Description

Technical Field

[0001] This invention relates to the field of hot forging press technology, specifically a hot forging press for a multi-layer friction plate structure clutch. Background Technology

[0002] Early hot forging presses were similar to flat forging presses in terms of rigidity and basic component composition, featuring a trunk-guided slide and a rigid connection for support. With continuous technological advancements, hot forging presses underwent numerous improvements. For example, in the early 1940s, the clutch was moved to the eccentric shaft, and a safety friction clutch was installed on the flywheel. From the 1960s onwards, to improve the precision of forgings, productivity, and the reliability of press operation, hot forging presses entered a diversified development phase. From the 1970s onwards, the fundamental characteristics of hot forging press development were large-scale and automation. Automatic hot forging lines and multi-station automatic hot forging presses, with hot forging presses as the main unit, developed rapidly. The application of microcomputers in hot forging press control provided a guarantee for the automation development of hot forging presses. Hot forging presses are widely used in the automotive, tractor, internal combustion engine, shipbuilding, aviation, mining machinery, petroleum machinery, and hardware tool manufacturing industries. It is mainly used for batch forging and finishing of ferrous and non-ferrous metals. The forged parts have high precision, high material utilization, high productivity, and are easy to automate.

[0003] For example, Chinese patent CN216199999U discloses an air-cooled and water-cooled brake for a hot forging press, including a brake seat, an internal gear ring, a water-cooled external gear friction plate, a cylinder, and an air-cooling assembly. The cylinder, internal gear ring, and brake seat are connected by bolts. The water-cooled external gear friction plate is located inside the internal gear ring and meshes with it. The interior of the water-cooled external gear friction plate has a water tank for flowing coolant, and the side wall of the water-cooled external gear friction plate has an inlet and an outlet communicating with the water tank. The internal gear ring has multiple windows, and the air-cooling assembly is located on the outside of the internal gear ring for blowing air through the windows. This air-cooled and water-cooled brake for a hot forging press can remove the heat from the friction plate through the flow of water and remove the hot air inside the brake through the accelerated flow of air, greatly improving the working performance of the brake friction plate, extending the service life of the brake, and ensuring the safe and reliable operation of the hot forging press.

[0004] For example, Chinese patent CN206943269U discloses a multi-layer friction pad brake, including a flywheel and friction pads mounted on the flywheel. It also includes a support frame for connection to a vehicle body, brake pads on the bottom surface of the support frame, a lead screw seat fixed to the side of the support frame, a lead screw on the lead screw seat, and a drive motor connected to the lead screw. The number of friction pads is at least two, and the number of brake pads is one more than the number of friction pads. The brake pads and friction pads are spaced apart, with the outermost brake pad located on the outer surface of the outermost friction pad. A return spring is fixed between adjacent brake pads, and the end of the lead screw presses against the outermost brake pad, with a return spring fixed between the brake pads. This invention has a reasonable structural design, using multiple friction pads in conjunction with multiple brake pads. During use, the braking operation is completed by the mutual squeezing and friction between the multiple friction pads and the brake pads, thereby greatly improving the reliability and stability of braking. It is highly applicable and practical.

[0005] However, for a hot forging press with an air-cooled and water-cooled brake, although the press uses water flow to remove heat from the friction plates and airflow to remove hot air from the internal space of the brake, greatly improving the working performance of the friction plates, extending the service life of the brake, and ensuring the safe and reliable operation of the hot forging press, it cannot easily adjust the transmission torque and action time of the clutch by adjusting the clamping force of the friction plates. For a multi-layer friction plate brake, multiple friction plates are used in conjunction with multiple brake plates. During use, the braking operation is completed by the mutual squeezing and friction between the multiple friction plates and the brake plates, greatly improving the reliability and stability of the brake, and offering strong applicability and practicality. However, the overall squeezing and friction of multiple friction plates is not individual squeezing, therefore, it is not possible to precisely control the clamping force of the friction plates, and thus cannot precisely control and adjust the transmission torque and action time of the clutch. Therefore, a hot forging press with a multi-layer friction plate clutch structure is proposed. Summary of the Invention

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a hot forging press for a multi-layer friction plate structure clutch, which has the following beneficial effects:

[0023] 1. The hot forging press of the multi-layer friction plate structure clutch has a clutch outer box set at the upper end of the hot forging press, and a rotating shaft is set inside. Three friction plates are fixedly connected on the rotating shaft. There is a large gap between the three friction plates. The gap between the multi-layer friction plates is conducive to heat dissipation, reduces the temperature of the friction surface, and extends the service life of the friction plates.

