Description
Vvnález sa týka hadice z ohybného materiálu, na ktorej prinajmenšom jednom koncovom useku je trvalo umiestnené spojovacie zariadenie, ktoré vykazuje pridržiavaci úsek, ktorv je prispôsobený vonkajšiemu a/alebo vnútornému obrysu hadice a hadicu prinajmenšom po úsekoch v axiálnom smere prekrýva.The invention relates to a hose made of a flexible material on which at least one end piece is permanently positioned a coupling device which has a holding section adapted to the outer and / or inner contour of the hose and overlaps the hose at least in sections in the axial direction.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Takéto hadice z ohybného materiálu, na ktorých je umiestnené spojovacie zariadenie, sii známe napríklad z DE 197 43 825. Tam opísaná hadica má na svojom koncovom useku spojovacie zariadenie, ktoré je určené na axiálne zasunutie do na tento účel prispôsobeného spojovacieho protikusa. Spojovacie zariadenie a spojovací protikus spolu tvoria hadicovú spojku. Takéto hadice sa používajú pri výrobe automobilov. Pri tejto hadici môže napríklad ísť o nasávaciu hadicu pre motory vozidiel. Spojovacie zariadenie tx ori hlboko ťahaný kovový prvok, ktorý obopína hadicu tak na jej vonkajšej strane, ako aj na jej vnútornej strane na spôsob manžety. Tento kovový prvok má prstencov ito prebiehajúce vydutia, ktoré materiál ohybnej hadice deformujú, aby tým vytvorili tvarový styk medzi hadicou a kovovým prvkom. V oblasti čelnej strany hadice tvorí tento kovový prvok naviac prstencovú drážku na vloženie tesniaceho krúžku. Aby sa pri spojovacom zariadení, zasunutom do spojovacieho protikusa. dosiahlo čo najtesnejšie spojenie, kovový kus pri pohľade v priereze prechádza neprerušované z vonkajšej strany na vnútornú stranu hadice. Takáto hadica sa síce osvedčila, čo sa týka tešnosti a pevnosti spojenia medzi spojovacím zariadením a hadicou, ale na druhej strane je jej výroba veľmi nákladná.Such hoses of flexible material on which the coupling device is located are known, for example, from DE 197 43 825. The hose described therein has a coupling device at its end section which is intended to be inserted axially into a coupling piece adapted for this purpose. The coupling device and the connecting counterpart together form a hose coupling. Such hoses are used in the manufacture of automobiles. This hose may, for example, be a suction hose for vehicle engines. The coupling device tx ori is a deep-drawn metal element which embraces the hose both on its outside and on its inside in the manner of a collar. This metal element has annularly extending bulges which deform the material of the flexible hose to form a positive fit between the hose and the metal element. In addition, the metal element forms an annular groove for inserting the sealing ring in the region of the hose front. In order for the coupling device to be inserted into the coupling counterpart. as closely as possible, the metal piece, when viewed in cross-section, passes continuously from the outside to the inside of the hose. Although such a hose has proven itself in terms of the tightness and strength of the connection between the coupling device and the hose, on the other hand, it is very expensive to manufacture.
Úlohou tohto vynálezu preto je výrobu hadice zjednodušiť a napriek tomu uskutočniť dostatočne pevne spojenie medzi hadicou a spojovacím zariadením, ako aj účinne utesnenie.It is therefore an object of the present invention to simplify the manufacture of the hose and still make a sufficiently strong connection between the hose and the coupling device as well as to effectively seal.
. Ί .. Ί.
Podstata vynálezuSUMMARY OF THE INVENTION
Táto úloha je podľa tohto vynálezu vyriešená hadicou v úvode uvedeného druhu, pri ktorej spojovacie zariadenie prinajmenšom po úsekoch pozostáva z termoplastu a je na hadicu nanesené vstrekovaním.This object is achieved according to the invention by a hose of the type mentioned above, in which the connection device consists at least in sections of a thermoplastic and is injected onto the hose.
