Abstract
Description
Technical Field
[0001] This utility model relates to the field of blade production technology, specifically to a baking device for producing blades that prevents deformation. Background Technology
[0002] An impeller can refer to a wheel disk with moving blades, which is a component of the rotor of an impulse steam turbine, or it can refer to the wheel disk and the rotating blades mounted on it. It can be classified according to its shape and opening / closing status. The blades of the impeller need to be baked during the production process. In general, the forming of blades is a complex and delicate process that requires comprehensive consideration of various factors and selection of appropriate forming technology to ensure the quality and performance of the blades.
[0003] The production process of impeller blades requires the use of aluminum molds and blades. First, thermosetting resin sand is used to shape the impeller blades, and then they need to be baked in an oven until the resin sand is completely hardened.
[0004] Current technology typically involves placing an aluminum mold and thermosetting resin sand blades together in an oven for baking. However, once the resin sand has fully hardened, the baked blades are extremely difficult to remove from the aluminum mold. Forcing them out can easily damage and deform the sand, affecting the blades' performance. Alternatively, workers might remove the blades from the aluminum mold first and then place them directly into the oven for baking. However, without any support or protection during baking, the blades are prone to deformation, leading to dimensional errors in the impeller blades. In some cases, the mold with significant errors needs to be remade, further impacting the blades' performance. Therefore, it is necessary to propose a deformation-resistant baking device for blade production to address these issues. Utility Model Content
[0005] The purpose of this invention is to provide a baking device for producing blades that prevents deformation, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A baking device for producing blades with anti-deformation properties includes a baking oven. Inside the baking oven is a lower pad, and an upper pad is attached to the top of the lower pad. The interior of the lower pad is used to hold the blade body, which is snapped into the interior of the upper pad. Both the lower and upper pads are made of wood. Slides are provided on both sides of the lower pad. A first limiting block is fixedly installed on the two side surfaces of the lower pad at both ends of each slide. A pin is inserted into the outer end of each first limiting block, and each pin engages with the interior of each slide. A limiting component is provided on the top of each slide, and each limiting component is used to compress and limit the space between the upper and lower pads. A second limiting block is fixedly installed on the two side surfaces of the lower pad at the top of each first limiting block.
[0008] Currently, baking aluminum molds and thermosetting resin sand blades together in an oven is problematic. After the resin sand hardens completely, the baked blades are extremely difficult to remove from the aluminum mold. Forcing them out easily damages and deforms the sand, affecting the blades' performance. Alternatively, the blades can be removed from the aluminum mold first and then placed directly into the oven for baking. However, without support during baking, the blades are prone to deformation, leading to dimensional errors in the impeller blades. In some cases, large errors necessitate remaking the entire model, still impacting the blades' performance. This application addresses this issue by removing the blade body from the aluminum mold, inserting it into a lower pad, and then attaching an upper pad to the top of the blade body. The outer periphery can limit the movement of the blade body. After the lower and upper pads are placed inside the baking oven, the wooden pads, with their thermal conductivity, transfer the heat generated by the oven to the blade body during baking. This reduces the possibility of blade deformation and improves the baking effect. Furthermore, the upper and lower pads prevent jamming between the blade body and the pads. After baking, the blade body can be quickly removed by separating the upper and lower pads, preventing damage or deformation during the feeding process and further reducing the likelihood of deformation and improving the baking effect.
[0009] A further improvement of the present invention is that each limiting component includes a support plate, each support plate is fixedly connected to the top surface of each slide plate, each support plate has a screw mounted on its top via a bearing, each screw has a movable plate threaded onto its outer surface, each movable plate has a limiting plate fixedly connected to its inner surface, and each limiting plate has its bottom surface pressed against the top surface of the upper pad.
