Description

微切丝锥 技术领域
本发明涉及一种微切丝锥，具体地说涉及一种微切丝锥，本技术方案用于机械加工中对工件的丝孔加工，新的机械加工理论认为分段即阶梯状切削刃切削效率高，然而当阶梯状切削刃逐渐延长后就会发现其效果明显下降直至消失，因此该理论仍然不是真正正确的理论。
背景技术：
目前，机械加工中使用的螺旋微切丝锥或复合切削丝锥或直槽微切丝锥或复合切削丝锥是由丝刃体和丝柄构成，丝刃体又由丝刃条和切削刃面，丝刃、倒角、倒角刃等构成，丝刃，倒角刃的切削刃面大致在一个曲面或同一个螺旋面上，每个丝刃条的丝底连线大致在一条直线或螺旋上，由于倒角处丝顶到丝底距离过小起不到导向作用，结果攻丝成了扩孔，造成工件报废，并且，由于每一组的丝刃面是由单一面组成，当切削刃面与丝顶夹角过于锐利时则丝刃易断裂，如切削刃面与丝顶之间夹角过大时出现丝柄与夹装工具间扭力过大易造成微切丝锥或复合切削丝锥整体断裂在工件中致使工件质量受损甚至报废人们普遍的认识是表面越光滑强度越高，新的理论则是有微小间隙的面强度更高，都没有揭露物质的本质结构特性，因此，现有孔加工刀具效率低，易损坏，稳定性差，钻孔精度差。
发明内容：
本发明就是鉴于上述的问题而提出的，以提供一种分径移位麻花钻为目的，该种刀具具有阻断传导力的功能，散热效率高，强度大，寿命长，且在钻削加工时容易定位，钻孔精度高，人们普遍的认识是表面越光滑强度越高，最近几年的新的理论则是有微小间隙的面强度更高，都没有揭露物质的本质结构特性，在两个固体体积相同的情况下，其中分散成的小体积的固体的表面积大于整体的固体的表面积，固体的整体结构达到一定体积极限时即使是金刚石也会碎裂，按体积受力的情况下小体积的固体受力强度之和远大于整体的固体的受力强度，经过实验验证在常规物理状态下的切削工具上，毫米量级有最明显的高强度特性即毫米强度，本发明是在分径移位麻花钻进行具有毫米强度的应用。
本发明就是鉴于上述的问题而提出的，以提供一种微切丝锥，该种微切丝锥容易定位，散热效率高，耐磨损，寿命长。

实施方式2
如图4-5所示，第二实施方式的微切丝锥，包括丝刃体1和丝柄2，在第一实施方式的基础上本发明应用于螺旋丝锥，该丝刃体2和丝柄1联接或形成为一体，丝刃体2上一体的设置多个丝刃条，在丝刃体上形成有切削刃面9，丝刃体2的前端倒角形成有倒角丝顶面4，在切削刃面9的边缘或从内侧向外侧凹陷的设置具有毫米强度的微强化应力延展台10，具有毫米强度的微强化应力延展台10与前端面相交形成有侧微刃7，切削刃面9的外侧切削刃面形成为具有毫米强度的螺旋微切刃面6，具有毫米强度的螺旋微切刃面6与后丝刃面116相交的丝刃形成为具有毫米强度的微切刃7，具有毫米强度的螺旋微切刃面6与丝刃体的倒角面4相交形成有倒角刃8，凸起的具有毫米强度的微强化应力延展台10对具有毫米强度的螺旋微切刃面6形成应力延伸，强化了具有毫米强度的螺旋微切刃面6的强度和散热效果大大提高了切削刃面7和丝刃的抗裂强度，大幅度提高了切削效率，并延长了微切丝锥的使用寿命。
所述的微切丝锥的切削刃面9上从外边缘顶端向轴向中心的切削刃面9上凹陷的设置具有毫米强度的微切刃面6；所述的具有毫米强度的微切刃面6的宽度 为大于等于0.6mm，小于等于10mm。
所述的微切丝锥的切削刃面9上从外边缘顶端向轴向中心的切削刃面上凹陷设置的具有毫米强度的微切刃面6的内侧立起的设置具有毫米强度的微强化应力延展台10，立起的具有毫米强度的微强化应力延展台10与内侧凸起的切削刃9面相交形成有具有毫米强度的复合丝刃；
所述的具有毫米强度的微强化应力延展台10的高度为大于等于0.15mm，小于等于6mm。
所述的微切丝锥具有毫米强度的微强化应力延展台10与丝刃体的后丝刃面11相交形成有侧微刃7；所述的微切丝锥的具有毫米强度的侧微刃7的长度为大于等于0.15mm，小于等于6mm；
所述的微切丝锥的具有毫米强度的微切刃面6与丝刃体的后丝刃面11相交形成有具有毫米强度的切削微刃5；所述的微切丝锥的具有毫米强度的切削微刃5的长度为大于等于0.6mm，小于等于10mm。
由于设置了具有毫米强度的微强化应力延展台10增强了具有毫米强度的微切刃面17或具有毫米强度的螺旋微切刃面6的强度，而具有毫米强度的微切刃面6或具有毫米强度的螺旋微切刃面6本身由于面积变小复合小而强的特点，特点是相同的材质按其体积计算其一侧表面积毫米级的平均强度大于厘米级，而厘米级大于分米级，1立方厘米＝1千个立方毫米，而面积则是1立方厘米的表面积＝6百平方毫米的表面积，1千个立方毫米的表面积是6千平方毫米，按体积平均施加的力在1立方厘米是1千个立方毫米的表面积计算的十倍，因此毫米级承受压强极限远大于厘米级，再加上具有毫米强度的微强化应力延展台10所延伸的力，具有支撑和加强具有毫米强度的微切刃面6强度的效果，因而是在同一刀具上的设置具有很高的强度和稳定性，相比普通制齿刀具具有更加耐用和强度刃度稳定性的优势，因此具备高效率的优势，使用寿命更长。
根据上述结构，由于丝刃切削是圆周运动，在圆周运动的过程中产生了离心力，切削刃形成了离心力的传导载体，切削面与相邻的具有毫米强度的微强化应力延展台10和具有毫米强度的微切刃面6或具有毫米强度的螺旋微切刃面6与后丝刃面11相交形成的具有毫米强度的微切刃5在切削刃面9上增加了阶梯面即微强化应力延展台10，将传导力进行了分化，减小了整体切削力，最大限度的减小了切削刃面7的外侧具有毫米强度的微切刃面6或具有毫米强度的螺旋微切刃面6与后丝刃面11相交形成的微切刃5的受力作用，降低刀具头温度，分解刀具最易损坏的外端的具有毫米强度的微切刃5的受力，使刀具使用寿命延长，并在加工过程中一直保持高强度。
以上所述的优选实施方式是说明性的而不是限制性的，在不脱离本发明的主旨和基本特征的情况下，本发明还可以以其他方式进行实施和具体化，本发明的范围由权利要求进行限定，在权利要求限定范围内的所有变形都落入本发明的范围内。
