Definitions
- the invention relates to an abrasive formed in Form of a strip of abrasive cloth, for Equipping the work surface of a rotating machine grinding tool.
- Rotating machine grinding tools with those in the industrial scale, especially in the furniture industry, is ground can be divided into genres all-round grinding belts and rotating grinding wheels or Rollers.
- the system with the workpiece to be ground bring work surfaces of the grinding tools with abrasive abrasive.
- abrasives consist of a base of paper, tissue or the like, one surface of which is made of a layer abrasive grains.
- abrasive cloth glued to the work surfaces, the to be renewed regularly due to relatively short downtimes is by loosening the glue and then new abrasive cloth is stuck on.
- the working surfaces are for grinding profiles Grinding tools contoured accordingly.
- the glued on Abrasive cloth is sufficiently thin to fit the contours to be nestled. It has been shown that the Profile grinding Point supports of the abrasive on the abrasive profile can result in undesirable "Chatter marks" in the surface of the surface to be ground Workpiece occur. In addition, the point support under Local circumstances lead to such high pressure that occurring Frictional heat leads to "burning" of the abrasive. About that In addition, an intermediate sanding with abrasive cloth is not possible because the paint layer is sanded through.
- FR-A-2 622 136 it is known to be the working surface of a rotating cylindrical grinding tool with glued on To pad and onto the peripheral surface of the Upholstery to stick a sandpaper.
- the invention is based, an abrasive for a task revolving To create machine grinding tool where the Disadvantages described above do not occur.
- a suitable foam can therefore be used for the upholstery appropriate porosity and elasticity can be selected.
- a grinding tool for example a rotating one Grinding wheel, can be in preparation for the grinding process his work surface with a foam pad be occupied. Then an abrasive cloth is placed over it placed the free surface of the foam pad covers.
- the pad can be glued to the work surface, whereby the Abrasive cloth in turn can be glued to the upholstery. In this way you can easily contoured Working surfaces of grinding tools for profile grinding equip.
- the abrasive according to the invention can be relative be ground aggressively, due to the Lining the abrasive cloth with an elastic Upholstery whose disadvantages do not occur.
- grinding with "chatter marks" occur in the abrasive according to the invention not on and the abrasive cannot burn; because no frictional heat builds up because of the Grinding pressure is even.
- the abrasive is suitable therefore advantageous for grinding profiles, since a large abrasive pad on the workpiece is. Larger deviations in shape are advantageous and dimensional tolerances balanced.
- a suitable foam can therefore be used for the upholstery appropriate porosity and elasticity can be selected.
- the abrasive cloth and the upholstery are in the form of strips before that just cut to the appropriate length become.
- the abrasive cloth strip is particularly broader than the upholstery strip. This enables the longitudinal edges of the abrasive cloth strip over the longitudinal edges of the upholstery strip to pull and on the grinding tool, for example a rotating grinding wheel To fix glue.
- the cushion is therefore under the Abrasive cloth completely encapsulated and against mechanical Impacts protected.
- abrasive according to the invention with which a Equipping the grinding tool is a central strip area of the abrasive cloth strip with a cushion strip coated.
- a one-piece made of upholstery and abrasive cloth Abrasives are provided in strips or Band form is present. Can from the abrasive strip Cut sections of appropriate length with which equip the work surfaces of a grinding tool to let.
- At least one of the Notches on the longitudinal edges of the abrasive strip Preferably, both longitudinal edges of the Abrasive strip with corresponding notches provided that the abrasive strip is nestled in corresponding contours in the work surface of a Facilitate grinding tool.
- the notches are like this attached that they are at least partially in each protrude into the adjacent edge of the upholstery strip.
- the Pad strips on the underside of the loop it does not hinder those for nestling into the Contours of the work surface necessary deformations.
- the notches can be simple, more or less acute-angled incisions.
- the notches are preferred as parallel to the respective longitudinal edge of the abrasive extending hole row, being in each hole a longitudinal edge incision is made.
- the pad strip can be on the underside of the abrasive cloth strip with appropriate means, for example Adhesives.
- FIG. 1 is a schematic view of a grinding tool 1 shown in section.
- the grinding tool owns a tool body 2 with against no further here Workpiece shown can be pressed on the work surface 3.
- the Work surface 3 is with a cushion 4 made of foam busy.
- Abrasive cloth 5 is placed over the upholstery is wider than the cushion 4, so that its longitudinal edges 6 and 7 can be folded down over the side edges of the cushion 4 are draggable and on the flank surfaces 8 and 9 of the Tool body 2, for example by gluing, attachable are.
- the cushion 4 is protected under the against mechanical loads of relatively resistant grinding lines 5.
- the cushion 4 can also be placed on the work surface 3 can be glued. Furthermore, it is possible that Abrasive cloth with the top of the pad facing 4 to glue all over.
- Fig. 2 shows a bottom view of an abrasive used in Form of a strip is prefabricated, of which one here Section is shown.
- the abrasive consists of the Abrasive cloth strip 5, the central strip area with a Strip of upholstery 4 is coated. Because the abrasive cloth strip 5 is wider than the upholstery strip 4 only the protruding longitudinal edges 6 and 7 are visible here, the longitudinal edges of the cushion strip 4 designated 10 and 11 are.
- Fig. 3 shows a sectional view of the abrasive along the line III - III in Fig. 2. Under the abrasive cloth strips 5 the pad 4 is glued. The longitudinal edges of the Abrasive cloth strips 5 are again designated 6 and 7, it is clearly visible here that the abrasive cloth 5 is wider than the cushion 4. Same as in Fig. 2, too visible in Fig. 3 that the trained as a row of holes Notches are partially in the upholstery strips 4 stretch in.
