Description
技术领域
本发明涉及金刚石刀齿技术领域，特别涉及一种高强金刚石刀齿的制造方法。
背景技术
市场上在制造金刚石刀齿的过程中，需要一些固结切削元件制作金刚石的粘结剂，粘结剂分为金属粘结剂、树脂粘结剂、陶瓷粘结剂等，其中金属粘结剂是制作金刚石工具的主要成分。现有生产工艺是以铜、钴、镍、锡等金属粉加入人造金刚石混合，经高温(800℃以上)热压烧结冷却后制成金刚石刀齿，再将金刚石刀齿焊接于钢制钻管上制成薄壁金刚石钻头，金属粉的配制是为了提高骨架材料的密度通常采用混合粒度，现有技术中的金刚石刀齿制成的钻头的出钻效果不好，而且强度低、耐磨性差、使用寿命较短。为此，我们提出一种高强金刚石刀齿的制造方法。
发明内容
本发明的主要目的在于提供一种高强金刚石刀齿的制造方法，可以有效解决背景技术中的问题。
为实现上述目的，本发明采取的技术方案为：
一种高强金刚石刀齿的制造方法，包括以下步骤：用骨架材料与粘接金属进行胎体料配制、配制后进行混料、混料完成后装料进行热压成型、热压成型后进行冷却、冷却后进行机械加工，其中所述胎体料配制过程中的粉料包括Cu25％、Fe20％、Sn4％、Ni18％、Mn3％、WC15％和Co15％，在混料过程中加入重量为胎体料总重量的8％的金刚石，所述金刚石采用50％的35/40目的金刚石和50％的45/50目的金刚石。
与现有技术相比，本发明具有如下有益效果：通过添加Sn粉可改善黏结金属对金刚石的湿润性，有效降低合金熔点，改善粉料压制性能，Ni粉可强化胎体力学性能，并抑制低熔点金属流失，Mn粉可起到脱氧的效果，WC粉导热率高，热膨胀系数与金刚石接近，具有较高的弹性模量和硬度，Co粉可改善铜合金对WC的湿润性，提高铜合金的强度和韧性，本发明制造的金刚石刀齿强度高、耐磨性好、使用寿命长。
