Description
KÖRÜKLÜ BORULAR IÇIN BIR IMALAT YÖNTEMI Bulus, kismen veya tamamen bir körük formuna sahip olan ve tercihen üzerinde klips, braket ve benzeri baglanti elemanlari bulunduran bir termoplastik borunun, tek operasyonda üretimine imkan veren bir yöntem üzerinedir. A MANUFACTURING METHOD FOR BELLOWED PIPES The invention is an invention which is partially or completely in the form of a bellows and preferably a device that has clips, brackets and similar fasteners on it. A method that allows the production of thermoplastic pipe in a single operation is on it.
Bulusun Kisa Açiklamasi Bu bulus ile, otomotiv devrelerinin dar kisimlarina yerlesebilen, kolayca takilip sökülebilen, motordan gelen titresimleri absorbe edebilen körüklü borularin üretimine akiskan/ mermi enjeksiyon teknolojileri kullanilarak olanak saglayan bir yöntem amaçlanmaktadir. Brief Description of the Invention With this invention, it can easily be placed in narrow parts of automotive circuits, Bellows that can be attached and detached, can absorb vibrations from the engine enable the production of pipes by using fluid/bullet injection technologies. A method that provides
Akiskan/mermi enjeksiyon teknolojileri ile körüklü boru üretimine olanak saglayan bir yöntemin, üretim adimlarini azaltarak süreci kisaltacagi, üretimi kolay ve basit bir hale getirecegi, üretim maliyetlerini düsürecegi ön görülmektedir. Allows bellows pipe production with fluid/bullet injection technologies A method that provides It is predicted that it will make it easy and simple and reduce production costs. is seen.
Bulusa ait yöntemin ilk asamasinda, kalip boslugu eriyik malzeme ile doldurulmaktadir. Bu asamada, kalibin körük formunu olusturacak bölgesinde düz bir maça takimi bulunmaktadir. Enjeksiyonu takiben kalip boslugunu dolduran eriyik malzeme dis yüzeyinden sogumaya baslamaktadir. Malzemenin iç yüzeyinde kalan nispeten daha sicak ve akiskan malzeme ise kalip bosluguna enjekte edilen basinçli akiskan ya da mermi ile kalip boslugundan süpürülmektedir. Yöntemin bu ilk asamasi sonucunda körüksüz boru seklindeki ara form elde edilmektedir. Yöntemin ikinci asamasinda kalibin körük formunu olusturacak bölgesinde bulunan düz forma sahip maça takimi ayrilmaktadir. In the first stage of the inventive method, the mold cavity is filled with molten material. is being filled. At this stage, in the region of the mold that will form the bellows form. There is a flat set of spades. Mold cavity following injection The molten material that fills it starts to cool from the outer surface. of the material Relatively hot and fluid material remaining on its inner surface enters the mold cavity. from the mold cavity with injected pressurized fluid or projectile. is being swept. As a result of this first stage of the method, the pipe shaped without bellows intermediate form is obtained. In the second stage of the method, the bellows form of the mold The spade team, which has a flat form in the region that will form, is separated.
Bosalan bu bölüme bu maçalara dik konumda bulunan ve iç çeperleri körük formunda olan ikinci maça takimi yerlestirilmektedir. Bu degisim öncesinde ara form içindeki basinç atmosfer basincina esitlenmektedir. Son olarak kalip bosluguna tekrar basinçli akiskan verilerek henüz sogumamis olan ara form, maça çeperlerine dogru sisirilerek çeperlere yapistirilmakta ve amaçlanan Bulusun ayrintili açiklamasi resimler yardimiyla yapilacaktir. Bosalan is located in this section perpendicular to these cores and their inner walls are bellows. The second spade team in form is placed. Before this change The pressure in the intermediate form is equalized to the atmospheric pressure. Lastly the mold The intermediate form, which has not yet cooled by giving a pressurized fluid to the cavity, It is adhered to the walls by inflating towards the walls of the core and the intended Detailed description of the invention will be made with the help of pictures.
