Description

Technical Field

[0001] This invention relates to the field of investment casting technology, specifically a device for suspending and shaping wax patterns. Background Technology

[0002] The moving blade is a key blade component installed on the rotor of a steam turbine or gas turbine. Its core function is to convert the kinetic and thermal energy of fluids (such as steam or gas) into mechanical work, thereby driving the rotor to rotate. It is produced by investment casting. After the moving blade wax model is removed from the mold, it needs to be trimmed and coated with a shell before being hung and dried to complete the shaping. The wax model also needs to be cleaned before coating the shell, and then hung to shape it to achieve its surface cleanliness, thereby ensuring the qualification rate of subsequent product production. Traditional wax model cleaning requires placing the wax model on a special fixture, then manually holding the fixture to place the wax model in a cleaning tank for cleaning, and finally placing it on a frame for hanging and shaping.

[0003] Existing technical solutions utilize suspended conveyor equipment to suspend the clamp holding the wax model. As the wax model moves, it passes through a cleaning tank, achieving rapid cleaning and reducing manual labor. Finally, the cleaned wax model is removed and placed on a frame for suspension and shaping. However, this technology still has the following drawbacks in practical use: the shapes of the moving blade wax models vary, requiring the manufacture of specialized shaping and suspension fixtures for each product. This makes operation cumbersome for workers, necessitating frequent fixture changes, and increases the time and effort required for workshop storage and maintenance, as well as manufacturing costs. While the clamps suspended on the suspended conveyor equipment can carry the wax model for cleaning as the equipment moves, once inside the cleaning tank, the wax model can only move along the direction of the equipment's movement, making it difficult to ensure efficient removal of attached residues, thus affecting the yield rate of subsequent product production. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, the present invention provides a device for suspending and shaping wax models. By considering the shaping method during mold design and designing hanging hooks in the excess space of the wax model, and standardizing the size of the hooks, it is convenient for the suspension components to clamp and suspend wax models of different shapes. The suspension components are equipped with lifting parts and auxiliary columns, combined with auxiliary components set on the main body of the suspended conveyor. When the main body of the suspended conveyor moves the various suspension components, when the suspension components come into contact with the auxiliary components, under the traction force generated by the operation of the main body of the suspended conveyor, the suspension components drive the wax models clamped on them to perform rotational lifting and lowering activities in the cleaning tank, thereby improving the cleaning effect on the outer surface of the wax models and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0012] As a further embodiment of the present invention, a receiving groove for accommodating an auxiliary column is provided at the center of the top of the movable platform. An arc-shaped closed groove is provided on the outer shell wall of the auxiliary column. A slider is slidably connected in the arc-shaped closed groove.

An inner textured cylinder is integrally provided on the front and rear sides of the receiving groove and located on the top shell wall of the movable platform. The inner textured cylinder is used to connect the lifting component.

[0013] Each inner cylinder has a through hole on the top plate directly above it. The lifting component includes a rod threaded into the inner cylinder. The top of the rod passes through the corresponding through hole and is connected to a ball bearing. Below the ball bearing is a positioning ring on the outer shell wall of the rod. A return spring on the rod is sleeved between the positioning ring and the top plate.

[0014] As a further embodiment of the present invention, the bottom of the shell is provided with a hole, the bottom end of the movable platform passes through the hole, and the bottom outer ring of the movable platform is also provided with a thread.

[0015] The clamping assembly includes a conical cylinder threaded to the movable platform, a base frame located below the conical cylinder, and the base frame and the conical cylinder connected by a splicing component. Two clamping components are symmetrically arranged on the base frame.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] By considering the shaping method during mold design and designing hanging hooks in the allowance of the wax model, the size of the hooks can be standardized to facilitate the clamping and hanging of wax models of different shapes. This improves the versatility of the hanging components, saves the cost of designing, manufacturing and storing different hangers, and reduces the operational burden on workers. Moreover, this method is simple and easy to promote.

[0025] The suspension components are equipped with lifting parts and auxiliary columns. Combined with the auxiliary components set on the main body of the suspension conveyor, when the main body of the suspension conveyor moves each suspension component, when the suspension component comes into contact with the auxiliary components, under the traction force generated by the operation of the main body of the suspension conveyor, the suspension component drives the wax mold held on it to rotate and lift in the cleaning tank, thereby improving the cleaning effect on the outer surface of the wax mold.

