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. Because 3D printing can be produced according to the design, more and more fasteners are produced using 3D printing technology. However, the wear resistance of fasteners produced by 3D is not high, and the wear resistance directly affects the quality of the equipment. service life

Embodiment 1

[0052] A method for manufacturing wear-resistant fasteners using 3D printing technology, the specific steps are:

[0053] (1) Build a 3D model of the internal workpiece in the computer. The 3D model is 0.5mm thicker than the outer layer of the entity, and then it is decomposed by the computer layer by layer to form a series of frontal plan views with serial numbers from top to bottom, and generate each frontal plan view. At the same time, a corresponding inverse plan is generated, that is, each layer gets the positive and negative graphics.

[0054] (2) Inject hot-melt powder into the 3D printer for printing or use a 3D printer with hot-melt powder to print.

[0055] (3) The positive and negative graphics generated by the computer are converted into light beams carrying positive and negative graphics information by the signal conversion device.

[0056] (4) Part of the photosensitive drum in the 3D printer is charged to obtain a potential, and scanned by the light beam carrying the po...

Abstract

A method for manufacturing an abrasion-resistant fastening piece through the 3D printing technology comprises the steps that computer modeling and layer-by-layer cutting are carried out; graphs are converted to light beams with graph information; a photosensitive drum is charged to obtain electric potential, and an electrostatic latent image is formed through light beam scanning; the electrostatic latent image passes through a magnetic brush and attracts powder to from an internal component; the surface of the internal component is processed; printing steps are executed repeatedly to form an external component; the outer surface is processed. The fastening piece made through the method has the advantages of being accurate in size, strong in abrasion resistance, and long in service life.
