Biomass Characteristics Analysis of Compression Forming
Based on the analysis of extrusion mechanical model of the process of flat molding extrusion form roller to the material, the relationship between axial compressive stress, radial compressive stress, tangent friction force and the length of die hole is derived, and the theoretical computation formula of radius ratio of roller and flat die is also derived. It shows effects of friction coefficient, die hole radius and Poisson ratio on the degree of saturation pressure. The paper analyses on the stress of roller in one case of radius ratio. The results from the analysis reveal that the stress mainly concentrates on the area near the center of the roller and the inner part closing the center of flat die, which can guide the basic design about the flat molding extrusion.
