    The invention relates to a shearing blade according to the preamble of claim 1
    In cutters, a known embodiment is to form the cutters so that they comprise a cutter blade main body and arranged on this or used blade insert. In particular, in cutters used for salvage operations or demolition work, the shearing blades are exposed to harsh operating conditions. Therefore, the shearing blade bodies are preferably made of tough material, while the blade inserts are preferably formed by a hard material with good cutting action and low wear. In the case of damage to the cutting edge in such an embodiment, not the entire shearing blade must be replaced, but it is sufficient if the defective blade insert is replaced. Merely replacing the blade insert causes significantly lower costs than replacing the entire shearing blade, which is why such shear blades represent an economically advantageous design.
    A recovery device with a shearing blade constructed from a shearing blade main body and a blade insert inserted therein is known, for example, from DE 20 2004 011 263 U1 or GB 2 254 580 A. The blade inserts are fixed to the base of these blades by means of five or three fastening screws. However, this way of mounting the measuring inserts is relatively complex, as are voizusehen either in the main body or in the blade insert internal thread and further the change of such blade inserts is cumbersome and time consuming, especially if the required tools can not be easily attached to the mounting screws due to contamination or mechanical damage during use , 27/05/2011 16:23

    The object of the invention is to improve the attachment of a blade insert in a blade base body so that both the production of the individual components and the replacement of knife elements is facilitated.
    The Aulgabe of the invention is achieved by a generic cutter with the characterizing features of claim 1.
    Characterized in that the seat has an effective in the direction transverse to the free surface undercut surface which cooperates with inserted blade insert with a form-fitting surface formed on it and thereby a transversely acting to the free surface form-fitting is made and that the blade insert by means of a transverse to the free surface oriented in aligned holes arranged in the base body and the knife insert, pin-shaped connector element is attached to the body, resulting in a stable fit of the blade insert on the body, which can be secured without the use of screw and is structurally simple.
    The at least one undercut surface on the base body and / or the at least one interlocking surface on the blade insert can extend over the entire edge of the blade insert or the seat in the base body or else only be executed in sections. The connector element can be formed by an easily available and inexpensive standard component and are further the holes for receiving the connector element on the body as well as the blade insert produced with little effort. Since forces are transmitted transversely to the free surface mainly between positive surface and undercut surface, it is no disadvantage that a connector element can transmit only low tensile forces, and is sufficient for a reliable fixation of the blade insert in the blade a small number of such connector elements. Preferably, the blade insert is fixed with only two connector elements on the base body. For inserting a plug-in connection element preferably the bore on the main body extends from the seat to the outside of the main body and becomes N2011 / 1550097 / n (wnn ir- 4

    If the end sections or the end-face surfaces of the blade insert have positive-locking surfaces which interact with undercut surfaces on the base body, a blade insert can alternatively or additionally be secured at its ends against being pulled out of the seat on the base body transversely to the free surface. The forces to be transmitted by the connector elements decrease accordingly. In particular, the undercut surfaces for the end sections of the blade insert can have the same profile in cross-section as the undercut surfaces for the middle section of the blade insert. As a result, the undercut of the seat can be made on the main body both for the central part of the blade insert as well as for the end portions with a single tool in one clamping.
    A favorable embodiment is that the undercut surface is formed by half a dovetail groove in the base body and the knife insert salt used has a parallelogram-like cross-section and forms the form-fitting surface together with an approximately parallel to the free surface bearing surface of the cutting edge opposite, acute-angled Formschluss-speed forms in the Dovetail groove engages while the undercut surface engages behind. A positive connection between the blade insert and the base body by a dovetail-like connection is easy to manufacture and has the positive locking wedge in the base body a stable seat and is well secured against withdrawal right angles or across the open space. By the connector element whose orientation deviates from the direction of the undercut surface, a sliding out of the blade insert is reliably prevented.
    Advantageous conditions for the power transmission between the blade insert and the base body is given when the positive-engagement key has a wedge angle between 45 ° and 80 °. N2011 / 15500 17 / ns / im 1 1 9 / i Wr RR1Δ P. 007/027 -4- 25 -4- 25 8/27 16:23:47 27-05-2011
    An alternative embodiment of the seat is given by when the undercut surface is formed by half a T-slot in the body and the positive surface is formed on the blade insert by a T-groove engaging behind Falzansatz. Also, this embodiment is manufacturing technology relatively easy to manufacture and is the blade insert with inserted plug connector transversely to the free surface relative to the body not displaced.
    If the hole for receiving the connector element in the blade insert extends to the free surface, the plug connection element can be easily expelled from the open space to replace the blade insert.
    In order to prevent that the end of the connector element unintentionally can escape from the blade insert beyond the free surface during use, it is advantageous if the hole in the blade insert in the area of the free surface has a smaller, stepped stepped diameter or another constriction in the Has bore cross-section.
    A reinforced in practice and economical embodiment is that the connector element is formed by a dowel pin in the form of a hollow, longitudinally slotted pin Such a dowel pin can compensate for its flexibility in the diameter direction component geometries and is for fixing the blade insert on the seat a structurally simple and reliable Solution. Furthermore, the connector element may be formed by a spiral tension pin, a grooved pin, or a cylindrical pin, all of these variants allow the saving of internal threads on the components.
    A further increase in stability is achieved when the dowel pin is reinforced by another inserted in its hollow interior further connector element. This may be of the same or other design, as the outer connector element.

