Description
技术领域technical field
本发明涉及手机铝边框倒角刀具技术领域,特别涉及一种手机铝边框单晶钻石PCD双刃组合倒角刀。The invention relates to the technical field of chamfering cutters for aluminum frames of mobile phones, in particular to a single crystal diamond PCD double-edged combined chamfering cutter for aluminum frames of mobile phones.
背景技术Background technique
机械加工中,刀具是机床加工不可缺少的主要部件, 刀具质量的好坏影响到自身的使用寿命,也影响到机械加工的质量以及生产效率。如手机部件高光部位,其都是高精度的倒角,中国专利授权公告日为2016.11.16,授权公告号为CN205684735U,申请号201620657902 .7,专利名称为一种单晶钻石PCD双刃组合倒角刀,倒角头上设有倒角切割面,所述的倒角头位于刀柄中心轴的外侧且位于刀柄的外边缘,所述刀柄的底部与倒角头之间为一平直的刀柄斜面,所述的倒角切割面为矩形;倒角切割面的始端与刀柄斜面之间由竖直设置的倒角头内侧面相连接,倒角切割面的右侧边缘与倒角头的外侧面之间由一平直的倒角头斜面相连接。本新型的倒角切割面在使用的时候绕刀体的中心轴旋转,在手机的上表面四个边角进行加工时,倒角刀转动可直接同时对手机上表面的一边角进行倒角,节约了一半的重复加工时间,同时,倒角刀的头部与柄部削掉了一部分,减少了刀体的重量,使驱动时的干涉更加少。上述刀具是一体式加工而成的,进行高精度倒角时是需要两把刀进行倒角,分为粗倒角刀和精倒角刀,一般先是通过粗倒角刀先进行倒角,然后再更换一把精倒角刀进行倒角,这样导致加工效率低,刀具成本高。In mechanical processing, the tool is an indispensable main part of machine tool processing. The quality of the tool affects its service life, and also affects the quality of mechanical processing and production efficiency. For example, the high-gloss parts of mobile phone parts are all high-precision chamfers. The Chinese patent authorization announcement date is 2016.11.16, the authorization announcement number is CN205684735U, and the application number is 201620657902.7. The patent name is a single crystal diamond PCD double-edged combination chamfer For a corner knife, the chamfering head is provided with a chamfering cutting surface, and the chamfering head is located outside the central axis of the knife handle and the outer edge of the knife handle, and there is a flat surface between the bottom of the knife handle and the chamfering head. Straight handle slope, the chamfered cutting surface is rectangular; the chamfered cutting surface is connected by a vertically arranged chamfering head inner side between the beginning of the chamfered cutting surface and the chamfered cutting surface, and the chamfered cutting surface is connected to the The outer surfaces of the corner heads are connected by a straight chamfering head slope. The chamfering cutting surface of this new type rotates around the central axis of the cutter body when in use. When processing the four corners of the upper surface of the mobile phone, the chamfering knife can directly chamfer one corner of the upper surface of the mobile phone at the same time. Half of the repeated processing time is saved. At the same time, part of the head and shank of the chamfering knife is cut off, which reduces the weight of the knife body and reduces the interference during driving. The above tools are processed in one piece. When performing high-precision chamfering, two knives are needed for chamfering. They are divided into rough chamfering knives and fine chamfering knives. Then replace a fine chamfering knife for chamfering, resulting in low processing efficiency and high tool cost.
