Description

Technical Field

[0001] The present invention relates to the technical field of metal 3D printers, and in particular to a metal 3D printer with an atomization device. Background Art

[0002] A 3D printer, also known as a three-dimensional printer (3DP), is a machine that uses cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metals or plastics and other adhesive materials to print layers of adhesive materials to create three-dimensional objects.

[0003] Traditional metal printers output materials through pipes, resulting in a smaller dispersion range when the materials are sprayed out. When printing large-area objects, a long period of reciprocating motion of the machine is required, and the printing efficiency is low. Some equipment with atomization devices have fixed atomization nozzle tracks, and therefore, in actual use, the atomization range of the metal consumables cannot be adjusted. The height of the printer nozzle needs to be adjusted to make the spray range of the consumables larger, but this is difficult to control and can easily cause uneven spraying.

[0004] Metal printers consume metal consumables during use. Such metal consumables require a small particle size, are difficult to produce, and are expensive. In actual use, the consumables usually cannot fully meet the requirements, and the discharge pipe will often be blocked. The selected materials are of inferior quality, uneven in thickness, easy to solidify into blocks, and incompletely melted, making it very troublesome to clean the pipe. Summary of the invention

[0025] like Figure 1As shown, the power assembly 6 includes a fixed ring 601 and a driving motor 602, wherein the fixed ring 601 is fixed around the upper side wall of the rotating block 5, the driving motor 602 is fixedly connected to the side wall of the sliding plate 3, and the output shaft of the driving motor 602 is connected to a power gear 603, which meshes with the gear on the fixed ring 601. The driving motor 602 is started to drive the power gear 603 connected to the output shaft of the driving motor 602 to rotate, and the rotation of the power gear 603 drives the rotation of the fixed ring 601 meshed with it, thereby driving the rotation of the rotating block 5 fixed around the fixed ring 601, and then the rotating block 5 can drive the fixed pipe 12 inside it to rotate, so that the fixed pipe 12 can rotate around the discharge nozzle 4 when the inert gas is ejected, so that the gas flow direction around the bottom of the discharge nozzle 4 is more uniform, ensuring that the metal particles can be evenly dispersed during ejection without deflecting to one side.

[0026] like Figure 2 , Figure 3 , Figure 4 As shown, the cleaning assembly 8 includes a rotating tube 801, the inner wall of which is slidably connected to a center rod 803, the center rod 803 and the outer wall of the bottom end of the rotating tube 801 are both surrounded by crushing pieces 804, the top of the center rod 803 is rotatably connected to a telescopic rod 805 fixed to the side wall of the sliding plate 3, the rotating tube 801 is rotatably connected to the inner wall of the discharging nozzle 4 through a bearing, and the output shaft of the power motor 9 is rotatably connected to the connecting gear ring 802 mounted on the lower end of the center rod 803 through a driving gear 901.

[0027] like Figure 3 , Figure 6As shown, the adjustment assembly 13 includes a rotating bearing 131 and a pull rod 133. The bottom of the rotating bearing 131 is rotatably connected with a plurality of electric lifting rods 132. The electric lifting rods 132 are fixed to the inner wall of the rotating block 5. Both ends of the pull rod 133 are rotatably connected to the rotating bearing 131 and the side wall of the fixed tube 12 through a rotating shaft 134. The electric lifting rod 132 drives the rotating bearing 131 to reciprocate up and down, and then the rotating bearing 131 drives the fixed tube 12 to rotate through the pull rod 133, so that the outlet at the bottom of the fixed tube 12 is deflected, thereby changing the ejection direction of the gas.

The rotating block 5 is made of metal, and the rotation of the rotating block 5 drives the rotation of the fixed tube 12.

[0030] Working principle: When the equipment is in use, through the action of the feed pipes 7 on both sides of the top of the discharge nozzle 4, the feed pipes 7 are connected to the material, so that the metal particles can enter the inside of the discharge nozzle 4, and in the process of the metal particles flowing, the larger particles will gradually be pushed to the top of the discharge nozzle 4, and the power motor 9 is started, and the connecting gear ring 802 is driven to rotate through the driving gear 901, and the rotating tube 801 and the internal center rod 803 are driven to rotate through the connecting gear ring 802, and then the crushing piece 804 at the bottom of the rotating tube 801 and the internal center rod 803 is driven to rotate, which can break the larger particles on the top of the discharge nozzle 4, and can effectively reduce the probability of metal particles clogging the inside of the discharge nozzle 4.

The air guide pipe 15 is connected to the inert gas, and the air guide pipe 15 is connected to the connecting pipe 11 through the air guide ring 10, and the connecting pipe 11 is connected to the fixed pipe 12, so that the fixed pipe 12 can spray inert gas. When the metal particles are sprayed, the rotating block 5 is driven to rotate through the power component 6, and then the rotating block 5 can drive the fixed pipe 12 inside it to rotate, and the fixed pipe 12 can rotate around the discharge nozzle 4 when spraying the inert gas, so that the gas flow direction around the bottom of the discharge nozzle 4 is more uniform, ensuring that the metal particles can be evenly dispersed during spraying without deflecting to one side. The entire printing process is carried out in a housing 1 filled with inert gas protection to prevent the metal powder from reacting with active gas at high temperature or even exploding, thereby ensuring the safety of the processing process. When it is necessary to adjust the atomization and dispersion range of the metal particles, the electric lifting rod 132 drives the rotating bearing 131 to reciprocate up and down, and then the rotating bearing 131 drives the fixed tube 12 to rotate through the pull rod 133, so that the outlet at the bottom of the fixed tube 12 is deflected, and then the gas ejection direction can be changed, so that the angle between the gas flow direction and the discharge nozzle 4 changes, so that the atomization range of the metal particles when ejected can be adjusted as needed, and the operation is simple. A production panel is provided at the bottom of the inner wall of the housing 1, and the hot melt material in the discharge nozzle 4 is squeezed out from the discharge nozzle 4 and then deposited on the production panel. After the previous layer of material is solidified, the material is continued to be squeezed from the discharge nozzle 4 onto the solidified material of the previous layer, and a solid is manufactured by printing layer by layer. Regarding the connection method between the production panel and the discharge head 4, the production panel and the discharge head 4 can be set to move in three dimensions relative to each other according to the existing technology. Now the technology is very mature and will not be described here.
