Embodiment 1

[0159] Shell 1, a simple cylindrical casting, with a diameter of 400mm and a height of 700mm, has been mass-produced, with a production quantity of 100 pieces. The specific process flow is as follows:

[0160] Use mold making → mobile sand mixer to mix sand to form cores → box closing → smelting and pouring → mold cooling → falling sand cleaning.

[0161] Figure 4 It is the production process and workshop production flow chart of Example 1.

Embodiment 2

[0163] Shell 2, complex casting with special-shaped curved surface, height 1500mm, new product, the production quantity is 15 pieces. The specific process flow is as follows:

[0164] Using sand 3D printing modeling → box closing → smelting and pouring → mold cooling → falling sand cleaning.

[0165] Figure 5 It is the production process and workshop production flow chart of Example 2.

Embodiment 3

[0167] Shell 3, complex casting, the size is 500mm×800mm×1000mm, the local performance requirements are high, and the production quantity is 10 pieces. The specific process flow is as follows:

[0168] The combination of sand 3D printing and sand CNC cutting is used to manufacture → box closing → smelting and pouring → mold cooling → falling sand cleaning.

Abstract

The invention belongs to the field of casting, particularly relates to the technical field of casting of aluminum / magnesium and other colored aluminum alloys, and particularly relates to an aluminum alloy casting workshop. Multi-variety and small-batch efficient lean manufacturing of high-end equipment castings such as aerospace and the like is achieved, and automatic and intelligent transformation and upgrading of casting are promoted. An aluminum alloy casting workshop comprises a digital mold-free forming area, a molding and core-making area, a mold closing area, a smelting and pouring area, a casting mold cooling area and a shakeout cleaning and regenerating area which are sequentially connected according to the sequence of production procedures, and the shakeout cleaning and regenerating area is connected with the digital mold-free forming area to form a closed-loop assembly line workshop. And a box closing process of the box closing area adopts a flexible clamping plate rapid combined type box-free assembling process. The flexible casting production line for manufacturing complex parts of aerospace high-end equipment is established through optimized partition arrangement, reasonable design and layout of a casting workshop, and automatic and large-scale casting production is achieved through the most suitable, most efficient and most economical production method.

Description

technical field [0001] The invention is suitable for the casting field, especially the technical field of non-ferrous aluminum alloy casting such as aluminum / magnesium, and particularly relates to an aluminum alloy casting workshop and a production scheduling method thereof. Background technique [0002] Different from the large-scale and large-scale production mode of the automobile industry or other civil industries, high-end equipment castings such as aerospace have the characteristics of multi-variety and small-batch production, and it is difficult to realize a batch automatic production line, and its intelligent transformation and upgrading is more difficult. . Due to the high demand for lightweight, short-cycle, and low-cost manufacturing of new-generation products, and the casting of lightweight components for high-end equipment involves multiple processes such as modeling, core making, smelting, pouring, falling sand, cleaning, and inspection, different manufacturing...
