Abstract

The invention relates to a comminution machine having a stationary anvil and rotating hammer strike iron. In such machines, when hammer heads are worn out, the entire hammer strike iron must always be replaced, insofar as a uniform quality is to be achieved in the comminuted material. This is very cost-intensive. The invention thus proposes a novel hammer strike iron having an insert piece which has a cylindrical, eccentric bore or an eccentric oblong hole for receiving a swivel pin of the comminution machine. Said insert piece has cheeks of differing thickness on both ends, such that, by rotating the insert piece in the hammer strike iron by 180°, the distance between the hammer head and the anvil can be varied. If a hammer head has been inadmissibly worn, the insert piece can be removed, turned 180°, and and reinstalled. The gap between the anvil and the hammer head can thus be uniformly regulated.

For the shredding of metal scrap or other mix are the
Fachwelt heute Zerkleinerungsmaschinen, wie z. B. Hammermühlen oder Shred- der, zur Verfügung. Derartige Maschinen sind so aufgebaut, dass Hammerschlageisen (im Folgenden auch als Hammer bezeichnet) mit einem Schwenkbolzen schwenkbar an einem Rotor befestigt sind und beim Rotieren des Rotors radial nach außen durch die bei der Rotation entstehenden Fliehkräfte in Richtung eines feststehenden, mit einem Maschinengestell fest verbundenen Ambosses geschleudert werden. Durch den zwischen dem Amboss und den Hammerschlagleisten festgelegten Spalt wird der Feinheitsgrad des zerkleinerten Materials bestimmt. Hierbei ist zu beachten, dass bei maximaler Rotationsgeschwindigkeit des Rotors der Abstand zwischen Amboss und dem Hammerkopf (d.h. der am weitesten vorragende Teil des Hammers) ein vorher bestimmtes Minimum bzw. Maximum weder unter- noch überschreiten darf. Eine Berührung von Hammerkopf und Amboss ist zu vermeiden, da sie zur Zerstörung der Maschine führen würde. Ebenso würde eine Überschreitung des maximal zulässigen Spalts bzw. Abstands zwi- sehen Hammerkopf und Amboss die Fun ktionsfähigkeit der Maschine wesentlich beeinträchtigen. In einem solchen Falle würde das Zerkleinerungsgut in seiner Größe nicht mehr der gewünschten Korngröße entsprechen. Professionals today shredders, such. As hammer mills or shredders, available. Such machines are constructed so that hammer-blower iron (hereinafter also referred to as hammer) are pivotally mounted on a rotor with a pivot pin and when rotating the rotor radially outwardly by the centrifugal forces generated during rotation in the direction of a fixed, firmly connected to a machine frame Anvils are hurled. The degree of fineness of the crushed material is determined by the gap defined between the anvil and the hammer-blow strips. It should be noted that at maximum rotor rotational speed, the distance between the anvil and the hammerhead (i.e., the most projecting portion of the hammer) must not exceed or undershoot a predetermined minimum or maximum. Contact with the hammer head and anvil should be avoided as it would lead to the destruction of the machine. Likewise, exceeding the maximum allowable gap or distance between the hammer head and the anvil would significantly impair the ability of the machine to function. In such a case, the size of the comminuted material would no longer correspond to the desired particle size.
Für einen einwandfreien Betrieb einer derartigen Zerkleinerungsmaschine ist da- her die Größe des Spalts zwischen Hammerkopf und Amboss von entscheidender Bedeutung. Um die Größe des Spalts zwischen Hammerkopf und Amboss innerhalb vorgegebener Toleranzen zu halten, auch bei Verschleiß am Hammerkopf, muss bisher ein verschlissener Hammer durch einen neuen Flammer ersetzt werden. Dies ist sehr zeitaufwendig, da bisher nur die Beschaffung eines neuen Hammers Abhilfe schaffen konnte. Außerdem ist ein neuer Hammer sehr teuer. Es ist daher ein Bestreben der Fachwelt die Nutzungsdauer (Standzeit) eines Hammers zu verlängern. Therefore, the size of the gap between the hammer head and the anvil is of decisive importance for a perfect operation of such a comminution machine. In order to keep the size of the gap between the hammer head and anvil within predetermined tolerances, even with wear on the hammer head, previously a worn hammer must be replaced by a new flame. This is very time consuming, since so far only the procurement of a new hammer could remedy. In addition, a new hammer is very expensive. It is therefore a desire of the art to extend the useful life (life) of a hammer.
