Daily maintenance and upkeep of hot-rolled pulleys
Hot rolled pulleys are primarily manufactured using the hot rolling process. This equipment is a replacement product of cast pulleys and double spoke plate pulleys. Hot rolled pulleys are not only light in weight and good in quality, but also have high hardness and wear resistance. They also look more concise and beautiful, about 40% lighter than cast slide pulleys of the same specification.
There are several requirements to pay attention to during the daily maintenance of hot-rolled pulleys:
Main functions and material matters of crane pulleys
In cranes, the main function of pulleys is to thread and wind steel wire ropes. Pulleys are divided into movable and fixed pulleys based on whether the central axis is moving or not; According to the manufacturing method, it is divided into cast iron pulleys, cast steel pulleys, welded pulleys, nylon pulleys, and aluminum alloy pulleys. Cast iron pulleys, including gray cast iron (HT1533) pulleys and ball plug cast iron (QT4010) pulleys. Grey cast iron pulleys have good technological performance, have little wear on steel wire ropes, but are fragile, and are mostly used in light and intermediate operation levels; Ductile iron pulleys have higher strength and impact toughness than gray iron, so they can be used in heavy-duty operations.Causes of overheating in piston rod machining
Causes of overheating in piston rod machining
(1) The piston rod and the ferrule joint are tilted during installation, causing some parts to rub against each other, and adjustment should be carried out immediately;
Piston rod design considerations
Piston rod is a connecting component suitable for piston rod work, most of which are used in hydraulic cylinders and cylinder fitness exercise components. It is a fitness exercise component with frequent fitness exercises and high technical standards. Taking the oil pressure cylinder as an example, it is composed of several parts: cylinder liner, piston rod, piston rod, and bearing end cap.
1. Use of machinery and equipment Product workpiece standards.
How to deal with the fracture of piston rod during machining?
The piston rod is processed by rolling, which enhances the corrosion resistance of the surface and delays the generation or expansion of fatigue cracks, thereby enhancing the fatigue strength of the cylinder rod. Through rolling forming, a cold work hardening layer is formed on the rolling surface, reducing the elastic and plastic deformation of the contact surface of the grinding pair, thereby enhancing the wear resistance of the surface of the cylinder rod, while avoiding burns caused by grinding.
Routine maintenance of piston rod equipment
1. Check the integrity of the equipment, whether accessories are missing, and all tools and accessories should be placed and stored neatly.
