Laser selective melting (SLM) is a method for directly forming metal parts, and is the latest development of additive manufacturing technology. The technology is based on the most basic idea of rapid forming, namely an incremental manufacturing mode of cladding layer by layer, and parts with specific geometric shapes are directly formed according to a three-dimensional CAD model, and metal powder is completely melted in the forming process to generate metallurgical bonding. The metal part with complex shape and structure which cannot be manufactured by adopting the traditional machining means is one of the main directions of the application of the laser rapid prototyping technology.
In the equipment adopting the prior art, after the part is printed, the vertical driving mechanism in the forming cylinder slowly jacks up the part into the forming chamber, the forming platform is gradually jacked up, meanwhile, operators clean redundant powder on the part, and finally the part is taken out from the forming chamber door, however, the opening of the forming chamber door is smaller, the powder cleaning operation space is smaller, and particularly when the forming size is larger and the powder is more, the powder cleaning is very inconvenient, and the time and the labor are wasted.
Disclosure of Invention
The invention aims to provide a powder discharging device of a forming cylinder for additive manufacturing equipment, which solves the problem that the powder cleaning is time-consuming and labor-consuming after the forming of the existing parts.
The invention adopts the technical scheme that the molding cylinder powder discharging device for the additive manufacturing equipment comprises a molding cylinder side plate, wherein two sliding rails which are parallel to each other are arranged on one side surface of the molding cylinder side plate, a powder discharging movable plate which is vertically arranged is embedded between the two sliding rails, a powder discharging opening A and a stepped hole are respectively arranged on the powder discharging movable plate, the center of the powder discharging opening A and the center of the stepped hole are positioned on the same horizontal line, a powder discharging opening B is arranged on the molding cylinder side plate corresponding to the stepped hole, and a plug penetrates through the stepped hole and is clamped in the powder discharging opening B.
The present invention is also characterized in that,
wherein the plug comprises a blocking block, and one end of the blocking block is provided with a handle.
Wherein the blocking block is clamped in the powder discharging opening B, and the blocking block is adapted to the structure of the powder discharging opening B.
Wherein the blocking block is round, square or elliptic, and the diameter of the blocking block is smaller than the diameter of the large-caliber end of the stepped hole and larger than the diameter of the small-caliber end of the stepped hole.
Wherein the length of the handle is greater than the depth of the stepped bore.
The device has the beneficial effects that the device comprises the movable plate embedded in the sliding rail, and the powder discharging operation is carried out through the back and forth movement of the movable plate and the matching of the plug, so that the powder cleaning efficiency is greatly improved, and the workload of operators is reduced; since the most of the powder is finally discharged from the powder discharge opening A through the pipeline, the pollution of the powder is reduced; in addition, as the amount of powder manually participated in cleaning is reduced, the potential safety hazard of operators is reduced.
