Description
—种二刃铝用圆鼻铣刀
技术领域:
[0001 ] 本实用新型涉及二刃铣刀的技术领域，更具体地说涉及二刃铝用圆鼻铣刀。
背景技术:
[0002] 铣刀是现代工业机加工中所使用的一种重要刀具，现在的铣刀可以根据刀刃分为单头铣刀、二刃铣刀及其常见的三刃铣刀等。而二刃铣刀专用的键槽铣刀，现在一些加工一些滑槽时，会在滑槽两侧面的下端加工成型有间隙槽增加空气流动，能够防止滑槽内的滑块吸在滑槽内不动，同时间隙槽又可以作为灰尘、磨屑的排出槽。但在加工这些间隙槽往往需先加工出滑槽，间隙槽在二次加工中成型，从而增加了加工的工作时间，增加了生产成本。
实用新型内容:
[0003] 本实用新型的目的就是针对现有技术之不足，而提供二刃铝用圆鼻铣刀，其能使滑槽和间隙槽同时加工，减少加工的工作时间，减少了生产成本。
[0004] 为实现上述目的，本实用新型的一种二刃铝用圆鼻铣刀包括刀柄和刀头，其中，刀头上成型有两组相对称的螺旋状切屑刃，两切屑刃之间成型有切屑槽，所述的刀头的前端为两相对刀头中心轴线对称的切屑刃前端面，切屑刃前端面与刀头的中心轴线相垂直，切屑刃前端面与切屑刃连接部位成型有圆角，所述的圆角的圆弧大于整圆中1/4的圆弧。
[0005] 作为上述技术方案的优选，所述的切屑槽后端成型有V型的槽尾，槽尾端的切屑刃与与水平线的夹角β为45°。
[0006] 作为上述技术方案的优选，所述的为小型铣刀，所述刀头的直径位于I〜3mm之间，圆角的尺寸偏差为±0.01mm。
[0007] 本实用新型的有益效果在于:其在铣刀的刀尖处成有一个鼻形的圆角，可以在铣刀进行铣削的同时对所需加工的间隙槽同时加工，从而减少了大半的加工生产的时间，同时减少了设备运行的费用，从而降低了生产成本，促进了生产效率。
附图说明:
[0008] 下面结合附图对本实用新型做进一步的说明:
[0009] 图1为本实用新型的结构示意图；
[0010] 图2为本实用新型的图1中A处的放大示意图；
[0011] 图3为本实用新型的刀头2的右视放大图。
[0012] 图中符号说明:
[0013] 1、刀柄；2、刀头；3、切屑刃；4、切屑槽；5、切屑刃前端面；6、槽尾；7圆角。
具体实施方式:
[0014] 见图1至图3所示:本实用新型的二刃铝用圆鼻铣刀包括刀柄I和刀头2，刀头2上成型有两组相对称的螺旋状切屑刃3，两切屑刃3之间成型有切屑槽4，所述的刀头2的前端为两相对刀头2中心轴线对称的切屑刃前端面5，切屑刃前端面5与刀头2的中心轴线相垂直，切屑刃前端面5与切屑刃3连接部位成型有圆角7，所述的圆角7的圆弧大于整圆中1/4的圆弧。
[0015] 切屑槽4后端成型有V型的槽尾6，槽尾6端的切屑刃3与与水平线的夹角β为45。。
[0016] 为小型铣刀，所述刀头的直径位于I〜3mm之间，圆角7的尺寸偏差为±0.01mm。
[0017] 工作原理:本实用新型在二刃铣刀的一个鼻形的圆角，使其相当与代替了铣削滑槽的铣刀和铣削间隙槽的铣刀，使铣削滑槽和铣削间隙槽同时进行，相当减少了二次铣削间隙槽的过程，从而缩短了加工生产的时间，同时减少了设备运行的费用，从而降低了生产成本，促进了生产效率。
[0018] 以上内容仅为本实用新型的较佳实施例，对于本领域的普通技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，本说明书内容不应理解为对本实用新型的限制。
