Description
Technical field
The present invention relates to a kind of forming method of tire, the positive reverse wrap molding method of specifically a kind of giant tyre.
Background technology
There are one the positive and negative job contract skills that important step is exactly carcass material in tyre forming process, especially anti-
In skill of undertaking to perform work within a time limit and according to specifications, most of techniques are all made of capsule to carry out anti-package, but since previous capsule cannot together be rotated with assembly drum,
Carcass material generates abrasion in forming process with capsule because of friction, and the constituent structure proportioning of capsule is bad, causes
In the anti-package technique of tire, the abrasion of reverse-wrapped capsule is larger, and larger pressure is caused to the control of production cost.
In addition, after positive closure, buckle ring is carried out to triangular glue steel-wire ring before anti-package, in traditional buckle ring technique,
Since buckle ring structure is too simple, causes triangular glue steel-wire ring bonding insecure, it is serious to also result in buckle ring component wear.
Also it is exactly, since the manufacturing process of forming machine main spindle and the main shaft of anti-package device is improper and material selection is improper,
It is easy to cause the premature abrasion of main shaft and damage so that the production cost increases.
It is an object of the invention to design a kind of tire moulding method, it reduces the abrasion of reverse-wrapped capsule, reduces button
The abrasion of coil component so that triangle glue bond is secured, reduces the abrasion of main shaft, improves production efficiency, reduces and be produced into
This.

Two, the transmittance process of tyre building machine
In the forming process of steel radial tyre, the transmission of carcass is generally directly transmitted with one group of transmission ring, due to having
Anti-package device, carcass transmission can not directly be clamped from carcass drum 19 and be transmitted on assembly drum.The present invention cleverly solves
This problem.
Using tyre building machine by the first carcass component from carcass drum 19 be delivered to assembly drum the specific steps are：
Step 1, prepare：Tyre building machine, which is integrally located at, waits for position, and anti-package device K is towards carcass drum 19；In support device
Oil cylinder 73 retract, idler wheel 71 is packed up, balance base is left；Later, rotating device J rotates 180 degree so that transmits loop device
Towards carcass drum 19.
Step 2, it is clamped：Oil cylinder 73 in support device stretches out, and so that idler wheel 71 is supported on balance base, tyre building machine court
It is moved to carcass drum 19；When the first carcass component, which is located at, to be transmitted inside loop device, the first carcass transfer device stop motion；It
Afterwards, it transmits loop device and clamps the first carcass component in carcass drum 19.
Step 3, it transmits：Tyre building machine is moved towards assembly drum, after transmitting loop device removal carcass drum 19, support dress
The oil cylinder 73 set is retracted, and idler wheel 71 is packed up, balance base is left；Later, rotating device J rotates 180 degree so that anti-package device
K is towards carcass drum 19；Oil cylinder 73 in support device stretches out, and idler wheel 71 is made to be supported on balance base, tyre building machine towards at
Type drum movement.
Step 4, it discharges：After the first carcass component is nested on assembly drum by transmission loop device, tyre building machine stops
Movement；Later, it transmits loop device and discharges tire base, by the first carcass assembly set on assembly drum.
Step 5, it waits for：Tyre building machine is moved towards carcass drum 19, is moved to and is waited for position.
Three, positive reverse wrap molding technique

Step 1：Carcass assembly set in carcass drum 19；
Step 2；Positive closure is carried out to the both sides of carcass component respectively using the first anti-package device and the second anti-package device；
Step 3：Buckle ring is carried out to the both sides of carcass component respectively using the first anti-package device and the second anti-package device；
Step 4：Retainer is carried out to the both sides of carcass component respectively using the first anti-package device and the second anti-package device；
Step 5：Anti-package is carried out to the both sides of carcass component respectively using the first anti-package device and the second anti-package device；
Step 6：All turn-up process are completed to carcass component, obtain the first carcass component.
2, the positive closure process in the step two includes step 2.1：
The whole axial direction along forming machine main spindle 13 of anti-package device, moves towards carcass drum 19, reaches away from carcass drum 19
When first distance and position, outer sleeve device stop motion；But finger-type sheet devices and device disposed thereon, capsule dress
It sets and device disposed thereon continues on the axial direction of forming machine main spindle 13, moved towards carcass drum 19；At this point, being located at finger-type piece
On finger-type piece 4 rotated along articulated shaft, top scatter；And to wait for that the edge portions of the carcass component of anti-package are placed exactly in
4 inside of finger-type piece.
3, the positive closure process in the step two includes step 2.2, is located at after step 2.1：
Outer sleeve device is moved towards carcass drum 19, and the boosting sleeve 23 and finger-type piece 4 on outer sleeve device contact, and make it
It rotates and collapses around articulated shaft；During gathering, the edge portions of carcass component are pressed against on capsule 8 by finger-type piece.
At this point, finger-type piece 4 collapses, the edge portions of carcass component are clipped between finger-type piece 4 and capsule 8, and with finger
The gathering of shape piece 4 is constantly pressed towards the axis center of forming machine main spindle 13.
4, the buckle ring step in the step three includes：
Triangular glue steel-wire ring is arranged in the end of the clamping jaw 7 of buckle ring driving device 6；Buckle ring driving device 6 pushes clamping jaw
7, triangular glue steel-wire ring is pushed to the setting position of carcass component by clamping jaw 7；Later, driving of the clamping jaw 7 in buckle ring driving device 6
Under, home position is returned to, buckle ring action is completed.
After the above step, outer sleeve device and finger-type sheet devices move one away from the direction of carcass drum 19 simultaneously
Segment distance.
5, the retainer step in the step four includes：
Piston 28 is moved towards carcass drum 19, and then pushes sliding plate 11 axially move closer to carcass drum 19, so that top
Bar 10 rises, and capsule 8 is closely connected on carcass component by the closing piece 9 at 10 top of mandril.
6, the anti-package step in the step five includes：
Capsule 8 inflates spreading, squeezes carcass component upwards and towards carcass drum 19, at the same time, boosting disk 5 is by protuberance
Capsule 8 pushes carcass drum 19 to, and carcass component is reversely coated on the outside of triangular glue steel-wire ring, completes turn-up process.
First anti-package device is the anti-package device K on the first carcass transfer device of 19 side of carcass drum, and second is anti-
Bag apparatus is the anti-package device K ' positioned at 19 other side of carcass drum, and the structure and working method phase of the anti-package device K
Together.
