Description
高精度涂层焊硬质合金螺旋波形立铣刀
技术领域：
[0001] 本实用新型涉及一种高精度涂层焊硬质合金螺旋波形立铣刀，本实用新型属于铣刀技术领域。
背景技术：
[0002]目前国内外生产和使用的螺旋立铣刀，在切削时，因切削强度不均衡，刀体震动剧烈，容易损坏硬质合金刀刃，降低使用寿命，为了避免刀具损坏，必然要减少切削量，从而效率降低。而且现在的螺旋铣刀，都采用钢质材料制成，铣削过程中容易磨损，或者对孔壁产生破坏，光洁度低，容易留下铣削痕迹。
实用新型内容：
[0003] 本实用新型的目的是针对现有技术的上述缺点，提供一种高精度涂层焊硬质合金螺旋波形立铣刀。从而避免切削强度的不均，减小切削时的振动，提高切削效率和刀具寿命O
[0004] 本实用新型的技术方案：
[0005] 高精度涂层焊硬质合金螺旋波形立铣刀，其包括有刀体柄部和带有螺旋槽的螺旋刀头，螺旋刀头上有刀体螺旋排屑槽和刀体刃部，刀体刃部上有合金刀齿，合金刀齿为波纹形状，刀体刃部与合金刀齿采用焊铜焊接。刀头上设置有四刃刀削头，螺旋刀头的螺旋角为25度〜30度，四刃切削头的切削后前角度为8度〜10度。
[0006] I、所述的高精度涂层焊硬质合金螺旋波形立铣刀，其特征在于：所述的合金刀齿工作部分的圆柱度0.01mm。
[0007] 2、所述的高精度涂层焊硬质合金螺旋波形立铣刀，刀体柄部和带有螺旋槽的螺旋刀头，都由硬质合金制成，刀体刃部与合金刀齿采用焊铜焊接。
[0008] 本实用新型的优点是：采用硬质合金材料制成的立铣刀了切削速度，而强度高，耐磨性好，使用寿命长。
附图说明：
[0009] 图I :本实用新型结构示意图。
[0010] 图2 :本实用新型结构螺旋刀头的截面图
具体实施方式：
[0011] 本实用新型结构包括：刀体柄部1，螺旋刀头2，刀体刃部3，刀体螺旋排屑槽4，焊铜5,合金刀齿6。
[0012] 以下结合附图说明本实用新型的具体实施方式：高精度涂层焊硬质合金螺旋波形立铣刀，共包括有刀体柄部I和带有螺旋槽的螺旋刀头2，本实用新型螺旋刀头2采用四刃切削头，刀体刃部3上设置有合金刀齿6，合金刀齿6为波纹形状，刀体刃部3的螺旋角为25度〜30度，让切削面更大，更好的进行铣削工作，合金刀齿6的切削角为10度〜20度，切削前角设置为8〜10度，让铣削过程中更加快捷，铣削孔壁光洁，不易产生线痕，更好的运用于高硬度及难加工材料的产品加工，适合台阶面加工，孔加工。刀体刃部3上通过焊铜5焊接合金刀齿6，合金刀齿6工作部分的圆柱度为O. 01mm。刀体柄部I和刀体刃部3都采用合金结构钢制成，合金刀齿6由硬质合金制成,强度高,耐磨性好,使用寿命长。
[0013] 根据上述说明书的揭示和教导，本实用新型所属领域的技术人员还可以对上述实施方式进行变更和修改。因此，本实用新型并不局限于上面 揭示和描述的具体实施方式，对本实用新型的一些修改和变更也应当落入本实用新型的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本实用新型构成任何限制。
