Description

Technical Field

[0001] The invention relates to the technical field of clutches, and in particular to a dry pneumatic clutch with a heat dissipation structure. Background Art

[0002] The punch press dry clutch is a key component used to transmit the power of the motor or engine to the punch press slider. It realizes the engagement and separation of power through friction to ensure that the punch press can accurately perform the punching operation. The punch press dry clutch is divided into electromagnetic clutch, pneumatic clutch and hydraulic clutch, among which the pneumatic clutch uses the pressure of compressed air to push or pull the pressure plate. It has the advantages of fast response speed, easy control and simple maintenance. It is widely used in the punch press field. When the pneumatic clutch applies pressure to the pressure plate, the friction plate is tightly pressed on the flywheel, and the friction between the two allows the power to be The force is transmitted from the flywheel to the pressure plate, which in turn drives the slider of the punch press to perform the punching action. During this process, the pressure plate is gradually fitted with the flywheel under the thrust of the gas until the friction between the two can overcome the load of the pressure plate, so that the pressure plate drives the punch press to perform the punching operation. During this process, if the friction between the two has not increased to overcome the load of the pressure plate, slippage will occur between the two. After long-term use, the friction loss of the friction plate on the pressure plate will cause the fit between the two to decrease, and then continuous slippage will occur, causing the temperature and friction loss of the friction plate to rise sharply, thereby shortening the service life of the friction plate.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] When the pneumatic clutch applies pressure to the pressure plate, the friction plate will be pressed tightly against the flywheel. At this time, the friction between the friction plate and the flywheel enables power to be transmitted from the flywheel to the pressure plate, thereby driving the slider of the punch press to perform the punching operation. However, in the process of the pressure plate and the flywheel fitting together, there may be a brief slippage between the two. As time goes by and with long-term use, the friction plate on the pressure plate gradually wears due to friction, resulting in a weakening of the fitting force between it and the flywheel, which will cause continuous slippage problems, not only causing the temperature of the friction plate to rise sharply, but also accelerating the wear of the friction plate, thereby significantly shortening its service life.

[0021] A dry pneumatic clutch with a heat dissipation structure, such as Figure 1-Figure 3 As shown, it includes: a main body 1; an outer cover 2, which is arranged on the main body 1; a pressure plate 3, which is sealingly and slidably connected in the outer cover 2, and the two cooperate to form a first closed cavity, the outer cover 2 is rotatably connected to the first fixing member 4, and a friction plate is arranged on the pressure plate 3; a first elastic element 5, which is arranged between the main body 1 and the pressure plate 3, the main body 1 is fixedly connected to the second fixing member 6, and the second fixing member 6 is used to drive the pressure plate 3 to rotate; an adjusting cylinder 7, which is fixedly connected to the outer cover 2, and the adjusting cylinder 7 is connected to the first closed cavity; a piston shaft 8, which is sealingly and slidably connected to the adjusting cylinder 7; a limiting ring 9, the first fixing member 4 is fixedly connected to the sliding rod, the limiting ring 9 is slidably connected to the sliding rod of the first fixing member 4, and the limiting ring 9 is limitedly and slidably connected to the piston shaft 8; a detection circulation component, which is arranged on the pressure plate 3, and is used to detect whether the friction plate on the pressure plate 3 and the second fixing member 6 slip according to the temperature.

[0022] In the above scheme, an air injection channel is provided in the middle of the outer cover 2 and is connected to an air injection device outside. The device is installed on the punch press. The first elastic element 5 is composed of a plurality of springs and support members, and is used to push the pressure plate 3 to reset. The friction plate on the pressure plate 3 is located on the side close to the second fixing member 6, and is used to increase the friction between the pressure plate 3 and the second fixing member 6. The pressure plate 3 is splined on the output shaft of the punch press. The first fixing member 4 is fixed to the outside of the punch press, that is, the first fixing member 4 is always in a stationary state. The second fixing member 6 is fixedly connected to the flywheel of the punch press, and is used to make the second fixing member 6 always in a Rotational state (the above is the basic common sense of installation of the punch clutch, which is common knowledge known to people in this field and will not be elaborated on), the number of adjusting cylinders 7 can be adjusted according to actual conditions, and the outside of the piston shaft 8 and the limiting ring 9 are provided with a wear-resistant coating, such as a chromium coating, to reduce the friction loss between the piston shaft 8 and the limiting ring 9, and by changing the volume of the first closed cavity and increasing the pressure of the gas in the first closed cavity, the friction plate on the pressure plate 3 is closely fitted with the second fixing part 6, thereby increasing the friction between the two, eliminating the slipping phenomenon of the two, and thus extending the service life of the friction plate on the pressure plate 3.

