Description

Technical Field

[0001] The present invention relates to the technical field of friction stir additive manufacturing equipment, and in particular to a tool system, a friction stir additive manufacturing device and a control method. Background Art

[0002] Friction Stir Additive Manufacturing (FSAM) is a new type of solid-phase additive manufacturing technology that uses the friction heat generation principle of a rotating tool head to deposit metal or alloy materials layer by layer into a complex structure through heating, plastic deformation, and metal flow. This process has significant advantages because it can avoid liquid phase forming, such as reducing material thermal cracks, improving workpiece performance, and reducing deformation. Therefore, friction stir additive manufacturing technology has received widespread attention in the manufacture of aerospace, automobiles, ships, and other high-performance structural parts.

[0003] However, in actual application, the Friction Stir Additive Manufacturing technology faces some challenges. One of them is that due to the frictional heating effect, the additive material in the rotating tool head will expand, causing its volume to increase. As the additive material expands, the extrusion force of the material when entering the rotating tool head gradually increases, thereby increasing the feeding resistance. This situation not only affects the stability of the manufacturing process, but also may lead to insufficient material supply, which in turn affects the accuracy and efficiency of the entire additive manufacturing process.

[0004] In order to alleviate this problem, some solutions in the prior art set a water-cooling jacket or cooling system on the handle of the rotating tool head, trying to reduce the impact of frictional heat generation through external cooling. Although these cooling methods can reduce the temperature of the tool head to a certain extent, thereby partially alleviating the expansion of the additive material, due to the limited cooling effect, the cooling system is difficult to effectively control the accumulation of frictional heat in the entire additive manufacturing process. As a result, in actual operation, the temperature of the rotating tool head is difficult to stabilize, and there are still problems such as increased feeding resistance, poor material fluidity, and unstable workpiece quality.

[0032] The tool system 100 of the friction stir additive manufacturing device according to the embodiments of the present invention will be described below with reference to the drawings.

[0033] Refer to Figure 1According to an embodiment of the present invention, a tool system 100 of a friction stir additive manufacturing device includes a tool handle 10, a rotating tool head 20 and a water receiving part 30.

[0034] The rotating tool head 20 is disposed on the tool handle 10, and the rotating tool head 20 is provided with a discharge port 21 for discharging the additive material. The water receiving member 30 is provided with a water inlet 31. The rotating tool head 20 is provided with a first flow channel 22, and the first flow channel 22 is connected to the water inlet 31 to control the temperature of the rotating tool head 20.

[0035] The rotary tool head 20 is mounted on the tool handle 10, and the tool handle 10 drives the rotary tool head 20 to rotate. The rotary tool head 20 is provided with a discharge port 21, and the discharge port 21 discharges the additive material, and the additive material is deposited layer by layer. The water inlet 31 on the water receiving part 30 is used for the inflow of the cooling medium, and the water inlet 31 is connected to the first flow channel 22 on the rotary tool head 20. The cooling medium flows into the first flow channel 22 from the water inlet 31, and the cooling medium flows in the rotary tool head 20. The cooling medium directly contacts the rotary tool head 20 and directly affects the temperature of the rotary tool head 20.

[0036] Friction Stir Additive Manufacturing (FSAM) is a new type of solid-phase additive manufacturing technology that uses the friction heat generation principle of a rotating tool head to deposit metal or alloy materials layer by layer into a complex structure through heating, plastic deformation, and metal flow. This process has significant advantages because it can avoid liquid phase forming, such as reducing material thermal cracks, improving workpiece performance, and reducing deformation. Therefore, friction stir additive manufacturing technology has received widespread attention in the manufacture of aerospace, automobiles, ships, and other high-performance structural parts.

[0037] However, in actual application, the Friction Stir Additive Manufacturing technology faces some challenges. One of them is that due to the frictional heating effect, the additive material in the rotating tool head will expand, causing its volume to increase. As the additive material expands, the extrusion force of the material when entering the rotating tool head gradually increases, thereby increasing the feeding resistance. This situation not only affects the stability of the manufacturing process, but also may lead to insufficient material supply, which in turn affects the accuracy and efficiency of the entire additive manufacturing process.

