技术领域technical field
本实用新型涉及的车刀领域，具体涉及一种劈面车外圆复合车刀。The utility model relates to the field of turning tools, in particular to a compound turning tool for face-to-face turning and outer circle.
背景技术Background technique
现有技术方案采用DCLNL刀先车端面，再车外圆。这种加工方式具有以下缺陷：由于产品为钢件，立式锻造成形，端面有残留飞边，长短大小不一，形状不规则。车端面时余量不均，工况很差；车端面时用CNMG刀片80°锐角，刀尖强度较差，容易崩刃；95°主偏角，车端面反作用力的径向分力很大，轴向分力与工件夹持方向相反，影响夹持刚性，进而影响刀具寿命。The prior art scheme uses a DCLNL cutter to turn the end face first, and then turn the outer circle. This processing method has the following defects: because the product is a steel part, which is formed by vertical forging, there are residual flashes on the end surface, which are of different lengths and sizes, and have irregular shapes. When turning the end face, the margin is uneven, and the working condition is very poor; when turning the end face, use CNMG blade with 80° acute angle, the strength of the blade tip is poor, and it is easy to chip; 95° entering angle, the radial component of the reaction force on the end face is very large , the axial component force is opposite to the clamping direction of the workpiece, which affects the clamping rigidity and thus affects the tool life.
实用新型内容Utility model content
本实用新型的目的在于克服现有技术存在的不足，而提供一种劈面车外圆复合车刀。The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a compound turning tool for splitting and excircle.
本实用新型的目的是通过如下技术方案来完成的：这种劈面车外圆复合车刀，主要包括复合刀排、刀片A、刀片B，复合刀排前端安装刀片A和刀片B，且刀片B安装在刀片A前端。所述刀片A成75°主偏角车端面,所述刀片B成95°主偏角车外圆,所述刀片A刀尖角度为100°钝角,所述刀片B刀尖角度为80°锐角,所述刀片A和刀片B均采用CNMG刀片。The purpose of this utility model is to be accomplished through the following technical proposals: this kind of face-to-face turning outer circle composite turning tool mainly includes composite blade row, blade A, blade B, blade A and blade B are installed at the front end of composite blade row, and blade B Installed on the front of blade A. The end face of the blade A is turned at a leading angle of 75°, the outer circle of the blade B is turned at a leading angle of 95°, the angle of the blade A of the blade A is an obtuse angle of 100°, and the angle of the blade B of the blade B is an acute angle of 80° , the blade A and the blade B both adopt CNMG blades.
本实用新型的有益效果为：本实用新型为复合车刀，根据工装、工件的结构和尺寸设计，能有效改善刀片崩刃情况，提高刀具寿命；改善切削力分布，提高夹持刚性。The beneficial effects of the utility model are: the utility model is a composite turning tool, designed according to the structure and size of the tooling and the workpiece, which can effectively improve the chipping of the blade, improve the tool life, improve the cutting force distribution, and increase the clamping rigidity.

具体实施方式Detailed ways
下面将结合附图对本实用新型做详细的介绍：The utility model will be described in detail below in conjunction with the accompanying drawings:
实施例：如附图所示，这种劈面车外圆复合车刀，主要包括复合刀排3、刀片A4、刀片B5，复合刀排3前端安装刀片A4和刀片B5，且刀片B5安装在刀片A4前端。刀片A4成75°主偏角车端面。切削力的径向分力相对较小，轴向分力与夹持力方向一致，有助于提高夹持系统刚性。刀片A4刀尖角度为100°钝角。100°钝角刀尖强度更好，刀片利用率提高1倍，寿命提高50％。车端面进给速度提高50％。刀片B5成95°主偏角车外圆。刀片B5刀尖角度为80°锐角。刀片A4和刀片B5均采用CNMG刀片。本实施例中为CNMG1204刀片。Embodiment: As shown in the accompanying drawings, this compound turning tool for splitting the outer circle mainly includes a compound knife bank 3, a blade A4, and a blade B5. The front end of the compound knife bank 3 is equipped with a blade A4 and a blade B5, and the blade B5 is installed on the A4 front. Insert A4 turns the end face at a 75° entering angle. The radial component of the cutting force is relatively small, and the axial component is in the same direction as the clamping force, which helps to improve the rigidity of the clamping system. The blade A4 has an obtuse angle of 100°. The 100°obtuse angle tip has better strength, the utilization rate of the blade is doubled, and the service life is increased by 50%. Turning face feed speed increased by 50%. Insert B5 turns the outer circle at a 95° entering angle. Blade B5 has an acute angle of 80°. Both blade A4 and blade B5 use CNMG blades. In this embodiment, it is CNMG1204 blade.
