Abstract

The invention relates to a bar stirring friction additive manufacturing device and method. The bar stirring friction additive manufacturing device comprises a frame. The stirring friction assembly comprises a transmission mechanism, a hollow rotating shaft mechanism and a forging sleeve, a penetrating shaft hole is formed in the hollow rotating shaft mechanism, the transmission mechanism and the hollow rotating shaft mechanism are installed on the frame, the transmission mechanism drives the hollow rotating shaft mechanism to rotate relative to the frame, and the end, extending out of the frame, of the hollow rotating shaft mechanism is connected with the forging sleeve. The feeding assembly comprises an ejector rod mechanism and a loading mechanism, the ejector rod mechanism is installed on the frame relative to the hollow rotating shaft mechanism, the loading mechanism is arranged between the ejector rod mechanism and the hollow rotating shaft mechanism, a through discharging port is formed in the loading mechanism, the loading mechanism comprises a pushing part arranged corresponding to the discharging port, and the ejector rod mechanism, the discharging port and the shaft hole are coaxially arranged. The bar is used as an additive medium, plasticizing is fast, plasticized materials are easy to control, continuous feeding of the bar is achieved, operation is easy and convenient, reliability is high, the additive efficiency is high, and the effect is good.

Description

Technical field [0001] The present invention relates to the field of friction additive technology, in particular refers to a bar stirring friction additive manufacturing apparatus and method. Background [0002] Additive manufacturing technology is the use of continuous layered printing and bottom-up layered stacking, and finally form a three-dimensional solid technology, compared to the traditional turning and milling and other subtractive processing technology, with the advantages of reducing material waste, shortening the processing process, improving processing efficiency, etc., and the metal parts obtained by additive have better mechanical properties, so metal additive manufacturing technology has broad application prospects and is one of the key technologies in the field of intelligent manufacturing. [0003] Additive friction stir deposition (AFSD) manufacturing technology is an emerging metal additive technology developed based on stirred friction welding technology, the...
