Molten metal 3D printing device based on electric arc heat source

Abstract

The invention discloses a molten metal 3D printing device based on the electric arc heat source. The device comprises a body, a box body is attached to the bottom of the body, the outer wall of a double-thread screw is in clearance fit with the inner wall of the box body, and first threaded sleeves are arranged at the two ends of the outer wall of the double-thread screw correspondingly; and the inner walls of the two first threaded sleeves are in threaded connection with the two ends of the outer wall of the double-thread screw correspondingly, the outer walls of the two first threaded sleeves are in clearance fit with the inner wall of the box body, and the tops of two pulleys are attached to the two ends of the bottom of the body correspondingly. According to the molten metal 3D printing device based on the electric arc heat source, a motor is connected with an external power source, so that the motor can drive the double-thread screw to rotate, and when the double-thread screw rotates and two first threaded sleeves synchronously move, corresponding rod bodies and first sliding blocks are driven to synchronously move and stably ascend and descend; and when the body drives the pulleys to rotate through two first sliding groove rods, the stability of lifting motion is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a molten metal 3D printing device based on an arc heat source. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files and uses bondable materials such as powdered metal or plastic to construct by layer-by-layer printing. object technology. [0003] Although the existing molten metal 3D printing device can use bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing, when the existing molten metal 3D printing device works, the molten metal 3D The height of the printing device is fixed, and it is inconvenient for workers of different heights to operate the molten metal 3D printing device. Contents of the invention [0004] The object of the present invention is to provide a molten metal 3D printing device based on an arc he...
