알루미늄 압출 각재의 불규칙 휨 개선에 관한 연구 A Study on the Improvement of Irregular Bending of Aluminum Extruded Square Bars
pp.166-173
With the current increase in national income, consumers are favoring expensive home appliances. Many aluminum parts are used to improve the appearance of TV products. However, many losses are incurred due to production defects. There are many flaws in the bending process. This study studied the improvement of bending defects during fault handling. The material used is an aluminum alloy (6063), and the product is a serrated component on the surface of an aluminum part. After the bending process, it was identified how the sawtooth area was twisted. Then, while bending, experimented to find the main cause of the defect. The study tried to find maximum effectiveness with a minimum experiment using 6 sigma techniques. The experiment showed that there were many defects depending on the bending speed of the part and the distance it was fixed. The experiment used a method of finding optimal conditions by combining variables from each item. As a result, the failure was minimized when the distance between the two axes was maintained at 4.5-5mm and the bending speed was maintained at 15mm/sec. The component fixation force has a fixed hook in the middle of the product, and therefore it is found that changes in the amount of byte for the fixed part do not result in significant improvements in the defect.
