting rod 332 and the cap 333 to fit into the limiting teeth 3311, rotate the limiting rod 332 to drive the adjusting rod 32, the positioning plate 34 and the stop plate 341 to rotate, and the positioning plate 34 rotates to face the support frame 21 (such as Fig.15 The limiting rod 332 is pushed to disengage from the fixing rod 31 and get stuck with the limiting tooth 3311 to prevent the limiting rod 332 from driving the adjusting rod 32 to rotate, and to prevent the positioning plate 34 and the stop plate 341 from rotating, resulting in inaccurate positioning. At this time, the inner sides of the positioning plate 34 and the stop plate 341 are flush with the outer sides of the limiting rod 221 and the outer sides of the step 1 211, which are used to position the metal plate placed thereon later; the worker adjusts the detection device 10 to the specified position on the workbench of the hydraulic press 30, so that a pair of pressure plates 20 are opposite to the step 1 211 and the limiting rod 221, so that the rear pressure plate 20 can move downward and press on the peripheral area A.

[0036] At this time, the worker starts to push in a pair of welded metal plates that block either the outlet or the inlet from one side. First, a pair of relative fixing rods 31 allow the pair of metal plates to move accurately on a pair of steps 211 until they move between a pair of positioning plates 34, and continue to move until the end of the metal plate presses against the stop plate 341. At this time, the outer side of the metal plate is in contact with the inner side of the positioning plate 34 and the stop plate 341, that is, the peripheral area A of the metal plate is located on the step 211 and the limiting rod 221, and the limiting rod 332 is pushed to fit with the cap 333, and then the limiting rod 332 is rotated in the opposite direction. The limiting rod 332 drives the adjusting rod 32, the positioning plate 34 and the stop plate 341 to rotate in the opposite direction until the positioning plate 34 and the stop plate 341 are located on the upper side of the adjusting rod 32, and the limiting rod 332 is pushed to fit with the fixing rod 31 to prevent the limiting rod 332 from rotating and affecting the subsequent fit between the display cloth 11 and the metal plate.

[0037] Closing the detection device 10 is performed in the opposite manner to the process of adjusting the detection device 10 to the open state: the worker pushes the plate 62 on either side to rotate it to be perpendicular to the support plate 22, and again drives the assembly rod 61 to move away from the display cloth 11 through the push plate 62, and the assembly rod 61 drives the corresponding driving rod 1 511 to move, and drives the driving rod 1 511 on the other side to move through the rotating shaft 1 512, so that the pair of rotating rods 44 rotate in the opposite direction, driving the transmission belt 42 to rotate, the support member 431 to rotate, the fixing block 432 and the clamping member 12 to rotate, and the clamping member 12 drives the display cloth 11 to move toward Rotate in the direction of the limit rod 221 until the display cloth 11 is relatively fitted with the side of the metal plate. Since the display cloth 11 is made of elastic material, it can be relatively fitted with the side of the metal plate. Similarly, the worker drives the reversing rod 531 to move in the direction away from the display cloth 11 through the driving plate 63, and the reversing rod 531 drives the reversing shaft 532 to rotate, driving the corresponding driving rod 2 521 to move along the length direction of the support plate 22, driving the rotating shaft 2 522 to drive the other side driving rod 2 521 to move, and the driving rod 2 521 drives the rotating rod 44 to rotate until the display cloth 11 is in contact with the side of the metal plate.

[0038] The crossbeam moves downward, and the pressure plate 20 presses on the peripheral area A of the metal plate to fix the metal plate to prevent it from moving during swelling. Then, a high-pressure fluid is injected into a pair of metal plates through the display cloth 11 to swell the plates, and the color of the display cloth 11 is observed at the same time. If the color of the display cloth 11 becomes darker, it means that the fluid flows out from the side of the metal plate corresponding to the deeper part of the display cloth 11. If the color of the display cloth 11 does not change, it means that the sealing is fine.

[0039] For a metal plate with good sealing, it becomes a heat transfer plate after the expansion is completed. The detection device 10 is opened and the heat transfer plate is pulled out.

[0040] For the metal plate with fluid leakage, the detection device 10 is opened, the metal plate is taken out for subsequent processing, and then the detection device 10 is taken out and a new display cloth 11 is replaced; specifically, the worker first removes the upper side of the display cloth 11 from the clamping piece 12, and then lifts up the lifting rod 45 on the same side as the display cloth 11 to be replaced, driving the corresponding multiple flipping structures 4 to move synchronously, and the lifting rod 45 drives the limiting plate 412 to move upward until the limiting plate 412 is disengaged from the limiting groove 421, and then pulls the lifting rod 45 toward the outside of the support plate 22 or the support frame 21, and the lifting rod 45 drives the overall flipping structure 4, the splint 1 23 or the splint 24, the display cloth 11 and the clamping piece 12 to move together until the splint 1 23 or the splint 24 is pulled away from the corresponding step 1 211 and the limiting rod 221, The new display cloth 11 is clamped on the clamping plate 1 23 or the clamping plate 24, and then the lifting rod 45 is lowered to open the clamping plate 1 23 or the clamping plate 24, and the lower side of the new display cloth 11 is placed between the clamping plate 1 23 and the step 212 or between the clamping plate 24 and the supporting plate 22 and fixed; the worker lifts the lifting rod 45 again, driving the overall flipping structure 4, the clamping plate 1 23 or the clamping plate 24, the display cloth 11 and the clamping member 12 to move in the opposite direction until the connecting plate 411 is in contact with the clamping plate 1 23 or the clamping plate 24, and then the lifting rod 45 is dropped, and the lifting rod 45 drives the limiting plate 412 to descend, and the limiting plate 412 descends into the limiting groove 421, and the upper side of the display cloth 11 is placed between the bottom clamp 121 and the top clamp 122 and fixed, and the replacement of the new display cloth 11 is completed; the sealing of the side of the metal plate can be re-tested.
