Description

Metal 3D printer with exchange shaping jar

Technical Field

The invention relates to the technical field of additive manufacturing, in particular to a metal 3D printer with an exchange forming cylinder.

Background

The 3D printing technology is that a three-dimensional model is divided into a plurality of layers in a computer, and materials such as plastics, metals and even biological tissue active cells are sintered or bonded together layer by layer on a plane according to a layered graph of the three-dimensional model through 3D printing equipment, and finally a three-dimensional object is formed.

Metal 3D printing technology, being the leading and most promising technology in the overall 3D printing system, is an important direction of development for advanced manufacturing technologies. With the demands of scientific and technological development and popularization and application, the 3D printing technology is utilized to directly manufacture metal functional parts, so that the main development direction of 3D printing is formed.

The existing metal 3D printer is used for manually performing post-processing such as powder cleaning after the whole metal part is molded, then taking out the metal part, dividing the next metal part into a plurality of layers according to a three-dimensional model in a computer, printing layer by layer until the printing is completed, and having low printing efficiency, which cannot meet the requirements of performing post-processing on the printed part while performing three-dimensional printing, so that the metal 3D printer capable of improving the printing efficiency of the part is urgently needed.

Disclosure of Invention

In order to solve the technical problem, a metal 3D printer with an exchange forming cylinder is provided, the purpose of exchanging the forming cylinder is achieved, the standby time of the 3D printer is saved, and the utilization rate of equipment is improved.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the metal 3D printer with the exchange forming cylinder comprises a forming chamber arranged on a powder bed, a vibrating mirror system arranged above the forming chamber, a filtering system communicated with the forming chamber, a plurality of powder cleaning boxes arranged on the forming chamber and exchangeable forming cylinder mechanisms arranged below the powder bed, wherein the forming cylinder mechanisms comprise a plurality of forming cylinder structures and exchange platforms used for mutual exchange of the forming cylinder structures, each forming cylinder structure comprises an exchange forming cylinder arranged below the powder bed and a sliding seat arranged at the bottom of the exchange forming cylinder, and the sliding seat is slidably arranged on the exchange platforms.

Further, clear powder case includes clear powder case in a left side and clear powder case in the right side, the shaping jar structure includes left exchange shaping jar and right exchange shaping jar, and left exchange shaping jar cunning locates under clear powder case in a left side or the shaping room, right exchange shaping jar cunning locates under shaping room or the clear powder case in the right side.

Through the technical scheme, the metal 3D printer with the exchange forming cylinder adopts the exchange forming cylinder, the left powder cleaning box and the right powder cleaning box, so that the left forming cylinder works, the right forming cylinder works and the left forming cylinder works, the standby time of the 3D printer is saved, and the utilization rate of equipment is improved.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without creative efforts.

FIG. 1 is a schematic diagram of a usage state of a metal 3D printer with an exchange molding cylinder according to an embodiment of the present invention;

fig. 2 is a schematic view of another usage state of the metal 3D printer with the exchange molding cylinder according to the embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The following describes the embodiments of the present invention in further detail with reference to the schematic drawings.

Referring to fig. 1 and 2, the metal 3D printer with the exchange molding cylinder comprises a molding chamber 2 disposed on a powder bed 1, a galvanometer system 3 disposed above the molding chamber 2, and a filtering system 4 communicated with the molding chamber 2, and further comprises two left powder cleaning boxes 5 and right powder cleaning boxes 6 disposed adjacent to the molding chamber, and an exchangeable molding cylinder mechanism disposed below the powder bed 1, wherein the molding cylinder mechanism comprises a left molding cylinder structure 7, a right molding cylinder structure 8, and an exchange platform 9 for exchanging the left molding cylinder structure 7 and the right molding cylinder structure 8, the left molding cylinder structure 7 comprises a left exchange molding cylinder 71 disposed below the powder bed 1 and a first slide carriage 72 disposed at the bottom of the exchange molding cylinder 71, the right molding cylinder structure 8 comprises a right exchange molding cylinder 81 disposed below the powder bed 1 and a second slide carriage 82 disposed at the bottom of the exchange molding cylinder 81, and the first sliding seat 72 and the second sliding seat 82 are slidably arranged on the exchange platform 8, the left exchange forming cylinder 71 is slidably arranged under the left powder cleaning box 5 or the forming chamber 2, the right exchange forming cylinder 81 is slidably arranged under the forming chamber 2 or the right powder cleaning box 6, and gloves 10 are further arranged on the left powder cleaning box 5 and the right powder cleaning box 6.
