The double strong copper strip production technology comprises the following steps of (1), smelting and ingot casting; (2), hot rolling; (3), milling; (4), rough rolling; (5), once annealing; (6), once cleaning; (7), medium rolling; (8),twice annealing and cleaning; (9), finish rolling; (10), three times annealing and cleaning; (11), finish rolling; (12), four times cleaning; (13), leveling; and (14), examining and delivering; and specified thickness of strip coil after rough rolling is 2.5 mm. According to the technical scheme, brass products can meet the double requirements of tensile strength and elongation index of automobile connector industry.
Description
technical field [0001] The invention relates to the technical field of copper strip production technology, in particular to a double-strength copper strip production technique for automotive connectors. Background technique [0002] The automotive wire harness connector products in automotive connectors have a complex shape in the stamping and forming part of the product, which requires extremely high plasticity of the copper strip material, and the male and female ends of the single-wire piece of the formed connector are engaged and separated (i.e. Insertion force) must meet the requirements of the domestic automotive industry standard "QC / T417-2011", and put forward higher requirements for the strength of copper strip materials. Therefore, for this type of product, the automotive connector industry has proposed "double strength The so-called "double-strength copper strip" is to ensure that the tensile strength of the copper strip material reaches the level of 500MPa, and a...
