Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, and in particular to a stabilizer bar bushing secondary vulcanization equipment. Background Art

[0002] The automobile stabilizer bar bushing is a component that is used to install the stabilizer bar in the stabilizer bar bracket. Its function is to provide support and shock absorption between the stabilizer bar and the stabilizer bar bracket. It needs to have certain vibration damping and buffering properties, as well as stability when assembled with the stabilizer bar bracket.

[0003] Generally, after the automobile stabilizer bar bushing is vulcanized and formed once during the manufacturing process, it needs to be vulcanized again. The core of the secondary vulcanization is to further optimize the performance of the rubber material through a certain period of heating treatment. For example, a secondary vulcanization device for automobile stabilizer bar bushings with publication number CN117140801A includes a bottom plate, and a plurality of vulcanization matching plates are arranged above the bottom plate.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention drives the fan to drive the hot air to circulate through the liner assembly in the vulcanization box to achieve cyclic heating treatment, and the driving fan realizes deceleration transmission through the first rotating wheel, the second rotating wheel, the second transmission belt and other components, so that the extension shaft rotates at a reduced speed, and the extension shaft drives the transmission roller arranged in the vulcanization box to rotate through the transmission wheel, the transmission chain and other mechanisms, and the transmission roller drives the first transmission belt to run.

[0021] 2.

[0037] 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.

[0038] like Figure 1-Figure 12 As shown, a secondary vulcanization equipment for a stabilizer bar bushing is provided. It should be noted that, for the bushing member 24 of the stabilizer bar that needs secondary vulcanization, the core of the process is to rely on the action of hot air to remove post-crosslinking and volatiles. Therefore, the vulcanization equipment disclosed in the present invention includes a vulcanization box 1 and a warm air box 15. The air outlet of the warm air box 15 is connected to the back of the vulcanization box 1, and hot air is transported into the vulcanization box 1. A circulation pipe 14 is connected between the air inlet of the warm air box 15 and the front of the vulcanization box 1. The warm air box 15 transports hot air from the back of the vulcanization box 1, and then the hot air passes through the bushing member 24 placed inside the vulcanization box 1 to heat the bushing member 24, and then returns to the warm air box 15 through the circulation pipe 14 to realize hot air circulation, so as to heat the bushing member 24 conveniently.

[0039] The vulcanization equipment further includes a bushing positioning and lifting mechanism and a hot air driving mechanism, and the bushing positioning and lifting mechanism includes a roller assembly for lifting the bushing member 24, and a rotating driving mechanism matched with the roller assembly is arranged inside the vulcanization box 1, and the rotating driving mechanism is used to drive the roller assembly to rotate, so as to facilitate the rotation of the lifted bushing member 24, and facilitate the effective heating of the bushing member 24 as a whole;

[0040] The hot air driving mechanism is arranged in the warm air box 15. The hot air driving mechanism drives the hot air to circulate through rotational motion, and a transmission mechanism is arranged between the hot air driving mechanism and the rotational driving mechanism. The transmission mechanism is used to transmit the rotational driving force of the hot air driving mechanism to the rotational driving mechanism, so that the rotational driving mechanism can also drive the roller assembly to rotate without the need for an additional power source.

[0041] In some specific embodiments, such as Figure 8 and Fig. 9 As shown, the bushing positioning and lifting mechanism also includes a detachable support plate 25, and a plurality of detachable support plates 25 are provided and longitudinally distributed in the vulcanization box 1. The detachable support plate 25 is detachably connected in the vulcanization box 1, and a plurality of positioning holes 36 are evenly opened on each detachable support plate 25. The positioning holes 36 longitudinally penetrate the detachable support plate 25, and a group of roller shaft assemblies are arranged in each positioning hole 36, so that the bushing member 24 can be swung into the positioning hole 36 and supported by the corresponding roller shaft assembly.

[0042] The detachable connection between the detachable support plate 25 and the vulcanization box 1 can be specifically as follows: mounting holes 44 are provided on both sides of each detachable support plate 25, and support hooks 30 matching the mounting holes 44 are fixedly installed on the inner walls on both sides of the vulcanization box 1. The support hooks 30 are distributed in multiple groups longitudinally, and handles are fixedly installed on both sides of the detachable support plate 25 for easy transportation.

