Description

三方钻头
本实用新型涉及一种用于机械加工方面的三方钻头。
目前我们使用的钻头通常为麻花钻,麻花钻在遇到坚硬的物质时不易钻进,很容易被折断。
本实用新型的目的就是提供一种遇到坚硬物质时容易钻进,且不易折断的三方钻头。
本实用新型的技术方案是通过以下途径实现的,它的工作部分由三方合金压制而成的三棱柱形。
本实用新型具有简单多刃,耐磨,功效高,成本低。可应用于机械加工、修理、合金模具钢淬火前后的加工,且在很多模具制造过程中起关键作用。
图1为本实用新型的结构示意图。
图2为本实用新型的工作部分结构示意图。
下面结合附图详细描述本实用新型的技术方案和实施例。
本实用新型含工作部分1、柄部2,所述的工作部分1是由三方合金压制而成的三棱柱形,柄部2呈圆柱形,采用优质钢材制成,工作部分1和柄部2之间采用组合式焊接而成。

Claims (1)

1、一种三方钻头,含工作部分(1)、柄部(2),其特征在于所述的工作部分(1)是由三方合金压制而成的三棱柱形。
