Definitions
- the invention relates to an abutment for supporting hollow profile parts when pressing these profile parts with the corner angles arranged in the hollow chambers of the profile parts according to the features of the preamble of claim 1.
- the corresponding longitudinal and transverse spars are mitred and connected with corner brackets introduced into the hollow chambers of the profiles.
- the connection is often made using a corner jointing machine.
- This essentially consists of a table top on which the hollow profile parts to be connected are also inserted Corner angles are placed, a button for exact positioning of the profiles, a punching head with punching body and a tool (punching knife) for pressing the profile parts with the corner angles as well as with an abutment for supporting the profiles during the punching process, so that the profile does not tilt or damage.
- the abutment contains a longitudinally displaceable abutment block with a receptacle for replaceable abutment inserts which are adjustable in height.
- the abutment inserts have to be adapted to the respective profile structure, whereby the manufacturers of the corner connection machines as standard supply different abutment inserts together with the machine, each of which has different lengths and widths. In many cases, however, these standard abutment inserts are not sufficient. In particular when connecting profiles with several offset corner angle chambers, special abutment inserts must be made that correspond exactly to the respective offset of the profile parts, because no profile tolerances can be taken into account.
- the invention is therefore based on the object of disclosing an abutment of the type mentioned at the outset Despite an offset of the contact surfaces for the abutment inserts, pressing the respective profile with several corner angles is possible using standard abutment inserts.
- the invention is essentially based on the idea that the abutment has at least two receiving devices which are arranged hydraulically adjustable in the longitudinal direction. This makes it possible, using standard abutment inserts, to compensate for the offset existing between the contact surfaces of the hollow profile parts by corresponding hydraulic displacement of the receiving devices holding the abutment inserts.
- the ends of the receiving device facing away from the abutment inserts are preferably formed directly as piston-shaped parts which are arranged displaceably in corresponding recesses (cylinders) of the abutment block.
- the respective cylinder space, which is not occupied by the piston-shaped part, is filled with a hydraulic fluid.
- the cylinder spaces of the holding devices filled with the hydraulic fluid are connected to one another by at least one opening and form a closed system, ie there is no direct connection of the hydraulic fluid to an external pressure source when the abutment is used as intended. This ensures that both piston-shaped parts of the receiving device are always subjected to the same pressure. If, during a forward movement, one abutment insert hits the first contact surface of the hollow profile part, then this abutment insert presses the receiving device into the corresponding cylinder of the abutment block.
- This momentary pressure increase then moves the second receiving device towards the second contact surface of the hollow profile part, so that when the abutment block moves further, the second abutment insert also abuts the second contact surface of the hollow profile part according to the offset of the profile and the same compressive force is exerted on both receiving devices.
- This preferred arrangement is therefore an abutment that adapts itself to the respective offset of the profiles.
- the abutment inserts are adjustable in height for precise adaptation to the profile structure.
- the clamping pieces each have a rail-shaped part which engages in a corresponding groove-shaped recess in the abutment inserts, so that the inserts can be displaced along the rail.
- Two guide pistons are provided on both sides symmetrically to the piston-shaped parts of the receiving devices, which are also arranged displaceably in corresponding recesses in the abutment block.
- Profiles in which only an abutment insert is required can also be supported with the abutment according to the invention. For this purpose it is provided to lock the receiving devices in the middle position with a lock.
- Fig. 1 denotes a hollow profile part and 2 and 3 the corner angles to be pressed with the hollow profile part.
- the corresponding punching tools are provided with the reference numerals 4 and 5.
- an abutment which consists essentially of an abutment block 6 with two receiving devices 7 and 8 and two abutment inserts 9 and 10 which can be clamped into the receiving devices.
- the receiving devices 7, 8 each consist of a piston-shaped part 11, 12 and a clamping piece 13, 14, in which the abutment inserts 9, 10 are clamped.
- the piston-shaped parts 11, 12 are arranged displaceably in the direction of their longitudinal axes 100, 101 in corresponding recesses (cylinders) 15, 16 of the abutment block 6.
- the cylinder spaces 17, 18 filled with the hydraulic fluid are connected to one another via a bore 20, so that the The surfaces 21, 22 of the piston-shaped parts 11, 12 facing the liquid 19 each have the same pressure.
- the cylinder spaces 17, 18 filled with the hydraulic fluid 19 also have openings 23, 24, which are generally closed by appropriate plugs and serve as filling openings for the hydraulic fluid 19.
- the part 25 of the clamping piece 13 facing the abutment insert 9 is designed in the form of a rail.
