Embodiment

[0035] Using the method of combination of virtual and real, with thermo-mechanical coupling or inherent strain method as the core, and the actual process and structure as the auxiliary, the structure is printed in the virtual environment, and the problems of structural deformation and cracking in the printing are predicted and the results are adjusted to avoid quality problems. To solve the problem, realize the one-time molding of structural parts printing.

[0036] (1) Inner runner structure design and process design

[0037] On the basis of the original mechanical processing model, according to the 3D printing manufacturing characteristics and process constraints, the structural design is carried out with the goal of realizing the function of the inner runner assembly block. The specific method is as follows:

[0038] 1. Make the path of the original inner flow channel as parallel as possible to the geometric envelope length of the structural part. The diameter of the narro...

Abstract

The invention discloses a structure based on a narrow inner flow channel. The structure comprises an inner flow channel gathering block (1), the inner flow channel gathering block (1) is provided with a narrow inner flow channel (2), the structure is characterized in that the cross section of the narrow inner flow channel (2) of the inner flow channel gathering block (1) is rhombic, and each angle range of two vertex angles in the middle of the rhombic cross section in the direction perpendicular to the printing direction is 90-160 degrees. The structure is ingenious in design, overcome the problem that the narrow inner flow channel (2) is unsmooth due to the fact that remnants exist in the narrow inner flow channel (2) caused by material reduction machining in the prior art is solved.

Description

technical field [0001] The invention relates to a structure and a process method of a narrow and complex inner flow channel, which can be used in the manufacture of various narrow inner flow channel products. Background technique [0002] The present invention proposes a narrow inner runner design and 3D printing manufacturing method based on technological process simulation. Products with a narrow inner runner structure are mostly used for power system fuel drainage and mold cooling. [0003] It solves the problem that the existing narrow internal flow channel is circular and the design is restricted by the processing technology. The forming of the internal flow channel is realized by drilling holes in the solid metal block by means of material reduction. The structure is relatively bulky and from the perspective of fluid mechanics From the point of view, the machining method makes abrupt corners between adjacent flow channels, resulting in poor flow or stagnation of the li...
