Description

Technical Field

[0001] The utility model relates to the technical field of ceiling fan punching, and more specifically to a punching device for industrial ceiling fans. Background Art

[0002] Industrial ceiling fans are large hanging fans used in industrial environments. They are usually designed to provide strong air circulation and cooling effects in large spaces such as factories, warehouses, workshops, gymnasiums, supermarkets, etc. Since the blades of industrial ceiling fans need to be connected to the drive motor, industrial ceiling fan punching equipment is a device used to punch holes on the blades of industrial ceiling fans so that the blades can be connected to the motor through bolts.

[0003] The Chinese patent announcement number CN220049666U discloses sheet metal punching equipment. When punching, the punching component cooperates with the groove one and the support column gap, and the bottom end of the punch of the punching component is an inwardly concave inclined surface, the bottom end of the punch is a cutting edge, and the punch angle is 15 to 30 degrees, so that the cutting force generated by cutting the sheet metal is concentrated on the bottom edge line of the punch cutting edge, so that the cutting force is more concentrated at the cutting edge, the cross-sectional area of ​​the pressure plate is smaller than the cross-sectional area of ​​the workpiece groove, the power component one first drives the pressure plate to press the workpiece, and the force of the pressure plate on the workpiece is between the ejection force and the blanking force, so that the pressure plate compacts the area near the cutting area, and at the same time the support column provides an upward support force to the workpiece, and the power component two drives the punch downward to punch holes, so that the punching work is successfully completed on the frame.

[0004] When punching holes in the blades of an industrial ceiling fan, since the surface of the blades is curved, the device in the above scheme does not have a corresponding limit support mechanism. When punching holes in the curved blades, the punching head is pressed on the surface of the blades, and the force applied by the punching will be dispersed over a larger range, causing the punching area of ​​the blades to be subjected to more stress, making the blades prone to slight bending, shaking or displacement during the punching process, causing damage to the blades.

[0005] Therefore, it is necessary to provide a punching device for industrial ceiling fans to solve the above problems. Utility Model Content

[0006] The utility model provides a punching device for industrial ceiling fans, which can improve the problem in the related art that when the punching head is squeezed on the surface of the fan blade, the punching area of ​​the fan blade is subjected to more stress, making the fan blade prone to slight bending, shaking or displacement during the punching process, causing damage to the fan blade.

At the same time, the friction between the multiple abutment joints and the surface of the fan blades makes it difficult for the fan blades to be displaced when subjected to force, thereby improving the processing yield.

[0040] Industrial ceiling fans are large hanging fans used in industrial environments, providing strong air circulation and cooling effects in large spaces. Industrial ceiling fan punching equipment is a device used to punch holes on the blades of industrial ceiling fans.

[0041] When punching holes in the blades of an industrial ceiling fan, since the surface of the blade is curved, when the punching head is pressed against the surface of the blade, the force applied by the punching will be dispersed over a larger range, causing the punching area of ​​the blade to be subjected to more stress. Since the blades of a ceiling fan are usually thin, the blades are prone to slight bending, shaking or displacement during the punching process, causing damage to the blades.

[0042] Based on this, the problem existing in the related technology that when the punching head is squeezed on the surface of the fan blade, the punching area of ​​the fan blade is subjected to more stress, making the fan blade prone to slight bending, shaking or displacement during the punching process, causing damage to the fan blade can be improved.

[0043] See also Figure 1-Figure 5 A punching device for an industrial ceiling fan comprises a workbench 1 and an oil pipe 6. A hydraulic pump device 11 is arranged at the top of the workbench 1. Four slide bars 4 are fixedly connected to the top of the workbench 1. A fixed plate 10 is fixedly connected to the top of the slide bar 4. A hydraulic cylinder 5 is installed at the top of the fixed plate 10. A punching assembly 8 is arranged at the top of the workbench 1. Two limit assemblies 9 are arranged at the outer end of the punching assembly 8. The limit assembly 9 comprises an abutment rod 92. An abutment joint 94 is detachably connected to the top of the abutment rod 92. A first limit block 95 is fixedly connected to the bottom end of the abutment rod 92. A movable rod 96 is fixedly connected to the bottom end of the first limit block 95. A telescopic spring 93 is sleeved on the outer end of the movable rod 96.

