Three-dimensional object manufacturing equipment and its forming cylinder assembly method

Abstract

Disclosed are a manufacturing equipment for a three dimensional object and an assembling method for a forming cylinder thereof. The equipment comprises a cavity, the forming cylinder, lifting mechanisms and a controlling system. Supporting mechanisms are arranged in the position, located below the forming cylinder, on the cavity. The lifting mechanisms are arranged on the supporting mechanisms, and lifting rods of the lifting mechanisms penetrate through the supporting mechanisms and are connected with the bottom of the forming cylinder. Guide rails are mounted on the supporting mechanisms, and sliding pieces matched with the guide rails are arranged at the bottom of the forming cylinder. When the controlling system receives the instruction of forming cylinder mounting, the forming cylinder is placed on the guide rails, and the forming cylinder is pushed into the cavity till the forming cylinder reaches the first extreme position and then stops. The lifting rod of the lifting mechanisms are controlled to rise, and meanwhile, the forming cylinder is driven to conduct rising movement till the forming cylinder rises to the second extreme position and then stops, so that mounting of the forming cylinder is finished. According to the manufacturing equipment for the three dimensional object and the assembling method for the forming cylinder thereof, it is convenient to rapidly take out and mount the forming cylinder, and the working efficiency of the equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a three-dimensional object manufacturing equipment and a forming cylinder assembly method thereof. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing, referred to as AM) is an advanced manufacturing technology with distinctive features such as digital manufacturing, high flexibility and adaptability, direct CAD model drive, fast speed, and rich and diverse material types. The degree of limitation does not require any tooling and molds, so the application range is very wide. Selective Laser Melting (SLM) is one of the additive manufacturing technologies that has developed rapidly in recent years. It uses powder materials as raw materials and uses lasers to scan the cross-section of a three-dimensional entity layer by layer to complete prototype manufacturing. The complexity of the shape is limited, no tooling and mol...

Problems solved by technology

[0003] In the prior art, the molding cylinder is generally fixedly installed on the base plate inside the equipment. Since the cylinder body cannot be separated from the equipment, after the workpiece is manufactured, it is necessary to manually clean the powder and take out the package inside the equipment. However, the space of the equipment cavity is limited, so there is no It is convenient for manual operation, and because the equipment can only take out the package during non-manufacturing time, and it takes a certain amount of time to take the package, so the work efficiency of the equipment is greatly reduced
