Definitions

  • the invention relates to a device for machining e.g. workpieces made of wood, preferably by means of a rotating one Tool, especially thickness or planer-thicknessing machine, with one Support for the workpiece and at least one spring-loaded pressure element, that, for example, as a roller or stamp and the edition arranged opposite one another and is movably supported against the support.
  • a device for machining e.g. workpieces made of wood, preferably by means of a rotating one Tool, especially thickness or planer-thicknessing machine, with one Support for the workpiece and at least one spring-loaded pressure element, that, for example, as a roller or stamp and the edition arranged opposite one another and is movably supported against the support.
  • At Devices of this type such as are known from EP-A2-373859, are designed as pivoting stamp pressure elements, but also as Pressing elements designed to be translationally movable are known, of which seen in the direction of movement of the workpiece, one stamp and one roll in front of the rotating tool (designed
  • each contact element Spring that strives to keep the pressure element in contact with the workpiece.
  • thickness planers or Surface planers clearly visible steps in the workpiece surface, which as Entry and exit stages are known. The reason for the occurrence of these stages is the elastic cushioning of the workpiece support when inserting the pull-out side Pressure roller and the elastic spring back when draining from the feed side Pressure roller.
  • the object of the invention is to avoid this disadvantage or at least to reduce.
  • the total spring characteristic of the load springs Pressure element is degressive.
  • Design of the device is achieved by a gentle application of force (or removal of force) onto the workpiece by the pressure rollers and outlet level are not changed in their dimensions, but a gentle one Transition is achieved on the surface of the workpiece, so that the input and Outlet stage no longer optically (or at least only in a significantly reduced amount Dimensions).
  • this gentle increase or decrease in power reached to or from the workpiece by the degressive spring characteristic preferably without prestressing the compression (or tension springs) can be.
  • Another embodiment of the subject matter of the invention stands out characterized in that the two springs with different characteristics opposite points of a bearing body for the as a pressure roller trained pressure element are supported, which bearing body slidably in the device is guided.
  • 4 is a workpiece made of wood. This workpiece rests on a support 5 designed as a table.
  • the edition 5 can also be formed by rollers or rollers or by a transport chain or a conveyor belt.
  • the workpiece is moved in the direction of arrow P advanced and by a rotating tool in the direction of arrow Q 3 processed.
  • the tool 3 is a knife shaft trained, which is equipped with two knives 6, the cutting diametrically are arranged opposite one another.
  • the pressure element designated 2 which is also called a roller is formed and arranged on the pull-out side.
  • Pressing element 1 is dashed out when it is placed on the workpiece 4 registered) rest position increased by an amount that is the sum of Depth of cut s and reserve stroke t.
  • pressing element 2 arranged on the pull-out side is just as far away from the support 5 is like the pressure element 1 arranged on the feed side, the pressure element 2 when placed on the machined surface of the workpiece 4 by the size of the Reserve stroke t raised.
  • the dimensions u and v of the pull-in side and the pull-out side Levels can be seen as they arise when machining the workpiece 4 set conventional planing machines.
  • the flight circle of the knife 6 of the rotating tool 3 is designated by 10 in FIG.
  • Cause of the occurrence of these stages is the elastic cushioning of the support 5 for the workpiece 4 when Insert the contact element 2 on the pull-out side and the elastic one Spring back when the pressure element 1 arranged on the feed side runs off.
  • the pressure elements 1, 2 are under spring pressure F.
  • the total spring characteristic for each contact element 1 or 2 is designed to be degressive, as shown in FIG. 4 in a diagram in which Abscissa the spring force F and as the ordinate the path f of the pressure element from the The rest position is entered away, the dimension u or v of the pull-out level not changed, but a smooth transition to the surface of the workpiece 4 achieved, as shown in FIG. 5. This smooth transition lifts up optically hardly anymore from the remaining, machined top of the workpiece 4.
  • the pressure element 1 or 2 which is designed as a roller, is rotatable mounted in a bearing body 11 which is displaceable in a guide 12 fixed to the frame is stored. From above acts on the bearing body 11 as a compression spring with a flat one Characteristic formed spring 7 and from below also as a compression spring, however with spring 8 which is steeper than spring 7. With F is that of the displacement f of the bearing body 11 or of the pressing element 1 or 2 dependent force designated by the pressure element 1 or 2 on the workpiece 4 is exercised. It can be seen (Fig.
  • both or just one of the Pressure elements 1, 2 can also be designed as a stamp on the surface of the Workpiece 4 comes to rest.
  • the stamp must then have an inclined contact surface for the workpiece 4, so that the front edge of the workpiece 4 at Run up to the stamp, raise it.
  • the pressure elements 1, 2 can also be pivotally mounted in the device so that the springs 7 a moment exert the pressure elements, under whose influence the pressure elements then with the Force F rest on the surface of workpiece 4.