[0024] 2. The hot forging press of this multi-layer friction plate structure clutch has a tightening device at the position of each of the three friction plates, and a hand crank is provided on the outside of the clutch outer box. A rotating rod is movably connected to the corresponding position inside. The two are fixedly connected and used for manual adjustment. By manually adjusting, the adjustment device on the rotating rod is linked with the tightening device, so that the transmission torque and action time of the clutch can be easily adjusted by adjusting the clamping force of the friction plates.

[0025] 3. The hot forging press of this multi-layer friction plate structure clutch uses a tightening device including a fixed seat, a support plate, a limit plate, a movable rod, a clamping rod, and an adjusting rod. By moving between two adjusting rods, one end of the movable rod moves inward and outward, so that the other end of the movable rod can be brought together or dispersed by the clamping rod relative to the clamping block, thereby adjusting the clamping force of the friction plate and further adjusting the transmission torque of the clutch.

[0026] 4. The hot forging press of this multi-layer friction plate structure clutch drives the rotating rod to rotate the connecting gear above it by rotating the hand crank. Through the meshing of the connecting gear and the second bevel gear, the clamping device clamps the friction plate.

[0027] 5. The hot forging press of the multi-layer friction plate structure clutch includes a moving sleeve, a moving groove and a second moving groove through the adjustment device. By adjusting the moving column at the outer end of the clutch outer box in the second moving groove, the moving sleeve is driven to move relative to the connecting gear, thereby conveniently controlling the linkage between the connecting gear and several tightening devices.

[0028] 6. The hot forging press of this multi-layer friction plate structure clutch can control the linkage of one or more tightening devices through the adjustment device, thereby achieving precise control and adjustment of the clamping force of the friction plates.

[0029] 7. The hot forging press of the multi-layer friction plate structure clutch has a toothed groove between the upper and lower adjusting rods, and the two adjusting rods are connected by gears and a rotating column, so that the two adjusting rods can form relative motion. The bevel gear at one end of the rotating column meshes perpendicularly with the second bevel gear on the connecting seat to form a transmission mechanism, so that the operation of the hand crank can accurately control the clamping force of the friction plate.

[0030] 8. The hot forging press of this multi-layer friction plate structure clutch has three concave second moving grooves that correspond to each other. The operation of the outer periphery of the clutch in the three second moving grooves can affect the operation in the moving groove inside the clutch outer box, providing flexible movement and fixation for the movement of the connecting gear.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-11 A hot forging press for a multi-layer friction plate clutch includes a hot forging press 1, a clutch outer box 2, a rotating shaft 3, friction plates 4, a motor 5, a hand crank 6, and a rotating rod 7. The upper side of the hot forging press 1 is fixedly connected to the clutch outer box 2, and the rotating shaft 3 is movably inserted into the upper end of the hot forging press 1 corresponding to the position of the clutch outer box 2. The rotating shaft 3 passes through the clutch outer box 2 and extends into it. Three friction plates 4 are fixedly connected to the rotating shaft 3 inside the clutch outer box 2. The motor 5 is fixedly connected to the outer side of the clutch outer box 2, and one end of the rotating shaft 3 is fixedly connected to the output end of the motor 5. The hand crank 6 is movably inserted into the outer side of the clutch outer box 2 corresponding to the position of the hand crank 6, and the rotating rod 7 is movably connected to the inner side of the clutch outer box 2 corresponding to the position of the hand crank 6. The rotating rod 7 is fixedly connected to the hand crank 6. The press is characterized by further comprising:

[0045] Clamping blocks 8 are provided on both sides of the three friction plates 4, and three tightening devices are provided on the side ends of the three friction plates 4 respectively. The three tightening devices are respectively set together with the clamping blocks 8 on both sides of the three friction plates 4. The tightening devices are used to gather the clamping blocks 8 towards the middle and clamp the friction plates 4. By adjusting the clamping force of the friction plates 4, the transmission torque of the clutch can be adjusted.

