Problems solved by technology
[0003] Based on the process characteristics of selective laser melting layer-by-layer processing mentioned above, the weight of the working platform will gradually increase during the process of forming parts. For large-area forming work platforms, when forming large-height parts, only relying on the existing ball screw transmission mechanism cannot bear the weight change of the work platform in a wide range

The invention discloses a selective laser melting multifunctional forming working table. The selective laser melting multifunctional forming working table comprises a working platform and a vertical motion control system used for driving the working platform to vertically move and do hydraulic balance; the working platform comprises a movable base table, a heating base plate and a forming base plate which are sequentially arranged from bottom to top; the vertical motion control system comprises a synchronous driving device and a hydraulic balance control device; the synchronous driving device comprises two sub-driving mechanisms which are arranged on the two sides of the mobile base table and can be capable of synchronously working to drive the mobile base table to vertically move; the hydraulic balance control device comprises a balance oil cylinder and an energy accumulator which communicates with oil liquid in the balance oil cylinder and can compress gas in the energy accumulator; and according to the working table, the precision control over the vertical motion of the working platform is improved, bearing of a vertical driving mechanism is reduced, and the working table not only can be suitable for forming of small-height parts, but also can be suitable for the field of large-area forming, and when high parts are formed, large-range weight changes of the working platform can be borne.
Description
technical field [0001] The invention relates to the field of selective laser melting, in particular to a selective laser melting multifunctional forming workbench. Background technique [0002] Selective laser melting, also known as SLM, is a technology that uses metal powder to be completely melted under the heat of a laser beam, then cooled and solidified to form a shape. Under the action of high laser energy density, the metal powder is completely melted, and after heat dissipation and cooling, it is metallurgically welded with solid metal. It is through this process that selective laser melting forms a three-dimensional entity layer by layer. According to the layered slicing information of the 3D CAD model of the molded part, the scanning system controls the laser beam to act on the powder in the area to be formed. After one layer of scanning is completed, the working platform will drop a distance after one layer and then the powder feeding system will deliver a certain ...
