Industry Knowledge

What are the materials and manufacturing process of OY116B jack?

The OY116B jack is a high-performance, multi-functional hydraulic jack that is widely used in automobile maintenance, construction sites, bridge construction and other occasions. It is highly praised by users for its excellent quality, stable performance, excellent load-bearing capacity and efficient operating efficiency.

1. Material selection
The OY116B jack is very particular in the selection of materials to ensure the product's durability and safety. The main materials include the following aspects:

Cylinder material: The cylinder is the main part of the jack, usually made of high-strength alloy steel. Carbon steel is usually one of the most common choices because it has good strength and stiffness, and is relatively easy and low-cost to machine. However, carbon steel can be sensitive to corrosion and requires additional protection in wet or corrosive environments. Alloy steel has greater strength and hardness than regular carbon steel, so may be a better choice in applications that require greater durability and load capacity. Alloy steels can also have their composition tailored to specific needs to provide specific properties. Aluminum alloys are lighter than steel and therefore can reduce the weight of the device, which may be an advantageous choice for mobile devices or applications that require hand-holding. However, aluminum alloys may not be as strong as steel and may deform or become damaged under high load conditions.

Piston material: The piston is an important part of the jack responsible for lifting and lowering. It is generally made of wear-resistant and corrosion-resistant high-quality steel. The piston material must have sufficient strength and hardness to withstand the pressure and load of the jack during use. Common materials include high-strength steel, alloy steel, etc. The piston material should have good corrosion resistance, especially if the jack is used in a humid or corrosive environment, to extend its service life. Stainless steel is a common choice. The piston material surface should have good lubricity to reduce friction and ensure smooth movement of the piston. Some materials themselves have good lubricity, such as copper alloys.

Seal material: Seals are key components in the jack to prevent hydraulic oil leakage. They are usually made of high-performance rubber or polyurethane materials. Rubber seals have good elasticity and wear resistance and can withstand a certain amount of pressure and friction. They are usually used for sealing between the piston and cylinder of the jack, and can effectively prevent the leakage of hydraulic oil. Rubber seals also have certain oil resistance and can maintain stable performance in hydraulic oil for a long time. Polyurethane seals have higher strength and wear resistance, and are suitable for high-pressure and high-speed working environments. They are often used in critical sealing areas of the jack, such as oil ports and joints. Polyurethane seals also have good anti-aging properties and can maintain a stable sealing effect for a long time.

Surface treatment: Before surface treatment, the jack first needs to be pre-treated. This includes two main steps: cleaning and rust removal. Cleaning is to remove oil, dust and other impurities on the surface of the jack to ensure that subsequent processing can proceed smoothly. Rust removal is to remove the rust existing on the surface to provide a good foundation for subsequent coating adhesion. After pre-treatment, the jack is surface sprayed. Spraying usually consists of two layers: primer and topcoat. The main function of primer is to enhance the adhesion between the coating and the substrate and prevent the spread of corrosion and rust. The topcoat is responsible for providing an aesthetic appearance and additional protective properties. When selecting a coating, its corrosion resistance, abrasion resistance, and compatibility with the jack material are taken into consideration. After the spraying is completed, the jack will be painted. This step is to place the jack in a high-temperature environment to evaporate the solvent in the paint and solidify the coating, thereby improving the hardness and wear resistance of the coating. The surface of the jack after baking paint treatment will be smoother and brighter, and the coating will be more durable.

2. Manufacturing process
The manufacturing process of OY116B jack is very delicate, which mainly includes the following links:

Casting and forging: Casting is a processing method in which metal is heated and melted, poured into a sand mold or mold, and then cooled, solidified, and cleaned to obtain a casting of the desired shape. In the manufacturing of OY116B jacks, the casting process may be used to produce certain parts with complex shapes, especially those with complex inner cavity structures. The advantage of casting is that it can manufacture parts with complex shapes, and the raw materials are widely available and cheap. However, castings may have coarse grains and relatively low mechanical properties. Forging is a forming process that applies static load to metal materials to cause plastic deformation to obtain the required geometric shape and mechanical properties. In the manufacturing of OY116B jacks, the forging process may be used to manufacture parts that require higher strength and toughness. During the forging process, the metal material is plastically deformed under pressure in the mold, which can refine the grains and improve the strength and toughness of the material. In addition, forged parts usually have higher precision and better surface quality.

Machining: The preparation stage for machining is crucial. At this stage, machinists will carefully inspect and screen the raw materials to ensure that the materials used meet the design requirements and have sufficient strength and toughness. The core link of machining begins. According to the design drawings and process requirements, workers will use various mechanical equipment to precisely process various parts of the jack. These equipment may include digital milling machines, digital lathes, grinders, etc., which enable precise cutting, drilling, milling, and grinding of materials. During the processing process, workers need to strictly control the processing accuracy and surface quality to ensure that each component meets the design requirements. During the processing process, the selection and application of positioning benchmarks are also very critical. Positioning datum is the datum used by the workpiece during processing and assembly. It can ensure that the workpiece occupies the correct position in the machine tool or fixture. Commonly used positioning benchmarks include automatic centering positioning and positioning sleeve positioning. Workers will select the appropriate positioning benchmark according to the specific situation and use corresponding fixtures and tools to fix it to ensure the stability and accuracy of the processing process.

Seal installation: After the cylinder, piston and other components are processed, the seals are installed. This link requires strict control of the size and installation position of the seal to ensure good sealing effect and prevent hydraulic oil leakage.

Assembly and debugging: Assemble the processed parts and conduct strict debugging. During the debugging process, it is necessary to check the lifting speed, load-bearing capacity and other performance indicators of the jack to ensure that the product meets the design requirements.

Inspection and testing: During the manufacturing process, every link is strictly inspected and tested. Including material inspection, dimensional inspection, performance testing, etc. to ensure that product quality meets standards.

Surface treatment and packaging: Finally, the jack is surface treated and packaged. Improve the appearance of the product through sandblasting, painting and other treatments, and perform anti-rust treatment to enhance the corrosion resistance of the product. During the packaging process, shock-proof, moisture-proof and other measures are adopted to ensure that the product is not damaged during transportation and storage.
