Abstract
PURPOSE: To manufacture a titled light plate part made of a thin metallic plate increased in rigidity by an uneven pattern by forming an uneven pattern on a long metallic plate by embossing and after pressing and cutting to a specified length in shearing process, bending the metallic plates one by one.
CONSTITUTION: An uneven pattern 10 of uniform height is made on the whole of both sides of a metallic plates 2 pulled out from a coiler 1 by an embossing machine 3, and after smoothed by a leveler 4, it is supplied to a wide bed press 6. After making specified shearing by the press 6, the metallic plate 2 is cut to a specified length by a gauge table 7. The cut metallic plate is bent little by little by a 14-step roll forming machine, and after passing through a final step roll 11, formed to a thin plate part such as a chassis 12 etc. Thus, weight of plate parts is reduced by the use of a thin metallic plate saving resources, and plate parts for lighting apparatus that restrain generation of vibration and beat of stabilizers and increase heat radiation can be obtained.
