Definitions
- the invention relates to a device for processing tubular components, in particular for producing belt tensioner tubes.
- Tubular components are required in large numbers, particularly in the vehicle industry.
- belt tensioner systems for example, specially shaped belt tensioner tubes are used, in which a propellant is arranged.
- the propellant which is crimped into a shaped tulip in the belt tensioner tube, blows balls in the belt tensioner tube onto a turbine wheel and thereby winds up a seat belt in order to pull a passenger to the backrest in the event of an accident and thereby maximize the available 'braking distance' shape.
- the explosion pressures generated by the propellant are increasing. As a result, an ever greater strength of the pipe is required.
- belt tensioner tubes are either manufactured in many individual stations with manual interlinking or they are manufactured in large-area subsystems with relatively high cycle times. Since massive clamping is always required to hold the tubular components in almost every processing station, high clamping forces are also required, which in individual systems with several processing stations would lead to press rams with a large movement mass and a punch width that is no longer realizable. The high masses to be moved alone would prevent a fast machining process. If, on the other hand, the clamping forces are generated individually in individual stations, this leads to considerable system sizes, which then have to be divided into subsystems.
- a generic device for machining tubular workpieces is known. This has a base body with several processing stations arranged next to one another.
- the base body consists of a lower part serving as a support for the workpieces and an upper part designed as a press ram, between which the workpieces are clamped during processing.
- relatively large masses have to be moved for the simultaneous clamping of several workpieces.
- the object of the invention is to create a device for processing tubular components which is compact and enables a large number of different processing steps with short cycle times.
- the clamping device designed to clamp the workpieces during machining contains a plurality of clamping units arranged at the machining stations of the base body with movable clamping elements which are arranged displaceably on the base body and which can be displaced by means of a clamping bar movably arranged on the base body in its longitudinal direction via resilient clamping levers.
- the central drive of the movable clamping elements via the clamping bar, which can be displaced in the longitudinal direction of the base body enables a large number of consecutive processing and testing stations to be accommodated in a very small space. Repetitive work movements in the various stations can be combined mechanically via a common drive and implemented with an extremely small station spacing.
- the drive of the clamping device can be offset with respect to the machining units while making optimal use of space.
- the workpiece clamping forces of the individual clamping units can be adjusted by suitable selection of the Clamping springs or by simply adjusting their preload paths can be adapted and changed to the respective processing steps. In this way, any workpiece clamping forces from 1 to 30 t can be generated.
- the clamping units can have fixed clamping elements assigned to the movable clamping elements. This allows the workpieces to be clamped between a fixed and a movable clamping element.
- the resilient clamping levers can advantageously be mounted on the base body so as to be rotatable about axes. You can rest with their upper lever arms on the movable clamping elements and engage with their lower lever arms in receptacles on the clamping bar.
- the receptacles can be arranged adjustably on the clamping bar or have exchangeable inserts for receiving the lower lever arms of the clamping lever.
- the resilient clamping levers can be made in one piece from spring steel or another resilient material.
- the resilient clamping levers can also consist of several parts, the upper lever arm e.g. can be made of steel and the lower lever arm of spring steel.
- the clamping bar can be slidably guided on guide rails on a front side of the base part and can be moved by a drive motor via an eccentric drive.
- differently designed processing units are expediently arranged with a ram or slide for driving tools, which is arranged displaceably on the base body.
- the ram or slide can be driven by motor-driven shafts via an eccentric drive with drive eccentric or a cam drive with a cam disc.
- the shafts are expediently rotatable in bearing bores of the base body via pivot bearings stored and driven by drive motors.
- the shafts can be driven separately or by a common drive motor via meshing gears and a gear.
- Figure 1 shows a base body 1 of a device according to the invention for machining tubular components, in particular for producing belt tensioner tubes.
- a plurality of processing stations 2 arranged next to one another for carrying out successive processing steps on tubular components are provided on the base body 1, which is designed here as a longitudinal beam in box construction.
