Description

Technical Field

[0001] This utility model relates to the field of manufacturing mechanism technology, and in particular to an additive manufacturing mechanism. Background Technology

[0002] Friction stir deposition (FSD) is a solid-state additive manufacturing technology that uses an additive manufacturing mechanism within a FSD system to locally plastically deform metal materials, depositing layers under pressure to achieve high-density metal structures. Because the temperature of the additive manufacturing mechanism continuously rises during operation, cooling is necessary. Currently, air cooling or liquid cooling systems attached to the additive manufacturing mechanism are mainly used. However, to avoid the liquid cooling system interfering with the operation of the additive manufacturing mechanism, it needs to be kept at a certain distance from the stirring end, resulting in relatively low heat dissipation efficiency. When the additive manufacturing mechanism temperature becomes too high, it can easily cause material blockage and other problems, thus affecting production and processing. Utility Model Content

[0007] In one embodiment of the present invention, the end of the connector is provided with a boss, the mounting base is provided with a groove, the bottom of the groove is provided with a first sealing element, and the end of the boss abuts against the first sealing element.

[0008] In one embodiment of the present invention, the sidewall of the groove is provided with a step, the sidewall of the boss is provided with a locking block, and the end face of the locking block abuts against the end face of the step.

[0015] The additive manufacturing mechanism of this invention features an inlet and outlet liquid channel on a mounting base, and a receiving groove connected to the inlet and outlet liquid channels on a connector. Coolant is introduced into the inlet hole, flowing through the inlet channel into the receiving groove, thereby dissipating heat and cooling the mounting base, connector, and agitator. The coolant absorbs heat from the additive manufacturing mechanism and exits through the outlet channel to the outlet hole, continuously cooling the additive manufacturing mechanism through its flow.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 3 As shown, an additive manufacturing mechanism of this utility model includes: a mounting base 1, the side wall of which is provided with a liquid inlet 11 and a liquid outlet 13, the mounting base 1 also includes a liquid inlet channel 12 and a liquid outlet channel 14, the liquid inlet 11 is connected to the liquid inlet channel 12, and the liquid outlet 13 is connected to the liquid outlet channel 14; a connecting member 2, which is connected to one end of the mounting base 1, the connecting member 2 is provided with a receiving groove 22, and the liquid inlet channel 12 and the liquid outlet channel 14 are both connected to the receiving groove 22; and a stirring member 3, which is connected to one end of the connecting member 2.

[0026] In this embodiment, an additive manufacturing mechanism includes a mounting base 1 with an inlet channel 12 and an outlet channel 14, and a connector 2 with a receiving tank 22 communicating with the inlet channel 12 and the outlet channel 14. Coolant is introduced into the inlet port 11, and then flows through the inlet channel 12 into the receiving tank 22, thereby cooling the mounting base 1, connector 2, and agitator 3. The coolant absorbs heat from the additive manufacturing mechanism and is then output from the outlet channel 14 to the outlet port 13. The flow of coolant continuously cools the additive manufacturing mechanism. Since the receiving tank 22 is located inside the connector 2, it can dissipate heat from the interior of the connector 2, thus improving the heat dissipation efficiency of the additive manufacturing mechanism. Furthermore, the connection between the agitator 3 and the connector 2 places the receiving tank 22 close to the agitator 3, further improving the heat dissipation efficiency of the agitator 3.

[0027] Reference Figure 2 As shown, the additive manufacturing mechanism also includes a material passage 4, which passes through the mounting base 1, the connector 2 and the mixing component 3 along the axial direction of the additive manufacturing mechanism. The center line of the material passage 4 coincides with the center line of the additive manufacturing mechanism, and the material outlet 33 of the material passage 4 is located at the end of the mixing component 3 away from the connector 2.

