Abstract

用于书写,绘图的铅笔,在削切过程中,能将铅芯锉磨成所需要尖度,是一种铅笔削锉刀。
该方法在削锉铅笔时,在不需要垫片情况下,削锉刀能很快地完成铅笔所需要的铅芯尖度,而不会产生铅笔芯折断现象。

Description

本实用新型涉及一种削笔刀,特别是一种铅笔削锉刀。
通常的削笔刀,在进行削笔时,虽然能够使铅笔削至所要求的尖度。但在削笔过程中有这样的问题,由于铅笔有各种软硬的铅芯,往往铅笔芯在削屑过程中用力不当使铅芯折断,这样影响削笔的效率。同时由于在削笔过程中为了加快削笔的进程,使之达到使用要求的铅芯尖度,有一种习贯方法是将铅笔放置在一个衬托物件(垫片)上进行削笔,虽然这样也能够完成所要求铅芯的尖度,但它需要有一个衬托物件。如利用桌面作衬托物件,这样容易使桌面产生许多刀痕,既不文雅也不卫生。
本实用新型的目的是提供一种铅笔削锉刀,它不但能高效地完成削笔所要求的铅笔芯尖度,而且在削笔过程中不需要类似衬托物件,也不存在产生使铅笔芯易折断的现象。
实用新型是这样实现的:在原削笔刀的刀面上轧制成类似钢锉的平面形式。
本实用新型因为只需在原削笔刀上经过轧压工序就能形成钢锉面,所以工艺和结构很简单。同时铅笔削锉刀是削锉铅笔之类柔软的物质,所以对采用的材料没有特殊要求。
图1是该铅笔削锉刀的正视图。
在削笔过程中,刀刃〔1〕将铅笔的木质部分及铅芯削成大致的形状,然后在钢锉面〔2〕上面进行锉磨,从而使铅笔得到所要求使用的铅芯尖度。
