What are the functions of the copper sleeve on the hot die forging press? The following copper sleeve manufacturers will introduce to you.
When the hot die forging press works, the motor torque is transmitted from the small pulley to the large pulley on the drive shaft through the V-belt, and then the torque is transmitted to the large gear on the crankshaft through the small gear at one end of the drive shaft. The pulley is fixed with a floating insert friction clutch. The other end of the crankshaft is a floating insert brake. The middle of the crankshaft is equipped with a connecting rod. The connecting rod and the slider are connected by a tension brake, a tension lever and a pressure pin. When the press is working , The clutch and the brake are aired at the same time. Because the volume of the brake cylinder is smaller than the volume of the clutch cylinder, the clutch is connected only after the brake is released, driving the crankshaft to rotate, and driving the slider to move vertically in the body guide through the connecting rod.
During the use of the hot die forging press, due to the failure of the automatic oil separator detection device, there is a lack of oil between the crankshaft journal and the sliding bearing to form dry friction, causing local wear and contact fatigue, and the surface of the copper sleeve is partially peeled off, forming a gradual Type friction damage, causing loss to production.
The copper sleeve is a part or component that supports the shaft. The journal and the bearing bush are in surface contact, which belongs to sliding friction. Compared with rolling bearings, it has large load-bearing capacity, shock and vibration resistance, and is widely used in high-speed, high-power, and low-speed and heavy-duty machines; smooth running performance and high rotation accuracy can be obtained, so it is often used as a metal cutting machine tool Spindle bearings. The split structure is convenient for installation, maintenance and debugging, and becomes the only feasible way for large-scale equipment to choose the support method; in addition, the structure is simple, the cost is low, and it can be operated for a long time without adding lubricant. If you have any questions, you can consult the copper sleeve manufacturer!
