Embodiment 1

[0026] Present embodiment 1 is used for the copper strip production process of LED support, comprises the following steps:

[0027] (1) Using grade A cathode copper as the raw material, the grade A cathode copper is continuously cast in the smelting device, which is covered with charcoal and graphite phosphorus flakes, and after the casting is completed, it is cooled with cooling circulating water to make the upper lead copper rod;

[0028] In the step (1), the lead rod speed of the traction unit is 450-500mm / min; the cooling circulating water pressure is 0.16-0.18MPa, the pitch is 45mm; the melting temperature is 1156-1160°C.

[0029] The particle size of the charcoal used is 30mm-34mm, the covering thickness is 95mm-100mm, and the covering thickness of the graphite phosphorus sheet is 21mm-27mm.

[0030] In this step (1), the diameter of the copper rod for leading up is 25 mm, and the diameter tolerance is ±0.08 mm.

[0031] (2) Continuously extrude the prepared upward lead...

Embodiment 2

[0038] In Example 2, the cathode copper raw material is directly extruded in the continuous extruder without passing through the copper lead-in rod of the traction unit, and other process steps and process parameters are the same as in Example 1.

Embodiment 3

[0040] In this embodiment 3, the cathode copper raw material passes through the drawing-up copper rod of the traction unit, and then is continuously extruded in a continuous extrusion machine, and is directly subjected to bright annealing without rolling. Other process steps and process parameters are the same as in embodiment 1.

Abstract

The invention relates to a copper belt production process for LED supports comprising following steps: (1) continuous casting is performed on A-grade cathode copper in a smelting device and drawing up copper rods; (2) continuous extrusion is performed on copper rods; (3) multiple times of rolling are performed by means of cold rolling mill according to the thickness of copper belts for LED supports; (4) bright annealing is performed after rolling, then grinding and polishing are performed on the copper belt surface; (5) slitting is performed on rolled copper belts by slitters. The production process is short, efficient and energy saving; compared with traditional production technology, processes such as ingot casting, milling and trimming are saved.

Description

technical field [0001] The invention relates to a copper strip production process for LED brackets. Background technique [0002] With the progress of society and the development of the market, energy saving is becoming more and more important. Due to the advantages of energy saving, environmental protection and long life, LED lights are more and more widely used in fields such as computers, TVs, mobile phones, and car lights. With the promotion of low-carbon economy, LED lights will replace incandescent and fluorescent lamps and enter the ordinary lighting field. LED lamps must have the characteristics of shock resistance, stamping resistance, light effect, power saving and energy saving, long life, and high reliability when used. The LED bracket mainly plays the role of connecting circuit, reflection, welding, etc., and the copper strip for LED bracket needs to have good hardness. , tensile strength, electrical conductivity, thermal conductivity and spectroscopic propert...
