Embodiment 1～3

[0023] Using plate stamping technology to form magnesium alloy shell-shaped parts on magnesium alloy (MB2) plates, the specific operations are as follows:

[0024] 1) Install the mold and perform alignment adjustment;

[0025] 2) Check the heating system, preheat the mold to 200-260°C, and the holding time is 1 minute, 1.5 minutes, and 1 minute for each millimeter thickness blank;

[0026] 3) The magnesium alloy sheet is heated to 200-350°C, and the holding time is 1.5 minutes, 1.5 minutes, and 1 minute for each millimeter thickness of the blank;

[0027] 4) Put the magnesium alloy sheet into the mold after using the lubricant; apply the lubricant on the mold and the magnesium alloy sample respectively, the lubricant can be animal oil such as lard, or MnS 2 ;

[0028] 5) Start the stamping and stamping device, the punch starts to move down, and the stamping and forming start. The drawing ratio is controlled within the range of 1.5-3, and the drawing speed is 50-80mm / min; unt...

Abstract

The present invention relates to magnesium alloy preparation technique, in the concrete, it is a processing method of magnesium alloy plate material and its special-purpose hot stamping equipment. Said invention adopts plate stamping technology to form magnesium alloy shell moulded component, and includes the following steps: preheating mould to 200-500 deg.C, heating magnesium alloy plate material to 200-350 deg.C, applying lubricant on plate material and placing said plate material into the mould, controlling drawing ratio in the range of 1.5-3, and its drawing speed is 50-80 mm/min. Said invention can improve the workability of the material, can raise product quality and can raise production efficiency.

Description

technical field [0001] The invention relates to a magnesium alloy preparation technology, in particular to a magnesium alloy plate processing method and a special device. Background technique [0002] Magnesium alloy, as a light weight, strong and tough material with good rigidity, is used in aviation, spacecraft and missiles, which can increase the payload and flight distance, and reduce the service cycle and cost. Therefore, it began to be used in aviation equipment and other fields as early as World War II. For example, magnesium alloy pipe fittings can be used for aircraft inner frame structural parts; in addition, magnesium alloy is very suitable for portable electronic and electrical communication in the 3C industry (Computer, Communication, Consumer Electronics Products, referred to as: 3C) due to its low density and good electromagnetic shielding When equipment, such as mobile phone shells are made of magnesium alloy, electromagnetic waves are only received and sent...
