Abstract

一种PCD复合片的刀轮，由PCD复合片构成，PCD层厚度在刀轮总厚度的2/3以上。PCD复合片中的PCD面加工很简单，以PCD面为基准面再加工硬质合金面也非常简单，且易保证很高的加工精度。这种PCD刀轮的使用性能与纯PCD刀轮一样，也同样可以实现很高的使用寿命，是目前国际最优质硬质合金刀轮使用寿命的3－10倍。采用这种复合片材料来制造刀轮可以实现低成本大批量制作。经过大批量的制造测算，其制造成本仅为目前高档次刀轮售价的50％左右。以如此低的成本而又如此高的性能，其市场应用必然极为广泛。用这种刀轮来代替目前市场常用的硬质合金刀轮及纯PCD刀轮，必然可以大幅降低客户的生产成本，提高客户的加工效率。

Description

一种PCD复合片的刀轮
技术领域
本实用新型涉及一种PCD(聚晶金刚石，英文polycrystalline diamond，通常缩写为PCD)复合片的刀轮，属于工具技术领域，主要用于玻璃切割及陶瓷切割。
背景技术
现有的刀轮的为优质硬质合金刀轮，其结构为整体采用硬质合金材料，使用寿命较低。也有整体采用PCD材料，使用寿命较长、性能优越，但高品质的刀轮通常要求各项尺寸的公差都很小，例如厚度尺寸要求±3微米甚至更高，而PCD加工非常困难，故制造成本很高。
发明内容
为了克服现有技术结构的不足，本实用新型提供一种PCD复合片的刀轮。
本实用新型解决其技术问题所采用的技术方案是：一种PCD复合片的刀轮，由PCD复合片构成，PCD层厚度在刀轮总厚度的2/3以上。
本实用新型的有益效果：PCD复合片中的PCD面加工很简单，以PCD面为基准面再加工硬质合金面也非常简单，且易保证很高的加工精度。
这种PCD复合片刀轮的使用性能与纯PCD刀轮一样，也同样可以实现很高的使用寿命，是目前国际最优质硬质合金刀轮使用寿命的3-10倍。
采用这种复合片材料来制造刀轮可以实现低成本大批量制作。经过大批量的制造测算，其制造成本仅为目前高档次合金刀轮售价的50％左右。
以如此低的成本而又如此高的性能，必然可以大幅降低客户的生产成本，提高客户的加工效率。其市场应用也必然极为广泛。
附图说明
图1为本实用新型的两层结构示意图。
图2为本实用新型示意图。
下面结合附图和实施例对本实用新型进一步说明。
具体实施方式
实施例1：如图1、图2所示，一种PCD复合片的刀轮，由PCD复合片构成，PCD层厚度在总厚度的2/3以上，PCD层1和硬质合金层2构成PCD复合片刀轮本体，硬质合金层2在PCD层1的一侧并紧密连接，有孔4穿过PCD层1和硬质合金层2并位于PCD复合片刀轮本体的中心。
实施例2：如图2所示，其结构同实施例1，在刀轮的外圆刀尖上有与孔4同心的圆3，圆3的宽度的左侧与左侧刀尖斜面相交，圆3的宽度的右侧与右侧刀尖斜面相交。
圆3使得刀轮抗冲击，刀尖不易磨损，寿命长。

Claims (3)
