Abstract

The invention discloses a production method of an aluminum alloy base material used for LED (light emitting diode) television sets. During batching, on the basis of existing manufacturing components of 3104 aluminum alloy, the method readjusts the mass fractions of each chemical component in aluminum alloy raw materials, and adopts a box-type furnace annealing process during annealing treatment, as well as adjusts an annealing system so as to make the prepared aluminum alloy base material have stable mechanical properties and a surface with a uniform color. Meanwhile, the strength and elongation percentage of the aluminum alloy base material are improved. The method of the invention employs a unique stretching, bending and straightening technology while straightening an aluminum alloy finished product so as to guarantee the flatness of the aluminum alloy base material and stabilize its yield tensile ratio, thus guaranteeing that the aluminum alloy base material is difficult to crack during punching.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing and manufacturing, in particular to a method for producing an aluminum alloy base material for a light emitting diode (LED, Light Emitting Diode) TV set. Background technique [0002] In recent years, Flat Panel Display (FPD) has developed rapidly. At present, there are mainly two types of flat panel TVs that are dominant in the market: one is plasma TV, and the other is LCD TV. LED TV is a kind of LCD TV. At present, the market has a high degree of recognition for LED TV, and the market demand is relatively large. At present, LED TV has more than 70% of the market share in the primary and secondary markets. [0003] The display screen is one of the core components of the LED TV. The support and protection of the display screen is mainly realized through its back plate, and the back plate is the only heat dissipation element of the display screen. At the same time, various circui...
