Introduction

 

Cold shear refers to the process of cutting a material using a cold shear during the rolling production process. The shearing force of the cold shearing machine is internal force and is not transmitted to the foundation; the action of the tool holder is crank-link type, the structure is relatively simple, and the maintenance is convenient; the electro-hydraulic push rod jaw clutch is used; the cold shear body has sufficient rigidity and has Good overload protection; thin oil lubrication and dry oil lubrication combined with a good lubrication system.

Cold shear is the key equipment used in finishing bar mill shop, when rolled metal out of the bar rolling mill, after the cooling bed, rolled metalhead will be cut, cut tail, and as customer requirements to cut required lengths. Its performance and the rhythm determine the output capacity of the entire hot rolling mill production line.
