The invention discloses a multi-laser high-efficiency two-way powder spreading control system, which includes a forming chamber, a light source installed on the side wall of the forming chamber, and a camera installed on the top of the forming chamber. Multiple lasers are arranged above the forming chamber. There is a forming cylinder fixedly connected to the lower part, and a lifting platform is arranged in the forming cylinder, and a working platform is arranged on the lifting platform, and powder-feeding chambers are fixed on the left and right sides of the top of the forming chamber, and scrapers are arranged in the forming chamber, and the two sides below the forming chamber are also A powder collection barrel is provided, the camera is electrically connected to a computer, and the computer is also electrically connected to the control part of the scraper, the control part of the powder bin, the laser, and the control part of the lifting platform. The multi-laser high-efficiency two-way powder spreading control system of the present invention performs multi-laser scanning and forming while bidirectional powder spreading. The invention also discloses a control method of the above-mentioned multi-laser high-efficiency two-way powder spreading control system.
Description
technical field [0001] The invention belongs to the technical field of SLM equipment, and relates to a multi-laser high-efficiency two-way powder spreading control system, and also relates to a control method of the above-mentioned multi-laser high-efficiency two-way powder spreading control system. Background technique [0002] With the continuous development of SLM technology, the forming size of SLM equipment parts is also increasing, and multi-laser equipment emerges in an endless stream. While ensuring a larger forming size, multi-laser is also continuously reducing the forming time of single-layer equipment. The printing of large-format parts also brings new problems. The time for scraper movement to spread powder becomes longer and longer as the size of the part increases. For one-way powder spreading equipment, there is also a waste of return time. How to improve the efficiency of multi-laser printing while ensuring the forming size of parts is a problem worth study...