Aufgabe der Erfindung ist es, verbesserte Hammerschlageisen für eine Zerkleine- rungsmaschine der eingangs genannten Art anzugeben, die eine längere Nutzungsdauer aufweisen, um Betriebskosten zu senken, ohne die Qualität des zerkleinerten Produkts negativ zu beeinflussen. Diese Aufgabe wird durch die Erfindung gelöst, die in den unabhängigen Ansprüchen definiert ist; Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen definiert. Zur Lösung dieser Aufgabe offenbart die Erfindung Hammerschlageisen für eine Zerkleinerungsmaschine mit feststehendem Amboss, wobei das Hammerschlageisen über einen Schwenkbolzen schwenkbar an einem Rotor der Zerkleinerungsmaschine befestigt wird. Im Hammerschlageisen ist ein Einsatzstück mit einer Aufhahmeöffnung für den Schwenkbolzen vorgesehen, das in einer ersten Orien- tierung oder in einer zweiten Orientierung eingebaut werden kann. Die Aufnah- meöffnung definiert eine erste Anlagefläche für den Schwenkbolzen in der ersten Orientierung des Einsatzstücks und eine zweite Anlagefläche für den Schwenkbolzen in der zweiten Orientierung des Einsatzstücks. Die erste Anlagefläche in der ersten Orientierung des Einsatzstücks hat einen anderen Abstand zum Ham- merkopf (und damit zum Amboss) als die zweite Anlagefläche in der zweiten Orientierung des Einsatzstücks. The object of the invention is to provide improved hammered irons for a shredding machine of the type mentioned, which have a longer service life to reduce operating costs, without negatively affecting the quality of the shredded product. This object is solved by the invention which is defined in the independent claims; Embodiments of the invention are defined in the dependent claims. To solve this problem, the invention discloses hammered irons for a crushing machine with a fixed anvil, wherein the hammered iron is pivotally mounted on a pivot pin on a rotor of the crushing machine. In Hammerschlageisen an insert is provided with a receiving opening for the pivot pin, which can be installed in a first Orientation or in a second orientation. The receiving opening defines a first contact surface for the pivot pin in the first orientation of the insert and a second contact surface for the pivot pin in the second orientation of the insert. The first contact surface in the first orientation of the insert has a different distance to the Ham- head (and thus the anvil) as the second contact surface in the second orientation of the insert.
In einer Ausführungsform weist der Hammer ein Einsatzstück auf, das den Schwenkbolzen, mittels dessen der Hammer am Rotor schwenkbar befestigt ist, durch eine einfache, zylindrische Bohrung aufnimmt, die in Längsrichtung des Einsatzstückes außermittig angebracht ist und einander gegenüberliegende Anlageflächen definiert. In one embodiment, the hammer has an insert which receives the pivot pin by means of which the hammer is pivotally mounted on the rotor through a simple, cylindrical bore which is eccentrically mounted in the longitudinal direction of the insert and defines opposed abutment surfaces.
In einer weiteren Ausführungsform wird der Schwenkbolzen durch einen Lang- lochschlitz geführt, der in Längsrichtung des Einsatzstückes außermittig angebracht ist und einander gegenüberliegende Anlageflächen definiert. In a further embodiment, the pivot pin is guided through a slot slot, which is mounted off-center in the longitudinal direction of the insert and defines opposing contact surfaces.
