Development of a tool for the local application of identification marks on the front panels of special equipment

Abstract

The article is dedicated to the analysis of the problems of manufacturing the local marks on the front panels of special equipment. The article deals with the issues of ensuring the transfer of the coloring material by the instrument. The article investigates the physical processes of capillary interaction of liquid and solid substances at the stages: 1) applying paint to the tool; 2) state of saturation of the instrument with the coloring liquid; 3) applying of paint on a product. For effective staining, it is necessary to concentrate the dye at the end of the instrument. But on a simple tool part flows down the surface and goes beyond the end. It is necessary to stop the flow of a liquid portion over the surface of the instrument and return the paint to the end of the instrument to simplify manipulations. Tool shape model is proposed for the local application of identification marks on the front panels of special equipment. It is proposed to stop the movement of paint on the tool by limiting the area of distribution. Limitation is implemented by forming a reverse trimmed cone at the end of the tool. Gravity returns a portion of paint to the surface of the tool.