. Toto riešenie je jednoduché a má výhodu, že vstrekovaním sa dá realizovať účinné utesnenie medzi hadicou a spojovacím zariadením. Súčasne je vstrekovanie vhodné na výrobu hadíc podľa tohto vynálezu vo veľkých počtoch kusov pri zodpovedajúco nízkych nákladoch na výrobu. Okrem toho sa vstrekovaním dá dosiahnuť vysoká pevnosť spoja medzi hadicou a spojovacím zariadením. Vstrekovaním sa tiež dajú bez problémov realizovať zložité geometrické prierezy.. This solution is simple and has the advantage that an effective sealing between the hose and the coupling device can be realized by injection molding. At the same time, injection molding is suitable for the manufacture of the hoses of the present invention in large quantities at a correspondingly low production cost. In addition, a high bond strength between the hose and the coupling device can be achieved by injection molding. Intricate geometric cross-sections can also be realized by injection molding without problems.
Vo vvhodnom variante vynálezu môže byť pridržiavaci úsek usporiadaný na vonkajšej strane hadice. Tým sa da zabrániť zmenšeniu prierezu vnútrajška hadice spojovacím zariadením.In a preferred variant of the invention, the holding section can be arranged on the outside of the hose. In this way, the cross-sectional area of the hose interior can be prevented by the coupling device.
Tiež sa môže ukázať výhodným to, keď spojovacie zariadenie bude celé pozostávať z termoplastu. Tak sa dá celé spojovacie zariadenie vyrobiť lacno z jednotného materiáluIt may also prove advantageous if the coupling device consists entirely of a thermoplastic. Thus, the entire coupling device can be made cheaply from a uniform material
Ako termoplast môže byť vhodný polyamid. Tento materiál je výhodný tak z hľadiska pevnosti, ako aj spracovateľnosti.A polyamide may be suitable as a thermoplastic. This material is advantageous in terms of both strength and processability.
Alternatívne môžu byť ako termoplast vhodne aj polyťtalamid (PPA), polyetylénsultid (PPS) alebo vystužený plast.Alternatively, polythalamide (PPA), polyethyleneultide (PPS) or reinforced plastic may also be suitable as thermoplastic.
Aby sa spojenie medzi hadicou a spojovacím zariadením zlepšilo, medzi pridržiavacim úsekom a hadicou môže byť nanesený pridržiavaci prostriedok. Týmto • 1 ' f spôsobom sa dá dosiahnuť pevné spojenie medzi hadicou a spojovacím zariadením, takže sa zlepšia tak pevnosť, ako aj stabilita.In order to improve the connection between the hose and the coupling device, a retaining means may be applied between the holding section and the hose. This • 1 'f method is achieved by solid connection between the hose and coupling device, so as improve strength and stability.
Tiež sa môže ukázať výhodným to, keď je hadica vyrobená z viacerých vrstiev, pričom vrstva. ktorá susedí s pridržiavacim úsekom, pozostáva z plastu, ktorý' sa dá pevne spojiť s plastom spojovacieho zariadenia. Tým sa dá zlepšiť tesnosť a pevnosť.It may also prove advantageous if the hose is made of a plurality of layers, wherein the layer. which is adjacent to the retaining section, consists of a plastic which can be firmly bonded to the plastic of the coupling device. Thus, tightness and strength can be improved.
Vo výhodnom variante hadice môže spojovacie zariadenie vykazovať druhý pridržiavaci úsek na vnútornej strane hadice. Tým sa umožni, aby sa hadica spojila so spojovacím zariadením tak na vnútornej strane, ako aj na svojej vonkajšej strane. Na jednej strane sa tvm dá zlepšiť tesniaci účinok, na druhej strane sa dá zvýšiť aj pevnosť spojenia medzi hadicou a spojovacím zariadením.In a preferred variant of the hose, the coupling device may have a second holding section on the inside of the hose. This allows the hose to connect to the coupling device both on the inside and on its outside. On the one hand, the sealing effect can be improved, on the other hand, the strength of the connection between the hose and the coupling device can also be increased.