[0046] Three connecting gears 9 are provided on the rotating rod 7, and the three connecting gears 9 correspond to three tightening devices respectively. An adjusting device is provided between the rotating rod 7 and the three connecting gears 9. This adjusting device is used to adjust the movement of the three connecting gears 9, so as to control the clamping force of one or more tightening devices on the friction plate 4. The motor 5 on the hot die forging press 1 drives the rotating shaft 3 inside the clutch outer box 2 to rotate, thereby driving the forging according to the rotation of the rotating shaft 3. The rotating shaft 3 is located inside the clutch outer box 2 and contains three friction plates 4. Each of the three friction plates 4 is equipped with a clamping device at both ends. The clamping block 8 is tightened by three tightening devices. By adjusting the clamping force of the friction plate 4 through the clamping block 8, the transmission torque and action time of the clutch can be easily adjusted. However, a single friction plate 4 is usually insufficient to effectively control the clamping force. This application uses three friction plates 4 and a hand crank 6 to rotate the rotating rod 7, which drives the connecting gear 9 on the rotating rod 7 to link with the tightening device. Thus, the adjustment device on the rotating rod 7 can adjust whether the three connecting gears 9 are used individually or in combination to link with the tightening device, thereby better controlling and adjusting the clamping force of the friction plate 4.

[0047] The three tightening devices include a fixed seat 10, a support plate 11, a limiting plate 12, a movable rod 13, a clamping rod 14, and an adjusting rod 15. The fixed seat 10 is fixedly connected to the inner wall of the clutch outer box 2, and two support plates 11 are fixedly connected to the upper two sides of the fixed seat 10. A limiting plate 12 is fixedly connected to one end of the upper end of the fixed seat 10 corresponding to the outer side of the two support plates 11. A movable rod 13 is provided at the outer end of the limiting plate 12, and a clamping rod 14 is provided at the upper end of the movable rod 13. The clamping rod 14 is movably inserted into the upper end of the support plate 11, and a clamping block 8 is fixedly connected to one end of the two clamping rods 14 that are close to each other. An adjusting rod 15 is provided at the lower end of the movable rod 13, and the adjusting rod 15 extends into the interior of the fixed seat 10.

[0048] The outer end of the limiting plate 12 is provided with a limiting groove 16, and the limiting groove 16 and the middle position of the movable rod 13 are movably connected together by a movable column.

[0049] The upper end of the movable rod 13 is provided with a groove 17, and the groove 17 is movably connected to one end of the clamping rod 14 through a connecting post.

[0050] The lower end of the movable rod 13 is provided with a second groove 18, and the second groove 18 is movably connected to one end of the adjusting rod 15 through a connecting post. The lower end of the movable rod 13 at the other end is fixedly connected to a connecting plate 19, and the lower end of the connecting plate 19 is provided with a third groove 20, and the third groove 20 is movably connected to one end of the adjusting rod 15 through a connecting post. The two adjusting rods 15 are arranged in an up-and-down stacked manner.