[0023] Specifically, Figure 3-Figure 7As shown, the detection circulation component includes: a sealing ring 201, which is sealingly rotatably connected to the pressure plate 3, and the two cooperate to form a second closed cavity; a circulation pump 202, a first fixing member 4 is fixedly connected to the connecting frame 10, and the circulation pump 202 is fixedly connected to the connecting frame 10; a first pipeline 2021, having two, which are respectively fixedly connected and connected to the output end and the input end of the circulation pump 202, and the two first pipelines 2021 are both fixedly connected to the sealing ring 201, and the two first pipelines 2021 are connected to the second closed cavity formed by the sealing ring 201 and the pressure plate 3; a detection component is arranged on any first pipeline 2021, and is used to detect the temperature of the pressure plate 3; a plurality of guide plates in an annular array are fixedly connected to the inner wall of the sealing ring 201, and the inclination directions and inclination angles of the plurality of guide plates relative to the sealing ring 201 are different.

[0024] In the above scheme, the second closed cavity formed by the pressure plate 3 and the sealing ring 201, the first pipe 2021 and the docking shell 203 are all filled with water to absorb the heat of the friction plate on the pressure plate 3. The connection between the first pipe 2021 and the sealing ring 201 is a flexible pipe, which is convenient for adapting to the position change of the pressure plate 3. The remaining positions are all hard pipes to prevent the first pipe 2021 from being wrapped around the outside of the pressure plate 3.

[0025] Specifically, Figure 3-Figure 7 As shown, the detection component includes: a docking shell 203, fixedly connected and connected to any one of the first pipes 2021; an elastic push rod 204, fixedly connected to the inside of the docking shell 203, and the telescopic end of the elastic push rod 204 passes through the docking shell 203; a heat dissipation component, arranged on the first pipe 2021, for dissipating the heat in the pressure plate 3; a pushing component, arranged on the connecting frame 10, for moving the limit ring 9.

[0026] In the above scheme, the fixed part of the elastic push rod 204 is filled with heated and expanded gas, which is used to drive its telescopic end to move according to the temperature of the water. The water absorbs the heat of the friction plate on the pressure plate 3 in the second closed cavity and circulates to the docking shell 203 to drive the telescopic end of the elastic push rod 204 to extend out, which is used to detect whether the friction plate on the pressure plate 3 and the second fixing member 6 are slipping according to the temperature of the pressure plate 3.

[0027] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, the pushing assembly includes: a screw 301, which is rotatably connected to the connecting frame 10, and the screw 301 is threadedly connected to the limiting ring 9; a driving gear 302, which is fixedly connected to the screw 301; a first rack rack 303, which is slidably connected to the connecting frame 10, and the first rack rack 303 is meshed with the driving gear 302; a driving assembly, which is arranged on the connecting frame 10, and is used to drive the first rack rack 303 to move.

[0028] In the above scheme, the screw 301 locks the limit ring 9 through its own thread. The materials of the limit ring 9 and the screw 301 are both high-strength steel, which has high structural strength and extends the service life of the screw 301. The length of the first rack 303 can at least drive the driving gear 302 to rotate more than 5 circles to ensure the descending distance of the limit ring 9. The limit ring 9 is driven by the rotation of the screw 301 to move the piston shaft 8 along the adjusting cylinder 7, thereby reducing the volume of the first closed cavity, increasing the friction between the friction plate on the pressure plate 3 and the second fixing member 6, and timely avoiding the slippage of the friction plate on the pressure plate 3 and the second fixing member 6.

[0029] Specifically, Figure 4 and Figure 5 As shown, the driving assembly includes: a pushing frame 304, which is slidably connected to the connecting frame 10, and the pushing frame 304 is fixedly connected to the first rack frame 303; a second elastic element 305, which is arranged between the connecting frame 10 and the pushing frame 304; a plurality of clamping blocks 306, and the plurality of clamping blocks 306 are staggered and fixedly connected to the pushing frame 304; a limiting assembly, which is arranged on the connecting frame 10, and is used to alternately block all the clamping blocks 306.

[0030] In the above scheme, the second elastic element 305 is a tension spring and is initially in a stretched state, which is used to drive the pushing frame 304 to slide along the connecting frame of the first fixing member 4. A plurality of clamping blocks 306 are staggeredly distributed on the front and rear sides of the pushing frame 304 in the vertical direction. The distance between two adjacent clamping blocks 306 is equal, and the distance is greater than or equal to twice the circumference of the dividing circle of the driving gear 302, ensuring that the driving gear 302 rotates more than one circle each time.

[0031] Specifically, Figure 5 and Figure 6 As shown, the limiting assembly includes: a second rack frame 401, which is slidably connected to the connecting frame 10; a limiting frame 402, which has two, is fixedly connected to the second rack frame 401, and the two limiting frames 402 are used to alternately limit the block 306; a transmission assembly, which is arranged on the connecting frame 10, and is used to move the pushing frame 304.

