Abstract

本实用新型公开了一种纸板钩槽机的钩槽刀,包括刀片和固定刀片的刀架,其特征在于:所述刀片为板条形刀片,刀片设有两片,两刀片在刀架上呈V型角固定设置,两刀片的刀尖相互贴近,刀片在高度方向上与垂直面具有一斜角,斜角a为8-15°之间。上述结构的钩槽刀代替传统V型刀片的钩槽刀,不仅提高切削速度,而且刀具使用寿命长,换刀磨刀方便。

Description

纸板钩槽机的钩槽刀
技术领域:本实用新型涉及一种用于纸板开槽的纸板钩槽机,具体涉及一种纸板钩槽机的钩槽刀。 
背景技术:纸板钩槽机用于工业纸板、灰纸板、密度板等各种不同纸板的开槽,然后这些开槽后的纸板会被应用于各种礼品包装盒的制作。现有技术的纸板钩槽机,其钩槽刀采用的是V型刀片,V型刀片结构复杂,刀片磨削后切削角受到较大限制,所以切削速度较慢,刀具容易磨损,刀具使用寿命短,换刀磨刀不太方便。 
发明内容:针对现有技术的不足,本实用新型的目的旨在提供一种代替传统V型刀片,提高切削速度,刀具使用寿命长,换刀磨刀方便的纸板钩槽机的钩槽刀。 
本实用新型采用的技术方案是:纸板钩槽机的钩槽刀,包括刀片和固定刀片的刀架,其特征在于:所述刀片为板条形刀片,刀片设有两片,两刀片在刀架上呈V型角固定设置,两刀片的刀尖相互贴近,刀片在高度方向上与垂直面具有一斜角,斜角a为8-15°之间。 
两刀片在刀架上呈V型角设置,不仅可以代替传统V型刀片在纸板上开出V型槽,而且,上述组合刀片可以磨出锋利的切削角,开槽时刀片首先从槽的两侧切入,最后由两刀片的刀尖将纸板的V型槽钩出,这样刀尖部位不易损坏,大大提高切削速度和刀具寿命,刀具不易磨损,换刀磨刀也方便。 
附图说明:
图1为本实用新型的结构图 
图2为图1的M向视图 
图3为图1的A-A视图 
具体实施方式:如附图1、2、3所示,该纸板钩槽机的钩槽刀,包括刀片1和固定刀片1的刀架,刀架由刀柄4、刀头3和压板2固定连接而成,所述刀片1为板条形刀片,刀片设有两片,两刀片在刀架上呈V型角固定设置,两刀片的刀尖相互贴近,刀片在高度方向上与垂直面具有一斜角,斜角a为8-15°之间。 
上述钩槽刀在对纸板5进行开槽时,纸板5从刀片底部往上,刀片首先从槽的两侧切入,最后由两刀片的刀尖将纸板5的V型槽钩出,刀尖部位不易损坏,大大提高切削速度和刀具寿命,刀具不易磨损,换刀磨刀也方便。
