Abstract

The invention relates to flexible deformation brazing filler metal and an automatic preparation device and a preparation method thereof. The flexible deformation brazing filler metal comprises Bi, In,Ag and Sn. The preparation device comprises an intermediate frequency furnace, a cover body, a vacuum adjusting system and a control system. A flow nozzle is arranged at the bottom end of the intermediate frequency furnace, an electromagnetic valve connected with the control system is arranged on the flow nozzle, and a thin pipe is arranged at the bottom of the furnace wall. A constant pressure valve, a double-shaft mechanical stirring device and a thermocouple are arranged on the cover body. The double-shaft mechanical stirring device comprises a motor, a speed reducer and two stirring rods.The motor and the thermocouple are connected with the control system. The vacuum adjusting system comprises a high-pressure gas device, a pressure sensor and a vacuum pump. The flexible deformation brazing filler metal is low in melting temperature, good in wettability, high in plasticity, good in extensibility and high in machinability. The device can achieve highly-automatic production of the flexible deformation brazing filler metal. The preparation method is simple, easy to operate, high in production efficiency and reliable in product quality.

Description

technical field [0001] The invention relates to the technical field of solder and its preparation method, in particular to a flexible deformable solder and its automatic preparation device and preparation method. Background technique [0002] Brazing has been widely used in the connection of two materials. With the development of science and technology, more and more industries are developing towards automation. Nowadays, there are many automatic processing devices, and there are also many semi-automatic or fully automatic brazing robots. Its own poor plasticity and poor machinability increase the difficulty of automatic brazing and efficient brazing. [0003] In order to solve the poor plasticity and poor machinability of the solder itself, many solutions have been proposed, such as powder, paste and paste solder, but many problems have been encountered in use, such as powder, paste and paste solder after welding. The material is easy to block the pore structure of the par...
