Preparation method and device of silicon nitride ceramic bearing ball
The invention relates to the technical field of ceramic materials, in particular to a silicon nitride ceramic bearing ball preparation method and a device thereof.The preparation method comprises the steps that 1, silicon nitride powder, sintering aid powder, a binder and water are put into a mixing device to be mixed, and feed is obtained; 2, the feed is put into an extrusion forming machine, and a feed rod is obtained through extrusion forming; 3, the feeding rod is put into a rolling machine to be subjected to rolling at a certain temperature, and a bearing ball green body is obtained after discharging; and 4, degreasing and sintering the bearing ball green body to obtain a bearing ball finished product. According to the method, continuous production of the bearing balls can be achieved, automatic production of most steps can be achieved, the working pressure of operators is greatly reduced, the later machining allowance is small, and the production efficiency is effectively improved.
本发明涉及陶瓷材料技术领域，特别涉及一种氮化硅陶瓷轴承球制备方法及其装置，制备方法包括步骤一：将氮化硅粉末、烧结助剂粉末、粘结剂、水投入混炼装置混炼得到喂料；步骤二：将喂料投入挤出成型机内，经挤出成型得到喂料棒；步骤三：将喂料棒投入滚圆机在一定温度下进行滚圆，出料得到轴承球生坯；步骤四：轴承球生坯经脱脂、烧结后得到轴承球成品。本发明方法可以实现轴承球的连续生产，本发明可以实现大部分步骤的自动生产，大幅减少了操作人员的工作压力，之后加工余量较小，有效提高了生产效率。