[0026] Along the running direction of the main body of the suspended conveyor, a drying component is installed on the right side of the cleaning tank. Convection hot air is used to dry the wax molds that have been cleaned and drained, reducing the problem of excessive water dripping when the wax molds are suspended and shaped on the frame, which would affect the surrounding environment. This also further accelerates the shaping speed of the wax molds and ensures the efficiency of subsequent processes. Attached Figure Description

[0036] Please see Figures 1-2 In this embodiment of the invention, a device for suspending and shaping wax molds includes a base plate 1, a main body 2 of a suspended conveyor equipment, and a cleaning tank 5. The cleaning tank 5 includes two tanks for multiple cleanings of the wax molds, thereby improving the cleaning effect on the outer surface of the wax molds.

[0037] The main body 2 of the suspended conveyor is equipped with multiple suspension components 3 for clamping wax molds, and two auxiliary components 4 are also installed on the main body 2 of the suspended conveyor, which correspond to the corresponding cleaning tanks 5. The auxiliary components 4 are used to contact and adjust the suspension components 3.

[0038] When the suspended component 3 reaches the position of the cleaning pool 5 as the main body 2 of the suspended conveyor moves along with the suspended conveyor 2, the traction force generated by the movement of the main body 2 causes the suspended component 3 to move continuously to the right. At this time, the suspended component 3 comes into contact with the auxiliary component 4. Since the suspended component 3 moves to the right under the traction force generated by the main body 2 of the suspended conveyor, and the wax mold on the suspended component 3 is in the clean water, the clean water has a certain buffering effect on it. Thus, when the suspended component 3 comes into contact with the auxiliary component 4, it can ensure that the suspended component 3 drives the wax mold to rotate and move downward.

[0039] The base plate 1 is located directly below the main body 2 of the suspended conveyor equipment. Two cleaning pools 5 are arranged on the base plate 1 from left to right. The continuous arrangement of the two cleaning pools 5 ensures the high efficiency of cleaning the wax mold.

[0040] A liquid collection tank 6 is also provided on the right side of the cleaning tank 5. A guide channel 7 located on the bottom plate 1 is placed on the right side of the liquid collection tank 6. The guide channel 7 is used to collect the liquid dripping from the wax model. The arrangement of the guide channel 7 and the liquid collection tank 6 collects the liquid dripping from the wax model after cleaning, avoiding water splashing and affecting the surrounding working environment. In addition, this area is the draining area of ​​the wax model, which facilitates the subsequent drying treatment of the drying component 8.

[0041] A drying component 8 is provided on the right side of the flow channel 7 and located on the base plate 1. The drying component 8 is used to dry the wax model, accelerate the drying and shaping speed of the wax model, and save the shaping time after cleaning.

[0042] Please see Figures 2-4 In this embodiment of the invention, the suspension component 3 includes a top plate 31, a U-shaped rod 32, an auxiliary column 33, a housing 34, a movable platform 35, a lifting component 36, and a clamping assembly 37. The U-shaped rod 32 is welded to the top of the top plate 31. The auxiliary column 33 and the housing 34 are both fixedly connected to the bottom housing wall of the top plate 31 by bolts. The auxiliary column 33 is located at the bottom center of the U-shaped rod 32. The movable platform 35 is movably connected to the housing 34, and the movable platform 35 is also movably connected to the auxiliary column 33. The movable platform 35 includes a ring and a moving rod. The top end of the moving rod is rotatably connected to the inner ring housing wall of the ring.

[0043] The lifting component 36 includes two parts, which are symmetrically arranged on the ring of the movable table 35. The top of the lifting component 36 passes through the top plate 31. The clamping component 37 is threadedly connected to the moving bar of the movable table 35 and is used to clamp the wax model.

[0044] Please see Figures 1-2In this embodiment of the invention, the cleaning pool 5 is composed of a pool box and support legs. The support legs include four legs, arranged in pairs, and are respectively set on the outer walls of both sides of the pool box. A splicing plate is provided between the two pool boxes to cover the gap between the two pool boxes. Thus, when the wax model located on the suspension component 3 leaves the first cleaning pool 5 and enters the second cleaning pool 5, the liquid dripping on it is guided to reduce the splashing of liquid and protect the surrounding working environment.

