Description

Technical Field

[0001] The present invention relates to the technical field of 3D metal printing, and in particular to a platform stabilizing device for 3D metal printing. Background Art

[0002] 3D metal printing is an advanced manufacturing technology, also known as metal additive manufacturing, which creates complex metal parts and components by stacking metal materials layer by layer. It uses high-energy lasers or electron beams to melt metal powders and print out metal parts with any complex structure and close to 100% density layer by layer.

[0003] 3D metal printing uses a laser beam to scan the powdered molding material in layers. The powder irradiated by the laser beam is melted. When a layer is scanned and melted, the workbench drops one layer of thickness, and the powder roller spreads a layer of uniform and dense powder on it until the entire shape is completed. However, 3D metal printing has high requirements on the consistency of metal powder particles. When the metal powder particles are of different sizes, the metal powder will affect the quality of the melted molded parts. The current metal powder screening device generally uses vibration to screen it. When some metal powders with larger particles accumulate at the bottom of the screening device, the larger metal powder will easily cause the screening device to be blocked, and the screening device can only cause the metal powder to roll and cannot be separated from the bottom of the screening device through vibration, thereby affecting the screening of the metal powder. Summary of the invention

[0004] The object of the present invention is to provide a platform stabilization device for 3D metal printing to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The cam is provided with a plurality of movable parts, and the movable part is provided with a plurality of movable parts, and the movable part has a plurality of movable parts, and the movable part has a plurality of movable parts.

[0008] Furthermore, the hydraulic rod is located above the mounting frame, the limiting frame is symmetrically arranged with the telescopic frame as the center, the number of the positioning plates is two, and the two positioning plates are symmetrically arranged with the screening frame as the center.

[0009] Furthermore, the electric push rod is located above the telescopic frame, the bottom of the scraper is in contact with the bottom of the inner wall of the screening frame, and the number of the interlocking plates is two, and the two interlocking plates are symmetrically arranged with the scraper as the center.

[0010] Furthermore, the bottom of the extrusion frame passes through the moving frame and extends to the inside of the moving frame, the upper surface of the semicircular plate contacts the inner wall of the moving frame, and the lower surface of the semicircular plate contacts the inner wall of the clamping hole.

[0011] Furthermore, the pushing component includes an elastic rod, the top of the elastic rod is fixedly connected to the surface of the limit frame, the lower surface of the elastic rod is hinged with a tripod, the end of the tripod away from the elastic rod is hinged with a slide, the surface of the slide is fixedly connected with a round rod, the surface of the round rod is fixedly connected with a pushing plate, and the inner wall of the screening frame is fixedly connected with a stabilizing plate.

[0012] Furthermore, the inner wall of the slide is slidably connected to the surface of the stabilizing plate, the number of the round rods is two, and the two round rods are symmetrically arranged with the elastic rod as the center, the push plate is located above the scraper, and the tripod is located above the slide.

[0013] Furthermore, the vibration component includes a synchronous frame, the lower surface of the synchronous frame is fixedly connected to the surface of the screening frame, the upper surface of the synchronous frame is fixedly connected to a cylindrical rod, the end of the cylindrical rod away from the synchronous frame is fixedly connected to a groove plate, the surface of the linkage plate is fixedly connected to a rectangular plate, the bottom of the rectangular plate is fixedly connected to a return spring, the bottom of the return spring is fixedly connected to a pressure frame, and the top of the pressure frame is fixedly connected to a triangular plate.

[0014] Furthermore, the top of the synchronous frame extends to above the screening frame, the top of the pressure frame passes through the rectangular plate and extends to the outer end of the rectangular plate, and one end of the triangular plate away from the pressure frame contacts the inner wall of the groove plate.

[0015] The present invention has the following beneficial effects:

[0016] The present invention starts the motor to start operation, and the motor drives the hydraulic rod to rotate. When the hydraulic rod rotates, it pushes the screening frame to rotate to the top of the printing frame through the connection between the telescopic frame and the limit frame. At this time, the hydraulic rod is started to move downward. When the hydraulic rod moves downward, it pushes the screening frame into the interior of the printing frame through the limit frame, so that the metal powder can be directly screened into the interior of the printing frame to avoid waste. After the metal powder is poured into the interior of the screening frame, the electric push rod is started to start operation. The electric push rod pushes the moving frame to slide on the surface of the positioning plate through the limit frame. When the limit frame moves, it pushes the scraper to slide inside the screening frame through the linkage plate. When the scraper moves, it can push the metal powder to flow inside the screening frame to avoid the metal powder accumulating inside the screening frame and affecting the screening efficiency. The extrusion frame pushes the semicircular plate to contact the inner wall of the card hole through the elasticity of the spring to limit the positioning plate, so that the limit frame pushes the screening frame into the interior of the printing frame for operation. After the screened metal powder enters the interior of the printing frame, the 3D metal printing device is started to print the metal powder.

[0017] The limit frame of the present invention pushes the tripod to deform through the elastic rod when moving, and the tripod pushes the slide to slide on the surface of the stabilizing plate as the limit frame moves. The slide drives the push plate to move inside the screening frame through the round rod when moving, and the push plate pushes the metal powder to flow inside the screening frame, thereby preventing the metal powders from condensing inside the screening frame due to friction and affecting filtration.

[0018] The screening frame of the present invention pushes the cylindrical rod to move through the synchronous frame when moving. The cylindrical rod pushes the groove plate to move and squeezes the triangular plate to move. The triangular plate is subjected to pressure and the reset spring is stretched through the pressure frame, so that the triangular plate can be reset by the elasticity of the reset spring. When the groove plate moves, it contacts the triangular plate and vibrates. The vibration is transmitted to the screening frame through the synchronous frame, so that the screening frame can screen the metal powder through the vibration, thereby further improving the screening efficiency of the metal powder.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
