Key points of hydraulic valve block technology
1. Design and determine the process plan
This is an important step in the processing of hydraulic valve blocks. It is necessary to determine the process plan based on the specific structure and size of the hydraulic valve block, including the process route, process parameters, tool selection, etc., to ensure high precision and high efficiency of subsequent processing.
2. Milling surface processing
Milling surface processing is one of the key steps in hydraulic valve block processing. It is necessary to select appropriate tools and cutting parameters, control cutting force and temperature, and ensure the flatness, verticality and surface quality of the milling surface.
3. Boring
Boring is another important step in the processing of hydraulic valve blocks. It is necessary to select appropriate boring tools and coolants, control the boring diameter and depth, and ensure the aperture accuracy and surface finish.
4. Grinding
Grinding is the key step in the processing of hydraulic valve blocks. It is necessary to select appropriate grinding stones and grinding parameters to ensure the smoothness and accuracy of the machined surface and avoid grinding heat damage.
5. Electroplating and cleaning
Ultrasonic cleaning must be carried out before and after electroplating to ensure that there is no iron filings and cutting oil residue on the inner wall of the valve hole to ensure the safety of the hydraulic valve.
6. Assembly
Assembly is the last step in the processing of hydraulic valve blocks. It needs to be assembled according to the design requirements, assembly sequence and installation torque, and the assembly quality and performance must be tested and inspected.
Hydraulic valve block machining accuracy requirements
1. Dimensional accuracy: including length, width, height, aperture, etc., generally required to be within ±0.01mm.
2. Geometric accuracy: including verticality, parallelism, coaxiality, roundness, etc., generally required to be within 0.01mm.
3. Surface quality: including smoothness, flatness, absence of cracks, pores, etc., generally required to be within Ra0.4.
4. Sealing performance: It is necessary to ensure good sealing inside the hydraulic valve block to prevent leakage and damage to the equipment.
