Abstract:

 Stenter clip as an important part of a clamping fabric in a printing and dyeing industry, its structure form and material performance directly affects the effect of clamping fabric. Analyzed the heated situation of clip, established clip model, and determined the clip suffered load, then did the heat - structure coupling analysis on the clip using the ANSYS software. Obtain the transient temperature field and stress field distribution overall clip, and with the increase of heating time, clip reach steady state in about 12000 seconds. Get the different thermal expansion and the difference value of thermal expansion on the blade, gap shape between blade and baseplate, and thermal stress between shaft and hole under different fit between shaft and hole, which provide the basis for the choice of the fit modes of shaft and hole. For the main body of different material, get the different difference value of thermal expansion on the blade, which provides the evidence for the selection of main body’s materials. Analyze the factors of the thermal deformation on the blade, provide the basis for grinding blade shape.

Key words: stenter clip, hot-structure ciupling, temperaturefield, fit modes
