Abstract

一种伐木锯链刀片,属刀片。刀片的下部为连接板,在连接板有两个圆孔,在一圆孔的上方有一半圆形的缺口,从缺口至刀片边缘有一保护片凸出,在另一个圆孔的上方有一平面,平面的前端为刃口,平面的截面形状为“7”字形,“7”字形的拐角尖为刃尖;拐角外的硬度大于拐角内的硬度,刃口高于缺口对面的保护片。该锯链刀片结构新颖,在锯切木材时其刀片具备自锋利能力,对刃口进行修刃快捷,节省了修刃的耗时,提高了效率,降低了成本。

Description

伐木锯链刀片
本实用新型涉及一种刀片,特别是锯链刀片。
目前,在伐木场伐木时大都使用的弓形往复锯和圆盘形锯,安装在上述两种锯上的锯片上有不间断的齿形刃,在伐木锯切过程中,该锯片的齿形刃被均匀磨削、磨损,齿形刃逐渐圆钝,造成夹锯、出屑不畅,不具备自锋利能力,影响了伐木的速度,对锯片齿形刃进行修刃后锯片才能重新使用,费工、费时。
本实用新型的目的是要提供一种出屑顺畅、具备自锋利能力、对刃口进行修刃快捷的伐木锯链刀片。
本实用新型的目的是这样实现的:刀片的下部为连接板,连接板上有两个圆孔,在一圆孔的上方有一半圆形的缺口,从缺口至刀片边缘有一保护片凸出,在另一个圆孔的上方有一平面,平面前端为刃口,平面的截面形状为“7”字形,“7”字形的拐角尖为刃尖;拐角外的硬度大于拐角内的硬度,刃口高于缺口对面的保护片。
由于采用了上述方案,在刀片刃口的前方有一半圆形缺口,锯切木材时的木屑从此缺口输出,由下一个刀片上的保护片将木屑从锯缝中带出,使锯切后的木屑出屑顺畅;刀片刃口内的硬度低于刀片刃口的硬度,采用该锯链刀片进行锯切木材时,对该刀片的磨损速度产生差别,即刃口的磨损速度慢,刃口内的部分磨损快,使刃口总是处在一种锋利的状态,具备了自锋利能力;当刃口卷边时对刃口进行修刃非常快捷,达到了本实用新型的目的。该锯链刀片结构新颖,在锯切木材时其刀片具备自锋利能力,对刃口进行修刃快捷,增加了刀片的使用寿命,节省了修刃的耗时,提高了效率,降低了成本。
下面根据附图结合实施例作进一步说明。
图1为本实用新型的结构图。
图2为图1的A-A视图。
实施例1:刀片的下部为连接板5,连接板5近似半圆形,在连接板5上有两个圆孔,在一圆孔的上方有一半圆形的缺口3,该缺口3为出屑口,从缺口3至刀片边缘有一保护片4凸出,在另一个圆孔的上方有一平面1,平面1的前端为刃口,刃口一方高于平面1后端,平面1的截面形状为“7”字形,“7”字形的拐角尖为刃尖2,刃尖2向缺口方向凸出,并向“7”字形拐角内方向渐厚,拐角外的硬度大于拐角内的硬度,刃口高于缺口对面的保护片4。
实施例2:实施例1所述为右切刀片,刃口的截面形状呈反“7”字形时为左切刀片,其它与实施例1同,略。
