Definitions

  • the present invention relates to a device for fixing hard metal knives on rotating knife-holder heads particularly used on machines for working wood or similar material.
  • rotating heads on which suitable knives are attached and which, mounted on the relative machine tools, are used for profiling elements of wood or similar material.
  • these rotating heads generally consist of cylindrical bodies provided on their periphery with longitudinal grooves suitably shaped and equipped with means for fixing special plates of appropriate metal, constituting the knives of the resulting tool.
  • the knives normally used can be constituted by a single-body element, clamped in the respective groove by a jaw pushed by screws conveniently placed. Normally, these knives are fixed in a single position, which makes any resharpening operations considerably difficult.
  • Knits similar to the previous type, consist of two elements brazed together, and precisely, a first carbide plate constituting the knife itself and a second steel plate forming the support element on which is fixed the previous brochure. Even this solution has the disadvantages of the previous one.
  • a subsequent solution provides for the use of a support element which is provided on one face with a plurality of slight longitudinal incisions capable of engaging on the corresponding incisions located on the face of the groove, against which it is tightened. .
  • the plate forming the knife element can result in such a way brazed on the above support element or also separate.
  • the object of the present invention is to compensate for the above-mentioned drawbacks, and for others which are very well known, obtaining, simultaneously, a very rational arrangement which guarantees the maximum reliability of use, making it possible, moreover, to very easily carry out resharpening. , both on the back and on the front of the knife, and, moreover, to be able to vary in a wide range of re-use, the shape of the profile of the knife.
  • the aforesaid support plate is provided with at least one projecting part, capable of engaging in the corresponding grooved part located on the aforementioned knife.
  • a further characteristic consists in the fact that the aforesaid projecting part, being on the aforesaid support plate, is constituted by at least one raised longitudinal edge and the aforementioned grooved part, being on the aforesaid knife, is constituted by at least one corresponding groove, in which the aforesaid raised longitudinal edge results being able to engage.
  • Another achievable form of the aforesaid reciprocal fixing means consists of at least one stud projecting from the said support plate and which can engage in a corresponding hole located in the aforementioned knife.
  • FIG. 1 we can observe the rotating head 1 in which the longitudinal grooves 2 are located, capable of containing the knife and the relative clamping group.
  • the external angle of the abovementioned face 21, will result provided with a chamfer 211, moreover, on the abovementioned anterior face 21 there are suitable threaded holes 12 in which are screwed the respective pressure screws 12.
  • the aforesaid rear face 22 results provided with a plurality of slight longitudinal grooves 221, which, as can be seen in FIG. 1, have a triangular section and are located side by side so as to completely cover the surface of the said posterior face 22.
  • a group of elements consisting of a knife 3 , a support 4 and a clamping jaw 5.
  • the above knife 3, as can be seen in FIG. 2 is constituted, as is known, by a plate 31 constructed of suitable metal. Initially, this plate 31 has a parallelepiped shape, and the side forming the back 32 is conveniently shaped in a notorious manner to obtain the desired profile. Near the opposite side, on the side which will result adjacent to the support 4 during mounting, there is a longitudinal groove 33 parallel to the same side.
  • the support 4 as can be seen in FIG. 2, is basically constituted by a steel plate 41, at the lower end of which there is a protruding rim 42, having the shape "L".
  • the aforesaid clamping jaw 5 is conspicuously constituted by a metal bar 51, fundamentally parallelepiped, the upper edge of which will eventually result, if appropriate, with the curved part 52, connecting to the element 211 and which, in addition, provided with a suitable groove 53 in which the heads of the pressure screws 13 can engage in abutment.
  • the knife 3 is applied to the relative support 4 and everything is introduced into the relative longitudinal cavity 2, into which the clamping jaw 5 is then also introduced, and the control screws 13 are screwed which will be in contact with the surface of the groove 53; in this way, the entire group consisting of the support 4, the knife 3 and the clamping jaw 5, will be clamped between the surface of the rear face 22 and the heads of the control screws 13.
  • the control screws 13 are screwed which will be in contact with the surface of the groove 53; in this way, the entire group consisting of the support 4, the knife 3 and the clamping jaw 5, will be clamped between the surface of the rear face 22 and the heads of the control screws 13.
  • the projecting rim 42 of the support 4 has a thickness slightly less than the thickness of the plate 31, which constitutes the above-mentioned knife 3; in this way, when the control screws 13 are fully screwed, the thrust of the clamping jaw 5 develops completely only against the aforementioned knife 3 which thus surely results clamped between the said jaw 5 and the aforesaid support 4.
  • the flange protruding longitudinal 44 will presently have dimensions slightly smaller than those of the relative longitudinal groove 33 of the above knife 3, so that the tightening can cause perfect adhesion of the opposite surfaces of the knife 3 and relative support 4, in addition, the position of the knife 3 will result defined by the only pressing of the lower edge against the upper surface of the protruding edge 42 of the support 4.
  • the two elements, knife 3 and relative support 4 are profiled separately with appropriate tools and consequently the successive profiling or sharpening of the back can be carried out directly with the group mounted on the respective head. It is even possible to sharpen the knife 3 on its front.
  • the mechanical tightening of the knife 3 also allows a better yield of the hard metal plate constituting the same, compared to the soldering.
  • the plates 31 constituting the knife 3 and the relative supports 4 can be amply recycled. More precisely, these elements, after having been used with a first profile, can be reprofiled with other profiles compatible with the remaining dimensions.
