The camshaft is a key component in mechanical equipment such as internal combustion engines and engines. It is used to control the opening and closing of the valves, thereby regulating the intake and exhaust processes. During production and processing, the camshaft is usually formed by forging.

[0025] An environmentally friendly forging process for camshaft production includes the following specific steps:

[0026] S1. Place the camshaft blank to be forged on the lower die seat, drive the upper die seat down, and squeeze the blank between the upper and lower die seats to fill the die cavity.

[0027] S2. When the blank is cooled, the upper die seat is driven away from the blank, so that the two ejector rods drive the support blocks to move upward. The two support blocks lift the blank, align the two finger cylinders with both ends of the blank, and then use the finger cylinders to clamp both ends of the blank, and drive the rack rod to move away from between the lower die seat and the upper die seat;

[0028] S3, move the displacement plate horizontally until the blank is between the two limit plates, and the two ends of the blank are aligned with the grooves at the two ends of the support plate, then release the blank with the finger cylinder and place the blank on the support plate, so that each blank can be placed on a support plate at a different position;

[0029] S4. After the blank is placed on the pallet, the suction cup is used to hold the blank. At the same time, the hard tube is driven to rotate within a certain angle range, and the blank is also rotated synchronously. The worker can observe different positions of the blank by maintaining a fixed viewing angle.

[0030] S5. When the forging quality inspection of the billet is completed, the suction cup releases the billet, drives the turntable to tilt, aligns the limit plate on the turntable with the limit frame, and embeds the end of the support plate into the turntable. The billet will fall onto the turntable due to the loss of support of the support plate and is located between the two limit plates. The billet will then slide down to the collection table under the action of gravity and be located in one of the placement channels. The above operation is then repeated to make all billets with qualified forging quality slide into the placement channels on the collection table. Moreover, when the support plate moves downward, the filling plate fills the pit in the embedded area of ​​the end of the support plate. During the sliding process, the billet is always in contact with the plane and can slide normally.

[0031] S6. The limit frame no longer forms a limit area, and the end of the push plate contacts the surface of the material collection table. The push plate is moved horizontally to push multiple billets so that the billets with spacing are attached to each other. At this time, when the billets on the material collection table are transferred using the clamping device, all billets can be clamped at one time. Similarly, the above operation can be repeated to uniformly clamp billets with unqualified forging quality.

[0032] S7. During the forging process, the flue gas can be drawn into the activated carbon filter through the exhaust fan, and the flue gas is discharged through the activated carbon filter after purification.

[0033] The beneficial effects of the present invention are as follows:

[0034] 1. The environmentally friendly forging equipment and process for camshaft production described in the present invention utilizes a demoulding assembly, a material taking assembly, and a material storage assembly to realize automatic unloading and centralized arrangement of forged blanks, eliminating the need for manual removal of the blanks and saving manpower. At the same time, since the multiple support plates on the transfer table are arranged horizontally, the blanks are also placed on the support plates at a relatively uniform angle, which is convenient for workers to check the forging quality of the blanks, which is more orderly and not easy to confuse.

[0035] 2. The environmentally friendly forging equipment and process for camshaft production described in the present invention utilizes a rotary drive assembly. When a blank is placed on a support plate, multiple blanks can be driven to rotate synchronously. Workers can observe different positions of the blank by maintaining a fixed viewing angle, eliminating the need to manually adjust the blank angle, which is more convenient.

[0036] 3. The environmentally friendly forging equipment and process for camshaft production described in the present invention utilizes an intermittent pressing component and a material receiving component. After the billet forging quality inspection work is completed, the billets with qualified or unqualified forging quality on the turntable can be transferred to the collecting table in turn, and the original separated placement is changed to a tight fit, which is convenient for the clamping equipment to uniformly clamp multiple billets with qualified or unqualified forging quality, which is beneficial to improving the transportation efficiency of the billets. Moreover, when the support plate moves downward, the filling plate will slide on the turntable under the action of the connecting rod, so that the filling plate fills the pit in the embedded area of ​​the end of the support plate, so that the billet is always in contact with the plane during the sliding process, avoiding the situation where the billet cannot slide normally due to being stuck in the pit when sliding along the turntable, thereby affecting subsequent work.

