ABSTRACT

[Purpose/significance] In traditional manufacturing process, hydraulic manifold blocks are drilled into blank to form their complex flow channel structure This processing technology is complicated and the efficiency is low. Selective laser melting (Selective laser melting, SLM) is a kind of additive manufacturing technology. Compared with traditional processing technology, it is not sensitive to the complexity of the processed parts. It is especially suitable for machining parts with complex internal structure such as hydraulic manifold blocks. [Method/Process] Therefore, this article proposes an additive manufacturing scheme for rapid-solidifying SLM forming of hydraulic manifold block, introduces the materials required for SLM forming, the method of rapid-solidifying SLM forming, and analyzes the application effect of the new scheme in the additive manufacturing of hydraulic manifold block. [Result/Conclusion] The results show that the rapid-solidifying SLM is insensitive to the internal pore structure of the integrated block, and can accurately design and optimize the complex porous structure of the integrated block. Compared with other additive manufacturing technologies, the forming accuracy is higher. The microstructure and comprehensive mechanical properties of the post integrated block are better, and it has a very broad development prospect.
