摘要
为解决转向架防腐厚涂层固化问题,依照相关标准和规范,对防腐涂层厚度作出规定,要求总干膜厚度为250μm左右,并对腻子的刮涂重量限制在5~8 kg以内,对转向架的焊接质量提出了更高的要求;分析了转向架防腐厚涂层涂覆、固化工艺以及高速动车转向架专用防腐涂料的最优组合,有利于涂层强辐射固化工艺设计和工艺过程安排;短波辐射加热器为涂层固化的关键部件,采用抛物面与椭圆面组合的特殊结构设计,更有利于深层定向辐射,使防腐涂层的底部溶剂迅速挥发,增强了涂层的附着力,尤其适合轮对轴的厚涂层固化要求;强辐射固化设备参数化设计及虚拟装配,为不同厂家相关产品防腐涂层固化设备设计提供了快捷便利的参考。
In order to solve the problem on bogie anti-corrosive thick coating curing,then the thickness of anti-corrosion coating 250 μm or/about and the thickness of general dry film and 5~8 kg limited of scraping putty weight were required in accordance with relevant standards and specifications,as requlated with anti-corrosive thickness.Therefore,the still high quality on welding bogie was proposed and reguested.Analysis of bogie anti-corrosion thick coating paint,curing technology and optimal combination of special anti-corrosive coatings on the surface of high speed bogie was made,which is favourable for tech-equipment and process arrangement and coat infense radiation curing.Short-wave radiation heater is the key component of the coating to be cured.A special combination of structural design by elliptical surface and parabolic surface was adopted.It is more conducive to deep directional radiation which makes the solvent in the bottom of anti-corrosive coating evaporate quickly as a result of strong coating adhesion.Therefore short-wave radiation heater is more suitable for curing the thick coating of wheel axis.Intense radiation curing equipment,parametric design and its virtual assembly provide quick and easy reference in design of anti-corrosive coating curing equipment to produce other relevant products for different manufactures being concerned.