[0010] In the above-mentioned technical solution, after the lower pad and the upper pad are attached, the upper pad is prone to sliding and separating from the lower pad, which affects the performance of the blade body. In this application, by rotating the screw, the movable plate can be moved to the bottom, and at the same time, the bottom surface of the limiting plate is attached to the upper pad and the upper pad is squeezed, thereby limiting the upper pad and the lower pad, preventing misalignment between the upper pad and the lower pad and affecting the limiting effect on the blade body, further reducing the possibility of blade body deformation and improving the baking effect of the blade body; by removing the plug, the slide plate is separated from the first limiting block, and then the slide plate is moved to the top, and then the plug is inserted into the interior of the second limiting block and the slide plate, which makes it easy to remove the upper pad.
[0011] A further improvement of this utility model is that a number of first through holes are provided inside the lower pad plate at the bottom of the blade body.
[0012] In the above-mentioned technical solution, during the baking process, the blade body may release some gas or steam. This gas and steam will be discharged to the inner walls of the lower and upper pads, resulting in increased humidity in some areas of the lower and upper pads. During the baking process, the lower and upper pads are prone to denting and deformation, which in turn can easily lead to deformation of the blade body. In this application, by opening a first through hole on the surface of the lower pad, some gas or steam released by the blade body can be discharged through the first through hole, preventing gas and steam from remaining inside the lower pad and causing denting and deformation, thereby further reducing the possibility of deformation of the blade body.
[0013] A further improvement of this utility model is that a number of second through holes are provided inside the upper pad plate at the top of the blade body.
[0014] In the above-mentioned technical solution, during the baking process of the blade body, some gases or vapors may be released. These gases and vapors will be discharged to the inner walls of the lower and upper pads, resulting in increased humidity in some areas of the lower and upper pads. During the baking process, the lower and upper pads are prone to denting and deformation, which in turn can easily lead to deformation of the blade body. In this application, by opening a second through hole on the surface of the upper pad, some gases or vapors released by the blade body can be discharged through the second through hole, preventing gases and vapors from remaining inside the upper pad and causing them to dent and deform, thereby further reducing the possibility of deformation of the blade body.
[0015] A further improvement of this utility model is that a handle is fixedly installed on the top of the upper pad.
[0016] By adopting the above technical solution, the contact area between the operator's hand and the upper pad can be increased by installing a handle, which makes it easier to separate the upper pad from the lower pad and further facilitates the removal of the blade body.
[0017] A further improvement of this utility model is that: a number of locking blocks are fixedly installed at the bottom of the lower pad, and a number of fixing blocks are fixedly connected inside the baking oven at the bottom of each lower pad, with each fixing block engaging with the inner wall of each locking block.
[0018] By using the above technical solution, the position of the lower pad inside the baking oven can be limited by inserting the card block into the fixed block, preventing the lower pad from sliding in the horizontal direction and causing the blade body to collide, thereby affecting the baking of the blade body.
[0019] A further improvement of this utility model is that: each card block has an opening at its bottom that is larger than the cross-sectional area of the top surface of each fixing block.
[0020] By adopting the above technical solution, the opening of the card block is set to be larger than the cross-sectional area of the fixed block, which makes it easier for the card block to be aligned with the outer surface of the fixed block, so that the card block can be inserted into the periphery of the fixed block to limit the position of the lower pad.
[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0022] 1. This utility model provides a baking device for producing blades that prevents deformation. After the blade body is removed from the aluminum template, it is positioned between the lower and upper pads to limit its movement. The wooden pads have thermal conductivity, allowing the heat generated in the baking oven to be transferred to the blade body during baking, thus reducing the possibility of deformation and improving the baking effect. After baking, the upper and lower pads can be separated to quickly remove the blade body, preventing damage or deformation during the unloading process, further reducing the possibility of deformation and improving the baking effect.
[0023] 2. This utility model provides a baking device for producing blades that prevents deformation. By setting a limiting component, the screw can drive the movable plate to squeeze the upper pad, thereby preventing misalignment between the upper and lower pads and affecting the limiting effect on the blade body. This further reduces the possibility of deformation of the blade body and improves the baking effect of the blade body.