In beiden Ausführungsformen ist das längliche oder ovale Einsatzstück in Längserstreckung des Hammers auswechselbar eingebaut. Die Lage der in Längsrich- tung außermittig in das Einsatzstück zur Aufnahme des Schwenkbolzens eingebrachten Bohrung oder des in Längsrichtung außermittig eingebrachten Langlochs bestimmt die unterschiedlichen Dicken der beiden endseitigen Wangen des Einsatzstücks; die auf den Hammerkopf zuweisende Innenseite der Bohrung oder des Langlochs bildet eine Anlagefläche, an der der Schwenkbolzen im ausgeschwenk- tem Betriebszustand des Hammers anliegt. Die beiden Wangen befinden sich in Längsrichtung am jeweiligen Ende eines Einsatzstückes. In both embodiments, the elongated or oval insert is interchangeable installed in the longitudinal extent of the hammer. The position of the longitudinally eccentrically introduced into the insert for receiving the pivot pin bore or longitudinally eccentrically introduced slot determines the different thicknesses of the two end cheeks of the insert; The inner side of the bore or slot, which points towards the hammer head, forms a contact surface on which the pivot pin rests in the swung-out operating state of the hammer. The two cheeks are located in the longitudinal direction at the respective end of an insert.
Die außermittige Bohrung ist derart auszuführen, dass der Abstand der Bohrungsinnenwand zum benachbarten Endpunkt des Einsatzstückes unterschiedlich groß ist, gesehen in der Längsrichtung des Einsatzstückes und der bei der Rotation auftretenden Zentrifugalkraft. Entsprechendes gilt für das Langloch. Entscheidend hierbei ist, dass beim Drehen des Einsatzstückes im Hammer um 180°die Distanz zwischen Hammerkopf und Anlagefläche verändert wird, und damit bei eingebautem Hammer auch die Distanz zwischen Hammerkopf und Amboss. Diese Forderung ist sowohl bei der zylindrischen Bohrung als auch beim The off-center bore is to be designed such that the distance of the bore inner wall to the adjacent end point of the insert is different in size, seen in the longitudinal direction of the insert and the centrifugal force occurring during the rotation. The same applies to the slot. Crucial here is that when turning the insert in the hammer by 180 °, the distance between the hammer head and contact surface is changed, and thus with built-in hammer, the distance between the hammer head and anvil. This requirement is both in the cylindrical bore and in the
Langloch zu erfüllen. Dazu weist das Einsatzstück an gegenüber liegenden Enden Wangen unterschiedlicher Dicke auf. Bei ausgeschleudertem Hammer liegt die Anlagefläche einer Wange des Einsatzstücks am Schwenkbolzen an und bestimmt den Abstand des Hammerkopfes zum Amboss. Durch das Anliegen der einen Wange des Einsatzstückes am Schwenkbolzen ist die Bewegung des Hammers in Richtung Amboss begrenzt. Die beiden gegenüberliegenden Wangen des Einsatzstückes sind sowohl bei einer zylindrischen, außermittigen Bohrung als auch bei einem außermittigen Langloch von unterschiedlicher Dicke. Damit definieren sie unterschiedliche Abstände für den Hammerkopf zum Amboss, je nachdem an welcher Wange des Einsatzstücks der Schwenkbolzen zur Anlage kommt. Long hole to meet. For this purpose, the insert at opposite ends cheeks of different thickness. When ejected hammer the contact surface of a cheek of the insert abuts the pivot pin and determines the distance of the hammer head to the anvil. By the concern of a cheek of the insert on the pivot pin, the movement of the hammer in the direction of the anvil is limited. The two opposite cheeks of the insert are different in both a cylindrical, off-center bore and an off-center slot. Thus, they define different distances for the hammer head to the anvil, depending on which cheek of the insert of the pivot pin comes to rest.
Dadurch, dass die beiden Wangen entweder eine zylindrische, außermittige Bohrung oder ein außermittiges Langloch in einem Einsatzstück begrenzen, genügt eine 180° Drehung des Einsatzstückes im Hammer, um die Distanz zwischen Hammerkopf und Amboss zu variieren. Entspricht daher im Neuzustand des Hammers eine größere Dicke einer Wange des Einsatzstückes dem gewünschten Spalt zwischen Amboss und Hammerkopf, dann entspricht nach dem Drehen des Einsatzstücks um 180° das Anliegen des Schwenkbolzens an der anderen, dünne- ren Wange wieder dem gewünschten Nenn-Abstand zwischen Amboss und Hammerkopf auch nach einem Verschleiß am Hammerkopf. The fact that the two cheeks define either a cylindrical, off-center hole or an off-center slot in an insert, a 180 ° rotation of the insert in the hammer is sufficient to vary the distance between the hammer head and anvil. Corresponds therefore in the new state of the hammer, a greater thickness of a cheek of the insert the desired gap between anvil and hammer head, then corresponds to the rotation of the insert by 180 °, the concerns of the pivot pin on the other, thinner cheek again the desired nominal distance between Anvil and hammer head even after a wear on the hammer head.
