Definitions

  • Machining devices for the machining of metallic workpieces such as, for example, satinizing, grinding or deburring machines are known.
  • circumferential machining materials such as friction or abrasive belts are used, which drive past areas to be machined on the workpiece, wherein a working side of the belt is moved in the direction of the workpiece (see, eg NL-A-8801575 ).
  • pressure mechanisms have been realized for processing belts, which are not yet completely satisfactory.
  • Object of the present invention is to improve a device of the type mentioned in terms of technical and economic aspects, in particular with regard to a roughing or roughing of profiled metallic workpieces with comparatively strong burr formation or significant material supernatants.
  • the invention is initially based on a device for processing a strip-shaped or plate-shaped metal workpiece, in particular for deburring cutting edges and / or grinding surfaces of the workpiece, with at least one processing unit, with which a driven rotating processing belt obliquely or transversely to a Feed direction of the workpiece in a working range of the processing belt at least approximately linearly past the workpiece and thereby the workpiece is machinable on a working side of the processing belt, acting on a movable support member pressing means act on a back of the processing belt to a necessary for editing contact between the working side of the machining belt and the workpiece to influence.
  • the workpiece is e.g. on a conveyor table resting on the work area of the processing belt or relative to this moved past.
  • the conveyor table may in particular comprise a driven conveyor belt or driven conveyor rollers.
  • the working side of the closed processing belt is formed on the outside and facing the contacting of the workpiece this.
  • the work page is designed for material removal, e.g. equipped with a variety of tool-like processing elements or provided with a rough hard material surface or a grain, in the manner such as a sandpaper abrasive belt.
  • the core of the invention can be seen in the fact that a drive arrangement is provided, with which the carrier element can be driven by a motor, so that the carrier element moves with the pressure means at least in the working area of the processing belt substantially parallel to the direction of movement of the processing belt.
  • pressing means are positioned almost immovable or positionally pressing against the processing belt.
  • the pressing means may yield slightly perpendicular to the direction of movement or to the running direction of the processing belt.
  • the carrier element can be driven by the pressing means, in particular independently of the revolving processing belt, for example, via its own drive.
  • a movement with or without reversal of motion for example, back and forth or continuously moving in one direction is possible.
  • a separate or only the movement of the carrier element serving drive is present.
  • a direct or direct drive or an indirect drive of the carrier element can be set up.
  • a common drive unit for the processing belt and the carrier element, which is advantageous It is also possible for a common drive unit to be present, with the processing belt and the carrier element being able to be brought to other drive speeds via corresponding gears or over or under gear reduction.
  • the carrier element is designed as a revolving endless element, on which the pressing means are provided such that the pressing means press on the back of the processing belt in a gap.
  • the pressing means are provided such that the pressing means press on the back of the processing belt in a gap.
  • the work area in which the processing belt can come into contact with the workpiece for example, above the conveyor table and thus defines a maximum
  • simultaneously contacted by the pressing means surface of the back of the processing belt according to the invention is acted only on a part by the pressing means. In between the back of the processing tape remains free.
  • the partial application of pressure or force or the contact pressure on fractions of the entire area under consideration in the working area of the rear side of the processing belt therefore leaves gaps between adjacent contact areas on the rear side of the processing belt contactless.
  • the interrupted by the pressing means gap on the back of the processing belt is present on both sides of an applied pressure surface and extends to the next pressing surface or to the end of the work area.
  • the processing belt in the two end regions of the working region is deflected upwards or downwards into the working area or away from it via deflection rollers or the like.
  • the drive for the endless element can be dimensioned smaller or more cost-effective.
  • the endless element may in particular be band, chain and / or string-shaped. Preference is given to a band which, in the working area, is oriented at least approximately parallel to the processing belt and at a predeterminable distance from it.
  • the circulating endless element can be designed in its nature and / or its dimensions matched to the desired pressing action.
  • the endless element has a width dimension, ie transverse to the direction of rotation, which corresponds to the width of the processing belt.
  • an element which, in another way, brings about a movement of the pressure means substantially parallel to the direction of movement of the processing belt.
  • the element may, for example, be slidably mounted in a plane or designed in the manner of a vibrating plate, e.g. driven by an eccentric and moved back and forth.
  • a support arrangement acting in the working area of the processing belt is provided.
  • the support arrangement thus acts in the manner of an abutment in the region in which the endless element acts on the back of the processing belt via the pressing means.
  • the support arrangement is in particular there to be able to apply the necessary force with the pressing means or to prevent an evasion or bending of the endless element upwards or to allow only a predetermined amount. Furthermore, any deflections that may occur in the direction of the support arrangement and thus vibrations of the endless element in the working area can be greatly minimized, especially at higher rotational speeds.
  • the support arrangement comprises a contact section for the support of the endless element such that the endless element can be reset in a direction away from the workpiece away.
  • unevenness or depressions and elevations on the workpiece can be achieved by the processing element.
  • a start setting whereby is achieved by adjusting the position of the endless element together with pressing means in relation to the processing belt, depending on the thickness or height of the workpiece, a pressing action by the pressing means.
  • the endless element with the pressure-exerting means can slightly recede from the workpiece by means of elevations on the workpiece and return to the basic position again when no elevation is effective.
  • the maximum possible deflection path for the endless element can be adjustable in particular via the predeterminable movement path of the contact section.
  • the contact section which is acted upon by a spring force, preferably supports the rear side of the endless element.
  • the endless element with the pressure means act on the processing belt, so that the working side of the processing belt presses against the workpiece with a sufficiently high force.
  • the working side of the machining belt can thus reach any protruding or deeper areas on the workpiece at any time.
  • the abutment section for supporting the endless element comprises a plurality of support elements which are juxtaposed in the direction of the longitudinal extension of the endless element and which are movable relative to a positionally fixed part via prestressed spring means.
  • the strength or possibly the characteristic of the evasive movement if, for example, different support elements are sprung to different degrees, does not have to be uniform or uniform over the entire working area.
  • the support can be segmented subdivided, resulting in different sections of the work area makes different evasive movements of the endless element or the processing belt possible.
  • a support element can be sprung parallel to the rear side of the endless element or angularly movable.
  • the support can also be correspondingly adapted to this angling or inclination, even in the case of an adjustment of the processing belt which is angled relative to the initial orientation of the processing belt, and thus possibly of the endless element.
  • a greater surface finish is achieved.
  • the spring force of the spring means is chosen to be lower, depressions and elevations or edge portions on the workpiece can be processed better.
  • the contact section is preferably flat over a width at a rear side of the endless element.
  • the pressing means comprise a front of the endless element facing the processing belt at least one releasably attached pressure element.
  • the pressing means comprise a base part on which there is at least one pressing element which presses against the rear side of the processing belt.
  • the pressing element comprises elastically yielding sections which, in the state of pressing against the rear side of the machining strip, allow an elastic yielding of the pressing element.
  • the elastic portions may lie in particular in the interior of the pressure element.
  • the processing of profiled sections on the workpiece can thus be done even better.
  • the pressure element can be equipped with a friction-resistant material on its front side, which comes into contact with the rear side of the processing belt, so that the longevity of the pressure element or of the processing belt is advantageously increased.
  • the drive arrangement is designed to drive the endless element and the processing belt in the same direction of movement at different speeds.
  • the speed of the endless element is slightly less than the speed of the processing belt.
  • the endless element is designed to remove and / or replace at least individual pressure elements arranged on the endless element in the installed state of the endless element.
  • the number and / or configuration of the pressing elements arranged on the endless element can therefore be made particularly variable. With a higher number of pressing elements, the processing intensity can be increased.
  • the endless element is designed in such a way to attach thereto differently shaped pressing elements.
  • the endless element can in particular be variably equipped with pressure elements, for example, depending on the type of workpieces to be processed.
  • the pressure element is releasably attached via a sliding fit on the endless element.
  • a sliding seat allows a particularly simple removal or attachment of the pressing element. Another advantage is that an exchange of a pressure element by a handle or without tools is possible.
  • the invention is also directed to a processing station for processing a strip or plate-shaped metallic workpiece, which has a finishing unit with a finishing belt for processing the workpiece, according to the invention there is a device upstream of the finishing unit, which is designed according to one of the above-mentioned devices.
  • the basic idea of this arrangement is that e.g. a smaller, slightly driven sanding belt is positioned in front of a lamellar sanding belt, with only partially pressed areas by the pressing elements, which can change in their position to the workpiece. This allows workpieces in a unit initially free of coarse burrs and the like, before the finishing can be done effectively by the finishing. Without the upstream processing device, a desired high processing quality, in particular of workpieces with strong burrs or material projections, could not be achieved in one unit.
  • FIG. 1 is a front view of a part of a processing station with a processing device 1 according to the invention with a machine body 2 and a processing belt 3 shown.
  • the processing station is designed in particular as a machine unit.

