롤 성형 기계의 재제조 과정에서 설계 분석 및 부품의 구조적 안전성 연구

Abstract

First, Re-manufacture the second-hand product saves resources along with preserving waste material. Since garbage is concern and need to recycle. So re-manufacturing knowledge is important. Big companies are interested in producing product from recyclable materials. Whereas re-manufactured products are growing because it has an advantage as eco-friendly and energy-economical product. One of big cause for that is, because those materials are part of nature. That is why, re-manufacturing is defined as a series of processes to re-commercialize end-of-life products and parts as new products. Different re-manufacturing markets already exist throughout the world. However, the size and types of re-manufacturing markets differ according to as per demand and country. In this paper, roll forming machine damage part was studied for restoration technology. likewise rolling motor, gear and chain, feeder with alignment of the machine was studied. The cause of the damage was calculated by the damage recovery process. Additionally repaired the roll forming machine with leaser measurement was applied. The parts of the roll forming machine was examined and replaced for better performance. Next, computer analysis of the rolling parts was studied in this paper. From the roll forming machine, rolling parts are created and assembled in 3D Cad software. All together roller male and female rolling parts are combined. After that, the analysis of the roll-forming parts by applying rotational force. The study involves forming a part, and then computer analysis. Where a material part was fixed as a steel. To be exact, in this study material was stainless steel AISI 304 which is a stronger material. Overall, the use of the maximum force of 10000 newton force to minimum 1 newton is applied to check the stability of the rollers. Altogether four combined rolling part was investigated in two main steps. They are 3D modeling and Stability study. First 2D drawing was converted into three dimensional and real view property was applied. After onwards, that 3D part was computer simulated for stability as following step ; material adjustment, fixing point, applied additional force, mesh study and result evaluation accordingly.
