Abstract: The present invention relates to a method for providing virtual contents in a virtual space based on a common coordinate system. A base marker and a target marker are detected from initial image data which indicates the initial state of an actual operation object in an actual operation space. The base marker is a marker for identifying a fixed point in the actual operation space. The target marker is a marker for identifying the actual operation object. An initial model matrix of the target marker and a model matrix of the base marker are obtained from the initial image data. The initial model matrix of the target marker expresses the initial position and direction of the target marker in a virtual operation space having a common coordinate system which has the base marker as a reference. The model matrix of the base marker expresses the position and direction of the base marker. A virtual operation object having a three-dimensional model shape of the actual operation object is produced. The obtained model matrix of the base marker is used to obtain a current model matrix of the target marker, which expresses the current position and direction of the target marker. Accordingly, a virtual operation space based on a common coordinate system may be provided to field operators and remote operators.

Title: 스크류 컨베어에 초경합금 적용방법
Inventor: KANG DUCK HE
IPC: C22C29/08
Filed: 2020-10-22
Abstract: 스크류 컨베어는 산업기계의 여러 분야에서 활용되고 있다. 이때 피가공물이 고압력을 받거나 극한 원심력을 받게되면 스크류의 끝에 마모가 발생한다. 그럴 경우 스크류와 외벽에 간격이 넓어져 수율이 떨어지고 정상적인 가동을 할 수 없게 된다. 본 발명에서는 스크류 컨베어의 끝부분에 초경합금(Tungsten Carbide Alloy)를 적용하는 방법이다. 초경합금은 소결법으로 제조한 재질로 경도(Hra 84~94)가 높고 다른 경질 재질보다 강도가 우수하다. 기존의 적용방법은 브레이징(Brazing),볼트 조립식,용사 등이 있지만 크랙,흔들림,경도낮음 등 문제점이 있어 사용에 어려움이 있다. 전통적인 방법인 브레이징 공법은 은납(Ag-Cu)을 600~800도 가열하여 판상의 초경합금과 아답타(스틸금속)에 접합한다. 그러나 냉각되면서 초경합금과 스틸금속의 열팽창계수 차이로 판상의 초경합금에 균열이 발생한다. 본 발명에서는 초경합금을 3각 기계적으로 조립함으로 이런 문제점을 해결하였다. 이 공법은 초경합금에 열이 가해지지 않으며 기계적으로 조립되므로 굽힘의 응력이 발생해도 크랙발생이 없다. 초경합금에 설계된 3각은 아답타에 동일한 형상으로 조립됨으로 흔들림이나 빠지는 문제점도 해결하였다.
