Problems solved by technology

[0003] The existing metal 3D printing technology, which is widely used and has relatively mature technology, is often in the form of a single material, and the additive manufacturing of multi-metal composite materials has not yet been realized.
Single-material metal printers have the advantages of easy implementation of numerical control systems and simple structural design; however, the simplicity of this technology also greatly limits its own product manufacturing capabilities, making it prohibitive in front of many multi-metal composite product projects

Embodiment Construction

[0015] Such as Figure 5 As shown, the present invention includes 4 metal nozzles (1), a nozzle platform (2), 4 nozzle clamping parts (3) and 4 pairs of customized plate springs, which are installed together to form a nozzle group as shown in the figure. Among them, the nozzle located in the upper right corner has been pressed down to enter the working state, which belongs to the working nozzle, while the other three nozzles are clamped by the clamping parts and are in the suspended state. The overall printing process is as follows: First, computer modeling is carried out. After the modeling is completed, the computer analyzes the model data as numerical control data and transmits it to the numerical control system. Control the print head group designed emphatically in the present invention to move in the X and Y axis directions, so as to complete the printing process step by step.

[0016] In the printing process of products with 4 kinds of metal raw materials, the specific ...

Abstract

The invention discloses an automatic wire changing device for an electric-arc fuse metal printer. The automatic wire changing device comprises four metal spray heads, a spray head platform, four sprayhead clamping parts and four pairs of customized plate springs, which co-define a spray head group as shown in the Fig. each spray head is connected to a metal raw material, and is controlled by a numerical-control system I to move. The spray head supporting platform has the function of driving each spray head to realize numerical-control rotation; the automatic wire changing device is mutually matched with the clamping parts and the customized plate springs, so that a conversion function between a working state and a hanging state of each metal spray head is realized; the two functions are mutually matched, so that the automatic wire changing function of the device is realized. Therefore, the device can accomplish an additive manufacturing process of a multi-metal composite material, andhas great product customizing potential.

Description

technical field [0001] The invention belongs to the technical field of metal additive manufacturing, and in particular relates to a design scheme of an automatic wire changing device for an arc fuse metal printer. Background technique [0002] The arc fuse additive manufacturing technology uses the arc as a heat source to melt the welding wire, and the material is piled up and formed layer by layer under the control of the numerical control system, and finally the product parts are formed. This technology is mostly based on cold metal transition welding technology (CMT technology), and its main technical process is as follows: the generation and extinguishment of the arc is controlled by a digital welding control system to realize pulsed welding wire delivery; after the droplet drips from the welding wire, The numerical control system increases the welding current again to further send the welding wire forward; after that, the welding arc is regenerated again for a new round...