[0037] 4. The present invention describes an environmentally friendly forging equipment and process for camshaft production. During the forging process, the flue gas can be drawn into the activated carbon filter by an exhaust fan. The flue gas is purified and then discharged through the activated carbon filter, thereby avoiding the flue gas from polluting the surrounding environment, which is more environmentally friendly.

[0054] A material taking component is also provided on the bottom plate 1;

[0055] The material taking assembly includes a displacement plate 6 slidably connected to one side of the upper end surface of the bottom plate 1, a lifting plate 19 slidably connected to one side of the displacement plate 6, a rack rod 16 slidably connected to one side of the lifting plate 19, and finger cylinders 15 are provided on both sides of the lower end surface of the rack rod 16;

[0056] A material storage component is also provided on the bottom plate 1;

[0057] The material storage assembly includes a turntable 9 rotatably arranged on one side of the upper end surface of the base plate 1, and a plurality of limit plates 25 are fixedly connected to the upper end surface of the turntable 9. A plurality of support plates 23 are plugged and slidably connected to the turntable 9. The support plate 23 is located between the two limit plates 25, and grooves for placing the ends of the camshafts are provided at both ends of the support plate 23.

[0058] In this embodiment, Figure 2 、 Figure 3 、 Figure 9 As shown, a hydraulic cylinder 5 is fixedly connected to one side of the upper end surface of the top plate 2, and the piston end of the hydraulic cylinder 5 is fixedly connected to one side of the upper end surface of the upper mold base 4. A cylinder three 48 is fixedly connected to one side of the lower end surface of the lower mold base 3, and the piston end of the cylinder three 48 is fixedly connected to the connecting plate 7. The lower end of the push rod 43 is fixedly connected to the connecting plate 7.

[0059] A threaded rod 12 is threadedly connected to one side of the lower end of the displacement plate 6. Both ends of the threaded rod 12 are rotatably set on the base plate 1. A motor 11 is fixedly connected to one side of the upper end surface of the base plate 1. The output end of the motor 11 is fixedly connected to one end of the threaded rod 12.

[0060] One end of the lifting plate 19 is threadedly connected to the threaded rod 2 18, and both ends of the threaded rod 2 18 are rotatably set on the displacement plate 6. One side of the upper end of the displacement plate 6 is fixedly connected to the motor 2 17, and the output end of the motor 2 17 is fixedly connected to one end of the threaded rod 2 18. A gear 20 is rotatably set on one side of the upper end of the lifting plate 19, and the gear 20 is engaged with the tooth block on the rack rod 16. One side of the upper end of the lifting plate 19 is fixedly connected to the motor 3 21, and the output end of the motor 3 21 is fixedly connected to the gear 20.

[0061] Specifically, when the existing automobile camshaft forging mold is in use, after the camshaft blank is formed, the worker needs to manually take the blank out of the mold cavity and place it in a container for collection. When a large number of camshafts need to be forged, the worker needs to frequently take out the blank. The whole process is time-consuming and labor-intensive. Moreover, usually, after the blank is forged, the forging quality of the blank needs to be inspected. The blanks placed in the container are relatively messy, which is not conducive to quality inspection and is easy to be confused.

[0062] Therefore, to solve the above problems, when using this embodiment, the camshaft blank to be forged is placed on the lower die base 3. The upper die base 4 is then driven downward by the hydraulic cylinder 5. The upper die base 4 and the lower die base 3 squeeze the blank, causing the blank to fill the die cavity. In addition, the support block 14 is initially at the bottom of the lower die cavity, filling the hole at the bottom of the lower die cavity. Therefore, the support block 14, the upper die base 4, and the lower die base 3 cooperate to form a sealed camshaft die cavity. After the blank has cooled, the upper die base 4 is driven away from the blank.