[0051] A toothed groove 21 is provided at one end of the two adjusting rods 15 that are approaching each other, and a gear 22 is provided between the two adjusting rods 15. The gear 22 and the toothed groove 21 are meshed together. A rotating column is fixedly connected to the middle position of the gear 22, and the rotating column is movably connected to the inner wall of the fixed base 10. One end of the rotating column extends to the outer wall of the fixed base 10 and is fixedly connected to a bevel gear 23. A connecting seat 24 is fixedly connected to the side wall of the fixed base 10 corresponding to the side end of the bevel gear 23. One end of the movable rod 15 is movably connected to a second bevel gear 25, which meshes perpendicularly with a bevel gear 23. The connecting gear 9 drives the outer end of the second bevel gear 25 to rotate, thereby causing the perpendicularly meshing bevel gear 23 to rotate. After the bevel gear 23 rotates, it drives the internal gear 22 to rotate via a rotating column. Because one end of the adjusting rod 15 is equipped with a connecting plate 19, while the other end does not, there is a vertical difference in the height of the adjusting rod 15 at the lower end of the movable rod 13. Gears 22 exist between the upper and lower adjusting rods 15. The upper and lower adjusting rods 15 have toothed grooves 21, and the rotation of the gears 22 drives the upper and lower adjusting rods 15 to move outwards to both sides. This movement of the two adjusting rods 15 causes the movable rod 13 to rotate at its base point within the limiting groove 16 of the limiting plate 12. The lower end moves outwards, causing the upper end of the movable rod 13 to move inwards. The upper end of the movable rod 13 then drives the clamping rod 14 to press inwards. Since the clamping rod 14 is located on the support plate... In step 11, left and right limit movements are made. The upper end of the movable rod 13 is connected to the clamping rod 14 via the groove 17. When the movable rod 13 tilts inward, the clamping rod 14 is prevented from interfering with the movement of the movable rod 13. The groove 17 allows the clamping rod 14 to move, thus smoothly pressing the clamping rod 14 towards the center. The two clamping rods 14 are used to press the friction plate 4 through the clamping block 8, causing the friction plate 4 to drive the rotating shaft 3 to change the transmitted torque.

[0052] The adjusting device includes a movable sleeve 26, a movable groove 27, and a second movable groove 28. The rotating rod 7 has three movable grooves 27 respectively corresponding to the positions of the three connecting gears 9, and the movable sleeve 26 is movably sleeved on the rotating rod 7 corresponding to the positions of the three movable grooves 27. The three movable sleeves 26 are fixedly connected to the three connecting gears 9 respectively, and the rotating rod 9 has three second movable grooves 28 corresponding to the position of the outer end of the clutch outer box 2.

[0053] The three movable slots 27 and the three second movable slots 28 are respectively arranged in a corresponding manner, and the three second movable slots 28 are arranged in a concave shape.

[0054] The inner walls of the three movable sleeves 26 are fixedly connected with connecting blocks 29, and the connecting blocks 29 are movably connected to the movable grooves 27. The connecting blocks 29 extend into the interior of the rotating rod 9, and the end of the connecting blocks 29 located inside the rotating rod 9 is movably connected to a movable column 30, which is L-shaped.

[0055] The three connecting gears 9 can mesh with the three second bevel gears 25 by moving. When it is necessary to change the clamping force by clamping the friction plate 4, a single clamping block 8 cannot achieve precise control. Therefore, by rotating the hand crank 6, the rotating rod 7 can drive the connecting gears 9 to mesh with the second bevel gears 25 in the tightening device, causing the second bevel gears 25 to rotate. This, in turn, drives the bevel gear 23 to rotate the gear 22 in the fixed seat 10. Since each of the three friction plates 4 is equipped with a corresponding tightening device, three second moving grooves 28 are provided at one end of the rotating rod 7 outside the clutch outer box 2. By moving the moving column 30 in the second moving grooves 28, it drives the connecting block 29 on the moving sleeve 26 to move in the moving grooves 28. The moving sleeve 26 moves the connecting gear 9, causing it to mesh with the second bevel gear 25. If multiple tightening devices are not desired to clamp the friction plate 4, the other two moving columns 30 are moved backward and engaged in the concave second moving groove 28 to complete the fixation. This causes the moving sleeve 26 to disengage the connecting gear 9 from the second bevel gear 25, thus achieving clamping by a single tightening device. When precise control of the clamping force of the friction plate 4 is required, the moving column 30 can be moved forward to drive the moving sleeve 26 to engage the connecting gear 9 with the other second bevel gears 25, completing the meshing of multiple connecting gears 9 with the second bevel gears 25, thereby completing the clamping of the friction plate 4 by multiple tightening devices and precisely controlling the clamping force of the friction plate 4.

