Abstract

一种焊接单晶金刚石多功能木工锯片，把金刚石单晶直接焊接在钢基体上，形成主齿和辅助齿，切割中不存在刀头脱落，并可切割带铁钉的材料。由于该产品不外加刀头，切割中完全不存在刀头脱落问题，安全可靠。银铜基焊粉熔点低，流动性好，其合金属于高塑性合金，焊接完成后的缓慢降温冷却过程，使得应力充分释放，避免龟裂。并且由于钛和铬的添加，可在高温中与金刚石表面形成TiC和CrC的膜，保护金刚石不在高温中烧损，而铬与钢基体结合界面表会形成(FexCry)C的薄层，增强金刚石层与钢基体的合金结合强度，对金刚石颗粒形成足够的把持力，以致金刚石在切割工作中不会脱落。

Description

一种焊接单晶金刚石多功能木工锯片
技术领域
本发明涉及金刚石锯片领域，特别地，涉及一种焊接单晶金刚石多功能木工锯片。
背景技术
一般来说木工圆锯片的刀头为硬质合金和PCD金刚石复合片。在锯切中如遇到铁钉等材料会产生崩刃现象。有的会掉齿，产生不安全因素。而单晶金刚石锯片一般用金属粉末烧结制成，用来切割石材、混凝土和陶瓷等材料。
发明内容
本发明目的在于提供一种焊接单晶金刚石多功能木工锯片，以解决技术问题。
一种焊接单晶金刚石多功能木工锯片，由钢基体和增强金刚石层组成；所述的钢基体的成分为：钢45，高速钢，锰钢和高碳钢中的任意一种；所述的增强金刚石层，由焊粉将金刚石单晶焊接在钢基体表面。
优选的，所述的焊粉，包括以下重量百分比的成分：Ag 62-70%，Cu 20-30%，Ti 3-6%，Cr 1-3%。
优选的，所述的金刚石单晶的粒度为35-60目，进一步优选的，所述的金刚石粒度为35/40目或40/45目或45/50目或50/60目。
优选的，所述的金刚石单晶选用中南钻石的金刚石，其中型号2280的质量百分比为25-30%；型号 2290的质量百分比为70-75%。
焊接层高度控制：
为了实现切割中的锋利性，而本发明的产品所用焊粉对金刚石单晶的结合强度足够。焊接层高度应达到金刚石单晶粒度的三分之一。根据不同粒度的金刚石单晶颗粒尺寸，设计相应的焊接高度。具体的焊接高度，请参见表1：
表1：不同粒度的金刚石单晶颗粒尺寸，对应的焊接高度。
粒度 35/40 40/45 45/50 50/60
尺寸mm 0.50 0.42 0.35 0.297
焊接层高度mm 0.16 0.14 0.12 0.10
由于金刚石的实际在基体上的高度误差，实际焊接层高度控制增加10%左右。
所述的木工锯片设计了安装孔，使其可用于角磨机和云石机等电动工具。
本发明具有以下有益效果：本发明的焊接单晶金刚石多功能木工锯片，把金刚石单晶直接焊接在钢基体上，形成主齿和辅助齿，切割中不存在刀头脱落，并可切割带铁钉的材料。由于金刚石是硬度最高的材料，本发明产品可以切割耐磨表层的复合地板，木塑，玻璃纤维和碳纤维的复合材料。由于本发明产品不外加刀头，切割中完全不存在刀头脱落问题，安全可靠。
银铜基焊粉熔点温度低，流动性好。其合金属于高塑性合金，焊接完成后的缓慢降温冷却过程，使得应力充分释放，避免龟裂。钛和铬的添加，可在高温中与金刚石表面形成TiC和CrC的膜，保护金刚石不在高温中烧损，而铬与钢基体结合界面表会形成（FexCry)C的薄层，增强金刚石层与钢基体的合金结合强度，对金刚石颗粒形成足够的把持力，以致金刚石在切割工作中不会脱落。
除了上面所描述的目的、特征和优点之外，本发明还有其它的目的、特征和优点。下面将对本发明作进一步详细的说明。