[0063] The connecting plate 7 is driven to rise by the cylinder 3 48, so that the two push rods 43 drive the support blocks 14 to move upward. Since the support blocks 14 are aligned with the two ends of the camshaft blank, the two support blocks 14 lift the blank. At the same time, the motor 3 21 drives the gear 20 to rotate, so that the rack rod 16 slides on the lifting plate 19, so that the two finger cylinders 15 are aligned with the two ends of the blank, and then the finger cylinders 15 are used to clamp the two ends of the blank. The finger cylinder 15 is a device for clamping objects in the prior art and will not be described in detail here. Then the rack rod 16 is driven to move away from between the lower mold base 3 and the upper mold base 4, and the position is adjusted by the rotation of the threaded rod 12 driven by the motor 11. The shift plate 6 moves horizontally until the blank is between the two limit plates 25, and the two ends of the blank are aligned with the grooves at the two ends of the support plate 23, and then the finger cylinder 15 releases the blank and places the blank on the support plate 23. Then the above operation is repeated, and each blank can be placed on a support plate 23 at a different position, thereby realizing the automatic unloading and centralized arrangement of the blanks after forging, eliminating the process of manually taking out the blanks, and saving manpower. At the same time, since the multiple support plates 23 on the transfer table 9 are arranged horizontally, the blanks are also placed on the support plates 23 at a more uniform angle, which is convenient for workers to check the forging quality of the blanks, which is more orderly and not easy to confuse.

[0064] In this embodiment, Figure 4 、 Figure 5 、 Figure 7 As shown, a rotation drive assembly is also provided on the turntable 9;

[0065] The rotary drive assembly includes a mounting plate 34 fixedly connected to one side of the turntable 9. The mounting plate 34 is laterally arranged and rotatably provided with multiple hard tubes 47. A suction cup 36 is provided at one end of the hard tube 47. A vacuum pump 24 is fixedly connected to one side of the upper end surface of the mounting plate 34. The air inlet end of the vacuum pump 24 is connected to a long tube 35. A plurality of hoses 52 are provided on the long tube 35. One end of the hose 52 is connected to one side of the hard tube 47. A motor four 22 is fixedly connected to one side of the upper end surface of the base plate 1, and the output end of the motor four 22 is fixedly connected to the turntable 9.

[0066] One end of the hard tube 47 is fixedly connected to a worm gear 33, and both ends of the mounting plate 34 are rotatably provided with a worm 32. The worm 32 is provided with multiple sections of worm teeth, and the worm teeth are meshed with the worm gear 33. One end of the mounting plate 34 is fixedly connected to a motor 30, and the output end of the motor 30 is fixedly connected to one end of the worm 32.

[0067] Specifically, in the above embodiment, although the forged blank can be placed on the support plate 23 to facilitate workers to check its forging quality, the workers can only easily observe the upward side of the blank, while the other directions are not easy to observe. It is also necessary to manually adjust the angle of the blank to observe various positions of the blank. The whole process is relatively troublesome. Therefore, in order to solve the above problem, when this embodiment is in use, after the blank is placed on the support plate 23, the motor 22 drives the turntable 9 to rotate. Under the action of gravity, the end of the blank is tightly fitted with the suction cup 36, and then the air at the suction cup 36 is extracted by the vacuum pump 24, so that the suction cup 36 adsorbs the blank. At the same time, the motor 30 drives the worm 32 to rotate, so that the multiple worm gears 33 and the hard tube 47 rotate at the same time. Moreover, since the hose 52 has a certain length, when the hose 52 rotates following the hard tube 47, there will be no situation where the airway is blocked due to the hose 52 being pulled. The blank also rotates synchronously, so workers can observe different positions of the blank by maintaining a fixed viewing angle, eliminating the need to manually adjust the blank angle and making it more convenient.

[0068] In this embodiment, Figure 5 、 Figure 7 、 Figure 8 As shown, a plurality of spring dampers 44 are provided on the lower end surface of the turntable 9, the piston end of the spring damper 44 is fixedly connected to the support plate 23, a connecting rod 46 is rotatably provided on one side of the support plate 23, and a filling plate 45 is rotatably provided on one end of the connecting rod 46, and the filling plate 45 is plugged into and slidably connected to the turntable 9.

