A CNC machining process for the aluminum extruded outer frame of a display device.
For the outer frame of the liquid crystal display made of the above resin, in order to meet the requirements of EMI (radiation prevention), metal partitions are usually built in the frame to reduce radiation. However, the metal partition is usually an aluminum plate, and the weight of the resin outer frame is added, so the overall weight is quite heavy.
As far as the outer frame of the display device is made from the current aluminum base material, the forging method or the aluminum extrusion method can generally be adopted. However, considering the manufacturing cost factor, the forging method has a higher mold cost and a shorter mold life, so it is not suitable. Therefore, at this stage, only the aluminum extrusion method with lower mold cost is more economical for production. Therefore, the utility model proposes an aluminum extruded outer frame of a display device, which is not only economical in terms of manufacturing cost, but also the aluminum material and the frame can directly reduce radiation and meet the requirements of environmental protection and recycling.

The above objective is achieved in this way, an aluminum extruded outer frame of a display device. The four groups of front cover frame bars and the four groups of rear cover frame bars are respectively butt-welded and fixedly formed by processing an array of elongated aluminum frame bars extruded from aluminum materials. Wherein the front cover frame strip is integrally formed with a transverse rib on the inner side of the butt joint;
And the front cover frame strip and the rear cover frame strip are respectively cut at two end faces to form a pair of joint angles. The four groups of front cover frame strips and rear cover frame strips can be connected and assembled in pairs by using the butting corner to form a rectangular front frame body and a rear frame body. The butt joints of the front frame body and the rear frame body are welded by arc welding, so that the front frame body and the rear frame body made of aluminum extrusion can be firmly connected into a rectangular body. Grind and bake the front surface of the front frame body and the rear frame body to form a welding surface to achieve a beautiful and smooth surface without joints. Such an aluminum extruded front frame body or a rear frame body is structured to position the liquid crystal panel on the butting surface to form an aluminum extruded outer frame.

The specific embodiments of the aluminum outer frame of the display are described in detail with the drawings as follows
