Method for processing magnesium alloy plate

Abstract

The invention discloses a method for processing a magnesium alloy plate. Heating temperatures of a terrace die, a die and a blank holder and the magnesium alloy plate are preset reasonably, and an insulation process is set after heating is ended. In addition, a proper lubricating manner is adopted in the invention. Meanwhile, the method can be used for more conveniently measuring the temperatures of all parts through arrangement of a temperature sensor. The invention is especially suitable for the processing of the magnesium alloy plate described in the specification of the invention, the magnesium alloy plate in the specification of the invention is processed through the method disclosed by the invention, better forming effect can be achieved, and tension fracture and corrugation of a formed part can be avoided. The magnesium alloy plate is processed through the method disclosed by the invention, the plasticity of the plate can be provided, the elongation is increased, and the tensile strength is not greatly reduced.

Description

technical field [0001] The invention relates to a method for processing a plate, in particular to a method for processing a magnesium alloy plate. Background technique [0002] Magnesium alloy has a series of advantages such as low density, high specific strength, high specific stiffness, good vibration damping, electromagnetic shielding, etc. It has important application value in the fields of automobile industry, communication electronics, aerospace, weapon industry, etc. Application prospects. More than 70% of the magnesium alloy structural materials in actual use are cast magnesium alloys, while deformed magnesium alloys are limited. The reason is that the magnesium alloy has a close-packed hexagonal structure, which determines that its slip system is small, which affects the plastic processing performance at room temperature. However, the performance of cast magnesium alloys cannot be compared with wrought magnesium alloys. Therefore, it is particularly important to s...

More than 70% of the magnesium alloy structural materials in actual use are cast magnesium alloys, while deformed magnesium alloys are limited

The reason is that the magnesium alloy has a close-packed hexagonal structure, which determines that its slip system is small, which affects the plastic processing performance at room temperature.

However, the performance of cast magnesium alloys cannot be compared with wrought magnesium alloys. Therefore, it is particularly important to study the mechanism of magnesium composite plastic forming, vigorously develop new plastic forming processes, and promote the industrial application of wrought magnesium alloys.

Sheet forming plays an important role in modern product manufacturing, but the research on stamping forming technology and formability of magnesium alloy sheet is relatively late, and the development is not mature enough to meet the leading role in the industrial production and application of magnesium alloy sheet