[0069] The transfer table 9 is also provided with an intermittent pressing component;

[0070] The intermittent pressing assembly includes a slider 26 slidably connected to one side of the turntable 9, one end of the slider 26 is rotatably provided with a pressure rod 29, one end of the slider 26 is fixedly connected to a motor 6 28, the output end of the motor 6 28 is fixedly connected to one end of the pressure rod 29, one end of the slider 26 is threadedly connected to a threaded rod 3 31, both ends of the threaded rod 3 31 are rotatably provided on the turntable 9, one side of the turntable 9 is fixedly connected to a motor 5 27, the output end of the motor 5 27 is fixedly connected to one end of the threaded rod 3 31;

[0071] The bottom plate 1 is also provided with a material receiving assembly;

[0072] The material receiving assembly includes a material collection table 8 fixedly connected to one side of the upper end surface of the base plate 1, a limit frame 38 is inserted and slidably connected to the material collection table 8, a support plate 41 is slidably connected to one side of the material collection table 8, a cylinder 2 42 is fixedly connected to one side of the upper end of the support plate 41, and a push plate 13 is fixedly connected to the piston end of the cylinder 2 42, a cylinder 1 37 is fixedly connected to one side of the material collection table 8, and the piston end of the cylinder 1 37 is fixedly connected to one side of the limit frame 38, one end of the support plate 41 is threadedly connected to a threaded rod 4 40, both ends of the threaded rod 40 are rotatably set on the material collection table 8, one side of the material collection table 8 is fixedly connected to a motor 8 39, and the output end of the motor 8 39 is fixedly connected to one end of the threaded rod 4 40.

[0073] Specifically, in the above embodiment, after the inspection of the blanks on the transfer table 9 is completed, the blanks with qualified quality and those with unqualified quality need to be collected separately. In some cases, the blanks with qualified forging quality and those with unqualified quality need to be transferred to the next process respectively by a clamping device. However, since the multiple blanks are separated, it is difficult for the clamping device to clamp all the blanks with qualified or unqualified forging quality at one time, thereby affecting the subsequent transfer efficiency.

[0074] Therefore, in order to solve the above problem, in use, this embodiment, after the forging quality inspection of the billet is completed, gas is introduced into the place where the suction cup 36 and the billet are attached, so that the suction cup 36 loosens the billet, and then the turntable 9 is driven to tilt, so that the limit plate 25 on the turntable 9 is aligned with the limit frame 38, and a plurality of placement channels are provided on the limit frame 38. First, according to the position of the billet with qualified forging quality, the motor five 27 drives the threaded rod three 31 to rotate, so that the slider 26 slides horizontally on the turntable 9, so that the pressure rod 29 moves to above the corresponding end of the support plate 23, and then the motor six 28 drives the pressure rod 29 to rotate, so that the pressure rod 29 pushes the support plate 23 downward, and the end of the support plate 23 is embedded in the turntable 9. The billet will fall onto the turntable 9 due to the loss of support of the support plate 23 and is located between the two limit plates 25. The billet will slide onto the collection table 8 under the action of gravity and is located in one of the placement channels. The first step is to move the push plate 13 to the upper edge of the transfer table 8, and then the second step is to move the push plate 13 to the upper edge of the transfer table 8, so that the second step is to move the push plate 13 to the upper edge of the transfer table 8.

[0075] Therefore, when the blank slides along the turntable 9, due to the irregular protrusions on the surface of the blank, the blank is very easy to get stuck in the pit, resulting in the blank being unable to slide down normally, affecting subsequent work. Therefore, in order to solve this problem, when the pallet 23 moves downward, the filling plate 45 will slide on the turntable 9 under the action of the connecting rod 46, so that the filling plate 45 fills the pit in the embedded area of ​​the end of the pallet 23, so that the blank is always in contact with the plane during the sliding process, avoiding the blank being stuck in the pit when sliding down the turntable 9, resulting in the blank being unable to slide down normally, affecting subsequent work.

[0076] In this embodiment, Figure 1As shown, an activated carbon filter 50 is fixedly connected to one side of the upper end surface of the top plate 2, and an exhaust fan 51 is connected to one side of the activated carbon filter 50. The air inlet end of the exhaust fan 51 is connected to a dust hood 49, and the dust hood 49 is fixedly connected to the top plate 2.

