The invention discloses a flat television face frame and a production method thereof. The production method comprises stripping stainless steel coiled materials into straight line-shaped steel bars according to the size of the flat television face frame; performing stamping on the steel bars after stripping; splicing the four steel bars in a head-to-tail mode and then fixing through welding to form into a planar square frame; and performing flanging on the planar square frame after welding. The production method of the flat television face frame has the advantages of being capable of avoiding a discharging process, accordingly improving the utilization rate of stainless steels and being simple and convenient to perform machining at the same time due to the fact that the stainless steel coiled materials are stripped into the steel bars to replace L-shaped steel sheets and saving large-sized die and equipment costs needed by forming the L-shaped steel sheets from sheet metal blanking due to the fact that L-shaped discharging materials are replaced by bar material splicing.

The present invention relates to a reinforced frame for supporting a display panel, which is made of aluminum alloy-extruded materials. More particularly, a rectangular metal-reinforced frame for supporting a display panel such as for a LCD, PDP, etc. includes: a pair of parallel bar-shaped long frame members (21) which are made of aluminum alloy-extruded materials; a pair of parallel bar-shaped short frame members (22) which are made of aluminum alloy-extruded materials; and protrusions (23) where the long and short frame members contact each other (21)(22) and the body of the display panel is raised more than a non-contact part therebetween. In a pair of bar-shaped short frame members, both end portions of the short frame members are placed over both end portions of the long frame members in a rectangular shape, and then joined by rotational friction welding.

Reinforced frame for display panel using aluminum alloy-extruded materials

A reinforcing frame for a display panel using Al-alloy extrusion material and a manufacturing method thereof are provided to minimize loss of raw material abandoned during press processing of reinforcing frame manufacturing processes by using the Al-alloy extrusion material, thereby reducing costs and achieving light weight of the display panel. A reinforcing frame(2) for a display panel using Al-alloy extrusion material comprises a couple of bar type long frame members(21) and a couple of bar type short frame members(22). The long frame members are the Al-alloy extrusion material, and parallel to each other. The short frame members the Al-alloy extrusion material. Both ends of the short frame members are closely contacted with both ends of the same side of the two long frame members in a square frame shape, and coupled through rotation friction welding. The short frame members are parallel to each other.
