    摘要:

    液壓成型機(jī)模具錐角是影響成型的關(guān)鍵參數(shù)，為降低壓縮過(guò)程中的摩擦力、減少消耗的壓縮能、提高成型燃料的成型密度和成型品質(zhì)，運(yùn)用ANSYS參數(shù)化語(yǔ)言，對(duì)液壓成型機(jī)模具錐角進(jìn)行優(yōu)化分析。研究了模具錐角值與應(yīng)力分布關(guān)系、模具不同錐角時(shí)摩擦力與位移關(guān)系，得出錐角與應(yīng)力分布呈二次拋物線形式。研究結(jié)果表明：模具錐角最佳取值范圍為5.5°～6.0°。經(jīng)試驗(yàn)，錐角在此范圍內(nèi)取值，出模后的成型燃料松弛密度增大，耐久性增加，成型密度和成型品質(zhì)提高。

    Abstract:

    Mold cone angle is an important parameter. The simulation of the main molding stage of hydraulic briquetting machine was carried out with the finite element software ANSYS, in which the special ANSYS parametric design language was used to optimize analysis the mold cone angle of hydraulic briquetting press. The relationship between mold cone angle and equivalent stress was studied, along with the relationship between the friction stress and displacement in different mold cone angle values. The result indicated the best range of mold cone angle of 5.5°～6.0° is obtained, in which, the simulation results are approximately in accordance with the measured values. Furthermore, the briquette block has a good density, and quality, and is suitable for storage and transportation.