[0077] Specifically, during the forging process, the smoke can be drawn into the activated carbon filter 50 by the exhaust fan 51. The smoke is purified and then discharged through the activated carbon filter 50, thereby avoiding the smoke from polluting the surrounding environment, which is more environmentally friendly.

[0078] An environmentally friendly forging process for camshaft production includes the following specific steps:

[0079] S1. Place the camshaft blank to be forged on the lower die base 3, drive the upper die base 4 down, and squeeze the blank between the upper die base 4 and the lower die base 3 to fill the die cavity.

[0080] S2. When the blank is cooled, the upper mold base 4 is moved away from the blank, so that the two ejector rods 43 drive the support block 14 to move upward. The two support blocks 14 lift the blank, so that the two finger cylinders 15 are aligned with both ends of the blank. Then, the finger cylinders 15 are used to clamp both ends of the blank, and the rack rod 16 is driven to move away from between the lower mold base 3 and the upper mold base 4.

[0081] S3, move the displacement plate 6 horizontally until the blank is between the two limit plates 25, and the two ends of the blank are aligned with the grooves at the two ends of the support plate 23, then release the blank by the finger cylinder 15, and place the blank on the support plate 23, so that each blank can be placed on the support plate 23 at a different position;

[0082] S4. After the blank is placed on the support plate 23, the suction cup 36 is used to hold the blank. At the same time, the hard tube 47 is driven to rotate within a certain angle range. The blank also rotates synchronously. The worker can observe different positions of the blank by maintaining a fixed viewing angle.

[0083] S5. When the forging quality inspection of the billet is completed, the suction cup 36 releases the billet and drives the turntable 9 to tilt, so that the limit plate 25 on the turntable 9 is aligned with the limit frame 38, so that the end of the support plate 23 is embedded in the turntable 9. The billet will fall onto the turntable 9 due to the loss of the support of the support plate 23 and is located between the two limit plates 25. The billet will slide down to the collection table 8 under the action of gravity and be located in one of the placement channels. Then, the above operation is repeated to make the billets with qualified forging quality slide into the placement channels on the collection table 8. Moreover, when the support plate 23 moves downward, the filling plate 45 fills the pit in the embedded area of ​​the end of the support plate 23. The billet is always in contact with the plane during the sliding process and can slide normally.

[0084] S6, so that the limit frame 38 no longer forms a limit area, the end of the push plate 13 contacts the surface of the collection table 8, and the push plate 13 is moved horizontally to push multiple billets so that the billets with spacing are attached to each other. At this time, when the billets on the collection table 8 are transferred by the clamping device, all billets can be clamped at one time. Similarly, the above operation is repeated to uniformly clamp the billets with unqualified forging quality.

[0085] S7. During the forging process, the exhaust fan 51 can draw the flue gas into the activated carbon filter 50, and the flue gas is discharged through the activated carbon filter 50 after being purified.

