Abstract
The present invention discloses a full steel engineering radial tire forming process which has the steps that first, a carcass cord cylinder and other parts are jointed according to a smaller diameter phi 2, and then a jointed embryo tire is sheathed on a radial contraction drum, expands the radial contraction drum and drives the carcass cord cylinder to evenly stretch to phi 3; turn down and buckling a steel ring for the carcass cord cylinder are carried out by using a finger-shaped turn down device, pressing in of an apex and bladder turn up of the carcass cord are carried out, and the pressing in is carried out again after other half parts are jointed; finally, the diameter of the radial contraction drum is reduced, at the time, the diameter phi 1 of the radial contraction drum is smaller than the diameter phi 4 of the steel ring, and the shaped embryo tire is unloaded from the radial contraction drum, wherein phi 3 > phi 2 > phi 4 > phi 1. The present invention can ensure that enough height of a drum shoulder is offered to the pressing in of the apex when buckling the ring, and simultaneously, the situation of conventional forming methods that carcass steel wires of the turn down cross and get goffered at the lower part of the steel wire ring when the height of the drum shoulder is adopted is avoided. Moreover, the ratio of sparse and split cords generated in the carcass cord is reduced, which improves product qualification rate and reduces the production cost.
Description
Technical field:
The present invention relates to a radial all-steel engineering tyre forming process, belong to tyre technology.
Background technology:
Radial is a kind of of tire, and is consistent with the meridian section of cord tyre because of its casing ply and circumferential line are 90 ° of angles or arrange near 90 ° of angles, the spitting image of tellurian meridian, so be called radial.Compare with common cross-ply, radial has following advantage: resistance to rolling is little, fuel savings; The tyre surface wearability is good, long service life; Elasticity is big, and resiliency is good; Anti-thorn ability is strong; Adhesive force is big.Therefore compare with conventional tyre and have better use value, but because the complex manufacturing technology of radial, make require high, product percent of pass is lower, causes the cost of radial higher, is unfavorable for promoting the use of radial.
Summary of the invention:
The objective of the invention is to, a kind of full steel engineering radial-type tyre forming process is provided.This technology can improve product percent of pass, reduces production costs.
Technical scheme of the present invention.Full steel engineering radial-type tyre forming process, this technology may further comprise the steps: wherein for Φ 1, Φ 2, Φ 3, Φ 4 following relation is arranged, Φ 3＞Φ 2＞Φ 4＞Φ 1;
A, earlier on a diameter is the drum of Φ 2, carry out the applying of carcass cloth tube, then bonding good bandage is enclosed within radial contraction bulging on; Or directly rouse the applying of carrying out carcass cloth tube on the Φ 2 in radial contraction;
B, expansion radial contraction drum drive the carcass bandage and evenly stretch to Φ 3, make Φ 3＞Φ 2;
C, utilize finger-type just wrapping device the carcass bandage is just wrapped, detains steel ring,
D, carry out the pressing of triangle glue and the capsule anti-package of carcass cord again,
Carry out pressing behind e, other half parts of having fitted; Dwindle the radial contraction drum at last, make the diameter of phi 4 of the radial contraction drum diameter of phi 1 of this moment, the fetus of moulding is drawn off from the radial contraction drum less than steel ring.
In the above-mentioned full steel engineering radial-type tyre forming process, among the described step a, when the radial contraction drum is in diameter of phi 2, can have between the clappers of assembly drum intermittently, but when expanding into diameter of phi 3, the gap between drum should be retracted to minimum as far as possible.
In the aforesaid full steel engineering radial-type tyre forming process, for Φ 1, Φ 2, Φ 3, Φ 4 following relation is arranged, Φ 3 is than Φ 2 big 10 ~ 200mm, and Φ 2 is than Φ 4 big 10 ~ 100mm, and Φ 1 is than Φ 4 little 15mm at least.
In the aforesaid full steel engineering radial-type tyre forming process, among the described step a, for making the even extension of carcass cord, the surface of radial contraction drum clappers has antiseized coating or surface to increase universal ball is arranged.
Compare with prior art, the present invention utilizes same assembly drum to adopt the moulding process of diameter change, the bandage diameter when making the carcass cord applying diameter of tire just wrap and buckle circle less than cord.This technology has solved bulging shoulder height degree and the carcass cord is just wrapping pleating contradiction, when not only having guaranteed the button circle triangle glue be fitted with enough bulging shoulder height degree, cause when having avoided the conventional forming method to adopt this drum shoulder height to spend again simultaneously and just wrap the carcass steel wire in wire loop bottom intersection and pleating situation.Simultaneously since cord fabric ply-up diameter of phi 2 greater than steel ring diameter of phi 4, can reduce the radially extension rate of carcass bandage, the reduction of radially extension rate can reduce the carcass cord and produce rare line and the ratio that bursts at the seams, further improved product qualification rate, reduced production cost.
Description of drawings:
Accompanying drawing 1～5 is an enforcement schematic diagram of the present invention;
The specific embodiment:
Embodiment.The present invention adopts the radial contraction drum that can change diameter to carry out tire building, the radial contraction drum can be radially expanded and shrink, its diameter is less than the diameter of phi 4 of steel ring when shrinking fully, gap when being expanded to Φ 3 between clappers should be as far as possible little, preferably very close to each other, can avoid doubling material when carrying out the cord anti-package like this.Expand into Φ 3 owing to need to drive the carcass bandage from Φ 2 simultaneously, therefore require the surface of radial contraction drum clappers to make particular processing, as adopt the mode of special release coating or the universal ball of surface increase to realize, only in this way could guarantee the even extension of carcass cord.Concrete steps of the present invention are as follows:
Earlier carry out the applying of carcass bandage and miscellaneous part according to 2 pairs of tires of diameter of phi, this step can be carried out on other drum, also can directly on the radial contraction drum, carry out, during as applying carcass bandage on other drum, need the fetus that posts is enclosed within on the radial contraction drum, and radial contraction drum is expanded, drive the carcass bandage and evenly stretch to Φ 3 (Φ 3＞Φ 2), the bandage diameter when making the carcass cord applying diameter of tire just wrap and buckle circle less than cord; Utilize finger-type just wrapping device the carcass bandage is just wrapped, detains steel ring, carry out the pressing and the carcass cord capsule anti-package of triangle glue again, after the capsule anti-package was finished, other half parts of fitting carried out pressing then; Dwindle the radial contraction drum at last to diameter of phi 1, make the diameter of phi 4 of the radial contraction drum diameter of this moment, the fetus of moulding is drawn off from the radial contraction drum less than steel ring.Expand into Φ 3 owing to need to drive the carcass bandage from Φ 2,, can do specially treated, increase preventing viscosity step, as adopt antiseized coating or surface to increase universal ball and carry out antiseized the surface of radially shrinking the drum clappers for guaranteeing the even extension of carcass cord.According to the difference of tire specification, choosing of 4 diameters can be different, but following relation: Φ 3 is roughly arranged than Φ 2 big 10 ~ 200mm, and Φ 2 is than Φ 4 big 10 ~ 100mm, and Φ 1 is than Φ 4 little 15mm at least.
