Description

Technical field [0001] The invention relates to the field of parts processing and manufacturing, in particular to a part manufacturing equipment and method combining laser cutting and electromagnetic welding. Background technique [0002] In recent years, with the increasing market demand for product customization services, the rapid production of small batches of customized parts at a lower cost has become the future development trend of the industry. The introduction of 3D printing technology has made the process of producing customized parts more convenient. Therefore, 3D printing technology has developed rapidly in both research and industrial manufacturing fields. At present, in the field of 3D printing technology, the principle of laser melting metal powder raw materials is mainly used for production. However, due to the forming principle of metal direct sintering technology and the equipment and technical methods used, this technology still has the following limitations: ...

AI Technical Summary

Problems solved by technology

[0003] 1. The manufacturing process of parts is to sinter a single layer on the powder bed first, and then lay a new layer of powder to continue sintering. Therefore, when the protruding part of the sintering structure is sintered, the bottom must have a supporting structure. This process is prolonged increased processing time, and consumed materials

[0004] 2. The sintered structure of each layer needs to be continuous, or have a lower support structure to ensure that the position of the target part does not shift during processing, thus increasing the complexity of the post-processing process

[0005] 3. The target part will also be limited by the space of the powder bed

The working space of traditional equipment is generally small, so only small parts can be manufactured

[0006] 4. Only a single material can be used. If composite materials are used, the materials inside the powder bin will be mixed. Not only will the materials in the part structure be doped, but it will also cause pollution of the powder bin materials.

[0011] 3. Due to the fast heating speed and rapid temperature change of this technology during 3D printing, it is easy to cause stress concentration in the cladding layer, and the cracking tendency is large, and cracks are easy to occur

In addition, the price of such technical equipment and metal powder materials is relatively high, and the operation is complicated, which often requires a large amount of initial investment by the production enterprise, which raises the threshold for the use of technology