Pritom sa tiež môže ukázať výhodným, keď vzdialenosť medzi oboma pridržiavacimi úsekmi bude menšia než hrúbka steny hadice pred nanesením spojovacieho zariadenia. Týmto spôsobom sa dá uskutočniť spojenie silovým stykom medzi spojovacím zariadením a hadicou. Tým, že vzdialenosť medzi oboma pridržiavacimi úsekmi je menšia než hrúbka steny hadice pred nanesením spojovacieho zariadenia, sa môže uskutočniť zovretie hadice.In this case, it may also prove advantageous if the distance between the two holding sections is less than the wall thickness of the hose before the coupling device is applied. In this way, a force-fit connection can be made between the coupling device and the hose. Since the distance between the two retaining sections is less than the wall thickness of the hose before the coupling device is applied, the hose can be clamped.
Zvlášť jednoduché geometrie sa dajú uskutočniť, keď má prvý a/alebo druhý pridržiavaci úsek tvar valcového plášťa a hadica tvar valcovej rúry.Particularly simple geometries can be realized when the first and / or the second holding section is in the form of a cylindrical jacket and the hose is in the form of a cylindrical tube.
Vo výhodnom variante vynálezu môžu ďalej byť prvý a druhý pridržiavaci úsek navzájom spojené do jedného kusa priečkou, prechádzajúcou cez priebežný otvor v hadici. Tým sa dá výroba hadice podľa tohto vynálezu zjednodušiť. Cez priebežný otvor v hadici sa da plast z vonkajšej strany jednoduchým spôsobom priviesť do vnútrajška hadice. Súčasne sa môže vytvoriť tvarový styk medzi hadicou a pridržiavacimi úsekmi.In a preferred variant of the invention, the first and second retaining sections may further be joined together in one piece by a partition extending through a through hole in the hose. Thus, the production of the hose according to the invention can be simplified. Through the through hole in the hose, the plastic can be easily fed from the outside into the inside of the hose. At the same time, a positive fit can be formed between the hose and the retaining sections.
Výhodné pritom tiež môže byť, keď vonkajší obrys priečky zodpovedá v podstate vnútornému obrysu priebežných otvorov. Aj tým sa dá jednoduchým spôsobom vytvoriť tvarov v stvk medzi hadicou a pridržiavacimi úsekmi.It may also be advantageous here if the outer contour of the crossbar corresponds substantially to the inner contour of the through holes. Even in this way, it is possible in a simple manner to form the shapes between the hose and the retaining sections.
Priebežný otvor sa dá uskutočniť jednoduchým spôsobom, napríklad vŕtaním, ak je tento priebežný otvor v podstate valcový.The through hole can be made in a simple manner, for example by drilling, if the through hole is substantially cylindrical.
Vo výhodnom variante vynálezu môže spojovacie zariadenie vykazovať zaskakovaci prvok, výhodne zaskakovaci palec Tým sa dá uskutočniť účinné spojenie medzi spojovacím zariadením a spojovacím protikusom.In a preferred variant of the invention, the coupling device may comprise a snap-in element, preferably a snap-in thumb. An effective connection between the coupling device and the coupling counterpart can thus be realized.
Vo výhodnom variante vynálezu môže hadica na svojej vonkajšej a/alebo vnútornej strane v oblasti koncového úseku vykazovať prinajmenšom jeden výstupok a/alebo prehĺbenie na spojenie tvarovým stykom so spojovacím zariadením. Takýmto tvarovým stykom sa dá dodatočne zvýšiť pevnosť spojenia medzi hadicou a spojovacím zariadením.In a preferred variant of the invention, the hose may have at least one protrusion and / or recess on its outer and / or inner side in the region of the end section for connection by positive engagement with the coupling device. Such a positive connection can additionally increase the strength of the connection between the hose and the coupling device.