Sekil 1' de Bulus konusu yöntem ile elde edilen bir boru gösterilmektedir. 1', 1 Düz Boru 2 Körüksüz ara form 4', 4 Büyük Çapli Düz Bölüm 23 Kalip Boslugu ' Düz maça Takimi Yöntemin birinci asamasi ile ikinci asamasi arasindaki maça degisimi birinci ve ikinci maça takimlarinin hareket ettirilip yer degistirmesi ile sinirlandirilmamaktadir. Bu degisim, sabit maça takiminin üzerinde bulunan hareketli segmanlarin, yöntemin ikinci asamasinda geri çekilmesi ile elde edilebilecegi gibi, körük yapisi alternatif olarak hareketli segmanlarin yöntemin ikinci asamasinda ileriye hareket etmesiyle de olusturulabilir. Figure 1 shows a pipe obtained by the method of the invention. 1', 1 Straight Pipe 2 Intermediate form without bellows 4', 4 Large Diameter Straight Section 23 Die Spaces ' Straight Spade Team The change of spades between the first stage and the second stage of the method by moving and relocating teams of second spades not angered. This change is located on the fixed core set. obtained by withdrawing the moving segments in the second stage of the method. As it can be, the bellows structure is alternatively It can also be created by moving forward in the second stage of the method.
Akiskan/mermi teknolojileri kullanilarak yapilan bu sisirme yönteminde kullanilan maça degisim islemleri verilen örnekler haricinde de çesitlendirilebilmektedir. Örnegin düz ve figürlü maça takimlarinin her biri ikiser yari yerine üç veya daha fazla parçadan olusmus olabilir. Alternatif olarak, körük formu borunun üzerinde 360°'lik bir sekilde çepeçevre olusturulmak yerine belirli bir açisal alani kapsayacak sekilde kismen olusturulmus da olabilir. Bu durumda maça takimlari kullanmak yerine, sadece figürün olusturulacagi bölgede hareketli tek bir düz maça ile tek bir körüklü maça kullanilabilir. In this inflation method using fluid/bullet technologies, Except for the examples given, the core change operations used can be diversified. For example, each of the straight and figured spades It may be composed of three or more parts instead of two halves. Alternative As a result, the bellows form is 360° all around the pipe. partially to cover a particular angular area rather than being created may have been created. In this case, instead of using spades, a single flat core with a single movable core only in the region where the figure will be created. bellows core can be used.
Körüklü boru üretmek için kullanilan bu yöntem, farkli çaplarda kisimlar içeren borularin her kisminin esasen yeknesak et kalinliklarinda elde edilmesini saglamak için de kullanilabilmektedir. Bilindigi üzere bahsi geçen basinçli akiskan teknolojilerinde elde edilebilecek en ince et kalinligi borunun dis çapi ile orantilidir. Bu sebeple bu yöntemler ile elde edilen degisken dis çaplara sahip borular farkli et kalinliklarinda olmaktadir. Bu yüzden, örnegin Sekil 1'de görülen üzerinde ses sönümleyici özellige sahip genis çapli bir genlesme bölümü (4”) bulunan bir boru (1”), ancak üç bölge halinde üretilip, daha sonra bu parçalar kaynakla birlestirilerek imal edilebilmektedir. Bu da gerektirdigi çok sayida operasyon ve ek isçilik sebebiyle hem üretim maliyetlerini yükseltmekte, hem de kalite risklerini arttirmaktadir. Ancak bulus konusu imalat yöntemi ile bu tip rezonatörlü bir borunun tek seferde elde edilebilmesi mümkün hale gelmektedir. Çapsal degisikliklerin disinda, özellikle otomobillerdeki akiskan hatlarinda boru kesitinin bölgesel olarak dairesel olmaktan uzaklasmasina sikça rastlanmaktadir. Bahsi geçen bilinen konvansiyonel basinçli akiskan teknolojilerinde, akiskan ile bosaltilabilen iç bölge, prosesin dogasi geregi borunun degisen dis kesitini takip edememektedir. Bu sebeple, örnegin dairesel kesitle baslayan boru, orta bölgesinde eliptik hale geldigi halde, akiskan tarafindan bosaltilan iç hacim dairesel kalmaya devam etmektedir. This method, which is used to produce