- the rail-shaped part 25 is located in a groove-shaped recess 26 of the abutment insert 9, so that the insert 9 along the rail-shaped part 25 can be moved.
- screws (not shown) are located in corresponding threaded bores 27, 28, which engage in corresponding grooves 29, 30 of the rail-shaped part 25.
- two guide pistons 31, 32 laterally from the piston-shaped part 11 of the receiving device 7 (the same also applies to the receiving device 8). These are fixedly connected at their front end to the clamping piece 13, while the other end is arranged displaceably in corresponding recesses 33, 34 of the abutment block 6.
- the abutment block After inserting the hollow profile part 1 and adjusting the height of the replacement inserts 9, 10 by moving the rail-shaped parts 25 (FIG. 2), the abutment block is moved in the direction of the profile part 1 with the aid of a feed cylinder (not shown). Initially, the abutment insert 9 should abut the first contact surface of the profile 1. The abutment block 6 then continues until the second abutment insert 10 adapts to the offset of the profile 1 and rests on the second contact surface of the profile frame. The abutment block 6 is then locked and the punching process can be triggered.
- the abutment block 6 is not moved and one of the openings designated 23 and 24 in FIG. 1 is connected to a pressure source.
- the piston-shaped parts 11, 12 are then moved in the direction of the profile part 1 until, after both abutment inserts 9, 10 stop, a corresponding pressure is measured on the contact surfaces of the profile 1.
- the pressure measurement can take place with the aid of a pressure sensor which is arranged, for example, at the other opening 23, 24, which is not connected to the pressure source.
- the abutment according to the invention can also be used for profiles in which only one abutment insert is required.
- the receiving devices 7, 8 are locked in the middle position with a lock.
- the lock being designated 35 and consisting of web-shaped parts 36-38 which can be inserted between the abutment block 6 and the clamping pieces 13, 14. Only the clamping piece 13 still contains an abutment insert in this case.

Abstract
Description
Die Erfindung betrifft eine Widerlage zur Abstützung von Hohlprofilteilen beim Verpressen dieser Profilteile mit den in den Hohlkammern der Profilteile angeordneten Eckwinkeln gemäß den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an abutment for supporting hollow profile parts when pressing these profile parts with the corner angles arranged in the hollow chambers of the profile parts according to the features of the preamble of claim 1.
Zur rationellen Fertigung von aus Aluminium- oder Kunststoffhohlprofilen bestehenden Fenster- und Türrahmen werden die entsprechenden Längs- und Querholme auf Gehrung geschnitten und mit in die Hohlkammern der Profile eingebrachten Eckwinkeln verbunden. Die Verbindung erfolgt dabei häufig mit Hilfe einer Eckverbindungsmaschine. Diese besteht im wesentlichen aus einer Tischplatte, auf die die jeweils zu verbindenden Hohlprofilteile mit eingebrachten Eckwinkeln gelegt werden, einem Taster zur genauen Positionierung der Profile, einem Stanzkopf mit Stanzkörper und einem Werkzeug (Stanzmesser) zum Verpressen der Profilteile mit den Eckwinkeln sowie mit einer Widerlage zur Abstützung der Profile beim Stanzvorgang, so daß kein Kippen oder Beschädigen des Profiles erfolgt. Die Widerlage enthält dabei einen längsverschiebbaren Widerlageblock mit einer Aufnahmevorrichtung für auswechselbar und in ihrer Höhe einstellbar angeordneten Widerlageeinsätzen.For the rational production of window and door frames consisting of aluminum or plastic hollow profiles, the corresponding longitudinal and transverse spars are mitred and connected with corner brackets introduced into the hollow chambers of the profiles. The connection is often made using a corner jointing machine. This essentially consists of a table top on which the hollow profile parts to be connected are also inserted Corner angles are placed, a button for exact positioning of the profiles, a punching head with punching body and a tool (punching knife) for pressing the profile parts with the corner angles as well as with an abutment for supporting the profiles during the punching process, so that the profile does not tilt or damage. The abutment contains a longitudinally displaceable abutment block with a receptacle for replaceable abutment inserts which are adjustable in height.
