Abstract

The arrangement is intended for producing a bore surrounded by a collar in thin metal plate or a thin-walled metal tube, by friction heat developed by applying a rotating pointed drift under pressure to the metal. To provide for sufficient material to form the collar, a strip or disc is secured to the surface of the metal, e.g by welding or adhesive. The thin metal provides insufficient material from which the collar can be formed. The strip or disc may be secured to the surface of the plate or tube by point-welding or by using a welding electrode with annular contact area whose diameter may be approximately equal to that of the bore to be made. .

Werkwijze voor behulp van een vloeiboor aanbrengen van een kraag in een plaat.Method for applying a collar in a plate using a flow drill.

De uitvinding betreft een werkwijze voor met behulp van een snel om zijn as draaibare doorn uitsluitend door wrijvingswarmte en druk maken van een door een kraag omgeven gat in een dunne metalen plaat of de wand van 5 een dunne metalen buis.The invention relates to a method for using a mandrel rapidly rotatable about its axis solely by frictional heat and pressing a hole surrounded by a collar in a thin metal plate or the wall of a thin metal tube.

Bij het uitvoeren van de bekende werkwijze ontstaat bij dunne platen het probleem dat het aanbrengen van een kraag rond het vervaardigde gat niet mogelijk is. De hoeveelheid materiaal welke vrijkomt bij het maken van *0 een gat is daarvoor onvoldoende.When carrying out the known method, the problem arises with thin plates that the fitting of a collar around the manufactured hole is not possible. The amount of material that is released when making * 0 a hole is insufficient for this.

De uitvinding beoogt hiervoor een oplossing te bieden. Dit wordt volgens de uitvinding bereikt doordat men voorafgaande aan het maken van het gat, ter plaatse van het aan te brengen gat een stuk materiaal aanbrengt.The object of the invention is to provide a solution for this. This is achieved according to the invention in that a piece of material is applied at the location of the hole to be made prior to making the hole.

15 Door aanbrengen van extra materiaal wordt het mogelijk om ook in zeer dunne platen gaten met kragen aan te brengen. Het stuk materiaal kan één plaat of meerdere platen zijn. De plaat kan b.v. door lassen of door lijmen worden bevestigd. De las kan door middel van een 20 ringvormige elektrode zijn aangebracht. Daarbij kan de diameter van de elektrode ongeveer die van het te maken gat zijn.15 By applying extra material it is possible to make holes with collars in very thin plates. The piece of material can be one plate or several plates. The plate can e.g. attached by welding or by gluing. The weld can be arranged by means of an annular electrode. The diameter of the electrode can be approximately that of the hole to be made.

De werkwijze wordt toegelicht aan de hand van dé tekeningen.The method is explained on the basis of the drawings.

Fig.T een perspektivische tekening waarin de werkwijze volgens de uitvinding wordt geïllustreerd aan de hand van het aanbrengen van een gat in een koker;Fig. T is a perspective drawing in which the method according to the invention is illustrated by means of making a hole in a tube;

Fig. 3 shows a perspective view of the mounting of the plate; 8101502 to FIGS. 5 to 8 illustrative embodiments of applying the additional material.

Fig.9 een uitvoering waarbij het extra materiaal aan de onderzijde is aangebracht en 5 Fig.10 een uitvoering waarbij aan weerszijden extra materiaal is aangebracht.Fig. 9 an embodiment in which the extra material is arranged at the bottom and Fig. 10 an embodiment in which extra material is applied on both sides.

Door middel van een snel om zijn as draaibare doorn wordt (zie fig.1) uitsluitend door het uitoefenen van warmte in een koker of pijp een gat aangebracht, waarbij 10 het vrijgekomen materiaal een kraag vormt. Bij zeer dun ne kokers of pijpen is het daartoe benodigde materiaal onvoldoende voorhanden. Volgens de uitvinding wordt door lijmen (fig.1), of lassen (fig.3 t/m 8) extra materiaal in de vorm van een plaat (fig.1, 3, 5 en 7,) of in de vorm van een schijf (fig. 6 en 8) aangebracht.. De plaat of schijf kan ook door puntlassen of ringvormig lassen wordt aangebracht.By means of a mandrel which can rotate rapidly about its axis (see fig. 1) a hole is made only by applying heat in a tube or pipe, the material being released forming a collar. With very thin tubes or pipes, the material required for this is insufficiently available. According to the invention, by gluing (fig. 1), or welding (fig. 3 to 8), additional material in the form of a plate (fig. 1, 3, 5 and 7,) or in the form of a disc (fig. 6 and 8) applied. The plate or disc can also be applied by spot welding or annular welding.