    A manufacturing technology easily manufacturable embodiment is given if the central axis of the connector element is rechtwinkeiig oriented to the open space. As a result, the connector element is in any case angled to the undercut surface and thus ensures the necessary fixation of the blade insert. At the same time, the connector element can transmit all the shear forces occurring transversely to its center axis in all directions.
    A uniform force transmission between the blade insert and the base body is achieved when the seat on the base body for the back or the back of the blade insert is formed essentially of flat surfaces. Such an embodiment of the seat can be produced by a straight milling movement of a corresponding milling cutter and is thereby ensured in the middle part of the blade insert a uniform contact and a stable, planar support on the body.
    If the direction of the center axis of the connector element differs by an angle of at least 10 "from the direction of the undercut surface, a sufficient fixation of the blade insert in the seat is given because a displacement parallel to the undercut surface is prevented by the shear resistance of the connector element.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Fig. 1 shows an oblique view of cutting device 1, as it is often used for the recovery of injured persons from vehicles or for other purposes such. Demolition work is used. This comprises two of a drive, not shown, for example, a hydraulic cylinder, driven razors 2, which are hinged to a frame of the cutter 1 and are used for cutting through a variety of materials by shear cutting. The shearing blades 2 comprise a base body 3 with a seat on which a blade insert 4 is arranged or inserted. The seat has a special, explained with reference to further figures embodiment with an undercut, a positive connection between blade insert 4 and base N2011 / 15500 θ7 / ης / οηιι 1rOft

    In the illustrated embodiment, the blade inserts 4 and the shearing blades 2 have curved cutting edges 6, which may have advantages for the cutting process. The backs 7 of the blade inserts 4, however, are rectilinear, whereby a reliable, uniform contact with the base body 3 is achieved. The blade inserts 4 are preferably inserted into the base body 3 such that flush transitions to the base body 3 are provided.
    The main body 3 of a shearing blade 2 is preferably formed of a tough steel, which can endure even hard impact loads. However, it is also a weight-saving design of the body made of lighter metals than steel conceivable. The blade insert 4 of such a blade 2, however, is made of a hard as possible material with good cutting properties, thereby cutting even of harder materials is made possible.
    Fig. 2 shows a detail of a cross section along line ll-ll in Fig. 3 by a shearing blade 2, in which in a base body 3, a blade insert 4 is inserted. The shearing blade 2 shown in Fig. 3 in view according to arrow III in Fig. 2 may relate to the same embodiment of a shearing blade 2 as in Fig. 2, but also an embodiment in which no undercut is provided on the back 7 of the blade insert 4. Likewise FIG. 2 shows an embodiment in which an undercut is provided only on the rear side 7, but not on the ends of the blade insert 4.
    The cutting edge 6 is formed by a cutting wedge 8 which in turn is formed by an intersection of an open space 9 and a pressure surface 10. In a cutting operation, the shearing blade 2 which is oriented upwards in FIG. 2 cooperates with a second shearing cutter, not shown, whereby the free surfaces 9 are moved past each other at a small distance from one another. The cutting wedges 8 penetrate into a not shown, to be cut through an object, wherein the pressure surfaces 10 press on the surface of the object and in consequence a separation of the object takes place.

