Abstract

The invention discloses a continuous extrusion forming mold for high-strength copper materials. The continuous extrusion forming mold comprises an extrusion forming mold core; the extrusion forming mold core is produced by high-strength mold steel; and the high-strength mold steel consists of the following components in percentage by mass: 1.1% of nickel, 0.55% of carbon, 0.23% of silicon, 0.33% of manganese, 0.4% of chromium, 0.4% of tungsten, 0.03% of molybdenum, 0.06% of vanadium, 0.04% of cobalt, 0.004% of tellurium, 0.002% of neodymium, 0.002% of titanium, 0.006% of boron, and the balance of iron. In the continuous extrusion forming mold for the high-strength copper materials provided by the invention, the selected high-strength mold steel enables the surface of an extrusion forming channel to be not damaged so as to guarantee the surface performances of formed materials.

Description

technical field [0001] The invention relates to the technical field of copper material continuous extrusion molding production, in particular to a high-strength copper material continuous extrusion molding die. Background technique [0002] The continuous extrusion molding technology of copper is one of the extrusion molding technologies. The operation process mainly includes: the prime minister uses electrolytic copper continuous casting to produce bright oxygen-free copper rods of different lengths, decoils and straightens them. , and then sent to the extrusion molding head to form a large length of bright oxygen-free copper profile with specific specifications and shapes through extrusion. The copper continuous extrusion molding die is the core equipment component in the copper continuous extrusion molding technology. The copper continuous extrusion molding die mainly includes the mold core installation cover and the extrusion molding core. The extrusion molding core is m...
