Description

Technical Field

[0001] This invention belongs to the field of automotive radiator core technology, specifically a continuous welding device and welding method for automotive radiator cores. Background Technology

[0002] The radiator core is the core component of a car radiator, usually made of metal, and is responsible for heat dissipation. Its main function is to absorb the heat generated by the engine through flowing coolant and carry the heat away through the air outside the radiator, thereby maintaining the normal operating temperature of the engine. Inside the radiator core, there is a series of coolant channels through which the coolant flows to absorb the heat generated by the engine. The welding equipment is a special device used to produce car radiator cores, and it uses continuous welding technology to weld the various components of the radiator core.

[0003] However, the existing continuous welding device and welding method for automotive radiator cores still have certain drawbacks:

[0004] When welding the core, the component is often placed directly on the bottom of the welding head. However, when the components of the radiator core are covered with dirt and dust, these impurities will affect the fusion of the welding materials, resulting in an unstable weld joint, which in turn affects the performance of the radiator. The temperature of the welding area on the core surface is not stable enough, and the radiator components are prone to deformation and cracking. Therefore, a continuous welding device for automotive radiator cores is designed. Summary of the Invention

[0008] Preferably, a recessed hole is provided on one side of the threaded block, a plurality of positioning holes are provided on one side of the vertical frame, a positioning strip is provided on one side of the vertical frame, one end of the positioning strip is threadedly connected to the recessed hole and the plurality of positioning holes respectively, a first cleaning plate is provided inside the reinforcing frame, and a second cleaning plate is fixedly installed on one side of the vertical frame.

[0009] Preferably, a second servo motor is provided on one side of one of the arc-shaped plates, the processing table is fixedly sleeved on one end of the transmission rod, the output shaft of the second servo motor is connected to one end of the transmission rod, a water tank is provided inside the U-shaped frame, and a water pipe is provided on one side of the water tank.

[0010] Preferably, a water pump is provided on one side of the water pipe, one end of the water pipe is inserted and connected to the top of the wrapping plate, and one end of each of the multiple nozzles is fixedly inserted and connected to the bottom of the wrapping plate.

[0011] Preferably, two guide plates are fixedly installed on one side of the processing table, two straight plates are provided on one side of the U-shaped frame, an L-shaped plate is placed between the two straight plates, and round holes are provided on both sides of the L-shaped plate.

[0012] Preferably, each of the two straight plates is provided with a torsion strip on one side, and one end of each of the two torsion strips is respectively connected to the internal threads of two round holes. Multiple rubber strips are fixedly inserted and connected to the bottom of the L-shaped plate.

[0013] A welding method for a continuous welding apparatus for automotive radiator cores includes the following steps:

[0014] Step 1: Place the car radiator core onto the surface of the reinforcement frame in sequence, move the second cleaning plate downwards, and move the vertical rod and vertical frame downwards inside the threaded block. After the bottom surface of the second cleaning plate contacts the surface of the core, manually push the core.

[0015] Step 2: The surface and bottom of the core are rubbed against the first and second cleaning plates respectively to remove dirt and dust adhering to the surface of the core.

[0016] Step 3: After cleaning, the core is pushed onto the surface of the treatment table. As the water pump is started, water in the water tank is sprayed onto the surface of the core through multiple nozzles to improve the quality of core cleaning.

[0017] Step 4: After the processing table is tilted, the core slides onto the surface of the conveyor roller and is sequentially conveyed to the bottom of multiple welding heads. The welding heads then perform continuous and uniform welding on multiple radiator cores using laser welding.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention, through the cooperation of a threaded rod, a threaded block, a vertical rod, a positioning strip, a first cleaning plate, a second cleaning plate, and an arc-shaped plate, firstly places the car radiator core onto the surface of the reinforcement frame. The bottom surface of the core contacts the surface of the first cleaning plate. The second cleaning plate is pushed downwards, causing the vertical rod and the vertical frame to move downwards inside the threaded block. After the bottom surface of the second cleaning plate contacts the surface of the core, one end of the positioning strip is embedded into the positioning hole and the recessed hole. The three are threaded together, thereby limiting and fixing the threaded block and the vertical frame. After starting the first servo motor, the threaded rod connected to its output shaft is driven to rotate, which in turn causes the threaded block threaded with it to move. The threaded block then drives the second cleaning plate to move, and the second cleaning plate scrapes back and forth on the surface of the core, increasing the cleaning range of the second cleaning plate on the surface of the core for adhering dirt.

