7. The method for preparing a high performance Jin Jiyin palladium alloy bonding material according to any one of claims 1 to 6, comprising the steps of:

s1, weighing metal raw materials: weighing metal materials such as gold, silver, palladium, copper, zinc, chromium, ruthenium and the like according to parts by weight, and reserving;

s2, preparing a copper-zinc-chromium-ruthenium quaternary alloy cast ingot: mixing the copper, zinc, chromium and ruthenium weighed in the steps, carrying out vacuum smelting, pouring the mixture into a mould after melting the mixture into copper-zinc-chromium-ruthenium mixed solution, and preparing a copper-zinc-chromium-ruthenium quaternary alloy cast ingot;

s3, preparing gold-silver-palladium alloy blocks: the gold, silver and palladium weighed in the steps are respectively placed into the inner side of an annular crucible (34), the furnace body (1) is vacuumized due to the fact that three partition plates (74) are blocked in a cavity formed, meanwhile, a heating mechanism (2) and an inner heating pipe (33) are started, and the heating mechanism (2) and the inner heating pipe (33) respectively heat and melt three metal raw materials from the outer side and the inner side;

at the moment, the driving motor (42) drives the first driving shaft (43) to rotate clockwise, the second driving shaft (46) does not rotate due to the limitation of the overrunning clutch, the first driving shaft (43) drives the rotating column (52) to rotate through the connecting shaft (51), and the ripple groove (53) drives the lifting sleeve (56) to repeatedly lift outside the rotating column (52) through the two sliding columns (54) and the connecting lug (55);

in the repeated lifting process of the lifting sleeve (56), the second reciprocating screw rod (61) is driven to synchronously and repeatedly lift, the second reciprocating screw rod (61) drives the repeated partition plate (74) to lift through the threaded sleeve ring (62) when the second reciprocating screw rod (61) repeatedly lifts, when the threaded sleeve ring (62) lifts, the partition plate (74) synchronously lifts along with the threaded sleeve ring (62), the stirring plate (75) stretches out of the partition plate (74) due to gravity, the separation between three metal liquids is relieved, mutual fusion is started, and when the threaded sleeve ring (62) descends, the partition plate (74) descends synchronously along with the threaded sleeve ring (62), and then the metal mixed liquid is vibrated;

in addition, along with the lifting of the threaded sleeve ring (62), the threaded sleeve ring (62) continuously drives the limit sliding block (65) to extrude the spring (66), when the threaded sleeve ring (62) cannot lift due to the elastic force limitation of the spring (66), the threaded sleeve ring (62) starts to rotate at the outer side of the second reciprocating screw rod (61), and then drives the plurality of partition plates (74) and the stirring plate (75) to rotate in the annular crucible (34), so that the metal mixed liquid is stirred and mixed;