Ďalej sa podľa tohto vynálezu nárokuje spôsob výroby ohybnej hadice so spojovacím zariadením, pričom sa hadica pred nástrekom spojovacieho zariadenia tvarovoFurthermore, according to the present invention, a method for producing a flexible hose with a coupling device is claimed, wherein the hose is shaped before the coupling device is sprayed.
-4stabilizuje. Takouto tvarovou stabilizáciou ohybnej hadice sa dá zlepšiť presnosť pri nanášam spojovacieho zariadenia. Tvarovo stabilizovaná hadica sa dá presne vsadiť do formv na vstrekovanie. Tým sa dá zvýšiť tak pevnosť, ako aj tesnosť spoja medzi hadicou a spojovacím zariadením.-4stabilizuje. Such shape stabilization of the flexible hose can improve accuracy when applying the coupling device. The shape-stabilized hose can be precisely inserted into the injection molds. In this way, both the strength and the tightness of the connection between the hose and the coupling device can be increased.
Ako výhodné sa pritom môže ukázať, keď sa tvárová stabilizácia uskutočni chladením. Silným ochladením ohybny plast hadice stvrdne, má preto menšiu tendenciu uhnuť. keď sa vloží do formyIt may prove advantageous in this case if the face stabilization is carried out by cooling. By strongly cooling the flexible plastic of the hose hardens, therefore it has less tendency to bend. when placed in the mold
V jednej forme uskutočnenia vynálezu sa môže tvarová stabilizácia uskutočniť ovinutím koncového úseku napnutým drôtom. Tým sa dá koncový úsek v oblasti spojovacieho zariadenia tak povediac vystužiť. Navinutím drôtu súčasne vznikne tvarový styk medzi hadicou a spojovacím zariadením po nanesení spojovacieho zariadenia.In one embodiment of the invention, the shape stabilization can be accomplished by wrapping the end section with a stretched wire. In this way, the end section in the region of the coupling device can thus be reinforced. At the same time, winding the wire creates a positive connection between the hose and the coupling device after the coupling device has been applied.
V ďalšom vynález bližšie osvetlime pomocou dvoch príkladov uskutočnenia.In the following the invention will be explained in more detail by means of two exemplary embodiments.

Príklad uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Hadica 1 je nasávacia hadica, aká sa používa pre motory motorových vozidiel. Je vyrobená z viacerých vrstiev. Takéto hadice sú v doterajšom stave techniky všeobecne známe. Jednotlivé vrstvy hadice pozostávajú prevažne z elastomérových materiálov, čo poskytuje hadici ohybnosť. Naviac môžu byť do konštrukcie vrstiev hadice 1 integrované textilné vvstužóvacíe vrstvy. To je však z doterajšieho stavu techniky známe, a preto sa to nemusí bližšie objasňovať. Hadica 1 má vnútornú stranu 3, vonkajšiu stranu 4, vždy z elastomérového materiálu, a koncový úsek 5 s čelnou stranou 6. Hadica 1 je vytvorená v podstate v tvare valcovej rúry.Hose 1 is a suction hose used for motor vehicle engines. It is made of several layers. Such hoses are well known in the art. The individual layers of the hose consist mainly of elastomeric materials, which provides the hose with flexibility. In addition, textile reinforcing layers can be integrated into the construction of the layers of the hose 1. However, this is known in the art and therefore need not be explained in detail. The hose 1 has an inner side 3, an outer side 4, each made of an elastomeric material, and an end section 5 with a front side 6. The hose 1 is formed essentially in the form of a cylindrical tube.
