We have a large stock of standard galvanized ball head hanging ring, which you are welcome to visit our factory for inspection, shortening the procurement cycle. For special requirements, we can customize production, including ball head diameter, hanging ring hole diameter, connecting rod length, etc. For customized products, we will provide users with detailed dimensional drawings and performance test reports. Mass production will only begin after the product meets the user's requirements.
With years of production experience, we have continuously innovated the production process of galvanized ball head hanging ring, which has led to the current standardized system for the entire process. In the production process, we mainly use forging, combined with precision machining and galvanizing, to ensure stable quality and deliver to users at the lowest price, so that users around the world can use them:
Pre-treatment
The selection of raw materials directly determines the load-bearing capacity. Before production, they must undergo spectral testing and hardness testing to remove impurities from the material and perform surface cleaning, including removing rust, oil, and oxide scale. This can be achieved through sandblasting and acid pickling. The material is then cut into sections according to the required weight and size to ensure it meets production needs.
01
Hot forging
The blank is placed in a heating furnace and the temperature is raised to 1100-1250℃ to put the steel in a thermoplastic state. Then it enters a precision forging press. Different dies are selected according to the different ball heads, connecting rods, and hanging rings required. The blank is formed in one piece through forging, stamping and other methods. During the forging process, the temperature and pressure are monitored in real time to ensure product quality.
02
Precision machining
The surface of the ball head is turned and ground to ensure that the smoothness tolerance of the ball surface is within ±0.02mm and to ensure the fit of the overall structure. Then, the hole diameter of the hanging ring and the thread of the connecting rod are machined to improve the strength and wear resistance of the thread and avoid stripping during hoisting. Precision machining lays a good foundation for installation and use.
03
Galvanizing process
To ensure corrosion resistance, hot-dip galvanizing is used during production. For indoor use, electro-galvanizing can also be selected. The zinc layer adheres strongly to the steel and is not easy to fall off during use. After galvanizing, passivation treatment is performed to form a protective film on the zinc layer surface, which can further improve corrosion resistance.
04
Finished product inspection
The inspection mainly includes the mechanical properties of the galvanized ball head hanging ring, testing the destructive load with a tensile testing machine and matching it with the corresponding model, visually inspecting the appearance to see if the zinc layer is uniform and whether there are any problems such as uncoated areas or scratches on the surface, and packaging the product in pallets and wooden boxes with cushioning materials to prevent damage to the zinc layer during transportation, and including a product instruction manual.
05
Galvanized ball head hanging ring are arguably one of the most important accessories in power transmission lines. Therefore, our factory has very strict requirements for the production process. We pay attention to details in the production of products of different specifications to ensure that the quality meets the requirements. Products that do not meet the requirements will not leave the factory.
Galvanized ball head hanging ring offer numerous advantages in use due to their scientific structural design and sophisticated manufacturing process, primarily in the following aspects:
Superior load-bearing capacity
High-strength steel combined with a reasonable structural design can disperse stress and avoid damage caused by localized stress. The load-bearing capacity covers 0.5-10 tons and can be used in different scenarios. Through a stable and reliable connection, it can maintain a tight connection under dynamic loads such as wind vibration and equipment operation to prevent slippage and ensure project safety.
Corrosion and weather resistance
The zinc layer can effectively isolate the steel from the corrosion of air, moisture, acid and alkali substances. When used outdoors, it can withstand rain, snow and ultraviolet radiation, which can extend its service life. The surface passivation treatment can also slow down the corrosion rate. When used in the seaside, chemical plant and other fields, the service life can still reach 15 years.
Easy installation
The ball joint's spherical design features non-directionality and high deflection, allowing for flexible rotation at multiple angles during use to adapt to different connection angles. It is suitable for various scenarios such as power transmission lines. No complicated tools are required for installation, and it is easy to install and remove. This not only improves installation efficiency but also prevents the loss of parts, bringing convenience to live-line work.
