[0021] Please refer to Figures 1 to 4 , in the embodiments of the present utility model, a rapid diffusion welding processing device includes: a preheating tunnel furnace 1, a welding mechanism 2, and a cooling mechanism 3 that are connected in sequence;

[0022] During processing, the product to be processed is placed in the corresponding processing fixture, and the processing fixture is pushed in by an external feeding device and sequentially enters the preheating tunnel furnace 1, the welding mechanism 2, and the cooling mechanism 3 to perform preheating, welding, and cooling operations in the diffusion welding process. Finally, the processing fixture that has completed processing is sent out from the cooling mechanism 3 to complete the processing action;

[0023] And in order to improve the stability of the welding process, when the preheating tunnel furnace 1, the welding mechanism 2, and the cooling mechanism 3 are in operation, the oxygen content in the processing environment is reduced by filling inert gas.

[0024] The preheating tunnel furnace 1 includes: a preheating furnace body 11 and a single-station channel 12 provided in the preheating furnace body 11; one end of the single-station channel 12 is a feeding section, which is connected to an external transitional feeding device; the other end is connected to the welding mechanism 2; the width of the single-station channel 12 corresponds to the length of the processing fixture;

[0025] The welding mechanism 2 includes: a welding machine frame 23, and a welding processing chamber 24 connected to the preheating tunnel furnace 1 and the cooling mechanism 3 is provided in the welding machine frame 23. The welding processing chamber 24 is a sealed cavity and can be externally connected to an air extraction pump. Through the air extraction pump, the oxygen in the welding processing chamber 24 can be discharged to prepare for the filling of inert gas;

[0026] Two groups of welding devices 21 and at least one group of slow cooling devices 22 are also provided on the welding machine frame 23. Each group of welding devices 21 is arranged in sequence, and the slow cooling device 22 is arranged at the end position of the welding machine frame 23;

[0027] Both the welding device 21 and the slow cooling device 22 include: a pressurizing drive module 221, a welding head 222, and a welding seat 223. Among them, both the welding head 222 and the welding seat 223 are arranged in the welding processing chamber 24. The piston rod of the pressurizing drive module 221 is in transmission cooperation with the pressurizing seat, driving it to press vertically towards the welding seat 223 for pressurizing work.

[0028] Each welding seat 223 is connected in sequence to form a welding channel connected to the single-station channel 12. During processing, the processing fixture will enter the welding seat 223, and a diffusion welding processing procedure will be carried out through the welding device 21. Finally, it will enter the slow cooling device 22 for the slow cooling processing action after welding, avoiding the situation where the product directly enters the cooling device 32, resulting in excessive errors.

[0029] In conventional processing, the product only needs to enter a set of welding devices 21 for processing to complete the diffusion welding processing action, and the second set of welding devices 21 will work according to the processing requirements of special products.

[0030] Among them, both the welding head 222 and the welding seat 223 are made of graphite plate structures and are connected to external heating equipment through heating tubes. And because the pressing forces required for processing by the welding device 21 and the slow cooling device 22 are different, the pressurizing drive module 221 in the welding device 21 adopts a hydraulic pressurizing drive structure, while the pressurizing drive module 221 in the slow cooling device 22 adopts a cylinder pressurizing drive structure.

[0031] The cooling mechanism 3 includes: a cooling channel 31, and the cooling channel 31 is respectively connected to the welding mechanism 2 and an external transitional feeding device. The inside of the cooling channel 31 is a sealed cavity and can be externally connected to an air extraction pump. Through the air extraction pump, the oxygen in the cooling channel 31 can be discharged to prepare for the filling of inert gas.

[0032] The cooling mechanism 3 also includes: a plurality of sets of cooling devices 32 arranged in sequence along the discharging direction of the cooling channel 31. The cooling device 32 includes: a cooling pressurizing device 321 installed on the cooling channel 31 and a cooling plate 322 arranged in the cooling channel 31. The piston rod of the cooling pressurizing device 321 penetrates into the cooling channel 31 and is connected and cooperated with the cooling plate 322. During processing, the cooling pressurizing device 321 drives the cooling plate 322 to move downward to contact the processing fixture, achieving the effect of pressurized cooling.
