Embodiment 1

[0039] This example is used to illustrate the method for removing burrs from amorphous alloy products disclosed in the present invention.

[0040] The cuboid zirconium-based amorphous alloy product is prepared by die-casting, and there are burrs with a thickness less than 0.07mm at the edges and corners through microscopic observation.

[0041]Use natural gas as gaseous combustibles, use air as combustion-supporting gas to ignite, adjust the flame temperature to 600°C, and burn the burr with flame for 2s. Then extinguish the flame.

[0042] After the zirconium-based amorphous alloy product is cooled, the burrs are ground and cleaned.

[0043] Through microscopic observation, it was determined that the burrs had been completely removed, and the zirconium-based amorphous alloy product itself was not damaged.

Embodiment 2

[0045] This example is used to illustrate the method for removing burrs from amorphous alloy products disclosed in the present invention.

[0046] Die-casting is adopted to prepare a rectangular parallelepiped titanium-based amorphous alloy product, and through microscopic observation, there are burrs with a thickness less than 0.2mm at the edges and corners.

[0047] Use natural gas as gaseous combustibles and air as a combustion-supporting gas to ignite, adjust the flame temperature to 1800°C, and burn the burr with flame for 0.5s. Then extinguish the flame.

[0048] After the titanium-based amorphous alloy product is cooled, the burrs are ground and cleaned.

[0049] Through microscopic observation, it was determined that the burrs had been completely removed, and the titanium-based amorphous alloy product itself was not damaged.

Embodiment 3

[0051] This example is used to illustrate the method for removing burrs from amorphous alloy products disclosed in the present invention.

[0052] Die-casting is adopted to prepare a cuboid copper-based amorphous alloy product, and through microscopic observation, there are burrs with a thickness less than 0.1mm at the edges and corners.

[0053] Use natural gas as gaseous combustibles and air as a combustion-supporting gas to ignite, adjust the flame temperature to 500°C, and use the flame to burn the burr for 3s. Then extinguish the flame.

[0054] After the copper-based amorphous alloy product is cooled, the burrs are ground and cleaned.

[0055] Through microscopic observation, it was determined that the burrs had been completely removed, and the copper-based amorphous alloy product itself was not damaged.

Abstract

The invention provides a method for removing raw edges of amorphous alloy products, aiming to solve the problem of difficulty in moving the raw edges of the amorphous alloy products in the prior art. The method includes S1, providing the amorphous alloy products with the raw edges, wherein at least one of three dimensions of each raw edge is smaller than 0.3mm; S2, firing the raw edges with flames at the temperature of 500-2000 DEG C within three seconds; S3, grinding and cleaning the fired amorphous alloy products. The method has the advantages that the raw edges of the amorphous alloy products can be removed effectively, damage to the amorphous alloy products is avoided, special equipment and tools are not needed, and the method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of die-casting product production technology, and more specifically, the invention relates to a method for removing burrs of amorphous alloy products. Background technique [0002] Amorphous alloys appeared in the 1960s. The initial amorphous alloys could only reach the micron level because of the critical size (the largest size of amorphous crystals), so it was difficult to be practically applied. However, due to its excellent material properties, it was favored by scientists Extensive research and continuous development of amorphous alloys with large critical size and suitable for industrial production. The critical size gradually develops from micron level to millimeter level or even centimeter level. Usually, the critical cooling rate is lower than 500°C / s Amorphous alloys with a critical size greater than 1mm are called bulk amorphous alloys. The emergence of bulk amorphous alloys provides the possibili...
