Description

Die Erfindung betrifft die Herstellung von örtlich, viexstärkten Klammern für die Befestigung von Breitfußschienen auf eisernen Querschwellen. Insbesondere handelt es sich um die Herstellung der bekannten C-förmigen Klammern, deren unterer, durch eine Öffnung der Querschwelle geführter Teil die Schwelle von unten her zu umfassen vermag, während der andere Teil so gestaltet ist, daß er den Schienenfuß oder einen zwischen die beiden eingeschalteten Schienenkeil umfaßt. Die Erfindung geht von dem bekannten Verfahren aus, bei dem die Rohlinge durch Abschneiden von Bandwerks,toffThe invention relates to the manufacture of locally reinforced brackets for fastening of wide foot rails on iron cross ties. In particular, it concerns the production of the known C-shaped Brackets, the lower part of which is guided through an opening in the crossbar Able to embrace the threshold from below, while the other part is designed in this way is that he has the rail foot or a rail wedge inserted between the two includes. The invention is based on the known method in which the blanks by cutting off tape work, toff

>5 mit etwa T-förmigem Querschnitt gewonnen und diese durch Biegen, Einschneiden, Stanzen oder ähnliche Arbeitsgänge in die Fertigform gebracht werden. Die Anwendung dieses Verfahrens auf die Herstellung der obengenannten Befestigungsklammern erfolgt erfindungsgemäß in der Weise, daß ein Metallstreifen mit einer mittleren durchlaufenden Längsverstärkung verwendet wird. Die Breite dieses Metallstreifens ist gleich der Breite der quer verstärkten Klammern, während die Breite der Längsverstärkung des Streifens so groß ist wie die Breite der Klammerfüße der quer verstärkten Klammern. Dies hat den Vorteil, daß man aus dem gleichen Bandwerkstofr wahlweise Rohlinge für quer verstärkte Klammern und Rohlinge für Klammern mit Längsversteifung herstellen kann. Zerlegt man nämlich den genannten Bandwerkstoff in Stücke, deren Länge gleich der Länge der längs versteiften Klammern ist, so erhält man Rohlinge für diese Klammerart. Schneidet man aber Bandstücke ab, deren Länge gleich der Höhe einer quer verstärkten Klammer ist, so· kann man diese Rohlinge zur Herstellung von quer verstärkten Klammern benutzen. > 5 obtained with an approximately T-shaped cross-section and this by bending, cutting, punching or similar operations into the finished form to be brought. This process is applied to the manufacture of the above fastening clips according to the invention in such a way that a metal strip with a central continuous Longitudinal reinforcement is used. The width of this metal strip is equal to that Width of the transversely reinforced brackets, while the width of the longitudinal reinforcement of the Strip is as large as the width of the clamp feet of the cross-reinforced brackets. This has the advantage that you get out of the same Bandwerkstofr can optionally produce blanks for transversely reinforced staples and blanks for staples with longitudinal stiffening. This is because the band material mentioned is broken up into pieces, the length of which is equal to the length the longitudinally stiffened clamps, you get blanks for this type of clamp. Cuts but pieces of tape are removed, the length of which is equal to the height of a transversely reinforced clamp is, so · you can use these blanks for production use of cross-reinforced brackets.

In der Zeichnung sind einige Ausführungsbeispiele des Verfahrens gemäß der Erfindung dargestellt.In the drawing are some exemplary embodiments of the method according to the invention.

Die Einzelformen der dargestellten Klammern sind nicht Gegenstand der Erfindung. Diese besteht darin, daß für die HerstellungThe individual forms of the brackets shown are not the subject of the invention. This consists in that for the manufacture

von. Klammern mit Längsversteifung (Fig. 3) derselbe Bandwerkstoff verwendet wird, aus dem auch, die Klammern mit in der Querrichtung verlaufender Versteifung (Fig. 5) erzeugt werden. Der Metallstreifen 16 ist mit einer mittleren durchlaufenden Längsverstärkung 16a versehen, deren Breite b gleich der Breite eines Klammerfußes 17 ist. Um die in Fig. 3 dargestellten Klammern mit in der Längsrichtung verlaufender Versteifungsrippe herzustellen, wird der Metallstreifen 16 (Fig. 1 und 2) in T-förmige Stücke zerlegt, deren Umrißform in Fig. ι mit strichpunktierten Linien dargestellt ist. Die Länge L jedes Stückes ist gleich der Gesamtlänge der Klammern. Der auf diese Weise entstandene Rohling wird durch Biegen, Einschneiden, Stanzen oder ähnliche Arbeitsgänge in die Fertigform (Fig. 3) gebracht. Zwecks Herstellung vonfrom. Brackets with longitudinal stiffening (Fig. 3) the same tape material is used from which the brackets with stiffening extending in the transverse direction (Fig. 5) are produced. The metal strip 16 is provided with a central continuous longitudinal reinforcement 1 6 a , the width b of which is equal to the width of a clamp foot 17. In order to produce the brackets shown in FIG. 3 with a stiffening rib extending in the longitudinal direction, the metal strip 16 (FIGS. 1 and 2) is divided into T-shaped pieces, the outline of which is shown in FIG. 1 with dash-dotted lines. The length L of each piece is equal to the total length of the brackets. The blank produced in this way is brought into the finished form (FIG. 3) by bending, cutting, punching or similar operations. In order to manufacture

ao quer verstärkten Klammern gemäß Fig. 5 wird der Metallstreifen 16 in Stücke zerlegt, deren Länge L gleich der Höhe der gestreckten Klammer und deren Breite B gleich, der Breite der Klammer ist. Die Zerlegung erfolgt also derart, daß die Versteifungsrippe 16° in der Querrichtung der Klammern verläuft. In Fig. 4 ist mit strichpunktierten, Linien die Zerlegung des Bandstreifens veranschaulicht. Der verwendete Bandstreifen kann auch, eine Querschnittsform besitzen, wie sie in Fig. 6 dargestellt ist. Der Bandwerkstoff 16 kann auch mit zwei oder mehreren Rippen i6a versehen sein.Ao transversely reinforced brackets according to FIG. 5, the metal strip 16 is broken into pieces, the length L of which is equal to the height of the stretched bracket and whose width B is equal to the width of the bracket. The dismantling is done in such a way that the stiffening rib extends 16 ° in the transverse direction of the clamps. In Fig. 4, the dismantling of the tape strip is illustrated with dash-dotted lines. The tape strip used can also have a cross-sectional shape as shown in FIG. The band material 16 may be provided a i6 also with two or more ribs.