[0044] The hydraulic cylinder 5 drives the hydraulic pump device 11 through the oil pipe 6. The output end of the hydraulic cylinder 5 is fixedly connected to the driving plate 7. A plurality of universal wheels 2 are installed at the bottom end of the workbench 1.

[0045] The bottom end of the driving disk 7 is fixedly connected with a movable plate 3 , and four sliding rods 4 all penetrate the movable plate 3 . The movable plate 3 is slidably connected to the sliding rods 4 , and the movable plate 3 is located below the fixed plate 10 .

[0046] Universal wheels 2 are installed on the four legs at the bottom of the workbench 1 in this scheme, so that the device can be easily moved. A hydraulic pump device 11 is installed on the top of the workbench 1. The hydraulic pump device 11 is mainly connected to the hydraulic cylinder 5 through the oil pipe 6 to transmit hydraulic energy and drive the hydraulic cylinder 5 to work. When the hydraulic pump device 11 starts to run, it will drive the piston, gears or blades and other working elements inside the pump, thereby increasing the pressure of the hydraulic oil, and push the hydraulic oil with increased pressure into the oil pipe 6. The oil pipe 6 transmits the high-pressure hydraulic oil to the hydraulic cylinder 5 connected to the hydraulic pump device 11. When the hydraulic oil enters the hydraulic cylinder 5, the piston will move under the action of the liquid pressure. The drive disk 7 is fixedly connected to the output end of the hydraulic cylinder 5 to drive the drive disk 7 to move up and down. Four sliding rods 4 are fixed at the four corners at the top of the workbench 1. The four slide bars 4 are slidably connected to the movable plate 3, so that the movable plate 3 can be driven to move up and down through the driving disk 7. A punching assembly 8 is arranged on the top of the workbench 1. The movable plate 3 moving downward can drive the punching assembly 8 to punch the fan blades. Two limit assemblies 9 are arranged on the top of the support plate 83. A plurality of abutment rods 92 distributed in an equidistant array extend from the through holes opened at the outer end of the shell 91. A rubber abutment joint 94 is installed on the top of each abutment rod 92. The fan blades are placed on the two limit assemblies 9. When the punching head device 85 is pressed down to punch the fan blades, the abutment rod 92 will adaptively move downward according to the curvature of the outer surface of the fan blades, so that the fan blades can be supported. At the same time, through the friction between the plurality of abutment joints 94 and the surface of the fan blades, the fan blades are not easily displaced when subjected to force, thereby improving the processing yield rate.

[0047] Optionally, in some embodiments, see Figure 2 and Figure 3 The punching assembly 8 includes a support plate 83 and a driving plate 81. The support plate 83 is fixedly installed on the top of the workbench 1. Four fixing rods 84 are fixedly connected to the top of the support plate 83. The multiple fixing rods 84 all penetrate the driving plate 81. The driving plate 81 is slidably connected to the fixing rods 84.

[0048] Two abutment blocks 82 are fixedly connected to the top of the driving plate 81, and the abutment blocks 82 abut against the bottom of the movable plate 3. Four rebounders 86 are fixedly connected between the driving plate 81 and the supporting plate 83. A punching head device 85 is fixedly connected to the bottom of the driving plate 81.