Wie die Stanzmesser müssen auch die Widerlageeinsätze der jeweiligen Profilstruktur angepaßt werden, wobei die Hersteller der Eckverbindungsmaschinen standardmäßig zusammen mit der Maschine unterschiedliche Widerlageeinsätze mitliefern, die jeweils unterschiedliche Längen und Breiten aufweisen. Diese Standard-Widerlageeinsätze reichen indessen in vielen Fällen nicht aus. Insbesondere beim Verbinden von Profilen mit mehreren versetzten Eckwinkelkammern müssen Spezial-Widerlageeinsätze angefertigt werden, die dem jeweiligen Versatz der Profilteile genau entsprechen, weil keine Profiltoleranzen berücksichtigt werden können.Like the punching knives, the abutment inserts have to be adapted to the respective profile structure, whereby the manufacturers of the corner connection machines as standard supply different abutment inserts together with the machine, each of which has different lengths and widths. In many cases, however, these standard abutment inserts are not sufficient. In particular when connecting profiles with several offset corner angle chambers, special abutment inserts must be made that correspond exactly to the respective offset of the profile parts, because no profile tolerances can be taken into account.
Die Herstellung derartiger an die jeweilige Profilstruktur genau angepaßter Widerlageeinsätze ist nicht nur teuer, da es sich regelmäßig um Sonderanfertigungen handelt, sondern ist auch mit relativ langen Lieferzeiten verbunden.The production of such abutment inserts, which are precisely adapted to the respective profile structure, is not only expensive, since it is regularly custom-made, but is also associated with relatively long delivery times.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Widerlage der eingangs erwähnten Art zu offenbaren, mit der trotz eines Versatzes der Anlageflächen für die Widerlageeinsätze ein Verpressen des jeweiligen Profiles mit mehreren Eckwinkeln unter Verwendung von Standard-Widerlageeinsätzen möglich ist.The invention is therefore based on the object of disclosing an abutment of the type mentioned at the outset Despite an offset of the contact surfaces for the abutment inserts, pressing the respective profile with several corner angles is possible using standard abutment inserts.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weitere besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of the characterizing part of claim 1. Further particularly advantageous embodiments of the invention are disclosed in the subclaims.
Die Erfindung beruht im wesentlichen auf dem Gedanken, daß die Widerlage mindestens Zwei Aufnahmevorrichtungen aufweist, die in Längsrichtung hydraulisch einstellbar angeordnet sind. Dadurch ist es möglich, unter Verwendung von Standard-Widerlageeinsätzen den zwischen den Anlageflächen der Hohlprofilteile bestehenden Versatz durch entsprechendes hydraulisches Verschieben der die Widerlageeinsätze haltenden Aufnahmevorrichtungen auszugleichen.The invention is essentially based on the idea that the abutment has at least two receiving devices which are arranged hydraulically adjustable in the longitudinal direction. This makes it possible, using standard abutment inserts, to compensate for the offset existing between the contact surfaces of the hollow profile parts by corresponding hydraulic displacement of the receiving devices holding the abutment inserts.
Vorzugsweise sind dabei die den Widerlageeinsätzen abgewandten Enden der Aufnahmevorrichtung direkt als kolbenförmige Teile ausgebildet, die in entsprechenden Ausnehmungen (Zylinder) des Widerlageblockes verschiebbar angeordnet sind. Der jeweilige, nicht von dem kolbenförmigen Teil beanspruchte Zylinderraum ist mit einer hydraulischen Flüssigkeit ausgefüllt.The ends of the receiving device facing away from the abutment inserts are preferably formed directly as piston-shaped parts which are arranged displaceably in corresponding recesses (cylinders) of the abutment block. The respective cylinder space, which is not occupied by the piston-shaped part, is filled with a hydraulic fluid.
Bei einer bevorzugten Ausgestaltung der erfindungsgemäßen Widerlage sind die mit der hydraulischen Flüssigkeit gefüllten Zylinderräume der Aufnahmevorrichtungen miteinander durch mindestens eine Öffnung verbunden und bilden ein geschlossenes System, d.h. es besteht keine direkte Verbindung der hydraulischen Flüssigkeit zu einer äußeren Druckquelle bei der bestimmungsgemäßen Verwendung der Widerlage. Dadurch wird erreicht, daß beide kolbenförmige Teile der Aufnahmevorrichtung stets mit gleichem Druck beaufschlagt werden. Denn stößt bei einer Vorwärtsbewegung der eine Widerlageeinsatz gegen die erste Anlagefläche des Hohlprofilteiles, so drückt dieser Widerlageeinsatz die Aufnahmevorrichtung in den entsprechenden Zylinder des Widerlageblockes hinein. Durch diese momentane Druckerhöhung wird dann die zweite Aufnahmevorrichtung zur zweiten Anlagefläche des Hohlprofilteiles hinbewegt, so daß bei entsprechender Weiterbewegung des Widerlageblockes auch der zweite Widerlageeinsatz dem Versatz des Profiles entsprechend gegen die zweite Anlagefläche des Hohlprofilteiles stößt und auf beide Aufnahmevorrichtungen die gleiche Druckkraft ausgeübt wird. Es handelt sich bei dieser bevorzugten Anordnung daher um eine sich dem jeweiligen Versatz der Profile selbstanpassende Widerlage.In a preferred embodiment of the abutment according to the invention, the cylinder spaces of the holding devices filled with the hydraulic fluid are connected to one another by at least one opening and form a closed system, ie there is no direct connection of the hydraulic fluid to an external pressure source when the abutment is used as intended. This ensures that both piston-shaped parts of the receiving device are always subjected to the same pressure. If, during a forward movement, one abutment insert hits the first contact surface of the hollow profile part, then this abutment insert presses the receiving device into the corresponding cylinder of the abutment block. This momentary pressure increase then moves the second receiving device towards the second contact surface of the hollow profile part, so that when the abutment block moves further, the second abutment insert also abuts the second contact surface of the hollow profile part according to the offset of the profile and the same compressive force is exerted on both receiving devices. This preferred arrangement is therefore an abutment that adapts itself to the respective offset of the profiles.
