Embodiment Construction

[0014] The process of using the present invention to manufacture workpieces will be described in detail below in conjunction with the accompanying drawings.

[0015] The specific implementation steps of the method of the present invention are as follows.

[0016] Add enough granular (powder) thermoplastic material (2) into the hopper (1) before work starts.

[0017] Set the heating temperature and heating efficiency of the primary induction heating coil (7) and the secondary induction heating coil (10) according to the properties of the granular (powder) thermoplastic material (2) and the properties of the molten material (8) to be obtained , to obtain the required molten material (8).

[0018] During work, the motor (17) is controlled to rotate, and the worm and gear device is used to drive the pulley (4) to rotate. The granular (powder) thermoplastic material (2) is deposited on the friction feeding belt (3) under the action of its own weight, and the friction feeding belt...

Abstract

The invention discloses a melt extrusion molding device suitable for multiple metal materials, and belongs to the technical field of additive manufacturing. The melt extrusion molding device is characterized in that the melt extrusion molding device comprises feeding systems, power systems, melting systems and a melt extrusion control system; each feeding system comprises a hopper, a friction feeding belt, belt wheels, a defective material recycling box and a feed barrel; the melt extrusion control system is composed of electromagnets, springs, push rods, nozzles and a flow guide block; each melting system is composed of a first-stage induction heating coil, a crucible, a second-stage induction heating coil and a screw and is mounted on the melt extrusion control system in a threaded connection manner.; and each power system is located over the corresponding melting system and is composed of a control motor, a transmission shaft, a worm wheel and a worm. According to the melt extrusion molding device, the salivation phenomenon in the melt extrusion molding process is eliminated, and the molding precision is improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a melt extrusion molding device suitable for various metal materials. Background technique [0002] 3D printing technology is a technology that uses CAD design data to manufacture solid parts by layer-by-layer accumulation of materials. Compared with traditional cutting technology, it is a bottom-up material accumulation manufacturing method. It is often used in prototype or model making in mold making, industrial design and other fields. Direct printing of parts has become an important method in the field of rapid manufacturing, and direct 3D printing technology of metal parts is one of the most important development directions. [0003] The existing mature metal 3D printing technologies mainly include selective laser sintering (Selective Laser Sintering, SLS), selective laser melting (Selective Laser Melting, SLM), laser near-net shaping (Laser Engineering Net S...