Das Einsatzstück ist auswechselbar im Hammer vorgesehen, entweder in einem Passsitz oder befestigt durch übliche Befestigungsmittel. Um die Zuordnung von Schwenkbolzen und Wange, bzw. Anlagefläche den Notwendigkeiten zwischen Neuzustand und abgenutztem Hammer anzupassen, genügt es nach der Erfindung, das Einsatzstück auszubauen und um 180° gedreht wieder in den Hammer einzubauen. Infolge einer dünneren Wange kann der Hammer dann wiederum so nahe an den Amboss geschleudert werden, dass ein Spalt zwischen Amboss und Ham- merkopf gebildet wird, der dem Nennmaß entspricht, das von einem neuen Hammer gebildet würde. Bei entsprechender Anzahl von Einsatzstücken mit unterschiedlichen Wangendicken kann somit adäquat auf Hammerverschleiß reagiert werden. Es ist zweckmäßig, Einsatzstücke mit unterschiedlichen Wanddicken der Wangen vorrätig zu halten, damit der Einsatzbereich eines einzelnen Hammers und seiner Standzeit optimal ausgeschöpft werden können. The insert is replaceable provided in the hammer, either in a snug fit or fastened by conventional fasteners. In order to adapt the assignment of pivot pin and cheek, or contact surface to the needs between new condition and worn hammer, it is sufficient according to the invention to remove the insert and rotated by 180 ° to re-install in the hammer. As a result of a thinner cheek, the hammer can then again be thrown so close to the anvil that a gap is formed between the anvil and the hammer head, which corresponds to the nominal size that would be formed by a new hammer. With appropriate number of inserts with different cheek thicknesses can thus be adequately responded to hammer wear. It is useful to keep inserts with different wall thicknesses of the cheeks in stock, so that the range of application of a single hammer and its life can be optimally utilized.
Darüber hinaus bewirkt die Erfindung nicht nur eine verlängerte Standzeit für einen Hammer, sondern hat auch bei Einsatzstücken mit Langloch einen nicht unerheblichen Einfluss auf die Sicherheit der Maschine. Werden der Maschine übergroße oder harte Bauteile zum Zerkleinern zugeführt, so kann sich der im Langloch geführte Hammer, den Spalt zwischen Amboss und Hammerkopf vergrößernd, gegen die Fliehkräfte vom Amboss wegbewegen. Dies ist der zusätzliche Vorteil, wenn der Schwenkbolzen, um den sich der Hammer dreht, in einem Langloch eines Einsatzstückes im Hammer angeordnet ist. Bei einer zylindrischen, außermittigen Bohrung im Einsatzstück kann eine Zerstörung der Maschine nur dadurch vermieden werden, dass alle Bauteile äußerst massiv ausgestaltet sind, sodass der Hammer, gegen die Fliehkräfte, zurückgeschleudert werden kann. Ebenso ist es in diesem Falle wichtig, dass beim Beschi- cken der Maschine darauf geachtet wird, dass schwer zu zerkleinernde Teile nicht in die Maschine eingeführt werden. In addition, the invention not only causes a prolonged service life for a hammer, but also has a significant impact on the safety of the machine with inserts with slot. If the machine supplied oversized or hard components for crushing, so the guided in the slot hammer, the gap between the anvil and hammer head enlarging, move away from the anvil against the centrifugal forces. This is the added advantage when the pivot pin about which the hammer rotates is located in a slot of an insert in the hammer. In a cylindrical, eccentric hole in the insert destruction of the machine can only be avoided by all components are designed extremely solid, so that the hammer, against the centrifugal forces, can be thrown back. It is also important in this case that, when loading the machine, care is taken to ensure that parts that are difficult to cut are not inserted into the machine.

