Abstract
本发明属于轴瓦加工领域,具体涉及一种铜基轴瓦的制备工艺,包括制备钢背层、铺设合金粉、烧结初轧、精烧、较平和检测包装步骤,该工艺生产的轴瓦具有加工工艺成本低,加工出的轴瓦抗疲劳强度高的特点。
Description
技术领域
本发明属于轴瓦加工领域,尤其指一种铜基轴瓦的制备工艺。
背景技术
传统轴瓦一般采用钢背+合金层+镀层三层结构,其中合金层材料以铝为主的称为铝基材料、以铜为主称为铜基材料。铜基轴瓦的加工一般以烧结为主要工艺,但随着发动机功率的不断攀升、超载及操作方面的因素,一直存在且越来越明显的另一个问题是,合金层与钢背层的结合不够牢固,轴瓦在使用过程中合金层的剥落现象越来越突出,从而造成发动机抱轴烧瓦现象。目前针对这一问题的解决方式常见的技术如CN 101629601B公开了一种高分子耐磨轴瓦,其核心其实是依赖聚酰胺酰亚胺复合聚酯材料的自身粘合性和耐磨性等物理化学性能在轴瓦使用中的应用,侧重于配方设计和制备。
发明内容
本发明旨在提供一种铜基轴瓦的制备工艺,从结构和工艺两方面克服轴瓦合金层易剥落的现象,本发明的技术方案包括,
1、 制备钢背层,在钢背层上开设若干通孔,所述通孔内放置有钢钉,
2、 在制备好的钢背层上铺设合金粉,所述合金粉为混合均匀的2%的镍、1.5%的锡、0.6%的磷、余为铜,
3、烧结,将已铺粉的钢背层进行烧结,烧结参数为温度1045度,时间30分钟,
4、初轧,对烧结后的板材进行初轧,初轧变形量83%,
5、精烧,对初轧后的板材进行精烧,烧结参数:温度1010度,时间30分钟,
6、精轧,对烧结后的板材进行精轧,精轧变形量3%,
7、较平,
8、检测包装。
本发明技术方案相比较现有技术有以下优点,通过构造的改进使合金层与钢背层的结合更加牢固,现有技术通过对合金层材料组分的不断探索试图加强这种结合牢度,可受材料本身性能这种结合仍不能满足发动机轴瓦越来越高的要求。本发明通过对钢背层制备的改进,相当于通过螺栓形式将合金层固定在钢背层上,再经过两次轧制和烧结,使钢背和合金层结合程度更高,轴瓦合金层抗疲劳性能有显著提高,不易脱落。
说明书附图
图1为本发明分层结构参考示意图。
具体实施方式
参照图1所示,一种铜基轴瓦的制备工艺,包括,
1、 制备钢背层,在钢背层1上开设若干通孔,所述通孔内放置有钢钉2,
2、 在制备好的钢背层1上铺设合金粉3,所述合金粉3为混合均匀的2%的镍、1.5%的锡、0.6%的磷、余为铜,
3、烧结,将已铺粉的钢背层1进行烧结,烧结参数为温度1045度,时间30分钟,
4、初轧,对烧结后的板材进行初轧,初轧变形量83%,
5、精烧,对初轧后的板材进行精烧,烧结参数:温度1010度,时间30分钟,
6、精轧,对烧结后的板材进行精轧,精轧变形量3%,
7、较平,
8、检测包装。
