Definitions

  • the invention relates to a belt grinder, especially for machining cylindrical Workpieces, with an endless sanding belt that passes around Rolls runs attached to a bracket and are aligned parallel to each other, whereby a roller is provided with a drive.
  • Belt grinders are used to process surfaces with an endless sanding belt that runs around in parallel aligned roles that runs are attached in a holder, which is usually from Housing of the grinder is formed or with communicates with him. At least one role is directly or through translation elements with a Drive connected by which they rotate is relocatable. As a result, this also becomes flexible Material existing sanding belt moves that on the outside, i.e. on the side facing away from the rollers Surface, with abrasive or other Abrasives is occupied. By putting on the moving Sanding belt, which for this purpose has a Outside of the grinder is guided to a Workpieces can thus be processed. Depending on the occupancy of the sanding belt for example, the processing consists of one Grinding, polishing or satinizing.
  • this object is achieved by that the holder has an indentation is open at the end and in which the to be processed Workpieces can be inserted radially, two Rolls on opposite edges of the indentation are arranged, a third role in the crown the indentation is arranged, a run of the Sanding belt runs through the indentation and the length of the sanding belt is greater than the common Circumferential length of the rolls is.
  • the proposed grinder is characterized by a holder for his roles with a Indentation is provided.
  • the dimensions of the indentation are chosen such that the ones to be processed Workpieces in total or with an axial Section and with its full cross section or at least radially into it at the edge let it slide in.
  • the insertion takes place in such a way that the axis of the workpiece is parallel to the axis the roles are aligned.
  • this becomes the holder with the indentation on the workpieces postponed. End face, d. H. in the direction the roller axes, the indentation is open. Consequently it can also be pushed onto such workpieces, whose length is greater than the diameter of the Belt grinder in the direction of the roller axes is.
  • the indentation an approximately cylindrical, profile-like shape has a semicircular cross-section.
  • rollers for guiding the sanding belt on opposite edges of the indentation arranged, preferably in the area of the edges, which limit the indentation.
  • a third Roll around which the sanding belt also runs, is outside or at the edge of the indentation on the Attached bracket and is in a parallel plane aligned to the roller axes between the first two roles. So that is third role in the area of the apex of the indentation arranged. It is conceivable in the area of Crest instead of a single roll two or to provide several roles over which the sanding belt is led.
  • a run of the sanding belt runs through the indentation, where appropriate, an opening in the Bracket or in the housing of the belt sander is available for implementation.
  • the length of the Sanding belt is larger than the common circumferential length the roles over which it is conducted. Consequently it lies loosely in the unloaded state Rolls on or is spaced from them.
  • the belt sander is used in the Way that the bracket with the indentation about the workpiece to be machined is pushed.
  • the run of the sanding belt through the indentation thus lies on the surface of the workpiece, the sanding belt by the abutment is stretched over the rollers.
  • the maximum length the sanding belt is therefore so small that it is clamped before or when the workpiece
  • the apex of the indentation touches.
  • a frictional contact with the roles so that the grinding belt from the driven roller in Movement is offset and the processing of the Workpiece surface takes place.
  • the diameter the indentation and its opening angle preferably chosen so that the workpieces are inserted leave and at the same time as small as possible Distance between the rollers at the edges the indentation is present, whereby an advantageous, maximum contact area of the belt on Workpiece is created.
  • the speed of movement the volume should be adjusted so that the The surface of the workpiece is not excessively heated and possibly tarnishing or excessive tape wears out quickly.
  • the advantage of the belt sander according to the invention is that it is a quick and even Machining surfaces cylindrical and rotationally symmetrical workpieces, such as pipes, enables. This eliminates the need in particular an elaborate and lengthy manual Editing. It proves to be a special advantage yourself that the grinder is in the radial direction the workpieces are put on. So the editing also possible if the workpieces are on both ends with other elements or parts of buildings are connected. For example, with the belt sander bars of banisters Machined from stainless steel, which after assembly are to be satinized or polished.
  • the bracket in the plane perpendicular to the roller axis an approximately U or V shape. Consequently creates a fork-shaped bracket with two Thighs, if necessary, through a central area are connected.
