Abstract
Description
Die Erfindung betrifft ein pulverkraftbetriebenes Setzgerät gemäss dem Oberbegriff des
Patentanspruchs 1.The invention relates to a powder-operated setting tool according to the preamble of
Beim Eintreiben von Befestigungselementen mit einem Setzgerät in Aufnahmewerkstoffe von unterschiedlicher Härte und Festigkeit ist der zu überwindende Widerstand verschieden gross. Es besteht deshalb die Forderung, die Eintreibleistung des Setzgerätes den örtlichen Verhältnissen anzupassen. Aus der EP-0 330 950 ist ein Setzgerät bekannt, bei dem Treibladungen einheitlicher Härte verwendet werden. Die unterschiedlichen Eintreibleistungen werden mittels einer geräteseitigen Leistungsregulierung vorgenommen. Die Kolbenführung dieses bekannten Setzgerätes weist eine Laufbohrung auf, in der ein Treibkolben parallel zur Setzrichtung versetzbar angeordnet ist. In die Laufbohrung mündet eine Kartuschenaufnahme und ein Abströmkanal, dessen Querschnittsfläche mittels eines Regulierstiftes veränderbar ist. Da bei diesem bekannten Setzgerät beim Zünden einer Kartusche sofort nach dem Start des Treibkolbens der Abströmkanal freigegeben wird, fällt bereits ein Teil des Treibgasdruckes ab, bevor er sich vollständig aufgebaut hat.When driving fasteners with a setting tool into mounting materials the resistance to be overcome differs from different hardness and strength large. There is therefore a requirement for the driving power of the setting tool to adapt to the local conditions. A setting tool is known from EP-0 330 950 known in which propellant charges of uniform hardness are used. The different Collecting services are carried out by means of a device-based power regulation performed. The piston guide of this known setting tool has a barrel bore on, in which a driving piston is arranged displaceable parallel to the setting direction. A cartridge receptacle and an outflow channel open into the bore Cross-sectional area can be changed by means of a regulating pin. Because with this known setting tool when igniting a cartridge immediately after the start of the driving piston the discharge channel is released, part of the propellant pressure already drops, before he has built up completely.
Der Erfindung liegt die Aufgabe zugrunde, ein wirtschaftlich herstellbares, pulverkraftbetriebenes Setzgerät zu schaffen, bei dem sofort nach dem Start des Treibkolbens ein Abfall des Treibgasdruckes verhindert wird und eine Freigabe des Abströmkanals erst erfolgt, wenn der Treibkolben eine Versetzung in Setzrichtung erfahren hat.The invention has for its object an economically producible, powder power operated To create setting tool, which immediately after the start of the driving piston A drop in the propellant gas pressure is prevented and the discharge channel is only released occurs when the driving piston has been displaced in the setting direction.
Die Lösung dieser Aufgabe erfolgt durch ein pulverkraftbetriebenes Setzgerät, welches
die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist.This problem is solved by a powder-operated setting tool, which
has the features stated in the characterizing section of
Aufgrund der Ausgestaltung des erfindungsgemässen Setzgerätes wird der Abströmkanal nicht direkt beim Start des Treibkolbens in Setzrichtung freigegeben, sondern erst, wenn der Treibkolben nach einer bestimmten Versetzung in Setzrichtung den Dichtbereich freigibt und die Kartuschenaufnahme mit dem Abströmkanal verbindet.Because of the design of the setting tool according to the invention, the outflow channel not released in the setting direction directly at the start of the driving piston, but only if the driving piston moves the sealing area after a certain displacement in the setting direction releases and connects the cartridge holder with the outflow channel.
Aus herstelltechnischen Gründen ist vorzugsweise der Dichtbereich von der Innenwandung einer zylindrischen Vertiefung in einer in Setzrichtung weisenden Anschlagfläche der Kolbenführung und der Aussenwandung eines Ansatzes einer sich entgegen der Setzrichtung weisenden Gegenfläche des Treibkolbens gebildet, wobei die Kartuschenaufnahme in der zylindrischen Vertiefung und der Abströmkanal in der Anschlagfläche in die Laufbohrung münden.For technical reasons, the sealing area is preferably from the inner wall a cylindrical recess in a stop surface pointing in the setting direction the piston guide and the outer wall of an attachment one against each other the setting direction facing counter surface of the driving piston, the Cartridge holder in the cylindrical recess and the outflow channel in the Open the stop surface in the barrel bore.
Vorzugsweise ist der Ansatz zylindrisch ausgebildet. Dadurch werden verbesserte Dichteigenschaften im Dichtbereich erreicht.The approach is preferably cylindrical. This will improve Sealing properties achieved in the sealing area.
Bei Setzgeräten, bei denen Treibkolben mit zwei grossen Druckstufen Verwendung finden, ist zweckmässigerweise die Anschlagfläche Teil eines zylindrischen Vorsprungs, der in Setzrichtung von einem in Setzrichtung weisenden Boden der Kolbenführung abragt, die Gegenfläche des Treibkolbens Teil einer zylindrischen Ausnehmung, die in Setzrichtung von einem entgegen der Setzrichtung weisenden freien Ende des Treibkolbens beabstandet ist und die Durchmesser des zylindrischen Vorsprungs und der zylindrischen Vertiefung im wesentlich gleich gross ausgebildet.For setting tools in which driving pistons with two large pressure stages are used find, the stop surface is expediently part of a cylindrical projection, the in the setting direction of a bottom of the piston guide pointing in the setting direction protrudes, the counter surface of the driving piston part of a cylindrical recess, which in Setting direction from a free end of the driving piston pointing counter to the setting direction is spaced and the diameter of the cylindrical projection and the cylindrical recess of substantially the same size.
Damit der zylindrische Ansatz des Treibkolbens in der Ausgangsstellung des Treibkolbens vollständig in die zylindrische Vertiefung der Kolbenführung ragt, ist vorteilhafterweise der Abstand zwischen dem Boden und der Anschlagfläche der Kolbenführung grösser als der Abstand zwischen der Gegenfläche und dem freien Ende des Treibkolbens.So that the cylindrical approach of the driving piston in the starting position of the driving piston protrudes completely into the cylindrical recess of the piston guide is advantageous the distance between the bottom and the stop surface of the piston guide greater than the distance between the counter surface and the free end of the Driving piston.
Um die weitere Beschleunigung des Treibkolbens bei einem Setzgerät verändern zu können, ist vorteilhafterweise die Querschnittsfläche des Abströmkanals mittels einer Reguliereinrichtung veränderbar. Bei der Reguliereinrichtung handelt es sich beispielsweise um eine, den Abströmkanal im wesentlichen senkrecht durchsetzende Bohrung, in der ein Regulierstift versetzbar angeordnet ist. To change the further acceleration of the driving piston in a setting tool can, the cross-sectional area of the outflow channel is advantageously by means of a Regulating device changeable. The regulating device is, for example around a bore which penetrates the outflow channel essentially vertically, in which is a displaceable regulating pin.
