Description

一种耐磨的圆盘剪
技术领域
本发明涉及一种耐磨的圆盘剪，属于机械设备领域。
背景技术
圆盘剪是切纸质品的工具，在切纸质品的过程中，对切口要求十分严格。目前，圆盘剪使用的材料是普通钢材，因此，在使用的过程中，圆盘剪切面容易出现磨损。
发明内容
针对现有技术的不足之处，本发明提供了一种耐磨的圆盘剪。
一种耐磨的圆盘剪，由中空的圆柱状芯材，和芯材外周的硬质合金耐磨层组成，所述芯材内表面设置有环状凸台。
所述的硬质合金耐磨层上表面为倾斜15°的斜面。
作为优选项，所述硬质合金耐磨层由下述质量百分比的成分组成：Mo:36-46%,Cr:10-15%,W:6-14%,C:7-12%,Si:1-3%,余量为Fe。
作为优选项，所述硬质合金耐磨层是通过熔敷工艺熔敷在芯材上面。
本发明的耐磨的圆盘剪的制备方法，包括如下步骤：
一）、制备药芯焊丝，所述药芯焊丝外皮材料为碳钢或者不锈钢，其余粉末通过混粉机混合1-2小时，作为药芯；整个药芯焊丝的成分为Mo:36-46%,Cr:10-15%,W:6-14%,C:7-12%,Si:1-3%,余量为Fe；所述药芯焊丝直径为2.4mm；
二）、将圆柱状芯材加温至220-250℃，然后将步骤一制备的药芯焊丝通过调节电流堆焊在芯材外周，然后将焊有药芯焊丝的芯材外部包裹保温材料,保温十个小时后即可。
作为优选项，所述步骤二中电流在150-155安培之间。
作为优选项，所述芯材的材料为42＃铬钼。
本发明的有益技术效果：将芯材和新型硬质合金通过熔敷的方式结合在一起，新型硬质合金成分包括成分中的C与CR成分较多，形成M7C3型碳化物，M7C3型碳化物使材料的硬度与耐磨性得到提升，同时W与C形成碳化钨，碳化钨也是材料的硬度与耐磨性得到提升。同时W，Cr，Mo元素分布在基体里面，固溶于基体，增加耐磨性。， Mo元素，在摩擦时生成Mo的氧化物，它们的存在会对接触面有一定的润滑作用，解决了圆盘剪在工作中容易出现的磨损的现象，从而延长了圆盘剪的工作周期，解决了其频繁失效的缺陷，减少了圆盘剪的消耗量，节约了成本。
