　　The 850 ton cold shearing unit produced by our company has absorbed the advanced technology of foreign countries in recent years, and has re-optimized many key technologies to make it an advanced finishing shearing equipment. Its performance and shearing quality have reached the advanced level of similar products abroad by users, and have been widely praised by users.

　　Characteristics of 850 tons cold shear

　　It is equipped with advanced pneumatic brake and clutch devices in the world to ensure the shearing process is fast, accurate, stable and reliable.

　　Equipped with rapid blade replacement device, the opening, pressing, pushing and resetting of the tool seat are completely driven by hydraulic pressure.

　　The steel pressing device is installed at the feeding side of the cold shear body, and the cylinder pushes down the roll to press the cut material to ensure the smooth cutting of the material and the safety of the operation of the equipment.

　　The transmission part adopts high precision gear transmission, which has smooth transmission and low noise.

　　The main body of the machine tool is gantry type, which has the characteristics of stable performance and low vibration when shearing the rolled piece.

　　Self-contained dry oil, thin oil lubrication system, hydraulic valve platform;

　　Mechatronics configuration can be realized.

　　When 850 tons of cold shears start to work, the roller of the brake device is sucked down by the electromagnet. At this time, the left half of the clutch mounted on the crankshaft with sliding keys is pushed to the right by the spring and combined with the right half of the clutch, thus driving the crankshaft to rotate, and the scissors mounted on the right end of the crankshaft can get up and down straight movement. The upper cutting edge fixed on the scissors moves in a straight line with the scissors. The lower cutting edge is fixed on the frame and does not move. When the upper cutting edge falls down, the cutting of steel is realized.
