Description

一种碳钢材料衬套内外管表面处理工艺
技术领域:
本发明涉及汽车零部件加工生产技术领域,具体涉及一种碳钢材料衬套内外管表面处理工艺。
背景技术:
乘用车控制臂衬套典型结构为“内管+橡胶+外管”结构。内管与外管的材料有碳钢、铝材、塑料,碳钢及铝材用得较多。为了提高衬套的静态刚度和疲劳寿命,大多数衬套设计时要求对硫化成型后的衬套外径进行缩径处理(塑料外管衬套因塑料的材料特性不能进行缩径处理),即衬套成品的外管外径要明显小于硫化成型前的外管外径。同时对衬套的外表面要求是不能生锈,对铝材材质的内外管而言,不存在产品生锈的问题,但是对于碳钢材料的内外管而言,却面临着产品表面生锈防护问题。
对碳钢材质内外管的控制臂衬套而言,考虑到对产品的生锈防护,在生产时通常是对内外管表面进行磷化处理,在零件表面生成一层磷化层防护膜,衬套的生产工艺为:内外管除锈、去油、清洗、磷化→内外管涂胶粘剂并烘干→衬套硫化成型→衬套修边→衬套缩径。在以上工艺中,磷化膜的成膜质量很重要,因为在后序的缩径工序中,当外管外径从大变小的过程中,磷化膜在机械挤压的状态下很容易被挤碎,进而导致橡胶与外管内表面之间硫化粘结失效,即外管脱胶。一般情况下,衬套的外径缩小量在1-2mm之间,普通的磷化膜成膜质量能保证在受缩径挤压时磷化膜不被挤碎,但是当衬套的外径缩小量在2.5-3.5mm或更大时,对磷化膜成膜质量要求很高,一旦控制不好,会导致缩径后的衬套外管脱胶失效,变成废品。
发明内容:
本发明所要解决的技术问题在于克服现有的技术缺陷提供一种方法合理、操作方便、处理便捷的一种碳钢材料衬套内外管表面处理工艺。
本发明所要解决的技术问题采用以下的技术方案来实现:
一种碳钢材料衬套内外管表面处理工艺,其特征在于:包括以下步骤,
步骤一、内外管除锈:将需要除锈的材料放入浸泡箱中,在24-30℃的室温中向浸泡箱中加满浓盐酸,浸泡时间720-1200秒,然后捞出、自然滤干;
步骤二、去油:将滤干后的材料放入箱中,加入脱脂合剂,转动翻滚120-180秒,温度为80-100℃,脱脂合剂中工业用水:脱脂剂的体积比的比例为50:1,工业用水PH值为7-8;
步骤三、去油后清洗:将去油后的材料取出,然后放入清洗箱中,加入PH值为7-8、温度25-31℃的工业用水,翻滚清洗60-90秒,然后取出、自然滤干;
步骤四、喷砂处理:将滤干后的材料放入喷砂机中,使用直径为0.6mm的不锈钢丸进行喷砂处理,时间为480-600秒;
步骤五、涂胶粘剂并烘干:将处理后的材料均匀的涂上胶粘剂,使用100-120℃的热风烘干150-180秒;
步骤六、成型处理:按照常规的方式将材料成型、修边以及缩径;
步骤七、磷化:将成型后的材料用PH值为1-2.5、温度为60-70℃的磷化合剂来进行磷化处理,磷化合剂包含体积比工业用水:磷化液:促进剂为9:1:0.005;
步骤八、磷化后的清洗:将磷化后的材料取出,然后放入清洗箱中,加入PH值为7-8、温度25-31℃的工业用水,翻滚清洗60-90秒,然后取出;
步骤九、磷化后烘干:在100-120℃的烘干箱中进行360-480秒的高温烘干;
