卡断剪
一、 设备用途
卡断剪位于预精轧机组和精轧机组入口处,用于在轧制过程中发生事故时紧急切断并阻止来料进入预精轧和精轧机,以保护轧机设备。
二、主要技术性能
剪切温度: >950℃
剪切用气缸: φ100/φ32×240
气缸工作压力: 0.4~0.6MPa
三、设备组成和结构特点
卡断剪由底座、剪切本体、气缸等组成,剪机为气动控制的双刃卡断剪,一把刀在轧件上方,另一把刀在轧件下方。当出现事故时,气缸动作,通过连杆机构驱动上、下连杆使剪刃闭合,两个剪刃同时与运行着的轧件接触,通过轧件运行将其拉断。卡断剪底座为焊接结构。
四、润滑、压缩空气
卡断剪剪刀架轴处采用含油轴承,其余采用手动干油润滑,定期给油。
卡断剪气缸用压缩空气由车间统一供给,压缩空气的压力为0.4~0.6Mp。
Gripping shear
The function of the gripping shear
The gripping shear is located in the entrance of the pre-finishing mill and finishing mill, it is used to protect the pre-finishing mill and finishing mill by cutting off the rolled piece and stop further feeding into the mill once there is an operation failure.
Main technical performance
Steels for shearing | General Carbon Steel, Low-alloy steel |
Shearing temperature | >950℃ |
Shearing cylinder | φ100/φ32×240 |
cylinder working pressure | 0.4~0.6MPa |
Equipment composition and structural characteristics
The gripping shear is composed of support base, main machine of cutting and cylinder, cutting machine is two spindle stuck shear that controlled by pneumatic, one is on top of rolling parts and the other is under the rolling parts, when accident occurs, cylinder moved through the closed sword by promote upper and lower connecting rod, these two swords connected with the moving rolling part and cut down it.
The support base of gripping shear is weld structure.
Lubrication and air compression:
The frame axis of gripping shear adapt oil bearing, the others used manual glycerol lubrication to offer the oil regularly.
The compressed air used in cylinder of the gripping shear is supplied by workshop, the pressure is 0.4~0.6Mpa.
