Abstract
Dispozitiv de etirare-calibrare a tuburilor termocontractabile din PVC rigid, caracterizat prin aceea ca, în scopul obtinerii acestor tuburi în flux continuu prin însurubare într-un ax central ce se fixeaza prin însurubare într-un dorn al capului de extrundere pe ax montîndu-se, în ordine un prim grup de role stabilizate a diametrului tubului extrus montate pe patru siruri diametral opuse, astfel ca diametrul cercului de înfasurare a extremitatilor lor sa fie egal cu diametrul interior al tubului extrus, apoi un al doilea grup de role de etirare si calibrare montate, de asemenea, pe patru siruri diametral opuse si în doua zone, astfel ca pe prima zona, de etirare a grupului, extremitatile rolelor sa fie dispuse dupa un con crescator în diametru pîna la cea de a doua zona de calibrare unde diametrul cilindrului înfasurator al extremitatilor rolelor al extremitatilor rolelor sa fie pusin mai mare decat diametrul interior al tubului etirat, atît primul grup de role de stabilizare cît si cel de al doilea grup de role de etirare si calibrare avand posibilitatea de a se roti liber pe ax, în continuare este dispusa o rola de ghidare de forma mica dispus înspre grupul de role element, de preaplatisare a tubului executat dintr+o banda metalica, avand forma literei U fixata de ax la mijlocul ei, cu ajutorul unor piulite si dispusa cu cele doua brate înspre exterior.Device for calibration of rigid PVC heat-shrinkable tubes, characterized in that in order to obtain these tubes in continuous flow by screwing them into a central shaft which is fixed by screwing into a pin of the extrusion head on the axle being mounted , in order, a first group of stabilized rollers of the diameter of the extruded tube mounted on four diametrically opposite struts, such that the diameter of the ending circle of their extremities is equal to the inner diameter of the extruded tube, then a second group of rolls of calibration and calibration also mounted on four diametrically opposite struts and in two zones, such that on the first group ejection zone, the recesses of the rollers are disposed after an increasing cone in diameter to the second calibration zone where the diameter of the roller of the roll edge extremities being greater than the inner diameter of the etiquette tube, the first set of stable rollers and the second group of ejection and calibration rollers having the possibility to freely rotate on the shaft, there is further provided a small shaped guide roller disposed toward the roller group of the pre-plunging tube made of + metallic band, U-shaped, fixed by the shaft in the middle, with nuts and with the two arms facing outwards.