Ein oder mehrere Hämmer 4 sind jeweils zwischen zwei Scheiben an einem Schwenkbolzen eingehängt, gegebenenfalls unter Einsatz von Distanzringen. Entsprechende Anordnungen sind auch bei Zerkleinerungsmaschinen mit horizontal angeordneter Antriebsachse des Rotors einsetzbar. FIG. 1 shows a plan view of a vertical comminution machine, in which the drive axle 3a of the rotor 3 runs perpendicular to the plane of the drawing. On the drive axis of the rotor discs 3b are arranged one above the other, each having openings for fixing the pivot pin 6. One or more hammers 4 are each suspended between two discs on a pivot pin, optionally with the use of spacers. Corresponding arrangements can also be used in comminution machines with horizontally arranged drive axle of the rotor.
Der an einem Maschinengestell 1 fest montierte Amboss 2 wirkt im Betrieb mit dem Hammerkopf 5 eines Hammers 4 zusammen. Entsprechend Fig. 3 ist zwischen Amboss 2 und dem Hammerkopf 5 ein Spalt 10 belassen. Dieser Spalt 10 vergrößert sich durch Abnutzung des Hammerkopfs 5. Dieser Spalt 10 ist für den Feinheitsgrad des zerkleinerten Materials von Bedeutung. Im Neuzustand des Hammers ist das Einsatzstück so montiert, dass im Betrieb der Schwenkbolzen 6 an der Innenseite der dickeren Wange 12 des Einsatzstücks 7 anliegt. Die dieser Wange 12 gegenüberliegende dünnere Wange 8 im Einsatzstück 7 ist dabei unbelastet. Die Dicke (b) der Wange 12, gemessen zum benachbarten Ende des Einsatzstückes 7, ist grösser als die Dicke (a) der gegenüber liegenden Wange 8, ebenfalls gemessen zu dem dieser Wange 8 benachbarten Ende des Einsatzstückes 7. Der Unterschied in der Dicke der beiden gegenüberliegenden Wangen 8; 12 entspricht dem Maß an Verschleiß am Hammerkopf 5, bei dem ein Ersetzen des Hammers 4 durch einen neuen Hammer notwendig gewesen wäre. The fixedly mounted on a machine frame 1 anvil 2 acts in operation with the hammer head 5 of a hammer 4 together. According to FIG. 3, a gap 10 is left between the anvil 2 and the hammer head 5. This gap 10 increases due to wear of the hammer head 5. This gap 10 is important for the degree of fineness of the crushed material. When the hammer is new, the insert is mounted in such a way that, during operation, the pivot pin 6 bears against the inside of the thicker cheek 12 of the insert 7. The cheek 12 opposite thinner cheek 8 in the insert 7 is unloaded. The thickness (b) of the cheek 12, measured to the adjacent end of the insert 7, is greater than the thickness (a) of the opposite cheek 8, also measured at the end of the insert 7 adjacent to this cheek 8. The difference in the thickness of the two opposite cheeks 8; 12 corresponds to the amount of wear on the hammer head 5, in which a replacement of the hammer 4 would have been necessary by a new hammer.
Das Einsatzstück 7 ist über Befestigungsmittel 9 oder über einen Passsitz auswechselbar mit dem Hammer 4 verbunden. Das Einsatzstück 7 weist längs seiner Mittellinie ein Langloch 11 auf, das durch die Wangen 8; 12 am Ende des Einsatzstücks begrenzt ist und den Schwenkbolzen 6 aufnimmt. Der Schwenkbolzen 6 ist seinerseits fest mit zwei benachbarten Scheiben 3 b des Rotors 3 verbunden. Bei einem neuen Hammer liegt der Schwenkbolzen 6 an der dickeren Wange 12 mit der Dicke (b) des Einsatzstücks 7 an und es entsteht ein Spalt 10 mit The insert 7 is interchangeable connected via fastening means 9 or a snug fit with the hammer 4. The insert 7 has along its center line on a slot 11 which through the cheeks 8; 12 is limited at the end of the insert and the pivot pin 6 receives. The pivot pin 6 is in turn firmly connected to two adjacent discs 3 b of the rotor 3. In a new hammer, the pivot pin 6 is located on the thicker cheek 12 with the thickness (b) of the insert 7 and there is a gap 10 with
Nennmaß zwischen Hammerkopf 5 und Amboss 2. Vergrößert sich der Spalt 10 durch Verschleiß am Hammerkopf 5, so kann der Spalt wieder auf Nennmaß zurückgeführt werden, indem man das Einsatzstück 7 ausbaut und um 180° geschwenkt wieder einbaut, sodass der Schwenkbolzen 6 beim Betrieb an der Innenseite der dünneren Wange 8 mit der Dicke (a) anliegt; beträgt beispielsweise der Verschleiß 0,3 mm, so wird ein Einsatzstück gewählt, bei dem sich die Dicken der beiden Wangen entsprechend unterscheiden, d.h. b-a = 0,3 mm. Nominal size between the hammer head 5 and anvil 2. If the gap 10 increases due to wear on the hammer head 5, the gap can be returned to nominal size by dismantling the insert 7 and pivoted back through 180 °, so that the pivot pin 6 is in operation the inside of the thinner cheek 8 with the thickness (a) is applied; For example, if the wear is 0.3 mm, an insert is selected in which the thicknesses of the two cheeks are different, i. e. b-a = 0.3 mm.
