Technical field
The present invention relates to a kind of tire production mechanical field; Especially a kind of frame, mounting mechanical arm of tyre, pressing mechanism, vulcanizing chamber and clasp mould mechanism, central authority, segmented mold drive unit, two-position four-point rear inflation apparatus of comprising unloads mechanical arm of tyre and the high-performance radial-ply tyre intelligence vulcanizer that is connected roller-way.
Background technology
Along with rapid development of automobile industry, the automaticity of tyre industry requires increasingly high, and the known more advanced vulcanizer such as the patent No. are: 200920056320.3; Patent name is: high accuracy frame-type hydraulic tyre vulcanizing machine, this device have realized that running noises is low, fault is few, Homes Using TV is high, energy resource consumption is few, die life is long, the production efficiency advantages of higher, yet in the middle of actual invocation procedure; The material loading process of tire is cumbersome, deposits mechanism for tire and often is prone to cause squeegee action, because green tire does not vulcanize; Some plastic flowing can take place, and cause shape to change, under gravity pressure; The sidewall, below is stressed big; So the distortion in rim of the mouth is particularly serious under the green tire,, can produce heterogeneous vulcanization if put into the sulfurizing mould sulfuration to such green tire; Cause tire quality poor, for the quality of tire hides some dangers for.Elevating mechanism adopts general orthoscopic guide frame, often has skew in the lifting process, and precision is not high to the extracting of tire and all influences to some extent in service life of device; Change over to and produce mechanism and realize through pivoted arm mostly, rotate unstable; The pivoted arm buffer gear mainly contains dual mode: a kind of mode is on the manipulator pivoted arm, buffer to be installed, and cushions through collision block at the extreme position of swinging, because the cylinder stroke is long; Cause pivoted arm that little play is arranged, the cushion effect unbalance stress causes certain impact; A kind of in addition mode is buffer to be installed in change on the piston rod that produces cylinder, and and then piston rod moves together, because piston rod is thinner; Stressed less, the tyre catching apparatus quality is big when swinging to extreme position, inertia big, make piston rod produce certain swing distortion, causes the buffering job insecurity; Buffering effect is not good, causes manipulator violent in the vibration of position of rest.For just vulcanizating the tire that needs the inflation cooling and shaping; Inflate the cooling and shaping device after adopting the two-position four-point that automaticity is high, operation is compact, setting accuracy is high, efficient is high mostly, this device adopts a switching mechanism to overturn mostly, thereby raises labour efficiency; But; Present switching mechanism adopts motor as driving mostly, adopts the mode of sprocket wheel chain to carry out transmission, yet; In the process of using, the chain tension degree varies often occurs, cause upset shakiness and the unstable situation in location to occur.