[0043] After the lining member 24 is placed on the entire detachable support plate 25, the detachable support plate 25 is sent to the interior of the vulcanization box 1, and the mounting holes 44 on both sides are aligned with the corresponding support hooks 30, and then they are docked and hung.

[0044] In some specific embodiments, the roller assembly includes a roller body 27, two roller bodies 27 are provided and symmetrically distributed in the positioning hole 36, each roller body 27 is connected to the inner wall of the corresponding positioning hole 36 by rotation, and the roller body 27 is provided with an annular positioning groove that cooperates with the lining member 24, which can prevent the placed lining member 24 from being displaced along the axial direction of the roller body 27, and the roller body 27 cooperates with the rotating drive mechanism.

[0045] In some specific embodiments, such as Figure 7As shown, there are multiple groups of rotary drive mechanisms, which are longitudinally equidistantly distributed inside the vulcanization box 1 and are respectively arranged corresponding to the placed detachable pallets 25. Each group of rotary drive mechanisms includes a transmission roller 18 and a first transmission belt 29. Two transmission rollers 18 are provided and are rotatably connected to the two sides inside the vulcanization box 1, and the first transmission belt 29 is cooperatively connected between the two transmission rollers 18. The first transmission belt 29 is used to contact the roller assembly. The transmission roller 18 is cooperatively connected with the transmission mechanism. After the detachable pallet 25 is installed and placed inside the vulcanization box 1, the bottoms of all roller bodies 27 on the same detachable pallet 25 are in contact with the corresponding upper surface of the first transmission belt 29. At this time, when the transmission roller 18 drives the first transmission belt 29 to run, the first transmission belt 29 can make all roller bodies 27 on the same detachable pallet 25 rotate, thereby facilitating the self-rotation of the lining member 24 on the two roller bodies 27 distributed in pairs, which is convenient for heating and dispersing volatiles.

[0046] In some specific embodiments, in combination Figure 8 and Fig.11 As shown, the transmission mechanism includes an extension shaft 33, which is coaxially fixedly connected to a drive roller 18 in one group of rotary drive mechanisms, and the extension shaft 33 extends into the warm air box 15. A reduction transmission mechanism is connected between the end of the extension shaft 33 in the warm air box 15 and the rotating end of the hot air drive mechanism. A linkage mechanism that is connected to each drive roller 18 is also provided inside the vulcanization box 1.

[0047] Among them, Figure 8 As shown, the linkage mechanism includes a transmission wheel 21 and a transmission chain 22. Each transmission roller 18 in each set of rotary drive mechanisms is coaxially fixedly connected with a transmission wheel 21. The transmission wheels 21 on the longitudinally aligned transmission rollers 18 are connected through the same transmission chain 22. Here, the transmission chain 22 can be set as a chain, and the transmission wheel 21 can be set as a chain plate to facilitate effective transmission. Two transmission rollers 18 of one set of rotary drive mechanisms are coaxially fixedly connected with a first synchronous wheel 23. The two first synchronous wheels 23 are connected with a first synchronous belt 31. The cooperation of the first synchronous wheel 23 and the first synchronous belt 31 can synchronize the transmission rollers 18 on both sides. Rotate, and the transmission wheel 21 and the transmission chain 22 can make the longitudinal transmission roller 18 rotate. When the extension shaft 33 is driven by the reduction transmission mechanism under the operation of the hot air drive mechanism, the extension shaft 33 drives the corresponding transmission roller 18 to rotate. The corresponding transmission roller 18 relies on the transmission wheel 21 and the transmission chain 22 for longitudinal transmission. At the same time, the corresponding transmission roller 18 relies on the first synchronous wheel 23 and the first synchronous belt 31 for transverse transmission, so that the transmission rollers 18 on both sides of each group of rotating drive mechanisms can rotate synchronously in the same direction, so as to facilitate the operation of the first transmission belt 29 and facilitate the rotation of the roller shaft assemblies on the detachable pallet 25 at different positions.

[0048] In some specific embodiments, the reduction transmission mechanism includes a first wheel 40, a second wheel 39 and a second transmission belt 38. The first wheel 40 is coaxially fixedly connected to the rotating end of the hot air driving mechanism. The second wheel 39 is rotatably arranged in the warm air box 15, and the size of the second wheel 39 is larger than that of the first wheel 40. The specific size ratio can be selected and adjusted according to actual deceleration needs. The first wheel 40 and the second wheel 39 are connected by the second transmission belt 38. One end of the extension shaft 33 inside the warm air box 15 is coaxially fixedly connected to the second wheel 39 with a second synchronous wheel 41, and a second synchronous belt 42 is connected between the two second synchronous wheels 41.

