Micro-nano nozzle drawing-forging device and method integrating drawing and forging

Abstract

The invention discloses a micro-nano nozzle drawing-forging device and a method integrating drawing and forging. The device comprises a base and a backing plate, wherein a microneedle clamping mechanism, a heating wire clamping mechanism and a drawing-forging needle moving mechanism are arranged on the backing plate; the microneedle clamping mechanism is arranged on the upper part of the backing plate and is used for clamping one end of a glass tube; the heating wire clamping mechanism is arranged in the middle part of the backing plate and is used for heating the glass tube; the drawing-forging needle moving mechanism is arranged on the lower part of the backing plate, and is used for clamping the other end of the glass tube and driving the glass tube to move so as to realize a drawing process. Compared with the prior art, the device has the characteristics of integration of drawing and forging, simple structure, convenience in installation, easiness in use, and the like; the reliability and the accuracy in a micro-nano nozzle drawing-forging process are improved; the problems that the micro-nano nozzle caliber is not easy to control, the shape change is non-uniform, the time and the labor are wasted, the product qualification rate is low and the like during a traditional drawing process are solved; the device and the method are suitable for manufacturing mass glass micro-nano nozzles in a lab and a factory.

Description

technical field

[0001] The invention relates to a micro-nano nozzle drawing forging device and method integrating drawing and forging, and belongs to the field of glass micro-nano nozzle production. Background technique

[0002] 3D printing technology has created a higher demand for nozzles, which is a great constraint on the printing range of printers. 3D printers with finer nozzles will undoubtedly play a greater role, such as MEMS production, genetic engineering, tissue culture, chip printing, display screen printing and other fields. Therefore, the development of finer micro-nano nozzles will help expand the application field of 3D printer nozzles, and can promote the development of China's manufacturing industry to cater to "China Smart Manufacturing 2025".

[0003] At present, the common micro-nano nozzle manufacturing devices include horizontal and vertical needle pulling instruments and forging needle instruments. There are horizontal and vertical needle pulling ins...
