Research On The Elastic Energy Of Daily Ceramic Clay And Optimization Of Rolling Forming Process

Roll forming is one of the most important forming methods in the production of daily ceramics.The level of forming quality determines the final qualification rate of the product,but the adjustment of rolling forming process parameters only depends on the experience of the operator,and lacks in-depth and systematic research.In this paper,the mechanical properties and friction properties of ceramic clay are first studied,and its mechanical properties and friction properties under different moisture content are obtained.ABABQUS software was used to study the effect of the resilience energy of ceramic mud in the three deformation states of "horizontal pressing","plane rolling" and "curved rolling".It can be concluded that the rebound rate of the ceramic mud in the three deformation states has(1)under the working moisture content,the rebound rate of the ceramic mud is inversely proportional to its own moisture content;(2)With the increase of the pressure of the sludge,the springback rate of the ceramic mud gradually increases;(3)The springback rate of ceramic clay will gradually decrease with the increase of rolling times.Secondly,the springback measurement device of ceramic mud is used to verify the springback rate of ceramic mud under curved rolling.The results show that the average relative error between the experimental results and the simulation results does not exceed3.01%.Then,the one-way coupling model of "roller-ceramic mud-mold" is simulated and analyzed,and the extension law of ceramic mud in the rolling forming process is obtained.According to the actual production situation,the "average equivalent force at the bottom of the mud" was determined as the evaluation index of the quality of rolling forming products.Finally,through the orthogonal test of the rolling forming process parameters and the range analysis of the experimental data,it is concluded that the roller diameter of 22 mm,the spindle speed is 30r/s,the rolling time is 3,the speed ratio is 0.8,and the downward pressure is 1.5 mm,and the average residual stress at the bottom of the ceramic mud is only 0.019321 Mpa under the process parameter group.
