Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of additive manufacturing, in particular to an additive manufacturing forming cylinder driving mechanism. Background Art
[0002] Additive manufacturing technology is based on 3D CAD model data and is a method of manufacturing by adding materials layer by layer. It is based on the computer 3D design model, and uses software layered discrete and CNC forming systems to use high-energy beams to stack materials layer by layer, and finally stack and shape them to create physical products.
[0003] In order to ensure good sealing of metal powder, the forming cylinder of existing additive manufacturing equipment generally adopts a closed lifting mechanism, which is driven by a screw from the bottom of the forming platform to lift up the forming platform. Therefore, the length of the screw is at least twice the forming height. In order to control the overall height of the equipment, the height of the formable parts of the additive manufacturing equipment will be limited. If the formable height of the equipment is increased, a large amount of space under the forming platform will be occupied by the screw, which will greatly increase the height of the equipment, further greatly increase the cost of equipment assembly and maintenance, and bring many inconveniences to the use of the equipment.
[0004] Therefore, it is necessary to provide an additive manufacturing forming cylinder drive mechanism to solve the above technical problems. Utility Model Content
