Description

Technical Field

[0001] This invention relates to the field of welding processing technology, and specifically to an integrated welding device for the production of cold-rolled pallet plates. Background Technology

[0002] Cold plate trays, also known as cooling water plates, are components that play a crucial role in heat dissipation during industrial production and equipment operation. They are typically made of metallic materials such as aluminum alloys and copper alloys, which possess excellent thermal conductivity, enabling them to quickly conduct and dissipate heat from the heat source, ensuring stable operation of equipment within a suitable temperature environment.

[0003] With the continuous development of industrial technology, the performance requirements for cold-rolled pallet sheets are also increasing. Welding is one of the key steps in the manufacturing process of cold-rolled pallet sheets, as it directly affects the overall performance and quality of the sheets.

[0004] Friction welding, as an advanced solid-state welding technology, has unique advantages. It uses the heat generated by friction to bring the weld joint to a plastic state, and then achieves connection under the action of upsetting force. The entire process does not require the addition of filler material, and the heat-affected zone is small, which can effectively avoid the deformation problems caused by traditional welding methods.

Two protective covers are provided on the welding head, and the two protective covers are in contact with each other. It should be noted that in this invention, the two protective covers effectively protect the welding head, ensuring its safety and thus guaranteeing the normal operation of the welding process for cooling plates in new energy vehicles. Furthermore, a vacuum cleaner can be activated during welding, absorbing the fumes and sparks generated during welding, preventing environmental pollution and avoiding injury from splashed sparks. This makes it more convenient to use and eliminates safety hazards.

[0006] However, this patent requires manual fixing when loading materials, and the poor alignment affects the efficiency of subsequent welding.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0034] like Figures 1 to 7 As shown, the present invention provides an integrated welding device for producing cold-rolled pallet plates, comprising: a truss 1, a conveyor 2, a processing table 3, a conveying mechanism 4 for transporting cold-rolled pallet plates from the conveyor 2 to the processing table 3, and a welding mechanism 5 for welding the cold-rolled pallet plates.

[0035] The conveying mechanism 4 includes: a screw 41 fixedly mounted on the truss 1; a mounting plate 42 threadedly connected to the screw 41; a clamping plate 43 slidably mounted on the mounting plate 42; a drive assembly for driving the clamping plate 43 to slide horizontally; a motor 45 for driving the screw 41 to rotate; a cylinder 46 fixedly mounted on the clamping plate 43; a push block 47 fixedly connected to the piston rod of the cylinder 46; and clamping blocks 48 rotatably mounted on the push block 47; the clamping blocks 48 are symmetrically arranged in two sets.

[0036] The drive assembly includes: a second motor 441 fixedly mounted on the mounting plate 42, and a rotating wheel 442 rotatably mounted on the mounting plate 42; the output shaft of the second motor 441 and the rotating wheel 442 are provided with a conveyor belt 443, and a clamping plate 43 is fixedly mounted on the conveyor belt 443.

[0037] When welding is required on a cold-rolled steel plate pallet, the operator simply places the cold-rolled steel plate to be processed precisely at the designated position on the conveyor table 2. The conveyor table 2 then starts, smoothly transporting the cold-rolled steel plate towards the processing table 3. Subsequently, drive motor 1 45 starts, driving screw 41 to rotate. Under the threaded transmission of screw 41, mounting plate 42 moves upward along the axis of screw 41. At the same time, drive motor 2 441 starts running, driving conveyor belt 443 to rotate, which in turn drives clamping plate 43 to move horizontally along mounting plate 42, allowing clamping plate 43 to be accurately transported to the area directly above the conveyor frame.

[0038] After the conveyor belt transports the cold plate to the pre-set processing area, the clamping plate 43 gradually approaches the cold plate to be processed under the coordinated drive of motor 45 and motor 441. At this time, the drive cylinder 46 starts to work, the piston rod of the cylinder 46 extends, and pushes the clamping block 48 closer to the cold plate to be welded, until the cold plate is firmly clamped between the two clamping blocks 48.

[0039] Finally, through the coordinated drive of drive motor 45 and motor 441, the clamped and fixed cold plate is precisely moved onto processing table 3. This meticulously designed mechanical structure and automated process effectively reduces manual intervention. Simultaneously, during the switching between processing tables 3, reliable fixation of the cold plate is achieved, significantly reducing errors caused by workpiece misalignment during welding and improving welding accuracy and product quality.

