차체판넬의 랜싱공법 개발에 관한 연구

Abstract

Making one car usually needs about 20,000 parts. It is known that there are 20,000 components used in a car. In that Automobile Panel which is used for car's body made by Profil making course in Plastic working has enough solidity compared to its weight and it's surface is so superior that it is used widely in Auto Industry. Although Car making press has advantage in mass production and its own cost is little bit cheap, it has weakness that beginning investments cost is expensive and making time is so delayed. Lately cost of raw materials sharply increase by that new method of construction is under developing for reducing loss of materials. In a car, the product made in press making course is so important. Because the product is directly related to safety on side crashing. So high tensile steel plate is mainly used for this product. But high tensile steel plate is hard to make and Spring-Back phenomenon frequently occurs which makes making course difficult. These problem makes increasing productivity difficult. By using Auto-Form Software in this research we apply and analyze lancing method. Results of simulation in study, moderate position and depth of molding can predictable, can mold product without adjustment(which use metal-mold) and can reduce manufacturing duration of metal-mold. So it surely assists to developing Metal method South Korea is world 5th car making country. South Korea's car industries are increasing the market share and treated as a car power. We should know there are many efforts by subcontractor. So these are the time to develop technology and we assume that this research will contribute to thin profil process.