[0028] Mounting base 1 is used to connect with external discharge equipment. The side wall of mounting base 1 is provided with a liquid inlet hole 11 and a liquid outlet hole 13. Mounting base 1 also includes a liquid inlet channel 12 and a liquid outlet channel 14, both of which are located inside mounting base 1. The liquid inlet hole 11 communicates with the liquid inlet channel 12, and the liquid outlet hole 13 communicates with the liquid outlet channel 14. Specifically, the end of the liquid inlet channel 12 communicates with the end of the liquid inlet hole 11, and the end of the liquid outlet channel 14 communicates with the end of the liquid outlet hole 13. The center lines of the liquid inlet channel 12 and the liquid outlet channel 14 are both parallel to the center line of mounting base 1. The angle between the center line of the liquid inlet hole 11 and the center line of the liquid inlet channel 12 is an obtuse angle, and the angle between the center line of the liquid outlet hole 13 and the center line of the liquid outlet channel 14 is also an obtuse angle, that is, the liquid inlet hole 11 and the liquid outlet hole 13 are both inclined. The end of the inlet channel 12 away from the inlet hole 11 is located on the end face of the mounting base 1 near the connector 2, and the end of the outlet channel 14 away from the outlet hole 13 is also located on the end face of the mounting base 1 near the connector 2. The shortest distance from the inlet end of the inlet hole 11 to the connector 2 is greater than the shortest distance from the outlet end of the outlet hole 13 to the connector 2, that is, the position of the end of the inlet hole 11 on the side wall of the mounting base 1 is higher than the position of the end of the outlet hole 13, thereby facilitating the flow of coolant.

[0029] Reference Figure 4As shown, the connector 2 is connected to one end of the mounting base 1. The connector 2 is provided with a receiving groove 22, and both the liquid inlet channel 12 and the liquid outlet channel 14 are connected to the receiving groove 22. Specifically, the receiving groove 22 is located at the end of the connector 2 close to the mounting base 1. The positions of the liquid inlet channel 12 and the liquid outlet channel 14 correspond to the receiving groove 22, and the diameters of the liquid inlet channel 12 and the liquid outlet channel 14 are less than or equal to the width of the receiving groove 22, so that the coolant can flow into the receiving groove 22 through the liquid inlet channel 12 and flow out of the receiving groove 22 through the liquid outlet channel 14. The receiving groove 22 surrounds the edge of the end of the mounting base 1, that is, the receiving groove 22 is arranged circumferentially along the material passage 4, so that the receiving groove 22 is annular and located outside the material passage 4. The receiving groove 22, the liquid inlet channel 12, and the liquid outlet channel 14 are not connected to the material passage 4, so that the coolant can dissipate heat evenly to the connector 2 and improve the heat dissipation efficiency. The end of the connector 2 fits into the end of the mounting base 1, thereby preventing coolant leakage between the connector 2 and the mounting base 1.

[0030] Reference Figures 3 to 5 As shown, the end of the connector 2 near the mounting base 1 is provided with a boss 24, and the material passage 4 passes through the boss 24. The end of the mounting base 1 near the connector 2 is provided with a groove. The bottom of the groove is provided with a first sealing element 15 along the circumference of the material passage 4. The first sealing element 15 can be regarded as a sealing ring. The first sealing element 15 is annular. The bottom of the groove is also provided with a first connecting groove. The first sealing element 15 is engaged with the first connecting groove. The end of the boss 24 abuts against the first sealing element 15, thereby sealing the connection between the connector 2 and the mounting base 1 and preventing coolant from leaking into the material passage 4. The mounting base 1 has a second sealing element 16 at the end that abuts against the connector 2. The second sealing element 16 surrounds the edge of the end plate of the mounting base 1 and can be regarded as a sealing ring. The second sealing element 16 is annular and located outside the liquid inlet channel 12 and the liquid outlet channel 14. The end face of the mounting base 1 has a second connecting groove. The second sealing element 16 is engaged with the second connecting groove, so that the liquid inlet channel 12 and the liquid outlet channel 14 are both located between the first sealing element 15 and the second sealing element 16. The end of the connector 2 abuts against the second sealing element 16, thereby sealing the connection between the connector 2 and the mounting base 1 and preventing the coolant from flowing out to the outside.