[0032] The second rack 401 is used to push the limit rack 402 to move. The limit rack 402 is provided with a groove. The extension distance of the telescopic end of the elastic push rod 204 is consistent with the width of the groove of the limit rack 402. The distance between two adjacent grooves of the limit rack 402 is the same as the width of the block 306. The two limit racks 402 respectively limit the plurality of blocks 306 on the front and rear sides of the pushing rack 304, and the grooves on the two limit racks 402 are alternately distributed, that is, only one limit rack 402 limits one block 306 at a time, and they operate alternately back and forth, so that the pushing rack 304 pushes the first rack 303 equidistantly, so that the first rack 303 drives the driving gear 302 to rotate a specific angle, and then the volume reduced by the first closed cavity each time is a constant value, ensuring that the fitting force between the friction plate on the pressure plate 3 and the second fixing member 6 remains stable, thereby extending the service life of the friction plate on the pressure plate 3.

[0033] Specifically, Figure 5 and Figure 6 As shown, the transmission assembly includes: a third rack 403, fixedly connected to the telescopic end of the elastic push rod 204; a one-way gear 404, arranged on the connecting frame 10, the third rack 403 is meshed with the one-way gear 404; a transmission gear 405, fixedly connected to the output end of the one-way gear 404, the transmission gear 405 is meshed with the second rack 401.

[0034] In the above scheme, when the telescopic end of the elastic push rod 204 extends out to drive the third rack rack 403 to move, the one-way gear 404 can drive the transmission gear 405 to rotate synchronously. When the telescopic end of the elastic push rod 204 drives the third rack rack 403 to reset, the one-way gear 404 cannot drive the transmission gear 405 to rotate synchronously, which is used to enable the transmission gear 405 to push the second rack rack 401 to move in one direction.

[0035] Working principle: During the use of the device, the first fixing member 4 is fixed to the outside of the punch press so that the first fixing member 4 cannot rotate, and then the second fixing member 6 is fixedly connected to the flywheel of the punch press, so that the flywheel of the punch press drives the second fixing member 6 and the main body 1 to always be in a rotating state, and the pressure plate 3 is splined to the driving shaft of the punch press. When the device needs to be used, the staff injects gas into the first closed cavity through the gas injection device, so that the gas in the first closed cavity pushes the pressure plate 3, and the pressure plate 3 compresses the first elastic element 5. At the same time, the friction plate on the pressure plate 3 is in contact with the second fixing member 6, and the second fixing member 6 drives the driving shaft of the punch press to rotate synchronously through the friction plate on the pressure plate 3, thereby completing the punching work of the punch press. When the punching work of the punch press is stopped, the gas in the first closed cavity is withdrawn, the first elastic element 5 is reset and the friction plate on the pressure plate 3 is pushed to separate from the second fixing member 6, and the second fixing member 6 cannot drive the driving shaft of the punch press to rotate through the friction plate on the pressure plate 3, and the cycle is repeated to complete the action of the punch press.

[0036] During the process of docking or separation of the friction plate on the pressure plate 3 and the second fixing member 6, due to the insufficient fitting force between the two, the friction plate on the pressure plate 3 and the second fixing member 6 may slip due to friction. After long-term use, it is very easy to cause the friction plate on the pressure plate 3 to be worn out due to friction, causing the friction plate on the pressure plate 3 to be unable to fit tightly against the second fixing member 6 locally, and then continuous slipping occurs, causing the friction plate on the pressure plate 3 to be rapidly worn out due to friction and generate a large amount of heat, which greatly shortens its service life. Therefore, when the punching machine starts to run, the circulation pump 202 is synchronously turned on, so that the circulation pump 202 drives the water in the first closed cavity to circulate along the first pipe 2021. When the water flows through the second closed cavity, it absorbs the heat of the friction plate on the pressure plate 3, and the water carries the heat into the docking shell 203. As the temperature gradually rises, the temperature of the expanding gas in the fixed part of the elastic push rod 204 rises synchronously, and the gas in the fixed part of the elastic push rod 204 expands due to the heat, and pushes the telescopic end of the elastic push rod 204 to slide outward along the docking shell 203.

[0037] When the telescopic end of the elastic push rod 204 slides outward along the docking shell 203, the telescopic end of the elastic push rod 204 drives the third rack 403 to move synchronously, and the third rack 403 drives the one-way gear 404 to rotate, and the one-way gear 404 drives the transmission gear 405 to rotate, so that the transmission gear 405 drives the two limiting frames 402 to slide through the second rack 401. At this time, the lower limiting frame 402 releases the limit on the adjacent block 306, and then the second elastic element 305 pulls the pushing frame 304 to slide along the connecting frame 10, until the block 306 above the pushing frame 304 contacts the upper limiting frame 402 and limits each other.