[0049] When the hot air driving mechanism is running, it drives the second wheel 39 to rotate through the first wheel 40 and the second transmission belt 38. Since the size of the second wheel 39 is larger than that of the first wheel 40, speed reduction transmission is achieved to prevent the hot air driving mechanism from rotating too fast and causing the liner member 24 to rotate too fast. The second wheel 39 drives the extension shaft 33 to rotate through the second transmission belt 38 and the second synchronous belt 42.

[0050] In some specific implementation schemes, such as Figure 2 and Fig.11 As shown, the hot air driving mechanism includes a driving fan 37, which is installed inside the warm air box 15 and driven to rotate by a motor to drive air flow; a connecting pipe 19 is connected between the warm air box 15 and the vulcanizing box 1, and a plurality of connecting pipes 19 can be provided, one end of the connecting pipe 19 faces the blowing direction of the driving fan 37, and the other end is connected to the back of the vulcanizing box 1, that is, the air blown by the driving fan 37 can enter the connecting pipe 19, and then enter the vulcanizing box 1, and an adjustable electric heating element 20 is installed on the inner wall of the connecting pipe 19, and the adjustable electric heating element 20 is heated and the temperature can be adjusted. When the air driven by the driving fan 37 passes through the connecting pipe 19, it is heated by the adjustable electric heating element 20 to become hot air.

[0051] In some specific embodiments, such as Figure 1 As shown, a box door 2 is installed on the front of the vulcanization box 1, and a plurality of main pipe bodies 6 are longitudinally distributed on the box door 2. A return air pipe 11 and an exhaust pipe 7 are arranged on each main pipe body 6. The return air pipe 11 on each main pipe body 6 is connected with the circulation pipe 14 through a hose, and an external valve is arranged on the return air pipe 11. The external valve is used to connect the return air pipe 11 with the external environment. The hose connection is mainly used to consider the switch problem of the box door 2 to prevent interference with the switch of the box door 2; the exhaust pipe 7 is connected with an external solution tank for absorbing and treating volatiles through a hose, and a flow direction switching rotary valve is arranged in each main pipe body 6. The flow direction switching rotary valve is used to switch the connection state between the return air pipe 11 and the exhaust pipe 7 and the main pipe body 6. A switching drive mechanism for driving the flow direction switching rotary valve to rotate is arranged on the box door 2.

[0052] Among them, combined Figure 2 and Figure 3 As shown, the flow direction switching rotary valve includes a valve core 8, which is rotatably connected in the main body 6, and one end of the valve core 8 extends to the outside of the main body 6, and the outer side of the valve core 8 is in contact with the inner wall of the main body 6, and a rubber ring can be installed between the two to enhance the sealing performance. A main port 17 is provided on the side of the valve core 8 facing the inside of the vulcanization box 1, and a first port 16 and a second port 28 are provided on the inner wall of the main body 6 that is in contact with the valve core 8. The first port 16 and the second port 28 are both connected to the main port 17, the first port 16 is used to communicate with the return air pipe 11, and the second port 28 is used to communicate with the return air pipe 11. The exhaust pipe 7 is connected, and there is a certain angle between the first port 16 and the second port 28. When the first port 16 is connected to the return air pipe 11, the second port 28 cannot be connected to the exhaust pipe 7 and is in a closed state. On the contrary, when the first port 16 is disconnected from the return air pipe 11, the second port 28 is connected to the exhaust pipe 7, which can be switched by rotating the valve core 8. The switching drive mechanism is used to drive the valve core 8 to rotate, and the end of the valve core 8 outside the main body 6 is also fixedly connected to a push handle 9 for pushing the external valve to open, and the push handle 9 rotates with the valve core 8.

