Definitions

  • the present invention relates to a grinding device with a grinding belt mounted on a drivable, flexible substrate body.
  • the consumption of grinding belt is relatively high because, on a substrate body that is not very elastic, the local wear of the relatively highly stretched grinding belt can be considerable and, on a highly elastic substrate body, the grinding belt stretched less tends to form waves and has to be replaced more often.
  • the known elastic substrate body is constructed on a rigid base body associated with expense, which base body can also be damaged during replacement of the grinding belt and then has to be replaced.
  • a roller for polishing surfaces of workpieces made of stone or stone-like materials with a metal core that can be accommodated on a drivable spindle and an outer layer containing a mineral polishing agent bound by a binding agent.
  • the metal core has a mantle comprising a rubber elastic material which holds the outer layer that comprises a granulate embedded in a matrix formed by an adhesive, which granulate contains a mineral polishing agent bound by a binding agent, whereby the adhesive is more elastic than the granulate in the solidified state.
  • the grinding granulate has to be introduced into the adhesive in a uniformly distributed manner during the production of the elastic outer layer comprising adhesive. This introduction often causes difficulties and depends on the consistency of the grinding granulate.
  • the rigid metal core prevents the formation of any elastic grinding tools.
  • Another surface machining device is known from DE-U1-29714279.
  • the provided substrate body to be replaced is a metallic piece that is associated with relatively high costs.
  • An elastic intermediate layer is applied to the substrate body, which layer carries the machining layer.
  • the disadvantage of this arrangement is that relatively high costs are incurred by the use of a metallic substrate body.
  • This metallic substrate body has to be present with every replacement tool, whether coarse or fine, soft or hard.
  • the present invention relates to a grinding device of the type mentioned at the outset which can be used with a relatively low-elastic substrate body as well as with a highly elastic substrate body and is economically advantageous.
  • the grinding belt with the flexible substrate body is embodied or formed in one piece and the flexible substrate body is directly attached to the drive in a detachable manner.
  • the grinding belt and the flexible substrate body are mutually held together firmly, such that the flexible substrate body is directly attached to the drive in a detachable manner.
  • the flexible substrate body is made of an elastomer.
  • Elastomers are, e.g., natural rubber, chlorinated rubber, polybutadiene, polyurethane, silicone rubber, etc.
  • the production of the flexible substrate body can be designed advantageously by a suitable choice of the elastomer.
  • the flexible substrate body made of an elastomer can thus be firmly connected directly to the back of the grinding belt and can even be hardened there.
  • the Shore hardness of the flexible substrate body is advantageously between 40 and 85 Shore. Grinding devices for machining all sorts of workpieces, such as stone, steel, aluminum, etc. can be created through the suitable choice of the Shore hardness.
  • the shape of the flexible substrate body can be adapted to the drive provided.
  • the flexible substrate body can thus be a laterally guided endless belt running on drive cylinders.
  • the flexible substrate body can also take over the lateral guiding of the endless belt.
  • the endless belt can thereby be provided on the back facing away from the grinding belt with at least one projecting endless guide piece.
  • the guide piece is guided in a groove of the drive cylinder, whereby a secure lateral guiding of the substrate body with the grinding belt is achieved.
  • the flexible substrate body can also be an elastic, cylindrical body.
  • the central bore of this body can advantageously be pushed onto a drive shaft in a rotationally locked manner. In this arrangement, replacing a worn grinding belt is particularly easy.
  • the present invention is directed to a grinding device including a grinding belt and a flexible substrate body.
  • the grinding belt is mounted on the flexible substrate body in one piece and the flexible substrate body is detachably attachable to a drive device.
  • the flexible substrate body can be composed of an elastomer. Further, the flexible substrate body may be firmly attached directly to a back of the grinding belt.
  • the flexible substrate body has a Shore hardness between 40 and 85 Shore.
  • the flexible substrate body can be a laterally guided endless belt.
  • the endless belt can be provided with at least one projecting endless guide piece, and the at least one projecting endless guide piece is arranged on a surface of the endless belt opposite the grinding belt.
  • the flexible substrate body may be an elastic cylindrical body.
  • the elastic cylindrical body can include a plurality of longitudinally extending groove corresponding to longitudinally extending ribs on the drive device.
  • the flexible substrate body can be directly attachable to the drive device.
  • the grinding belt can be mounted to the flexible substrate body by vulcanization.
  • the flexible substrate body can be an elastomer and the grinding belt can be mounted to the flexible substrate body before the elastomer has hardened.
  • the present invention is directed to a process of forming a grinding device.
  • the process includes mounting a grinding belt onto a flexible substrate body to form one piece.
  • the grinding belt can be mounted to the flexible substrate body by vulcanization.
  • the flexible substrate body can be an elastomer
  • the grinding belt can be mounted to the elastomer before it has hardened.
  • the process can further include detachably attaching the flexible substrate body to a drive device.
  • the flexible substrate body may be directly attached to the drive device.
  • the flexible substrate body can have longitudinal grooves on a surface opposite the grinding belt that correspond to longitudinal ribs on the drive device, and the process may also include sliding the longitudinal grooves of the flexible substrate body over the longitudinal ribs of the drive device.
  • the flexible substrate body has a Shore hardness between 40 and 85 Shore.
  • the present invention is directed to a grinding device that includes a one piece element composed of a grinding belt and a flexible substrate body structured to be detachably attachable to a drive device.
  • FIG. 1 illustrates a grinding device with an endless belt as a substrate body with grinding belt
  • FIG. 2 illustrates a cross section of an endless belt carrying a grinding belt with an endless guide piece on the back of the endless belt with drive cylinders
  • FIG. 3 illustrates a cylindrical substrate body with a cylindrical grinding belt.
  • FIG. 1 shows a grinding device with an endless belt 1 which is attached to two drive cylinders 2 and 3 .
  • Endless belt 1 comprises a flexible substrate body 4 and a grinding belt 5 connected to substrate body 4 in one piece. Grinding belt 5 and substrate body 4 lying beneath are mutually held together firmly.
  • Substrate body 4 is made of an elastomer that is firmly connected to the grinding belt 5 by vulcanization or by another suitable process. With one-piece carrier and grinder layers, the Shore hardness of substrate body 4 is determined by the workpiece to be ground. A soft substrate body 4 would be advantageous in order to be able to grind a thin sheet metal. A hard substrate body 4 would be desirable to grind a stone. In practical operation, a Shore hardness between 40 and 85 is chosen for substrate body 4 .
  • the endless belt shown in FIG. 1 is provided with a conventional lateral guide.
  • the lateral guide can be combined with substrate body 4 of endless belt 1 , as is shown in FIG. 2 .
  • Substrate body 4 is provided on its back facing away from grinding belt 5 with a projecting endless guide piece 6 .
  • Guide piece 6 is guided in a groove 7 of drive cylinder 2 and also promotes the adhesion between drive cylinder 2 and endless belt 1 .
  • FIG. 3 shows another embodiment variant of the described grinding device.
  • Flexible substrate body 8 is here a cylindrical body.
  • Grinding belt 9 is embodied or formed with substrate body 8 in one piece.
  • Substrate body 8 features a central bore 10 which is provided with longitudinal grooves 11 .
  • Substrate body 8 can be simply pushed onto a drive shaft provided with longitudinal ribs.
  • replacing substrate body 8 is particularly easy, i.e., it needs only to be removed from the drive shaft (not shown) and replaced with a replacement part.