[0038] After the upper limiting frame 402 limits the blocking block 306, the pushing frame 304 stops sliding. During the sliding process of the pushing frame 304 along the connecting frame 10, the pushing frame 304 drives the first rack frame 303 to move synchronously, so that the first rack frame 303 drives the lead screw 301 to rotate through the driving gear 302, so that the lead screw 301 drives the limiting ring 9 to move downward. At this time, the limiting ring 9 drives the piston shaft 8 to move downward synchronously, compressing the gas in the first closed cavity, increasing the pressure of the gas in the first closed cavity, making the friction plate on the pressure plate 3 fit tightly with the second fixing part 6, increasing the friction between the two, avoiding the continuous operation of the slipping phenomenon, and thereby extending the service life of the friction plate on the pressure plate 3.

[0039] When there is no more slippage between the friction plate on the pressure plate 3 and the second fixing member 6, as the circulation pump 202 circulates, the temperature of the water in the first closed cavity gradually decreases. At this time, the temperature of the gas in the fixed part of the elastic push rod 204 decreases synchronously, and drives its telescopic end to reset. The telescopic end of the elastic push rod 204 drives the third rack 403 to reset. At this time, the third rack 403 cannot drive the transmission gear 405 to rotate through the one-way gear 404, and this continues until the telescopic end of the elastic push rod 204 is reset to the initial state. When continuous slippage occurs again, repeat the above steps.

[0040] In a further embodiment, Figure 1 , Figure 4 and Figure 7 As shown, the radiator 501 is fixedly connected to the connecting frame 10, the input end of the radiator 501 and the first pipe 2021 are fixedly connected to the output end of the radiator 501 and the docking shell 203 and are connected by a second pipe 5011; the cooling fan 502 is installed on the radiator 501; the adjustment component is arranged on the telescopic end of the elastic push rod 204, and is used to change the heat dissipation rate.

[0041] In the above scheme, the radiator 501 is a plate heat exchanger whose surface is processed into fins to increase the heat exchange area. It has a simple structure and low cost. The cooling fan 502 is an axial flow fan with low noise, easy installation and low energy consumption. It is used to release the heat of the friction plate on the pressure plate 3 from the radiator 501.

[0042] Specifically, Figure 7 As shown, the regulating component includes: two regulating valves 503, which are respectively arranged in the first pipeline 2021 and the second pipeline 5011, and the rotating ends of the regulating valves 503 are fixedly connected with regulating gears 504; a fourth rack rack 505, which is fixedly connected to the third rack rack 403, and the two regulating gears 504 are meshed with the fourth rack rack 505.

[0043] In the above scheme, in the initial state, the flow aperture of the regulating valve 503 on the first pipe 2021 is larger than the flow aperture of the regulating valve 503 on the second pipe 5011, which is used to prevent most of the water from dissipating heat through the radiator 501, thereby rapidly increasing the temperature of the gas in the fixed part of the elastic push rod 204. The two regulating valves 503 have opposite adjustment directions, which are used to simultaneously reduce the flow aperture of the first pipe 2021 while increasing the flow aperture of the second pipe 5011, so that most of the water flows through the radiator 501 and rapidly dissipates the heat generated by slipping.

[0044] When the device starts to operate, the circulation pump 202 and the cooling fan 502 are turned on synchronously. When the circulation pump 202 drives the water to circulate along the first closed cavity and the first pipe 2021, part of the water will enter the radiator 501 along the second pipe 5011. At this time, the cooling fan 502 will drive the external air to flow through the radiator 501. The airflow will absorb the heat of the water in the radiator 501 to prevent the heat from accumulating on the pressure plate 3, causing its temperature to rise and shortening its service life. When the pressure plate 3 and the second fixing member 6 slip, the gas in the fixed part of the elastic push rod 204 expands due to the heat, so that the telescopic end of the elastic push rod 204 drives the fourth rack 505 to move outward, and the fourth rack 505 drives the two adjusting gears 504 to rotate synchronously. The adjusting gear 504 drives the rotating end of the adjacent regulating valve 503 to rotate synchronously, thereby reducing the flow aperture of the first pipe 2021 and increasing the flow aperture of the second pipe 5011. Most of the water flows through the second pipe 5011 into the radiator 501, so that the heat generated by the slippage of the pressure plate 3 and the second fixing member 6 is quickly discharged, thereby preventing the heat of the pressure plate 3 from being unable to be discharged in time, thereby shortening the service life of the pressure plate 3, and so on until the heat is gradually discharged. As the temperature decreases, the telescopic end of the elastic push rod 204 is gradually reset, thereby causing the fourth rack 505 to drive the two adjusting gears 504 to reset and rotate, thereby restoring the initial flow aperture of the first pipe 2021 and the second pipe 5011. When slippage occurs again, the above steps are repeated.

[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
