Abstract

A mechanical model of band sawing saw frame was established according to an analysis of a commonly used saw-frame structure diagram to overcome the problems of low service life, substandard cutting precision and efficiency, and high manufacturing cost caused by the unreasonable design of saw frame. Taking a particular type of sawing machine as an example, stress cycle analysis of the saw blade was carried out according to the mechanical model of the saw frame, and the fatigue analysis model of the most dangerous cross-section point that was most prone to fatigue failure of the saw blade was then established. The fatigue analysis result was used as the basis for the improved design of the saw frame, and the improved detailed saw-frame design parameters were obtained. The results suggested that the saw frame system is much more compact and the saw blade force met the fatigue strength requirements through the improved design. In addition, the service life of the saw blade and the cutting precision were increased. The established mechanical model of the saw frame in this paper is used widely and has high practical application values.

현대 제조 공업이 고효율, 고정밀도와 경제적인 방향으로 발전 하면서 금속을 절단하는 띠톱 기계는 이미 철강, 기계, 자동차, 조선, 석유, 광산, 항공 우주 등 다양한 영역에서 광범위 하게 활용 되고 있다. 하지만 기존의 띠톱 기계들은 경험적으로 설계 되어져 왔으며 따라서 낮은 수명, 톱질 동작 상태에서 낮은 정밀도 및 저효율을 문제와 높은 제조원가 문제를 가지고 있다. 본 논문에서는 띠톱의 역학적 해석을 통해 띠톱 톱대의 설계 파라미터를 개선하는 방법을 제시 하였다. 실제로 빈번하게 사용 되고 있는 띠톱 기계를 모델링 하여 응력 분석, 피로해석을 시행 하였으며 이에 따라 톱대의 상세한 설계 파라미터를 도출 하였다. 그 결과 피로 강도가 피로 요구 사항을 만족 시키고 띠톱 기계의 정밀도와 효율이 크게 향상 되는 것을 확인할 수 있었다.
