Abstract

磨摆铣刀，是以对船用螺旋桨粗加工用铣刀结构的改进。磨摆铣刀，包括刀体和硬质合金刀片，硬质合金刀片焊接在刀体上，其特征在于硬质合金刀片的尖角制成2×45°倒角，硬质合金刀片切削刃后角制成9°，硬质合金刀片切削刃前角制成0°。优点：因为将刀片刀尖制成2×45°倒角，提高了刀尖处的强度，避免了刀尖极易崩齿现象；将前角制成0°，后角制成9°，增加了刀具的强度，刀具不易损坏，降低了生产成本。

Description

磨摆铣刀 
技术领域：本发明创造是以对船用螺旋桨粗加工用铣刀结构的改进。 
背景技术：船用螺旋桨毛坯料的加工余量非常大，在粗加工时，每次的切刀深度均在4mm以上，对磨摆铣刀的磨摆铣刀磨损严重，原有船用螺旋桨粗加工用铣刀的刀尖均为尖角，切削刃前角大，数值为5°，后角大，数值为12°，在每次加工过程中，刀片破碎现象非常普遍，尤其刀尖部分的崩齿更为严重，造成刀具无法返修利用，提高了生产成本。 
发明内容：本发明创造的目的是提供一种能增加刀具寿命，降低生产成本的磨摆铣刀；本发明创造的目的是通过下述的技术方案实现的：磨摆铣刀，包括刀体和硬质合金刀片，硬质合金刀片焊接在刀体上，其特征在于硬质合金刀片的尖角制成2×45°倒角，硬质合金刀片切削刃后角制成9°，硬质合金刀片切削刃前角制成0°。 
本发明创造的优点：因为将刀片刀尖制成2×45°倒角，提高了刀尖处的强度，避免了刀尖极易崩齿现象；将前角制成0°，后角制成9°，增加了刀具的强度，刀具不易损坏，降低了生产成本。 
附图说明：
图1是磨摆铣刀结构示意图； 
图2是图1中的A向局部放大示意图； 
图3是图2中沿B-B线剖面视图。 
图中的：1、刀体2、硬质合金刀片3、片的尖角制2×45°倒角4、硬质合金刀片切削刃后角5、硬质合金刀片切削刃前角 
具体实施方式：磨摆铣刀，包括刀体和硬质合金刀片，硬质合金刀片焊接在刀体上，其特征在于硬质合金刀片的两个尖角制成2×45°倒角，硬质合金刀片切削刃后角制成9°，硬质合金刀片切削刃前角制成0°。 
采用该结构的磨摆铣刀，刀具的使用寿命提高了，用该刀具加工的产品是用原刀具加工的产品数量的2至3倍，因而降低了生产成本。
