Abstract
Účelom riešenia je odstránenie umělo vytvořených prekážok vzniklých centrováním hubice, zníženie sil potřebných na centrovanie, zníženie výrobných tolerancií, skrátenie prestojov pri zmene sortimentu výroby a šetrenie elektrickej energie. Uvedeného účelu sa dosiahne centrováním centrovacou vložkou paralelnej časti.The purpose of the solution is to eliminate artificial obstacles caused by centering the nozzle, reduce the forces required for centering, reduce production tolerances, shorten downtimes when changing the production range and save electricity. The stated purpose is achieved by centering with a centering insert of the parallel part.
Description
Vynález sa týká zariadenia na centrovanie hubíc.The invention relates to a device for centering nozzles.
Doteraz používané spůsoby centrovania hubíc sú následovně. Hubica je na teleso hlavy uchytená přírubou so skrutkami, ktoré prekonávajú vnútorné tlaky spracovávaného materiálu a je centrovaná centrovacími skrutkami, ktoré musit túto silu překonat, ako aj sily vznikajúce třením v dosadacích plochách. Druhý sposob centrovania hubíc spočívá v tom, že hubica je na teleso hlavy uchytená skrutkami, pričom vůlía otvorov pre tieto skrutky je taká, aby sa hubica dala centrovat centrovacími skrutkami, pričom na skrutky posobia tie isté sily ako v predchádzajúcom případe. Ďalší sposob centrovania hubíc, ktoré sú z dvoch alebo viacerých častí delené z prevádzkových důvodov je kombinácia sposobov už uvedených. Nevýhodou týchto sposobov sú velké sily, ktoré je třeba pri centrovaní hubíc překonat, zároveň posunutím hubice dochádza k umele vytvořeným překážkám, velké sily potřebné na centrovanie hubíc zhoršuje presnosť centrovania, čo má za následok zvýšenie dovolených tolerancií výrobkov a pri zmene sortimentu aj dlhý prestoj spůsobený vyhriatim. hubici z. povrchu vyhrievacím telesom na pracovnú teplotu, čo je nežiadúce.The methods of nozzle centering used hitherto are as follows. The nozzle is attached to the head body by a flange with screws which overcome the internal pressures of the material being processed and is centered by centering screws which have to overcome this force as well as frictional forces in the bearing surfaces. A second method of centering the nozzles is that the nozzle is fastened to the head body by screws, the clearance of the holes for the screws being such that the nozzle can be centered by the centering screws, and the same forces are applied to the screws as in the previous case. Another method of centering the nozzles, which are divided in two or more parts for operational reasons, is a combination of the methods already mentioned. The disadvantage of these methods is the great forces that need to be overcome when centering the nozzles, while moving the nozzle leads to artificially created obstacles, the great forces required to center the nozzles deteriorate the centering accuracy, resulting in increased tolerances for products and long downtimes caused preheated. nozzle from. the surface of the heating element to the working temperature, which is undesirable.
Tieto nedostatky odstraňuje predmet podlá vynálezu, ktorého podstata spočívá v tom, že pozostáva z telesa hlavy, na ktoré je upínacími skrutkami uchytená hubica, ktorú temperuje vyhrievacie teleso hubice, rozděluje ju tepelný mostík a časť před tepelným mostíkom je izolovaná izolačnou vložkou, je opatřená centrovacími skrutkami, ktorými sa prevádza samotné centrovanie centrovacej vlGžky paralelnej časti, opatrenej reflexívno-vyhrievacím telesom, temperujúce centrovaclu vložku paralelnej časti, vloženej do prednej časti hubice a zaistenej přírubou voči posunutiu.These drawbacks are overcome by the object of the invention, which consists of a head body on which a nozzle is fixed by clamping screws, which is heated by the nozzle heater, divided by a thermal bridge and a part in front of the thermal bridge is insulated by an insulating insert. by means of screws, by which the centering of the centering element of the parallel part, provided with a reflective-heating element, tempering the centering insert of the parallel part, inserted into the front part of the nozzle and secured by the flange against the displacement.
Výhody spočívajú v tom, že centrovanie sa prevádza samotnou centrovacou vložkou paralelnej časti, čím sú vylúčené ostatně faktory vznikajúce pri vytláčaní.The advantage lies in the fact that the centering is carried out by the centering insert of the parallel part itself, thus eliminating the extrusion factors.
Na obrázku je znázorněné zariadenie na centrovanie hubíc v pozdlžnom řeze.The figure shows a device for centering the nozzles in a longitudinal section.
Zariadenie pozostáva z telesa hlavy 11, hubice 1, ktorá je opatřená centrovacími skrutkami 10, upínacími skrutkami 9, vyhrievacím telesom hubice 5, izolačnou vložkou 6, tepelným mostíkom 7, pričom do hubce 1 je vložená centrovacia vložka paralelnej časti 2, ktorá je temperovaná reflexívno-vyhrievacím telesom centrovacej vložky paralelnej časti 4 a je uchytená přírubou 3, skrutkami 8 k hubici 1.The device comprises a head body 11, a nozzle 1, which is provided with centering screws 10, clamping screws 9, a nozzle heater 5, an insulating insert 6, a thermal bridge 7, the centering insert of the parallel part 2 which is tempered reflectively - a heating element of the centering insert of the parallel part 4 and is fastened by a flange 3, by screws 8 to the nozzle 1.
Spracovávaný materiál prechádza cez těleso hlavy 11, ktoré ho usměrňuje v pozdlžnom smere a naň je upínacími skrutkami 9 uchytená hubica 1, ktorá je temperovaná vyhrievacím telesom hubice 5, pričom tepelný mostík 7 odděluje prednú časť hubice 1, ktorá nie je vyhrievaná, ale je opatřená izolačnou vložkou β zabraňujúcou sálaniu tepla, do ovzdušia a centrovacie skrutky 10 centrujú centrovaciu vložku paralelnej časti 2, ktorá s hubicou 1 tvaruje spracovávaný materiál na konečný rozměr a je reflexívno-vyhrievacím telesom centrovacej vložky paralelnej časti 4 temperovaná a přírubou 3 za pomoci skrutiek 6 ustavená do pracovnej polohy.The material to be processed passes through the body of the head 11 which directs it in the longitudinal direction and is clamped by the clamping screws 9 to the nozzle 1, which is tempered by the nozzle heater 5, the thermal bridge 7 separating the front part of the nozzle 1. Insulation liner β preventing heat radiation, the air and centering screws 10 center the centering insert of the parallel part 2, which with the nozzle 1 shapes the processed material to the final dimension and is reflective-heating body of the centering insert of the parallel part 4 tempered and flanged 3 by screws to the working position.
Vynález možno využiť v plastikárskom a gumárenskom priemysle pri výrobě profilov, rúr. dutých nádob a fólií.The invention can be used in the plastics and rubber industries for the production of profiles and pipes. hollow containers and foils.
