A build chamber system for large metal 3D printing equipment

Abstract

The present application discloses a building bin system for large-scale metal 3D printing equipment, including a positioning mechanism. The positioning mechanism includes: an initial positioning component is set between the corresponding working station and the building bin, and the initial positioning component is used to detect the building bin. Whether it has reached the corresponding working station; the first positioning mechanism is set between the corresponding working station and the drive cylinder, and the second positioning mechanism is set between the corresponding working station and the forming cylinder; the first positioning mechanism is used to construct The lower part of the warehouse positions the construction warehouse, and the second positioning mechanism is used to position the construction warehouse on the upper part of the construction warehouse; the controller is used to control the construction warehouse to stop moving when the initial positioning component detects that the construction warehouse reaches the corresponding working station, And control the action of the first positioning mechanism, and control the action of the second positioning mechanism after the first positioning mechanism finishes positioning the construction bin. The construction chamber system for large-scale metal 3D printing equipment of the present application can realize the precise positioning of the construction chamber during the moving process.

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
