Description

Technical Field

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

[0002] A stamping device for fan housing processing is a type of mechanical equipment specifically used for producing fan housings. It uses a stamping process to shape metal or plastic sheets into the required shape and structure for the fan housing. The material is formed in a mold using the stamping pressure of the stamping press.

[0003] After the fan housing is stamped, its outer bottom edge fits into the inside of the slot. The housing is then pushed outwards and lifted from the middle, while the side housing remains attached. Excessive lifting from the middle can cause the housing to bend, resulting in poor demolding. Additionally, stamping a relatively hard material housing can cause the material temperature to rise due to the high-intensity stamping, making removal after demolding somewhat dangerous. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stamping device for processing fan housings, which improves the demolding effect and reduces the risk of burns during demolding.

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

[0006] A stamping device for processing a fan housing includes a bottom support base for bottom support. A mounting support frame is fixedly connected to the top of the bottom support base. A stamping groove is formed in the middle of the top of the bottom support base. A hydraulic rod is fixedly connected to the middle of the bottom end of the mounting support frame. A stamping plate is fixedly connected to the output end of the hydraulic rod. An upper module is fixedly connected to the bottom end of the stamping plate. A main ejector column is slidably connected to the middle of the bottom support base. A threaded rod is rotatably connected to the middle of the inner side of the bottom support base. The external thread of the threaded rod is threaded into the interior of the main ejector column. A drive motor is fixedly connected to the bottom of the inner side of the bottom support base. The output end of the drive motor is fixedly connected to the bottom end of the main ejector column. The exterior of the main ejector column is connected to the interior of the bottom support base via a secondary lifting column to achieve secondary ejection of the housing. Both sides of the top of the bottom support base are connected to the inner side of the stamping groove via air guide frames to achieve cooling of the stamped housing.

[0007] Furthermore, the air-drawing frame includes traction air frames located on both sides of the bottom support base. Cooling fans are fixedly connected inside the outer sleeves of the traction air frames. Cooling arc frames are fixedly connected to both sides of the inside of the stamping groove. Multiple cooling holes are evenly opened on the outer side of the cooling arc frames.

[0008] Furthermore, the secondary lifting column includes a traction lifting frame that slides outside the main lifting column. The outer side of the traction lifting frame is fixedly connected to the secondary lifting column, and the outer side of the secondary lifting column is slidably connected to the inside of the bottom support base.

[0009] Furthermore, an anti-detachment plate is fixedly connected to the lower outer side of the main ejector column.

[0010] Furthermore, the interior of each of the secondary ejector columns is connected to the internal slot of the bottom support base via a limiting tension spring, in order to achieve the pullback limiting of the secondary ejector column.

[0011] Furthermore, two or more limiting rods are uniformly fixedly connected to the inner side of the mounting support frame. The bottom ends of the limiting rods are respectively fixedly connected to the top ends of the bottom support base, and the outer ends of the limiting rods are respectively slidably connected to the inside of the stamping plate.

[0012] Furthermore, both sides of the cooling arc frame are fixedly connected to diversion blocks, and the outer sides of the diversion blocks are respectively fixedly connected to the inner sides of the traction air frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the main ejector column is lifted to a certain height, and the traction lifting frame is moved to the upper side, so that multiple secondary ejector columns are ejected to the upper side simultaneously, thereby uniformly ejecting the outer shell to the outside, improving the demolding effect of the device, and ensuring the quality of the outer shell stamping.

