Problems solved by technology

However, magnesium alloy has a low melting point, high linear expansion coefficient and thermal conductivity, and strong affinity with oxygen and nitrogen. It is easy to form brittle inclusions after welding, which significantly reduces the mechanical properties of the joint. Therefore, the poor welding ability seriously affects the magnesium alloy. Application in structural parts

Embodiment 1

[0058] In this embodiment, the cross section of the body 1a of the first structure 100a and the body 1b of the second structure 100b are the same, and the axes of the first structure 100a and the second structure 100b are assembled perpendicular to each other, wherein the first structure The thickness of the gap between two adjacent connecting flaps 2a of the member 100a is equal to the thickness of the gap between the adjacent two connecting flaps 2b of the second structural member 100b, while the connecting flaps of the first structural member 100a 2a and the connecting flaps 2b of the second structural member 100b are respectively equal in thickness and number.

[0059] like figure 2 As shown, one end of the coupling 200 is connected to the first structural member 100a through the first bolt 300a, and the other end of the coupling 200 is connected to the second structural member 100b through the second bolt 300b, for example, the first bolt 300a and the second bolt 300a 3...

Embodiment 2

[0062] In this embodiment, the body 1a of the first structure 100a and the body 1b of the second structure 100b have different cross-sections, and the axes of the first structure 100a and the second structure 100b are assembled perpendicular to each other. like image 3 As shown in , the thickness of the gap between two adjacent connecting flaps 2a of the first structural member 100a is equal to the thickness of the gap between two adjacent connecting flaps 2b of the second structural member 100b, while the first The connecting flaps 2a of the structural member 100a and the connecting flaps 2b of the second structural member 100b have the same thickness but different numbers.

[0063] like image 3 As shown, one end of the coupling 200 is connected to the first structural member 100a through the first bolt 300a, and the other end of the coupling 200 is connected to the second structural member 100b through the second bolt 300b, for example, the first bolt 300a and the second ...

Embodiment 3

[0066] In this embodiment, the body 1a of the first structure 100a and the body 1b of the second structure 100b have different cross-sections, and the axes of the first structure 100a and the second structure 100b are assembled obliquely to each other. like Figure 4 As shown in , the thickness of the gap between two adjacent connecting flaps 2a of the first structural member 100a is equal to the thickness of the gap between two adjacent connecting flaps 2b of the second structural member 100b, while the first The connecting flaps 2a of the structural member 100a and the connecting flaps 2b of the second structural member 100b have the same thickness but different numbers.

[0067] In this embodiment, one of the first structural member 100a and the second structural member 100b can be pre-cut beveled, for example, as Figure 4 As shown, the end of the second structural member 100b mated with the first structural member 100a is cut with a proper bevel. Then, one end of the co...

Abstract

The invention discloses a magnesium alloy structural part, comprising: a body which has a preset length in a longitudinal direction, and a plurality of coupling flanges which is formed longitudinally along the body and is circumferentially distributed on at least a part of the periphery of the body. According to an embodiment of the invention, the magnesium alloy structural part is characterized by a simple structure, low manufacture cost, and a convenient process, and a relatively complicated magnesium alloy structural apparatus can be easily formed through a mutual combination and connection of respective coupling flanges of a plurality of the magnesium alloy structural parts. The invention also discloses a magnesium alloy structural assembly which is formed through assembly and connection of the above magnesium alloy structural parts.

Description

technical field [0001] The invention relates to the field of structural parts manufacturing and processing, in particular to a magnesium alloy structural part and a magnesium alloy structural component. Background technique [0002] With the world's energy crisis and environmental pollution becoming more and more serious, energy saving and lightweight have become the primary issues of the automobile industry. Magnesium alloy is the lightest structural metal, its weight is 1 / 4 of steel, 1 / 3 lighter than aluminum alloy, and it is easy to process, easy to die-cast, high specific strength and specific stiffness, environment-friendly, Rich resources and other characteristics are of great significance to reducing the weight of the vehicle, reducing fuel consumption, reducing environmental pollution and improving operational performance, and are increasingly favored by the automotive industry. [0003] Due to the low melting point and low heat resistance of magnesium alloys, it al...
