Description

Technical Field

[0001] The present invention relates to the technical field of wax mold bonding, and more specifically, the present invention relates to an automatic bonding machine for wax mold cluster trees of turbines and a bonding method thereof. Background Art

[0002] Wax mold cluster tree bonding refers to the process of bonding multiple single wax molds (i.e., wax parts) together in a specific order and position during precision casting to form an integral structure, which is usually referred to as a "wax mold cluster tree" or "cluster tree". This technology is mainly used in investment casting or lost-wax casting and is widely applied in the production of various precision parts.

[0003] When assembling a cluster tree for turbine wax molds, a heating tool (such as an electric soldering iron) is usually used to heat the turbine wax mold and the runner wax mold, melting the wax at the bonding site between the turbine wax mold and the runner wax mold, so as to bond multiple turbine wax molds to the runner wax mold. However, after heating the wax mold, wax liquid will adhere to the surface of the heating tool. During use, the wax liquid will gradually accumulate. Due to the heat insulation effect of the wax liquid, the accumulation of the wax liquid will cause the heating tool to require a higher temperature and a longer time to melt the wax mold, affecting heat conduction, resulting in uneven temperature at the bonding site of the wax mold, thus affecting the accuracy and efficiency of the wax mold cluster tree. Moreover, it takes a certain amount of time for the wax liquid to solidify when bonding the wax molds. When it is necessary to flip the bonding surface, flipping too early will cause unstable bonding, and flipping too late will reduce efficiency, thus affecting work efficiency.

[0004] The present invention provides an automatic bonding machine for wax mold cluster trees of turbines and a bonding method thereof, aiming to solve the problems that the accumulation of wax liquid affects heat conduction, resulting in uneven temperature at the bonding site of the wax mold, thus affecting the accuracy and efficiency of the wax mold cluster tree, and that it takes a certain amount of time for the wax liquid to solidify when bonding the wax molds, affecting the flipping time of the bonding surface and work efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0040] Refer to Figure 1 and Figure 3, the material transfer mechanism 3 includes a first lead screw module 31 installed at the top of one side of the first support frame 1 close to the second support frame 2. A second lead screw module 32 perpendicular to the first lead screw module 31 is installed on the first lead screw module 31. A material transfer plate 33 is installed on the second lead screw module 32. A plurality of suction nozzles 34 for adsorbing wax molds are evenly installed on the material transfer plate 33. The plurality of suction nozzles 34 are all connected to an external negative pressure device. The first lead screw module 31 is used to drive the second lead screw module 32 to move left and right. The second lead screw module 32 is used to drive the material transfer plate 33 and the suction nozzles 34 to move up and down. The number of the suction nozzles 34 and the air outlet holes 86 is the same and their positions correspond to each other. A pressing plate 35 is fixedly connected to the bottom of the material transfer plate 33. When the material transfer plate 33 drives the wax mold to move downward and contact the top of the heating plate 47, the pressing plate 35 can push the heating plate 47 and the limiting block 46 to move downward inside the limiting chute 45.

[0041] Reference Figure 4 - Figure 7 , the heating mechanism 4 includes a guide rail 41. A support cross beam 11 is fixedly connected to the inner side of the first support frame 1. The guide rail 41 is fixedly connected to the top of the support cross beam 11. A slider 42 is slidably connected to the top of the guide rail 41. An installation block 43 is fixedly connected to the top of the slider 42. A moving cylinder 44 for driving the installation block 43 to move is installed on the top of the support cross beam 11. A limiting chute 45 is opened on the top of the installation block 43. A limiting block 46 is slidably connected inside the limiting chute 45. A heating plate 47 is fixedly connected to one side of the limiting block 46 close to the second support frame 2. A first elastic member 48 is connected between the bottom of the limiting block 46 and the bottom of the limiting chute 45.

[0042] Reference Figure 1 and Figure 9 , the clamping and rotating mechanism 5 includes a transmission device 51. The transmission device 51 can be a speed reducer. The transmission device 51 is fixedly connected to one side of the second support frame 2 close to the first support frame 1. An inner support chuck 52 for clamping the runner wax mold is installed on one side of the transmission device 51 close to the first support frame 1. A motor 53 for driving the transmission device 51 to rotate is installed on the transmission device 51. A support block 54 is fixedly connected to one side of the support cross beam 11 close to the second support frame 2. A rotating groove 55 for placing the runner wax mold is opened at the top of one side of the support block 54 close to the second support frame 2.

[0043] Reference Figure 1 and Figure 2 , the feeding mechanism 6 includes a conveyor 61. A plurality of material placing trays 62 are evenly installed on the conveying chain of the conveyor 61. A plurality of material placing grooves 63 for placing wax molds are evenly opened on each material placing tray 62. The number of the material placing grooves 63 and the suction nozzles 34 is the same and their positions correspond to each other.