Zur genauen Anpassung an die Profilstruktur sind die Widerlageeinsätze in der Höhe einstellbar angeordnet. Hierzu weisen die Spannstücke jeweils ein schienenförmiges Teil auf, welches in eine entsprechende nutenförmige Ausnehmung der Widerlageeinsätze eingreift, so daß die Einsätze entlang der Schiene verschiebbar sind.The abutment inserts are adjustable in height for precise adaptation to the profile structure. For this purpose, the clamping pieces each have a rail-shaped part which engages in a corresponding groove-shaped recess in the abutment inserts, so that the inserts can be displaced along the rail.
Um eine sichere Führung der Aufnahmevorrichtungen in Richtung des Profiles zu erreichen und ein seitliches Verkanten der Aufnahmevorrichtungen zu vermeiden, sind auf beiden Seiten symmetrisch zu den kolbenförmigen Teilen der Aufnahmevorrichtungen jeweils zwei Führungskolben vorgesehen, die ebenfalls in entsprechenden Ausnehmungen des Widerlageblockes verschiebbar angeordnet sind.In order to achieve a safe guidance of the receiving devices in the direction of the profile and to avoid lateral tilting of the receiving devices, Two guide pistons are provided on both sides symmetrically to the piston-shaped parts of the receiving devices, which are also arranged displaceably in corresponding recesses in the abutment block.
Profile, bei denen nur ein Widerlageeinsatz erforderlich ist, können mit der erfindungsgemäßen Widerlage ebenfalls abgestützt werden. Hierzu ist vorgesehen, die Aufnahmevorrichtungen in Mittelstellung mit einer Sperre zu arretieren.Profiles in which only an abutment insert is required can also be supported with the abutment according to the invention. For this purpose it is provided to lock the receiving devices in the middle position with a lock.

In Fig. 1 sind mit 1 ein Hohlprofilteil und mit 2 und 3 die mit dem Hohlprofilteil zu verpressenden Eckwinkel bezeichnet. Die entsprechenden Stanzwerkzeuge sind mit den Bezugszeichen 4 und 5 versehen.In Fig. 1, 1 denotes a hollow profile part and 2 and 3 the corner angles to be pressed with the hollow profile part. The corresponding punching tools are provided with the
Zur Abstützung des Profilteiles 1 dient eine Widerlage, die im wesentlichen aus einem Widerlageblock 6 mit zwei Aufnahmevorrichtungen 7 und 8 sowie zwei in die Aufnahmevorrichtungen einspannbaren Widerlageeinsätzen 9 und 10 besteht.To support the profile part 1 is an abutment, which consists essentially of an
Die Aufnahmevorrichtungen 7, 8 setzen sich jeweils aus einem kolbenförmigen Teil 11, 12 und einem Spannstück 13, 14, in welches die Widerlageeinsätze 9, 10 eingespannt werden, zusammen. Die kolbenförmigen Teile 11, 12 sind in Richtung ihrer Längsachsen 100, 101 in entsprechenden Ausnehmungen (Zylindern) 15, 16 des Widerlageblockes 6 verschiebbar angeordnet. Dabei befindet sich in den nicht durch die kolbenförmigen Teile 11, 12 eingenommenen Zylinderräumen 17, 18 eine hydraulische Flüssigkeit (z.B. Öl) 19. Außerdem sind die mit der hydraulischen Flüssigkeit gefüllten Zylinderräume 17, 18 miteinander über eine Bohrung 20 verbunden, so daß auf die der Flüssigkeit 19 zugewandten Flächen 21, 22 der kolbenförmigen Teile 11, 12 jeweils der gleiche Druck wirkt.The
Die mit der hydraulischen Flüssigkeit 19 gefüllten Zylinder-räume 17, 18 besitzen ferner Öffnungen 23, 24, welche in der Regel durch entsprechende Stopfen verschlossen sind und als Einfüllöffnungen für die Hydraulikflüssigkeit 19 dienen.The
