A laser selective melting forming equipment

Abstract

The invention relates to a laser selective melting forming equipment. The equipment at least includes: a two-dimensional mobile device, a forming workbench, a forming cabin, an auxiliary cabin, a powder spreading device, a powder feeding device, a powder recovery device and a laser printer. On the other hand, the two-dimensional moving device is connected and can drive the forming worktable to move between the forming cabin and the auxiliary cabin, wherein the two-dimensional moving device includes a longitudinal drive unit for driving the forming worktable to move longitudinally, and a driving unit for driving the forming work The horizontal drive unit for the horizontal movement of the table. In the sealed state of the forming cabin, the laser printer melts the metal powder on the forming workbench into predetermined parts. The excess powder recovery device is used to recover excess metal powder. The two-dimensional moving mechanism drives the forming The workbench moves from the forming cabin to the auxiliary cabin, and the auxiliary cabin is provided with a pick-up window for removing the parts on the forming workbench.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing equipment, in particular to a laser selective melting forming equipment. Background technique [0002] At present, the domestic laser selective melting SLM equipment can process metal parts with small size and light weight. After forming, they can be taken out directly from the forming cabin. In addition, due to the small size of the formed parts and the small area of ​​the forming table, its flatness can easily meet the requirements of laser melting. , the forming height is small, the straightness of the lifting motion of the forming table and the verticality of the lifting motion and the table surface are relatively easy to guarantee. [0003] With the development of laser selective melting technology, it is necessary to explore how to use laser selective melting technology to make larger parts. The requirements for large-scale and precision equipment are getting higher and higher...

AI Technical Summary

Problems solved by technology

[0004] With the increase of the size and specifications of the machinable parts, how to take out the parts after forming, how to ensure the flatness of the forming table after the area of ​​the forming table becomes larger, and how to ensure the straightness and perpendicularity to the table surface after the lifting stroke increases to meet the requirements of laser selective melting The existing equipment main structure is difficult to meet these requirements, and new ideas and new main structure types are needed to solve these problems
