Hydraulic manifold block is a device that integrates multiple hydraulic components (such as hydraulic valves, hydraulic pumps, hydraulic cylinders, etc.) on a block structure through oil channels to realize various functions of the hydraulic system. It is usually composed of blocks, various mounting holes, oil channels and connection interfaces. The blocks are generally made of high-strength aluminum alloy or carbon steel materials to ensure its strength and sealing. The mounting holes are used to install hydraulic components, the oil channels are processed in the blocks according to the design requirements of the hydraulic system, and the connection interfaces are used to connect with external hydraulic pipelines, oil tanks and other components.Through the internal oil channels, according to the pre-designed hydraulic circuit, the hydraulic oil is transported from the hydraulic pump to each hydraulic component to achieve the control of the pressure, flow and direction of the hydraulic oil, thereby driving the actuators such as hydraulic cylinders or hydraulic motors to complete various actions to meet the working requirements of different mechanical equipment.

Raw material preparation: Select raw materials with specific tissues, and through the forging process, give the material good internal structure and mechanical properties, laying the foundation for subsequent processing. ​

Rough processing stage: Use rough milling processing methods to quickly remove most of the excess, initially shape the outline of the hydraulic integrated block, and determine the approximate size.

​

Heat treatment process: perform quenching and tempering treatment to effectively improve the comprehensive mechanical properties of the material, enhance its strength and toughness, and meet the use requirements. ​

Semi-finishing process: carry out semi-fine processing to further refine the dimensions of each part and prepare for subsequent key processes.

​

Deep hole processing steps: use deep hole drilling equipment to accurately process deep holes to ensure the accuracy and quality of the holes and meet the functional requirements of hydraulic oil circulation. ​

Drilling and tapping operations: after completing the drilling operation, perform the tapping process to provide standard threaded holes for installing connectors, etc. ​

Surface treatment finishing: polishing is performed at the end to improve the surface finish of the hydraulic manifold, which not only helps to look beautiful, but also reduces fluid resistance and improves overall performance.

Mechanical properties: After quenching and tempering, it has high strength and hardness, tensile strength can reach more than 635MPa, yield strength is not less than 440MPa, and has a certain toughness, and can withstand a certain degree of impact load.

Corrosion resistance: Contains about 13% chromium, has good corrosion resistance in atmospheric environment and some weakly corrosive media, and can form a dense chromium oxide protective film on the surface to prevent further corrosion. However, in some highly corrosive media such as strong acids and strong alkalis, the corrosion resistance is relatively limited.

Machinability: It has good machinability and can be made into parts of various shapes through forging, rolling, cutting and other processing methods. However, due to its high hardness, it is necessary to select appropriate tools and processing parameters during the processing to avoid excessive wear of the tools.

Heat resistance: It has good heat resistance within a certain temperature range and can be used for a long time in an environment below 400℃, and the short-term use temperature can reach about 500℃.

Applications: It is often used to manufacture some mechanical parts that require high strength and hardness, such as shafts, gears, bolts, etc. Its good mechanical properties can ensure that these parts can withstand large loads without deformation or damage during long-term operation.

Through the internal oil channels, according to the pre-designed hydraulic circuit, the hydraulic oil is transported from the hydraulic pump to each hydraulic component to achieve the control of the pressure, flow and direction of the hydraulic oil, thereby driving the actuators such as hydraulic cylinders or hydraulic motors to complete various actions to meet the working requirements of different mechanical equipment.
