Problems solved by technology

[0002] With the continuous advancement of science and technology in different fields, human beings have made breakthroughs in various fields, and more and more equipment is used. The main purpose of fasteners is to connect various components and play a role in the connection of equipment. It plays a very important role. With more and more equipment, there are more and more types of fasteners. For large quantities of standard fasteners, they can be directly produced in batches, but for small batches of fasteners, equipment batches Production is very wasteful. Since 3D printing can be produced according to the design, more and more fasteners are produced using 3D printing technology. The performance of fasteners produced by 3D technology is often not good enough. Extremely high, if a layer of coating treatment is applied on its outer surface, the performance of the fastener can be greatly improved

Embodiment 1

[0036] A 3D printing production method of a coated fastener, the specific steps are:

[0037] (1) Establish the 3D model of the workpiece in the computer. The 3D model is 0.5mm thicker than the outer layer of the solid, and then decomposed by the computer layer by layer to form a series of front plans with serial numbers from top to bottom. When generating each front plan A corresponding anti-planar graph is generated, that is, two graphs of positive and negative are obtained for each layer.

[0038] (2) After injecting NdFeB powder into the 3D printer, print or use a 3D printer with NdFeB powder to print; the components and mass percentages in the NdFeB powder are: NdFeB powder 90%, binder 8%, processing aid 2%; the components and mass percentages of the binder are: vinyl acetate-ethylene copolymer emulsion: 10%, polyvinyl alcohol: 5%, rust inhibitor: 0.5%, preservative: 0.5% , defoaming agent: 1%, all the other are water; The rust inhibitor is borax; The preservative is pot...

Abstract

A 3D printing production method of a coated fastener particularly includes the steps that computer modeling and layer-by-layer segmentation are conducted; graphs are converted into light beams with graphic information; photosensitive drums are charged to acquire electric potential, and static latent images are formed through light beam scanning; the static latent images adsorb powder to form internal components through a magnetic brush; the surfaces of the internal components are processed; coating is conducted; a coated layer is processed. The fastener produced through the 3D printing production method has the advantages of being high in production accuracy and excellent in anti-corrosion performance.