- processing units 3 for carrying out various processing steps, such as punching, thickening, expanding, calibrating and bending processes, are arranged.
- a clamping device with a plurality of clamping units 4, which are arranged at the processing stations 2 and are explained in greater detail below, for holding the tubular components during processing is also provided on the base body 1.
- FIG. 1 For a simplified representation, in Figure 1 only individual processing units 3 and individual clamping units 4 are shown. Depending on the needs and processing requirements, several processing units 3 and clamping units 4, also of different designs, can be attached to the base body 1.
- a transfer device not shown here, through which the tubular workpieces can be transported from one processing station to the next, is also arranged on the base body 1.
- the transfer device can for example consist of one or more grippers that can be moved on one or more guide rails parallel to the base body 1.
- the base body 1 is designed as a horizontally arranged longitudinal member.
- the base body 1 can, however, also be a vertically arranged longitudinal member with several processing stations 2 arranged one above the other.
- a plurality of rams or slides 7, which are arranged next to one another and displaceable in the vertical direction, for actuating the machining units 3 are arranged on a front side 5 of the box-shaped base body 1 supported on mounting rails 6 and designed as a hollow carrier.
- Punching tools, expanding mandrels or other forming and processing tools, for example, can be moved and driven via the displaceably guided ram or slide 7.
- the drive of the plungers or slides 7 can be effected by motor-driven shafts 8 via an eccentric drive with a drive eccentric 9 designed, for example, as an eccentric drive pin or a cam drive with a cam disk 10.
- the shafts 8 are rotatably mounted in corresponding bearing bores 11 of the base body 1 and can be driven by drive motors 12.
- FIG 2 a cross section through the base body 1 in the area of a vertically displaceable ram or slide 7 is shown.
- the shaft 8 which is provided with an eccentric drive pin 9, is rotatably supported via pivot bearings 13 and 14 in a front wall 15 and a rear wall 16 of the base body 1.
- An expanding mandrel 17 for expanding the downwardly bent end of a tubular component 18 is vertically displaceable by means of the slide or slide 7 which can be displaced by means of the shaft 8.
- a gear wheel 20 is attached to its rear end 19 protruding opposite the rear wall 16 of the base body 1.
- a plurality of juxtaposed clamping units 4, each with a movable clamping element 23 displaceably arranged on the base 1 and a fixed clamping element 24 arranged stationary on the base 1, are attached to the processing stations 2 on an upper side 22 of the base 1.
- the movable clamping elements 23 are designed as displaceable clamping jaws and the fixed clamping elements 24 as stationary clamping jaws.
- the movable clamping elements 23 can be displaced by means of a clamping bar 25 arranged movably in the longitudinal direction of the base body 1 via resilient clamping levers 26 and 27.
- the horizontal clamping bar 25 is guided displaceably on the front 5 of the box-shaped base part 5 via horizontal guide rails 28 and can be moved to and fro by a drive motor 29 via an eccentric drive 30.
- a drive motor 29 via an eccentric drive 30.
- Figure 1 only the right part of the clamping bar 25 is shown.
- On the left side of the base body 1, a further part of the clamping bar 25 can be guided displaceably via horizontal guide rails 28.
- the movable clamping elements 23, which are arranged on the upper side 22 of the base body 1 so as to be displaceable in the longitudinal direction thereof, can be displaced by two differently designed clamping levers 26 and 27.

- the clamping levers 26 and 27 rest with their upper lever arms 33 and 34 on the movable clamping elements 23 and engage with their lower lever arm 35 and 36 in cassette-shaped receptacles 37 on the upper side of the clamping bar 25.
- the clamping lever 26 is produced as a one-piece clamping lever made of spring steel or another resilient material.
- the clamping lever 27 consists on the other hand, of two parts, the upper lever arm 34 being made of steel and the lower lever arm 36 being made of spring steel, for example. Other configurations of the resilient clamping levers 26 and 27 are also possible.