[0044] During actual use, the runner wax pattern is clamped and fixed by the clamping and rotating mechanism 5. First, one end of the runner wax pattern is sleeved on the outer peripheral side of the inner support chuck 52, and the other end of the runner wax pattern is placed in the rotating groove 55. Then, controlling the inner support chuck 52 to open can clamp and fix the runner wax pattern.

[0045] After the clamping and fixing is completed, the turbine wax pattern on the feeding mechanism 6 is moved above the runner wax pattern by the material moving mechanism 3. First, control the first lead screw module 31 to drive the second lead screw module 32 to move above the feeding mechanism 6. Control the second lead screw module 32 to drive the moving plate 33 and the suction nozzles 34 to move downward, so that the plurality of suction nozzles 34 contact the corresponding turbine wax patterns. The external negative pressure device is used to make the plurality of suction nozzles 34 generate negative pressure to adsorb the turbine wax patterns. After the adsorption is completed, control the second lead screw module 32 to drive the turbine wax pattern adsorbed by the suction nozzles 34 to move upward. Then, control the first lead screw module 31 to drive the second lead screw module 32 to move above the runner wax pattern to complete the material transfer.

[0046] After the material transfer is completed, control the heating mechanism 4 and the material moving mechanism 3 to heat the turbine wax pattern and the runner wax pattern. First, control the cylinder 44 to extend to push the mounting block 43 and the slider 42 to slide above the guide rail 41, thereby driving the heating plate 47 to move between the plurality of turbine wax patterns and the runner wax pattern. Then, control the second lead screw module 32 to drive the moving plate 33 and the turbine wax pattern adsorbed by the suction nozzles 34 to move downward, so that the bonding parts of the plurality of turbine wax patterns contact the top of the heating plate 47. When the moving plate 33 moves downward, it will synchronously drive the pressing plate 35 to move downward, thereby pushing the heating plate 47 and the limit block 46 to move downward inside the limit sliding groove 45 through the pressing plate 35, so that the bottom of the heating plate 47 contacts the runner wax pattern, and thus the wax pattern can be heated by the heat generated by the heating plate 47.

[0047] After the heating is completed, control the second lead screw module 32 to drive the turbine wax pattern adsorbed by the suction nozzles 34 to move upward. Then, control the cylinder 44 to retract to pull the heating plate 47 back to the initial position. Then, control the second lead screw module 32 to drive the turbine wax pattern adsorbed by the suction nozzles 34 to move downward to contact the runner wax pattern, thereby completing the bonding of the wax patterns. After the bonding is completed, control the external negative pressure device to release the adsorption of the turbine wax pattern by the suction nozzles 34. Then, control the material moving mechanism 3 to move away from above the runner wax pattern to perform the material transfer work again. Then, control the motor 53 to rotate, thereby driving the runner wax pattern to rotate through the transmission device 51 and the inner support chuck 52, so as to flip the bonding surface of the runner wax pattern to facilitate the bonding of the next group of turbine wax patterns.

[0048] Embodiment 2

[0049] In the actual working process, the heating tool used to heat the wax mold will have wax liquid adhering to its surface after heating the wax mold. During use, the wax liquid will gradually accumulate. Due to the heat insulation effect of the wax liquid, the accumulation of the wax liquid will cause the heating tool to require a higher temperature and a longer time to melt the wax mold, affecting heat conduction, resulting in uneven temperature at the bonding part of the wax mold, and thus affecting the accuracy and efficiency of wax mold tree assembly. Therefore, in this embodiment, the device described in the above embodiment is improved.

[0050] Reference Figure 2 - Figure 10 It further includes a scraping mechanism 7. The scraping mechanism 7 is arranged on the heating mechanism 4 and is used to cooperate with the movement of the heating mechanism 4 during operation to scrape off the accumulated wax liquid on the heating mechanism 4. The scraping mechanism 7 includes a scraping plate 71. The scraping plate 71 is slidably sleeved on the outside of the heating plate 47. A second elastic member 72 is connected between one end of the scraping plate 71 close to the limit block 46 and the limit block 46. The second elastic member 72 is sleeved on the outside of the heating plate 47. A through-shaped communication hole 74 is formed in one side of the limit block 46. A rotating groove 75 communicated with the communication hole 74 and corresponding in position is formed inside the limit block 46. A threaded rod 73 is fixedly connected to the inner side of the first support frame 1. The threaded rod 73 is slidably connected in the communication hole 74. A threaded sleeve 76 capable of cooperating with the threaded rod 73 is rotatably connected inside the rotating groove 75. A pulling rope 77 is wound around the outside of the threaded sleeve 76. The pulling rope 77 can be a steel wire rope. One end of the pulling rope 77 is fixedly connected to the threaded sleeve 76, and one end of the pulling rope 77 passes through the limit sliding groove 45 and is fixedly connected to the scraping plate 71.

[0051] During actual use, since the threaded rod 73 is fixedly connected to the inner side of the first support frame 1, during the process of the air cylinder 44 extending to push the mounting block 43 and the slider 42 to slide above the guide rail 41, the threaded sleeve 76 can cooperate with the threaded rod 73, causing the threaded sleeve 76 to rotate forward. During the forward rotation of the threaded sleeve 76, the pulling rope 77 will be wound up, causing the scraping plate 71 to move towards the limit block 46 on the outside of the heating plate 47 and compressing the second elastic member 72.

