Process for quickly manufacturing electric power fittings based on 3D printing technology

Abstract

The invention discloses a process for quickly manufacturing electric power fittings based on a 3D printing technology. Drawings of plastic fitting samples and printing procedures are built to form a 3D printing terminal database of plastic metal samples; plastic sample models are obtained through 3D printing; the plastic sample models are placed in a tightly vibrated sand box, are added with dry quartz sand, and are fixed by the dry quartz sand, and meanwhile, a vibration table is vibrated by preset time in the three-dimensional direction, so that the dry quartz sand is fully filled in all parts of the plastic sample models; and the sand box is moved out to a casting station, the surface of the sand box is sealed by a plastic film, the dry quartz sand is bonded by dint of the difference between the atmospheric pressure and the pressure in a casting mold inner shell, and molten metal is cast to generate the replacement process of liquid metal and the plastic sample models to finally form metal castings. The process quickly manufactures requirement-satisfied sample molds by using the 3D printing technology through the advantages of short manufacturing time and simple operation, effectively prevents the problem of weak strength of traditional 3D printing finished products through the combination with a traditional fitting production process, and can be quickly applied to qualified products for power repair.

Description

technical field [0001] The invention relates to a manufacturing process of electric power fittings, which is a process for rapidly manufacturing electric fittings based on 3D printing technology. Background technique [0002] It happens from time to time that spare parts are urgently called for power repairs, and power companies may be in short supply due to untimely replenishment of spare parts or failure to prepare all models; fittings manufacturers have some molds or semi-finished fittings for common spare parts of specific models in response to this situation. Due to economic considerations, not all spare parts are included, especially for some fittings with complex structures and various sizes. Once there is no spare parts mold, it will seriously delay the power recovery time.

Problems solved by technology

[0003] The purpose of the present invention is to overcome the technical problem in the prior art that the maintenance can not be carried out as soon as possible due to insufficient or incomplete spare fittings samples during electric power repairs, and to provide a method that effectively avoids the current 3D printing by combining with the traditional fittings production process. The problem of insufficient strength of the finished product can eventually be obtained in a shorter production time than traditional fittings, and higher strength than contemporary 3D printing products, which can be quickly applied to the rapid production of electric fittings based on 3D printing technology for emergency repairs
