Description

Technical Field

[0001] The present invention relates to the technical field of vulcanized rubber equipment, and particularly to a tire vulcanizer. Background Art

[0002] As is well known, a vulcanizer is a tire vulcanization device. In the mold opening and closing process of the vulcanizer, the vulcanization mold is fixed on the crossbeam, and then the opening and closing movement between the upper mold and the lower mold is realized through the mold opening and closing drive mechanism. In the past several mainstream structures of the vulcanizer, there are mainly two types of drives for the frame mold opening and closing system. One is that the motor drives the worm and worm gear reducer to drive the crank gear to rotate, thereby driving the connecting rod to drive the crossbeam to move up and down and rotate or translate. However, this type of drive often has large driving parts and is limited by the machining accuracy, so the accuracy of the action is often not high. The other is that the hydraulic cylinder drives the crossbeam to lift. Although the accuracy is high, there is a risk of hydraulic oil leakage, and there are slight defects in the action smoothness and synchronism. At the same time, the speed has a limit. In addition, during the lifting process of the crossbeam, when the oil cylinder connecting rod or the crank connecting rod breaks, the crossbeam and the mold mounted on the crossbeam will fall, posing a great safety hazard.

[0012] The tension member 10 is a tension spring. The anti-falling assembly 7 further includes an anti-falling seat 31. A spring support 32 and an anti-falling support 33 are fixed on the anti-falling seat 31. One end of the tension member 10 is connected to the spring support 32 through a first headless pin 34.

Then, the upper die assembly 2 can move up and down through the guiding wheel 52 in the guiding groove 48. That is to say, the upper die assembly 2 can move vertically up and down along the column 12, and can play a guiding and limiting role through the rolling contact between the auxiliary limiting wheels 53 and the guiding plate 46. A gap is left between the guiding frame 47 and the guiding plate 46.

[0014] A through hole 54 is formed on the anti-falling seat 31. A guiding rod 55 passing through the through hole 54 is provided on the base 11 corresponding to the position of the through hole 54; the lower part of the guiding rod 55 is connected to the base 11 by sequentially sleeving an inner eccentric sleeve 56 and an outer eccentric sleeve 57. After the upper die assembly 2 descends a certain distance, the through hole 54 on the anti-falling seat 31 will pass through the guiding rod 55, which can ensure the coaxial accuracy of the upper die 15 and the lower die 19 within the die adjustment range of the tire vulcanizer and reduce processing redundancy.

[0015] The tire vulcanizer further includes an extreme safety component 58, and the extreme safety component 58 includes a connecting seat 59 and a safety cylinder 60.

The bolt 62 passes through the connecting seat 59 and is inserted into the jack 63.

[0016] The tire vulcanizer further includes a mold clamping component 64 for locking or unlocking the upper mold component 2; the mold clamping component 64 includes oppositely arranged mold clamping screws 65 and mold clamping sleeves 66. The mold clamping screws 65 are installed on the cross beam 16. A tooth-shaped lock head 67 is installed at the bottom end of the mold clamping screw 65. The mold clamping sleeves 66 are installed on the base 11. A lock groove 68 corresponding to the lock head 67 is provided on the mold clamping sleeve 66; a contact rod 69 is installed on the mold clamping screw 65. A detection seat 70 is installed on the base 11 on one side of the mold clamping sleeve 66. A travel switch 71 capable of contacting the contact rod 69 is installed on the detection seat 70; the lower part of the mold clamping sleeve 66 penetrates through the base 11 and is fixedly connected to a second connecting rod 72. A mold clamping cylinder 73 is installed on the bottom surface of the base 11. The front end of the piston rod of the mold clamping cylinder 73 is connected to a third connecting rod 74 through a shaft. The third connecting rod 74 is fixedly connected to a transmission rod 75. The second connecting rod 72 is rotatably connected to the transmission rod 75.

[0017] In the embodiment of the present invention, there are 4 mold clamping screws 65 and 4 mold clamping sleeves 66. The 4 mold clamping screws 65 are respectively installed at the four ends of the cross beam 16, and the 4 mold clamping sleeves 66 are respectively installed at the four ends of the base 11. There are two mold clamping cylinders 73. The mold clamping sleeves 66 are in groups of two, and are driven in cooperation with the same mold clamping cylinder 73 and the transmission rod 75 to achieve linkage.