bellows pipes, cuts sections of different diameters. obtained in essentially uniform wall thicknesses of all parts of the pipes containing can also be used to ensure As is known, the The thinnest wall thickness that can be obtained in pressurized fluid technologies is proportional to the tooth diameter. For this reason, the variable index obtained by these methods pipes with diameters are in different wall thicknesses. So, for example It is a large diameter instrument with sound dampening feature, as shown in Figure 1. A pipe (1”) with an expansion section (4”), but produced in three zones, These parts can then be manufactured by welding together. This too Due to the large number of operations and additional labor required, both production increases costs and increases quality risks. However With the manufacturing method, which is the subject of the invention, a pipe with this type of resonator is produced in one go. becomes possible to obtain. Apart from diametrical changes, especially in fluid lines in automobiles It often happens that the pipe section moves away from being locally circular. are found. The mentioned conventional pressure fluid technologies, the inner zone that can be emptied with fluid, due to the nature of the process It cannot follow the changing cross section of the pipe. For this reason, for example Although the pipe, which starts with a circular section, becomes elliptical in its middle region, The internal volume emptied by the fluid remains circular.
Bunun sonucu olarak da et kalinliklari, eliptik kesitin uzun kenarinda riskli sekilde incelirken, kisa kenarinda uygunsuz sekilde kalinlasmaktadir. Bulus konusu imalat yöntemi ile bu tip, kesiti bölgesel olarak degisen borularin da görece yeknesak bir et kalinligi dagilimi ile tek seferde rahatlikla elde edilebilmesi mümkün hale gelmektedir. As a result, wall thicknesses are risky on the long side of the elliptical section. While it tapers off, it thickens inappropriately on its short edge. Meet With the manufacturing method in question, this type of pipes with regionally varying cross-sections can also be used. can be easily obtained in one go with a relatively uniform wall thickness distribution. becomes possible.
Alternatif olarak bulus konusu imalat yöntemi, kesitin farkli oldugu yerde daha düsük veya daha yüksek et kalinligina sahip ürün elde etmek için de rahatlikla kullanilabilir. Alternatively, the inventive manufacturing method may be used where the cross-section is different. also in order to obtain a product with a lower or higher wall thickness. can be used conveniently.
Bulus konusu yöntem, polipropilen (PP), polietilen (PE) ve benzeri poliolefinlerin veya polibütilen tereftalat (PBT), termoplastik elastomer (TPE), polifenil sülfür (PPS) veya naylon gibi mühendislik plastiklerinin sekillendi'rilmesinde kullanilabilir. Ayni zamanda bu yöntem, çok katli veya ardisik olarak farkli malzemelerden imal edilmis borularin sekillendirilmesi için de uygundur. The method of the invention is used in polypropylene (PP), polyethylene (PE) and the like. polyolefins or polybutylene terephthalate (PBT), thermoplastic elastomer (TPE), engineering plastics such as polyphenyl sulfide (PPS) or nylon can be used for shaping. At the same time, this method is multi-layer or forming pipes made of different materials sequentially It is also suitable for
Söz konusu imalat yöntemi, konvansiyonel sistemde ayri bir operasyonla üretilip boru üzerine daha sonra bir kaynak islemi ile sabitlenen klips, kelepçe, braket ve benzeri eklentilerin de, tek operasyonda ürün üzerinde olusturulmasina imkan verir.The said manufacturing method is performed in a separate operation in the conventional system. the clip, which is produced and fixed on the pipe with a welding process, clamps, brackets and similar attachments on the product in a single operation. allows it to be created.
