Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for a fan housing. Background Technology

[0002] With the continued growth of the global economy and the increasing demand for clean energy, wind turbines, as one of the core components of wind power generation, have seen their market size expand year by year. Meanwhile, in the industrial sector, wind turbines are widely used for ventilation, heat dissipation, and dust removal, leading to a continuous increase in demand. To meet the needs of large-scale wind turbine production, efficient and high-quality manufacturing processes and equipment are required. Stamping die technology, due to its high efficiency and high precision, has been widely used in the manufacturing of wind turbine casings.

[0003] Currently, one type of stamping die for a wind turbine casing is difficult to replace. During the stamping process, there is intense friction and extrusion between the die and the sheet metal, especially at the cutting edge of the die, which is prone to wear. The working conditions of the stamping die for the wind turbine casing are quite harsh. As the number of stamping cycles increases, the wear of the die will gradually intensify. This will not only affect the quality of the stamped parts, but also shorten the service life of the die. It has significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the shape of the fan blades is irregular and the two ends of the clamping may not be on the same plane, resulting in unstable clamping and poor practicality. In addition, when collecting the powder generated during grinding, a fan is usually used to suck it up, but the traditional fan sucks up the powder in a fixed position, resulting in poor suction effect. Therefore, a fan shell stamping mold is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fan housing stamping die, comprising a main board, a bracket fixed to the top of the main board, a hydraulic push rod mounted on the top of the bracket, a housing fixed to the output end of the hydraulic push rod and the top of the main board, a die body placed at one end of each of the two housings, a module placed at one end of each of the two die bodies, connecting plates provided on both sides of the die body, a locking block fixed at one end of each of the two connecting plates, and the locking blocks penetrating through both sides of the die body and inserted into the inner sides of both ends of the module at one end, a baffle fixed on the outer wall of the locking block on the outer side of the die body, and a driving structure for driving the two locking blocks to move in opposite directions within the housing.

[0006] Preferably, the drive structure includes a first motor disposed on one side of the housing, the output end of the first motor passing through one side of the housing and fixed with a bidirectional screw, both ends of the outer wall of the bidirectional screw being threadedly connected with movable blocks, both ends of the two movable blocks being slidably connected with limit posts, both opposite ends of the two movable blocks being fixed with connecting blocks, both opposite ends of the two connecting blocks passing through the housing and respectively fixed with support blocks, and one end of the two connecting plates being respectively fixed to the two support blocks.

[0007] Preferably, a base is provided below the motherboard, and a second motor is installed at the top of the base, with the output end of the second motor fixed to the motherboard.

[0008] Preferably, the base has four legs evenly distributed at its bottom end, and each of the four legs has a first electric telescopic rod installed on its inner top wall. The output end of each of the four first electric telescopic rods is fixed with a column that matches the inner wall of the leg.

[0009] Preferably, a stabilizing plate is rotatably connected between the base and the main board, located outside the second motor.

[0010] Preferably, the end of the bidirectional screw away from the first motor is fixed with a rotating shaft, which is located inside the housing and rotatably connected to the housing.

[0011] Preferably, both ends of the limiting post are fixed to the machine box, and both ends of the module and the mold body are provided with slots that match the card block.

[0012] Preferably, a connecting hole is provided on the inner wall of the module, and a second electric telescopic rod is installed on the inner wall of the connecting hole. A push plate is fixed to the output end of the second electric telescopic rod.

[0013] Preferably, a fixing frame is fixed at one end of the housing, the first motor is installed at the end of the fixing frame facing the housing, and openings matching the connecting blocks are provided at both ends of the housing.

[0014] Preferably, each of the two machine boxes has a guide block fixed at one end facing each other, and each of the two mold bodies has a guide groove matching the guide block at one end facing away from each other.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, the operation of the first motor drives the bidirectional screw to rotate, causing the two moving blocks to move towards or away from each other under the limitation of the limiting post. This, in turn, drives the two supporting blocks connected to the two connecting blocks to move towards or away from each other, and in turn drives the two locking blocks connected to the two connecting plates to move towards or away from each other. When the two locking blocks move out of the slots opened at both ends of the mold body and the module, they no longer limit the mold body and the module. The user can directly remove the mold body and the module inside it to replace both at the same time. When only the module needs to be replaced, only the two locking blocks need to move out of the slots at both ends of the module, making it more practical. Attached Figure Description

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, such as Figure 1-5 As shown, this utility model provides a stamping die for a fan housing, including a main board 1. A bracket 21 is fixed to the top of the main board 1. A hydraulic push rod 2 is installed at the top of the bracket 21. A housing 3 is fixed to the output end of the hydraulic push rod 2 and the top of the main board 1. A die body 4 is placed at one of the opposite ends of the two housings 3. A module 5 is placed at one of the opposite ends of the two die bodies 4. A connecting plate 6 is provided on both sides of the die body 4. A locking block 7 is fixed at one of the opposite ends of the two connecting plates 6. The opposite ends of the two locking blocks 7 pass through both sides of the die body 4 and are inserted into the inner sides of the two ends of the module 5. A baffle 8 is fixed on the outer wall of the locking block 7 located on the outer side of the die body 4. A driving structure 10 for driving the two locking blocks 7 to move in opposite directions is provided inside the housing 3.