[0049] The support plate 83 mentioned above is fixed on the workbench 1, and four fixing rods 84 are fixed on the support plate 83. The driving plate 81 is slidably connected with the fixing rods 84, which is mainly used to increase the stability of the driving plate 81 when it moves up and down. Two abutment blocks 82 are fixed on the top of the driving plate 81, and a punching head device 85 for punching holes is fixed on the bottom end of the driving plate 81. When the movable plate 3 abuts against the abutment blocks 82, the driving plate 81 will drive the punching head device 85 to move downward to punch the fan blades placed on the two limit assemblies 9. At the same time, four rebounders 86 are fixed on the support plate 83. The rebounder 86 is mainly used to enable the driving plate 81 to move downward to punch holes. The rebounder 86 can push the driving plate 81 upward to reset it, which is convenient for taking the processed fan blades. The rebounder 86 is mainly composed of a spring and a damper, and can also play a role in buffering vibration.

[0050] Optionally, in some embodiments, see Figure 3-Figure 5 The limiting assembly 9 also includes a shell 91, the bottom end of the shell 91 is fixedly connected to the support plate 83, the inner wall of the shell 91 is fixedly connected to a partition 98, and the partition 98 and the outer end of the shell 91 are both provided with a plurality of through holes that are equidistantly distributed.

[0051] The bottom end of the movable rod 96 is fixedly connected to a second limit block 97 , the abutment joint 94 is made of rubber material, the top end of the abutment rod 92 passes through the side wall of the shell 91 and extends to the outside, the movable rod 96 passes through the partition 98 , and the partition 98 is located between the telescopic spring 93 and the second limit block 97 .

[0052] The limiting components 9 in the present scheme are provided with two, which are symmetrically fixed on the support plate 83, and there is a gap between the two limiting components 9, which is the position of the punching hole. A partition 98 is fixed inside the shell 91, and a plurality of through holes arranged in an equidistant array are provided on the partition 98 and the shell 91, wherein the abutment rod 92 is a through hole penetrating the shell 91, and the movable rod 96 is used to penetrate the through hole on the partition 98, and a detachable abutment joint 94 made of rubber is installed on the top of the abutment rod 92 to facilitate replacement after damage, and a telescopic spring 93 is sleeved on the movable rod 96, and the telescopic spring 93 mainly uses the telescopic force to reset the abutment rod 92 after moving, and the first limiting block 95 between the movable rod 96 and the abutment rod 92 is mainly used for The telescopic spring 93 is compressed in cooperation with the partition 98, and the second limit block 97 fixed at the bottom end of the movable rod 96 is used to limit the movable rod 96. When the fan blade is placed on the abutment joint 94 and the fan blade is punched by the punching head device 85, the fan blade is squeezed by the punching head device 85 and moves downward. At this time, the abutment rod 92 will adaptively descend according to the curvature of the fan blade. The descending distance of each abutment rod 92 is different. When the second limit block 97 abuts against the bottom of the shell 91, the abutment rod 92 will no longer move, so that the abutment rod 92 supports the fan blade through the abutment joint 94, so that it is not easy to deform when it is under pressure. At the same time, through the friction between multiple abutment joints 94 and the surface of the fan blade, the fan blade is not easy to shake or displace when subjected to force.

[0053] Working principle: When using the device, first, the blades need to be placed on the limit assembly 9 so that the area to be punched is located in the middle gap between the two limit assemblies 9. At this time, the hydraulic pump device 11 is started. When the hydraulic pump device 11 starts to operate, the high-pressure hydraulic oil will be transmitted to the hydraulic cylinder 5 through the oil pipe 6 to drive it, so that the driving disk 7 moves up and down, and the movable plate 3 is driven up and down by the driving disk 7. When the movable plate 3 abuts against the abutment block 82, the driving plate 81 will drive the punching head device 85 to move downward to punch the fan blades placed on the two limit assemblies 9. The fan blades will move downward due to the squeezing of the punching head device 85. At this time, the abutment rod 92 will move according to the curvature of the fan blade, so that the abutment rod 92 supports the fan blade through the abutment joint 94, which is not easy to deform. At the same time, through the friction between multiple abutment joints 94 and the surface of the fan blade, the fan blade is not easy to shake or displace when subjected to force.

[0054] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto.
