1免烧砌块成型机控制系统设计摘要：随着我国的农耕面积不断减少导致农作物产量持续下降，这是由于一些传统制砖厂大肆把自然土壤当做烧结砖瓦的原材料进行生产，严重破坏了土壤结构，导致农村可耕种土壤面积大大减少。传统的砖在制作过程中都要有加热的过程，一般是焙烧或是蒸汽加热，在这种情况下，砌块进入人们的视野中，砌块一般都是预制的，不需要加热，类似于混凝土，原料按配合比经下料、搅拌、浇捣、养护后定型，需要一定时间，因此免烧砌块成型机应运而生。所以本文研究并设计了免烧砌块成型机及其控制系统，并具体介绍其机械结构、工作过程及电气和液压控制原理。该方案利用电气、液压联合驱动和控制，使得成型机结构大为简化，控制更加简便。关键词：免烧砌块；成型机；PLC控制系统Designofcontrolsystemfornon-burningblockformingmachineAbstract:AsChina'sfarmingarealeadingtodecliningcropyieldscontinuedtodecline,whichisduetosometraditionalbrickfactoriestonaturalsoilwantonlyfiredbrickandtileasarawmaterialforproduction,severelydamagedthesoilstructure,resultingintheruralareaofarablesoilisgreatlyreduced.Traditionalbrickintheproductionprocessmusthavetheheatingprocessisgenerallycalcinedorheatedsteam,inwhichcase,blockintoview,theblocksaregenerallyprefabricated,withoutheating,similartoconcrete,arawmaterialfeedthroughaccordingtothemixingratio,stirring,pouring,shapingaftercuring,itwilltakesometime,andthereforeunburnedblockmakingmachinecameintobeing.Therefore,thispaperstudiedanddesignedunburnedblockmakingmachinecontrolsystem，Italsointroducesitsmechanicalstructure,workingprocessandelectricalandhydrauliccontrolprinciples.Theschemeutilizeselectricandhydrauliccombineddriveandcontrol,whichgreatlysimplifiesthestructureofthemoldingmachineandmakescontroleasier.Keywords:Non-burningblock;Formingmachine;PLCcontrolsystem目录2摘要...............................................................................................................................1Abstract........................................................................................................................1第一章绪论.................................................................................................................31.1课题研究的背景和意义..........................................................................................31.2现状及发展趋势......................................................................................................41.3本课题设计内容......................................................................................................5第二章免烧砌块成型机的设计..................................................................................52.1免烧砌块成型机的组成..........................................................................................52.1.1主要部件的设计...........................................................................................52.1.2各部件的功能...............................................................................................62.2免烧砌块成型机的工作过程..................................................................................62.3免烧砌块成型机的电气、液压控制原理..............................................................72.4系统的特点..............................................................................................................72.5通过Pro/E对整机进行三维建模...........................................................................8第三章控制系统的设计......
