Abstract

The invention relates to a casting method of an alloy workpiece and discloses a casting method of an aluminum-magnesium alloy movable coil for a vibrating table. The method comprises the following steps of: 1, making preparations for pouring; 2, smelting and pouring; and 3, performing sand casting and gravity pouring, shaping an upper box, a middle box and a lower box, performing alloy smelting by a solvent method and performing gravity pouring. By the method, casting of the aluminum-magnesium alloy movable coil with a large and special structure is realized and various indexes meet design requirements; and the method has the advantages that: a casting does not have cracks and shrinkage cavities, has high quality and the like.

Description

technical field [0001] The invention relates to a casting method of an alloy workpiece, in particular to a casting method of an aluminum-magnesium alloy moving coil of an electric vibrating table. Background technique [0002] The electric vibration table is a kind of equipment for vibration simulation test of products or components. The anti-vibration performance of a product is evaluated through the test, which provides a correct basis for assessing the quality of the product. Therefore, it is widely used in aerospace, aviation, ships, automobiles, Electronics, home appliances and instrumentation industries. With the development of science and technology, the thrust and frequency of vibration test instruments are constantly increasing. The "heart" of vibration instruments - the structure of the moving coil is becoming more and more complex, and the parts are getting bigger and bigger. The original single-layer structure has developed into two layers. (Add a layer of parti...
