Abstract

The invention relates to a drawing die for an aluminum alloy wire with the high rare earth content. The drawing die comprises a die body provided with a material inlet and a material outlet, and is characterized by further comprising a heating device arranged at the end of the material inlet and a cooling device arranged at the end of the material outlet. By adopting low-power induction heating before drawing and matching with a front-end temperature sensor, temperature stability in the drawing process of the wire can be guaranteed, aluminum alloy is easy to deform in the hot processing process, and finally the wire can reach 1.5mm or less.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy wire production, in particular to a drawing die for aluminum alloy wire with high rare earth content. Background technique [0002] 3D printing molding technology takes additive manufacturing as the idea, integrates advanced technologies such as numerical control, computer, mechanical engineering and material science and technology, and uses dimensionality reduction manufacturing as an advanced technology to realize the forming of three-dimensional originals. The arc forming additive manufacturing technology uses an electric arc as a heat source to melt and deposit metal wires layer by layer to produce a three-dimensional metal blank that is close to the product design size requirements, and with a small amount of mechanical processing, it finally meets the product size design requirements. [0003] Compared with technologies such as laser selective melting (SLM) and laser near forming (LEN...
