Cold shearing machine is a device for shearing and cutting the length of the rolled piece from the cold bed.

　　The cold shear is driven by the top motor through the elastic coupling by the first gear reducer, the big gear sleeved on the crankshaft and the right half clutch fixed on the gear to rotate idly. When the shear starts to work, the roller of the brake device is sucked by the electromagnet. At this time, the left half clutch mounted on the crankshaft with sliding keys is pushed to the right by the spring and combined with the right half clutch. Therefore, the scissors installed at the right end of the crankshaft can obtain straight up and down motion by driving the crankshaft to rotate. 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. When the shearing is finished, the controller automatically operates, the electromagnet is cut off, the roller of the brake device is pulled up and moved under the action of the spring to release the clutch, the crankshaft stops rotating, and the shears are restored to the original highest position under the action of the balanced spring. The cold shear thus realizes the task of shearing the fixed length and the cutting head by circulating and reciprocating.

　　The cold shears of Maanshan Zhicheng Mechanical and Electrical Co., Ltd. are equipped with:

　　Equipped with the advanced pneumatic brake and clutch device in the world, the shearing process is fast, accurate, stable and reliable.

　　Equipped with quick 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 on 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 fasteners.

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

　　It can realize Mechatronics configuration.
