Description

technical field [0001] The invention relates to the technical field of magnesium-based wires, in particular to an automatic wire drawing device for manufacturing magnesium-based wires. Background technique [0002] At present, magnesium-based metal wires are used in various fields. Due to the good electrical conductivity of magnesium-based metal wires, installing magnesium mesh in building materials such as large-scale instruments and equipment, computer rooms, and TV towers can be used for electromagnetic protection, and its electronic shielding properties are also used as wires and shielding meshes in the aerospace field. The density and elastic modulus of magnesium are very close to the natural bone of the human body, which can avoid the stress shielding effect, and because magnesium can be degraded in the body, and magnesium is an essential metal nutrient element for the human body, it participates in almost all physiological and biochemical reactions in the body, so it ...

AI Technical Summary

Problems solved by technology

Based on the multiple applications of the above occasions, it is necessary to manufacture an efficient and continuous automatic production of magnesium wire. The tensile strength of magnesium wire is much lower than that of steel wire and it is difficult to deform during the drawing process, so the speed of wire drawing needs to be strictly controlled; at the same time After many times of drawing, the work hardening is obvious. In order to prevent the fracture due to stress concentration, the mold needs to be heated at the deformed part of the magnesium wire, and appropriate annealing and softening treatment is also required in the middle, and because the magnesium wire is very easy to oxidize, so for magnesium wire Anti-oxidation treatment is very important. Ordinary wire drawing machines use galvanic heating. This heating method cannot provide anti-oxidation requirements, and magnesium wire is easy to burn, so it is best to isolate the air after heating.

At present, there is no related equipment for automatic wire drawing machines on the market to solve the above problems, so it is necessary to invent such a device that can realize this series of functions
