[0002] The fan bottom plate bending device is a device specially used to bend the fan bottom plate material (usually metal plate, such as steel plate) according to a specific angle and shape. Its purpose is to make the fan bottom plate meet the overall structural design requirements of the fan and provide a suitable foundation for the installation of other parts of the fan. It is widely used in various fan manufacturing industries, including industrial ventilators, air conditioning fans, fire fighting fans, etc. For example; Four mounting gaskets are reserved at the four corners of the existing fan base plate before leaving the factory. However, the mounting gaskets at the four corners of the fan base plate need to be bent to facilitate subsequent staff to install the fan base plate on the fan. The bending angle of the mounting gaskets has strict requirements. After the bending is completed, the fan top plate and the clamp are in a clamping state. The fan base plate after processing needs to be removed. However, due to the influence of the clamping force, the operator needs to apply a pulling force when removing the fan base plate, which can easily cause the fan top plate to deform due to excessive pressure, and affect the work progress and efficiency.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] See also Figure 1 - Fig.11 , a fan bottom plate bending device shown in the figure includes a frame 1, a fan bottom plate body 2 is arranged on the frame 1, and also includes a support module 3 fixed on the frame 1, and a plurality of anti-skid pads 58 are fixed on the frame 1. By adding the anti-skid pads 58, the stability of the frame 1 during use can be effectively ensured to avoid the situation where the frame 1 shakes due to insufficient stability, and the support module 3 is used to support the fan bottom plate body 2, and a bending unit 4 adapted to the fan bottom plate body 2 is arranged on the frame 1, and the bending unit 4 is used to bend the fan bottom plate body 2 at the installation gasket, and a discharge mechanism 5 is arranged on the frame 1, and the discharge mechanism 5 is used to separate and discharge the fan bottom plate body 2; In this solution, by placing the fan base plate body 2 on the support module 3, the support module 3 forms a support and positioning for the fan base plate body 2. After the positioning of the fan base plate body 2 is completed, the bending unit 4 performs bending processing on the installation gasket position of the fan base plate body 2, which can accurately and efficiently complete the bending processing work on the installation gasket of the fan base plate body 2. The unloading mechanism 5 separates the fan base plate body 2 and the support module 3 after the bending processing, so as to achieve the purpose of quickly unloading the fan base plate body 2, effectively avoiding the deformation of the fan base plate body 2 due to manual pulling when taking out the material after the bending processing, and effectively providing a guarantee for the product qualification rate of the fan base plate body 2.

[0021] Specifically, the support module 3 includes a plurality of support frames a6 fixed on the frame body 1, and a positioning plate 7 is fixed on at least two support frames a6, and a groove 8 is opened on one of the positioning plates 7, and the groove 8 is used to pre-position the fan bottom plate body 2. At least two support frames b9 are fixed on the frame body 1, and the fan bottom plate body 2 is placed in the support frames b9 and the groove 8. A side bearing plate 10 is fixed on the frame body 1, and the side bearing plate 10 is in contact with the fan bottom plate body 2; It should be noted that the height of the support frame b9 is higher than the height of the support frame a6, which can accurately meet the size of the fan base plate body 2, ensuring that the fan base plate body 2 can be accurately placed on the support frame b9 and the support frame a6 to complete positioning, and through the setting of the side load-bearing plate 10, it is ensured that when the fan base plate body 2 is bent by the bending unit 4, the fan base plate body 2 is not offset due to thrust, and then the bending processing accuracy at the installation gasket of the fan base plate body 2 can be significantly improved, and the bending processing effect at the installation gasket of the fan base plate body 2 can be effectively improved; It should also be noted that the groove 8 provided on the positioning plate 7 is used to provide support space for the side of the fan base plate body 2, ensuring that the side of the fan base plate body 2 can be placed in a position between the positioning plate 7 and the side support plate, thereby ensuring the stability during the bending process of the fan base plate body 2 at the installation gasket, and effectively preventing the fan base plate body 2 from being displaced.

