    Zum Vulkanisieren von Luftreifen werden die Reifenrohlinge in mit Vulkanisationsformen ausgestatteten Pressen über eine bestimmte Zeit mittels eines Heizmediums ausvulkanisiert. Damit die Vulkanisationszeit nicht mehr fest eingestellt und demzufolge in vielen Fällen vorsorglich länger als erforderlich gewählt werden muß, soll die jeweils in den Reifenrohling eingebrachte Wärmemenge ermittelt und der Vulkanisationsvorgang beendet werden, sobald die erforderliche Vulkanisations-Gesamtwärmemenge erreicht ist. Dazu werden in zeitlichen Abständen die Temperaturen an der Vulkanisationsform, an den Heizmedienleitungen für den Hohlraum des Reifenrohlings sowie die Rohlingsanfangstemperatur gemessen, daraus anhand von durch Versuchsheizungen ermittelten, für den betreffenden Vulkanisationsvorgang charakteristischen Temperaturverläufen - beispielsweise mittels einer Rechnersteuerung―die in den Reifenrohling eingebrachte Wärmemenge ermittelt und davon abhängig die Heizzeit gesteuert. Zur Anwendung kommen können unterschiedlich ausgebildete Vulkanisationsformen, die mit und ohne Heizbalg arbeiten, insbesondere mittengeteilte Vulkanisationsformen mit oberer und unterer Halbschale bzw. Vulkanisationsformen, die aus Formsegmenten und Formseitenteilen aufgebaut sind.

    . The invention relates to the manufacture of pneumatic tires and is intended for the vulcanization of their tires in heated molds.
    The aim of the invention is to improve the quality of the tires by preventing overheating or underheating of the tires in the vulcanization process due to temperature fluctuations of the heat transfer media.
    Fig. 1 schematically shows a vulcanization press with two molds for vulcanizing tires by the proposed method; in fig. 2 - temperature curves of the blanket in the last curing zone, obtained during trial heating; in fig. 3 is a diagram of the temperature variation in the wall of the tire from the diaphragm to the mold during trial heating; 4 is the same for a steady state t.
    The method of vulcanization of tires pneumatic tires as follows.
    Pokrush 1 blanks from table 2 are loaded into molds 3 and 4 of a vulcanization press. Each mold consists, for example, of heated top 5 and bottom 6 parts and a central segment part 7. The desalting of tires is carried out with the help of elastic diaphragms 8. The heat carrier is fed into the top 5 and bottom 6 parts of the molds. pipelines 9, to the central parts 7 - through pipeline 10, to diaphragm 8 - through pipeline 11. The removal of coolants from the upper 5 and lower 6 parts is carried out through pipelines 12 and 13, from the middle parts 7 - through pipelines 14 and 15, from diaphragm B through pipelines 16 and 17.
    After closing the molds. 3 and 4 and supplying heat carriers through pipelines 9, 10 and 11 of the tire blanks 1 they are subjected to vulcanization when heat is applied to their outer and inner surfaces. The end of vulcanization is controlled by comparing the current values of the selected criteria for determining the optimal vulcanization of the tire with specified using a computer (not shown) when measuring the temperature of the workpiece tire 1 on the table 2. As a criterion for determining the optimal vulcanization of the tire, choose the amount received during the process of vulcanization of heat, the current values of which are measured continuously in the process of vulcanization in 1-6 seconds. In this case, the measurement of the amount of heat is made on the basis of the temperature of the heat transfer media supplying heat to the outer and inner surfaces of the tire, which are determined by the temperature of the coolant, respectively, at the entrance to the mold and the cavity of the tire. In the process of vulcanization, the current values of the temperature of the coolants at the entrance to the mold and the cavity of the tire and the exit from them are compared with their given values. If the current values deviate from the preset values, the alarm signal is turned on and the vulcanization process is interrupted, which allows to eliminate the damage during the vulcanization process and to eliminate the production of defective tires. The following measurement points using sensors are used to control the control device associated with the computer (not shown): 18 — heat carrier input — hot steam into the diaphragm, 19 and 20 — heat carrier output from the diaphragm, 21 — heat carrier input the central parts of the 7 molds, 22 and 23 - the output of the coolant from the central parts of the 7 molds, 24 - the input of the coolant in the upper 5 and lower 6 parts of the molds, 25 and 26 - the output of the coolant, from the upper and lower parts of the npecc - forms, 27 - temperature of the blank tires 1 on the table 2 (phg.1). The location of these points can also be used for molds of a different design, regardless of whether heat is supplied to the inner surface of the tire with or without a diaphragm. Since the individual zones of the tire are heated differently and at different speeds, the measured value of the amount of heat is compared with the target value of the amount of heat required for the final vulcanization of the last-vulcanizing tire, i.e. critical place. Moreover, this critical place and a predetermined amount of heat are determined by means of test vulcanization and are introduced into a computer as the main control parameter for the type of tires being vulcanized. As can be seen from FIG. 2, the critical place of the tire has the smallest growth tempera313
    tours, shown by curve V. for inner surface of tire, curve Vn for wall of roll, and curve V. - for external surface of tire. The temperature curves for the inner and outer surfaces of the tire approximately correspond to the temperature of the outer surface of the diaphragm and the inner surface of the mold, respectively. During vulcanization from the diaphragm 8, the tire is heated. The change in the temperature of the latter is shown in Fig. 3 by curves, covering the time interval from the start of vulcanization (tp) after several intermediate points in time (t, tn, ... t) to the steady state t. The temperatures at the critical point are determined by vf —the temperature of the inner surface of the diaphragm B, —the temperature of the outer surface of the diaphragm 8, Vc, —the temperature of the inner surface of the mold, V — the initial temperature of the tire preparation 1 V — established with at the point X. In the cavity of the diaphragm 8, the vapor temperature decreases from V; jj to V (Fig. 4) by the value of the remote control and the mold is heated from the tire and its temperature V increases to the temperature Vp by the value V. The values of the indicated temperatures are measured d tchikami inserted into the parts of the mold. When processing these values, the heat losses arising on the contact surfaces between the outer surfaces of the tire and the tire are taken into account, based on empirical dependencies.
    The vulcanization process of the tire is completed after the amount of heat obtained by the tire in the vulcanization process has reached a value equal to the specified one. As a result, taking into account and evaluating the temperature measurements of the heat transfer media, complete curing of the tire is ensured and its re-vulcanization is prevented, and the quality of the product is negatively affected. In addition, the proposed method is simple to implement, since the measurement of the temperature of the heat transfer media is carried out outside the mold. At the same time, the measurement of the amount of heat is made by the temperatures of the heat transfer media at the inlets to the mold and the diaphragm, and the temperatures of these heat transfer fluids at the output

    from the mold and the diaphragm is used to control the process of vulcanization carried out by the proposed method.
