[0027] By adopting the above technical scheme, firstly, the gas tank 501 supplies gas to the airbag 505 through the cooperation of the gas supply valve 503 and the delivery pipe 502. The airbag 505 is fixed in the inside of the placement tube 4 through the fixing plate 506. When the inflation is completed, the contact plate 507 is pushed to penetrate into the processing box 1 through the placement groove 3, and the material is evenly pressed onto the diffusion welding device for diffusion welding. The sealing gasket 7 bonded with the installation groove 6 is improved to improve the sealing performance to avoid gas leakage when the processing box 1 is in a vacuum state. The exhaust is carried out through the cooperation of the delivery pipe 502 and the exhaust valve 504 to avoid the increase of overheated gas pressure during the welding process, which affects the stability of the pressing and thus affects the accuracy of the material. The visualization window 2 made of tempered glass is convenient for viewing the internal welding situation. The gas supply valve 503 and the exhaust valve 504 are controlled and set by the PLC end of the equipment. The gas pressure required for welding (5MPa) can be maintained by the intake and exhaust according to the demand to maintain a uniform air pressure inside the airbag 505.

[0028] Specifically, Figures 1 to 4 As shown, an adjusting mechanism 8 is arranged on the outside of the placing cylinder 4, and the adjusting mechanism 8 includes a mounting hole 801, and the mounting hole 801 is opened at the overflow of the placing groove 3 at the top of the processing box 1, and a hydraulic rod 802 is embedded in the mounting hole 801, and the power output end of the hydraulic rod 802 is connected with a connecting plate 803, and the internal sliding connection of the connecting plate 803 is connected with a limiting rod 804, and the adjusting mechanism 8 also includes a limiting block 805, and the limiting block 805 is fixed on the outer wall of the resistance plate 507, and a limiting groove 806 is opened on the inner wall of the placing groove 3 corresponding to the position of the limiting block 805, and a sliding structure is formed between the connecting plate 803 and the limiting rod 804, and the connecting plate 803 forms a telescopic structure with the processing box 1 through the hydraulic rod 802, and a sliding structure is formed between the limiting block 805 and the placing cylinder 4, and a sliding structure is formed between the limiting block 805 and the placing groove 3 through the limiting groove 806.

[0029] By adopting the above technical scheme, the material is first placed into the processing box 1 through the placement groove 3 and is located above the diffusion welding device. Then, the hydraulic rod 802 embedded in the installation hole 801 works, so that the connecting plate 803 drives the placement cylinder 4 to move and penetrate into the placement groove 3. With the cooperation of the resistance mechanism 5, the material is resisted and then welded. When the connecting plate 803 slides, it is stabilized by the limit rod 804 to avoid displacement or shaking. When the resistance plate 507 moves, it slides along the reserved groove of the placement cylinder 4 and the limit groove 806 through the limit block 805 to keep the resistance plate 507 sliding stably to avoid displacement that affects the comprehensiveness of the compacted material.

[0030] Working principle: a diffusion welding device is provided inside the processing box 1, and it is conveniently in a vacuum form through the adaptation of vacuum pumps and other components. At the same time, the visual window 2 is used to facilitate viewing of the internal welding situation. First, the material is placed inside the placement groove 3 and corresponds to the diffusion welding device. Then, the hydraulic rod 802 embedded in the mounting hole 801 of the processing box 1 works, and the contraction drives the connecting plate 803 to move stably along the limit rod 804 to cover the material. Then, under the control of the gas tank 501 and the gas delivery valve 503, the air bag 505 is inflated through the conveying pipe 502. The air bag 505 is fixed by the fixing plate 506 to prevent it from detaching, and the contact plate 507 is pushed to slide along the reserved groove of the placement tube 4 through the limit block 805, and enter the limit groove 806 to contact the material for sufficient compression. When the heat-generating gas pressure increases during processing, the gas in the air bag 505 is discharged through the cooperation of the exhaust valve 504 and the conveying pipe 502, and the same pressure is maintained for contact to avoid errors. The sealing gasket 7 bonded by the mounting groove 6 improves the sealing of the placement groove 3.
