Description
7714084-6 tillverkningshastighet vid låga framställningskostnader. 7714084-6 manufacturing speed at low manufacturing costs.
Syftet med uppfinningen är vidare att utforma de försva- gade väggområdena så att de under beaktande av de föreliggande tillverkningsvillkoren helt säkert håller fast skruvarna och _säkert styr dessa under iskruvningsförloppet samt att de möj- liggör en enkel löstagning av skruvarna ur hylsorna efter iskruv- ningen i arbetsstycket. Detta syfte uppnås genom att urtag är an- ordnade i det försvagade väggområdet. Utformas därvid det försva- gade väggomrädet vid en lämplig vidareutveckling av uppfinningen med hjälp av åtminstone ett tvärband som delvis omfattar skruv- gängan hålls skruvarna säkert fast i fästbandet med hjälp av detta tvärband och styrs säkert vid iskruvningen. Dessa fördelar erhålls t.o.m. om, till följd av ogynnsamma tillverkningsvillkor vid extruderingen av plasten, avvikelser uppstår i skruvföljden vid utformningen av hylsorna.The object of the invention is furthermore to design the weakened wall areas so that, in view of the present manufacturing conditions, they securely hold the screws and securely guide them during the screw-in process and that they enable easy detachment of the screws from the sleeves after screw-in. the workpiece. This purpose is achieved by arranging recesses in the weakened wall area. If the weakened wall area is designed in a suitable further development of the invention by means of at least one cross strap which partly comprises the screw thread, the screws are securely held in the fastening strap by means of this cross strap and are securely guided during ice screwing. These benefits are obtained up to and including if, due to unfavorable manufacturing conditions during the extrusion of the plastic, deviations occur in the screw sequence during the design of the sleeves.
Uppfinningen beskrives närmare i det följande i anslutning till bifogade ritningar, på vilka I fig. l är en sidovy av en del av ett skruvband, fig. 2 är ett tvärsnitt efter linjen 2-2 i fig. l, och fig. 3 är ett längdsnitt efter linjen 3-3 i fig. l.The invention is described in more detail in the following in connection with the accompanying drawings, in which Fig. 1 is a side view of a part of a screw band, Fig. 2 is a cross-section along the line 2-2 in Fig. 1, and Fig. 3 is a longitudinal section along line 3-3 of Fig. 1.
I fig. 1 visas ett avsnitt av ett skruvband 1 vars parallellt anordnade skruvar 2 uppvisar ett skaft 3, en skruvgänga 4 och en skalle 5. För fasthållning av skruvarna 2 tjänar ett fästband 6 av elastisk plast, vilket vid utföringsexemplet löper vinkelrätt mot skruvens längsgående axel. Fästbandet kan dock vid ett visst skruv- band, vars skruvar är anordnade vridna i förhållande till varandra, även luta svagt mot skruvarnas längsaxlar.Fig. 1 shows a section of a screw band 1 whose parallel arranged screws 2 have a shaft 3, a screw thread 4 and a skull 5. A fastening band 6 of elastic plastic is used for holding the screws 2, which in the exemplary embodiment runs perpendicular to the longitudinal of the screw. shoulder. However, with a certain screw band, the screws of which are arranged rotated relative to each other, the fastening strap can also tilt slightly towards the longitudinal axes of the screws.
Skruvgängorna 4 omfattas över en del av sin omkrets av hylsor 7 i fästbandet 6, varvid resten av omkretsen tillsluts med hjälp av tvärband 8 som i ett stycke är förbundna med hylsorna 7.The screw threads 4 are comprised over a part of their circumference by sleeves 7 in the fastening strap 6, the rest of the circumference being closed by means of cross straps 8 which are in one piece connected to the sleeves 7.
Fästbandet 6 uppvisar även på en sida av skruvbandet 1 ett för- svagat väggområde 9, i vilket hylsan 7 mellan tvärbanden 8 är för- sedd med ett urtag 10.The fastening strap 6 also has on one side of the screw strap 1 a weakened wall area 9, in which the sleeve 7 between the cross straps 8 is provided with a recess 10.
Den på innersidan av hylsan 7 utformade motgängan ll bildar muttergängan för skruvgängan 4. Vidare är hylsorna 7 förbundna med varandra med hjälp av i ett stycke med hylsorna förbundna liv 12, varvid liven l2 är anordnade i skruvbandets l centrumplan. På en sida av skruvbandet l är liven 12 försedda med förstärkningar 13 7714084-6 vilka sträcker sig utmed fästbandets 6 hela längd.The counter-thread 11 formed on the inside of the sleeve 7 forms the nut thread for the screw thread 4. Furthermore, the sleeves 7 are connected to each other by means of one-piece connected to the sleeves 12, the webs 12 being arranged in the center plane of the screw belt 1. On one side of the screw band 1, the webs 12 are provided with reinforcements 13 which extend along the entire length of the fastening band 6.
Det i fig. l och 3 visade skruvbandet 1 uppvisar i sin högra yttersta ände ett avsnitt av fästbandet 6 från vars hylsa 7 skruven 2 redan frigjorts. Därvid har tvärbanden 8 sprängts men har dock förblivit förbundna med resten av hylsan 7 så att det tomma fästbandet 6 kan lämna iskruvningsverktyget genom en lämp- lig öppning.The screw band 1 shown in Figs. 1 and 3 has at its right outermost end a section of the fastening band 6 from whose sleeve 7 the screw 2 has already been released. In this case, the cross straps 8 have been blasted, but have nevertheless remained connected to the rest of the sleeve 7 so that the empty fastening strap 6 can leave the screw-in tool through a suitable opening.
