Description
Technical field
The invention is related to a kind of full-automatic sidewall back-wrapping system of All-steel tire two-drum forming machine and its control method, category
In a kind of former on wheel hub sidewall.
Background technology
" sidewall anti-package operation " is a very important step in tire base forming process.All-steel tire introduces China 25 years
Come, tire base is carried out in forming process in two-drum forming machine platform, " sidewall anti-package operation " be unable to do without the participation of operating personnel.
" sidewall ", also known as tire sidepiece glue, is tire sidepiece outermost layer part, and material consists of the glue component of soft formula.
In tire base forming process, former is in tire base process for pressing overall process according to 750 °/S high-speed rotation.Left and right sidewall is covered respectively
Cover on 2 layers of capsule, 3bar compressed air is filled with capsule chamber body and causes capsule to drive sidewall drawn expanded.Sidewall is drawn by capsule
After extending technological requirement height, compressed air in evacuation chamber body in 1 second, the centrifugal force of former high-speed rotation and capsule draw high
Under power double action, 100mm and carcass bonding below sidewall component is integrated, and reserves 100mm working space and enters for turn-up arm
Enter.
" turn-up arm " is stretched as sidewall, the core institution of pressing, using on 5bar Action of Wind pressure to sidewall, by servo electricity
Machine travel footpath is drawn back operation, coordinates the high-speed rotation of assembly drum and tire base, complete jointly the circumference on sidewall, the stretching of radial direction and
Bonding operation.
In turn-up arm operation process, need two human hand held rod waxs to be aided in, can just smoothly complete above-mentioned operation.Reason master
If the shearing force between turn-up arm and sidewall, the presence of sliding friction problem, artificial waxing is needed to be alleviated.
The sidewall anti-package operation of artificial waxing auxiliary has problems with：
1st, personnel participate in waxing operation in small space, equipment high-speed rotation state, there is potential safety hazard；
2nd, personnel participate in waxing operation process in, to sidewall freely stretch produce interference, sidewall sizing material thickness direction,
The distribution of width produces deviation with Theoretical Design；
3rd, personnel participate in waxing operation so that labour intensity increases, and personnel's efficiency reduces；
4th, wax powder is brought in sulfurizing mould in the form of adhering to, and produces mold fouling, increases the frequency that dry ice clears up mould,
Increase cost.
Content of the invention
