Abstract

The invention provides a continuous extrusion forming process for a small-square-area brass special-shaped wire, and relates to the field of brass wire machining. The continuous extrusion forming process for the small-square-area brass special-shaped wire sequentially comprises the steps of 1) preheating of a forming die, 2) extrusion forming, 3) exhaust treatment, 4) anti-oxidation cooling, 5) blow-drying treatment, and 6) finished wire coiling. The brass special-shaped wire produced through the continuous extrusion forming process for the small-square-area brass special-shaped wire has the beneficial effects of being free of oil contamination, oxidation and burrs, high in density and the like. Compared with a traditional drawing process, the process has the beneficial effects of being simple in step, high in productivity, small in energy consumption, stable in quality and the like, the production links are reduced, the product quality is improved, and the environment-friendly effectsof energy saving and emission reduction are achieved.

Description

technical field [0001] The invention relates to the field of processing small square brass wire rods, in particular to a continuous extrusion molding process for small square brass special-shaped wire rods. Background technique [0002] The brass wire produced by continuous extrusion has good mechanical properties and good plasticity in hot state. And the wire is softer. Small square brass special-shaped wires have been formed by traditional drawing production technology so far. The process is extremely complicated, which requires multi-process drawing and multiple annealing, and needs to be cleaned. It is very labor-intensive and time-consuming, and the traditional process still has capacity. Low, low yield and unstable quality. Contents of the invention [0003] The invention provides a continuous extrusion molding process for small square brass special-shaped wire rods. The brass special-shaped wires produced by the small square brass special-shaped wire rod continuou...
