Abstract

The invention discloses an electric arc adding and milling device belonging to the technical field of electric arc adding. The electric arc adding and milling device comprises an electric arc adding unit and a milling unit, wherein the milling unit comprises a milling head; the milling unit is connected with the electric arc adding unit; and the electric arc adding unit comprises a welding gun, a supporting plate, a slide block, a fixing groove, a fixing plate, a stepping motor and a lead screw, wherein one end of the welding gun is fixed together with the slide block, the other end of the welding gun passes through a through hole of the supporting plate, both the supporting plate and the fixing plate are fixed together with the stepping motor, the fixing groove is fixed together with the fixing plate, an output shaft of the stepping motor is connected with the lead screw, and the lead screw passes through a threaded through hole formed in the slide block. The electric arc adding and milling device can be used for realizing additive manufacturing and cutting at one step, so that workpieces are more precisely machined, and the using requirement is met.

Description

technical field [0001] The invention belongs to the technical field of arc material addition, and more specifically relates to an arc material addition and milling processing device. Background technique [0002] Arc additive manufacturing technology is a process of 3D forming of metal parts (WireArc Additive Manufacturing, WAAM) using the arc fuse process, that is, using argon arc welding arc as the heat source, melting the metal wire and depositing it layer by layer to create a product close to the product design Three-dimensional metal blanks with required dimensions. [0003] Compared with other metal additive manufacturing technologies, arc additive manufacturing technology has less investment in equipment (only welding power supply, motion system and control system are required), high manufacturing efficiency (up to several kilograms per hour additive speed), and equipment operation Stable, low operating cost (because the electric-arc conversion rate is more than 85%,...
