采用上述静刀结构及其加工工艺，其优点在于：The advantages of adopting the above static knife structure and its processing technology are:
1、由金属片材一体加工成型，加工方便，制造成本低；1. It is integrally processed and formed from sheet metal, which is easy to process and low in manufacturing cost;
2、先在金属片材上加工进须槽孔，然后进行弯折成型，更方便进须槽孔的加工处理，保证得到无毛刺、无飞边的效果；2. First process the whisker slot holes on the metal sheet, and then perform bending forming, which is more convenient for the processing of the whisker slot holes and ensures the effect of no burrs and flashes;
3、平面接触部平整光滑，能够更好地与皮肤接触移动，保证剃须的舒适度以及剃须效果；3. The plane contact part is flat and smooth, which can better contact and move with the skin, ensuring the comfort and effect of shaving;
4、所述连接部2与平面接触部1、限位部3之间圆弧过渡，其圆弧半径R为0.1-0.3mm，其圆弧结构，能够进一步减少棱角，保证剃须时的舒适度。4. The arc transition between the connecting part 2 and the plane contact part 1, the limit part 3, the arc radius R is 0.1-0.3mm, and the arc structure can further reduce the edges and corners and ensure the comfort during shaving degree.
所述进须槽孔6则是通过蚀刻工艺或电解加工工艺制得，确保进须槽孔6无毛刺，无飞边。The whisker inlet slot 6 is made by an etching process or an electrochemical machining process to ensure that the whisker inlet slot 6 is free of burrs and flashes.
如图所示，所述安装部4包括倾斜段41与竖直段42，所述倾斜段41与限位部3连接并保持一定倾斜角度θ，该倾斜角度θ为26-32°，所述竖直段42与倾斜段41连接并保持竖直，所述竖直段42上形成有若干安装孔43。As shown in the figure, the mounting portion 4 includes an inclined section 41 and a vertical section 42. The inclined section 41 is connected to the limiting section 3 and maintains a certain inclination angle θ. The inclination angle θ is 26-32°. The vertical section 42 is connected to the inclined section 41 and kept vertical, and a plurality of mounting holes 43 are formed on the vertical section 42.
通过竖直段42的安装孔43与静刀座配合安装，安装方便，安装时，需要通过向两侧掰开，使得安装部4轻微变形以方便套在静刀座上，而将安装部4分成倾斜段41与竖直段42，能够有效减少因向两侧掰开而产生的变形，同时避免折断。The installation hole 43 of the vertical section 42 is matched with the static knife holder, which is convenient for installation. During installation, the installation part 4 needs to be slightly deformed by breaking it to both sides to facilitate the fitting on the static knife holder, and the installation part 4 Divided into an inclined section 41 and a vertical section 42 can effectively reduce the deformation caused by breaking to both sides and avoid breaking.
经过实验发现，倾斜段41的倾斜角度太大，剃须效果不好，影响剃须体验，若倾斜段41的倾斜角度太小，又容易折断，当处于26-32°范围内的角度时最好，既不容易折断，又保证剃须效果。After experiments, it is found that the inclination angle of the inclined section 41 is too large, and the shaving effect is not good, which affects the shaving experience. If the inclination angle of the inclined section 41 is too small, it is easy to break. When the angle is within the range of 26-32° Good, it is not easy to break, but also guarantees the shaving effect.
所述安装孔43可以在加工进须槽孔之前，提前在金属片材宽度方向的左右两侧 位置加工而出，降低加工难度，提高加工精度。The mounting holes 43 can be processed in advance at the left and right sides in the width direction of the metal sheet before processing the whisker slot holes, which reduces processing difficulty and improves processing accuracy.