Die Figuren 2 und 3 zeigen das Einsatzstück 7 mit Orientierung entsprechend einem neuen Hammer, so dass der Schwenkbolzen beim Betrieb an der dickeren Wange 12 anliegt. Figures 2 and 3 show the insert 7 with orientation corresponding to a new hammer, so that the pivot pin rests against the thicker cheek 12 during operation.
Die Figuren 4 und 5 zeigen ein zweites Ausführungsbeispiel eines Hammers gemäß der Erfindung für eine Zerkleinerungsmaschine der eingangs genannten Art. An einem Maschinengestell ist ein Amboss 12 fest montiert und wirkt im Betrieb mit dem Hammerkopf 5 eines Hammers 14 zusammen. Zwischen Amboss 12 und dem Hammerkopf 5 ist ein Spalt 010 belassen. Dieser Spalt 010 vergrößert sich durch Abnutzung des Hammerkopfs 5. Dieser Spalt 010 ist für den Feinheitsgrad des zerkleinerten Materials von Bedeutung. Beim Betrieb im Neuzustand des Hammers liegt der Schwenkbolzen 16 an der dickeren Wange 012 des Einsatzstücks 17 an. Die dieser Wange 012 gegenüberliegende Wange 18 im Einsatzstück 17 ist dabei unbelastet. Die Dicke (bb) der Wange 012, gemessen zum benachbarten Ende des Einsatzstückes 17, ist grösser als die Dicke (aa) der gegenüber liegenden Wange 18, ebenfalls gemessen zum benachbarten Ende des Einsatzstückes 17. Der Unterschied in der Dicke der beiden Wangen 18; 012 entspricht dem Maß an Verschleiß am Hammerkopf 5, bei dem ein Ersetzen des Hammers 14 durch einen neuen Hammer 14 notwendig gewesen wäre. Figures 4 and 5 show a second embodiment of a hammer according to the invention for a crushing machine of the type mentioned. On an engine frame, an anvil 12 is fixedly mounted and acts in operation with the hammer head 5 of a hammer 14 together. Between the anvil 12 and the hammer head 5, a gap 010 is left. This gap 010 increases due to wear of the hammer head 5. This gap 010 is important for the degree of fineness of the comminuted material. When operating in the new state of the hammer, the pivot pin 16 abuts against the thicker cheek 012 of the insert 17. The cheek 012 opposite cheek 18 in the insert 17 is unloaded. The thickness (bb) of the cheek 012, measured to the adjacent end of the insert 17, is greater than the thickness (aa) of the opposing cheek 18, also measured to the adjacent end of the insert 17. The difference in thickness of the two cheeks 18; 012 corresponds to the amount of wear on the hammer head 5, in which a replacement of the hammer 14 would have been necessary by a new hammer 14.
