Abstract

本实用新型公开了一种钻断丝锥用的硬质合金 钻头,它是在方形整体高强度硬质合金钻头的刃部焊 上一高硬度硬质合金薄片,并在其尾部焊接一钢体夹 柄构成。它既能满足钻断丝锥的硬度要求,又不易折 断,而且尾部设有钢体夹柄,使用时便于装夹。

Description

本实用新型涉及一种钻断丝锥用的硬质合金钻头。
由于钻断丝锥的硬度高达HRc60以上,所以要求钻断丝锥钻头的硬质合金具有很高的硬度及特殊形状。现国外有一种方形整体硬质合金钻头可作钻断丝锥之用,但它由于考虑到硬质合金的高硬度而其强度受到一定限制,在使用时易于折断。
本实用新型的目的是提供一种既能满足钻断丝锥的硬度要求,又不易折断的硬质合金钻头。
本实用新型的目的是这样实现的:它是在方形整体高强度硬质合金钻头的刃部焊上一高硬度硬质合金薄片,并在其尾部焊接一钢体夹柄构成。
图1,为方形整体硬质合金钻头结构示意图。
图2,为本实用新型结构示意图。
从图中可以看出,本实用新型是在高强度硬质合金钻头2的刃部焊上一高硬度硬质合金薄片1,这样既满足了钻断丝锥的硬度要求,又不易折断,另一方面在尾部焊上一钢体夹柄3,使用时便于装夹。