[0018] The tire vulcanizer can realize a single mold opening and closing process, and can also realize a double mold opening and closing. When it is necessary to realize a double mold opening and closing, the same base 11 can be shared, and the same structure is set on the base 11 to realize the mold opening and closing process. In the embodiment of the present invention, for the convenience of explaining the mold opening and closing process, taking the realization of double mold opening and closing as an example, that is, there are two sets of mold opening and closing on the left and right, and the left and right actions are independent, and tires of different specifications and different cycles can be produced, improving the production efficiency, and the different working states of opening and closing between the upper mold component 2 and the lower mold component 3 are shown in the figure.

[0019] The specific working principle of the present invention is as follows: Driven by the servo drive motor 5, when it stops during the lifting process, the servo drive motor 5 stops working and brakes, and the upper die assembly 2 will stop at the middle position, improving the action response and action accuracy, and enhancing the working stability and synchronism. That is, the servo drive motor 5 drives the reducer 20 to act, and through the coupling 24, it can drive the driving wheel 25 to rotate. Then, the anti-falling assembly 7 and the upper die assembly 2 connected by the flexible connecting member 6 (a chain is used in the embodiment of the present invention) will move up and down along the vertical direction of the column 12 together, and the problem of existing hydraulic oil leakage is also avoided. During the up and down movement, the smooth up and down movement can be realized through the guiding assembly 45, and the guiding and limiting can be further realized through the cooperation of the guiding rod 55 and the through hole 54 on the anti-falling seat 31, which also plays a role of double guiding, making the up and down movement of the upper die assembly 2 more stable; Under normal circumstances, the pulling force of the flexible connecting member 6 on the anti-falling plate 8 is greater than the pulling force of the tension spring, so the anti-falling plate 8 can be kept in a vertical state, and the second protrusion 36 can be prevented from accidentally abutting against the locking groove 44; in the case of the fracture of the flexible connecting member 6, there is no longer the pulling force of the flexible connecting member 6 on the anti-falling plate 8, so the anti-falling plate 8 will be rotated into an inclined state by the pulling force of the tension spring, and the second protrusion 36 will be extended until it abuts against the locking groove 44. That is, once the flexible connecting member 6 breaks, under the action of the pulling force of the tension spring, the anti-falling plate 8 is switched from a vertical state to an inclined state, and the second protrusion 36 can abut against the locking groove 44 on the locking plate 43 to achieve locking, which can prevent the upper die assembly 2 from falling, playing the first layer of anti-falling safety guarantee; at the same time, the limit safety assembly 58 is also provided. That is, when the upper die assembly 2 rises to the limit position or the set position, the safety cylinder 60 acts to extend the bolt 62 until the bolt 62 is inserted into the jack 63 of the column 12, which can ensure that the upper die assembly 2 will not fall, playing the second layer of anti-falling safety guarantee, and also providing a reliable safety guarantee for personnel to maintain under the upper die assembly 2; When the upper die assembly 2 descends and performs the die-closing process with the lower die assembly 3, the lock head 67 on the lock die screw 65 locks into the lock groove 68, and the travel switch 71 will contact the contact rod 69, detecting that the upper die assembly 2 has descended in place. Then the lock die cylinder 73 acts, and through the cooperation of the second connecting rod 72, the transmission rod 75, and the third connecting rod 74, the lock die sleeve 66 can be rotated to lock the lock head 67 and the lock groove 68, realizing the locking of the upper die assembly 2, thus facilitating the subsequent process operation of the tire vulcanizer; when unlocking is required, the lock die cylinder 73 also acts to rotate the lock die sleeve 66 to unlock the lock head 67 and the lock groove 68, realizing the unlocking of the upper die assembly 2.

[0020] In summary, a tire vulcanizer of the present invention has higher action precision and stronger stability, and is equipped with multiple safety guarantees, which can meet the needs of safe production and high-efficiency production.
