Definitions
- the present invention relates to a cutting sonotrode for an ultrasonic cutting machine according to the preamble of claim 1.
- Ultrasonic cutting machines for cutting textiles, fabrics, non-wovens, Films, rubber composites, foods, etc. have long been known. They usually have a fixed vibrating unit included the cutting sonotrode and a fixed or rotating counter bearing. For the cutting / separating effect are generated by the vibrating unit high-frequency ultrasonic vibrations used.
- the object of the present invention is a cutting sonotrode for an ultrasonic cutting machine of the type specified, that expands their uses while maintaining the danger from contamination of the cutting edge when cutting highly viscous media becomes. Furthermore, an amplitude maximum of the vibrations at the Cutting edge of the sonotrode body and thereby the best possible efficiency for the introduction of energy into the material to be cut.
- the sonotrode body has such a shape that it is axial entered longitudinal vibrations essentially by 90 ° in an annular Deflected cutting edge.
- the sonotrode body is also around its axis of symmetry can be rotated around the ring-shaped cutting edge for cutting the material to rotate.
- the rotary movement of the cutting edge and the optimal amplitude at the Cutting edges prevent a build-up of what is to be cut which is harmful to production Material in front of and on the cutting edge.
- the cutting sonotrode designed according to the invention is therefore particularly suitable for continuous cutting processes highly viscous and thermoplastic media.
- the cutting sonotrode designed according to the invention is Can be used in all applications that were previously with mechanical rotating knives be carried out, at most metallic and other hard materials with exception of.
- the shape of the sonotrode by which the longitudinal vibrations are redirected depends on the application and can, for example can be determined by finite element calculation methods.
- the sonotrode body has one cylindrical section, a conical section adjoining this and a flange-like adjoining this, provided with the cutting edge Section.
- the cutting edge is here from the radially outer end of a thin one Washer formed from the flange-like portion of the sonotrode body extends radially outward.
- the sonotrode body is expedient further provided with a central recess, which consists of a cylindrical and an adjoining conical section.
- the cutting sonotrode 2 shown schematically in FIG. 1 is used for cutting of material 4, which is supported by a rigidly arranged counter bearing 6.
- the counter bearing 6 can, however, also be arranged to be movable (rotating), such as this is indicated in Fig. 2.
- the cutting sonotrode of FIG. 2 is otherwise identical with the cutting sonotrode of FIG. 1.
- the material 4 to be cut can be a highly viscous one and thermoplastic medium. However, you can use any other Materials are processed provided their hardness and other properties allow this.
- the cutting sonotrode 2 has a sonotrode body 8 which is rotationally symmetrical about an axis A.
- the sonotrode body 2 has at one end a planar input surface 10 which can be connected to a booster (not shown) or possibly directly to a converter (not shown) in order to be subjected to longitudinal vibrations in the axial direction, as indicated by the double arrow L E is indicated.
- the sonotrode body 8 is provided with an annular cutting edge 12, which serves as the starting surface for the vibrations causing the cutting effect.
- the sonotrode body 8 has such a shape that it deflects the axially input longitudinal vibrations (arrow L E ) by 90 ° so that they are available in the form of radially directed longitudinal vibrations on the annular cutting edge 12 for cutting the material, as is the case is indicated by the double arrows L A.
- the shape of the sonotrode body 8 that is suitable for this depends on the specific application and can be determined electronically, for example, by finite element calculation methods.
- the sonotrode body 8 can be driven to rotate about its axis A.
- any drive (not shown) can be used.
- the on this Annular cutting edge 12 set in rotation can thus be continuous Cutting / separating processes on the material supported by the counter bearing 6 4 perform.
- the rotational movement of the cutting edge 12 and the amplitude of the longitudinal Vibrations of the cutting edge 12 ensure a relatively low friction between the material 4 and the side surfaces of the cutting edge 12.
- the sonotrode body 8 can be mounted so that its axis A is stationary is. Instead, it can also be stored so that the ring-shaped Cutting edge 12 for making profile cuts at variable angles can be employed for the material 4 to be cut.
- the sonotrode body 8 can be attached to a robot arm (not shown), so that it can be spatially adjusted to cut out bodies and surfaces is. This results in the advantage of a free cutting geometry.
- FIG. 3 An embodiment of a sonotrode body designed according to the invention 8 is in Figs. 3 and 4 shown in more detail in an axial longitudinal section.
- the sonotrode body 8 has a cylindrical Section 14, one axial end face of which forms the input face 10.
- the cylindrical Section 14 is provided with a threaded bore 15 around the sonotrode body 8 by a screw connection with the booster (not shown) or to connect the converter (not shown).
- a conically widening section 8 which by means of a radius in a radially outward, cylindrical, flange-like section 18 passes.
- flange-like section 18 has a flat end face 20. Adjacent to the flat end face 20 extends from the flange-like section 18 a thin washer 22 radially outward, the radially outer end forms the annular cutting edge 12.
- the cutting edge 12 has in the illustrated Longitudinal section of the sonotrode body 8 in the form of a needle tip, the of the included angle ⁇ on both sides of the needle tip, for example in the Of the order of 10 °. It is understood that the cutting edge also others Can have shapes.
- the sonotrode body 8 is also provided with a central recess 24, which consists of a cylindrical section 24a and a conical section 24b composed.
- the cylindrical section 24a of the recess 24 borders on the one hand on the flat end face 20 and on the other hand goes into the conical Section 24b, which ends in a closed rounding.
