Abstract

A current-assisted roll forming device for a large area functional microstructure array relates to a roll forming technology, and is designed to solve the problem that large area functional microstructure array is not easy to be formed. A control cabinet of the device is used to control a driving motor to drive a roller press of the precise microstructure array to complete the forming process of the microstructure array of formed parts; an auxiliary forming power supply is used to output pulsed DC, and the current closed loop is realized by the pulsed DC passing though the roller press of theprecise microstructure array and the formed parts. The current-assisted roll forming device for the large area functional microstructure array has the advantages that the forming load can be reduced,and the device is more suitable for continuous production. By using the Joule heating effect and the electroplastic effect formed by assisted current, plastic forming ability of materials can be improved, the minimum forming size can make a breakthrough, and the problem that the large area functional microstructure array is not easy to be formed can be solved.

Description

technical field [0001] The invention relates to a rolling forming technology. Background technique [0002] Functional microstructure is to manufacture microstructures with different shapes and scales on the surface of objects, so that they have different functions, such as surface heat function, light function, drag reduction function, super-hydrophobic function and video stealth function, etc. Improve equipment and product performance, reduce energy consumption and other functions. With the continuous improvement of the functional requirements of modern equipment and products, the surface functional microstructure has gradually developed from local processing technology to overall design and manufacture. At present, microstructure manufacturing technologies mainly include thermal embossing, rolling and chemical methods. For the metal functional surface microstructure, hot embossing and rolling methods are mainly used. However, the size of the microstructure is very smal...
