Description
Изобретение относитс к области изготовлени пневматических шин и предназначено дл вулканизации покрышек пневматических шин с использованием индукционного нагрева.The invention relates to the manufacture of pneumatic tires and is intended for the vulcanization of pneumatic tires tires using induction heating.
Известна пресс-форма дл вулканизации покрышек пневматических шин, содержаша две полуформы, индукционную катушку, снабженную средствами дл соединени с источником СВЧ-энергии, и систему парового нагрева с выполненными в полуформах по периметру их формуюших гнезд каналами 1.A known mold for vulcanizing tires of pneumatic tires, containing two mold halves, an induction coil equipped with means for connecting to a microwave energy source, and a steam heating system with channels 1 formed in the mold halves around the perimeter of their forming nests.
В указанной пресс-форме полуформы выполнены из диэлектрического материала и нагрев ее осуществл етс -паром, а индукционна катушка предназначена дл создани в металлических прослойках покрышки электромагнитного пол высокой частоты, энерги которого выдел етс в этих сло х покрышки в виде тепла, за счет чего и происходит нагрев внутренних слоев покрышки.In this mold, the mold half is made of a dielectric material and is heated by a vapor, and the induction coil is designed to create a high-frequency electromagnetic field in metal layers of the tire, the energy of which is released in these layers of tire as heat, due to which the inner layers of the tire are heated.
Недостатком указанной пресс-формы вл етс больша энергоемкость.The disadvantage of this mold is high energy intensity.
Известна также пресс-форма дл вулканизации покрышек пневматических шин, содержаша две .металлические кольцевые полуформы и систему индукционного нагрева со средствами дл соединени с источником переменного тока 2.A mold for vulcanizing tires of pneumatic tires is also known, containing two metal ring half molds and an induction heating system with means for connecting to an alternating current source 2.
В известной пресс-форме к источнику тока подключаютс сами полуформы, вслед5 ствие чего суш,ествл етс их равномерный индукционный нагрев, а следовательно, и вулканизуемой покрышки.In the known mold, the half-molds themselves are connected to the current source, as a result of which sushi, their uniform induction heating, and consequently, the vulcanizable tire, is used.
Однако поскольку толшина покрышки в зонах протектора, боковин и бортов различна, при равномерном нагреве полуформ будет либо недовулканизаци протектора, либо перевзлканизаци боковин, что отрицательно вли ет на качество покрышек и приводит к непроизводительным затратамHowever, since the thickness of the tire in the tread, sidewalls and sides is different, with uniform heating of the molds, there will either be a lack of vulcanization of the tread or re-vulcanization of the sidewalls, which negatively affects the quality of the tires and leads to overhead costs

Целью изобретени вл етс повышение качества вулканизации покрышек и снижение энергозатрат. Дл достижени поставленной цели вThe aim of the invention is to improve the quality of vulcanization of tires and reduce energy costs. To achieve this goal in
20 пресс-форме дл вулканизации покрышек пневматических шин, содерл ащей две металлические кольцевые полуформы и систему индукционного нагрева со средствами дл соединени с источником переменного20 a mold for vulcanizing tires of pneumatic tires containing two metal ring half molds and an induction heating system with means for connecting to a variable source
