Abstract

The invention relates to a fine-structure tooling based on 3D printing composite manufacturing, and relates to the technical field of 3D printing equipment. The invention adopts the idea of ​​laser selective melting and composite manufacturing of fine structures on traditional structural parts, designs the tooling of the manufacturing platform, and realizes fast clamping and positioning of the tooling. The original processing plan needs to print out the substrate synchronously to meet the requirements of the subsequent machine to add the card, and the forming efficiency is low. The average printing time of a single product is about 2 hours; the composite manufacturing idea is adopted to process the machine-added card in place in advance, and the installation On the special tooling, this avoids the printing of the machine-added chuck, greatly reduces the printing time, improves the efficiency, and the base of the chuck can be reused, which greatly saves the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a fine structure tooling based on 3D printing composite manufacturing. Background technique [0002] 3D printing technology is a technology based on the principle of discrete accumulation, integrated computer graphics processing, digital information and control, electromechanical control technology and material technology, and adopts the method of accumulating materials layer by layer to realize the technology of rapid free forming of parts. 3D printing technology can greatly reduce the complexity of product manufacturing and expand the scope of manufacturing. However, the efficiency and cost of laser selective melting for some key structural parts in aerospace and other fields still cannot meet the development needs of model products. Combining 3D printing with traditional manufacturing, it has become a trend to compound complex and fine structures on traditional c...
