Abstract

The invention relates to the hydraulic forming technology of an alloy plate, in particular to a magnesium alloy digital camera casing with a movable male die and a similar product hydraulic forming special-purpose die assembly. The technology is mainly used for the heating, the hydraulic pressure, the drawing and the forming of the magnesium alloy sheet material. The die assembly is provided with a hydraulic pressure room, a concave die, a clamping ring, a drawing male die and a heating element. The drawing male die adopts a blocking type composite structure, and comprises a fixed male die and a movable male die moving along a slip way up and down. The movable element in the combined drawing male die improves the deformation sequence and the stressed state of a forming part, to lead the limit of the sheet material to being formed and the rate of finished products to be improved. The invention has the advantages that the availability of material is high, the surface quality of a manufactured product is good, the rigidity is high, the shape and the dimension precision are high, the invention can form a complicated plate part with a digital camera casing and other shapes, in particular to the plate part required to be heated and formed when forming a magnesium alloy plate part; the service life of the die assembly is long, the replacement is simple, and the process and the installation are simple.

Description

technical field [0001] The invention relates to alloy plate hydroforming technology, in particular to a magnesium alloy digital camera with a movable punch and a special mold for hydroforming shells of similar products, which is mainly used in warm and hydraulic deep drawing of magnesium alloy plates. Background technique [0002] Metal magnesium and its alloys are the lightest structural metal materials used in engineering so far. Magnesium alloys characterized by light weight, good rigidity, good metallic luster, good electromagnetic shielding and easy recycling have become modern automobiles, electronics, The preferred material for communication and other industries. Sheet metal deep drawing processing has significant advantages in improving product quality, productivity, and saving materials, and can process thin-walled parts that meet the requirements of electronic products. For general metals and their alloys, deep drawing is a very mature technology, but for magnesiu...
