Abstract

本实用新型涉及一种钻头。其为铜制品加工中钻孔而设计的。该钻头其特征在于圆柱形钻体前端部分为呈缺口圆弧形切削体,切削体尖端为引孔部位。它具有结构简单、制造容易、适宜铜制品钻孔使用。

Description

特种高速扁钻
本实用新型涉及一种高速自动仪表车的专用工具钻头技术领域。
生产各类铜制品常常需要打眼钻孔加工,在工作过程中需用耐磨性能强、切削量大的钻头。但是常用一般钻头来切削铜材料不是很理想。如专利号为93114822.7的中国专利单管内排屑深孔喷吸钻,具有刀刃强度大,但是钻头烧结制作有一定难度,而且用于切削铜材料,由于出屑来不及会影响钻头打孔效率。
因此本实用新型目的在于提供一种结构简单、适宜铜制品钻孔的钻头特种高速扁钻。
本实用新型的技术方案是这样实现的。该钻头在圆柱形钻体前端部分为呈缺口圆弧形切削体,切削体尖端为引孔部位。
并且上述切削体根部缺口端面呈倒角斜面,切削体在缺口两边切削部位磨成刃状。
该钻头有缺口圆弧形切削体具有钻孔切削量大,而且缺口为排屑提供了出屑通道,排屑量大,提高了钻孔效率,并且该钻头有结构简单、加工容易、制造成本低等优点。
附图说明:
图1.特种高速扁钻结构示意图。
下面结合附图对本实用新型的实施例作进一步说明。
如图所示,该钻头钻体分成两段形状,在圆柱形钻体(1)前端部分为呈缺口圆弧形切削体(3),切削体尖端为引孔部位(4),并且切削体根部缺口端面呈倒角斜面,切削体缺口两边切削部位(2)磨成刃状。

Claims (3)

1.一种钻头,其特征在于圆柱形钻体(1)前端部分为呈缺口圆弧形切削体(3),切削体尖端为引孔部位(4)。
2.如权利要求1所述的钻头,其特征在于所述切削体根部缺口端面呈倒角斜面。
3.如权利要求1所述的钻头,其特征在于所述切削体在缺口两边切削部位(2)磨成刃状。
