生物质液压成型机的双锥度模具

Abstract

Abstract:

Design a bi-taper mold to instead the single-taper mold of Hydraulic Briquetting Press. Take mechanical analysis to bi-taper mold, and build a finite element model of bi-taper mold based on ANSYS; take compression test for different materials in the same mold. Conclusion: taper α,β,taper length l₁,l₂,preserving length l₃ and outlet diameter affected forming density; through analysis the material(straw) deformation trend and friction distribution during the extrusion process, we got load variation of the material in the mold; different materials in the same mold had same variation during the compression cycle process. Besides, material average pressure and average density also had a certain relationship.

Key words: biomass, bi-taper, mold, finite element simulation