[0020] 2. This invention utilizes a combination of a second servo motor, transmission rod, nozzles, water tank, water pump, guide plate, and processing table. The cleaned core is manually pushed onto the surface of the processing table. The water pump is activated, and water from the tank flows along the water pipes to the interior of multiple nozzles, then continues to spray onto the core's surface. Spraying water reduces the contact between the metal surface and air, lowering the possibility of oxidation, thereby improving the joint strength and weld quality during core welding. Water spraying also helps provide a uniform humid environment for the core surface before welding, helping to maintain temperature consistency in the welding area. After the second servo motor is activated, it drives the transmission rod connected to its output shaft to rotate, which in turn drives the processing table fixedly mounted on it to rotate. As the processing table tilts, the cleaned core automatically slides onto the surface of the conveyor rollers.

[0021] 3. This invention utilizes a combination of a straight plate, an L-shaped plate, rubber strips, a twisting strip, a welding head, a conveyor roller, and an auxiliary seat. When the processing table tilts, the core slides onto the surface of the conveyor roller due to inertia. During this process, the core comes into contact with multiple rubber strips, which deform under pressure. The core is still transported normally to the surface of the conveyor roller. The rubber strips can shield the sprayed water, preventing large-scale splashing. The multiple conveyor rollers are connected by a coupling to automatically transport the cores one by one to the bottom of multiple welding heads. With the activation of the hydraulic cylinder and the micro motor, the position and height of the welding head can be adjusted, thus achieving continuous welding of the automotive radiator core.

[0031] like Figures 1 to 7 As shown, this invention provides a technical solution for a continuous welding device and welding method for automotive radiator cores:

[0032] Example 1:

[0033] like Figure 1-2As shown, a continuous welding device for automotive radiator cores includes a welding frame 1 and multiple conveying rollers 2. The multiple conveying rollers 2 are respectively disposed on the top of the welding frame 1. A support frame 3 is disposed on the top of the welding frame 1, and multiple hydraulic cylinders 4 are disposed at the bottom of the support frame 3. The output shafts of the multiple hydraulic cylinders 4 are all drivenly connected to auxiliary seats 5. Each of the multiple auxiliary seats 5 contains a micro motor, and the output shafts of the multiple micro motors are all drivenly connected to welding heads 6. A reinforcing frame 9 is disposed on the top of the welding frame 1. A threaded rod 10 is disposed inside the reinforcing frame 9. A threaded block 12 is sleeved at one end of the threaded rod 10. A vertical frame 14 is movably mounted on the outer surface of the threaded block 12. A vertical rod 13 is disposed inside the vertical frame 14. Two arc-shaped plates 19 are disposed on one side of the reinforcing frame 9. A transmission rod 21 is disposed between the two arc-shaped plates 19. A processing table 22 is sleeved at one end of the transmission rod 21. A U-shaped frame 2 is disposed on the top of the processing table 22. 3. The U-shaped frame 23 has a wrapping plate 24 inside, and multiple nozzles 25 are set at the bottom of the wrapping plate 24. A water collection box 7 is placed at the bottom of the welding frame 1. Two reinforcing plates 8 are set on both sides of the reinforcing frame 9. One side of the four reinforcing plates 8 is fixedly connected to the two sides of the welding frame 1. A first servo motor 11 is set on one side of the reinforcing frame 9. The vertical rod 13 and the threaded block 12 are movably inserted and connected. The output shaft of the first servo motor 11 is driven and connected to one end of the threaded rod 10. One end of the positioning strip 15 is embedded into the positioning hole 16 and the concave hole. The three are threadedly connected, so that the threaded block 12 and the vertical frame 14 can be limited and fixed. After the first servo motor 11 is started, it drives the threaded rod 10, which is driven and connected to its output shaft, to rotate, which also drives the threaded block 12, which is threaded and sleeved with it, to move. The threaded block 12 drives the second cleaning plate 18 to move, and the second cleaning plate 18 scrapes back and forth on the surface of the core.

[0034] Example 2:

[0035] Based on Example 1, such as Figure 2-5 As shown, a second servo motor 20 is provided on one side of one of the arc-shaped plates 19. The processing table 22 is fixedly sleeved on one end of the transmission rod 21. The output shaft of the second servo motor 20 is connected to one end of the transmission rod 21. A water tank is provided inside the U-shaped frame 23. A water pipe is provided on one side of the water tank. A water pump 26 is provided on one side of the water pipe.

Spraying water can reduce the contact between the metal surface and the air, reduce the possibility of oxidation, thereby improving the joint strength and weld quality during core welding. Spraying water helps to provide a uniform humid environment for the core surface before welding and helps to maintain the temperature consistency of the welding area.

