Abstract

本实用新型提供了一种改进的滚花刀,其特征是 在滚花刀上设置了引导角,引导角可在10-45°间选 值,尤以15-30°为佳。加工时轴向力、径向力大大 减少,耐用度高,使用寿命长。被加工件光洁度高,不 烂齿。

Description

本实用新型涉及的是一种改进的滚花刀。
公知的单轮或双轮滚花刀用于工件加工中,因属单向滚压,工件侧面受力,故当工件刚度小(如细长轴、薄壁件)时易产生变形;因属自由滚压,易烂花、影响工件光洁度而导至光洁度差。
鉴于以上原因,本实用新型的目的是为了提供一种能提高被加工工件光洁度、不烂花的滚花刀。
本实用新型是在公知的滚花刀上的改进,其特征是在滚花刀上设有引导角α(参见图1),这样可使本实用新型滚花刀在滚压过程中其上的齿与被加工工件上已形成齿的部份有一个短暂的相对运动,不但解决了在不同速度下在滚压变形中滚压齿的节圆直径不断变化很易烂齿的问题而且同时也克服了滚压齿与被加工工件已形成齿不重合而影响光洁度的问题。
上述的引导角α可选用10-45°中的任一值。
上述的引导角α可为15-30°,滚压时所产生的轴向力和径向力最小。
本实用新型滚花刀上设置了引导角,解决了被加工件易烂齿的问题,且提高了被加工件的光洁度。由于设置了引导角,加工时减小了轴向刀和径向力。经测试,轴向力为公知的滚花刀加工时产生轴向力的1/5,径向力为公知的滚花刀加工时产生径向力的1/10,增加了刀子的耐用度,使用寿命长,为原公知的滚花刀的10倍以上。
下面结合附图详细说明本实用新型的实施例:
图1:本实用新型结构示意图
图2:图1的俯视图
图1、图2给出了本实用新型的实施例图,在本实用新型的两端上设置了引导角α。引导角α可在10-45°之间取值,尤以15-30°为最佳。

Claims (3)

1、滚花刀,其特征在于所述的滚花刀上有引导角α。
2、如权利要求1所述的滚花刀,其特征在于所述的引导角α可取10-45°值。
3、如权利要求2所述的滚花刀,其特征在于所述的引导角α为15-30°。