[0053] In some specific embodiments, the external valve includes a connecting guide rail 13 and a blocking slider 10, the connecting guide rail 13 is fixedly connected to the outer wall of the return air pipe 11, the blocking slider 10 is slidably connected to the connecting guide rail 13, and a spring is also connected between the blocking slider 10 and the connecting guide rail 13, an external opening 43 is opened on the return air pipe 11, the blocking slider 10 is used to block the external opening 43, and the blocking slider 10 cooperates with the push handle 9. It should be noted that in order to facilitate the blocking slider 10 to effectively block the external opening 43, the return air pipe 11 can be set as a square tube, and the external opening 43 is opened on the plane outer wall of the return air pipe 11, and the blocking slider 10 fits the plane outer wall of the return air pipe 11.

[0054] When the valve core 8 rotates counterclockwise, it drives the push handle 9 to rotate, and the push handle 9 squeezes the blocking slider 10, causing the blocking slider 10 to slide along the connecting guide rail 13 and compress the spring, and finally the blocking slider 10 is separated from the external opening 43. In this process, the first opening 16 is misaligned with the return air pipe 11, so the return air pipe 11 can only communicate with the external environment through the external opening 43. For details, please refer to Figure 4 and Figure 5 .

[0055] In some specific embodiments, such as Figure 1As shown, the switching drive mechanism includes a hydraulic telescopic rod 4 and a rack 5. The hydraulic telescopic rod 4 is fixedly installed on the outside of the box door 2, and the rack 5 is fixedly connected to the telescopic end of the hydraulic telescopic rod 4. Each valve core 8 is coaxially fixedly connected with a gear 12 meshing with the rack 5, and the gear 12 is located outside the main pipe body 6. After the liner kit 24 is heated in the vulcanization box 1 for a period of time, in order to facilitate the discharge of volatiles flowing with the circulating hot air, the hydraulic telescopic rod 4 is started, the hydraulic telescopic rod 4 is extended, and the rack 5 is driven to rise, and the rack 5 drives all the gears 12 to rotate, thereby rotating all the valve cores 8 to achieve gas flow direction regulation.

[0056] In some specific embodiments, such as Fig.10 As shown, a temperature adjustment knob switch 32 electrically connected to the adjustable electric heating element 20 is fixedly installed on the outer wall of the vulcanization box 1, and the temperature adjustment knob switch 32 adjusts the power of the adjustable electric heating element 20 by rotating the knob, so as to facilitate the adjustment of its heating temperature; a linkage wheel 34 is coaxially fixedly connected to the extension shaft 33, and the temperature adjustment knob switch 32 and the linkage wheel 34 are close to each other but not in contact, the telescopic end of the hydraulic telescopic rod 4 is fixedly connected to the extension frame 26, and a transition wheel 35 is connected through the extension frame 26, and the transition wheel 35 is aligned with the position between the temperature adjustment knob switch 32 and the linkage wheel 34, and the transition wheel 35 is rotatable.

[0057] During the normal circulation of hot air, the transition wheel 35 is not in contact with the temperature adjustment knob switch 32 and the linkage wheel 34. When the hydraulic telescopic rod 4 is extended, the rack 5 drives each valve core 8 to deflect a certain angle to achieve the switching of the air flow direction. At this time, the hydraulic telescopic rod 4 just drives the transition wheel 35 to rise and contact between the temperature adjustment knob switch 32 and the linkage wheel 34. Since the driving fan 37 is linked to the rotation of the extension shaft 33, the linkage wheel 34 on the extension shaft 33 rotates synchronously, and the linkage wheel 34 drives the temperature adjustment knob switch 32 through the transition wheel 35. The temperature regulating knob switch 32 rotates, at this time, the rotation direction of the temperature regulating knob switch 32 is the direction of decreasing the temperature, and because the extension shaft 33 has been decelerated, it can ensure that the temperature regulating knob switch 32 rotates slowly, and gradually decreases the temperature of the adjustable electric heating element 20, so that the air driven by the driving fan 37 gradually cools down, and at this time, the air driven by the driving fan 37 draws normal temperature air from the outside through the external port 43 on the return air pipe 11, so as to facilitate the gradual cooling of the liner kit 24 inside the vulcanization box 1, and also facilitate the removal of volatiles in the vulcanization box 1.

[0058] It should be noted that, in order to facilitate opening of the box door 2, an electric guide rail 3 is installed at the bottom of the front side of the vulcanization box 1, and the box door 2 is slidably set on the electric guide rail 3, and the box door 2 is opened and closed by horizontal sliding.

