Description

Technical Field

[0044] Embodiment 2:

[0045] like Figure 2As shown, an embodiment of the present invention provides an additive manufacturing device for a gas turbine compressor blade, which is further expanded according to the content of the specific embodiment 1:

[0046] The powder extraction mechanism 6 includes a horizontal rotating motor 601, which is installed in the main body 1 of the additive manufacturing equipment and below the operating table 2. The bottom of the printing plate telescopic rod 506 is installed on the horizontal rotating motor 601. A powder extraction port 602 is opened at the bottom of the printing chamber 202.

At the same time, the horizontal rotating motor 601 is started, so that the horizontal rotating motor 601 drives the printing plate telescopic rod 506 to rotate, so that the printed part on the printing base 505 rotates, and the powder residue is further reduced. After cleaning the metal powder, the printing base 505 is raised to the highest point by the lifting motor 501, and the printed part is taken out.

[0049] Embodiment three:

[0050] like Figure 6 As shown, an embodiment of the present invention provides an additive manufacturing device for a gas turbine compressor blade, which is further expanded according to the content of the specific embodiment 1:

[0051] Among them, the high-temperature sensing module 8 is evenly distributed around the printing chamber 202. The high-temperature sensing module 8 includes a temperature sensor 801 and a signal transmitter 802. The lifting motor 501, the horizontal rotating motor 601, the fan 605 and the partition plate motor 701 are all provided with a signal receiver 803 and an actuator 804. The temperature sensor 801, the signal transmitter 802, the signal receiver 803 and the actuator 804 are electrically connected in sequence. If during the printing process, the laser melts the metal powder, the metal powder accumulates, resulting in internal heat accumulation and temperature rise. When the temperature sensed by the temperature sensor 801 reaches a certain height, the lifting motor 501, the horizontal rotating motor 601, the fan 605 and the partition plate motor 701 are activated through the signal transmitter 802 and the signal receiver 803, so that the printing base plate 505 drops rapidly, and the accumulated heat metal powder is extracted into the recovery bag 604 to prevent the metal powder from continuing to heat up.

[0052] Working principle: When printing the gas turbine compressor blades, the required metal powder is placed in the powder bin 201. At this time, the powder bin bottom plate 502 in the powder bin 201 is located at the bottom of the powder bin 201, and the printing base plate 505 in the printing bin 202 is located at the top of the printing bin 202. The motor gear disc 509 is driven to rotate by the lifting motor 501. Under the meshing action of the motor gear disc 509 and the threaded teeth 508 on the powder bin lifting sleeve rods 504 and the printing bin lifting sleeve rods 507 on both sides, the powder bin lifting sleeve rods 504 and the printing bin lifting sleeve rods 507 are driven to rotate. Through the sleeve connection structure of the powder bin lifting sleeve rod 504 and the powder bin telescopic rod 503, and the sleeve connection structure of the printing bin lifting sleeve rod 507 and the printing plate telescopic rod 506, The powder bin lifting sleeve rod 504 rises in the vertical direction, driving the powder bin bottom plate 502 to rise, causing the print bin lifting sleeve rod 507 to descend in the vertical direction, driving the print base plate 505 to descend. After the powder bin bottom plate 502 rises, the metal powder in the powder bin 201 is pushed out of the powder bin 201, and the push plate motor 301 drives the push plate screw 302 to rotate. Under the meshing action of the push plate screw 302 and the screw groove 303, the powder feeding push plate 3 moves from the side of the powder bin 201 away from the print bin 202 to the top of the collection box 203, pushing the metal powder overflowing from the powder bin 201 to the print bin 202, and evenly spreading the metal powder on the print base plate 505. If there is excess metal powder, the powder feeding push plate 3 pushes this part of the metal powder to the collection box 203. At this time, the push plate motor 301 drives the powder feeding push plate 3 to move in the opposite direction, return to the initial position, and flatten the metal powder in the printing chamber 202 again, and laser melt the metal powder in the printing chamber 202 through the laser module 4, and repeat the above operation to print the gas turbine compressor blades; when printing is completed, the printing base plate 505 is lowered so that the powder and the printed part reach the height of the powder extraction port 602, and the partition plate motor 701 drives the transmission gear plate 702 to rotate, so that the partition plate 704 slides in the partition plate movable groove 703, so that the powder extraction port 602 is connected with the powder extraction pipeline 603, and the powder is extracted into the recovery bag 604 through the fan 605, and the horizontal rotation motor 601 is started at the same time. The rotating motor 601 drives the printing plate telescopic rod 506 to rotate, so that the print on the printing base plate 505 rotates, further reducing the powder residue. After cleaning the metal powder, the printing base plate 505 is raised to the highest point through the lifting motor 501 to take out the print; if during the printing process, the laser melts the metal powder, the metal powder accumulates, causing internal heat accumulation and temperature increase, when the temperature sensor 801 senses that the temperature reaches a certain height, the lifting motor 501, the horizontal rotating motor 601, the fan 605 and the partition plate motor 701 are activated through the signal transmitter 802 and the signal receiver 803, so that the printing base plate 505 is quickly lowered, and the accumulated heat metal powder is extracted into the recovery bag 604 to prevent the metal powder from continuing to heat up.