    The surfaces on which the blade insert 4 contacts the main body 3 form a seat 11, wherein in the embodiment shown in FIG. 2 the seat 11 comprises an abutment surface 9 approximately parallel to the contact surface 12 and an undercut surface 13 arranged at an acute angle thereto. The blade 11 corresponds in Fig. 2 a half dovetail groove 14. The blade insert 4 is approximately paralielogrammförmig in cross-section and is located with a free surface 9 approximately parallel contact surface 15 on the contact surface 12 of the body and with a positive surface 16 on the undercut surface 13 of the dovetail groove 14 on. The form-fitting surface 16, together with the contact surface 15 on the blade insert 4, forms an acute-angled positive-locking wedge 17, which lies approximately opposite the cutting edge 6 and engages in the dovetail groove 14. Of course, the form-fitting wedge 17 may have a different wedge angle than the cutting wedge 8, but an angle between 45 ° and 80 ", for example 60 °, has proved to be advantageous. The cross section of the blade insert 4 need not be paralielogrammförmig, as shown, but may of course have a deviating contour, if the seat 11 kn body 3 is carried out accordingly.
    The knife insert 4 inserted in the seat 11 is further connected to the main body 3 by a plug connection element 5, which is arranged in a bore 18 in the base body 3 and a bore 19 aligned in the knife insert 4. in dargesteilten embodiment, the central axis 20 of the connector element 5 is oriented at right angles to the free surface 9, but may also have a deviating orientation. To achieve a secure positive connection of the blade insert 4 in the base body 3, however, it is important that the central axis 20 of the plug connection element 5 is different by an angle of at least 20 ° from the direction of Hinterschneidungsfiäche 13.
    The plug connection element 5 is fixed in the bores 18 and 19 by a press fit, for which purpose the plug connection element 5 in the unmounted state has a slightly larger diameter than the bores 18 and 19, respectively.

    Clamping pin 21 executed, which has the form of a hollow, longitudinally slotted pin. Through the longitudinal slot, it has a certain elasticity in the radial direction, which facilitates or permits the pressing into the bores 16, 19, even if the center axes of the bores are not precisely aligned due to manufacturing tolerances.
    The pressing-in of the plug-in connection element 5 preferably takes place from the rear side 22 of the shearing blade 2, for which purpose the bore 18 completely penetrates the base body 3 from the rear side 22 to the seat 11 or to the contact surface 12. To allow easy disassembly of the inserted connector element 5, the bore 19 passes through the blade insert 4 completely, whereby the connector element 5 can be easily expelled again.
    The central axis 20 of the plug connection element 5 deviates from the direction 23 of the undercut surface 13 by an angle 24 which is preferably at least 10 °, e.g. about 30 °.

FIG. 3 shows that the additionally or alternatively the end sections 26 of the blade insert 4 can have form-locking surfaces 27 which engage with undercut surfaces 28 on the base body 3 cooperation. The end portions 26 and the ends of the blade insert 4 have thereby a positive connection in the direction transverse to the free surface 9 in the illustrated embodiment as well as in the example of FIG. 2 by cooperation of a positive wedge 17 is effected with a dovetail groove 14. Preferably, the undercut surfaces 28 for the end portions 26 have the same profile in cross section as the undercut surfaces 13 for the central portion 25 of the blade insert 4, whereby the seat 11 can be made in the base body 3 in a single set up with a single cutter. The transition between the back 7 of the blade insert 4 and its ends is rounded in this case.

    The embodiment of the shearing blade 2 according to FIGS. 4 and 5 is similar to the embodiment shown in FIGS. 2 and 3, and here too the blade insert 4 has a positive connection in the base body 3 transversely to the free surface Θ. The seat 11 on the base body 3 has for this purpose a half T-slot 29 into which engages when a blade insert 4 inserted a Falzansatz 30. In this case, the T-groove 29 forms the undercut surface 13, which is engaged behind by the mold face 16 of the engaged seam attachment 30. Hinterschneidungsfiäche 13 and interlocking surface 16 are executed in the embodiment of FIG. 4 parallel to the free surface 9, but can of course also have deviating angles. It is advantageous if, as shown in Fig. 5, also at the end portions 26 of the blade insert 4 a positive connection in the base body 3 is made and the blade insert 4 not only on its back 7, but also on its end faces of the end portions 26 in the base body. 3 is positively secured. FIG. 5 shows that dis acting on the end faces of the blade insert 4 positively locking surfaces 27 and the seat 11 with the undercut surface 28 in the base body 3 may have the same cross section as the cross section shown in Fig. 4 with positive engagement surface 16 and undercut surface 13 in the middle part 25 of the blade insert 4, whereby a milling of the seat 11 in a single setup is possible.
    The positive connection of the blade insert 4 in the base body 3 transversely to the free surface 9 is preferably given both on the back 7 and at the end portions 26 and their spaced in the direction of the cutting edge faces, but it is also possible that the positive connection only at the end portions 26th o-which is provided only on the back 7 of the blade insert 4.