[0038] To alleviate this problem, in the prior art, some solutions set a water-cooling jacket or a cooling system on the tool shank of the rotating tool head, attempting to reduce the influence of heat generated by friction through external cooling. Although these cooling means can, to a certain extent, reduce the temperature of the tool head, thereby partially alleviating the expansion phenomenon of the additive material, due to the limited cooling effect, it is difficult for the cooling system to effectively control the accumulation of heat generated by friction during the entire additive manufacturing process. This results in the temperature of the rotating tool head being difficult to stabilize during actual operation, and there are still problems such as increased feeding resistance, poor material fluidity, and unstable workpiece quality.

[0039] In the embodiment of the present invention, by opening a first flow channel 22 on the rotating tool head 20, the first flow channel 22 communicates with the water inlet 31, and the cooling medium enters the first flow channel 22 from the water inlet 31. The cooling medium flows within the rotating tool head 20 to directly control the temperature of the rotating tool head 20. The first flow channel 22 is directly arranged on the rotating tool head 20, improving the cooling effect. During actual operation, the temperature of the rotating tool head 20 can be controlled relatively quickly, thereby improving problems such as large feeding resistance, poor material fluidity, and unstable workpiece quality.

[0040] Specifically, the tool shank 10 drives the rotating tool head 20 to rotate, and the cooling medium flows into the first flow channel 22 on the rotating tool head 20 from the water inlet 31 on the water receiving member 30. The cooling medium reduces the temperature of the rotating tool head 20, preventing the additive material from expanding and blocking within the rotating tool head 20.

[0041] Specifically, the cooling medium can be cooling water or cooling oil.

[0042] According to the tool system 100 of the embodiment of the present invention, by arranging the first flow channel 22 on the rotating tool head 20 and the cooling medium flowing within the first flow channel 22, the cooling medium directly contacts the rotating tool head 20, improving the cooling effect. During actual operation, the temperature of the rotating tool head 20 can be controlled relatively quickly, thereby improving problems such as large feeding resistance, poor material fluidity, and unstable workpiece quality.

[0043] Refer to Figure 1 In some embodiments, at least part of the first flow channel 22 extends along the direction from the tool shank 10 to the discharge port 21.

[0044] Among them, in the direction from the tool shank 10 to the discharge port 21, at least part of the first flow channel 22 extends. The first flow channel 22 at least partly extends from the tool shank 10 towards the discharge port 21. The first flow channel 22 extends in the direction towards the discharge port 21, and the first flow channel 22 is close to the discharge port 21.

[0045] In the above solution, by arranging at least part of the first flow channel 22 to extend in the direction from the tool handle 10 to the discharge port 21, the first flow channel 22 is close to the discharge port 21, and the cooling medium in the first flow channel 22 can better affect the temperature of the entity around the discharge port 21, thereby increasing the influence range and further improving the temperature control effect.

[0046] Specifically, part of the first flow channel 22 extends in the direction from the tool handle 10 to the discharge port 21; or, the first flow channel 22 extends entirely in the direction from the tool handle 10 to the discharge port 21.

[0047] Refer to Figure 2 , in some embodiments, the first flow channel 22 includes: a first sub - portion 221, a second sub - portion 222, and a third sub - portion 223.

[0048] The first sub - portion 221 extends in the direction from the tool handle 10 to the discharge port 21. One end of the second sub - portion 222 is connected to the first sub - portion 221, and the second sub - portion 222 is configured to be inclined relative to the first sub - portion 221. The third sub - portion 223 is connected to the other end of the second sub - portion 222, and the third sub - portion 223 extends in the direction from the tool handle 10 to the discharge port 21.

[0049] Wherein, the first sub - portion 221 is connected to the second sub - portion 222, and the second sub - portion 222 is connected to the third sub - portion 223. The cooling medium flows in the first sub - portion 221, the second sub - portion 222, and the third sub - portion 223. The cooling medium contacts the rotary tool head 20 to cool the rotary tool head 20, and there is a certain included angle between the second sub - portion 222 and the first sub - portion 221. The second sub - portion 222 and the first sub - portion 221 affect the rotary tool head 20 in different orientations.

[0050] In the above solution, by arranging the connected first sub - portion 221, second sub - portion 222, and third sub - portion 223, the cooling medium flows in the first sub - portion 221, the second sub - portion 222, and the third sub - portion 223. The second sub - portion 222 is arranged to be inclined relative to the first sub - portion 221. The first sub - portion 221 affects the rotary tool head 20 in the first orientation, and the second sub - portion 222 affects the rotary tool head 20 in the second orientation, increasing the influence range and further improving the temperature control effect on the rotary tool head 20.

