Example Embodiment

[0008] Specific implementation mode 1: In the red copper wire softening process of this embodiment, Y 2 State red copper wire; Y will be selected 2 The copper wire is cleaned and dried naturally; then the cleaned and dried copper wire is placed in a vacuum heat treatment furnace for heat treatment. The heat treatment process parameters: heat up to 270℃-280℃, keep for 43min-47min; then charge the furnace The inert gas is cooled, cooled to below 43°C, and taken out of the furnace.

Example Embodiment

[0009] Specific embodiment two: This embodiment is different from the specific embodiment one in that the heating method adopts atmospheric convection heating.

Example Embodiment

[0010] Specific embodiment three: This embodiment is different from specific embodiment one or two in that the heating rate of heating to 270°C -280°C is 7°C-12°C / min. Others are the same as the first or second embodiment.

Abstract

The invention provides a red copper wire softening treatment process, which relates to a copper wire softening treatment process and aims at solving the problem that a red copper wire purchased according to the existing copper alloy wire material standard cannot meet the rivet forming and Bakelite retainer riveting performance requirements. According to the process, a Y2 state red copper wire is selected; the selected Y2 state red copper wire is cleaned and is naturally dried in the air; then, the cleaned and dried red copper wire is put in a vacuum heat treatment furnace to be subjected to heat treatment according to the following heat treatment parameters: the heating temperature rise value is 270 to 280 DEG C, and the heat insulation time is 43 min to 47 min; and inert gas is inflated into the furnace for cooling; and discharging is performed when the copper wire is cooled to a temperature being 43 DEG C or below. The process provided by the invention is used for softening the red copper wire.

Description

technical field [0001] The invention relates to a copper wire softening treatment process, belonging to the technical field of metal material heat treatment. Background technique [0002] T purchased according to GB / T21652-2008 "Copper and Copper Alloy Wire Rods" 2 For the M-state copper wire under the brand name, when the rivet is made, the rivet "bends" due to the copper wire being too soft, and the bending of the copper wire blocks the rivet forming mold. [0003] T purchased according to GB / T21652-2008 "Copper and Copper Alloy Wire Rods" 2 Y under grade 2 The state copper wire can be processed normally when making rivets, but when using this state rivet to rivet the bakelite cage, the rivet strength is too high and the deformation resistance is strong, so the rivet needs to be riveted many times before it can be formed. Fragmentation of the bakelite cage. [0004] To sum up, the T purchased according to the current copper alloy wire standard 2 The red copper wire un...