[0045] Each tank has an inlet pipe for filling with clean water and an outlet pipe for discharging wastewater installed on its rear shell wall. Both the inlet and outlet pipes are equipped with control valves. The inlet pipes of the two cleaning tanks 5 are connected to a main pipe, which is connected to an external water pump body. When the water pump body is running, it fills the inlet pipe with clean water. The water supply in the corresponding cleaning tank 5 is controlled by opening and closing the corresponding control valves.

[0046] The control valve on the outlet pipe controls the discharge of wastewater during water replacement in the cleaning tank 5.

[0047] The liquid collection tank 6 is located below the right side tank and is fixedly connected to multiple support legs by bolts. It is used to collect dripping liquid, and a drain pipe for cleaning is provided on the rear shell wall of the liquid collection tank 6.

[0048] The flow channel 7 is composed of a flow channel and support columns. The support columns include multiple columns arranged in a matrix on the bottom shell wall of the flow channel, and the bottom of the support columns is placed on the base plate 1. The flow channel is lower on the left and higher on the right, and the left side of the flow channel extends into the liquid collection tank 6. The inclined design of the flow channel can facilitate the flow and collection of dripping liquid.

[0049] Please see Figure 1 and Figure 8 In this embodiment of the invention, the drying component 8 includes two side plates 81 symmetrically arranged on the base plate 1. Each side plate 81 has a serpentine tube 82 on its inner wall and a plurality of air nozzles for hot air discharge on each serpentine tube 82. The serpentine tubes 82 on the two side plates 81 are arranged opposite to each other, thereby creating a convection effect for the hot air blown on them.

[0050] A hot air blower body 83 located on the base plate 1 is provided between the two side plates 81. A hot air channel 84 is installed at the output end of the hot air blower body 83, and the two output ends of the hot air channel 84 are respectively installed on the corresponding serpentine tubes 82.

[0051] Please see Figures 3-7In this embodiment of the invention, a receiving groove for accommodating the auxiliary column 33 is provided at the top center of the active platform 35. The receiving groove is located at the top center of the exercise bar. An arc-shaped closed groove is provided on the outer shell wall of the auxiliary column 33. A slider is slidably connected in the arc-shaped closed groove. An L-shaped seat is fixedly connected to the outer wall of the slider. The top of the L-shaped seat is fixedly connected to the top shell wall of the exercise bar by bolts. An inner textured cylinder is integrally provided on the front and rear sides of the receiving groove and located on the top shell wall of the ring. The inner textured cylinder is used to connect the lifting component 36.

[0052] Each inner cylinder has a through hole on the top plate 31 directly above it. The lifting component 36 includes a rod that is threaded into the inner cylinder. The top of the rod passes through the corresponding through hole and is connected to a ball. A positioning ring is located on the outer shell wall of the rod below the ball. A return spring is sleeved between the positioning ring and the top plate 31 on the rod.

[0053] When the lifting component 36 moves up and down, it synchronously drives the movable platform 35 to move. At this time, the ring in the movable platform 35 moves linearly, and the moving rod connected to the inner shell wall of the ring rotates during the lifting and lowering process with the help of the arc-shaped closed groove and the slider on the auxiliary column 33.

[0054] The bottom of the cover 34 has a hole, the bottom of the movable platform 35 passes through the hole, and the bottom outer ring of the moving rod is also threaded.

[0055] The clamping assembly 37 includes a cone 371 threadedly connected to the moving bar, a base frame 372 provided below the cone 371, the base frame 372 and the cone 371 are connected by a splicing piece, and two clamping pieces 373 are symmetrically arranged on the base frame 372.

[0056] The splicing component consists of two fixed arm assemblies, which are arranged in a cross shape on the outer shell wall of the cone 371, and the bottom of both fixed arm assemblies are welded to the base frame 372.

[0057] The fixed arm assembly consists of two symmetrically arranged fixed arms.

[0058] The clamping component 373 includes a sliding sleeve 3731, a carrier plate 3732, a limiting component 3733, a lifting rod 3734, an integrated plate 3735, a support arm 3736, a clamping roller 3737, and an adjusting component 3738. There are two sliding sleeves 3731, which are symmetrically slidably connected to the base frame 372. The carrier plate 3732 is located on top of the two sliding sleeves 3731 and is fixedly connected to the sliding sleeves 3731 by bolts.

[0059] Two slots are symmetrically opened on the top shell wall of the carrier plate 3732. There are two lifting rods 3734, which pass through the corresponding slots respectively. The integrated plate 3735 is located at the top of the two lifting rods 3734 and is fixed to the lifting rods 3734 by bolts.

