[0002] Diffusion welding means that the surfaces of mutually contacting materials approach each other under the action of temperature and pressure, local plastic deformation occurs, atoms diffuse mutually, and a new diffusion layer is formed at the interface, thereby realizing reliable connection. This technology is widely used in fields such as aerospace, nuclear energy, electronics, and precision instrument manufacturing. It is divided into solid-phase diffusion welding and liquid-phase diffusion welding. When performing diffusion welding, a feeding operation is required. The types of materials required for diffusion welding are numerous, including metal materials, ceramic materials, composite materials, and other special materials, etc.

By starting the first motor 7 and using the setting of the lifting screw rod 11 and the mounting plate 12, the first motor 7 drives the driven bevel gear 9 to rotate on the steering wheel 6 through the driving bevel gear 8, so that the driven bevel gear 9 drives the lifting screw rod 11 to rotate, thereby driving the mounting plate 12 to move upward on the lifting seat 10, and then the lifting seat 10 drives the clamping block 13 to move upward through the mounting plate 12, realizing the movement of the material in the vertical direction. The stability of the material during the feeding process is improved by using the setting of the clamping block 13. After that, the electric push rod 3 is started, and by using the cooperation of the steering gear 5 and the rack 4, the steering wheel 6 is rotated 180 degrees, realizing the smooth turning of the material, making it close to the operation box 27, simplifying the material transfer process, avoiding errors and inconveniences caused by long-distance movement, improving production efficiency, and ensuring the continuity and stability of the welding operation.

[0030] In addition, a second motor 14 is fixedly installed inside the mounting plate 12. The output end of the second motor 14 is fixedly connected to a worm 15. A worm gear 16 is meshed with the worm 15. A connecting rod 17 is fixedly connected to the worm gear 16. A clamping head 18 is hinged to the connecting rod 17. A connecting strip 19 is rotatably connected to the clamping block 13. The connecting strip 19 is hinged to the clamping head 18. When the second motor 14 is started, the second motor 14 drives the two worm gears 16 to rotate through the worm 15. Since both are meshed with the worm 15, the worm gears 16 drive the two connecting rods 17 to approach each other in the middle, thereby driving the two clamping heads 18 to approach each other in the middle. At the same time, the clamping head 18 also drives the connecting strip 19 to rotate on the clamping block 13. The materials to be welded are clamped by the mutual approach of the two clamping heads 18, and materials of different sizes can be clamped, improving the adaptability of the device. The clamping is stable and not easy to loosen, enhancing the stability of the materials during the feeding process. A fixed seat 20 is fixedly connected to the base 1. A third motor 21 is fixedly installed inside the fixed seat 20. The output end of the third motor 21 is fixedly connected to a moving threaded rod 22. A threaded sleeve 23 is threadedly connected to the moving threaded rod 22. The threaded sleeve 23 is fixedly connected to the adjusting seat 2. Slide rods 24 are fixedly connected to both sides of the adjusting seat 2. Slide rails 25 are fixedly connected to both sides of the base 1. The slide rods 24 are slidably connected to the slide rails 25. When the third motor 21 is started, the moving threaded rod 22 drives the threaded sleeve 23 and the entire adjusting seat 2 to move directionally on the base 1. The limiting effect of the slide rods 24 and the slide rails 25 prevents deviation and shaking, enabling the materials to be welded to be transported between the lower pressing head 28 and the upper pressing head 30, realizing automatic feeding operation, which is beneficial to the improvement of production efficiency. A support rod 26 is fixedly connected to the fixed seat 20. An operation box 27 is fixedly connected to the support rod 26. A lower pressing head 28 is fixedly connected inside the operation box 27. A hydraulic rod 29 is provided on the operation box 27. The output end of the hydraulic rod 29 is fixedly connected to an upper pressing head 30. A heating pipe 31 is provided on the operation box 27. The heating pipe 31 is connected to the upper pressing head 30. When the hydraulic rod 29 is started, the hydraulic rod 29 drives the upper pressing head 30 to move downward, applying pressure to the materials on the lower pressing head 28. At the same time, the heating pipe 31 is started, and the upper pressing head 30 is heated by multiple heating pipes 31, thereby realizing uniform heating of the weldment. The upper pressing head 30 can apply appropriate pressure through the hydraulic rod 29. Combining with the heating effect of multiple heating pipes 31 provided, diffusion welding of the materials can be realized, improving the welding quality and production efficiency. The rack 4 slides inside the adjusting seat 2. The steering gear 5 rotates on the adjusting seat 2. The lifting threaded rod 11 rotates inside the lifting seat 10. The mounting plate 12 slides on the lifting seat 10. The worm 15 and the worm gear 16 both rotate on the clamping block 13. There are two worm gears 16 and both are meshed with the worm 15. There are two clamping heads 18 and they are symmetrically arranged on the clamping block 13. The operation box 27 is located above the fixed seat 20. The lower pressing head 28 is located below the upper pressing head 30.There are multiple heating tubes 31 which are evenly distributed on the upper pressure head 30.

[0031] Working principle: When using the diffusion welding device with automatic feeding, the operator starts the second motor 14. The second motor 14 drives two groups of worm wheels 16 to rotate through the worm 15. Since both groups are meshed with the worm 15, the worm wheels 16 drive two groups of connecting rods 17 to move closer to each other in the middle, thereby driving two groups of clamping heads 18 to move closer to each other in the middle. At the same time, the clamping heads 18 also drive the connecting strip 19 to rotate on the clamping block 13. By the mutual approach of the two groups of clamping heads 18, the material to be welded is clamped, and it is not easy to loosen. Then the operator starts the first motor 7. The first motor 7 drives the driven bevel gear 9 to rotate on the steering wheel 6 through the driving bevel gear 8, so that the driven bevel gear 9 drives the lifting screw rod 11 to rotate, thereby driving the mounting plate 12 to move upward on the lifting seat 10. Furthermore, the lifting seat 10 drives the clamping block 13 to move upward through the mounting plate 12, realizing the movement of the material in the vertical direction. Then start the electric push rod 3. The electric push rod 3 drives the steering gear 5 to rotate through the rack 4, so that the steering gear 5 drives the steering wheel 6 to rotate, and rotates the steering wheel 6 by 180 degrees, realizing the conversion of the position of the clamping block 13 and the material clamped on the clamping block 13, making it close to the operation box 27. Then start the third motor 21. The third motor 21 drives the moving screw rod 22 to rotate, so as to drive the adjusting seat 2 on the base 1 to move towards the fixed seat 20 through the thread sleeve 23 threadedly connected to the moving screw rod 22. The movement of the adjusting seat 2 is limited by the slide rod 24 and the slide rail 25, so as to move the material to be welded on the clamping block 13 between the lower pressure head 28 and the upper pressure head 30. Then reverse the rotation of the output end of the second motor 14, so as to loosen the material and place it stably on the lower pressure head 28. Then reverse the rotation of the output end of the third motor 21, so that the adjusting seat 2 and the clamping block 13 retreat a certain distance. Start the hydraulic rod 29, so that the hydraulic rod 29 drives the upper pressure head 30 to move downward, applying pressure to the material on the lower pressure head 28. At the same time, start the heating tube 31, and use the heating tube 31 to heat the upper pressure head 30, thereby realizing the diffusion welding of the material. When the welding is completed, restart the second motor 14 and the third motor 21 to clamp the welded material, and then start the electric push rod 3, so that the steering wheel 6 rotates, thereby transporting the welded material to the next process. Then, according to the above steps, start a new feeding and diffusion welding operation again.
