Description
Verfahren zur Herstellung zwei- oder mehrschenkliger Haarnadeln, insbesondere Bubenkopfkämmchen, aus schrittweise gefördertem, streifenförmigem Werkstoff durch Ausstanzen Es sind bereits Verfahren bekannt, nach denen aus plattenförmigen Werkstoffen Einzelhaarnadeln in bestimmten Formen und Größen durch Ausstanzen hergestellt ;-erden können.Process for the production of two-legged or multi-legged hairpins, in particular Boy's head comb, made of gradually conveyed, strip-shaped material through Punching out There are already known methods according to which from plate-shaped materials Single hairpins in certain shapes and sizes produced by punching; - earthing can.
Bei diesen Verfahren wurden zuerst die V 'erkstoffe in der jeweils erforderlichen Größe zu Platten geschnitten.In these methods, the V were first 'aterials cut into sheets in the required size.
Aus diesen Platten wurden alsdann in mehreren Arbeitsgängen bestimmte Formen von Haarnadeln ausgestanzt.These plates were then used in several steps to determine Punched out shapes of hairpins.
Es ist ferner bekannt, bei Herstellung von Erzeugnissen in Massen einen schrittweise `eförderten Werkstoffstreifen einem Stanzvorgang zu unterwerfen.It is also known in the manufacture of products in bulk to subject a step-by-step conveyed strip of material to a punching process.
Demgegenüber besteht die Erfindung im wesentlichen darin, daß zur Herstellung zwei-oder niehrschenkliger Haarnadeln aus einem fortlaufenden Streifen beim Stanzen an der ersten Arbeitsstelle Werkstoff in der Querrichtung des Streifens entfernt wird, gleichzeitig unter Bearbeitung der einen Längskante durch einen Stanzvorgang, und daß an einer anderen Arbeitsstelle die andere Längskante bearbeitet wird.In contrast, the invention consists essentially in that for Making two-leg or two-leg hairpins from a continuous strip when punching at the first job, material in the transverse direction of the strip is removed, at the same time while processing one longitudinal edge by a punching process, and that the other longitudinal edge is processed at another work site.
In der Zeichnung lassen die Abb. i bis 3 beispielsweise drei Arbeitsstufen erkennen, die an verschiedenen Arbeitsstellen gleichzeitig oder in mehreren Arbeitsgängen vorge; nommen werden können.In the drawing, Figs. I to 3, for example, leave three work stages recognize those at different workplaces at the same time or in several operations featured; can be taken.
Die Ausstanzung erfolgt dergestalt, daß mit einem Werkzeug aus dein fortlaufenden Werkstoffstreifen, quer zu diesem, Werkstoffstücke ausgestanzt werden, wodurch in dem Werkstoffstreifen Ouerstege entstehen, so daß der Werkstoffstreifen eine gitterähnliche Gestalt bekommt (s. Abb. i).The punching is done in such a way that with a tool from your continuous material strips, transversely to this, pieces of material are punched out, whereby Ouerstege arise in the material strip, so that the material strip takes on a grid-like shape (see Fig. i).
Mit diesem Arbeitsgang gleichzeitig werden von der einen Längskante, z. B. b (Abb. i ), des Gitter- oder Nadelwerkstreifens Werkstoffstücke abgestanzt, so daß die betreffende Längskante z. B. aus einzelnen kleinen Bogen sich zusammensetzt, wie in der Abb. i. dargestellt ist.With this operation at the same time, from one longitudinal edge, z. B. b (Fig. I), pieces of material are punched out of the lattice or needlework strip, so that the longitudinal edge in question z. B. is composed of individual small arches, as in Fig. i. is shown.
An einer zweiten Arbeitsstelle wird durch ein Werkzeug gleichzeitig Werkstoff an der zweiten Längskante, nämlich c, entfernt.At a second job, a tool is used at the same time Material on the second longitudinal edge, namely c, removed.
Nachdem von dem Werkstoffstreifen die Ouerstiicke und die entbehrlichen Werkstoffstücke an den zwei Längskanten b und c ausgestanzt sind, werden die stehengebliebenen querliegenden Verbindungsstückeades gitterähnlichen Nadelwerkstreifens (s..Abb. i) durch ein besonderes Werkzeug von ihrem Stanzgrat befreit.After the outer pieces and the dispensable ones from the material strip Pieces of material are punched out on the two longitudinal edges b and c, become the remaining ones transverse connecting pieces on the lattice-like needlework strip (see Fig. i) freed from their punching burr using a special tool.
Dies Befreien vom Stanzgrat kann auch vorher beim Ausstanzen in der Querrichtung des Streifens erfolgen, indem beim Ausstanzen ein Abrunden der Schenkel durch ein entsprechend ausgebildetes Werkzeug vorgenommen wird.This freeing of the punching burr can also be done beforehand when punching out in the The transverse direction of the strip is done by rounding off the legs when punching out is carried out by a suitably designed tool.
Dann findet an einer weiteren Arbeitsstelle das Abtrennen eines zwei- oder mehrschenkligen Werkstückes von dem Werkstreifen statt (s. Abb.3), wobei gleichzeitig eine Formgebung in der Querrichtung, z. B. durch Wölben, vorgenommen werden kann.Then, at another job, the separation of a two- or multi-limbed workpiece from the work strip instead of (s. Fig.3), at the same time shaping in the transverse direction, e.g. B. by arching, can be made.
Es kann auch so verfahren werden, daß ein Abtrennen eines zwei- oder mehrschenkligen Werkstückes von dem Streifen in der Gestalt der Abb. i stattfindet, wobei dann gleichzeitig die eine Längskante, z. B. c, 1111t abgetrennt wird. Hierbei kann auch gleichzeitig eine Formgebung in der Querrichtung vorgenommen werden. Wesentlich ist bei dem Verfahren nur, daß an der ersten Arbeitsstelle zwei Längskanten, z. B. b und c (Abb. i), als Halteleisten für den schrittweise Weiterzufördernden Streifen stehenbleiben, wobei die eine Längskante, z. B. b, schon eine Formgebung erfahren haben kann.It can also be proceeded so that a separation of a two or multi-limbed workpiece from the strip in the shape of Fig. i takes place, then at the same time the one longitudinal edge, z. B. c, 1111t is separated. Here a shaping in the transverse direction can also be carried out at the same time. Essential is in the process only that at the first job two longitudinal edges, z. B. b and c (Fig. I), as holding strips for the strip to be conveyed on step by step stop, with one longitudinal edge, z. B. b, already experienced a shaping may have.