[0086] Working principle: Place the camshaft blank to be forged on the lower die seat 3, and then use the hydraulic cylinder 5 to drive the upper die seat 4 to descend. The upper die seat 4 and the lower die seat 3 extrude the blank to fill the die cavity. When the blank is cooled, drive the upper die seat 4 away from the blank; drive the connecting plate 7 to rise through the cylinder three 48, so that the two push rods 43 drive the support block 14 to move upward. Since the support blocks 14 are aligned with the two ends of the camshaft blank, the two support blocks 14 lift the blank. At the same time, the motor three 21 drives the gear 20 to rotate, so that the rack rod 16 slides on the lifting plate 19, so that the two finger cylinders 15 are aligned with the two ends of the blank, and then use the finger cylinders 15 to clamp the two ends of the blank, and then drive the rack rod 16 from the lower die seat 3 and The upper die seat 4 is moved away, and the displacement plate 6 is moved horizontally under the action of the motor 11 driving the threaded rod 12 to rotate until the blank is between the two limit plates 25, and the two ends of the blank are respectively aligned with the grooves at the two ends of the support plate 23, and then the finger cylinder 15 releases the blank and places the blank on the support plate 23, and then repeats the above operation, so that each blank can be placed on the support plate 23 at a different position, thereby realizing the automatic unloading and centralized arrangement of the blank after forging, eliminating the process of manually taking out the blank, saving manpower, and at the same time, since the multiple support plates 23 on the turntable 9 are arranged horizontally, the blank is also placed on the support plate 23 at a more uniform angle, which is convenient for workers to check the forging quality of the blank, more orderly. , not easy to be confused, when the blank is placed on the support plate 23, the motor 22 drives the turntable 9 to rotate, and under the action of gravity, the end of the blank is closely fitted with the suction cup 36, and then the air at the suction cup 36 is extracted by the vacuum pump 24, so that the suction cup 36 adsorbs the blank. At the same time, the motor 30 drives the worm 32 to rotate, so that the multiple worm gears 33 and the hard tube 47 rotate at the same time, and the hose 52 allows the hard tube 47 to rotate within a certain angle range, and the blank also rotates synchronously, then the worker can observe different positions of the blank by maintaining a fixed viewing angle, eliminating the process of manually adjusting the blank angle, which is more convenient. After the billet forging quality inspection is completed, gas is introduced into the attachment point between the suction cup 36 and the blank to make the suction cup 36 loosen the blank, and then the middle The turntable 9 is tilted so that the limit plate 25 on the turntable 9 is aligned with the limit frame 38, and a plurality of placement channels are provided on the limit frame 38. First, according to the position of the billet with qualified forging quality, the motor five 27 drives the threaded rod three 31 to rotate, so that the slider 26 slides horizontally on the turntable 9, and the pressure rod 29 moves to above the corresponding end of the support plate 23. Then, the motor six 28 drives the pressure rod 29 to rotate, so that the pressure rod 29 pushes the support plate 23 downward, and the end of the support plate 23 is embedded in the turntable 9. The billet will fall onto the turntable 9 due to the loss of support of the support plate 23 and is located between the two limit plates 25. Then, the billet will slide onto the collecting table 8 under the action of gravity and be located in one of the placement channels. Then repeat the above operation.The blanks with qualified forging quality can be made to slide into the placement channel on the material collection platform 8, and then the cylinder 1 37 is used to drive the limit frame 38 to slide, so that the limit frame 38 no longer forms a limit area. At the same time, the cylinder 2 42 drives the push plate 13 to move until the end of the push plate 13 contacts the surface of the material collection platform 8, and then the motor 8 39 drives the threaded rod 4 40 to rotate, so that the push plate 13 moves horizontally to push multiple blanks, so that the blanks with spacing are fitted together. At this time, the collection is clamped by the clamping device. When the blanks on the material table 8 are transferred, all the blanks can be clamped at one time. Similarly, by repeating the above operation, the blanks with unqualified forging quality can be clamped at the same time, thereby avoiding the situation that after the inspection of the blanks on the transfer table 9 is completed, due to the multiple blanks being separated, the clamping equipment is difficult to clamp all the blanks with qualified or unqualified forging quality at one time, affecting the subsequent transfer efficiency; although the above method can realize the transfer of the blanks from the transfer table 9 to the collection table 8, and the blanks are attached to each other, but Therefore, when the blank slides along the turntable 9, due to the irregular protrusions on the surface of the blank, the blank is very easy to get stuck in the pit, resulting in the blank being unable to slide down normally, affecting subsequent work. Therefore, in order to solve this problem, when the support plate 23 moves downward, the filling plate 45 will slide on the turntable 9 under the action of the connecting rod 46, so that the filling plate 45 fills the pit in the embedded area of ​​the end of the support plate 23, so that the blank is always in contact with the plane during the sliding process, avoiding the situation that the blank cannot slide down normally due to being stuck in the pit when sliding along the turntable 9, affecting subsequent work. During the forging process, the exhaust fan 51 can be used to draw the smoke into the activated carbon filter 50, and the smoke is discharged through the activated carbon filter 50 after purification, thereby avoiding the smoke pollution of the surrounding environment, which is more environmentally friendly. ,
