Description

zlhiagschauiel in sanastrahlmaschinen gehärtete oder ergütete Strahlteila werden nach erfolgter Warmbehandlung in bekannter Weise auf Drehtisch-Wirbel- strahlern dadurch gereinigt odar entzundert. daß bestimmte Mengen feingekörnten Sartgußschrotes oder Drahtkornes durch rotierend bewegte Bchlagsohaufeln mit großer Geschwindigkeit auf die zu bestrahlenden Werkstücke geschleudert werden. Die Schaufeln solcher Maschinen sind im Betrieb einem außergewShnliehe starken StrahlverchleiS unterworfen, wes- halb sie aus Hartmetall gefertigt sind. Nach aergeaerung worden die eohauiellaufzeiten dadurch er- höht, daß anstelle ihres rechteckigen Querschnittes ein verstärkter keilförmiger Verschnitt tritt. Die Konstruktionsform der Keilverstärkung entspricht in ihrer Neigung etwa dem halben Verschleißwinkel der alten Schaufel, so daß bei gleichbleibender Schlagkraft die volle wirksame Schlagfläche über die ganze Schaufelbreite wesentlich länger als bisher erhalten bleibt. zlhiagschauiel in sana blasting machines hardened or tempered beam parts are made after Heat treatment in a known manner on a turntable vortex lamps cleaned or descaled. that certain Quantities of fine-grained cast iron shot or wire grain rotating Bchagsohaufeln are thrown at high speed onto the workpieces to be irradiated. The blades of such machines are in operation one Subject to exceptionally strong jet wear, which is why half they are made of hard metal. After aerating, the eohauiellaufzeiten were thereby increased increases that instead of their rectangular cross-section, a reinforced wedge-shaped waste occurs. The design of the wedge reinforcement corresponds in its inclination to about half the wear angle of the old blade, so that with the same impact force the full effective striking surface over the entire blade width is maintained for much longer than before.

In der Zeichnung ist die Neuerung schematisch dargestellt.In the drawing, the innovation is shown schematically.

Abb. 1a und 1b zeigen die alte Form der Schlagschaufeln. Abb. 2a und 2b die naue Form ; und zwar sind die Abb. la und 2a je ein Schnitt nach der Linie a-b bzw. c-d der Abb. 1b und 2b, die eine Draufsicht auf die Schaufelbreite wiedergeben.Fig. 1a and 1b show the old shape of the impact vanes. Fig. 2a and 2b the precise form; namely the Fig. la and 2a is a section along the line ab or cd in FIGS. 1b and 2b, which show a top view of the blade width.

Der Schaufelquerschnitt 1 wird durch den Betrieb nach kurzer Zeit soweit durch den Verschleiß weggearbeitet, daß nur noch der Restquerschnitt 2 stehen bleibt.
