Abstract

An induction heating fuse wire and laser compound based additive manufacturing device comprises a bottom plate, wherein a transverse circular plate is arranged at the upper part of the bottom plate; acircular ring sleeves the outer circumference of the circular plate and is movably connected to the outer circumference of the circular plate through a bearing; a plurality of uniformly-distributed induction heating devices are arranged at the bottom part of the circular plate; the lower ends of the induction heating devices are pointed to a part where a central axis of the circular plate is connected to the top surface of the bottom plate; vertical rods are fixedly mounted at the upper ends of the induction heating devices, and the side parts of the vertical rods are connected to the side part of the circular ring by hinging. According to the device, an induction heating fuse wire and laser compound based additive manufacturing method is used for performing additive manufacturing; a fusewire is molten by induction heating; a laser beam is capable of promoting the stirring in a metal melting pond; the material feeding capacity per unit of time is high in the manufacturing process, and the formed metal melting pond is large, so that the additive manufacturing efficiency is high; and meanwhile, the fuse wires manufactured through a plurality of materials can be synchronously fed, so that the additive manufacturing of an alloy material is achieved; and a novel device and a novel method are provided to realize additive manufacturing.

Description

technical field [0001] The invention belongs to the field of additive manufacturing and rapid prototyping, in particular to an additive manufacturing device and method based on induction heating fuse and laser combination. Background technique [0002] Existing methods for additive manufacturing of metal materials mainly use methods such as laser, electron beam heating, and arc heating to heat metal materials to complete rapid prototyping and additive manufacturing of parts. The existing selective laser sintering additive manufacturing method uses a laser to scan on the powder, melt the powder, accumulate and repeat the sintering molding layer by layer after solidification. In the manufacturing process, the amount of material melting per unit time is small, the powder needs to be preheated, and the cost of auxiliary equipment such as powder bed is high. Using synchronous powder feeding method for laser sintering molding also has the disadvantages of less material melting pe...
