technical field

The invention belongs to the technical field of amorphous alloys, and in particular relates to an ultrasonic deburring method and system for amorphous alloys.

Background technique

After the amorphous alloy die-casting is formed, the product will have flashes, burrs, etc., and the hardness of the amorphous alloy is high, and the cost of removing these burrs is relatively high. Generally, there are manual removal, grinding and other methods for removing burrs from amorphous alloys. The cost of manual removal is high, the efficiency is not very high, and phenomena such as overgrinding and notches are prone to occur. For some larger and thicker burrs, there are some problems that cannot be completely removed by grinding. Phenomenon.

Ultrasonic deburring of general aluminum alloys is to put the casting billet with burrs into the ultrasonic lower mold for positioning, and the ultrasonic upper mold quickly falls vertically to press the thicker part of the billet and emit super strong sound waves to connect the product with the burrs for minimum punishment.