Spojovacie zariadenie 2 je usporiadané v oblasti koncového úseku 5 hadice 1 a má pridržiax aci úsek 7. ktorý je vytvorený v tvare valcového plášťa a je usporiadaný na vonkajšej strane 4 hadice 1 a túto prekrýva v axiálnom smere. Vnútorný priemer pridržiax acieho úseku 7 pritom zodpovedá v podstate vonkajšiemu priemeru vonkajšej strany 4. Vnútorný obrys pridržiavacieho úseku je takto prispôsobený vonkajšiemu obrysu hadice.The coupling device 2 is arranged in the region of the end section 5 of the hose 1 and has a retaining section 7 which is formed in the form of a cylindrical sheath and is arranged on the outside 4 of the hose 1 and overlaps it in the axial direction. The inner diameter of the holding section 7 corresponds essentially to the outer diameter of the outer side 4. The inner contour of the holding section is thus adapted to the outer contour of the hose.
Ďalej má spojovacie zariadenie prstencovú prírubu 8, ktorá slúži ako doraz neznazorneného protikusa spojky, do ktorej sa spojovacie zariadenie 2 na napojenie hadice dá zastrčiť. V podstate rovnobežne's pridržiavacím úsekom 7 sa rozprestiera spojovacia plocha 2- ktorá prevezme axiálne vedenie spojovacieho zariadenia 2 pri zasúvaní do spojovacieho protikusa.Furthermore, the coupling device has an annular flange 8 which serves as the stop of the coupling counter (not shown), into which the coupling device 2 for connecting the hose can be plugged. The connecting surface 2 extends substantially parallel to the holding section 7 and assumes the axial guidance of the connecting device 2 as it is inserted into the connecting counterpart.
V oblasti čelnej strany 6 hadice f má spojovacie zariadenie 2 dorazovú plochu JO, o ktorú sa prinajmenšom po úsekoch v axiálnom smere opiera čelná strana hadice 1. Naviac ma spojovacie zariadenie 2 obvodovú drážku ]_[. v ktorej je usporiadaný tesniaci krúžok J_2. Tento tesniaci krúžok sa rozprestiera v radiálnom smere mierne nad spojovaciu plochu 9, aby pri spojovacom zariadení 2, zasunutom do spojovacieho protikusa, k nemu tesniaco priliehal.In the region of the end face 6 of the hose f, the coupling device 2 has a stop surface 10 on which the end face of the hose 1 is supported at least in sections in the axial direction. In addition, the coupling device 2 has a circumferential groove 11. in which a sealing ring 12 is arranged. This sealing ring extends in a radial direction slightly above the connecting surface 9 so that the sealing device is adjacent to it when the connecting device 2 is inserted into the connecting counterpart.
Spojovacie zariadenie 2 má okrem toho zaskakovacie zariadenie 13 vo forme zaskakovacielio palca. Pri zasunutom spojovacom prvku zasahuje ďalší zaskakovaci prvok spojovacieho protikusa do tohto zaskakovacieho palca, aby tým zabránil vypadnutiu, hadice zo spojovacieho protikusa. V znázornení na obr. 1 má spojovacie zariadenie 2 takýto zaskakovaci palec tak na hornej strane, ako aj na spodnej strane.The coupling device 2 furthermore has a snap-in device 13 in the form of a snap-in thumb. When the coupling element is inserted, a further snap-in element of the coupling counter engages in this snap-in thumb to prevent the hose from falling out of the coupling counter. In the illustration of FIG. 1, the coupling device 2 has such a snap-in thumb on both the top and bottom sides.
Spojovacie zariadenie 2 je vyrobene z polyamidu. vybodne PA6.6. Medzi pridržiavacím úsekom 7 spojovacieho zariadenia 2 a vonkajšou stranou 4 hadice 1 sa nachádza pridržiavaci prostriedok. Pri tomto pridržiavacom prostriedku ide o Chemosil 256. Tým vznikne zvlášť pevné a tesné spojenie medzi pridržiavacím úsekom 7 a vonkajšou stranou 4 hadice ý.The coupling device 2 is made of polyamide. nabodne PA6.6. Between the holding section 7 of the coupling device 2 and the outside 4 of the hose 1 there is a holding means. This holding means is Chemosil 256. This provides a particularly strong and tight connection between the holding section 7 and the outside 4 of the hose.
