Abstract:
This research was conducted in the force in the different location of die hole, briquetting power, the relationship between briquetting fuel density and extrusion pressure, on the basis of analysis about die hole of self-design ringmatrixpress. The research measured strain value on different points of different structural parameters of the mold wall using strain sensor and has calculated the positive pressure, friction force and regularities of distribution using the mechanics transformation. In this research, the function of extrusion force was calculated using MATLAB, the theoretical value of extrusion power was predicted and the strain value of different points of the mold wall were analyzed. The result showed that the largest of the strain in the contact point of feed cavity and into cavity. The stress of this point was the most concentrated. This area was most likely to occur as deformation and contact fatigue, leading to failure of loop die.
