| In view of the serious wear and tear of the biomass solidification molding equipment and the high power consumption of the body,the wear characteristics of the traditional biomass molding equipment were studied.The experimental results of the biomass solidification molding technology and the design of the machine rail slides were borrowed from the past few years.In the experience,a new type of slider plunger type biomass molding machine was designed.That is,the rolling rail block commonly used in the machine tool is used to reduce the friction generated by the mutual movement between the components,the compression of the biomass fuel is realized by the shifting movement of the eccentric wheel,and the unnecessary energy consumption in the biomass solidification molding process is reduced.abrasion.In the design part of the new slider plunger molding machine,combined with the existing research results and mechanical design methods,the equation of motion of the plunger and the size of the key components are determined by geometric analysis.For the first time,the function of the Curve fitting is used.The operating power of the plunger stamping biomass solidification molding equipment was theoretically calculated,and the rated power of the molding machine was obtained without considering the friction loss,which avoids the error caused by the empirical power ratio in the traditional design.And the productivity model and energy consumption model of the plunger are obtained,and then the 3D modeling of the whole machine is completed by Solidworks.On the basis of the modeling of the slider plunger molding machine,static analysis of the main transmission of the slider plunger molding machine was carried out by means of finite element analysis software ANSYS and multi-body dynamics simulation software ADAMS.Analysis and kinetic analysis,and the flexible body of the plunger frame was introduced into ADAMS by ANSYS for dynamic analysis of rigid-flexible coupling,and the following analysis results were obtained:1.Through the kinematics analysis of the main transmission device,the motion characteristic curve of the plunger is extracted,and the velocity and displacement curves are consistent with the results derived from the theoretical calculation.2.Through the results of the dynamic analysis,the contact force between the contact parts of the main transmission device is extracted and the selection of the rolling guide block is determined accordingly.At the same time,because the contact between the components and the friction are set during the dynamic simulation,the actual rated power of the whole machine is 2.1kW,the maximum productivity is 60.48kg/h,and the energy consumption is 34.72kW·h/t,compared to the traditional plunger stamping machine,its energy consumption has doubled.3.Through the dynamic analysis of rigid-flexible coupling,the modal information of the plunger frame is obtained.By comparing the excitation frequency of the input speed,it is shown that the frequencies between the two are not equal,so resonance does not occur.When the ten most stressed points on the plunger frame are extracted,the time when the forming machine is running and the position of the points are found,and these points are found at the same moment,and the transient state of the plunger frame at this moment is extracted.The force cloud diagram finally derived the load file of the plunger frame during the whole movement,which provided the analysis basis for the later fatigue analysis. |