- 6 Na výrobu hadice I so spojovacím zariadením 2 podľa tohto vynálezu sa najprv na hadicu 1 nanesie pridržia\aci prostriedok. Hadica s pridržiavacím prostriedkom sa potom vloží do formy, v ktorej sa spojovacie zariadenie 2 nanesie na hadicu 1 vstrekovaním. Po nastreku spojovacieho zariadenia 2 vznikne v dôsledku zmraštenia hadice pevné spojenie v radiálnom smere medzi spojovacím zariadením 2 a hadicou 1 silovým stykom v axiálnom smere medzi hadicou a spojovacím zariadením. Spojovacím prostriedkom sa zlepší tak tesnosť, ako aj pevnosť spojenia medzi spojovacím zariadením 2 a hadicou 1.In order to manufacture the hose 1 with the coupling device 2 according to the invention, the holding agent is first applied to the hose 1. The hose with the retaining means is then inserted into a mold in which the coupling device 2 is applied to the hose 1 by injection molding. After spraying of the coupling device 2, due to the shrinkage of the hose, a rigid connection is formed in the radial direction between the coupling device 2 and the hose 1 by force contact in the axial direction between the hose and the coupling device. The connection means improve both the tightness and the strength of the connection between the coupling device 2 and the hose 1.
V ďalšom bližšie objasnime druhú formu uskutočnenia vynálezu. Pretože druhá forma uskutočnenia obsahuje časti prvej formy uskutočnenia, druhú formu uskutočnenia vysvetlíme len pomocou rozdielov v porovnaní s prvou formou uskutočnenia. Rovnaké diely sú označené rovnakými vzťahovými značkami.Hereinafter, a second embodiment of the invention will be explained. Since the second embodiment comprises portions of the first embodiment, the second embodiment is explained only by differences from the first embodiment. Identical parts are designated with the same reference numerals.
Naviac k prvému pridržiavítciemu úseku 7 má druhá forma uskutočnenia druhý pridržiav aci úsek _[4, ktorý sa v tvare valcového plášťa rozprestiera rovnobežne s prvým pridržiavacím úsekom 7 a rovnobežne s vnútornou stranou 3 hadice, pričom vnútorný obrys hadice je prispôsobený vonkajšiemu obrysu pridržiavacieho úseku a pridržiavaci úsek prekrýva hadicu v/ axiálnom smere. Vzdialenosť v radiálnom smere medzi prvým pridržiavacím úsekom 7 a druhým pridržiavacím úsekom 14 je o niečo menši než hrúbka steny hadice 1 v radiálnom smere v oblasti koncového úseku. Tým sa dá docieliť spojenie silovým stykom medzi hadicou a spojov acim zariadením 2.In addition to the first retaining section 7, the second embodiment has a second retaining section 14 extending parallel to the first retaining section 7 and parallel to the inner side 3 of the hose in the form of a cylindrical casing, the inner contour of the hose being adapted to the outer contour of the retaining section. the holding section covers the hose in / axial direction. The distance in the radial direction between the first holding section 7 and the second holding section 14 is slightly smaller than the wall thickness of the hose 1 in the radial direction in the region of the end section. In this way, a force-fit connection between the hose and the coupling 2 can be achieved.
Naviac sú vytvorené výstuže J_5. ktoré sa rozprestierajú v oblasti koncového úseku vnútri druhého pridržiavacieho úseku 14 a majú v podstate polvalcový tvar.In addition, reinforcements 15 are provided. which extend in the region of the end section within the second retaining section 14 and have a substantially semi-cylindrical shape.