Description
Die Erfindung betrifft eine Vorrichtung zur Bearbeitung von rohrförmigen Bauteilen, insbesondere zur Herstellung von Gurtstrafferrohren.The invention relates to a device for processing tubular components, in particular for producing belt tensioner tubes.
Rohrförmige Bauteile werden insbesondere in der Fahrzeugindustrie in großer Zahl benötigt. So werden z.B. bei Gurtstraffersystemen speziell geformte Gurtstrafferrohre eingesetzt, in denen ein Treibsatz angeordnet ist. Der in einer umgeformten Tulpe im Gurtstrafferrohr eingebördelte Treibsatz bläst im Gurtstrafferrohr befindliche Kugeln auf ein Turbinenrad und wickelt dadurch einen Sicherheitsgurt auf, um einen Passagier im Falle eines Unfalls an die Rücklehne zu ziehen und dadurch den zur Verfügung stehenden ,Bremsweg' so groß wie möglich zu gestalten. Um die Effizienz des Systems zu steigern, werden die durch den Treibsatz erzeugten Explosionsdrücke immer höher. Dadurch wird auch eine immer größere Festigkeit des Rohres erforderlich. Insbesondere in dem um die Rückseite des späteren Sprengsatzes herum geformten und zum Auffangen des Rückstoßes des Sprengsatzes ausgebildeten Bereich der Tulpe, in dem sich die Rohrwandstärke durch Aufweiten des Rohres ausdünnt, sind hohe Festigkeiten gefordert. Um diese Ausdünnung zu kompensieren und um im Tulpenbereich eine größere Rohrwandstärke zu erreichen, wird neuerdings die Rohrwandstärke im ganzen Tulpenbereich verdickt. Diese Verdickung über eine relativ lange Distanz, sowie das anschließende Aufweiten und das danach notwendige Beschneiden, Stirnen, etc., erfordert jedoch viele Bearbeitungsstationen. Vielfach sind sogar mehr als 32 Bearbeitungs- und Prüfstationen zur Herstellung eines Gurtstrafferrohrs erforderlich. Derzeit werden derartige Gurtstrafferrohre entweder in vielen Einzelstationen mit manueller Verkettung hergestellt oder sie werden in großflächigen Teilanlagen mit relativ hohen Taktzeiten gefertigt. Da bei nahezu jeder Bearbeitungsstation auch immer eine massive Klemmung zur Halterung der rohrförmigen Bauteile benötigt wird, sind auch hohe Klemmkräfte gefordert, die bei Einzelanlagen mit mehreren Bearbeitungsstationen zu Pressenstößeln mit einer großen Bewegungsmasse und einer nicht mehr realisierbaren Stempelbreite führen würden. Alleine die zu bewegenden hohen Massen würden einem schnellen Bearbeitungsprozess entgegenstehen. Werden die Klemmkräfte dagegen individuell in einzelnen Stationen erzeugt, führt dies zu erheblichen Anlagegrößen, welche dann in Teilanlagen aufgeteilt werden müssen.Tubular components are required in large numbers, particularly in the vehicle industry. In belt tensioner systems, for example, specially shaped belt tensioner tubes are used, in which a propellant is arranged. The propellant, which is crimped into a shaped tulip in the belt tensioner tube, blows balls in the belt tensioner tube onto a turbine wheel and thereby winds up a seat belt in order to pull a passenger to the backrest in the event of an accident and thereby maximize the available 'braking distance' shape. In order to increase the efficiency of the system, the explosion pressures generated by the propellant are increasing. As a result, an ever greater strength of the pipe is required. Particularly in the area of the tulip formed around the back of the later explosive device and designed to absorb the recoil of the explosive device, in which the pipe wall thickness is thinned by expanding the pipe, high strengths are required. In order to compensate for this thinning and to achieve a greater pipe wall thickness in the tulip area, the pipe wall thickness has recently been thickened in the entire tulip area. This thickening over a relatively long distance, as well as the subsequent widening and the subsequent trimming, foreheading, etc., however, requires many processing stations. In many cases, even more than 32 processing and testing stations are required to manufacture a belt tensioner tube. At present, such belt tensioner tubes are either manufactured in many individual stations with manual interlinking or they are manufactured in large-area subsystems with relatively high cycle times. Since massive clamping is always required to hold the tubular components in almost every processing station, high clamping forces are also required, which in individual systems with several processing stations would lead to press rams with a large movement mass and a punch width that is no longer realizable. The high masses to be moved alone would prevent a fast machining process. If, on the other hand, the clamping forces are generated individually in individual stations, this leads to considerable system sizes, which then have to be divided into subsystems.