[0051] Specifically, the first sub - portion 221 extends in the vertical direction, the second sub - portion 222 extends in the horizontal direction, and the first sub - portion 221 is perpendicular to the second sub - portion 222, increasing the influence range and improving the temperature control effect.

[0052] Refer to Figure 1 、 Figure 2 , in some embodiments, the tool handle 10 is rotatably arranged in the water receiving member 30, and a second flow channel 11 is provided on the tool handle 10. One end of the second flow channel 11 is connected to the water inlet 31, and the other end is connected to the first flow channel 22.

[0053] Among them, the tool handle 10 is rotatably arranged in the water receiving member 30. The tool handle 10 rotates while the water receiving member 30 remains stationary, which facilitates the water inlet 31 to communicate with the water supply device. The water inlet 31 communicates with the first flow channel 22 through the second flow channel 11. The cooling medium passes through the water inlet 31 and the second flow channel 11 to the first flow channel 22 in sequence.

[0054] In the above solution, by arranging the second flow channel 11 on the tool handle 10, one end of the second flow channel 11 communicates with the water inlet 31 and the other end communicates with the first flow channel 22. The cooling medium first flows to the tool handle 10 and then flows into the rotary tool head 20. The cooling medium cools the tool handle 10, increasing the influence range of the cooling medium, thereby controlling the temperature of more parts of the tool system 100 and expanding the influence range.

[0055] Specifically, a first sealing member 33, such as a gland packing, is provided between the water receiving member 30 and the tool handle 10 to achieve rotary sealing while the tool handle 10 rotates.

[0056] Refer to Figure 1 、 Figure 2 , in some embodiments, the tool handle 10 is provided with a groove 12. The groove 12 extends along the circumferential direction of the tool handle 10, and the groove 12 is arranged inside the water receiving member 30. The space inside the groove 12 communicates with the water inlet 31 and the first flow channel 22.

[0057] Among them, the groove 12 is annularly arranged on the surface of the tool handle 10. A space is formed on the surface of the tool handle 10 for the flow of the cooling medium. The space inside the groove 12 communicates with the water inlet 31 and the first flow channel 22. The cooling medium enters the groove 12 from the water inlet 31 and flows inside the groove 12.

[0058] In the above solution, by arranging the groove 12 on the tool handle 10, the flow space of the cooling medium is increased by using the groove 12, so that the cooling medium contacts a larger area of the tool handle 10, thereby further improving the cooling effect and making the temperature control effect stronger.

[0059] Specifically, the groove 12 is formed on the surface of the tool handle 10. The groove 12 is located inside the water receiving member 30, and the water receiving member 30 blocks the opening of the groove 12, so that the cooling medium is always inside the groove 12.

[0060] Refer to Figure 1 、 Figure 2 , in some embodiments, the opening of the second flow channel 11 is arranged on the side wall of the groove 12.

[0061] Among them, the opening of the groove 12 faces the water receiving member 30, the opening of the second flow channel 11 is arranged on the side wall of the groove 12, and the cooling medium inside the groove 12 directly flows to the second flow channel 11.

[0062] In the above solution, by arranging the opening of the second flow channel 11 on the side wall of the groove 12, the cooling medium in the groove 12 automatically flows into the second flow channel 11 without the need for external power drive, thus making the overall structure simpler and simplifying the overall structure.

[0063] Referring to Figure 2 , in some embodiments, the water receiving member 30 is further provided with a water outlet 32, the water outlet 32 communicates with the second flow channel 11, and the water outlet 32 and the water inlet 31 are arranged on opposite sides of the tool handle 10.

[0064] Among them, the cooling medium is discharged from the water outlet 32 to the outside of the tool system 100. That is to say, the cooling medium enters the tool system 100 from the water inlet 31 and then is discharged from the water outlet 32 to the outside of the tool system 100.

[0065] In the above solution, by arranging the water outlet 32 on the water receiving member 30, the cooling medium is discharged from the water outlet 32, and the water inlet 31 and the water outlet 32 are arranged on opposite sides of the tool handle 10, so that the water inlet 31 and the water outlet 32 do not interfere with each other, increasing the flow path of the cooling medium in the tool system 100, thereby increasing the influence range and further improving the cooling effect.