[0036] Example 3:

When the rubber strips 30 are subjected to force, they will deform. The core body is still transported normally to the surface of the conveying roller 2. The rubber strips 30 can block the sprayed water and avoid large-scale water splashing. The multiple conveying rollers 2 are driven by a coupling to automatically transport the core body one by one to the bottom of the multiple welding heads 6.

[0038] A welding method for a continuous welding apparatus for automotive radiator cores includes the following steps:

[0039] Step 1: Place the car radiator core onto the surface of the reinforcement frame 9 in sequence, move the second cleaning plate 18 downward, and move the vertical rod 13 and the vertical frame 14 downward inside the threaded block 12. After the bottom surface of the second cleaning plate 18 contacts the surface of the core, push the core manually.

[0040] Step 2: The surface and bottom of the core are rubbed against the first cleaning plate 17 and the second cleaning plate 18 respectively, in order to remove dirt and dust attached to the surface of the core.

[0041] Step 3: After cleaning, the core is pushed onto the surface of the treatment table 22. As the water pump 26 is started, water in the water tank is sprayed onto the surface of the core through multiple nozzles 25 to improve the quality of core cleaning.

[0042] Step 4: After the processing table 22 is tilted, the core slides onto the surface of the conveying roller 2 and is sequentially conveyed to the bottom of multiple welding heads 6. The welding heads 6 then perform continuous and uniform welding on multiple radiator cores using laser welding.

[0043] The working principle and usage process of this invention: The radiator core is the core part of the car radiator, usually made of metal, and is responsible for heat dissipation. Its main function is to absorb the heat generated by the engine through flowing coolant and carry the heat away through the air outside the radiator, thereby maintaining the normal operating temperature of the engine. The radiator core has a series of coolant channels through which the coolant flows, absorbing the heat generated by the engine. The welding device is a specialized piece of equipment for producing car radiator cores. It uses continuous welding technology to weld the various components of the radiator core. During core welding, the components are often placed directly at the bottom of the welding head 6. However, when the components of the radiator core are covered with dirt and dust, these impurities will affect the fusion of the welding material. The welding joint is not strong enough, which affects the performance of the radiator. The temperature of the welding area on the core surface is not stable enough, and the radiator components are prone to deformation and cracking. To solve this problem, a continuous welding device for automotive radiator cores is designed. First, the automotive radiator core is placed on the surface of the reinforcement frame 9, with the bottom surface of the core in contact with the surface of the first cleaning plate 17. The second cleaning plate 18 is pushed downwards, which causes the vertical rod 13 and the vertical frame 14 to move downwards inside the threaded block 12. After the bottom surface of the second cleaning plate 18 contacts the surface of the core, one end of the positioning strip 15 is embedded into the positioning hole 16 and the recessed hole. The three are threaded together, which can limit and fix the threaded block 12 and the vertical frame 14. After the first servo motor 11 is started, it drives the vertical rod 13 and the vertical frame 14 to move downwards inside the threaded block 12. The output shaft drives the threaded rod 10 to rotate, which in turn moves the threaded block 12 that is threaded with it. The threaded block 12 then moves the second cleaning plate 18, which scrapes back and forth on the surface of the core, increasing the cleaning range of the core surface. After cleaning, the core is manually pushed onto the surface of the processing table 22, and the water pump 26 is started. Water in the water tank is guided along the water pipe to the interior of multiple nozzles 25, and then continues to be sprayed onto the surface of the core. Spraying water can reduce the contact between the metal surface and the air, reducing the possibility of oxidation, thereby improving the joint strength and weld quality during core welding. Spraying water helps to provide a uniform humid environment for the core surface before welding, and helps to maintain the temperature consistency of the welding area. After the second servo motor 20 is started, it drives the transmission rod 21, which is connected to its output shaft, to rotate, thus driving the processing table 22, which is fixedly mounted thereon, to rotate. As the processing table 22 tilts, the cleaned core will automatically slide onto the surface of the conveyor roller 2. During this process, the core will come into contact with multiple rubber strips 30. The rubber strips 30 will deform under force, and the core will still be transported normally to the surface of the conveyor roller 2. The rubber strips 30 can block the sprayed water, avoiding large-scale water splashing. The multiple conveyor rollers 2 are connected by a coupling to automatically transport the core one by one to the bottom of multiple welding heads 6. This is coordinated with the start of the hydraulic cylinder 4 and the micro motor.The height of the welding head 6 can be adjusted to achieve continuous welding of the automotive radiator core. Reversing the two twisting strips 31 allows them to disengage from the inside of the round hole, facilitating the separation of the L-shaped plate 29 from the two straight plates 28 for replacement with a brand new L-shaped plate 29. This also facilitates separate cleaning of the L-shaped plate 29 and the rubber strip 30.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