[0024] 3. This utility model provides a baking device for preventing deformation in blade production. During the baking process, by opening a first through hole on the surface of the lower pad and a second through hole on the surface of the upper pad, some gases or steam released by the blade body during the baking process can be discharged through the first and second through holes, preventing gases and steam from remaining inside the upper and lower pads and causing them to dent and deform, thereby further reducing the possibility of deformation of the blade body.

[0033] The present invention will be further described in detail below with reference to embodiments:
[0034] Example 1
[0035] like Figure 2 , Figure 4 and Figure 6As shown, this utility model provides a baking device for producing blades to prevent deformation, including a baking oven 1; a lower pad 2 is placed inside the baking oven 1, and an upper pad 3 is attached to the top of the lower pad 2. The interior of the lower pad 2 is used to place the blade body 8, which is snapped into the interior of the upper pad 3. Both the lower pad 2 and the upper pad 3 are made of wood. Slide plates 13 are provided on both sides of the lower pad 2. A first limiting block 11 is fixedly installed on both sides of the lower pad 2 at both ends of each slide plate 13. A plug 14 is inserted into the outer end of each first limiting block 11. Each plug 14 is respectively engaged with the interior of each slide plate 13. A limiting component 5 is provided on the top of each slide plate 13. Each limiting component 5 is used to squeeze and limit the space between the upper pad 3 and the lower pad 2. A second limiting block 12 is fixedly installed on both sides of the lower pad 2 at the top of each first limiting block 11.
[0036] In this embodiment, currently, by directly placing the aluminum model and the thermosetting resin sand blades into an oven for baking, it becomes extremely difficult to remove the baked blades from the aluminum model after the resin sand has completely hardened. Forcing their removal can easily damage and deform the sand, affecting the blades' performance. Alternatively, the blades can be removed from the aluminum model first and then placed directly into the oven for baking. However, during baking, the blades lack support and protection, making them prone to deformation and resulting in impeller blade size errors. In some cases, models with large errors need to be remade, still affecting the blades' performance. In this application, after removing the blade body 8 from the aluminum template, the blade body 8 is inserted into the lower pad 2, and then the upper pad 3 is attached to the outer periphery of the top of the blade body 8. The blade body 8 is positioned to limit its movement. After the lower pad 2 and upper pad 3 are placed inside the baking oven 1, the wooden pads have a certain thermal conductivity and can transfer the heat generated by the baking oven 1 to the blade body 8 during the baking process. This reduces the possibility of deformation of the blade body 8 and improves the baking effect. Furthermore, the upper pad 3 and lower pad 2 will not jam the blade body 8. After the blade body 8 is baked, the upper pad 3 and lower pad 2 can be separated to quickly remove the blade body 8, preventing damage or deformation of the blade body 8 during the feeding process. This further reduces the possibility of deformation of the blade body 8 and improves the baking effect of the blade body 8.
[0037] Example 2
[0038] like Figure 2 , Figure 4 and Figure 5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, each limiting component 5 includes a support plate 501, each support plate 501 is fixedly connected to the top surface of each slide plate 13, each support plate 501 has a screw 503 rotatably mounted on its top via a bearing, each screw 503 has a movable plate 502 threadedly mounted on its outer surface, each movable plate 502 has a limiting plate 504 fixedly connected to its inner surface, and each limiting plate 504 has its bottom surface pressed against the top surface of the upper pad 3.
[0039] In this embodiment, after the lower pad 2 and the upper pad 3 are attached, the upper pad 3 is prone to sliding and separating from the lower pad 2, which affects the performance of the blade body 8. In this application, by rotating the screw 503, the movable plate 502 can be moved to the bottom, and at the same time, the bottom surface of the limiting plate 504 is attached to the upper pad 3 and pressed against the upper pad 3, thereby limiting the upper pad 3 and the lower pad 2, preventing misalignment between the upper pad 3 and the lower pad 2 from affecting the limiting effect on the blade body 8, further reducing the possibility of deformation of the blade body 8, and improving the baking effect of the blade body 8. By removing the plug 14, the slide plate 13 is separated from the first limiting block 11, and then the slide plate 13 is moved to the top. Then the plug 14 is inserted into the interior of the second limiting block 12 and the slide plate 13, which makes it easier to remove the upper pad 3.
