Definitions
- the invention relates to a knife holder for knife heads for woodworking. With such cutter heads is for a precise knife positioning important to a to achieve good work results, but also the Safety of the knife holder due to the high cutter head speeds and therefore the one acting on the clamped knife high centrifugal forces.
- a knife head is known from WO 94/03 311, in which the knife plates with the help of clamping plates in recesses of the base body are held such that the knife plate each with its rear surface on one in the recess of the Base body formed contact surface and the clamping plate by means of one inserted in the base body and in screwed the clamping plate against the Front surface of the knife plate is clamped to this against to clamp the contact surface of the base body, and the Tension screw is designed as a tension screw and radial inside the lower edge of the cutter plate Threaded hole of the clamping plate is screwed in.
- the knife plate is a dowel in the contact surface of the base body, which in one in the Grooved groove on the radially inner cutting edge intervenes.
- the radial securing of the knife plate against the centrifugal forces act in that the knife plate a ground in near its radially inner edge Has transverse groove, in which a corresponding Raised rib engages on the clamping plate.
- the clamping plate is formed radially on the inside with a bulge which corresponding recess radially within the contact surface of the base body engages for the knife plate, such that the clamping plate by a certain amount after loosening the clamping screw Dimension within the recess of the base body from the knife plate can be tilted away, creating the cross rib of the clamping plate comes out of engagement with the transverse groove of the knife plate and the Knife plate can be removed from the knife head, without completely unscrewing the clamping screw and removing the clamping plate is necessary.
- a disadvantage of the known arrangement is that in the cutter groove formed for radial securing, because this weakening the knife plate in the radially inner region and thus forms a potential fault line so that the necessary level of security not necessarily guaranteed is.
- the invention is therefore based on the object of a knife holder to create in cutter heads that are under warranty a greater degree of security and inserting the knife plates without completely loosening the Allows clamping screws and the clamping plates.
- the arrangement according to the invention has the advantage that in essentially without weakening the integrity of the knife plate in the radially inner area a positive radial Fuse is achieved, the radial securing means can take over the axial definition at the same time, and nevertheless removing and inserting the knife plates in the cutter head without completely removing the clamping screws and the clamping plates is possible, rather the clamping screws only to be loosened to a certain degree.
- Fig. 1 shows a section of a cutter head with a Base body 1, a recess 2 formed therein for receiving a knife plate 3 with the associated clamping plate 4, the radially outer part of the recess 2 as a flute serves, and with a dashed line as an invisible part Clamping screw 5, the screw holder from Simplification is not shown, and finally with dowel pins 6 for positioning the knife plates.
- the clamping screw 5 acts as a lag screw and is radial within the inner end of the knife plate 3 below this screwed into the clamping plate 4. While dressing the clamping screw is the clamping plate 4 against the Front of the knife plate 3 tensioned and tensions the knife plate with the back surface against the corresponding plane Contact surface of the base body 1.
- the clamping plate 4 engages with your bead-shaped radially inner end 4a into the tapered radially inner end the recess 2 and there is a hinge-like one small angular distance foldable.
- On the front is the Clamping plate 4 a nose 4b, which with play in a top through a projection 1 a limited recess 1 b in the base body intervenes.
- the clamping plate 4 a bit forward from the knife plate 3 or from this Tilt the supporting contact surface of the base body 1 away the tilting movement hinge-like on its radially inner one bead-like end 4a and the nose 4b a little further in immerses the recess 1b.
- the knife plate 3 can then as can be seen from Fig. 4, which loosened and shows the tilted position of the clamping plate 4, also tilted forward from the contact surface of the base body (this is also shown in Fig. 4) and then radial outwards, as indicated by the arrow, out of the knife head be pulled out.
- Recess in the base body 1 for receiving the clamping screw 5 is designed so that the correct support for tightening the clamping screw is guaranteed in loosened state the clamping screw 5 but together with the Clamping plate 4 somewhat in the relevant radial plane of the cutter head is tiltable.
- the knife insert 3 is shown in more detail in FIGS. 2 and 3 shown, namely in Fig. 2 perspective obliquely from rear, and in Fig. 3 in front view. As you can see, it is Knife plate 3 near its radially inner edge 3a with two lateral incisions 3b, in which in the cutter head inserted knife plate engage the dowel pins 6 and thus position the knife plate radially and axially and to back up.
- the cutting edge 3c of the knife plate 3 is located 3 and 4 above.
- the knife plate can also have for example a central hole-like opening and a recess corresponding to the recesses 3d can be made of this run to the radially inner edge 3a.
- cutouts 3d which are not in terms of their precision are critical, can already in the raw state of the knife plate 3 can be incorporated.
