Abstract

无屑切削刀具，属于机械切削刀具领域，尤其涉及对非金属材料进行机械切削加工的刀具领域。它由刀头1和刀身2组成，刀头1安装在刀身2上，其特征在于刀头1的刀口侧夹角α＝6～12°。由于刀口侧夹角α很小，非金属材料的硬度较软，在加工非金属材料过程中刀头对被加工材料施加以挤削力将其切断，所以不产生切屑，使得其对非金属材料的利用率高达95％，而且一把刀具可连续使用1.5－2个月不需要打磨，既节省了材料又提高了工效。

Description

无屑切削刀具
技术领域
无屑切削刀具，属于机械切削刀具领域，尤其涉及对非金属材料进行机械切削加工的刀具领域。
背景技术
目前在非金属材料切削加工过程中，采用的刀具中刀头的刀口宽度较宽，其结构如图1所示。这种宽刀口的刀具用于非金属材料加工时，往往会产生大量切削，从而造成材料的浪费。特别在车削厚度较薄的片状结构零件时，材料浪费更为惊人！并且零件材料对刀具磨损也很严重。例如，当采用刀口宽度为2-3mm的硬质合金刀具切削加工厚度为1mm的聚四氟乙烯油封唇片时，其材料利用率低于30％，在一般情况下，一把刀具每4小时就需打磨一次，既浪费价格昂贵的原材料又费工费时。
发明内容
本实用新型的目的在于针对上述刀具存在的缺陷，提出一种无屑切削刀具，当用它加工非金属材料工件的过程中不会产生切屑。
本实用新型的技术解决方案如下：它由刀头1和刀身2组成，刀头1安装在刀身2上，其特征在于刀头1的刀口侧夹角α＝6～12°。一般说来，这种刀头采用硬质合金加工而成，刀身为白钢材料。由于刀口侧夹角α很小，非金属材料的硬度又较软，在加工非金属材料过程中刀头对被加工材料施加以挤削力将其切断，所以不产生切屑。
采用本实用新型技术方案制得的刀具，由于不产生切屑，使得其对非金属材料的利用率高达95％，而且一把刀具可连续使用1.5-2个月不需要打磨，既节省了材料又提高了工效。

图2(b)为本实用新型刀具俯视图。
具体实施方式
下面结合附图和实施例对本实用新型作进一步详细说明。
以加工厚度为1mm的聚四氟乙烯油封唇片刀具为例，其刀头1的刀口夹角α＝9°，硬质合金刀头1长20mm，高8mm，白钢刀身2长150mm，高20mm，厚5mm。