Ďalej sú prvý pridržiavaci úsek 7 a druhý pridržiavaci úsek 14 spojené navzájom do jedného kusa priečkou 16. Táto priečka 16 sa rozprestiera cez valcový priebežný otvor 17' v hadici 1. Tento priebežný otvor sa dá vyrobiť vŕtaním. Cez tento priebežný otvor priečky je možné ľahšie priviesť plast na vnútornú stranu hadice. Okrem toho vznikne tvarový styk medzi priečkou a priebežným otvorom, pretože vonkajší obrys priečky zodpovedá v nútornému obrysu priebežného otvoru.Furthermore, the first retaining section 7 and the second retaining section 14 are joined together in one piece by a partition 16. This partition 16 extends through a cylindrical through hole 17 'in the hose 1. This through hole can be made by drilling. Through this through hole of the partition, it is easier to feed plastic to the inside of the hose. In addition, there is a positive fit between the crossbar and the through hole, since the outer contour of the crossbar corresponds to the inner contour of the through hole.
Na výrobu druhej formy uskutočnenia sa môže hadica 1 prinajmenšom v oblasti koncového useku 5 ochladiť chladiacim médiom. Tým dôjde k zmrašteniu hadice v radiálnom smere. Potom sa nasadí' do formy na vstrekovanie a spojovacie zariadenie 2 saTo produce the second embodiment, the hose 1 can be cooled with a cooling medium at least in the region of the end section 5. This causes the hose to shrink in the radial direction. It is then put into the injection mold and the coupling device 2 is
- 7 nastrieka na hadicu. Tým, že vzdialenosť medzi prvými oboma pridržiavacimi úsekmi je menšia než hrúbka steny hadice vo východiskovom stave, po nastriekaní spojovacieho zariadenia sa vytvorí silový styk medzi hadicou a spojkou. Tento silový styk umožní trvanlivé naviazanie spojovacieho zariadenia na hadicu 1. Alternatívne sa môže hadica 1 v koncovej oblasti koncového úseku tvarovo stabilizovať aj navinutým drôtom namiesto ochladenia. Drôt sa pritom navíja na vonkajšiu stranu 4 hadice napnutý, v dôsledku čoho drôt vyvolá na vonkajšej strane 4 hadice zúženia. Po tvarovej stabilizácii sa hadica opäť vloží do formy a spojovacie zariadenie sa môže nastriekať na hadicu. Zúženia, vyvolané navinutým drôtom, vedú k tvarovému styku medzi spojovacím zariadením a hadicou 1, pretože spojovacie zariadenie počas nastrekovania nadobudne vonkajší obrys hadice a tým aj navinutého drôtu. Tvarová stabilizácia pomocou navinutého drôtu je vhodná tak na výrobu prvej, ako aj druhej formy uskutočnenia.- 7 spray on hose. Since the distance between the first two retaining sections is less than the wall thickness of the hose in the initial state, a force contact between the hose and the coupling is established after the coupling device has been sprayed. This force contact allows the coupling device to be permanently attached to the hose 1. Alternatively, the hose 1 in the end region of the end section can also be dimensionally stabilized by the wound wire instead of cooling. The wire is wound on the outside of the hose 4 under tension, whereby the wire causes a constriction on the outside 4 of the hose. After the shape stabilization, the hose is reinserted into the mold and the coupling device can be sprayed onto the hose. The constrictions induced by the wound wire lead to a positive fit between the coupling device and the hose 1, since the coupling device acquires the outer contour of the hose and thus of the wound wire during injection. The shape stabilization by the wound wire is suitable for the production of both the first and second embodiments.
Hadica podľa tohto vynálezu môže byť samozrejme vybavená spojovacím zariadením 2 na oboch svojich koncoch.The hose according to the invention can, of course, be provided with a coupling device 2 at both ends.
Hadica podľa tohto vynálezu s naneseným spojovacím zariadením je vhodná pre veľkosériovú výrobu. Tým umožňuje nízke náklady pri výrobe a súčasne vyhovuje požiadavkám na tesnosť a stabilitu. Vstrekovanie okrem toho umožňuje aj zložité tvary podrezania.The hose according to the invention with the applied coupling device is suitable for mass production. This allows low production costs while meeting the tightness and stability requirements. In addition, injection molding allows complex undercut shapes.
