Description
技术领域：Technical field:
本发明涉及一种模具用可转位球头铣刀。The invention relates to an indexable ball end milling cutter for a mold.
背景技术：Background technique:
汽车大型覆盖件模具有结构尺寸大、形状复杂、尺寸精度和表面精度要求高的特点。其模具材料多为Cr12MoV 和7CrSiMnMoV 等模具钢，淬火后硬度达到HRC50-65，属于典型高强度、高硬度材料，这种高硬度材料在加工过程中，刀具的磨损与破损情况非常严重，目前工厂中所使用的镜面球头铣刀为非转位的，一个刀片失效后，一部分需要重磨后使用，一部分完全失效，不能继续使用，降低了生产效率，增加了刀具的使用成本。并且由于以往球头铣刀顶点处线速度为零，在加工中刀尖处易产生磨损，甚至产生崩刃。尤其在加工汽车模具中平面位置时，这种由于刀尖线速度为零而导致的加工表面质量变差、刀具寿命降低的情况尤为严重。Large-scale automotive panel molds have the characteristics of large structural size, complex shape, and high requirements for dimensional accuracy and surface accuracy. Most of the mold materials are die steels such as Cr12MoV and 7CrSiMnMoV. After quenching, the hardness reaches HRC50-65, which is a typical high-strength and high-hardness material. During the processing of this high-hardness material, the tool wear and damage are very serious. The mirror ball-end milling cutter used in the machine is non-reversible. After one blade fails, part of it needs to be regrinded before use, and part of it fails completely and cannot be used any longer. This reduces production efficiency and increases the cost of using the tool. And because the linear velocity at the apex of the ball end milling cutter in the past is zero, the tip of the cutter is prone to wear and even chipping during processing. Especially when machining the mid-plane position of automobile molds, the deterioration of the machined surface quality and the reduction of tool life due to the zero linear velocity of the tool tip are particularly serious.
