Abstract

The invention discloses a high-temperature-resistant fused deposition manufacturing printing device which comprises a five-axis linkage mechanism, a printing device body, a machining unit, a temperature control unit, a temperature sensor and a connection control system. The printing device main body comprises a sealing cylinder and a sealing ring arranged at the upper edge of the sealing cylinder, the sealing cylinder and the sealing ring are hollow, and the sealing cylinder and the sealing ring communicate with each other; the processing unit comprises a printing table arranged in the sealing cylinder and a printing head arranged on the upper portion of the sealing cylinder, and the printing table and the printing head are oppositely arranged. The printing head and the printing table realize movement during processing through a five-axis linkage mechanism; the temperature control unit comprises a gas pipeline and an airflow nozzle; the gas pipeline is communicated with the sealing cylinder to input hot airflow; a plurality of airflow nozzles are arranged on the sealing cylinder and the sealing ring; the control system regulates and controls the angle and the flow of the airflow spray head according to temperature information collected by the temperature sensor, the local temperature and the overall temperature are controlled, it is guaranteed that the overall temperature of a printed piece changes synchronously, and the machining quality and stability are improved.

Description

technical field [0001] The invention belongs to the field of fused deposition type additive manufacturing, and in particular relates to a high temperature resistant fused deposition manufacturing printing device, which can change the temperature of the molding environment. Background technique [0002] Since the 21st century, 3D printing technology has entered a moment of vigorous development, which is regarded as a major revolution in intelligent manufacturing, which has promoted the rapid development of emerging industries and profound changes in the industry. Compared with traditional manufacturing and forming methods, 3D printing technology has the advantages of low operation difficulty, few forming steps, and high production efficiency, and its development is particularly rapid. Compared with other 3D printing technology paths, FDM has the advantages of low cost and simple structure, so it has been popularized and valued. [0003] However, FDM (Fused Deposition Modelin...