[0066] In some embodiments, the tool handle 10 is provided with a groove 12, the groove 12 extends along the circumferential direction of the tool handle 10, and the groove 12 is arranged inside the water receiving member 30. The space in the groove 12 communicates with the water inlet 31, the first flow channel 22, and the water outlet 32; the part of the groove 12 facing the water inlet 31 and the part of the groove 12 facing the water outlet 32 are not communicated in the circumferential (circumferential) direction.

[0067] In some embodiments, the tool handle 10 and the rotary tool head 20 are of an integral structure.

[0068] Referring to Figure 2 , in some embodiments, the tool system 100 of the friction stir additive manufacturing device further includes: a temperature sensing member 40 and a control member.

[0069] The temperature sensing member 40 is arranged on the rotary tool head 20. The control member is electrically connected to the temperature sensing member 40, the water inlet 31 is communicated with a water supply device, the water supply device is provided with a water temperature adjusting member, and the control member is electrically connected to the water temperature adjusting member.

[0070] Among them, the temperature sensing member 40 arranged on the rotary tool head 20 is used to detect temperature changes and transmit them to the control member, and the control member adjusts the temperature change of the cooling medium according to the temperature change.

[0071] In the above solution, by arranging the temperature sensing member 40 on the rotary tool head 20, the temperature sensing member 40 cooperates with the control member to control the temperature of the cooling medium, optimize the performance of the tool system 100, and fully adapt to different requirements.

[0072] Specifically, the temperature sensor 40 provided on the rotary tool head 20 is used to detect temperature changes in real time and wirelessly transmit the temperature to the control component through the temperature wireless transmitter 41. The control component adjusts the temperature of the cooling medium according to the temperature change. When the temperature decreases, the temperature of the cooling medium is increased to avoid problems such as poor workpiece forming caused by excessive cooling. When the temperature is high, the temperature of the cooling medium is decreased to ensure the cooling effect.

[0073] Referring to Figure 2 , in some embodiments, the tool shank 10 is mounted on the first flange 13. A second flange 14 is provided on the tool shank 10. The rotary tool head 20 is connected to the second flange 14. A second seal 23 is provided between the rotary tool head 20 and the tool shank 10. The second seal 23 has a flow channel / through hole for the cooling medium to flow through.

[0074] The friction stir additive manufacturing device according to an embodiment of the present invention includes the above-mentioned tool system 100.

[0075] According to the friction stir additive manufacturing device of the embodiment of the present invention, by providing the first flow channel 22 on the rotary tool head 20, the cooling medium flows in the first flow channel 22, so that the cooling medium directly contacts the rotary tool head 20, improving the cooling effect. In actual operation, the temperature of the rotary tool head 20 can be controlled more quickly, thereby improving problems such as large feeding resistance, poor material fluidity, and unstable workpiece quality.

[0076] Referring to Figure 3 , Figure 4 , according to the control method of the tool system of the embodiment of the present invention, the tool system includes: a tool shank, a rotary tool head, and a water receiving member. A temperature sensor is provided on the rotary tool head. The water receiving member is communicated with a water supply device provided with a water temperature adjusting member; wherein, the control method includes:

[0077] S2: Obtain a working signal.

[0078] S3: Obtain the temperature data transmitted by the temperature sensor.

[0079] S4: Control the water temperature adjusting member according to the temperature data and the set temperature.

[0080] Specifically, the temperature sensor 40 measures the temperature in real time. The temperature sensor 40 is connected to a temperature wireless transmitter 41, and the temperature wireless transmitter 41 transmits the temperature data. By comparing the temperature change fluctuation range, when the temperature fluctuation becomes larger (i.e., the real-time temperature is higher than the preset target range temperature), the temperature of the cooling medium is decreased. When the temperature fluctuation becomes smaller (i.e., the real-time temperature is lower than the preset target range temperature), the temperature of the cooling medium is increased.

[0081] According to the control method of the tool system according to an embodiment of the present invention, by providing a first flow channel on the rotating tool head, the cooling medium flows in the first flow channel, so that the cooling medium directly contacts the rotating tool head, improving the cooling effect. In actual operation, the temperature of the rotating tool head can be controlled more quickly, thereby improving problems such as large feeding resistance, poor material fluidity, and unstable workpiece quality.
