Description

一种带有涂层的小型收割机曲柄转盘的制备方法
技术领域
本发明属于农业工具技术领域，尤其涉及一种带有涂层的小型收割机曲柄转盘的制备方法。
背景技术
农作物生产过程中，由于各种原因成本、土地的限制，生产者使用农业机械较少，小型收割机成本小，突破了农村无法进入大型收割机收割的作业瓶颈，推进了收获作业的机械化，缩短了劳动周期，并让人们从繁重的体力劳动解放出来。广泛用于，收割小麦、水稻、青稞、麻类、豆类等农作物。但是现有的曲柄转盘存在好多问题，如放置时间较长后金属制品的特征容易生锈，需要使用者更换曲柄转盘，而达克罗涂层是由片状锌粉、铝粉、含铬的金属盐及粘合剂组成的涂液涂覆于零件表面，经烧结而形成的一种全新结构和性能的防护层，技术人员在此基础上进行了改进和完善。
发明内容
本发明旨在克服现有技术的缺陷，提供一种带有涂层的小型收割机曲柄转盘的制备方法，具有无公害、隔离腐蚀介质性能好，质量稳定的特点。
为了解决上述技术问题，本发明提供以下技术方案：
一种带有涂层的小型收割机曲柄转盘的制备方法，其特征在于，包括如下步骤，前处理，除去零部件曲柄转盘表面的油污、铁和氧化皮杂物；涂覆是用达克罗溶液喷涂或浸渍零部件曲柄转盘，然后再采用离心甩干、自然垂流和/或刷除去多于的达克罗处理液；烘烤是将曲柄转盘基体上的达克罗处理液转变成膜层的过程，在网带式循环热风烘烤炉中进行，整个烘烤过程分为预热区，温度为60～180℃，零部件预热，然后到达固化区的温度为280～330℃；然后清洗、打磨曲柄转盘即可。
进一步，曲柄转盘为圆盘形结构，中心处设置有三个安装孔，曲柄转盘外侧边缘设置有锯齿。
进一步，曲柄转盘的锯齿根部设置有加强肋。
进一步，第二步中，一涂一烘涂层厚度为3～6μm，二涂二烘为6～9μm，三涂三烘为9～12μm。
与现有技术相比较，本发明具有如下的有益效果：
本发明的好处在于，该曲柄转盘涂层具有无公害、无氢脆、优良的耐蚀性、浸透性、耐热性等特点，避免了钢管漏镀，产品质量好，不易生锈。作为农业机械等行业中小零部件的防腐处理，已在世界范围内得到了广泛的应用。
附图说明
图1为本发明带有涂层的小型收割机曲柄转盘的的结构示意图。
具体实施方式
以下结合附图对本发明的优选实施例进行说明，应当理解，此处所描述的优选实施例仅用于说明和解释本发明，并不用于限定本发明。
实施例 如图1所示，一种带有涂层的小型收割机曲柄转盘的制备方法，其特征在于，包括如下步骤，前处理，除去零部件曲柄转盘表面的油污、铁和氧化皮杂物；涂覆是用达克罗溶液喷涂或浸渍零部件曲柄转盘，然后再采用离心甩干、自然垂流和/或刷除去多于的达克罗处理液；烘烤是将曲柄转盘基体上的达克罗处理液转变成膜层的过程，在网带式循环热风烘烤炉中进行，整个烘烤过程分为预热区，温度为60～180℃，零部件预热，然后到达固化区的温度为280～330℃；第二步中，一涂一烘涂层厚度为3～6μm，二涂二烘为6～9μm，三涂三烘为9～12μm。然后清洗、打磨曲柄转盘即可。曲柄转盘1为圆盘形结构，中心处设置有三个安装孔，曲柄转盘外侧边缘设置有锯齿2，曲柄转盘的锯齿根部设置有加强肋。
以上所述仅为说明本发明的实施方式，并不用于限制本发明，对于本领域的技术人员来说，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