[0052] When the heating plate 47 finishes heating the wax mold, when the air cylinder 44 retracts to pull the mounting block 43 and the slider 42 to slide above the guide rail 41, the threaded sleeve 76 cooperates with the threaded rod 73, causing the threaded sleeve 76 to rotate in reverse. During the reverse rotation of the threaded sleeve 76, the pulling rope 77 will be unwound. At this time, the scraping plate 71 will gradually move away from the limit block 46 on the outside of the heating plate 47 under the elastic return action of the second elastic member 72. During the movement of the scraping plate 71, the wax liquid adhering to the outside of the heating plate 47 will be scraped off, thereby preventing the accumulation of wax liquid.

[0053] In summary, through the setting of the scraping mechanism 7, after the heating plate 47 completes the heating of the wax mold, during the process of the mounting block 43 returning to the initial position, the threaded sleeve 76 can cooperate with the threaded rod 73, causing the threaded sleeve 76 to reverse. During the reverse rotation of the threaded sleeve 76, the drawstring 77 will be unwound, and the scraping plate 71 will gradually move away from the limiting block 46 on the outside of the heating plate 47 under the elastic rebound of the second elastic member 72, and scrape off the wax liquid adhering to the outside of the heating plate 47, thereby preventing the accumulation of wax liquid. On the one hand, it enables the heating plate 47 to better conduct heat, ensuring uniform temperature at the bonding location, thereby improving the bonding quality and the connection strength between the wax molds. On the other hand, it can keep the surface of the heating plate 47 clean, enabling rapid heating every time it contacts the wax mold, reducing the time wasted on cleaning the heating plate 47, and improving work efficiency.

[0054] Embodiment Three

[0055] During the actual working process, it takes a certain amount of time for the wax liquid to solidify when the wax mold is bonded. When it is necessary to flip the bonding surface, flipping too early will result in unstable bonding, and flipping too late will lead to reduced efficiency, thus affecting work efficiency. Therefore, this embodiment improves the device described in the above embodiment.

[0056] Reference Figure 1 、 Figure 8 and Figure 9 Furthermore, it also includes an auxiliary cooling mechanism 8. The auxiliary cooling mechanism 8 is arranged on the clamping and rotating mechanism 5 and is used to cooperate with the material transfer mechanism 3 and the heating mechanism 4 to accelerate the cooling speed of the bonding location of the wax mold during wax mold bonding. The auxiliary cooling mechanism 8 includes a piston plate 81. A sealing groove 82 is opened inside the support block 54. The piston plate 81 is slidably connected in the sealing groove 82. A support rod 83 is fixedly connected to the top of the piston plate 81. A third elastic member 84 is connected between the bottom of the piston plate 81 and the bottom of the sealing groove 82. The other end of the support rod 83 away from the piston plate 81 penetrates through the top of the support block 54 and extends above the support block 54. An exhaust pipe 85 communicating with the upper part of the sealing groove 82 is fixedly connected to the outer wall of the support block 54. A plurality of air outlet holes 86 for blowing air on the connection location of the wax mold are arranged on the exhaust pipe 85.

[0057] During actual use, when the extrusion plate 35 pushes the heating plate 47 and the limit block 46 to move downward inside the limit sliding groove 45, the heating plate 47 will push the support rod 83 to drive the piston plate 81 to move downward inside the sealing groove 82 and compress the third elastic member 84. During the process of the piston plate 81 moving downward inside the sealing groove 82, external air will be drawn into the sealing groove 82 through the multiple air outlets 86 and the exhaust pipe 85. When the heating plate 47 completes the heating of the wax mold and moves away from above the support rod 83, the piston plate 81 will gradually move upward inside the sealing groove 82 under the rebound action of the third elastic member 84 and squeeze the air inside the sealing groove 82, so that the air is sprayed toward the bonding place of the wax mold through the exhaust pipe 85 and the multiple air outlets 86, accelerating the solidification speed of the wax liquid and improving the bonding efficiency.

[0058] In summary, through the setting of the auxiliary cooling mechanism 8, when the extrusion plate 35 pushes the heating plate 47 to move downward, it will synchronously push the support rod 83 to drive the piston plate 81 to draw external air into the sealing groove 82. When the heating plate 47 completes the heating of the wax mold and moves away from above the support rod 83, the piston plate 81 will gradually move upward inside the sealing groove 82 under the rebound action of the third elastic member 84 and squeeze the air inside the sealing groove 82, so that the air is sprayed toward the bonding place of the wax mold through the exhaust pipe 85 and the multiple air outlets 86, accelerating the solidification speed of the wax liquid and improving the bonding efficiency, and the bonding surface of the runner wax mold can be flipped earlier, thereby further improving the working efficiency.