Diese Aufgabe wird durch eine Vorrichtung zur Bearbeitung von rohrförmigen Bauteilen. mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This task is achieved by a device for processing tubular components. solved with the features of
Bei der erfindungsgemäßen Vorrichtung enthält die zur klemmenden Halterung der Werkstücke während der Bearbeitung konzipierte Klemmeinrichtung mehrere an den Bearbeitungsstationen des Grundkörpers angeordnete Klemmeinheiten mit am Grundkörper verschiebbar angeordneten beweglichen Klemmelementen, die durch einen am Grundkörper in dessen Längsrichtung beweglich angeordneten Klemmbalken über federnde Klemmhebel verschiebbar sind. Durch den zentralen Antrieb der beweglichen Klemmelemente über den in Längsrichtung des Grundkörpers verschiebbaren Klemmbalken wird ermöglicht, dass eine große Anzahl an aufeinanderfolgenden Bearbeitungs- und Prüfstationen auf engstem Raum untergebracht werden können. Sich wiederholende Arbeitsbewegungen in den verschiedenen Stationen können so über einen gemeinsamen Antrieb mechanisch zusammengefasst und mit äußerst geringem Stationsabstand verwirklicht werden. Es werden dadurch kurze Transferwege mit direkt einsehbarem Teiletransfer, ein übersichtlicher Werkzeugaufbau, kurze Taktzeiten, hohe Produktionsgeschwindigkeiten und eine flexible Fertigung mit integrierter Qualitätskontrolle ermöglicht. Durch die Betätigung der Klemmelemente über Klemmfedern kann der Antrieb der Klemmeinrichtung unter optimaler Platzausnutzung gegenüber den Bearbeitungseinheiten versetzt werden. Außerdem können die Werkstückspannkräfte der einzelnen Klemmeinheiten durch geeignete Auswahl der Klemmfedern oder durch einfache Verstellung ihrer Vorspannwege an die jeweiligen Bearbeitungsschritte angepasst und verändert werden. Auf diese Weise können so beliebige Werkstückspannkräfte von 1 bis 30 t erzeugt werden.In the device according to the invention, the clamping device designed to clamp the workpieces during machining contains a plurality of clamping units arranged at the machining stations of the base body with movable clamping elements which are arranged displaceably on the base body and which can be displaced by means of a clamping bar movably arranged on the base body in its longitudinal direction via resilient clamping levers. The central drive of the movable clamping elements via the clamping bar, which can be displaced in the longitudinal direction of the base body, enables a large number of consecutive processing and testing stations to be accommodated in a very small space. Repetitive work movements in the various stations can be combined mechanically via a common drive and implemented with an extremely small station spacing. This enables short transfer paths with directly visible parts transfer, a clear tool structure, short cycle times, high production speeds and flexible production with integrated quality control. By actuating the clamping elements via clamping springs, the drive of the clamping device can be offset with respect to the machining units while making optimal use of space. In addition, the workpiece clamping forces of the individual clamping units can be adjusted by suitable selection of the Clamping springs or by simply adjusting their preload paths can be adapted and changed to the respective processing steps. In this way, any workpiece clamping forces from 1 to 30 t can be generated.
