Abstract
Description
Die Erfindung betrifft eine Schraubenlinksausdreher. Durch die Verwendung des Schraubenlinksausdrehers ist es möglich festsitzende, durch Schraubendrehereinsätze rundgedrehte Maschinen- und Holzschrauben zu entfernen ohne anbohren des Schraubenkopfes und ohne zur Hilfenahme eines Schraubenausdrehers, ohne umliegendes Material zu beschädigen.The invention relates to a screw extractor. By using the left screw extractor, it is possible machine and wood screws turned by screwdriver bits to be removed without drilling the screw head and without the help a screw extractor without damaging the surrounding material.
Gewerbliche Anwendbarkeit: Herstellung: Werkzeugindustrie.Industrial Applicability: Manufacturing: Tool Industry.
Anwendbar in Möbelindustrie/Luftfahrttechnische Betriebe/Montagefirmen/Bootsbau.Applicable in furniture industry / aeronautical companies / assembly companies / boat building.
Der Einsatz von Schrauben ist in der heutigen Montagetechnik unerläßlich.The use of screws is essential in today's assembly technology.
Da es sich hierbei um lösbare Verbindungen handelt, ist es von besonderer Wichtigkeit die eingesetzten Schrauben jederzeit lösen zu können.Since these are detachable connections, it is special The importance of being able to loosen the screws at any time.
In der Praxis werden jedoch häufig die Schrauben durch die Benutzung falscher Schraubendrehereinsätze und verkannten des Schraubendrehers beschädigt.In practice, however, the screws are often used wrong screwdriver bits and misjudged screwdriver damaged.
Da in der Werkzeugaufnahmeaussparung der Schraube Beschädigungen entstanden sind,ist es nicht mehr möglich die Schraube zu lösen. Eine gewaltsame Lösung der beschädigten Schraube hätte zur Folge, daß umliegendes Material mit beschädigt wird.Since damage in the tool holder recess of the screw have arisen, it is no longer possible to loosen the screw. A violent loosening of the damaged screw would result in that surrounding material is also damaged.
Beschreibung der bisherigen Methoden festsitzenden Schrauben zu lösen
sind:
A: Bei Holzschrauben ist die Entfernung der Schrauben nur bedingt möglich.
Senkkopfholzschrauben kann man versuchen anzubohren, wobei der Schrauben
schaft im verbleibenden Material stecken bleibt. Beim anbohren entstehen
Stahlsplitter die eine Verletzungsgefahr der Augen darstellen.Description of the previous methods of loosening stuck screws:
A: With wood screws, removal of the screws is only possible to a limited extent. Countersunk wood screws can be tried to drill into, the screw shaft getting stuck in the remaining material. When drilling, steel splinters are created which pose a risk of injury to the eyes.
Bei Holzhalbrundschrauben kann man versuchen den Schlitz im Schraubenkopf mittels eines Metallsägeblattes zu vertiefen, auch hierbei wird daß umliegende Material beschädigt durch das Sägeblatt.With wooden semicircular screws you can try the slot in the screw head deepening by means of a hacksaw blade, also here that surrounding material damaged by the saw blade.
Anschließend kann man versuchen die Schlitzschraube zu entfernen.Then you can try to remove the slotted screw.
B: Bei Maschinenschrauben geschieht das Entfernen der beschädigten Schraube
folgendermaßen:
Bei Senkkopfschrauben geschieht dies durch den Werkzeugaufnahmeaussparung
anzubohren und mittels eines Schraubenausdrehers herauszudrehen.B: For machine screws, the damaged screw is removed as follows:
With countersunk screws, this is done by drilling the tool holder recess and unscrewing it using a screw extractor.
Bei dem Versuch die Schraube zu lösen, reißt oftmals der Schraubenkopf ab When trying to loosen the screw, the screw head often breaks off
Durch die Bohrung entsteht zwischen Schraubenkopf und Schraubenschaft eine Sollbruchstelle.A hole is created between the screw head and screw shaft through the hole Predetermined breaking point.
