Embodiment Construction

[0025] Such as figure 1 As shown, the magnesium alloy digital camera shell hydroforming special mold with movable punch includes hydraulic chamber 1, bolt 2, die 3, punch fixing plate 4, blank holder 5, fixed punch 6, connecting bolt 7, Spring 8, limit block 9, movable punch 10, blank 11, heating element 12, upper die base 13, etc., hydraulic chamber 1 is connected with die 3 through bolt 2, fixed punch 6, connecting bolt 7, spring 8. The limit block 9 and the movable punch 10 form a block-type combined drawing punch. The fixed punch 6 is fixed on the upper die base 13 through the fixed plate 4. The movable punch 10 is set on the The spring 8 on the connecting bolt 7 is connected with the fixed punch 6, the spring 8 is placed between the fixed punch 6 and the movable punch 10, and the movable punch 10 passes through the wedge-shaped groove 14 on it along the side wall of the fixed punch. The wedge-shaped slideway 17 moves up and down, and its position is controlled by being inst

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.
