Abstract

一种圆钢轧制用倍尺飞剪刀片,包括刀片,刀片设有安装孔,其特征是,刀片的一端开有弧形槽,弧形槽的底部为三角弧形斜面。本实用新型的圆钢轧制用倍尺飞剪刀片,使用时,将两块刀片分别并列安装在轧机上,圆钢通过两块刀片弧形槽上三角弧形斜面刀口剪切,其优点是,不需要分段轧制,单根坯料直接出成品,减少了通条差造成的头尾公差废品;能减少圆钢头部咬入频次,轧制稳定性增加,事故率降低;刀片呈月牙形,上下刀片合并成圆形,与成品截面一致,利于圆钢断面剪切,剪切断面好于普通刀片剪切。

Description

圆钢轧制用倍尺飞剪刀片
技术领域
本实用新型涉及一种圆钢轧制用倍尺飞剪刀片。
背景技术
轧钢厂圆钢轧制φ38以上规格圆钢时,由于受倍尺飞剪平口刀片剪切方式限制,无法实现倍尺分段剪切。轧制时,需要在成品前设置固定大剪分段剪切,实现分段轧制,此轧制方式,轧线事故率高,同时,不利于成品通条差控制,造成两段成品头尾均带耳子,废品量增加。
发明内容
本实用新型的目的就是提供一种结构简单、使用安全、工作效率高的圆钢轧制用倍尺飞剪刀片。 
本实用新型的圆钢轧制用倍尺飞剪刀片,包括刀片,刀片设有安装孔,其特征是,刀片的一端开有弧形槽,弧形槽的底部为三角弧形斜面。
本实用新型的圆钢轧制用倍尺飞剪刀片,使用时,将两块刀片分别并列安装在轧机上,圆钢通过两块刀片弧形槽上三角弧形斜面刀口剪切,其优点是,不需要分段轧制,单根坯料直接出成品,减少了通条差造成的头尾公差废品;能减少圆钢头部咬入频次,轧制稳定性增加,事故率降低;刀片呈月牙形,上下刀片合并成圆形,与成品截面一致,利于圆钢断面剪切,剪切断面好于普通刀片剪切。
附图说明
图1为本实用新型的结构示意图;
图2为图1中A-A剖示图。
具体实施方式
一种圆钢轧制用倍尺飞剪刀片,包括刀片1,刀片1设有安装孔2,其特征是,刀片1的一端开有弧形槽4,弧形槽4的底部为三角弧形斜面3。