[0031] The sidewall of the groove is provided with a step 17, and the sidewall of the boss 24 is provided with a locking block 25. The end face of the locking block 25 abuts against the end face of the step 17, thereby further improving the connection accuracy between the mounting base 1 and the connector 2. Both the sidewall of the boss 24 and the sidewall of the groove are provided with threads, with the sidewall of the boss 24 having an external thread and the sidewall of the groove having an internal thread, so that the boss 24 and the groove are threadedly connected, that is, the connector 2 and the mounting base 1 are threadedly connected, which facilitates the installation and disassembly of the connector 2 and the mounting base 1, and makes the connector 2 and the mounting base 1 detachably connected, which facilitates the processing and cleaning of the receiving groove 22, the liquid inlet hole 11, the liquid outlet hole 13, the liquid inlet channel 12, and the liquid outlet channel 14. Through the setting of the step 17 and the locking block 25, after the connector 2 and the mounting base 1 are threadedly connected, the end faces of the step 17 and the locking block 25 can press against each other, thereby making the connection between the connector 2 and the mounting base 1 more stable. Preferably, the side wall of the connector 2 is provided with at least two clamping surfaces 21 arranged opposite to each other. In this embodiment, there are two clamping surfaces 21. The clamping surfaces 21 can be regarded as cutting surfaces. The clamping surfaces 21 are planes and the planes where the two clamping surfaces 21 are located are parallel. The clamping tool abuts against the clamping surfaces 21, thereby facilitating the rotation of the connector 2 and thus facilitating the installation or disassembly of the connector 2.

[0032] Reference Figure 6 The stirring component 3 has a protrusion 32 at the end away from the connecting component 2. In this embodiment, there are two protrusions 32, which are centrally symmetrically arranged. The protrusions 32 are teardrop-shaped, but depending on the manufacturing process, they can also be hemispherical. The stirring component 3 can have different numbers of protrusions 32. In this embodiment, the end of the stirring component 3 away from the connecting component 2 is flat. Depending on the manufacturing process, this end can also be convex or concave. The material outlet 33 of the material channel 4 is located at the end of the stirring component 3 away from the connecting component 2. In this embodiment, the end face of the material outlet 33 is circular. Depending on the manufacturing process, the end face of the material outlet 33 can also be elliptical or square. Preferably, the end of the stirring component 3 away from the connecting component 2 is provided with a wear-resistant and non-stick coating.

[0033] Reference Figure 3 and Figure 6 As shown, the connector 2 has a mounting groove 23 at one end for connecting the agitator 3. The side wall of the mounting groove 23 is threaded, and the side wall of the agitator 3 is also threaded. Specifically, the side wall of the mounting groove 23 has an internal thread, and the side wall of the agitator 3 has an external thread, thereby allowing the agitator 3 to be detachably connected to the connector 2, which facilitates the replacement of the agitator 3. The side wall of the agitator 3 has at least two clamping grooves 31. In this embodiment, the side wall of the agitator 3 has four centrally symmetrical clamping grooves 31. The clamping end of the clamping tool engages with the clamping grooves 31, which facilitates the rotation of the agitator 3, thus facilitating the installation or removal of the agitator 3.

[0034] During the operation of the additive manufacturing mechanism, coolant is introduced into the inlet port 11. The coolant enters the receiving tank 22 through the inlet channel 12. After absorbing the heat of the additive manufacturing mechanism, the coolant in the receiving tank 22 is output from the outlet channel 14 to the outlet port 13 until the coolant flows out to the outside. When it is necessary to replace the agitator 3, the agitator 3 is disassembled from the connector 2 by rotating it, and then the replacement agitator 3 is connected to the connector 2 by rotating it.

[0035] This invention discloses an additive manufacturing mechanism. A mounting base 1 has an inlet channel 12 and an outlet channel 14, and a connector 2 has a receiving tank 22 communicating with the inlet and outlet channels 12 and 14. Coolant is introduced into the inlet port 11, and then flows through the inlet channel 12 into the receiving tank 22, thereby cooling the mounting base 1, connector 2, and agitator 3. The coolant absorbs heat from the additive manufacturing mechanism and is then output from the outlet channel 14 to the outlet port 13. The continuous flow of coolant continuously cools the additive manufacturing mechanism. Because the receiving tank 22 is located inside the connector 2, it can dissipate heat from the interior of the connector 2, thus improving the heat dissipation efficiency of the additive manufacturing mechanism. Furthermore, the connection between the agitator 3 and the connector 2 places the receiving tank 22 close to the agitator 3, further improving the heat dissipation efficiency of the agitator 3. The detachable connection of connector 2, mounting base 1 and mixing component 3 makes it easy to replace different mounting bases 1 and mixing components 3 as needed, thus eliminating the need to manufacture multiple additive mechanisms and only requiring the manufacture of multiple mounting bases 1 and mixing components 3, thereby reducing manufacturing costs.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
