Abstract
Description
Streifenbürste mit n zylindrischem Schaft undStrip brush with n cylindrical shaft and
Zentrierkern n zum reinigen der konischen Gasdüse " am Schutzgasschweißbrenner.Centering core n for cleaning the conical gas nozzle "on the inert gas welding torch.
Die Erfindung besteht aus einer " Streifenbürste n (2) (20), mit zylindrischem Schaft (23) oder zylindrischem Handgriff (3), deren Besatz - Borsten - (4) (24) dem Innendurchmesser (D) (B) und der n Konizität " (7) (27) von der Gasdüse (5) (25) angepaßt sind und eiSen Zentrierkern n (10) mit Aufnahmebund (11) welcher dem Durchmesser def Gasdüsenaufnahme ( D I ) entspricht, der mit einer zylindrischen Bohrung (12) in achsialer Richtung versehen ist, in welcher der Handstiel (3) und Schaft (23) zentrisch (radial) geführt wird.The invention consists of a "strip brush n (2) (20), with a cylindrical Shank (23) or cylindrical handle (3), their trimmings - bristles - (4) (24) the inside diameter (D) (B) and the n conicity "(7) (27) of the gas nozzle (5) (25) are adapted and iron centering n (10) with receiving collar (11) which the Diameter def gas nozzle holder (D I) corresponds to that with a cylindrical Bore (12) is provided in the axial direction in which the handle (3) and Shaft (23) is guided centrically (radially).
Die Bürste darf nur im n Halbmesser" 1/2 Df 1/2 bestückt sein, und die Breite vom Besatz - Borsten - nach (s) ausgeführt ist.The brush may only be equipped in the n radius "1/2 Df 1/2, and the width of the trim - bristles - is carried out according to (s).
Das Schutzgassohweißen ist in der Anwendung schon verbreitet, die Vorzüge sind Ja bekannt. Im praktischen Schweißbetrieb hat es sich jedoch gezeigt, daß am Schwei brenner die Gasdüse relativ leicht " verspritzt -"verkokt ".Inert gas welding is already widespread in the application Advantages are known. In practical welding operations, however, it has been shown that that on the welding torch the gas nozzle "splatters" relatively easily - "cokes".
Diese Spritzer können sich bis zu einer Spritzbrücke ansammeln und dadurch einen Kurzschluß im Schweißstromkreis verursachen. Durch diesen überhöhten Widerstand wird der Gleichrichter doch sehr belastet und kann bis zur Schäãigung führen.This splash can collect up to a spray bridge and thereby cause a short circuit in the welding circuit. By this inflated Resistance is the rectifier but very stressed and can up to Schäãigung to lead.
Einen weiteren großen Nachteil haben die Spritzer auch noch, das Schutzgas kann nicht gleichmäßig aus der Düse ausströmen, dadurch können sich sehr leicht in der Schweißnaht Poren bilden und so das Schweißgut beeinträchtigen.Splashes also have another major disadvantage, namely the protective gas cannot flow out of the nozzle evenly, so it can spread very easily form pores in the weld seam and thus impair the weld metal.
Um dieses Ubel zu verringern wird die Gasdüse mit einem Spray benetzt, dieses Sprühmittel erleichtert nur das reinigen der Düse, Rann aber die Verschmutzung nicht verhindern.To reduce this evil, the gas nozzle is wetted with a spray, This spray only makes it easier to clean the nozzle, but it removes dirt not prevent.
Um die Porenbildung zu verringern ist es sehr wichtig, daß man die Gasdüse - reinhaltet - , dies erfordert aber ein Hilfsmittel.In order to reduce pore formation it is very important that the Gas nozzle - keep it clean - but this requires an aid.
Mein erfindungsgemäßer Vorschlag Iv Streifenbürste" hat durch die Anpassung an die Konturen der Gasdüse einen sehr guten Reinigungsgrat, ist sehr handlich und nicht an Anschlüsse -stationär - gebunden.My inventive proposal Iv strip brush "has through the Adaptation to the contours of the gas nozzle a very good cleaning burr, is very Handy and not tied to stationary connections.
Im Großmaschinenbau, bei Stahikonstruktionen und in kleinen Werkstätten ist so eine einfache preiswerte Vorrichtung dhch sehr vorteilhaft.In large machine construction, in steel constructions and in small workshops such a simple, inexpensive device is very advantageous.
Der Durchmesser und die Konizität der Gasdüsen ist unter den einzelnen Typen von Schweißbrennern verschieden, dies erfordert eine Anpassung in der Grieße zur Düse, die Herstellung ist nicht teuer, somit kann man die Typenvielfalt doch berücksichtigen.The diameter and taper of the gas nozzles is different among each Types of welding torches are different, this requires an adjustment in the grit to the nozzle, the production is not expensive, so you can still get the variety consider.
Fig. 1a,b zeigt eine Streifenbürste (2) derenßesatz (4) dem Durchmesser (D ) und der konizität (7) von der Gasdüse (5) angepaßt sind. Die Gasaustrittsöffnung (8) ist hier nur 6a.Fig. 1a, b shows a strip brush (2) whose set (4) the diameter (D) and the conicity (7) of the gas nozzle (5) are adapted. The gas outlet opening (8) is only 6a here.
11 m/m , der Innendurchmesser (D # ) Ca. 18 mlm , deshalb muß man die Streifenbürste (2) durch die Gasdüsenaufnahme (D 1) hindurchstecken, und den Zentrierkern (10) über den Handstiel (3) in die Aufnahmebohrung (D 1#) reinschieben, dadurch erhält die Streifenbürste (2) eine radiale Führung".11 m / m, the inside diameter (D #) approx. 18 mlm, so you have to insert the strip brush (2) through the gas nozzle holder (D 1) and the Push the centering core (10) over the handle (3) into the mounting hole (D 1 #), this gives the strip brush (2) a radial guide ".
Unter Fig. 2hen wir den Zentrierkern (10) mit dem Aufnahmebund (11) dessen Länge nach (A 1 ) und der Durchmesser nach ( D 1 ausgeführt sind. Die Durchgangsbohrung (12) hat den Durchmesser wie der Handstiel (3) oder das Schaft (23).Under Fig. 2 we have the centering core (10) with the receiving collar (11) the length of which is carried out according to (A 1) and the diameter according to (D 1. The through hole (12) has the same diameter as the handle (3) or the shaft (23).
Nach Fig. 3a,b ist eine Streifenbürste (20) zu sehen, deren Besatz (24) in der Länge die Hälfte vom Innendurchmesser (F ) hat .According to Fig. 3a, b, a strip brush (20) can be seen, the trimmings (24) is half the length of the inner diameter (F).
Die Gasdüse (25 ) deren Gasaustrittsöffnung (28) hat einen Durchmesser von ca. 15 m/m , hier dann man die Streifenbürste (20) von vorne in die Gasdüse (25) einführen und dann den Zentrierkern (10) durch die Aufnahmebohrung (D 1 auf das Schaft (23) stecken und so die Führung für die Bürste (20) herstellen.The gas nozzle (25) whose gas outlet opening (28) has a diameter of approx. 15 m / m, here then you insert the strip brush (20) from the front into the gas nozzle (25) and then insert the centering core (10) through the mounting hole (D 1 insert the shaft (23) and create the guide for the brush (20).