  • the roles are arranged expediently at the free ends of the legs and in the apex or middle area between the Thighs.
  • the significant advantage of a fork-shaped Bracket is comparatively small Diameter of their legs, so that the belt sander even in confined spaces, for example, a short distance away a wall or between adjacent workpieces can be used without problems.
  • the indentation in terms of their parallel to the roller axes running center plane asymmetrically shaped is.
  • legs on opposite Different sides of the indentation Have lengths or diameters. This too Working in confined spaces make things much easier, especially if a leg to be guided around the workpiece narrower and shorter than that part of the bracket is formed, the opposite Edge of the indentation and e.g. the drive records.
  • the cover can e.g. from the bracket are formed or attached to it be. It is both a closed as well an apertured cover, such as a Grid, functional. Furthermore, the cover form a guide of the grinding belt, for example by placing it in the edge of a groove or between Elevations engages on the inside surface of the cover. In this way it is sufficient Guide the sanding belt in place if there is does not rest on a workpiece and loosely over the Rolling runs. The roles are also avoided of injury risks, preferably on the front blinded by a cover.
  • the drive is releasably attached to the driven roller, for example by means of a clutch.
  • the drive units of others are particularly suitable artisanal devices, for example a One-hand angle grinder, on which the holder of the Belt grinder attached instead of a cutting disc becomes.
  • the advantage here is that the Angle grinders not only to drive the belt grinder, but also as its handling unit serves.
  • the bracket is useful therefore with fastening devices on the edge provided, for example, a handle for handling or have the drive fastened.
  • the rollers of the grinding device preferably exist made of rubber or another rubber-elastic material or are at least on the outside with such Material occupied. Because of the elasticity the rolls are created when the belt is tensioned good frictional connection, especially at the driven role is important. In addition due to the frictional connection, the guide to the Improved roles. Finally, the mechanical diminishes Compliance of the roller surface Strain on the belt and thus avoids it premature wear.
  • the distance between the rollers especially the two opposite edges of the indentation, there are two different requirements.
  • the distance is short Roll the advantage that the contact surface of the Grinding belt on the surface of the workpiece enlarged and thus the advantageously machined area increased. Therefore, it is advantageous Proposed embodiment of the invention that the distance of the rollers and if necessary the distance between opposite sides of the indentation is changeable.
  • the rollers can be moved in the holder to fix.
  • the apex angle between opposite Legs of the indentation and thus the distance between the rollers attached in them mutual pivoting of the legs changeable is. Allow locking or locking devices fixing the roles in predetermined positions.
  • the proposed grinder includes in his basic structure three roles (1 - 3), which in an approximately U-shaped or crescent-shaped bracket (4) attached and are guided over a grinding belt (5) is, the outside (6) with an abrasive coating is provided.
  • the grinding belt (5) is there with a strand through the indentation (7) of the bracket (4) guided and exceeds in length common circumference of the rollers (1 - 3), so that loosely attached to them in the unloaded state fits or runs freely around them.
  • a workpiece (8) for example a Tube, inserted into the indentation (7) or Bracket (4) with the indentation (7) on the workpiece (8) put on.
  • it will Tension the sanding belt (5) over the rollers (1 - 3) and lies with the outside (6) on the Surface of the workpiece (8).
  • the role (1) the in connection with a drive, not shown stands and in its diameter the other roles (2, 3) exceeds, that moves to their surface pressed grinding belt (5) in motion, so that the Machined workpiece surface through its coating becomes.
  • Drive and handling devices for example a handle that can be attached to an edge Fastening element (9) of the holder (4) attach.
  • the arrangement of the rollers (1, 2) that make up the sanding belt (5) over the workpiece (8) takes place opposite edges (10, 11) of the indentation (7), preferably in the area of their edge Edge. In contrast, it is only for redirection serving role (3) in the apex area of the indentation (7) located.
  • the indentation is preferred (7) asymmetrical with respect to their central plane (12) trained, d. H. the legs (13, 14) of the Bracket (4) point on opposite sides the middle plane (12) different lengths and Diameter on.
  • the result is a belt sander, that is the quick, simple and even Machining of cylinders and rotating bodies allowed and even with end-side attachment the workpieces can be used.
