Definitions
- Cutter head in particular planer cutter head
- the invention relates to a cutter head, in particular a planer cutter head, with the features of the preamble of claim 1.
- a known cutter head of the type mentioned for processing wood has a support body which is provided with several receptacles for knives along its circumference at equal intervals.
- the receptacles are open radially outwards and extend parallel to the axis of rotation of the support body.
- a pressure jaw movable relative to the supporting body and the respective knife is provided in each receptacle.
- the invention is therefore based on the object of improving a cutter head of the type described at the outset. This object is achieved according to the invention by a cutter head with the features of claim 1.
- the knives can be used for Turning or resharpening of the cutter head, without having to remove it, can also be removed if the end faces are not or not sufficiently accessible.
- the stop is designed as an exchangeable stop bar in order to be able to vary the size of the rake face of the knife lying radially outside the stop bar and / or the chip space.
- the knife advantageously has a groove in its chest, the depth of which is selected to be equal to this maximum material removal.
- the support body from aluminum.
- Fig. 1 is an end view of the embodiment in the prestressed
- FIG 3 shows a section, only partially shown, of the exemplary embodiment in the released state in the plane of a compression spring.
- a planer cutter head for processing wood or plastic has a support body 1 made from a cylinder, which is provided with a central through bore 3 for receiving a shaft. The center of the Through hole 3 defines the axis of rotation of the support body 1.
- the support body 1 is preferably made of aluminum.
- the support body 1 has two mutually opposite, groove-like receptacles 5, which are open radially outwards and extend parallel to the axis of rotation of the support body 1.
- the planer knife head according to the invention can also have a different number of receptacles, the receptacles being provided at equal intervals in the circumferential direction in order to avoid unbalances.
- Each existing receptacle 5 contains a device for clamping a knife 7 in each case.
- a stop bar 9 is provided on the flank of the receptacle 5 leading in the direction of rotation, which by means of a strip-shaped projection which preferably extends over the entire length of the stop bar 9 in a corresponding, groove-like recess of the support body 1 engages and is firmly but releasably connected to the latter by screws, not shown in the drawing.
- the stop bar 9 can also be formed in one piece with the support body 1.
- the stop bar 9 serves on the one hand as a stop for the tensioning device for the knife 7.
- the stop bar 9 has a flat stop surface 11 against which the knife 7 with its breast 13 can rest.
- the stop bar 9 with its radially outer end is part of the delimitation of the chip space 15, which is formed in the direction of rotation in front of the receptacle 5 as a groove in the outer jacket of the supporting body 1.
- the part of the breast 13 which projects beyond the stop bar 9 forms the rake face 13 'of the knife 7.
- the cutting edge 7' of the knife is formed by that end of the rake face 13 'with the greatest distance from the axis of rotation of the support body 1 which thus also defines the radius of the flight circle.
- the chip break occurs at the transition between the rake face 13 'and the stop bar 9.
- the chip flow takes place into the chip space 15.
- a further part of the clamping device is a pressure jaw 17, which is movable along this flank with at least one component in the radial direction.
- the pressure jaw 17 has the shape of a wedge, which has a tapering end that points outwards from the receptacle 5.
- at least one clamping screw 19 is provided, which engages with the pressure jaw 17 in such a way that the pressure jaw 17 can be moved with play by means of this clamping screw 19 both inwards and outwards .
- the clamping screw 19 has an annular groove in its head, into which a projection of the pressure jaw 17 engages with little play.
- the pressure jaw 17 is in a radially outer position.
- a holder bar 21 is arranged as a knife holder and another part of the clamping device.
- the holder strip 21 lies flat against the pressure jaw 17 on its side lagging in the direction of rotation.
- the holder strip 21 has a positioning groove 23 on its leading side in the direction of rotation, into which the knife 7 engages with a positioning projection 25. Otherwise, the holder bar 21 lies flat against the back 27 of the knife 7.
