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
| Steel types be processed |
General Carbon Steel, Low-alloy steel |
| Shear temperature |
>950ºC |
| Shear 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.
