Description

Bekannt sind Handblechscheren, die besondere, durch Anschrauben befestigte Messer haben.Hand tin snips are known, the special knives that are attached by screwing to have.

Vorliegende Erfindung betrifft eine Handblechschere, bei welcher in zur Schnittebene schräge Nuten der Scherenkörper Messer eingesetzt bzw. eingepreßt sind, die durch ihre Neigung ein seitliches Schleifen nicht erfordern. The present invention relates to hand sheet metal shears in which in the cutting plane inclined grooves of the scissors body are inserted or pressed in by their knives Incline does not require side sanding.

ίο Die Nuten zur Aufnahme der Messer sind zum Scherendrehpunkt zu tiefer gefräst, wodurch erreicht wird, daß die Messerschneiden (bei Verwendung von Messern gleichbleibender Breite) nach der Scherenspitze zu iiberragen und dadurch beim zunehmenden Schneiden der Schere eine zunehmende Spannung d.er Messerschneiden gegenseitig erfolgt.ίο The grooves for receiving the knives are Milled too deeper towards the center of rotation of the scissors, which means that the knife edges (when using knives of constant width) to project beyond the tip of the scissors and as a result, as the scissors cut more and more, there is increasing tension between the knife edges.

«ο Schere, Abb. 3 einen Grundriß der einen Scherenhälfte. In schräge Nuten der .Scherenkörper α und b sind die beiden flachen Messer c und d eingesetzt bzw. eingepreßt. Die Nuten sind zum: Scherendrehpunkt e zu (Abb. 1) tiefer gefräst, so daß die Messer nach der Scherenspitze zu seitlich überragen und beim Schneiden eine Spannung erzeugen (Abb. 3).«Ο Scissors, Fig. 3 a plan of one half of the scissors. The two flat knives c and d are inserted or pressed into the inclined grooves of the scissors body α and b. The grooves are milled deeper towards: the scissor pivot point e to (Fig. 1) so that the knives protrude laterally towards the scissor tip and generate tension when cutting (Fig. 3).
