Embodiment 1

[0030] Such as image 3 As shown, a multi-zone continuous molding additive manufacturing laser molding equipment, taking its four-zone front view as an example, includes a molding chamber 19 and multiple molding shafts corresponding to it, and each molding shaft corresponds to a circular molding area 2, 8, 28, 32, each forming area has its own corresponding laser system (take area a laser system 18 as an example). A rotating shaft 4 is installed in the middle of a plurality of forming areas, and the powder spreading mechanism 6 of a multi-scraper module (taking 11 as an example) is housed on the rotating shaft 4 . When working, the powder spreading mechanism 6 rotates 90° every time to complete the powder spreading requirements of one layer of the four forming areas, and the four forming areas carry out the laser forming process at the same time. When any forming axis is formed, the corresponding forming axis can be replaced independently Warehouse (take the 22-bit forming wa...

Embodiment 2

[0050] A kind of multi-area continuous forming additive manufacturing laser forming equipment of the present invention, taking its two-area and three-area forming as an example (such as Figure 1a , 1b ), its function is as follows:

[0051] The overall operation function is as in Example 2. Due to the different forming areas, the corresponding powder spreading devices have different structures. The inner pipeline of the air outlet has two forming areas, powder feeding port, powder collecting port and air inlet, and the powder spreading device completes a laser forming and melting process every time it rotates 180°;

[0052] Further, the three-area powder spreading device is Y-shaped, with three scraper modules, three air outlets, and corresponding inner pipelines of the three air outlets. The forming area, powder feeding port, powder collecting port, and air inlet are all Three, the powder spreading device completes a laser molding and melting process every time it rotates ...

Abstract

The invention discloses multi-area continuous forming additive manufacturing laser forming equipment. The multi-area continuous forming additive manufacturing laser forming equipment comprises a forming chamber and a plurality of forming shafts corresponding to the forming chamber. Each forming shaft corresponds to one circular forming area in the forming chamber. Each forming area is provided with a respectively-corresponding laser system. A rotation shaft is arranged among the multiple forming areas and provided with a powder paving mechanism provided with a plurality of scraper modules. Themulti-area continuous forming additive manufacturing laser forming equipment solves the technical problems that according to existing equipment, production of single forming areas can only be conducted, the equipment cannot continuously work, and accordingly the workpiece forming technology period is long, and a certain reference value is achieved for promoting development of 3D printing intelligent equipment with assembly line type technology production capability.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing equipment, and in particular relates to an additive manufacturing laser molding equipment with a multi-region continuous molding device. Background technique [0002] The molding raw materials of additive manufacturing technology are usually powder, silk, chemical liquid, etc., and the mainstream technology in industrial applications is to use laser or electron beam as the energy source to melt or bond the powder, such as SLM, SLS, LSF, For technologies such as EBM, the raw materials are powder materials of tens to hundreds of microns. During the molding process, the powder is evenly spread on the molding surface by the powder supply mechanism and the powder spreading mechanism, and then the powder in a specific geometric shape area on the surface is melted by using an energy source such as a laser, resulting in a metallurgical bond, and finally the three-dimensional molding of the ...
