Description

Technical Field

[0001] The invention relates to the technical field of magnesium alloy processing, in particular to equipment and a method for trimming and deburring magnesium alloy parts. Background Art

[0002] Magnesium alloy is an alloy composed of magnesium as the matrix and other elements. Magnesium alloy is the lightest metal among practical metals. The specific gravity of magnesium is about 2 / 3 of aluminum and 1 / 4 of iron. It has high strength and high rigidity. Magnesium alloy has a series of advantages such as low density, high specific strength and specific rigidity, good impact resistance, etc. The main alloying elements are aluminum, zinc, manganese, cerium, thorium and a small amount of zirconium or cadmium. The most widely used is magnesium-aluminum alloy, followed by magnesium-manganese alloy and magnesium-zinc-zirconium alloy. It is mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors.

[0003] In the processing of magnesium alloy parts, it is necessary to trim the magnesium alloy parts as needed, and a large number of burrs will be generated on the cut edges after trimming. These burrs not only affect the subsequent assembly of magnesium alloy parts, but the burrs are relatively sharp and can easily cause damage to workers' hands. In order to solve the burr problem, the prior art CN220921790U proposes a deburring device for aluminum-magnesium alloy die-castings, which uses a grinding rod to grind the alloy parts to remove burrs.

[0004] Although the device can realize the grinding and deburring of magnesium alloy parts, the device is only applicable to some parts with regular edges and is difficult to apply to some parts with sharp edges. At the same time, the above-mentioned deburring device will generate a large amount of magnesium alloy debris during deburring. These debris are thrown up by the rotation of the grinding rod and are easily inhaled by workers, seriously affecting their health. For this reason, we provide a magnesium alloy part trimming and deburring device and method to solve the above-mentioned problems. Summary of the invention