Außerdem entstehen durch das Anbohren Metallsplitter wodurch eine erhöhte Verletzungsgefahr besteht.In addition, drilling into metal splinters results in an increased There is a risk of injury.
Fremdkörper (Metallsplitter) können in Maschinenteile hinein gelangen, wodurch einen Maschinenschaden entstehen kann.Foreign bodies (metal splinters) can get into machine parts, causing machine damage can occur.
Desweiteren verbleibt der Schraubenschaft im Material.Furthermore, the screw shaft remains in the material.
Um diese zu entfernen wird zwangsläufig auch das umliegende Material mitbeschädigt.In order to remove this, the surrounding material is also inevitable also damaged.
Bei Halbrundschrauben geschieht das Entfernen der festsitzender Schrauben durch einsägen des beschädigten Schlitzes am Schraubenkopf durch ein Metall sägeblatt.In the case of half-round screws, the fixed screws are removed by sawing the damaged slot on the screw head through a metal saw blade.
Anschließend versucht man mit einem normalen Schräubendreher die Schraube zu entfernen.Then try the screw with a normal screwdriver remove.
Hierbei entstehen durch das Einsägen des Schraubenkopfes und abrutschen des Schraubendrehers Beschädigungen des um liegenden Materials.This is caused by sawing in the screw head and slipping Screwdriver damage to the surrounding material.
Diese Schraubenlösungsversuche werden in der Praxis gehandhabt bei festsitzenden beschädigten Schraubenköpfe.In practice, these screw loosening attempts are handled by stuck people damaged screw heads.
Im Handel ist derzeit nichts vergleichbares erhältlich.Nothing comparable is currently available in the trade.
Diese Problematik ist seit langem bekannt.This problem has been known for a long time.
Eine optimale Lösung dieses Problems wurde bisher nicht erkannt.An optimal solution to this problem has not yet been recognized.
Die Lösung dieses Problems ergibt sich durch die im Patenthauptanspruch 1 genannte Erfindung. The solution to this problem results from that in main claim 1 mentioned invention.
Die Vorteile der Erfindung liegen darin, daß Schrauben mit rundgedrehte Schraubenköpfe ohne vorbohren und ohne Verwendung eines Schraubenausdrehers entfernt werden können.The advantages of the invention lie in the fact that screws with turned Screw heads without pre-drilling and without using a screw extractor can be removed.
Hierdurch entsteht keine Beschädigung des umliegenden Material.This does not damage the surrounding material.
Durch die im Patenthauptanspruch 1 genannten Schraubenlinksausdreher befindlichen Schneidflächen, entsteht bei langsamer Linksdrehung ein Festhaken im rundgedrehten Schraubenkopfmaterial, wodurch sich die festsitzende rundgedrehte Schraube ohne Beschädigung des umliegenden Material entfernen läßt.By the screw extractor mentioned in the main claim 1 cutting surfaces, arises with a slow left turn Fixed hook in the screw head material, which turns the tightly turned screw without damaging the surrounding Can remove material.
Es entsteht keine Sollbruchstelle zwischen Schraubenkopf und Schraubenschaft. Daher komplette Entfernung der Schraube, ohne das der Schraubenkopf abreißt.There is no predetermined breaking point between the screw head and screw shaft. Therefore complete removal of the screw without the screw head tearing off.
Unfallverhütungsvorteile:
Es entstehen keine absplitternde Metallteile und somit auch keine Verletzungs
gefahr für die Haut und Augen.Benefits of accident prevention:
There are no splintering metal parts and therefore no risk of injury to the skin and eyes.
Um die höchst mögliche Wirkung des Schraubenlinksausdrehers zu erzielen, sollte dieser eingesetzt werden sobald eine Beschädigung der Werkzeugaufnahme aussparung an der Schraube festgestellt wird. In order to achieve the maximum possible effect of the left screw extractor, this should be used as soon as the tool holder is damaged recess on the screw is determined.
