Description
Technical field
The present invention relates to tyre production technology, be specifically related to a kind of non-inflatable tyre global formationPressure injection method.
Background technology
At present, all more complicated of existing non-inflatable tyre production process, operation substep carries out,Operating time is long, and cost is high, and the service life of tire is short. The meeting of existing tire great majority existsInside adds filler, as name is called a kind of Chinese patent 00241097.4 of non-inflatable tyre,This tire has Tire & Tube double-layer structure. This non-inflatable tyre need to be to inject to fill at internal layerThing, forms through reprocessing, and Tire & Tube phase mutual friction when use has reduced use longevity of tireLife. And for example application number is 20071002383.X Chinese patent, though its disclosed non-inflatable tyreSo regardless of Tire & Tube, but the inside of tire is pore space structure, and hole distribution is not in inside tiresWith local, such structure causes tire pressure-bearing size inhomogeneous, makes tire have different being subject toForce, thus cause the dynamic balancing of tire inhomogeneous, and user can experience and jolt, comfort levelBad. And the hole of inside tires can be with the prolongation of service time, and produce under the effect of pressureGive birth to the phenomenon of subsiding, thereby shortened the service life of tire.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art part and a kind of technique letter is providedSingle, cost is low, take that the place of production is little, the pressure injection method of the non-inflatable tyre global formation of easy control.
According to the pressure injection method of non-inflatable tyre global formation provided by the present invention, comprise followingStep:
1) non-inflatable tyre configuring is manufactured to raw material and put into buffer bin, and stir;
2) pre-Hot-pressed injector to 180 DEG C-190 DEG C;
3) promote press injector pressure to 50Pa-60Pa;
4) adjusting charging rate is 10m/s-20m/s;
5) adjust the dwell time to 2-3min;
6) step 1) in non-inflatable tyre manufacture feed injection and enter press injector, according to defaultPattern initiating task;
7), successively after matched moulds, injection, hot melt, cooling, die sinking, obtain non-inflatable tyre.
The non-inflatable tyre configuring is manufactured to raw material and put into before buffer bin, whether check materialMeet designing requirement, material free from admixture, and ensure material aridity.
The preheat temperature of press injector is 180 DEG C-190 DEG C, and this preheat temperature is the one-tenth according to materialType temperature is set. This temperature has met the temperature that requires of tire production material, and press injector reachesCould effectively material fully be dissolved to this temperature, ensure product density uniformity, to strengthenThe resistance to ag(e)ing of product. If temperature, lower than 180 DEG C, can affect the moulding of tire, density is hadVery large impact, because can not be well-done lower than 180 DEG C of materials, material not exclusively dissolves, meetingThe phenomenon that occurs raw material, causes die feeding inhomogeneous, and tire there will be intermediate void or foamingPhenomenon, density does not reach designing requirement, causes undersaturated condition; If temperature is higher than 190 DEG C,Exceeded the heat resisting temperature of material, material has the possibility being scorched, and can not use.
The pressure of press injector is 50Pa-60Pa, and this is to set according to the requirement of forming materials.Being set to 50Pa-60Pa, is in order to allow press injector have enough motive forces, only in this pressureUnder power scope, can allow material in the situation that dissolving, be injected into smoothly mould. If lower than50Pa, pressure is inadequate, and injection force is inadequate, just the material of ormal weight can not be sent into mould, meetingAffect the density of forming tire, cause product density inadequate, tire construction is comparatively loose, in tireThere is bubble to exist, occur foam state, can not use. If higher than 60Pa, raw material injectsMeasure too greatly, can cause product density too large, make the appearance and size of tire not meet designing requirement,That is to say meeting modification, thereby affect performance, and can damage press injector.
Charging rate is adjusted to 10m/s-20m/s, and charging rate is the design rule according to press injectorCalmly, the performance of the moulding of tire needs and material is set. Can allow material in this velocity intervalIn official hour and space, entering smoothly, fully penetrating of production machine manages and mould. IfLower than 10m/s, charging can cause material insufficient slowly, and moulding is unsaturated, not even moulding;If charging exceedes 20m/s, can cause charging too much.
Dwell time is adjusted to 2-3min. In production process, to carry out pressurize step, on the one handIn order to allow material fully react in equipment pipe, to improve hot strength and the bullet of productProperty; In order to allow material can have sufficient time to fill the space of mould, to ensure on the other handProduct has good outward appearance and a density. Through test for a long time, if while finding pressurizeBetween lower than 2min, packing material can be inhomogeneous, insufficient, unsaturated, density is inadequate, fromAnd affect hot strength and the elasticity of product. If but exceeded 3min, properties of product could be subject to againTo impact.
Preferably, step 1) described in buffer bin be funnel case; Step 1) in take stirring rodStir.
Preferably, described non-inflatable tyre is manufactured raw material and is comprised TPE, and it is suitable to comprise in additionConventional additives and auxiliary material.
Preferably, step 2) in pre-Hot-pressed injector to 185 DEG C.
Preferably, step 3) in promote press injector pressure to 55Pa.
Preferably, step 4) adjustment charging rate is 15m/s.
Preferably, step 5) described in the dwell time be divided into three sections, every period of dwell time is40-50s. Dwell time is divided into three sections, has met the intrinsic flow process of production equipment, also makeMaterial has the time more fully to merge. If dwell time deficiency, the product of working it outLikely there is degree of adhesion and cause not cracking or hot strength, the phenomenon that elasticity is inadequate.
Preferably, described every period of dwell time is 45s.
Preferably, step 6) described in preset mode be automatic mode.
Preferably, step 7) in cool time be 120s.
Technical scheme provided by the present invention can comprise following beneficial effect:
1) the pressure injection method of non-inflatable tyre global formation of the present invention due to adopted from material toThe single process of finished product, completes automatically with an equipment, one man operation, and operation is simple,Technique is special, completes consuming time of shaped article and needs 3min left and right, and power consumption is low, only needs circulationWater does cooling agent, without repeatedly processing, and one-shot forming, operation is convenient, and cost is low, takies productGround is little, can significantly improve output and the quality of product.
2) non-inflatable tyre of producing according to the present invention is one-body molded, crosses circular port,Size is uniformly distributed, and even structure is reasonable, there is no dividing of Tire & Tube, has eliminated between Tire & TubeFrictional force and resistance, good dynamic balance, tire stressed evenly, the effect that lands is strong; And wear-resistingBe not afraid of and roll, do not blow out, ageing-resistant, hot strength is large, and elastic recovery degree is good, experiences all sorts of durable.
3) non-inflatable tyre obtaining according to the present invention is non-maintaining, and comfort level is good, raw material environmental protectionGreen, can recycle and reuse.
