西安不锈钢拉丝处理的注意事项

1、拉丝(磨砂):通常在不锈钢表面机械摩擦的方法加工处理后得到表面状态为直线的纹路(也叫磨砂),包括拉丝,和纹,波纹。

加工质量标准:纹路粗细深浅一致均匀,产品每一面的纹路根据设计和施工要求,自然美观,产品的弯位允许有轻微的不影响外观的絮乱纹路。

1拉丝的工艺处理

(1) 不同型号的砂纸所形成的纹路也不一样,砂纸的型号越大,砂粒越细所形成的纹路也就越浅,反之, 砂纸

的型号越小,砂粒越粗所形成的纹路也就越深.因此在工程图面上必须注明砂纸型号.  

(2) 拉丝具有方向性:工程图面上必须注明是直纹还横纹拉丝(用双箭头表示). 

(3) 拉丝工件的拉丝面不能有任何凸起部分,否则会将该凸起部分拉平

   : 一般情况下拉丝后须再作电镀,氧化等处理.:铁材电镀, 铝材氧化.由于拉丝机的缺陷,小工件及工

件上有比较大的孔时,须考虑设计拉丝治具,以避免拉丝后,导致工件质量不佳. 2拉丝机功能及注意事项

 在拉丝前须根据材料的厚度调整拉丝机至适当高度

 输送带速度越慢,研磨得越细,反之越粗.进给深度太大,则工件表面会**,因此每次进给不应太多,应在0.05mm左右

压筒的压力太小,会压不紧工件,工件受滚轮离心力作用被甩出来,压力太大会加大研磨阻力,影响研磨效果拉丝机有效拉丝宽度不超过600mm.如果长度方向大于600mm而宽度方向小于600mm则必须注意拉丝方向,因拉丝方向是沿材料进给方向.