Das Einsatzstück 17 ist auswechselbar und passgenau im Hammer 14 fixiert, z.B. mit Befestigungsmitteln. Das Einsatzstück 17 weist eine zylindrische Bohrung 011 auf, die außermittig in Längsrichtung des Einsatzstücks 17 vorgesehen ist, sodass durch die jeweilige Wange 18; 012 unterschiedlicher Dicke, der Abstand des Hammerkopfes 5 zum Amboss 12 geändert werden kann, wenn das auswechselbare längliche Einsatzstück 17 um 180° gedreht wird. Durch die zylindrische Bohrung 01 1 ist der Schwenkbolzen 16 geführt, der an den Rotorscheiben 13b des Rotors befestigt ist. Im Betrieb mit einem neuen Hammer liegt der Schwenkbolzen 16 an der Innenseite der Wange 012 des Einsatzstücks 1 7 an und erzeugt einen Spalt 010 zwischen Hammerkopf 5 und Amboss 12 mit Nennmaß, entsprechend einer Wangendicke (bb) im Einsatzstück 17. Vergrößert sich der Spalt 010 durch Verschleiß am Hammerkopf 5, so kann der Spalt 010 wieder auf das gewünschte Nennmaß zurückgeführt werden, wenn man das Einsatzstück 17 ausbaut und um 180° geschwenkt wieder einbaut, sodass der Schwenkbolzen 16 bei Betrieb an der Wange 18 mit der geringeren Dicke (aa) anliegt; ein Verschleiß des Hammerkopfes von beispielsweise 0,3 mm kann ausgeglichen werden, wenn ein Einsatzstück mit den Wangendicken (aa), (bb) entsprechend bb-aa= 0,3 mm mit umgekehrter Orientiemng wieder eingebaut wird. The insert 17 is interchangeable and accurately fixed in the hammer 14, for example with fasteners. The insert 17 has a cylindrical bore 011, which is provided off-center in the longitudinal direction of the insert 17, so that through the respective cheek 18; 012 different thickness, the distance of the hammer head 5 to the anvil 12 can be changed when the replaceable elongated insert 17 is rotated by 180 °. Through the cylindrical bore 01 1 of the pivot pin 16 is guided, which is fixed to the rotor discs 13 b of the rotor. In operation with a new hammer, the pivot pin 16 bears against the inside of the cheek 012 of the insert 17 and creates a gap 010 between the hammer head 5 and the anvil 12 of nominal size, corresponding to a cheek thickness (bb) in the insert 17. The gap 010 increases due to wear on the hammer head 5, the gap 010 can be returned to the desired nominal size if the insert piece 17 is removed and installed swiveled through 180 °, so that the pivot pin 16, when operated on the cheek 18, has the smaller thickness (aa). bears; a wear of the hammer head, for example, 0.3 mm can be compensated if an insert with the cheek thickness (aa), (bb) corresponding to bb-aa = 0.3 mm with reverse Orientiemng is reinstalled.
Die Figuren 4 und 5 zeigen das Einsatzstück 17 mit Orientierung entsprechend einem Hammer mit Verschleiß, so dass der Schwenkbolzen beim Betrieb an der dünneren Wange 18 anliegt. Figures 4 and 5 show the insert 17 with orientation corresponding to a hammer with wear, so that the pivot pin rests against the thinner cheek 18 during operation.
Vorzugsweise wird das Einsatzstück (7; 17) aus hochfestem Stahl gefertigt. Die Anlageflächen für den Schwenkbolzen (6; 16) können zusätzlich gehärtet werden. Vorzugsweise werden in den Anlageflächen Schmierbohrungen vorgesehen, die mit einer zentralen Schmiereinrichtung verbindbar sind. Preferably, the insert (7; 17) is made of high strength steel. The contact surfaces for the pivot pin (6; 16) can be additionally hardened. Preferably, lubrication holes are provided in the contact surfaces, which are connectable to a central lubrication device.
In anderen Ausfuhrungsformen der Erfindung können Einsatzstücke verwendet werden, die auch bei einer Drehung im Hammer um weniger als 180° unterschied- liehe Anlageflächen für den Schwenkbolzen definieren, beispielsweise rotationssymmetrische Einsatzstücke mit einer außermittigen Bohrung für den Schwenkbolzen. In other embodiments of the invention insert pieces can be used which define even with a rotation in the hammer by less than 180 ° different Liehe contact surfaces for the pivot pin, for example rotationally symmetrical inserts with an off-center bore for the pivot pin.
