Description

一种耐磨型组合式车轮制造工艺
技术领域
本发明涉及轨道交通领域，具体是一种耐磨型组合式车轮制造工艺。
背景技术
现有的高速轨道列车的速度提升程度较大，轨道交通经长时间运营后，轨道行走面经轻轨列车导向行驶会造成明显磨损痕迹，在现有的大多数轨道列车车轮其采用的是锰合金钢整体轧制，该种车轮在踏面产生大量磨损后，整体必须进行更换报废，其使用寿命不长且大量浪费材料。而普通的组合式车轮其可靠性低，不能满足日益增长的发展需求。
发明内容
本发明旨在提供一种耐磨型组合式车轮制造工艺，以解决上述问题。
为实现上述目的，本发明的技术方案如下：
一种耐磨型组合式车轮制造工艺，其特征在于，包括以下步骤：
a. 选用304不锈钢板材作为坯料，截取并加工出轮毂的粗坯，将粗坯进行固溶处理，保持温度1050 ℃，持续时间15分钟，然后快速冷却；持续时间15分钟，再将轮毂从处理线转入喷涂线进行喷粉，喷粉完成后对轮毂依次固化处理，然后快速冷却，并对其表面进行打磨处理；
b.选取锰合金钢为原料，通过铸造加工出轮箍粗坯，并加热后利用扣环将轮箍固定在轮毂上；
c.在b步骤完成后，对轮箍表面喷涂/滚涂底层漆，底层漆为白刚玉砂粒，使粗糙度达到8~15μm，并干燥30分钟；
d.在c步骤完成后在底层漆表面喷涂/滚涂中涂层漆，所述中涂层漆为脂肪族聚氨酯玻璃鳞片漆，干燥0.5-1.5小时后连续在中涂层漆上喷涂三遍聚氨酯罩光清漆。
进一步地，所述底层漆的涂层厚度为100μm-120μm。
进一步地，所述中涂层漆的涂层厚度为130μm-150μm。
进一步地，所述聚氨酯罩光清漆的涂层厚度为130μm-150μm。
本发明的有益效果在于：本发明采用的涂层体系相比，能在车轮表面形成一层涂装的漆膜，在长期的行走过程中，先是对漆膜进行摩擦，能有效延长车轮的使用寿命，节省经济成本。其次，本发明采用的是组合式车轮，节省经济成本。
具体实施方式
下面结合具体实施例对本发明做进一步说明。
