Abstract

The equipment is for springs used in motor vehicles, the chambers (6) being arranged in a circle and indexed round a common axis in relation to a blasting unit (1) in a fixed position. The springs (2) are accommodated in clamping and turning mechanisms (3) in each of the chambers. The chambers can be vertical, or horizontal so as to form a drum. Each clamping and turning mechanism can have a force- and movement-measuring system.

Description

Die Erfindung betrifft eine Vorrichtung zum Kugelstrahlen von Schraubendruckfedern für Kraftfahrzeuge, bestehend aus einzelnen, kreisförmig angeordneten und um eine gemeinsame Drehachse taktweise bewegbaren Strahlkammern und mindestens einer zugeordneten, feststehenden Kugelstrahleinrichtung.The invention relates to a device for shot peening of helical compression springs for motor vehicles, consisting of individual, arranged in a circle and cyclically movable about a common axis of rotation Blasting chambers and at least one assigned, fixed shot blasting device.

Anlagen zum Kugelstrahlen von Schraubenfedern, insbeson­ dere von Fahrzeugtragfedern kommen heute weltweit überwie­ gend als Schleuderradanlagen in Standardbauweise zum Ein­ satz.Equipment for shot peening of coil springs, in particular Today, vehicle suspension springs are predominantly used worldwide as a centrifugal wheel system in standard construction sentence.

Der Transport der Federn in und durch den Strahlbereich der Schleuderräder erfolgt mit einer Schleppkette, welche die auf zwei gleichsinnig drehenden Walzen abgelegten Fe­ dern horizontal durch die Strahlanlage schiebt bzw. zieht.The transport of the springs in and through the blasting area the centrifugal wheels are made with a drag chain, which the feet placed on two rollers rotating in the same direction pushes or pulls horizontally through the blasting system.

Die Federn werden von den Walzen durch den vorhandenen Reibschluß in Drehung versetzt, wodurch eine rundum gleichmäßige Bestrahlung der Schraubenfedern erfolgen soll. The springs are removed from the rollers by the existing ones Friction set in rotation, creating an all-round uniform radiation of the coil springs should.  

Nachteilig bei diesem Transportsystem ist, daß bei nicht optimal eingestellten Prozeßparametern, insbesondere der Abstimmung zwischen Vorschubgeschwindigkeit der Schlepp­ kette, Drehzahl der Walzen und Außendurchmesser der Schraubendruckfedern eine mehr oder weniger große Relativ­ bewegung zwischen den Federn und den Walzen auftritt.The disadvantage of this transport system is that it does not optimally set process parameters, especially the Coordination between the feed speed of the towing chain, speed of the rollers and outside diameter of the Helical compression springs a more or less large relative movement occurs between the springs and the rollers.

Diese Relativbewegung führt in Verbindung mit extremen Druck- und Temperaturverhältnissen im Bereich der Linien­ berührung zwischen Feder und Walzen zur Ausbildung so­ genannter Reiblinien, welche in vielen Fällen als stark lebensdauermindernd angesehen werden müssen.This relative movement leads to extreme Pressure and temperature conditions in the area of the lines contact between spring and rollers for training so mentioned friction lines, which in many cases as strong must be viewed as life-reducing.

Zusätzliche Transportprobleme können bei Formfedern auf­ treten, sofern in diesen große Unterschiede in den Win­ dungsdurchmessern oder erhebliche Abweichungen von der Zy­ linderform vorliegen.Additional transport problems can arise with form springs occur, provided that there are large differences in the win diameter or significant deviations from the Zy linden form.

Aus der US 3 675 373 ist eine zentral angeordnete rotie­ rende Strahleinrichtung für feststehende einseitig zu bestrahlende Werkstücke mit einer feststehenden stationären Strahlkammer bekannt. Dabei wird das Strahlmittel in alle Richtungen über den vollen Kreisumfang abgestrahlt. Diese Strahleinrichtung ist aber nicht für Schraubendruckfedern für Kraftfahrzeuge geeignet wie auch die aus der einen älteren Anmeldetag aufweisenden DE 43 44 104 C1 bekannte Anlage nicht.From US 3,675,373 is a centrally arranged rotie beam device for fixed one-sided irradiating workpieces with a stationary stationary Blasting chamber known. The blasting agent is in all Directions emitted across the full circumference. These Beam device is not for helical compression springs not suitable for motor vehicles, nor is the system known from DE 43 44 104 C1, which has an earlier filing date.

Von daher ist es Aufgabe der Erfindung, eine Vorrichtung zum Kugelstrahlen von Schraubendruckfedern für Kraftfahr­ zeuge zu schaffen, die die beschriebenen Nachteile vermei­ det und eine wirtschaftliche Erweiterung der vorhandenen Einsatzmöglichkeiten für das Spannungsstrahlen von Schrau­ bendruckfedern auf einfache Weise bietet.It is therefore an object of the invention to provide a device for shot peening of helical compression springs for motor vehicles to create witnesses that avoid the disadvantages described det and an economic expansion of the existing Possible applications for tension blasting of screws compression springs in a simple way.

Vorteilhafte und zweckmäßige Aus- und Weiterbildungen der erfindungsgemäßen Vorrichtung sind in den Patentansprüchen 2 bis 5 angegeben.Advantageous and expedient training and development of Device according to the invention are in claims 2 to 5 specified.

Die Vorteile der erfindungsgemäßen Vorrichtung sind insbe­ sondere darin zu sehen, daß die sogenannten Reiblinien an den Schraubendruckfedern vermieden werden und gleichzeitig die vorgespannten Schraubendruckfedern auf einfache und wirtschaftliche Weise einer Kugelstrahlbe­ handlung unterzogen werden können, wodurch die Lebensdauer der Schraubendruckfedern erhöht wird.The advantages of the device according to the invention are in particular special to see in that the so-called friction lines the helical compression springs are avoided and  at the same time the pre-tensioned helical compression springs simple and economical way of shot peening can be subjected to action, increasing the lifespan the helical compression springs is increased.