[0060] The limiting component 3733 includes a lead screw 37331 rotatably connected to the side wall of the carrier plate 3732 via a bearing. A connecting plate 37332 is movably connected to the lead screw 37331. U-shaped constraint frames 37333 are fixedly connected to both ends of the connecting plate 37332 by bolts. The U-shaped constraint frames 37333 are used to constrain the corresponding lifting rods 3734.

[0061] Below each slot are two openings located on the side wall of the carrier plate 3732. These openings are for the passage of the U-shaped constraint frame 37333. Between the two openings is an arc-shaped abutment located on the corresponding side wall of the carrier plate 3732, which works with the U-shaped constraint frame 37333 to achieve tight restraint on the lifting rod 3734.

[0062] The support arm 3736 includes two arms, which are respectively fixedly connected to the bottom end of the corresponding lifting rod 3734 by bolts. The clamping roller 3737 is located between the two support arms 3736, and the two ends of the clamping roller 3737 pass through the corresponding support arm 3736 respectively.

[0063] When the height of the clamping roller 3737 is adjusted, the limiting component 3733 is first adjusted so that the two U-shaped constraint frames 37333 can release the limiting lock on the corresponding lifting rod 3734. Then, the two lifting rods 3734 are raised and lowered synchronously through the connecting plate 37332. Then, under the action of the support arm 3736, the clamping roller 3737 is driven to adjust its height. After the adjustment is completed, the limiting component 3733 is adjusted again, and the U-shaped constraint frame 37333 limits and locks the corresponding lifting rod 3734 to ensure the height of the clamping roller 3737.

[0064] The adjusting component 3738 includes a mounting hole opened on the end wall of the base frame 372. An inner threaded tube 37381 is rotatably connected to the mounting hole via a bearing. A threaded rod 37382 is threadedly connected to the inner threaded tube 37381. A splicing arm 37383 is fixedly connected to the end of the threaded rod 37382 away from the inner threaded tube 37381. The top of the splicing arm 37383 is fixedly connected to the corresponding carrier plate 3732 by bolts.

[0065] First, based on the shape of the wax model to be clamped, the corresponding adjusting parts 3738 in the two clamping parts 373 are adjusted. By adjusting the inner groove tube 37381 in the adjusting part 3738, the threaded rod 37382 is moved. The carrier plate 3732 is displaced by the splicing arm 37383, thereby pre-adjusting the position of the clamping rollers 3737 on both sides. Then, the wax model to be clamped is placed on the two clamping rollers 3737. Next, the corresponding adjusting parts 3738 are finely adjusted to achieve stable clamping of the wax model.

[0066] Please see Figures 1-3 In this embodiment of the invention, the auxiliary component 4 includes a U-shaped plate 41 and a wave plate 42. There are two wave plates 42, which are respectively fixedly connected to the bottom ends of the U-shaped plate 41, and the U-shaped plate 41 is fixedly connected to the main body 2 of the suspended conveyor by bolts.

[0067] The bottom of the wave plate 42 rolls into contact with the balls on the lifting component 36. As the suspension component 3 moves with the main body 2 of the suspension conveyor, when the lifting component 36 on it contacts the wave plate 42, the auxiliary column 33 is used to achieve the rotational lifting adjustment of the movable table 35, thereby driving the clamping component 37 and the wax mold on it to be rotated and cleaned in the cleaning pool 5.

[0068] The working principle of this invention is as follows: When cleaning the wax model, the worker first starts the suspended conveyor body 2 and the drying component 8 through the external controller body, and opens the control valve on the water inlet pipe in each cleaning tank 5, driving the external water pump body to inject clean water into the cleaning tank 5. After the clean water in each cleaning tank 5 is injected to the appropriate position, the corresponding control valve is closed through the external controller body, and then the external water pump body is turned off, thus completing the preparation work.

[0069] Next, the wax model to be processed is clamped by the suspension component 3, and then the suspension component 3 holding the wax model is placed on the hook on the main body 2 of the suspended conveyor. The operation of the main body 2 of the suspended conveyor drives the suspension component 3 holding the wax model to move, so that the wax model can pass through each cleaning pool 5 to achieve its cleaning treatment.

