Abstract

The invention provides a rapid forming method combining an electrostatic spinning technique and a device. The method comprises the following steps of: adding a spinning medium into a spinning medium control device, and adjusting the flow of the spinning medium to ensure that the spinning medium uniformly flows out of the tail end of a capillary tube; inputting a plane program of a product platform into a computer, and raising the product platform to a working position; raising a point electrode saddle, and adjusting the height of the point electrode saddle and an output voltage of an electrostatic generator according to requirements on the size of silks ejected by the capillary tube; and when the adjustment is stable, cleaning the product platform, and then starting the electrostatic generator, a product platform motion system and a computer running program to stack fused fibers into needed shapes on the product platform. The electrostatic spinning technique is applied to the rapid forming method, has a significant effect on production of micro parts, and has quick forming speed, flexible processing control and wider adaptation range for the production of quick forming products with general sizes.

Description

technical field [0001] The invention relates to a method and a device for manufacturing tiny parts by electrostatic spinning technology, and belongs to the technical field of rapid prototyping. Background technique [0002] Rapid prototyping technology (RP technology for short) is to use the principle of layer-by-layer accumulation of materials to manufacture products. Rapid prototyping technology integrates advanced technologies such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer numerical control (CNC), precision servo drive and new materials, and is considered to be a major breakthrough in the manufacturing field in the past 20 years , is one of the research hotspots in the field of advanced manufacturing. [0003] At present, there are many kinds of rapid prototyping technologies, such as light solidification method (SLA), lamination method (LOM), selective laser sintering method (SLS), fused deposition method (FDM), mask curing method (SGC...
