Abstract

The invention discloses a laser additive manufacturing forming method of a static mixer. A shell is included, a penetrating through hole is formed in the shell, and a plurality of locking grooves are formed in one end of the shell in the circumferential direction. A plurality of W-shaped elements are fixedly connected in the through hole. The shell and each W-shaped element each consist of an inner core and an outer shell. The overall model of the static mixer is decomposed into an outer shell and an inner core, different printing parameters are adopted for printing the upper surface, the lower surface, the main body and the contour, and the printing efficiency can be considered while low-angle and cantilever structure printing is met. A second phase material is added into a metal powder material according to a certain proportion, so that the material forming performance is improved, the precision of the product is improved, and meanwhile, the strength, hardness and wear resistance of the product are enhanced.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a laser additive manufacturing molding method for a static mixer. Background technique [0002] Static mixer is an advanced unit equipment with moving parts inside. It mainly uses fluid flow and internal unit to realize the mixing of various fluids. It is widely used in plastics, chemical industry, medicine, mining and metallurgy, food, daily chemical, Pesticide, cable, petroleum, paper, chemical fiber, biology, environmental protection and other industries; in order to improve the mixing capacity of the static mixer, its structural design will be optimized according to the fluid characteristics, resulting in a complex final structure. The traditional processing methods are mostly to split the complex structure layer by layer, mechanically process layer by layer, then stack the multi-layer structure according to certain rules, and combine them by welding and other methods. The stackin...