[0056] Working principle: The motor 5 on the hot forging press 1 drives the rotating shaft 3 inside the clutch outer box 2 to rotate, thereby driving the forging process. The rotating shaft 3 is located inside the clutch outer box 2 and contains three friction plates 4. Each of the three friction plates 4 has a clamping block 8 at both ends. The clamping blocks 8 are tightened by three tightening devices. The clamping force of the friction plates 4 can be adjusted by the clamping blocks 8, which can conveniently adjust the transmission torque and action time of the clutch. However, a single friction plate 4 is usually not enough to control the clamping force. This application uses three friction plates 4 and a hand crank 6 to rotate the rotating rod 7, which drives the connecting gear 9 on the rotating rod 7 to link with the tightening device. The adjustment device on the rotating rod 7 can adjust whether the three connecting gears 9 are used individually or in combination to link with the tightening device, thereby better controlling and adjusting the clamping force of the friction plates 4.

[0057] When the clamping force needs to be changed by clamping the friction plate 4, a single clamping block 8 cannot provide precise control. Therefore, by rotating the hand crank 6, the rotating rod 7 drives the connecting gear 9 to mesh with the second bevel gear 25 in the tightening device, causing the second bevel gear 25 to rotate. This, in turn, drives the bevel gear 23 to rotate the gear 22 in the fixed seat 10. Since each of the three friction plates 4 has a corresponding tightening device, three second moving grooves 28 are provided at one end of the rotating rod 7 outside the clutch outer box 2. By moving the moving column 30 in the second moving grooves 28, it drives the connecting block 29 on the moving sleeve 26 to move in the moving groove 27, causing the moving sleeve 26 to move. The moving connecting gear 9 moves to engage with the second bevel gear 25. If multiple tightening devices are not desired to clamp the friction plate 4, the other two moving columns 30 are moved backward and engaged in the concave second moving groove 28 to complete the fixation. This causes the moving sleeve 26 to disengage the connecting gear 9 from the second bevel gear 25, thereby achieving clamping by a single tightening device. When precise control of the clamping force of the friction plate 4 is required, the moving column 30 can be moved forward to drive the moving sleeve 26 to engage the connecting gear 9 with the other second bevel gears 25, thus completing the engagement of multiple connecting gears 9 with the second bevel gears 25, thereby completing the clamping of the friction plate 4 by multiple tightening devices and precisely controlling the clamping force of the friction plate 4.

[0058] The connecting gear 9 drives the outer second bevel gear 25 to rotate, thereby causing the vertically meshing bevel gear 23 to rotate. After the bevel gear 23 rotates, the rotating column drives the internal gear 22 to rotate. Since one end of the adjusting rod 15 is equipped with a connecting plate 19 and the other end is not, there is a vertical difference between the lower end of the adjusting rod 15 of the movable rod 13. There is a gear 22 between the upper and lower ends of the adjusting rod 15. The upper and lower ends of the adjusting rod 15 have toothed grooves 21. The rotation of the gear 22 drives the upper and lower ends of the adjusting rod 15 to move to the outer ends on both sides. The movement of the two adjusting rods 15 to both ends will drive the movable rod 13 into the limiting groove 16 in the limiting plate 12. The base point is rotated, and the lower end moves outward, causing the upper end of the movable rod 13 to move inward. The upper end of the movable rod 13 drives the clamping rod 14 to press inward. Since the clamping rod 14 is located in the support plate 11 and moves left and right, the upper end of the movable rod 13 is movably connected to the clamping rod 14 through the groove 17. This prevents the clamping rod 14 from interfering with the movable rod 13 when it tilts inward. The groove 17 allows the clamping rod 14 to move, thus smoothly pressing the clamping rod 14 inward. The two clamping rods 14 press the friction plate 4 through the clamping block 8, causing the friction plate 4 to drive the rotating shaft 3 to change the transmitted torque.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
