This invention relates to the field of electromagnetic relay manufacturing technology, and discloses an ultra-high frequency induction brazing device for an electromagnetic relay contact spring system, comprising: a worktable, a fixture, a moving mechanism, and an ultra-high frequency induction brazing machine; the fixture is disposed on the worktable surface and is used to clamp and fix the contact spring system; during welding, a spring sheet is sleeved on the Kovar alloy lead-out rod in the contact spring system to form a welding point between the two; the output end of the moving mechanism can move along a first direction and a second direction, and the induction brazing head of the ultra-high frequency induction brazing machine is disposed on the moving mechanism; during operation, the moving mechanism drives the induction brazing head to move along the first direction and the second direction, so that the induction coil of the induction brazing head is aligned with each welding point. This device adopts non-contact induction heating, completely avoiding the use of carbon rod electrodes, eliminating the generation of excess carbon powder from the source, and greatly improving the internal cleanliness and long-term operational reliability of the electromagnetic relay.

This utility model discloses a processing device suitable for induction brazing of electromagnetic relay housing assemblies, relating to the field of relay housing assembly processing technology. It includes: a feeding mechanism, a positioning mechanism, a pressing mechanism, and a brazing heating mechanism. The feeding mechanism is used to pick up the housing assembly to be brazed onto the heating seat of the brazing heating mechanism; the positioning mechanism is used to push the housing assembly to be brazed onto the heating seat to a target positioning point; the pressing mechanism is used to press the housing assembly to be brazed onto the target positioning point using a pressing head, so that the heating coil of the brazing heating mechanism can perform the welding operation. This utility model alleviates the technical problem of low production efficiency in the manual operation mode of resistance brazing.

This invention relates to the field of surface strengthening technology, specifically to a diamond composite brazing coating and its preparation method. The invention first mixes a brazing powder containing a first brazing filler metal powder, diamond abrasive, and flux with an organic binder to form a flexible strip-shaped brazing filler metal. Then, after a first pre-firing process, a porous, pore-fillable skeleton structure is formed. This skeleton structure is then embedded in a filler powder containing a second brazing filler metal powder and a powder binder, and ultrasonic vibration is used to fill the pores. After a second pre-firing process, it is placed on a substrate surface for induction brazing. This method can actively compensate for and repair pore defects caused by the volatilization of the organic binder before brazing, reducing pore residue in the coating after welding, improving the coating's density, surface smoothness, and abrasive bonding stability, and significantly improving the coating's surface quality.