[0040] Example 3
[0041] like Figure 2 , Figure 4 and Figure 6 As shown, based on Embodiment 2, this utility model provides a technical solution: preferably, the lower pad 2 at the bottom of the blade body 8 is provided with a plurality of first through holes 7, the upper pad 3 at the top of the blade body 8 is provided with a plurality of second through holes 9, and a handle 10 is fixedly installed on the top of the upper pad 3.
[0042] In this embodiment, during the baking process, the blade body 8 may release some gas or vapor. This gas and vapor will drain to the inner walls of the lower pad 2 and the upper pad 3, resulting in increased humidity in some areas of the lower pad 2 and the upper pad 3. During the baking process, the lower pad 2 and the upper pad 3 are prone to denting and deformation, which in turn can easily lead to deformation of the blade body 8. In this application, by opening a first through hole 7 on the surface of the lower pad 2 and a second through hole 9 on the surface of the upper pad 3, it is possible to facilitate the discharge of some gas or vapor released by the blade body 8 through the first through hole 7 and the second through hole 9, preventing gas and vapor from remaining inside the upper pad 3 and the lower pad 2 and causing them to dent and deform, thereby further reducing the possibility of deformation of the blade body 8. By installing a handle 10, the contact area between the operator's hand and the upper pad 3 can be increased, thereby facilitating the separation of the upper pad 3 and the lower pad 2, and further facilitating the removal of the blade body 8.
[0043] Example 4
[0044] like Figure 2 , Figure 3 and Figure 5 As shown, based on embodiment 3, this utility model provides a technical solution: preferably, a plurality of locking blocks 4 are fixedly installed at the bottom of the lower pad 2, and a plurality of fixing blocks 6 are fixedly connected inside the baking oven 1 at the bottom of each lower pad 2. Each fixing block 6 is engaged with the inner wall of each locking block 4, and the bottom of each locking block 4 has an opening larger than the cross-sectional area of the top surface of each fixing block 6.
[0045] In this embodiment, by inserting the locking block 4 into the interior of the fixing block 6, the position of the lower pad 2 inside the baking oven 1 can be limited, preventing the lower pad 2 from sliding in the horizontal direction and causing the blade body 8 to collide, thereby affecting the baking of the blade body 8; by setting the opening of the locking block 4 to be larger than the cross-sectional area of the fixing block 6, it is easy to align the locking block 4 with the outer surface of the fixing block 6, so that the locking block 4 can be inserted into the periphery of the fixing block 6 to limit the position of the lower pad 2.
[0046] The working principle of the baking device for producing anti-deformation blades is explained in detail below.
[0047] like Figures 1-6As shown, the operator removes the plug 14, moves the slide plate 13 to the top, and then inserts the plug 14 into the second limiting block 12 and the slide plate 13. Next, the operator removes the upper pad 3, inserts the blade body 8 into the lower pad 2, and then snaps the upper pad 3 onto the periphery of the blade body 8, fitting the lower pad 2 against the upper pad 3. Then, the operator removes the plug 14, moves the slide plate 13 to the bottom, and inserts the plug 14 into the first limiting block 11 and the slide plate 13. Finally, the operator rotates the screw 503, simultaneously moving the movable plate 502 to the bottom and squeezing the upper pad 3. The pressure is applied to limit the movement between the upper pad 3 and the lower pad 2. The operator places the lower pad 2 inside the baking oven 1 and inserts each clip 4 onto the outer surface of each fixing block 6 to limit the movement of the lower pad 2, so as to facilitate the baking of the blade body 8. After baking, the operator can remove the plug 14 to separate the slide plate 13 from the first limiting block 11, then move the slide plate 13 to the top, insert the plug 14 into the second limiting block 12 and the slide plate 13, then remove the upper pad 3, and finally remove the blade body 8.
[0048] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
