Embodiment 1

[0041] As a specific embodiment of the present invention, as a specific embodiment, the low-temperature supersonic spraying of the present invention produces a large number of free-form parts by manufacturing a helmet on a mold as a specific embodiment of the present invention:

[0042] Step 1: The process of spraying a low melting point release layer:

[0043] The mold is made of hard material, which is generally selected as metal, ceramic or composite material. In this embodiment, the material of the helmet die is die steel H11. Before spraying the low-melting point release layer, the powder storage tank of the low-temperature supersonic spray gun is filled with low-melting point materials, and the low-melting point materials are generally selected as metal or composite materials. In this embodiment, the low melting point material is a low melting point alloy containing tin (Sn). Then, spray a layer of low melting point material on the mold as a release layer. In this emb...

Abstract

The invention provides a method for producing a free forming part based on low-temperature supersonic spraying and application. The method comprises the following steps: (1) spraying a demolding layer: spraying the demolding layer on a supporting surface by using a low-temperature supersonic spraying device; (2) planning a path: planning a spraying path; (3) manufacturing a part: spraying a material on the supporting surface layer by layer by using a low-temperature supersonic spraying method and an edge compensation spraying process to form the part; and (4) demolding: putting the part and the supporting surface into a heating device, melting the demolding layer, and separating the part from the supporting surface, thereby obtaining the product. Through the method, the mold can be repeatedly used, and the production cost of parts is reduced.

Description

technical field [0001] The invention relates to the technical field of supersonic spraying, in particular to a method and application for producing free-form parts based on low-temperature supersonic spraying. Background technique [0002] Compared with additive manufacturing technologies such as high-speed oxygen-fuel thermal spraying and direct metal laser sintering, low-temperature supersonic spraying technology is a low-temperature process, and its working temperature is lower than the melting point of the sprayed material. Low-temperature supersonic spraying technology is more suitable for manufacturing larger parts, because this technology has high molding efficiency, low working temperature, and no phase change during spraying, which greatly reduces the porosity of parts, reduces material oxidation, and eliminates crystallization in parts problem of unevenness. However, when using this technology, the distribution and velocity of the material particles at the nozzle ...
