Description
Technical field
The utility model relates to tire building machinery field, specifically tire building operation tyre surface press-roller device.
Background technology
As everyone knows: the tyre surface of tire cans be compared to the sole of leather shoes, is the Focusing on components directly contacted with ground.Tyre surface pressing technology, just as being solid being pressed together on shoes of sole that coats glue, is the key technology of guaranteeing that tire tread is solid, durable.
The press bonding roller that current tyre surface pressing technology adopts is narrow limit pressure roller, relies on the whole pressing process that completes tyre surface with the rotation of tire that moves axially of pressure roller.This pressing is narrower because of pressure roller, so in the time of in the middle of the pressing tyre surface, tyre surface limit section (tire shoulder position) is because of without active force, there will be the perk phenomenon, and when isobaric roll-in is bonded to this position (tire shoulder), need to increase pressing pressure and pressing time and just can guarantee the pressing quality, thereby pressing occurs excessively and the drawback of time waste.In pressure roller shaft, in moving process, because pressure roller is narrow, pressure is large and it is slow to move axially, so can produce certain pressure of axially catching up with to tyre surface, cause tread mix to have the drawback concentrated to the tire shoulder position.
Summary of the invention
The purpose of this utility model just is to overcome the deficiencies in the prior art, and a kind of tire building operation tyre surface press-roller device is provided, and improves the pressing efficiency of tyre surface, and what is more important has promoted the pressing quality of fetus tire shoulder.
The utility model adopts following technical solution: a kind of tire building operation tyre surface press-roller device, be provided with rear pressure roller, it is characterized in that, the roll shaft of rear pressure roller is connected with the expansion link of cylinder, the cylinder body of cylinder is pressed on dolly after support is fixed on, and rear pressure dolly is arranged on rear pressure slideway, on rear pressure dolly, through fixed support, another cylinder is installed, the cylinder piston rod of another cylinder is connected with the precompressed roll shaft through fixed mount, is set with two pony presses on the precompressed roll shaft.
The utility model also can be achieved by the following measures: the outline of pony press matches with the outline of the tyre surface of pressing.Cylinder piston rod is downward-sloping, and its extended line is by the fetus center of circle.Precompressed roll shaft two ends are arranged on fixed mount through bearing.
The beneficial effects of the utility model are, simple in structure, improve the pressing efficiency of tyre surface, and what is more important has promoted the pressing quality of fetus tire shoulder.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is the utility model pony press.
1. rear pressure rollers in figure, 2. pony press, 3. bearing, 4. fixed mount, 5. cylinder piston rod, 6. fixed support, 7. cylinder, 8. fixed support, 9. rear pressure dolly, 10. rear pressure slideway, 11. cylinders, 12. supports.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, to help understanding content of the present utility model.
As shown in Figure 1 and Figure 2, the utility model is provided with rear pressure roller 1, the roll shaft of rear pressure roller 1 is connected with the expansion link of cylinder 11, the cylinder body of cylinder 11 is pressed on dolly 9 after support 12 is fixed on, rear pressure dolly 9 is arranged on rear pressure slideway 10, through fixed support 8, another cylinder 7 is installed on rear pressure dolly 9, cylinder 7 is arranged on fixed support 8 through fixed support 6, the cylinder piston rod 5 of another cylinder 7 is connected with the precompressed roll shaft through fixed mount 4, precompressed roll shaft two ends are arranged on fixed mount 4 through bearing 3, cylinder piston rod 5 is downward-sloping, and its extended line is by the fetus center of circle.Be set with two pony presses 2 on the precompressed roll shaft, pony press 2 overall sizes need be processed according to the fetus specification, and the outline of pony press 2 matches with the outline of the tyre surface of pressing.Rear pressure slideway 10 is fixed in ground.Rear pressure dolly 9 can be on rear pressure slideway 10 long distance moving by setup program, pony press 2 carries out short distance with cylinder piston rod 5 by the program set and stretches, exerts pressure.
After tyre surface pressing step starts:
(1) after, press dolly 9 to move to tyre surface pressing start bit by rear pressure slideway 10, rear pressure roller 1 is depressed and is started to exert pressure in the confession of cylinder 11, and changes axially operation of position by the pressing start bit to pressure.
(2), after after, pressure roller 1 is pressure bonded to pressure variation position, pony press 2 follow procedures are set and are provided pressure to start to exert pressure by cylinder 7.Rear pressure roller 1 continues to change position by pressure and carries out pressing to tire shoulder stop bits follow procedure track.
(3) after after, pressure roller 1 is caught up with and is depressed into the tire shoulder stop bits, pony press 2 follow procedure under the drive of cylinder 7 is set and is regained, and rear pressure roller 1 continues to catch up with pressure, until the edge stop bits completes whole tyre surface pressing.
Claims (4)
1. a tire building operation tyre surface press-roller device, be provided with rear pressure roller, it is characterized in that: the roll shaft of rear pressure roller is connected with the expansion link of cylinder, the cylinder body of cylinder is pressed on dolly after support is fixed on, rear pressure dolly is arranged on rear pressure slideway, through fixed support, another cylinder is installed on rear pressure dolly, the cylinder piston rod of another cylinder is connected with the precompressed roll shaft through fixed mount, is set with two pony presses on the precompressed roll shaft.
