Low-melting-point metal melting extrusion device and use method thereof

Abstract

The invention discloses a low-melting-point metal melting extrusion device and a use method thereof. The low-melting-point metal melting extrusion device comprises an extrusion device body, gripper mechanisms and heating blocks; spray heads, spray head shell supporting frames, a circuit adaptor, a switching fixing plate, a material conveying mechanism, spray head heating mechanisms, a first heating block, a feeding pipe, a spiral heating pipe, a third heating block are arranged on the extrusion device body; the material conveying mechanism is composed of a feeding gear, a stepping motor conveyor belt and a multifunctional clamping hand mechanism; and the power source input end of the stepping motor conveyor belt is connected with the power source output end of the circuit adaptor, the power output end of a stepping motor is connected with the first end of the feeding gear, and two gripper synergistically feed materials to the heating blocks. According to the low-melting-point metal melting extrusion device and the use method thereof, the particular design of a feeding mechanism and inner structures of the spray heads is adopted, the phenomena of fractures of wires and blocking of the spray heads being prone to occurring in the process of printing forming of traditional spray heads are avoided, and the effects of rapid forming and printing are improved.

Description

technical field [0001] The invention relates to the technical field of low-melting-point metal melting extrusion devices, in particular to a low-melting-point metal melting extrusion device and a method for using the same. Background technique [0002] Now there are printers on the market with dual-nozzle metal printing, because the metal wire used is too soft and the density is not equal, the phenomenon of wire feeding interruption or empty wire feeding often occurs. If the corresponding wire pipe is used to feed the wire, it may increase the cost. In this way, the equipment will become very large, and it is not suitable for preventing the uneven thickness of the silk from affecting the blockage of the pipeline. [0003] When using a dual-nozzle 3D printer to print, the two nozzles work alternately, that is, one works and the other will pause, and then replace the other after working for a while. However, the nozzle that pauses printing will have flow. When it starts prin...

AI Technical Summary

Problems solved by technology

However, the nozzle that pauses printing will have flow. When it starts printing again, because the nozzle has flow, it will wipe the flow from the mouth to the side of the model during printing, so that the two nozzles alternately. problem, the result seriously affects the printing effect
