specific Embodiment approach

[0030] Step 1: Take out the insulator string, cast the insulator string into shape, preheat the surface of the power fittings, use a ray stress tester to analyze the residual stress of the microstructure of the cladding layer, and obtain the performance of the power fittings, Internal structure parameters, draw the three-dimensional model of the ball head, ball socket, bowl head hanging plate, and ball head hanging ring in the computer, and generate the three-dimensional CAD model of the ball head, ball socket, bowl head hanging plate and ball head hanging ring in the computer After the 3D model is generated, the files converted into STL format are respectively imported into the 3D droplet printer.

[0031]Step 2: Use the 3D droplet printer to make the 3D CAD model of the part, then slice and layer the model according to a certain thickness, convert the 3D information of the part into a series of 2D contour information, and set the 3D industrial computer on the side of the drop...

Abstract

The invention discloses an integrated overhung composite insulator string and a method for printing a composite insulator string connecting metal tool by using 3D. The method comprises the following steps of: firstly, generating a three-dimensional CAD (Computer-Aided Design) model of a part in a computer, and printing the three-dimensional CAD model by utilizing a 3D molten-drop printing machine; then slicing up and layering the model according to a certain thickness, converting the three-dimensional information of the part into a series of two-dimensional profile information; melting down metal by using a crucible, and enabling the molten metal to flow out of a nozzle to form molten drops; then accumulating the molten drops layers by layer according to the two-dimensional profile information under the control of the computer so as to obtain a three-dimensional entity part or a part in similar shape. After the method is adopted, a ball-socket series of metal tools is shaped for once directly through the molten-drop 3D printing machine, the connecting cooperation is more reliable and more stable, secondary installation is unnecessary, and the production efficiency is improved; meanwhile, the efficiency of the site construction is provided, and a great influence to the construction of a high-voltage overhead power line is generated.

Description

technical field [0001] The present invention relates to the field of electrical equipment processing, and in particular to a method for manufacturing and forming an integrated composite insulator string and a hanging composite insulator string based on droplet 3D printing technology and traditional manufacturing. Background technique [0002] 3D printing (3D printing), also known as additive manufacturing technology, appeared in the mid-1990s. Its source can be traced back to rapid prototyping technology (Rapid Prototyping, RP). From the development of 3D computer-aided design (3D CAD), people hope to directly convert design into physical objects conveniently. [0003] With the continuous progress of science and technology, 3D printing technology is becoming more and more mature, and 3D printing technology has become the core technology of high-tech manufacturing. The most cutting-edge and popular 3D printing "metal droplet deposition technology" in the world today does not...