In einer zweckmäßigen Ausführung können die Klemmeinheiten den beweglichen Klemmelementen zugeordnete feste Klemmelemente aufweisen. Dadurch können die Werkstücke zwischen einem festen und einem beweglichen Klemmelement gespannt werden.In an expedient embodiment, the clamping units can have fixed clamping elements assigned to the movable clamping elements. This allows the workpieces to be clamped between a fixed and a movable clamping element.
Die federnden Klemmhebel können in vorteilhafter Weise um Achsen drehbar an dem Grundkörper gelagert sein. Sie können mit ihren oberen Hebelarmen an den beweglichen Klemmelementen anliegen und mit ihren unteren Hebelarmen in Aufnahmen an dem Klemmbalken eingreifen.The resilient clamping levers can advantageously be mounted on the base body so as to be rotatable about axes. You can rest with their upper lever arms on the movable clamping elements and engage with their lower lever arms in receptacles on the clamping bar.
In einer weiteren vorteilhaften Ausgestaltung können die Aufnahmen verstellbar an dem Klemmbalken angeordnet sein oder austauschbare Einsätze zur Aufnahme der unteren Hebelarme der Klemmhebel aufweisen. Dadurch können die Vorspannwege besonders einfach verändert und somit die Klemmkräfte an die jeweiligen Bearbeitungsanforderungen angepasst werden.In a further advantageous embodiment, the receptacles can be arranged adjustably on the clamping bar or have exchangeable inserts for receiving the lower lever arms of the clamping lever. As a result, the preload paths can be changed particularly easily and the clamping forces can thus be adapted to the respective machining requirements.
Die federnden Klemmhebel können einteilig aus Federstahl oder einem anderen federnden Material hergestellt sein. Die federnden Klemmhebel können aber auch aus mehreren Teilen bestehen, wobei der obere Hebelarm z.B. aus Stahl und der untere Hebelarm aus Federstahl hergestellt sein kann.The resilient clamping levers can be made in one piece from spring steel or another resilient material. The resilient clamping levers can also consist of several parts, the upper lever arm e.g. can be made of steel and the lower lever arm of spring steel.
In einer besonders platzsparenden Bauweise kann der Klemmbalken über Führungsschienen verschiebbar an einer Vorderseite des Grundteils geführt und durch einen Antriebsmotor über einen Exzenterantrieb bewegbar sein.In a particularly space-saving design, the clamping bar can be slidably guided on guide rails on a front side of the base part and can be moved by a drive motor via an eccentric drive.
An den Bearbeitungsstationen des Grundkörpers sind zweckmäßigerweise unterschiedlich gestaltete Bearbeitungseinheiten mit einem am Grundkörper verschiebbar angeordneten Stößel oder Schlitten zum Antrieb von Werkzeugen angeordnet. Der Antrieb der Stößel oder Schlitten kann durch motorisch angetriebene Wellen über einen Exzenterantrieb mit Antriebsexzenter oder einen Kurvenantrieb mit einer Kurvenscheibe erfolgen. Die Wellen sind zweckmäßigerweise über Drehlager in Lagerbohrungen des Grundkörpers drehbar gelagert und über Antriebsmotoren angetrieben. Die Wellen können getrennt oder über miteinander kämmende Zahnräder und ein Getriebe von einem gemeinsamen Antriebsmotor angetrieben sein.At the processing stations of the base body, differently designed processing units are expediently arranged with a ram or slide for driving tools, which is arranged displaceably on the base body. The ram or slide can be driven by motor-driven shafts via an eccentric drive with drive eccentric or a cam drive with a cam disc. The shafts are expediently rotatable in bearing bores of the base body via pivot bearings stored and driven by drive motors. The shafts can be driven separately or by a common drive motor via meshing gears and a gear.
