What are the aluminum alloy processing processes? 1. Machine tool processing of aluminum alloy processing technology: 1. Aluminum alloy parts processing, also called CNC Machining, automatic lathe processing. CNC lathe processing, etc.,
(1) Ordinary machine tools use turning, milling, planing, drilling, grinding and other processing mold accessories, and then carry out necessary repairs to the fitter and assemble them into various molds. (2) The precision requirements of mold parts are high, and it is difficult to ensure high processing accuracy only with ordinary machine tools, so precision machine tools are required for processing. (3) In order to make the processing of convex die accessories, especially convex dies, concave die holes and cavities of complex shapes, and the repair work of fitters more automated, it is necessary to use CNC machine tools (such as three-coordinate CNC Milling machines, machining centers, CNC grinding machines, etc.) to process molds. Second, aluminum alloy parts stamping processing: Punching refers to relying on punching machines and dies to pair plates. Laths. Pipes and profiles are subjected to external forces to plastically deform or separate to obtain the molding process of workpieces (stamped parts) of the required shape and size. Stamping parts are with the help of conventional or special stamping machine power, so that the plate is directly deformed in the mold, and then deformed to obtain a certain shape. The production process of product accessories for dimensions and performance. Plate. Molds and equipment are the three major elements of stamping processing. Stamping method is a processing method of cold deformation of metal, so it is also called cold stamping or plate stamping, referred to as stamping. This is a major metal-plastic processing method. 3. Precision parts casting for aluminum alloy processing: It belongs to the precision casting of special castings. The resulting fittings usually do not need to be machined. Such as investment casting, pressure casting, etc. Compared with traditional casting technology, precision casting is a casting method. This method can obtain a more accurate shape and improve the casting accuracy. The more common practice is: first design and manufacture the mold according to the product requirements (leaving a small margin or no margin), casting wax by pouring the wax to obtain the original wax mold, and then repeatedly painting the wax mold, hard shell, dissolving the wax mold inside, in order to dewax and obtain a cavity; shells fired to achieve full strength; Metal materials for pouring; Sand cleaning after hulling; High-precision finished products can be obtained. Heat treatment and cold processing according to product requirements. 4. Powder metallurgy aluminum alloy accessories for aluminum alloy processing: Powder metallurgy is a technology that uses metal powder (sometimes a small amount of non-metallic powder is also added) to mix metal powder to form, sinter, and make materials or products. There are two parts to it, namely: (1) Manufacture of metal powder (including alloy powder, hereinafter collectively referred to as "metal powder"). (2) A metal powder (sometimes a small amount of non-metallic powder is also added) is mixed, shaped and sintered to make a material (called "powder metallurgy material") or product (called "powder metallurgy product"). 5. Injection molding of aluminum alloy processing: The solid powder and organic binder are evenly mixed, and after granulation, it is injected into the mold cavity by injection molding machine in the state of heating and plasticization (~150 °C) to solidify and form, and then the binder in the forming blank is removed by chemical or thermal decomposition, and then the product is obtained by sintering and densification. Compared with the traditional process, it has the characteristics of high precision, uniform organization, excellent performance and low production cost, and its products are widely used in electronic information engineering, biological medical equipment, office equipment, automobiles, machinery, hardware, sports equipment, watch industry, weapons and aerospace and other industrial fields.
