Problems solved by technology

[0005] At present, metal rapid prototyping includes laser cladding molding, plasma arc cladding molding, and metal gas shielded welding surfacing molding. The cost is higher and the cladding efficiency is lower
During the plasma arc cladding molding process, the arc temperature is high, and the heat concentrated cladding molding effect is good, but the equipment cost is high, and it is difficult to process the parts of the cantilever structure

Embodiment Construction

[0032] see Figure 1 to Figure 3 , a method of surfacing metal parts supported by metal powder based on the present embodiment, which includes the following steps:

[0033] (1) According to the shape and structure of the metal parts to be formed, use 3D drawing software to create a 3D part model of the corresponding shape and structure, and convert the 3D part model into an STL format image file. The 3D drawing software can be UG, Pro-E, etc.

[0034] (2) Carry out hierarchical processing to the STL format map file, obtain layered overlay welding forming path trajectory data, and import the layered overlay welding forming path trajectory data into the control system of the metal overlay welding forming machine; see figure 2 Specifically, layering is carried out by the host computer software, including the following steps: (2.1) read all the triangle patch data of the STL format image file through the host computer software, and then select the direction to be layered, the di...

Abstract

The invention discloses a method for surfacing welding forming of a metal part on the basis of metal powder support. The method includes the following steps that (1) modeling is carried out through three-dimensional mapping software, and a mode is converted into an STL format; (2) layered processing is conducted; (3) metal forming materials are prepared; (4) metal powder support materials are prepared; (5) a metal surfacing welding forming machine is started for surfacing welding according to a layered surfacing welding forming path track; (6) after one layer is stacked, the fourth step and the fifth step are repeated until surfacing welding of a whole part is completed, and the metal part is obtained. The method is simple in procedure, low in cost and easy to achieve; surfacing welding forming can be conducted on metal parts of different shapes rapidly, forming efficiency is high, and the effect is good; the metal parts which are good in mechanical property, high in compactness, intensity and hardness and good in rigidity can be manufactured, the rapid forming speed of the metal parts can also be greatly increased, the whole forming cycle is shortened, and the method can be widely applied and popularized conveniently.

Description

technical field [0001] The invention relates to the technical field of surfacing welding and forming, in particular to a method for forming metal parts by surfacing welding based on metal powder support. Background technique [0002] There are many manufacturing methods for metal parts. From different technological perspectives, the traditional technological methods mainly include cutting, casting and forging stamping. The utilization rate of raw materials in the cutting process is low, and the processing cost of parts with complex shapes is high. The defect problem of parts in the casting process is very serious, and the defective rate is high. In the process of forging and stamping, the cost of processing molds for parts with complex shapes is relatively high, and it is difficult to process molds. [0003] Rapid prototyping (RP) technology is an advanced manufacturing technology developed in the 1990s. It is a key common technology for the development of new products for...