[0026] The overall effect of Embodiment 1 is that the operation of the hydraulic push rod 2 drives the upper mold body 4 to descend, so that it can stamp the plate placed on the lower mold body 4, so that the plate is extruded and formed according to the gap between the two modules 5, and finally becomes the shell of the fan. The operation of the drive structure 10 can drive the two connecting plates 6 to move in opposite directions, thereby driving the two locking blocks 7 to move in opposite directions. When the two locking blocks 7 move out of the locking slots 9 opened at both ends of the mold body 4 and the module 5, they no longer limit the mold body 4 and the module 5. The user can directly remove the mold body 4 and the module 5 inside it to replace both at the same time. When only the module 5 needs to be replaced, only the two locking blocks 7 need to move out of the locking slots 9 at both ends of the module 5, which is more practical. The setting of the baffle 8 can limit the position of the mold body 4, so as to achieve the effect of installing the mold body 4.

[0027] Example 2, as Figure 1-5As shown, the drive structure 10 includes a first motor 1001 located on one side of the housing 3. The output end of the first motor 1001 passes through one side of the housing 3 and is fixed with a bidirectional screw 1002. Both ends of the outer wall of the bidirectional screw 1002 are threadedly connected to moving blocks 1003. Both ends of the two moving blocks 1003 are slidably connected to limit posts 1004. The opposite ends of the two moving blocks 1003 are fixed with connecting blocks 1005. The opposite ends of the two connecting blocks 1005 pass through the housing 3 and are respectively fixed with support blocks 1006. One end of the two connecting plates 6 is respectively fixed to the two support blocks 1006. A base 15 is provided below the main board 1. A second motor 16 is installed at the top of the base 15. The output end of the second motor 16 is fixed to the main board 1. Four support legs 18 are evenly distributed at the bottom of the base 15. A first electric telescopic rod 19 is installed on the inner top wall of each of the four support legs 18. The output ends of the four first electric telescopic rods 19 are fixed to the inner walls of the support legs 18. A stabilizing plate 17 is rotatably connected between the wall-matching column 20, the base 15, and the main board 1, located outside the second motor 16. A rotating shaft 12 is fixed at the end of the bidirectional screw 1002 away from the first motor 1001. The rotating shaft 12 is located inside the housing 3 and rotatably connected to the housing 3. Both ends of the limiting column 1004 are fixed to the housing 3. Both ends of the module 5 and the mold body 4 are provided with slots 9 that match the card block 7. A connecting hole 22 is provided on the inner wall of the module 5. A second electric telescopic rod 23 is installed on the inner wall of the connecting hole 22. A push plate 24 is fixed at the output end of the second electric telescopic rod 23. A fixing frame 25 is fixed at one end of the housing 3. The first motor 1001 is installed at the end of the fixing frame 25 facing the housing 3. Both ends of the housing 3 are provided with openings 11 that match the connecting block 1005. Guide blocks 13 are fixed at the opposite ends of the two housings 3. Guide grooves 14 that match the guide blocks 13 are provided at the opposite ends of the two mold bodies 4.

[0028] The overall effect of Embodiment 2 is as follows: the operation of the first motor 1001 drives the bidirectional screw 1002 to rotate, causing the two moving blocks 1003 to move towards or away from each other under the limit of the limiting post 1004. This causes the two supporting blocks 1006 connected to the two connecting blocks 1005 to move towards or away from each other, thereby causing the two locking blocks 7 connected to the two connecting plates 6 to move towards or away from each other. The operation of the second motor 16 drives the main board 1 to rotate as a whole, allowing it to adjust its angle according to actual needs. The operation of the four first electric telescopic rods 19 drives the four columns 20 to rise and fall, thereby allowing the main board 1 to adjust its height according to actual needs. The operation of the second electric telescopic rod 23 drives the push plate 24 to rise and fall, thereby automatically pushing out the fan housing formed in the lower module 5. The setting of the stabilizing plate 17 provides auxiliary support for the main board 1, avoiding damage caused by the second motor 16 supporting the main board 1 alone, thus enhancing stability.

[0029] Working principle: When the device is in use, the operation of the hydraulic push rod 2 drives the upper mold body 4 to descend, causing it to press the sheet material placed on the lower mold body 4. The sheet material is extruded and formed according to the gap between the two modules 5, ultimately becoming the outer shell of the fan. The operation of the first motor 1001 drives the bidirectional screw 1002 to rotate, causing the two moving blocks 1003 to move towards or in opposite directions under the limit of the limiting post 1004. This causes the two supporting blocks 1006 connected by the two connecting blocks 1005 to move towards or in opposite directions, thereby causing the two locking blocks 7 connected by the two connecting plates 6 to move towards or in opposite directions. The operation of the two motors 16 can drive the main board 1 to rotate as a whole, allowing it to adjust its angle according to actual needs. The operation of the four first electric telescopic rods 19 can drive the four columns 20 to rise and fall, thereby driving the main board 1 to adjust its height according to actual needs. The operation of the second electric telescopic rod 23 can drive the push plate 24 to rise and fall, thereby automatically pushing out the fan housing formed in the lower module 5. The setting of the stabilizing plate 17 can provide auxiliary support for the main board 1, avoiding the problem of damage caused by the second motor 16 supporting the main board 1 alone, thus enhancing stability.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