  • the processing belt 3 is configured as an abrasive belt and has a correspondingly designed working side 3a, for example, with a sand grain.
  • the machining belt 3 can be driven with its rear side 3b via two rotating drums 5, wherein one of the two drums 5 is rotationally driven via a drive, not shown, in particular with an electric motor.
  • the processing belt 3 is driven circumferentially, for example, in the direction of the arrow P1 or counterclockwise and linearly transversely or obliquely past the workpiece W.

  • the support belt 7 has a plurality of uniformly spaced Andschreib legin 8, each having the same length dimension 1.
  • the intermediate space with a length dimension L that is thus present between adjacent pressure shoes 8 is advantageously about three times as large as the longitudinal dimension 1 of a pressure shoe 8.
  • other aspect ratios L to 1 or lengths 1 and L may also be advantageous be. It is also conceivable that on an endless element not all pressure shoes 8 or intermediate spaces have the same length 1 or L, but e.g. are all different or coincide alternately.
  • FIG. 1 illustrates, it is also advantageously possible, instead of a total surface pressure surface on the back 3b of the processing belt 3 to set up a partial or gap-pressing surface.
  • the workpiece W can readily be further processed immediately, for example, by a person by hand without Protective measures such as gloves are taken.
  • a cooling phase can be omitted as a rule.
  • the endless element 6 can be driven (not shown) due to the low surface pressure by means of Andschreibzan 8 on the back 3b of the processing belt 3, for example, a relatively low-power drive motor, which drives a drive roller 9, by which the endless element 6 is guided.