[0022] Further Figure 1 , Figure 3 , Figure 4 and Fig.11As shown, it is worth specifically explaining that the bending unit 4 includes a pad 11 fixed on the frame 1, a cylinder a12 is fixed on the pad 11, and a guide sleeve 13 is fixed on the pad 11, a movable block a14 slidably connected in the guide sleeve 13 is fixed on the output end of the cylinder a12, and a bending plate a15 is fixed on one side wall of the movable block a14, a cylinder b16 is fixed on the frame 1 through a mounting frame, a transmission plate 17 is fixed on the output end of the cylinder b16, and a positioning member 18 for matching the fan bottom plate body 2 is provided on the transmission plate 17, a guide rail 19 is fixed on the frame 1 through a support plate, and two movable blocks b20 are slidably connected on the guide rail 19, a bending plate b21 is fixed on the movable block b20, a guide column 22 is fixed on the movable block b20, and a guide groove 23 for sliding connection of the guide column 22 is provided on the transmission plate 17; It should be noted that a control switch 57 is provided on the frame 1, and the control switch 57 is electrically connected to the cylinder a12 and the cylinder b16, and the control switch 57 is used to uniformly control the synchronous driving of the two cylinders a12 and the cylinder b16, thereby ensuring the synchronization when bending the installation gaskets of the fan bottom plate body 2, and can simultaneously complete the bending processing of the four installation gaskets on the fan bottom plate body 2; The bending principle of the bending unit 4 on the mounting gasket of the fan base plate body 2 is as follows: by turning on the control switch 57, the two cylinders a12 and the cylinder b16 are driven synchronously, so that the movable block a14 and the transmission plate 17 are synchronously moved toward the fan base plate body 2, and the bending plate a15 is used to move the mounting gasket of the fan base plate body 2 closer to apply pressure, so that two of the mounting gaskets on the fan base plate body 2 are parallel to the fan base plate body 2, and when the movable block b20 is subjected to force, the guide column 22 is used to slide in the guide groove 23, and then the movable block b20 is subjected to force and then translates along the guide rail 19. At this time, the two movable blocks b20 move away from each other, and the bending plate b21 applies pressure to the mounting gasket of the fan base plate body 2, so that the bending angles of the other two mounting gaskets of the fan base plate body 2 are at right angles to the fan base plate body 2.

[0023] Further Figure 1 , Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, it is worth specifically explaining that the unloading mechanism 5 includes a bracket 31 fixed on the frame body 1, an active electric push rod 32 is fixed on the bracket 31, a channel 33 for the active electric push rod 32 to pass through is opened on the frame body 1, a mounting sleeve 34 is rotatably connected at the output end of the active electric push rod 32, a limiting member 35 for limiting the mounting sleeve 34 is provided on the active electric push rod 32, a rod body 36 is slidably penetrated in the mounting sleeve 34, an air flow nozzle 37 is fixed on the rod body 36, a butt joint 38 is commonly fixed between the two air flow nozzles 37, an air pump 39 is fixed on the frame body 1, the output end of the air pump 39 is fixed to the butt joint 38 through a connecting pipe a40, an air pressure tank 41 is fixed on the frame body 1, a connecting pipe b42 connected to the input end of the air pump 39 and the air pressure tank 41 is fixed, and an angle adjustment member 43 adapted to the rod body 36 is provided on the frame body 1; Specifically, the bottom horizontal plane of the bracket 31 is higher than the bottom horizontal plane of the frame 1, which can prevent the bracket 31 from contacting the ground, and the central axis of the active electric push rod 32 is arranged in a colinear manner with the central axis of the channel 33, ensuring that the active electric push rod 32 will not interfere with the frame 1 during the driving operation; It should be noted that the unloading assembly uses a pressurized airflow to unload the fan bottom plate body 2, and the pressurized airflow is sprayed toward the bottom position of the fan bottom plate body 2, and the airflow intensity can be adjusted according to the thickness of the fan bottom plate body 2, which can not only effectively improve the traditional unloading method, but also improve the unloading efficiency of the fan bottom plate body 2, and can effectively solve the deformation and damage of the fan bottom plate body 2 caused by manual pulling. Compared with the traditional manual unloading method that is prone to deformation and damage, the airflow unloading method used in this solution is more in line with the unloading work requirements of the fan bottom plate body 2; The unloading principle of the unloading assembly for the fan base plate body 2 after the bending is completed is as follows: the mounting sleeve 34 is driven by the electric push rod to move upward synchronously, and then the rod body 36 is driven to move synchronously until the air flow nozzle 37 is adjusted to a suitable height position, and the gas in the air pressure tank 41 is extracted and pressurized by the connecting pipe b42 through the connecting pipe a40, and the pressurized gas is delivered to the air flow nozzle 37, thereby spraying gas to the bottom of the fan base plate body 2 to achieve the effect of detaching from the support module 3.

[0024] In addition, the angle adjustment member 43 includes a mounting sleeve 51 rotatably connected to the frame body 1, the central axis of the mounting sleeve 51 is colinearly arranged with the central axis of the active electric push rod 32, a limiting groove 52 engaged with the rod body 36 is provided on the mounting sleeve 51, a servo motor 53 is fixed to the frame body 1, a rotating shaft 54 ​​is coaxially fixed to the output shaft of the servo motor 53, the rotating shaft 54 ​​is rotatably connected to the frame body 1, a spur gear 55 is fastened and sleeved on the rotating shaft 54, and a toothed ring 56 meshingly connected with the spur gear 55 is fixed to the mounting sleeve 51, at least two limiting blocks 59 are fixed to the mounting sleeve 51, the length of the limiting blocks 59 is greater than the tooth length of the toothed ring 56, and the addition of the limiting blocks 59 can prevent the mounting sleeve 51 from being disconnected from the spur gear 55 due to excessive rotation angle when rotating; It should be noted that when the injection angle position of the airflow nozzle 37 needs to be adjusted and changed, when the rod body 36 is engaged with the limit groove 52, the servo motor 53 is driven to make the rotating shaft 54 ​​rotate synchronously, driving the spur gear 55 to rotate synchronously, and utilizing the meshing transmission effect between the spur gear 55 and the toothed ring 56 to make the mounting sleeve 51 rotate after being subjected to force, thereby achieving the angle position of the airflow nozzle 37. After completing the angle adjustment work, the position is limited by the limit member 35, and the unloading mechanism 5 can unload the fan base plate body 2.

