Construction bin system for large metal 3D printing equipment

Abstract

The invention discloses a construction bin system for large metal 3D printing equipment. The construction bin system comprises a positioning mechanism. The positioning mechanism comprises an initial positioning assembly, a first positioning mechanism, a second positioning mechanism and a controller. The initial positioning assembly is arranged between a corresponding working station and a construction bin and is used for detecting whether the construction bin reaches the corresponding working station or not. The first positioning mechanism is arranged between the corresponding working station and a driving cylinder. The second positioning mechanism is arranged between the corresponding working station and a forming cylinder. The first positioning mechanism is used for positioning the construction bin at the lower part of the construction bin, and the second positioning mechanism is used for positioning the construction bin at the upper part of the construction bin The controller is used for controlling the construction bin to stop moving when the initial positioning assembly detects that the construction bin reaches the corresponding working station, controlling the first positioning mechanism to act and controlling the second positioning mechanism to act after the first positioning mechanism completes positioning of the construction bin. According to the construction bin system for the large metal 3D printing equipment, accurate positioning of the construction bin in the moving process can be achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a building chamber system for large-scale metal 3D printing equipment. Background technique [0002] In the 3D printing equipment using selective melting technology, the equipment mainly includes the upper printing chamber and the lower construction chamber. The printing work is carried out in the airtight construction chamber. After the printing is completed, the workpiece needs to be taken out from the construction chamber and processed. Powder cleaning, which requires downtime for processing. [0003] In recent years, with the maturity of 3D printing technology, the size of printed workpieces has become larger and larger. R&D personnel in the industry have set their sights on metal 3D printing of large workpieces. Since the removal of the workpiece and the powder cleaning need to be shut down, the utilization rate of the equipment and the printing ef...

Problems solved by technology

However, in order to achieve a good printing work, it is also necessary to consider the precise positioning of the building chamber during the moving process. Due to the split connection between the forming cylinder and the driving cylinder, and the large size of the building chamber for large workpieces, during the moving process Due to shaking and other factors, the position of the upper forming cylinder may be slightly shifted relative to the driving cylinder, which may lead to inaccurate alignment between the upper forming cylinder and the printing chamber even though the positioning of the building chamber is completed at the specified position. , it is impossible to fully guarantee that the forming cylinder and the driving cylinder are exactly the same in the fixed point position
