7. The preparation method of the high-performance gold-based silver-palladium alloy bonding material according to any one of claims 1 to 6, characterized by comprising the following steps:

s3, preparing a gold-silver-palladium alloy block: placing the gold, silver and palladium weighed in the steps into the inner side of an annular crucible (34) respectively, vacuumizing a furnace body (1) in a cavity formed by blocking by three partition plates (74), starting a heating mechanism (2) and an inner heating pipe (33) simultaneously, and heating and melting three metal raw materials by the heating mechanism (2) and the inner heating pipe (33) from the outer side and the inner side respectively;

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 corrugated 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 process that the lifting sleeve (56) is repeatedly lifted, the second reciprocating screw rod (61) is driven to synchronously and repeatedly lift, when the second reciprocating screw rod (61) is repeatedly lifted, the threaded sleeve ring (62) drives the repeated partition plate (74) to lift, when the threaded sleeve ring (62) is lifted, the partition plate (74) synchronously lifts along with the threaded sleeve ring (62), the stirring plate (75) extends out of the partition plate (74) due to gravity, the three kinds of metal liquid are separated and begin to be fused with each other, and when the threaded sleeve ring (62) is lowered, the partition plate (74) synchronously lowers along with the threaded sleeve ring (62), so that the metal mixed liquid is vibrated;

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

after mixing, stopping the heating mechanism (2) and the internal heating pipe (33), taking out the annular crucible (34) with the interior of the furnace body (1), and casting the mixed molten metal into a mold to prepare a gold-silver-palladium alloy block;
