Embodiment Construction

[0024] In this example, the Figure 1-A and Figure 1-B The single-part drawings shown in are for object specific description. The part 1 is an aluminum alloy hollow shell with a branch-like part 2 at the bottom.

[0025] The present invention will process the mold that part 1 adopts such as figure 2 As shown, it mainly includes vertical punch 3, upper connecting template 4, active radial outer mold sleeve 5, left split die 6, right split die 7, right connecting head 8, left connecting head 9, right connecting rod 10, left connecting rod 11, right horizontal connecting template 12, left horizontal connecting template 13, guide rail seat plate 14.

[0026] The vertical punch 3 is independently connected and driven by the punching cylinder of the multi-directional forming hydraulic press to move vertically up and down. The vertical punch 3 is positioned above the left split die 6 and the right split die 7, and is aligned at the opening of the die cavity. The upper connectin...

Abstract

The invention mainly discloses a multidirectional extrusion molding process and a multidirectional extrusion molding die for an aluminum alloy shell parts with branches. The die mainly comprises driving radial outer sleeves, two split female dies, and a vertical male die. The split female dies are vertically symmetrical to each other and are fixed on a stroke mechanism and can move horizontally; and a model cavity which has a part shape is formed in each split female die. The driving radial outer sleeves are sleeved outside the split female dies; and the inner die surfaces of the driving radial outer sleeves are in fit with the outer die surfaces of the split female dies. The invention also discloses the molding process implemented by using the die. The process comprises the following steps of: performing multidirectional extrusion on the aluminum alloy shell part blank with branches by using the multidirectional extrusion die, placing the blank in a die cavity of the die, and forming the aluminum alloy shell part with branches at one time under the continuous action. The invention effectively overcomes the problems of the conventional manufacturing processes, such as the extrusion molding process, a casting process, a welding process and the like, and the die has a simple structure and a high forming property.

Description

technical field [0001] The invention relates to the technical field of plastic processing technology and forming of metal materials, in particular to the forming of aluminum alloy branches and buds shell parts. Background technique [0002] Aluminum alloy has the characteristics of high strength, corrosion resistance, light weight (about one-third of the specific gravity of steel), good processability and is suitable for various processing such as pressing, welding, forging, etc., and meets the requirements of industrial applications and aerospace applications. Material selection standard. Aluminum alloy branch shell parts are widely used in the fields of weaponry, aviation and power engineering, oil and gas industry, etc. because of their light weight and high pressure resistance. Due to its special shape and key role, strict requirements are placed on its manufacturing process. At present, the production methods of aluminum alloy branch shell parts mainly include mechani...