Wie aus Fig.2 ersichtlich ist, ist das dem Widerlageeinsatz 9 zugewandte Teil 25 des Spannstückes 13 schienenförmig ausgebildet. Das schienenförmige Teil 25 befindet sich in einer nutenförmigen Ausnehmung 26 des Widerlageeinsatzes 9, so daß der Einsatz 9 entlang des schienenförmigen Teiles 25 verschoben werden kann. Zur Befestigung des Widerlageeinsatzes 9 an dem schienenförmigen Teil 25 befinden sich in entsprechenden Gewindebohrungen 27, 28 Schrauben (nicht dargestellt), die in entsprechende Nuten 29, 30 des schienenförmigen Teiles 25 eingreifen.As can be seen from FIG. 2, the
Um eine ausreichende Stabilität der Widerlage zu gewährleisten, hat es sich als zweckmäßig erwiesen, seitlich von dem kolbenförmigen Teil 11 der Aufnahmevorrichtung 7 (entsprechendes gilt auch für die Aufnahmevorrichtung 8) zwei Führungskolben 31, 32 anzuordnen. Diese sind an ihrem vorderen Ende fest mit dem Spannstück 13 verbunden, während das andere Ende in entsprechenden Ausnehmungen 33, 34 des Widerlageblockes 6 verschiebbar angeordnet ist.In order to ensure sufficient stability of the abutment, it has proven to be advantageous to arrange two
Im folgenden wird kurz die Wirkungsweise der erfindungsgemäßen Widerlage anhand von Fig.1 erläutert:
Nach Einlegen des Hohlprofilteiles 1 und der Einstellung der Höhe der Wiederlageeinsätze 9,10 durch Verschieben an den schienenförmigen Teilen 25 (Fig.2) wird der Widerlageblock mit Hilfe eines Vorschubzylinders (nicht dargestellt) in Richtung Profilteil 1 gefahren. Dabei möge zunächst der Widerlageeinsatz 9 gegen die erste Anlagefläche des Profiles 1 stoßen. Der Widerlageblock 6 fährt dann solange weiter, bis der zweite Widerlageeinsatz 10 sich dem Versatz des Profiles 1 anpaßt und an der zweiten Anlagefläche des Profilrahmens anliegt. Der Widerlageblock 6 wird anschließend verriegelt, und der Stanzvorgang kann ausgelöst werden.The mode of operation of the abutment according to the invention is briefly explained below with reference to FIG. 1:
After inserting the hollow profile part 1 and adjusting the height of the
Bei einer vorteilhaften Weiterbildung der Erfindung wird auf die Verschiebung des Widerlageblockes 6 verzichtet und eine der in Fig. 1 mit 23 und 24 bezeichneten Öffnungen mit einer Druckquelle verbunden. Durch Erhöhung des Druckes werden dann die kolbenförmigen Teile 11, 12 so lange in Richtung des Profilteiles 1 verschoben, bis nach Anschlag beider Widerlageeinsätze 9, 10 an den Anlageflächen des Profiles 1 ein entsprechender Druck gemessen wird. Die Druckmessung kann dabei mit Hilfe eines Drucksensors erfolgen, welcher beispielsweise an der jeweils anderen, nicht mit der Druckquelle verbundenen Öffnung 23, 24 angeordnet ist.In an advantageous development of the invention, the
Bei Profilen, bei denen nur ein Widerlageeinsatz erforderlich ist, kann die erfindungsgemäße Widerlage ebenfalls verwendet werden. Hierzu werden die Aufnahmevorrichtungen 7,8 in Mittelstellung mit einer Sperre arretiert. Dieses ist schematisch in Fig. 3 dargestellt, wobei die Sperre mit 35 bezeichnet ist und aus stegförmigen Teilen 36 - 38 besteht, welche zwischen dem Widerlageblock 6 und den Spannstücken 13, 14 einsetzbar sind. Lediglich das Spannstück 13 enthält in diesem Fall noch einen Widerlageeinsatz.The abutment according to the invention can also be used for profiles in which only one abutment insert is required.
