Embodiment 1

[0032] A kind of copper tape production process that is used for new energy vehicle connector of this embodiment, it is the H02 specification H65 brass strip of 0.8mm thickness, H02 specification represents the semi-hard state of copper strip, and its Vickers hardness is 100-130 , H65 composition is: copper Cu: 63.5 ~ 68.0; zinc Zn: balance; lead Pb: ≤0.03; lead Pb: ≤0.03; boron P: ≤0.01; : ≤0.002, its performance is between H68 and H62, the price is cheaper than H68, it can withstand cold and hot pressure processing well, and it has a tendency of corrosion and cracking. A kind of copper strip production technique its step is as follows:

[0033] (1) Melting ingot; (2) Face milling; (3) Hot rolling; (4) Rough rolling; (5) Primary annealing; (6) Primary cleaning; (7) Intermediate rolling; (8) Secondary annealing; (9) Second cleaning; (10) Middle finishing rolling; (11) Three times annealing; (12) Three cleanings; (13) Finish rolling; (14) Four cleanings; (15) Leveling.

Abstract

The invention discloses a copper belt production technology for a new energy automobile connector, and belongs to the technical field of the copper plate belt production technology. The technology comprises the first step of cast ingot smelting, the second step of face milling, the third step of hot rolling, the fourth step of rough rolling, the fifth step of one-time annealing, the sixth step of one-time cleaning, the seventh step of intermediate rolling, the eighth step of two-time annealing, the ninth step of two-time cleaning, the tenth step of intermediate rolling, the eleventh step of three-time annealing, the twelfth step of three-time cleaning, the thirteenth step of finish rolling, the fourteenth step of four-time cleaning and the fifteenth step of leveling, wherein in the fourth step of rough rolling, after rough rolling, the regulated thickness of a belt roll is 2.5 mm. By means of the technical scheme, the copper belt annealing technology quality and the copper belt surface quality can be improved, and therefore the workshop cost can be reduced, and the productive profit can be increased.

Description

technical field [0001] The invention relates to the technical field of copper strip production technology, and more specifically, relates to a copper strip production technique for new energy vehicle connectors. Background technique [0002] Today, when resources and energy are in short supply and environmental problems are increasingly severe, building a resource-saving and environment-friendly society has become a common goal of national and even global development. New energy vehicles are an important product of this development goal. With the guidance of national policies, new energy vehicles with low energy consumption, low emissions and low pollution have gradually entered people's field of vision. New energy vehicles need to use a large number of connectors to achieve electrical transmission and control. Automotive connectors are mainly composed of four parts: contacts, housings, insulators and accessories. Contacts are the core parts of automotive connectors to compl...
