②A型硫化机胶囊沿模具自下而上贴紧胎胚运动,因此在胎胚钢圈部位不易夹气,RIB硫化机胶囊下部与A型的夹持形式基本相似,胶囊填满胎胚的运动形式相似,它继承了A型硫化机避免在胎胚钢圈部位夹气的优点。
③A型硫化机上模的运动轨迹是垂直加平移式,这对提高上下模的对中精度尤其是其重复精度是有利的,同时模具不翻转对提高模具的寿命和精度有利。RIB硫化机的上模运动形式采用垂直加平移式,整个硫化过程中无翻转运动,继承了A型硫化机的这一优点。
④RIB硫化机的胶囊更换时间比A型硫化机囊筒更换时间短。
⑤RIB硫化机的胶囊为半翻转,其折叠程度比A型硫化机少,胶囊使用寿命长。
⑥RIB硫化机用中心机构取代A型硫化机囊筒机构,硫化时硫化介质不进入囊井,取消动力水,同时需充蒸汽的容积减少,这样克服A型能耗高的缺点,节省能源。同时大大减少泄漏点,减少维修量及更利于环境的保护。
⑦A型硫化机装胎机构装在横梁上随横梁运动,增加了运动造成的偏差,不利于保证装胎机构在装胎位置时与中心机构的对中度及其重复精度。桂林橡机厂在新研制1050RIB硫化机中将装胎机构焊接在墙板上,提高装胎机构与中心机构的同轴度及其重复精度。
3.2 RIB轮胎硫化机与B型比较
①胶囊如图1所示,RIB硫化机采用蘑菇形胶囊,圆周膨胀少,B型硫化机采用圆筒形胶囊,圆周膨胀大。RIB硫化机由于胶囊形状更接近轮胎内腔,胶囊的膨胀小,定型时胎胚变形小。同时B型硫化机胶囊填满胎胚是先从胶囊中部开始,而胎胚内气体由中往上下胎圈赶,由于上下环附近模具跑胶孔很少,在胎胚钢圈部位易积压气泡,造成钢圈部位缺胶而可能影响硫化轮胎质量。