[0070] When the suspension component 3 clamps the wax model, it adjusts the two clamping parts 373 in the clamping assembly 37 according to the pre-reserved hook position on the wax model. First, it adjusts the height of the clamping roller 3737 in the clamping part 373. Then, it rotates the lead screw 37331 in the limiting part 3733, which moves the connecting plate 37332 threaded onto it, causing the two U-shaped constraint frames 37333 to move and release the clamping lock on the corresponding lifting rod 3734. At this time, the lifting rod 3734 is adjusted by the integration plate 3735. The adjustment of the lifting rod 3734 allows the support arm 3736 and the clamping roller 3737 on it to adjust their height. After the adjustment is completed, the lead screw 37331 in the limiting part 3733 is rotated in the opposite direction. The two U-shaped constraint frames 37333 are moved by the connecting plate 37332, and the corresponding lifting rod 3734 is locked again.

[0071] After the height of the clamping roller 3737 is adjusted, the adjusting member 3738 in the two clamping members 373 will be adjusted according to the shape of the wax model to be clamped, so as to achieve the pre-adjustment of the position of the two clamping rollers 3737. Then the wax model to be clamped is placed on the adjusted two clamping rollers 3737. Finally, the corresponding adjusting member 3738 is finely adjusted to achieve stable clamping of the wax model.

[0072] When the adjusting member 3738 in the two clamping members 373 is adjusted, it drives the threaded rod 37382 to move by adjusting its inner groove 37381. The splicing arm 37383 drives the corresponding carrier plate 3732 to move. At this time, the clamping roller 3737 on the carrier plate 3732 moves synchronously. With the movement of the clamping roller 3737, the wax mold on the two clamping rollers 3737 is stably clamped.

[0073] After the wax model is clamped by the suspension component 3, the suspension component 3 is suspended on the main body 2 of the suspension conveyor by contacting the hook on the suspension rod 32.

[0074] As the main body 2 of the suspended conveyor operates, the suspended component 3 suspended on it moves from left to right. When the suspended component 3 holding the wax model reaches the position of the first cleaning pool 5, due to the trajectory design of the main body 2, the wax model on the suspended component 3 is immersed in the water of the cleaning pool 5. Furthermore, the operation of the main body 2 creates a pulling force on the suspended component 3 to the right. When the suspended component 3 moves to the auxiliary component 4, the balls in the lifting parts 36 of the suspended component 3 contact the wave plate 42 in the auxiliary component 4. As the ball rolls along the wave plate 42, it works in conjunction with the return spring on the lifting component 36 to cause the lifting component 36 to reciprocate. When the lifting component 36 moves downward, it drives the movable platform 35 to move downward. The downward movement of the movable platform 35 causes the clamping component 37 on it to move downward, further pressing the wax model clamped on it towards the bottom of the cleaning tank 5. During the downward movement of the movable platform 35, due to the cooperation of the arc-shaped closed groove on the auxiliary column 33 and the corresponding slider, the movable platform 35 rotates synchronously during the downward movement, thereby causing the clamped wax model to rotate in the cleaning tank 5, further improving the cleaning effect of the wax model.

[0075] As the main body 2 of the suspended conveyor operates, the suspended component 3 passes through two cleaning pools 5 to efficiently clean the wax model. After being cleaned twice, the wax model continues to move to the right under the clamping of the suspended component 3. During the continuous displacement of the wax model after leaving the cleaning pool 5, the water droplets attached to it drip off under the action of gravity. At this time, the guide channel 7 guides the dripping water droplets into the collection tank 6 for collection. This stage achieves the draining treatment of water droplets on the wax model.

[0076] When the suspended component 3 arrives at the area where the drying component 8 is located along with the main body 2 of the suspended conveyor equipment, the hot air blown out by the hot air blower body 83 in the drying component 8 flows towards the two serpentine tubes 82 under the action of the hot air channel 84. Then, with the air discharged from each nozzle on the serpentine tubes 82, the area where the two side plates 81 are located is formed into a drying zone by the convective hot air. At this time, the wax mold that enters the drying zone moves under the drive of the main body 2 of the suspended conveyor equipment and is quickly dried after being dried by the convective hot air in the drying zone.

[0077] Finally, the staff removes the suspended component 3 from the main body 2 of the suspended conveyor after it leaves the drying area, and collects it and hangs it on the frame to stand still, thereby achieving the suspension and shaping of the wax model.

[0078] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
