Description
Technical Field
[0001] This utility model belongs to the field of additive manufacturing technology, specifically relating to a 3D printing device with expandable workstations. Background Technology
[0002] On a large powder bed 3D printing machine, the forming cylinder first performs powder sintering at the forming station, then moves to the powder cleaning station for powder cleaning. After the powder cleaning is completed, the cylinder is moved to the part removal station for workpiece lifting.
[0003] In the above process, the large powder bed 3D printing equipment mainly consists of a forming station, a forming cylinder, a powder cleaning station, a part removal station, and a cylinder transfer guide rail. However, most of the time only the forming station is used, while the part removal station and the powder cleaning station are used for a relatively short time. The excessive idle time results in wasted equipment space, and the equipment occupies too much area, resulting in low factory utilization. Furthermore, when multiple machines are operated, the excessive distance makes operation inconvenient. Too many auxiliary devices increase the complexity of operation and the probability of failure.

The frame of this invention is equipped with at least two forming workstations, one powder cleaning workstation, and one part picking workstation. A powder cleaning workstation and a part picking workstation are provided between two adjacent forming workstations, so that two adjacent forming workstations share one powder cleaning workstation and one part picking workstation. This reduces the number of auxiliary equipment originally provided, lowers equipment costs, reduces equipment footprint, reduces operational complexity, and improves equipment stability.
[0005] To achieve the above objectives, this utility model provides an expandable 3D printing equipment, including a frame, a cylinder transfer guide rail, and a forming cylinder; the frame is equipped with at least two forming stations, one powder cleaning station, and one part removal station; a powder cleaning station and a part removal station are provided between two adjacent forming stations;
[0006] The cylinder transfer guide rail is fixedly installed on the frame; each forming station is assigned a forming cylinder, which is movably installed on the cylinder transfer guide rail. The forming cylinder can move back and forth along the cylinder transfer guide rail and can move to the forming station, the part removal station and the powder cleaning station.
[0007] Furthermore, the frame includes frame one and frame two, and the cylinder transfer guide rail includes guide rail one and guide rail two;

[0031] Example 1
[0032] See Figure 1 As shown, this embodiment provides an expandable 3D printing device, including a frame 8, a cylinder transfer rail 4, a left forming cylinder 2, and a right forming cylinder 7. The frame 8 is equipped with a left forming station 1, a right forming station 6, a powder cleaning station 5, and a part removal station 3. The powder cleaning station 5 and the part removal station 3 are located between the left forming station 1 and the right forming station 6. The cylinder transfer rail 4 is fixedly installed on the frame 8. The left forming cylinder 2 and the right forming cylinder 7 are movably installed on the cylinder transfer rail 4 and can move back and forth along the cylinder transfer rail 4.
[0033] After the left forming cylinder 2 completes sintering at the left forming station 1, it moves to the powder cleaning station 5 for powder cleaning. After the powder cleaning is completed, the left forming cylinder 2 moves to the part removal station 3 for part removal. Similarly, after the right forming cylinder 7 completes sintering at the right forming station 6, it moves to the powder cleaning station 5 for powder cleaning. After the powder cleaning is completed, the right forming cylinder 7 moves to the part removal station 3 for part removal.
[0034] This embodiment integrates two forming stations into one machine, sharing a powder cleaning station 5 and a part picking station 3, which greatly reduces the size of the machine, lowers the cost of the machine, and improves the utilization rate of the factory. Moreover, it can print two workpieces at the same time in a limited space, thus improving work efficiency.
[0035] Example 2
[0036] like Figure 2 As shown, this embodiment provides an expandable 3D printing device, including a frame 8, a cylinder transfer guide rail 4, a left forming cylinder 2, and a right forming cylinder 7. The frame 8 includes a first frame 80 and a second frame 81, and the cylinder transfer guide rail 4 includes a first guide rail 40 and a second guide rail 41. The first guide rail 40 is fixedly installed on the first frame 80, and a left forming station 1 is installed on the first frame 80, forming an independent module. The second guide rail 41 is fixedly installed on the second frame 81, and a right forming station 6, a powder cleaning station 5, and a part removal station 3 are installed on the second frame 81, forming an expansion module. There are two expansion modules. The independent module is connected in series with one of the expansion modules, wherein the first frame 80 and the second frame 81 are spliced together. The two expansion modules are connected in series, wherein two second frames 81 are spliced together.
[0037] In this embodiment, the left powder cleaning station 5 and the left part picking station 3 are located between the left forming station 1 and the middle right forming station 6; the right powder cleaning station 5 and the right part picking station 3 are located between the middle right forming station 6 and the right right forming station 6.
[0038] The left forming cylinder 2 and the two right forming cylinders 7 are movably mounted on the cylinder body transfer guide rail 4 and can move back and forth along the cylinder body transfer guide rail 4, that is, they can move back and forth along guide rail 1 40 and guide rail 2 41.
[0039] After sintering at the left forming station 1, the left forming cylinder 2 moves to the left cleaning station 5 for cleaning. After cleaning, the left forming cylinder 2 moves to the left picking station 3 for picking up parts. Similarly, after sintering at the right forming station 6, the right forming cylinder 7 moves to the right cleaning station 5 for cleaning. After cleaning, the right forming cylinder 7 moves to the right picking station 3 for picking up parts. The right forming cylinder 7, located in the middle, can clean at the left cleaning station 5 and pick up parts at the left picking station 3, or it can clean at the right cleaning station 5 and pick up parts at the right picking station 3, without having to wait because the cleaning station 5 and picking station 3 are occupied, thus increasing the equipment utilization rate.
