Description

Schärfrolle zum Abkratzen von Schleifsteinen, insbesondere von solchen zur Herstellung von Holzschliff. Bei den bekannten Schärfrollen für Schleifsteine, hauptsächlich für solche zur Herstellung von Holzschliff, die dem Zwe;@k dienen, die Poren von Schleifsteinen auszukratzen, wenn sie sich mit Holzschlamm vollgesetzt haben, und deren Flächen dadurch nicht mehr angreifen, ist die Auswechselung der Schärfplatten oder Aufsteckspitzen, die auf gefräste oder gebohrte Ringe geschoben werden, vielfach eine zeitraubende Arbeit, besonders d(as Herausschlagen und Einführen der Schärfspitzen. Bei der neuen Schärfrolle, die nur auf den Rollenkörper aufzuschieben ist, ist (las Auswechseln. sehr einfach. Die Erfindung besteht darin, <iaß die die Schärfspitzen tragenden schraubenförmig verlaufenden Stahlbän-ler samt ihren Abstandringen sowie den entsprechend der Endwindungen der Stahlbänder abgesetzten Endscheiben durch ein Zinnbad zu einem Ganzen vereinigt und dieses auf den Rollenkörper aufgeschoben «-ird. Die neue Schärfrolle besteht aus auf hoher Kante gerolltem Bandstahl a (Abb. r ) als Abstandsring für den ebenfalls auf hoher Karte gerolltem Bandstahl b (Abb. 2), der mit Schärfspitzen versehen ist. Die Endseheiben c (Ab'). 3 und d.) sind' -den Endwindungen der Stahlbänder cz und b entsprechend abgesetzt. Die Stahlbandtraghülse d (Abb. 3 und 7) soll den Rollenkörper vor dein Eindrücken schützen. Abb. 5 zeigt die vollständig zusammengesetzte Schärfhülse, wie sie in ein Zinnbad getaucht wird.Sharpening roller for scraping off whetstones, in particular those for producing wood pulp. With the known sharpening rollers for whetstones, mainly for those for the production of wood pulp, which serve the Zwe; @k to scrape out the pores of whetstones when they have filled with wood sludge and their surfaces are no longer attacked, the replacement of the sharpening plates or attachment points that are pushed onto milled or drilled rings, often a time-consuming work, especially the knocking out and insertion of the sharpening points. The invention consists in the fact that the helically running steel strips carrying the sharpening points, including their spacer rings and the end disks, which are offset according to the end turns of the steel strips, are combined into a whole by a tin bath and this is pushed onto the reel body Edge of rolled steel strip a (Fig. R) as a spacer ing for the steel strip b, which is also rolled on a high map (Fig. 2), which is provided with sharpening points. The end discs c (Ab '). 3 and d.) Are set off according to the end turns of the steel strips cz and b. The steel band support sleeve d (Fig. 3 and 7) is intended to protect the roller body from being pushed in. Fig. 5 shows the fully assembled sharpening sleeve as it is immersed in a tin bath.

Abb. 7 zeigt die vollständig zusammengesetzte Schärfrolle.Fig. 7 shows the fully assembled sharpening roller.

Durch das Eintauchen in ein Zinnbad wird den Stahlspitzen die Glashärte genommen, wodurch sie widerstandsfähig werden. Der Zinnüberzug schützt auch vor Rost. Die Hülse wird nach ihrem Abnützen vom Kern abgezogen und durch eine neue ersetzt.Immersing them in a tin bath gives the steel tips their glass hardness taken, which makes them resilient. The tin plating also protects against Rust. After it has worn out, the sleeve is pulled off the core and replaced with a new one replaced.
