also hexagonal lower ^! - <- eil e '' of the depression of the press die. This lower rope e "has the same diameter or the same cross-section as the finished hexagonal helical spring. In addition, an ejector star g of the known type is arranged in the bottom of the depression of the press die to eject the finished compressed coil springs upwards.

Lter vertically movable. '' Reßsternpel f which the helical spring into the press latrix recess nineindrLiclr.t, can be round or hexagonal in cross-section.

iv 'if you would now want to bring the round coil spring into the press without any further tools and press it onto a hexagon, then the coil spring, so the Linzelfederbindungen bezw both in the horizontal and in the vertical direction. in Its cross-section is greatly deformed, so that a clean, perfectly usable, square coil spring nut never emerges be able.

Therefore, in order to get a clean, perfectly usable seeksetekige coil spring nut, the round coil spring is on the short screw shaft i of an auxiliary screw is placed, the

pf h and iiutter k is polygonal, expediently octagonal, and then the nut k is tightened to the extent that "" ^ !!?) the individual turns the round coil spring are pressed tightly together. The sturdy short auxiliary screw and the round coil spring form thereby a uniformly solid whole.

. ^v iun, the auxiliary screw holding the compressed round helical spring is inserted into the upper part e of the pressing atrix d and with the help of the pressing pin f further down through the central conical pulp! e 'pass into the lower narrower also hexagonal hawks e' of the press-katrize pushed ¹ of the recess which receives the previously round Schraubelfeder its final actual Sechseckfonn, ^ ei this pressing operation, the outwardly slightly cross-section tapering of the individual i'ederwindungen only on circumference of the Vorwerkstuckes compressed, at the same time according to the invention is prevented by the tightly tightened auxiliary screw that the inner diameter bwz. the thickness of the individual i'ederwindungen is changed so that the individual i'ederwindungen lie perfectly on top of one another even after the pressing process.

In the drawing in Fig. 1, for a better illustration, in the upper part of the preS-Iviatrize the! the round helical spring compressed in it and in the lower part of the press-i-matrix the auxiliary screw with the six-second

Compressed coil spring shown.

After now. the coil spring in. the lower part e ^f 'of the die receives its final hexagonal shape; ??! has, the xiili's screw with the compressed · helical spring is inevitably ejected by the lower press ejector g of the die and the pressing process for the next helical spring to be produced can begin again, »

From. of the auxiliary screw that holds the compressed hexagonal helical spring, the screw nut k is now removed and the screw bolt is pushed out with the aid of a correspondingly strong socket of the finished hexagonal helical spring a ¹ . Then cut into the hexagonal coil spring in a known "Heise the thread and then the feechseck-Schraubenf eder mother in a known '' else hardened, so that now the six-eck - chraubenf e ieriiiUtter is finally ready to use.

A plurality of press dies and Prei'Ä-aatrizen be chraubenfedern suitably for mass production disposed, s ο that in one operation J2R & y§ · iuiia more coil springs can be pressed, which the: '' - the coming to use the press for the production of Secheeck Manufacture of the screws! "Ederraut" tern in connection with the manufacture of the round helical spring by the i'eder- ^ dia machine very much simplified and cheaper and thus extremely economical, especially since the pressing and winding tools only one are subject to very minimal wear, so that the present new manufacturing process for rectangular locking coil spring nuts represents a great step forward and enrichment of the technology, the great advantages of which are not even remotely achieved by any of the previously known manufacturing processes »
