Abstract

本发明所述的硬质合金螺丝刀头是一种使用寿命长、经久耐用的螺丝刀头。本产品采用硬质合金制成，抗弯强度高，尤其是YG系列硬质合金。生产本产品时可根据需要采用粉末冶金的方法制造各种形状的螺丝刀头，如十字形、一字形、方形、星形等，螺丝刀头加工成型后与螺丝刀杆体固连成一体。由于硬质合金具有高硬度、高强度及耐磨的特点，因此大大地增加了螺丝刀头的使用寿命。另外，本产品所用材料较少故不会对螺丝刀的整体成本产生重大影响。

Description

硬质合金螺丝刀头
本发明所述的硬质合金螺丝刀头是一种用于螺丝刀上的采用硬质合金制成的螺丝刀头。
目前，市场销售的螺丝刀多为刀头与刀杆一体结构且采用普通金属制成，这种螺丝刀刀头硬度低、耐磨性差，经常出现刀头损坏而螺丝刀杆却完好无损的情况，因而使得螺丝刀头的使用寿命与螺丝刀杆使用寿命不相一致，造成了一定的材料浪费，有时还由于螺丝刀头品质差而使螺钉头部受损，
鉴于上述现有技术所存在的问题本发明的目的是设计一种与螺丝刀杆使用寿命相匹配且坚固耐用的硬质合金螺丝刀头。
本发明所述的硬质合金螺丝刀头，其结构在于螺丝刀头为单体，可与螺丝刀杆体嵌插后固装成一体，螺丝刀头采用硬质合金材料制成；本发明所述的螺丝刀头可采用焊接、螺纹或插槽方式与螺丝刀杆体连接；本发明所述的螺丝刀头可以制成十字形、一字形、方形、六方形、星形等形状；本发明所述的螺丝刀头的材质可选YG系列中的YG20或YG20C材料。
本发明所述的硬质合金螺丝刀头由于其采用硬质合金材料制成，而硬质合金材料具有高硬度、高强度及耐磨性好等特点，因此采用该材料制成的螺线刀头的使用寿命大大增加，同时也能满足强度的要求。另外，本产品所用材料较少故不会很大程度地增加螺丝刀的成本。本发明从根本上解决了原有技术所存在的刀头易损坏，刀头与刀杆使用寿命不一致的问题。
本发明的附图为：硬质合金螺丝刀头及螺丝刀杆体的结构示意图图中：1、螺丝刀头     2、螺丝刀杆体
本发明的具体实施例如下：螺线刀头1采用YG系列硬质合金制成，YG系列硬质合金的强度可达1700-2600N/mm2，且螺丝刀头1最好选用YG20或YG20C材料制成；螺丝刀头1采用粉末冶金的方法制成十字形、一字形、方形、星形等，螺丝刀头1的尾部可制成凸头结构，螺丝刀杆体2的外端头制成与其相匹配的凹槽式结构，螺丝刀头1与螺丝刀杆体2嵌插后焊接成一体。螺丝刀头与螺丝刀杆的连接方式还可为螺纹连接。