[0040] An auxiliary top plate 49 is provided between the two clamping blocks 48, and the two clamping blocks 48 are respectively hinged to the auxiliary top plate 49 via hinge rods 50. When the cylinder 46 is activated, its piston rod extends and pushes one clamping block 48 toward the other clamping block 48 in a linear motion. Due to the transmission action of the hinge rods 50, the auxiliary top plate 49 hinged between the two clamping blocks 48 will be subjected to a driving force toward the middle area of ​​the two clamping blocks 48. Under the action of this driving force, the auxiliary top plate 49 moves along a specific direction toward the location of the cold plate on the pallet until it is tightly attached to the surface of the cold plate on the pallet and a clamping force is applied.

[0041] At this point, the cold plate on the pallet is reliably clamped and fixed from all four sides by the combined clamping force of the side clamping blocks 48 and the top clamping force of the auxiliary top plate 49. This four-sided clamping method can effectively restrict the degree of freedom of the cold plate in all directions, maximize the positional stability of the cold plate during the welding process, and thus significantly improve the welding accuracy and ensure that the welding quality meets high standards.

[0042] The clamping plate 43 is also provided with a rotating assembly that drives the cold plate of the tray to rotate.

[0043] The rotating assembly includes: a motor 401 fixedly mounted on the clamping plate 43, a rotating rod 402 fixedly connected to the output shaft of the motor 401, and a clamping block 48 fixedly connected to the rotating rod 402;

[0044] When reverse processing of the cold-plate pallet is required, simply start the drive motor 401. The output shaft of motor 401 rotates, driving the rotating rod 402 to rotate around its own axis via a coupling and other transmission components. During the rotation of the rotating rod 402, it simultaneously drives the clamping block 48, which is rigidly connected to it, and the cold-plate pallet clamped and fixed on the clamping block 48, to rotate in space, achieving a precise 180° flip of the cold-plate pallet. This design gives the device the ability to continuously process the cold-plate pallet on both sides, effectively expanding the device's functional application range and improving its versatility and flexibility in different processing scenarios.

[0045] The welding mechanism 5 includes: a mounting frame 51 fixedly mounted on the processing table 3, a motor 42 fixedly mounted on the mounting frame 51, a threaded rod 53 fixedly connected to the output shaft of the motor 42, a sliding plate 54 threadedly connected to the screw 41, and a welding head 55 slidably mounted on the sliding plate 54.

[0046] When the cold plate on the pallet is moved to the position below the welding head 55, the motor 4 52 moves the welding head 55 along the threaded rod 53, and the welding head 55 performs welding on the cold plate on the pallet.

[0047] Friction welding, as an advanced solid-state welding technology, has shown unique and significant advantages in the manufacture of chilled water plates. Because its welding process does not require melting metal, but rather achieves connection by generating heat through friction to bring the contact surfaces to a plastic state, this characteristic greatly reduces the size of the heat-affected zone. This is undoubtedly a boon for chilled water plates, as an excessively large heat-affected zone can easily lead to localized overheating and deformation. However, when performing friction welding, downward pressure needs to be applied to the weldment to ensure the stability of the welding process and the reliability of the weld quality. But this pressure application method can be a double-edged sword in some situations; especially when the chilled water plate has a thin structure or insufficient material rigidity, excessive downward pressure may cause the weldment to bend during the welding process.

[0048] The processing table 3 is also equipped with a lifting assembly; the lifting assembly includes: a sliding groove 561 formed on the processing table 3, a top member 562 slidably installed in the sliding groove 561, and a lead screw 563 rotatably installed in the sliding groove 561; the lead screw 563 is connected to the output shaft of the motor 52 via a belt 564; the top member 562 is threadedly connected to the lead screw 563.

[0049] When motor 52 starts and drives the threaded rod 53 to rotate around its own axis, the lead screw 563 starts to rotate synchronously under the action of the transmitted force through the synchronous transmission mechanism formed by belt 564. It should be noted that the thread pitch of the lead screw 563 and the threaded rod 53 is designed to be the same, and this key design parameter ensures the synchronization and coordination of their movements.

[0050] As motor 52 continuously rotates and drives welding head 55 downward to perform welding operations, lead screw 563, with the same pitch characteristic as threaded rod 53, synchronously drives top member 562 to move linearly. The movement trajectory of top member 562 precisely matches the descent trajectory of welding head 55, ensuring that top member 562 remains stably positioned directly below welding head 55. At this time, top member 562 applies a vertically upward supporting pressure to the cold plate on the pallet placed in the working area, which balances and counteracts the downward pressure applied by welding head 55.

[0051] This design is particularly suitable for situations where the cold plate of the pallet is thin or the material has poor rigidity. It can effectively avoid the uneven stress and bending deformation caused by excessive downward pressure applied by the welding head 55 during the welding process, thereby ensuring the welding quality and the forming accuracy of the workpiece.

[0052] Although friction welding is a solid-state welding method that relies on friction to generate heat and bring materials to a plastic state for connection, some materials may be lost due to friction and compression during welding. This loss is more pronounced when there are small gaps or uneven material thickness at the joint surfaces. Material replenishment can fill these gaps, ensuring that the welded joint is fully filled and improving the welding quality and strength.