- the assignment of the two positioning elements 23 and 25 to the knife 7 and the holder strip 21 could also be exactly the opposite.
- the positioning groove 23 and the positioning projection 25 are for absorbing a part of the centrifugal forces of the knife 7 rotating cutter head. They are therefore shaped in such a way that, in the pretensioned state, the knife 7 lies radially outward on the holder strip 21 and is immovable relative to it, that is to say it is held in a defined position.
- the holder bar 21 is shaped such that it engages under the stop bar 9 in the radial direction.
- the holder strip 21 with a radially outwardly oriented positioning surface 29 lies flat against a radially inwardly oriented contact surface 31 of the stop strip 9.
- the holder bar 21 also holds the knife 7 in a defined position relative to the stop bar 9.
- the contact point between the positioning surface 29 and the stop surface 21 is a plane which runs parallel to the free surface 33 of the knife 7.
- the pressure jaw 17 moves radially outwards, which allows the play between the clamping screw 19 and the pressure jaw 17.
- the centrifugal forces acting on the pressure jaw 17 are first deflected by the wedge shape onto the holder bar 21 and then onto the knife 7, whereby the knife 7 is pressed against the stop bar 9, that is to say it is tensioned.
- the centrifugal forces of the holder bar 21 and thus also of the knife 7 are transmitted to the stop bar 9 via said contact point.
- the position of the remaining parts of the clamping device relative to one another and relative to the knife 7 does not change in this tensioned state, except in the case of the pressure jaw 17.
- the relevant normal force for this friction is the clamping force of the clamping device, in particular the pressure jaw 17.
- the clamping screw 19 initially takes the pressure jaw 17 radially inwards.
- One or more compression springs 35 are provided between the pressure jaw 17 and the holder strip 21. Each compression spring 35 is supported in a blind hole in the pressure jaw 17 and is attached to the holder strip 21 at one end.
- This attachment point lies radially further inward than the contact point formed by the positioning surface 29 and the contact surface 31 between the holder strip 21 and the stop strip 9.
- the pressure spring 35 comes into effect by the movement of the pressure jaw 17 in such a way that it comes into play Exerts torque on the holder bar 21.
- the holder bar 21 pivots about an edge 29 'at the edge of the positioning surface 29.
- the edge 29' is the part of the holder bar 21 which extends under the stop bar 9 the furthest.
- the pivoting movement of the holder bar 21 is directed due to the position of the attachment point of the compression spring 35 so that the holder bar 21 moves away from the knife 7 towards the pressure jaw 17.
- the positioning surface 29 moves away from the contact surface 31, however the edge 29 'remains in linear contact with the contact surface 31.
- the dimensions, angles, movement paths or swiveling ranges of the positioning groove 23, the positioning projection 25, the pressure jaw 17 and the holder bar 21 are selected so that the holder bar 21 can pivot into a position in which it releases the knife 7, and this can be removed radially outwards.
- the removed knife 7 can be turned and reinserted, provided the knife 7 is symmetrical with respect to a longitudinal plane.
- the knife 7 therefore preferably has an approximately trapezoidal cross section.
- the removed knife 7 can be resharpened, whereby it is ground on its chest 13.
- the knife 7 has a groove 37 on its chest 1 3 as a display means for the maximum grinding depth on the bottom of which defines the plane up to which the breast 13 may be ground off.
- the parallelism between the free surface 33, the contact surface 31 and the positioning surface 29 in the tensioned and pretensioned state ensures that even after grinding the breast 13 due to the displacement of the holder strip 21 parallel to the free surface 33 when tensioning, the distance between the new cutting edge 7 'and the axis of rotation of the support body 1, that is to say the new radius of the flight circle, coincides with the old radius.
- the knife 7, the stop bar 9, the pressure jaw 17 and the holder bar 21 extend exactly like the receptacle 5 parallel to the axis of rotation of the supporting body 1, preferably over its entire length. For the production of these parts, it is advisable to use profile bars and saw them to the correct length.
