The specific embodiment
As shown in Figure 1 to Figure 3, green tyres combined pressure roller mechanism arrangement comprises frame 1, in frame 1, be provided with anti-package pressing roll mechanism 2, tyre surface pressing roll mechanism 4, tire shoulder pressing roll mechanism 3, three is upper, middle and lower distribution on vertical, all have the running roller that is arranged on front end, running roller rear end is provided with is sent into the roll extrusion station contacting with fetus outer surface the driving mechanism of implementing roll extrusion operation.
As shown in Figure 1, fetus combined pressure roller device comprises two cover anti-package pressing roll mechanisms, is responsible for respectively roll extrusion tyre surface both sides and tire shoulder position, i.e. the B region of the fetus left and right sides; A set of tyre surface pressing roll mechanism 2 is responsible for ，Ji a-quadrant, roll extrusion tyre surface position; Two cover tire shoulder pressing roll mechanisms 3, are responsible for respectively roll extrusion tire shoulder inner side and position, sidewall, i.e. the C region of the fetus left and right sides.
The pressure roller of tire shoulder pressing roll mechanism 3 has wider axial length, and its length and outer surface profile line match with the outer wheels profile of a-quadrant, guarantees that whole a-quadrant can be subject to the uniform pressure force of running roller in rolling process.The running roller of tire shoulder pressing roll mechanism 3 outer wheels profile along C region in rolling process moves, in moving process, make whole C region all be subject to the more uniform pressure force of pressure roller, wherein this running roller is realized along the mode that moves through air cylinder driven of C region contour line.For anti-package pressing roll mechanism 2, because the curvature in B region is larger, use air cylinder driven, the movement locus of running roller is difficult to coupling with B region exterior outline line, so during the outer surface of running roller roll extrusion B region, the discontinuity in B region, affects tire quality.For overcoming this shortcoming, anti-package pressing roll mechanism 2 adopts the servo-drive of being controlled by PLC system, controls in real time the driving force of servo-actuating device by PLC program is set, and the movement locus of rolling process middle roll, realizes profiling roll extrusion.The preferred electric cylinder of this servo-actuating device, the structure shown in anti-package pressing roll mechanism 2 preferred figures 4, specific as follows:
There are left and right two cover anti-package pressing roll mechanisms 2, every cover anti-package pressing roll mechanism 2 all comprises running roller 21, rotation driving mechanism 23, the preferred servo electric cylinder of rotation driving mechanism 23, is pivotally connected part 24 and the rectilinear motion of servo electric cylinder is converted into the rotation campaign of running roller 21.Pivot connector 24 comprises pivotally connected plate 241, rotating shaft 242, and one end of pivotally connected plate 241 connects the output of servo electric cylinder, and the other end connects running roller 21, and when the cylinder rod of servo electric cylinder stretches out or retracts, running roller 21 is done rotation campaign around rotating shaft 242.Rotation driving mechanism 23, pivot connector 24 are arranged on link 25, and this link 25 is connected with radial drive mechanism 22, and this radial drive mechanism 22 comprises radially cylinder 221.Radially cylinder 221 and link 25 are arranged on slide plate 264, are provided with radially slide rail 222 on slide plate 264, and under the effect of cylinder 221 radially, connecting plate 25 radially slide rail 222 slidably reciprocates.
While implementing roll extrusion operation, radially the cylinder rod of cylinder 221 stretches out forward, drives connecting plate 25 radially on slide rail, to fetus direction, sliding, until running roller 21 arrives and the position of fetus pressure contact; Then the cylinder rod of rotation driving mechanism stretches out, and does rotation campaign under the effect of pivot connector 24, and its rotation track is basically identical with the outline line in B region.Meanwhile, green tyres rotates on assembly drum, thereby makes the whole B region of fetus can be subject to the pressing effect very uniformly of running roller 21.
Anti-package pressing roll mechanism 2 also can adopt following structure: remove slide plate 264, only use connecting plate 25, radially cylinder 221, rotation driving mechanism 23, pivot connector 24 are all arranged on connecting plate 25, radial drive cylinder 221 is connected with rotation driving mechanism 23, rotation drives cylinder 23, pivot connector 24 to be slidably connected with connecting plate 25, is driving acting on connecting plate 25 of cylinder 221 to slide and realize turnover roll extrusion station.
Because left and right anti-package pressing roll mechanism 2 is used for respectively the B region of roll extrusion fetus arranged on left and right sides, tire for different size, horizontal (axially) distance in arranged on left and right sides B region is different, for improving the versatility of this combined pressure roller device, this device is provided with adjusting device 26, regulates driving mechanism 27, and the two is all arranged in frame 1.Adjusting device 26 comprises axial slide rail 261, ball-screw 262, screw 263, regulates driving mechanism 27 to comprise motor 271, regulating wheel 272, Timing Belt 273, synchronous pulley 274.The output of motor 271 is connected with synchronous pulley 274 by Timing Belt 273, drives synchronous pulley 274 to rotate, and is also provided with for regulating the regulating wheel 272 of Timing Belt 273 expanding forces in frame 1.Synchronous pulley 274 is fixedly connected with ball-screw 262, the screw thread of left and right two groups of opposite directions is set on ball-screw 262, left and right screw thread place arranges left and right two screws 263, and left and right screw 263 is connected with the slide plate 264 on left and right anti-package pressing roll mechanism 2 respectively.In frame 1, be provided with two groups of axial slide rails 261, slide plate 264, across two groups of axial slide rails 261, is slidably connected with axial slide rail 261.
When tire specification increases, the lateral separation in arranged on left and right sides B region increases, now need to adjust the distance between left and right anti-package pressing roll mechanism 2, two axial distances between running roller 21 are increased, can realize by the following method: motor 271 drives synchronous pulley 274 to rotate, ball-screw 262 is rotated, by the left and right screw of screw thread transmission, on ball-screw 262, move in opposite directions, thereby drive left and right anti-package pressing roll mechanism slide rail 261 slide in opposition vertically, when the distance between the two reaches preset value, motor 271 stops operating.When tire specification reduces, motor 271 reversions.
While using this combined pressure roller device to implement roll extrusion operation, anti-package pressing roll mechanism 2, tire shoulder pressing roll mechanism 3, tyre surface pressing roll mechanism 4 extend out to forward roll extrusion station simultaneously, the zones of different of fetus are implemented to roll extrusion simultaneously.Different demands according to each roll extrusion region to the roll extrusion time, three can exit roll extrusion station at different times, stops roll extrusion.