[0025] Further Figure 1 , Figure 8 and Fig. 9 As shown, it is worth specifically explaining that the limiting member 35 includes an additional plate a44 that is fastened and sleeved on the active electric push rod 32, at least two driven electric push rods 45 are fixed on the additional plate a44, an additional plate b46 is slidably sleeved on the active electric push rod 32, the output end of the driven electric push rod 45 is fixed to the additional plate b46, a spring c47 is sleeved on the active electric push rod 32, the two ends of the spring c47 are respectively fixed to the additional plate a44 and the additional plate b46, at least two limiting rods 48 are fixed on the additional plate b46, and a limiting disk 49 is fixed on the mounting sleeve 34, and a plurality of circumferentially distributed limiting holes 50 are opened on the limiting disk 49, and the limiting holes 50 are engaged and connected with the limiting rods 48; It should be noted that a slide groove is provided on the active electric push rod 32, and a slider slidably connected in the slide groove is fixed on the mounting plate b46, which can ensure that the mounting plate b46 always moves in the vertical up and down direction to avoid shaking or displacement when adjusting the position of the mounting plate b46; Specifically, the two driven electric push rods 45 are both located inside the channel 33, which can prevent the two driven electric push rods 45 from interfering with the frame 1 when moving up and down, and the number of the limiting holes 50 is greater than the number of the limiting rods 48, ensuring that the mounting sleeve 34 can be limited from all angles; The limiting member 35 releases the limiting principle of the mounting sleeve 34: when the limiting operation of the mounting sleeve 34 needs to be released, the two driven electric push rods 45 drive the mounting plate b46 to move downward after being subjected to force, thereby driving the limiting rod 48 to move synchronously until the limiting rod 48 is separated from the limiting hole 50. After the angle adjustment of the mounting sleeve 34 and the rod body 36 is completed, the driven electric push rod 45 drives the limiting rod 48 to move upward until the limiting rod 48 is engaged with the limiting hole 50, thereby completing the limiting purpose of the mounting sleeve 34.

[0026] Bending process for fan base plate installation gasket: First, the operator places the fan base plate body 2 on the support module 3 and ensures that the fan base plate body 2 is placed stably; Secondly, the installation gaskets at the four corners of the fan base plate body 2 are bent by the bending unit 4. After the bending process is completed, the bending unit 4 is reset to the initial position, and the fan base plate body 2 after bending is removed by the unloading mechanism 5. When the airflow injection angle needs to be adjusted, the angle adjustment member 43 and the limit member 35 are driven in cooperation to achieve the ability to spray strong airflow at different positions at the bottom of the fan base plate body 2 for unloading. Example

[0027] See also Figure 5 - Fig.11 , this embodiment further explains the first embodiment, and its difference lies in that the stability of the fan bottom plate body 2 when the installation gasket is bent is optimized, the positioning member 18 includes a mounting block 24 fixed on the movable block a14, a connecting rod 25 is slidably penetrated on the movable block a14, a positioning plate 7 abutting against the fan bottom plate body 2 is fixed on the connecting rod 25, a spring a26 is fixed between the connecting rod 25 and the mounting block 24, a mounting box 27 is fixed on the transmission plate 17, at least two connecting rods 28 are slidably penetrated in the mounting box 27, a positioning strip 29 abutting against the fan bottom plate body 2 is fixed on the connecting rod 28, a spring b30 is sleeved on the connecting rod 28, and the other end of the spring b30 is fixed to the inner wall of the mounting box 27; It should be noted that when the bending mechanism bends the fan base plate body 2 installing gasket, it can ensure that the two positioning plates 7 and the positioning strips 29 are in a fit state with the side edges of the fan base plate body 2, thereby forming pressures in two opposite directions, thereby ensuring that the fan base plate body 2 is in a highly stable state during the bending process, preventing displacement or shaking when bending the fan base plate body 2 installing gasket, wherein the elastic effect that the spring a26 and the spring b30 can provide ensures that the fan base plate body 2 remains in a stable state. Example

[0028] See also Fig.10 This embodiment further illustrates other embodiments, and the difference lies in that the unloading effect of the unloading mechanism 5 on the fan bottom plate body 2 is optimized.

[0029] Specifically, at least two rubber sleeves 60 are fixed on the rod body 36, the airflow nozzle 37 is located inside the rubber sleeve 60, and a soft rubber ring 61 is fixed on the top surface of the rubber sleeve 60, and the rubber sleeve 60 is located directly below the fan bottom plate body 2; It should be noted that, by using the active electric push rod 32 to fit the rubber sleeve 60 and the soft rubber ring 61 with the bottom surface of the fan base plate body 2, the airflow unloading effect of the airflow nozzle 37 can be maximized, avoiding the failure to achieve the expected effect when unloading the fan base plate body 2 due to insufficient air pressure, and further improving the airflow unloading effect of the fan base plate body 2.

They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