[0059] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0060] First, place the lining member 24 that needs to be vulcanized for the second time into the positioning hole 36 on the removable pallet 25, and support it with the roller assembly. Then install the removable pallet 25 inside the vulcanization box 1. At this time, the bottoms of all the roller assemblies on the same removable pallet 25 are in contact with the upper surface of the corresponding first transmission belt 29. Then close the box door 2. At this time, the first ports 16 are connected with the return air pipe 11 to form a circulating air path. Then start the driving fan 37. The air driven by the driving fan 37 passes through the connecting pipe 19 and is heated by the adjustable electric heating element 20 to become hot air. Then, the air enters the vulcanization box 1 to heat all the lining members 24. The post-crosslinking and volatiles are removed by the action of the hot air. The hot air enters the main port 17 through the main pipe 6, and then enters the return air pipe 11 through the first port 16. Finally, it returns to the warm air box 15 through the circulation pipe 14 to realize the circulation flow, which is convenient for heating the lining member 24.

[0061] During the operation of the driving fan 37, the second rotating wheel 39 is driven to rotate through the first rotating wheel 40 and the second transmission belt 38. Since the size of the second rotating wheel 39 is larger than that of the first rotating wheel 40, the speed reduction transmission is realized to avoid the driving fan 37 from rotating too fast and causing the lining member 24 to rotate too fast; the second rotating wheel 39 drives the extension shaft 33 to rotate through the second transmission belt 38 and the second synchronous belt 42; the extension shaft 33 drives the corresponding transmission roller 18 to rotate, and the corresponding transmission roller 18 is longitudinally driven by the transmission wheel 21 and the transmission chain 22, and the corresponding transmission roller 18 is transversely driven by the first synchronous wheel 23 and the first synchronous belt 31, so that the transmission rollers 18 on both sides of each set of rotating drive mechanisms are synchronously rotated in the same direction, so that the first transmission belt 29 is operated, so that the roller assemblies on the detachable support plates 25 at different positions are rotated, so that the lining member 24 supported by the roller assembly is rotated, so that the lining member 24 is effectively and evenly heated as a whole, and the volatiles generated by heating are discharged.

[0062] After the liner assembly 24 is heated in the vulcanization box 1 for a period of time, in order to facilitate the discharge of volatiles circulating with the circulating hot air, the hydraulic telescopic rod 4 is started, the hydraulic telescopic rod 4 is extended, and the rack 5 is driven to rise. The rack 5 drives all the gears 12 to rotate, so that all the valve cores 8 rotate counterclockwise.

[0063] When the valve core 8 rotates counterclockwise, it drives the push handle 9 to rotate, and the push handle 9 squeezes the blocking slider 10, causing the blocking slider 10 to slide along the connecting guide rail 13 and compress the spring, and finally the blocking slider 10 is separated from the external port 43, so that the return air pipe 11 is connected with the external environment, and in this process, the first port 16 and the return air pipe 11 are offset, that is, the first port 16 is closed, and the second port 28 is aligned and connected with the exhaust pipe 7, so that the air passing through the vulcanization box 1 is discharged from the exhaust pipe 7 through the main port 17 and the second port 28, and enters the volatile absorption liquid box, and the driving fan 37 continuously draws new air from the external environment into the vulcanization box 1 through the external port 43, so as to drive the volatiles to be discharged.

[0064] When the hydraulic telescopic rod 4 is extended, it just drives the transition wheel 35 to rise and contact between the temperature adjustment knob switch 32 and the linkage wheel 34. Since the driving fan 37 is linked to the extension shaft 33 to rotate, the linkage wheel 34 on the extension shaft 33 rotates synchronously, and the linkage wheel 34 drives the temperature adjustment knob switch 32 to rotate through the transition wheel 35. At this time, the rotation direction of the temperature adjustment knob switch 32 is the direction of reducing the temperature, and since the extension shaft 33 has been decelerated, it can be ensured that the temperature adjustment knob switch 32 rotates slowly, and gradually reduces the temperature of the adjustable electric heating element 20, so that the temperature of the hot air driven by the driving fan 37 to enter the vulcanization box 1 is gradually reduced, and at this time, the air driven by the driving fan 37 is extracted from the outside at normal temperature through the external port 43 on the return air pipe 11, so as to facilitate the gradual cooling of the liner kit 24 inside the vulcanization box 1, and also facilitate the removal of volatiles in the vulcanization box 1.

[0065] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