[0053] The welding head 55 is equipped with a material replenishment mechanism:

[0054] The feeding mechanism includes: a sleeve 571 sleeved on the outside of the friction welding head 55 body; a material storage chamber 572 and an air outlet chamber 573 are provided inside the sleeve 571; a partition 574 is provided between the material storage chamber 572 and the air outlet chamber 573; a material leakage port 575 is provided on the partition 574; a stop rod 576 is provided at the material leakage port 575; a ring sleeve 577 is fixedly connected to the stop rod 576; the ring sleeve 577 is slidably installed on the outside of the sleeve 571; a pressure rod 578 is fixedly installed on the sleeve 571; a roller 579 is provided on the pressure rod 578; and an air inlet device is connected to the air outlet chamber 573.

[0055] When the welding head 55 needs to perform welding operations on the cold plate of the tray, it should be noted that the slide plate 54 is also equipped with a drive mechanism for driving the welding head 55 to make vertical downward linear motion. The drive mechanism is preferably a cylinder 46. With the stable linear driving force output by the cylinder 46, the downward movement of the welding head 55 can be precisely controlled.

[0056] As the cylinder 46 drives the welding head 55 to move downwards and gradually approach the cold plate of the tray for welding, the ring 577, which is sleeved outside the sleeve shaft 571, will slide upwards in a straight line along the axis of the sleeve shaft 571 due to the reaction force applied by the surface of the cold plate of the tray. As the ring 577 moves upwards, it will simultaneously drive the stop rod 576, which is rigidly connected to it, to move upwards. As the stop rod 576 rises, the discharge port 575, which was originally blocked, is opened and is no longer blocked by the stop rod 576.

[0057] During friction welding, when the welding head 55 contacts the cold plate of the tray and generates frictional heat for welding, the material replenishment mechanism can be automatically triggered to realize the automatic replenishment of welding materials, effectively ensuring the continuity of the welding process and the stability of welding quality.

[0058] The discharge port 575 is funnel-shaped, gradually narrowing from the discharge direction.

[0059] It should be explained in detail that the exhaust chamber 573 of the device is strategically positioned directly below the material storage chamber 572, forming a vertically corresponding structural relationship. When performing friction welding on the cold plate of the pallet using the welding head 55, firstly, the shielding gas source is turned on, and the shielding gas is precisely delivered to the gas chamber through a specific pipeline. The shielding gas accumulates in the gas chamber and forms a stable airflow, which is then evenly sprayed out from the exhaust port of the gas chamber, directly acting on the surface of the cold plate of the pallet being welded. This shielding gas not only effectively removes the large amount of heat generated during the welding process, providing effective cooling for the cold plate of the pallet and preventing changes in material properties or welding deformation due to localized overheating; it also forms a dense gas protective layer in the welding area, isolating oxygen in the air and preventing oxidation of the cold plate of the pallet under high-temperature welding conditions, thereby ensuring welding quality.

[0060] When the baffle 576 moves upward under the action of the aforementioned linkage mechanism, releasing the blockage of the material outlet 575, the channel between the material storage chamber 572 and the air outlet 573 is opened. At this time, the pre-stored replenishment material in the material storage chamber 572 begins to fall under the action of gravity and smoothly enters the air outlet 573. Since there is a stable air pressure continuously provided by the protective air source in the air outlet 573, the replenishment material will be subjected to a uniform force of air pressure after entering the air outlet 573, and thus be sprayed out at high speed from the nozzle of the air outlet 573 in the form of mist or uniform particles, accurately sprayed onto the working area of ​​the welding head 55.

[0061] The aforementioned structure not only ensures uniform spraying of the replenishing material, effectively preventing material jamming caused by accumulation or blockage, and guaranteeing smooth material feeding, but also, by spraying the replenishing material near the welding head (55°), it can promptly fill any tiny gaps or material losses that may occur during welding, further improving the weld density and quality stability. Simultaneously, the entire material feeding process is synchronized with the shielding gas supply and welding operation, requiring no additional manual intervention or complex mechanical movements, significantly improving feeding efficiency and enhancing the automation level and production efficiency of the entire welding equipment.

[0062] Furthermore, by setting up the pressure rod 578, on the one hand, it can press the cold plate of the tray before welding by the welding head 55, improving the stability of the device; on the other hand, when the stop rod 576 connected to the other end of the pressure rod 578 moves along the surface of the cold plate of the tray with the pressure rod 578, the unevenness of the cold plate of the tray causes a small up-and-down movement within the material outlet 575, preventing the replenishing material from clogging the material outlet 575.
