Description

technical field [0001] The invention relates to the field of precision machining of inner flow channels, in particular to a pressurizing container, a supercharger, a smoothing device and a method for pressurizing hydraulic oil. Background technique [0002] Parts with fine and complex inner flow channel structures are widely used in aerospace, shipbuilding, nuclear, automotive, mold and other industrial fields, especially the parts related to fluid power systems often have fine flow channels, deep pores and microscopic components. The complex inner cavity structure, such as the communication between the flow channel and the deep small hole, plays the functions of transporting, exchanging or applying hydraulic pressure to the fluid, such as various types of aviation / aerospace / ship / automotive engine fuel nozzles, heat exchangers, hydraulic components, Oil circuit control throttle, etc. [0003] Process technologies that can process fine and complex inner flow channels include...

Problems solved by technology

[0006] However, the technology that can effectively smooth the surface of the micro-complex inner runner has not yet appeared, so that for the micro-complicated inner runner workpieces manufactured by additive manufacturing, the inner The roughness of the surface generally only has the original average roughness Ra≥6.3μm after additive manufacturing, and there is no optimal surface roughness Ra of the inner flow channel Products less than or equal to 1.6 μm, for the fine and complex inner runner workpieces of laser processing and EDM, there is no product with the optimal surface roughness Ra of the inner runner less than or equal to 0.8 μm; And for the fine and complex inner runner workpieces that are machined, there is no product with the surface roughness Ra of the inner runner less than or equal to 0.4μm, and if the fine and complex inner runner has an S-shaped Complex special-shaped runners such as bends, L-bends, U-bends, and O-bends cannot be realized by machining that can only perform linear feeding, but can only be realized by additive manufacturing. The product with the optimal surface roughness Ra of micro-shaped and complex inner flow channel made of high-quality materials is less than or equal to 1.6 μm
