specific Embodiment approach 1

[0008] Specific implementation mode one: the copper wire softening treatment process of the present embodiment, selects Y 2 state copper wire; the selected Y 2 Clean the state copper wire and dry it naturally; then place the cleaned and dried copper wire in a vacuum heat treatment furnace for heat treatment. Cool with inert gas, cool to below 43°C and leave the furnace.

specific Embodiment approach 2

[0009] Specific Embodiment 2: This embodiment differs from Specific Embodiment 1 in that: the heating method adopts atmosphere convection heating.

specific Embodiment approach 3

[0010] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the rate of heating to 270° C. to 280° C. is 7° C. to 12° C. / min. Others are the same as in 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...