[0015] 2. In this utility model, the external air is accelerated and drawn into the interior of the traction frame by the cooling fan, and then diverted into the interior of the cooling arc frame by the diversion connecting block, and discharged to the outside through the cooling holes, thereby cooling the outer shell, improving the cooling effect of the device, and reducing the risk of burns during demolding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a stamping device for processing a fan housing, comprising a bottom support base 1 for bottom support, a mounting support frame 2 fixedly connected to the top of the bottom support base 1, a stamping groove 7 formed in the middle of the top of the bottom support base 1, a hydraulic rod 4 fixedly connected to the middle of the bottom end of the mounting support frame 2, a stamping plate 5 fixedly connected to the output end of the hydraulic rod 4, an upper module 6 fixedly connected to the bottom end of the stamping plate 5, a main ejector column 13 slidably connected to the middle of the bottom support base 1, a threaded rod 19 rotatably connected to the middle of the inner side of the bottom support base 1, the external thread of the threaded rod 19 being threadedly connected to the inside of the main ejector column 13, a drive motor 11 fixedly connected to the bottom end of the inside of the bottom support base 1, the output end of the drive motor 11 being fixedly connected to the bottom end of the main ejector column 13, and the outside of the main ejector column 13 being connected to the inside of the bottom support base 1 via a secondary lifting column. The bottom support base 1 is connected to the inner side of the stamping groove 7 through the air guide frame on both sides to achieve the cooling of the shell after stamping. The secondary lifting column includes a traction lifting frame 18 that slides outside the main ejection column 13. The outer side of the traction lifting frame 18 is fixedly connected to the secondary ejection column 10. The outer side of the secondary ejection column 10 is slidably connected to the inside of the bottom support base 1. The lower side of the outer side of the main ejection column 13 is fixedly connected to the anti-detachment plate 12. The inside of the secondary ejection column 10 is connected to the inner groove of the bottom support base 1 through the limiting tension spring 17 to achieve the pull-back limit of the secondary ejection column 10. The inner side of the mounting support frame 2 is evenly fixedly connected to two or more limiting rods 3. The bottom end of the limiting rod 3 is fixedly connected to the top end of the bottom support base 1. The outer side of the limiting rod 3 is slidably connected to the inside of the stamping plate 5.

[0024] During the stamping operation, the material to be stamped is first precisely placed in the stamping groove 7. Then, the hydraulic rod 4 is activated to push the stamping plate 5 downward and press it tightly, so that the upper module 6 fits tightly against the material surface, and the stamping of the shell is successfully completed. When the shell needs to be demolded, the drive motor 11 is started to drive the threaded rod 19 to rotate. The external thread of the threaded rod 19 is tightly engaged with the internal thread of the main ejector column 13, thereby lifting the main ejector column 13 upward and applying external force to the shell. At this time, the anti-detachment plate 12 touches the traction lifting frame 18, which simultaneously causes multiple secondary ejector columns 10 to be ejected upward, realizing the secondary ejection of the shell, which significantly improves the working effect of the demolding device.

[0025] Reference Figure 2 and Figure 4 The air duct frame includes traction air duct frames 8 located on both sides of the bottom support base 1. Cooling fans 9 are fixedly connected inside the outer sleeve of the traction air duct frame 8. Cooling arc frames 15 are fixedly connected to both sides of the inside of the stamping groove 7. Multiple cooling holes 14 are evenly opened on the outer side of the cooling arc frame 15. Diversion connecting blocks 16 are fixedly connected to both sides of the cooling arc frame 15. The outer side of the diversion connecting blocks 16 is fixedly connected to the inner side of the traction air duct frame 8 respectively.

[0026] After the stamping process is successfully completed, the cooling fans 9 on both sides are immediately activated. They work together to accelerate the flow of external air into the depth of the traction air frame 8. Through the precise guidance of the diversion connecting block 16, the airflow in the traction air frame 8 is evenly distributed into the interior of the cooling arc frame 15. Subsequently, the airflow passes through the fine cooling holes 14 on the surface of the cooling arc frame 15 and is released to the outside, directly touching the bottom of the shell that has just been stamped. This process effectively achieves rapid cooling of the shell, significantly improves the performance of the cooling device, and greatly reduces the risk of burns that may occur during the demolding process.

[0027] Working principle: The material to be stamped is placed inside the stamping groove 7. At this time, the hydraulic rod 4 is activated to press the stamping plate 5 downward. The upper module 6 contacts the material to perform the stamping of the outer shell. After the stamping is completed, the cooling fans 9 on both sides are activated to accelerate the external air into the traction air frame 8. The airflow transmitted from the traction air frame 8 is then diverted into the cooling arc frame 15 through the diversion block 16 and discharged outward through the cooling holes 14 on the surface, contacting the bottom side of the stamped outer shell to cool it down. After cooling, the outer shell is pushed outward. At this time, the drive motor 11 is activated to rotate the threaded rod 19. The external thread of the threaded rod 19 contacts the inner side of the main ejector column 13, thus pushing the main ejector column 13 upward and exerting a force on the outer shell outward. When the anti-detachment plate 12 contacts the traction lifting frame 18, multiple secondary ejector columns 10 are pushed upward simultaneously, thus performing a second ejection of the outer shell and improving the demolding effect of the device.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
