Abstract
The invention relates to a stretching height adjustable curing bladder. The stretching height adjustable curing bladder comprises a curing bladder body, wherein the lower end of the curing bladder body is arranged on a lower chuck which is fixed on a cylinder body of a central mechanism, the upper end of the curing bladder body is arranged in an upper chuck, a piston rod of the central mechanism protrudes through the center of the upper chuck and is provided with an upper ring fixed bolt, and the upper chuck can slide freely on the piston rod. The stretching height adjustable curing bladder is characterized in that at least one removable small copper sleeve is arranged above the upper ring fixed bolt, and a limit bolt is arranged at the top of the piston rod. The stretching height adjustable curing bladder provided by the invention is simple in structure and convenient to adjust, the demolition of the curing bladder body and the upper piston of the central mechanism can be prevented when the stretching height of the curing bladder body is adjusted, the production cannot be affected, and the damage on the equipment cannot be caused.
Description
Technical field
The present invention relates to a kind of curing bag, specifically a kind of adjustable for height curing bag that stretches, belongs to sulphidizing eqmpment technical field.
Background technology
In Type B vulcanizer, after on new curing bag, board uses, along with being on the increase of curing cycle number of times, after the repeated dilation of curing bag, its section girth and external diameter increase.Now, if do not increased the stretching height of curing bag accordingly, curing bag will shrink bad before dress tire, and capsule can be made to scrape tyre bead, pollutes tyre bead, causes finished product tire tyre bead starved breach.
The stretching height of curing bag is that the height of being had by oneself by the height of copper sheathing 3 lower in central mechanism of vulcanizing machine (see Fig. 1) and central mechanism of vulcanizing machine itself determines.The conventional method of present adjustment curing bag stretching height is the height of the lower copper sheathing 3 of adjustment, will stop production like this and remove curing bag and central authority upper piston 2, changes lower copper sheathing 3 accordingly.So not only affect production efficiency, and cause sealing ring to damage when removing curing bag and central authority upper piston 2, production cost is increased.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of adjustable for height curing bag that stretches is provided, its structure is simple, easy to adjust, can when adjusting curing bag and stretching highly, avoid removing curing bag and central authority upper piston, do not affect production, and can not device damage be caused.
According to technical scheme provided by the invention: stretch adjustable for height curing bag, comprises capsule body, described capsule body lower end is arranged on lower chuck, and lower chuck is fixed on the cylinder body of central authority; Described capsule body upper end is arranged in upper chuck, and be provided with pressed on ring gim peg after the piston rod of central authority stretches out from the center of upper chuck, upper chuck can be free to slide on the piston rod; It is characterized in that: be provided with at least one dismountable little copper sheathing above described pressed on ring gim peg, described piston rod part is provided with caging bolt.
As a further improvement on the present invention, described little copper sheathing quantity is 3 ~ 4, and little copper sheathing height is 10 ~ 15cm.
compared with prior art, tool has the following advantages in the present invention:
(1), structure of the present invention is simple, easy to adjust, greatly reduces adjustment curing bag and stretches the time highly used, increase production efficiency.
(2), the present invention adjust curing bag stretch height time, avoid removing curing bag and central authority upper piston, the damage of equipment corresponding site sealing ring can not be caused, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of central mechanism of vulcanizing machine.
Fig. 2 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 2, the adjustable for height curing bag of the stretching in embodiment mainly comprises capsule body 5, and described capsule body 5 lower end is arranged on lower chuck 6, and lower chuck 6 is fixed on the cylinder body 4 of central authority; Described capsule body 5 upper end is arranged in upper chuck 7, and be provided with pressed on ring gim peg 8 after the piston rod 1 of central authority stretches out from the center of upper chuck 7, upper chuck 7 can be free to slide on piston rod 1; Be provided with at least one dismountable little copper sheathing 9 above described pressed on ring gim peg 8, described piston rod 1 top is provided with caging bolt 10.
In the present invention, described little copper sheathing 9 quantity is 3 ~ 4, and little copper sheathing 9 is highly 10 ~ 15cm.
During embody rule, when curing bag use to increase after certain number of times stretch height time, only need the height requirement regulated as required to take off the little copper sheathing 9 of respective heights, take down how high little copper sheathing 9, just how high increase is for the stretching height of curing bag.
Claims (2)
1. stretch adjustable for height curing bag, and comprise capsule body (5), described capsule body (5) lower end is arranged on lower chuck (6), and lower chuck (6) is fixed on the cylinder body (4) of central authority; Described capsule body (5) upper end is arranged in upper chuck (7), and be provided with pressed on ring gim peg (8) after the piston rod (1) of central authority stretches out from the center of upper chuck (7), upper chuck (7) can be free to slide on piston rod (1); It is characterized in that: described pressed on ring gim peg (8) top is provided with at least one dismountable little copper sheathing (9), and described piston rod (1) top is provided with caging bolt (10).
2. the adjustable for height curing bag that stretches as claimed in claim 1, is characterized in that: described little copper sheathing (9) quantity is 3 ~ 4, and little copper sheathing (9) is highly 10 ~ 15cm.
