Abstract

本实用新型硬质复合工具,特别适用于切削、磨 削陶瓷、玻璃、塑料及金属材料。具有金属基体,金属 基体切削刃部位包容有复合合金层,构成切削、磨削 刃。复合合金层由金属粉末、高硬度磨粒熔合组成。 硬质复合工具结构简单、制造简捷、加工成本低、耐磨 性能好、使用寿命长,便于推广应用。

Description

本实用新型硬质复合工具,特别适用于切削、磨削陶瓷、玻璃、塑料及金属材料。
目前的小型五金切削、磨削工具如手用锯条、钻头、砂轮等。对于硬度较高的非金属材料,如陶瓷、玻璃加工困难。以往对陶瓷、玻璃进行磨削、钻孔加工,采用常规五金工具无法进行,有的采用砂轮、但砂轮转速高容易破碎加工件,钻孔时一般采有软金属材料加研磨剂进行研磨钻孔速度慢效率低。
本实用新型的目的是提供一种新颖的硬质复合工具,利用金属基体上熔合的高硬度高强度复合合金层作切削磨削刃,可方便地切削磨削一般五金工具难以加工的高硬度非金属、金属材料。
硬质复合工具是采取以下方式实现的:硬质复合工具由金属基体复合合金层两部分构成。复合合金层担负切削任务具有极高硬度和强度。复合合金层由金属粉末和高硬度磨粒通过冶金方法结合而成,溶合覆在工具的金属基体切削刃部位,构成切削、磨削刃。高硬度磨粒包溶并突出于复合合金层表面,从而形成无数尖锐的切削齿。工作时正是通过这无数牢牢固定于金属基体并突出复合合金层形成无数微型切削刃的高硬度磨粒去不断地切削、磨削工件。高硬磨粒是硬质相颗粒,可采用金刚石、金属碳化物、氮化物等。金属基体采用合金钢。
硬质复合工具结构简单、制造工艺独特简捷,加工成本低,该工具耐磨性能好,使用寿命长,便于推广应用。特别适用于建筑装璜行业,对其它工具难以加工的各种陶恣,玻璃制品及墙体等进行切削、磨削及孔加工等,也可适用于其它一些材料如塑料、金属材料等。
以下将结合附图对本实用新型作进一步说明。
图1是硬质复合工具实施例1。
图2是硬质复合工具实施例2。
图3是硬质复合工具实施例3。
图4是硬质复合工具实施例3的左视图。
参照附图硬质复合工具具有金属基体(1),金属基体切削刃部位,包溶有复合合金层(2)构成硬质复合工具切削,磨削刃。复合合金层由金属粉末与高硬度磨粒溶合组成。附图1是硬质复合工具专用于切削,加工工具。附图2是硬质复合工具专用于各种孔加工工具。附图3、4是硬质复合工具专用于各种磨削加工工具。

Claims (2)

1、一种硬质复合工具,其特征是具有金属基体,金属基体切削刃部位,包溶有复合合金层,构成切削、磨削刃。
2、根据权利要求1所述的硬质复合工具,其特征是复合合金层由金属粉末、高硬度磨粒溶合组成。
