Definitions

  • the invention relates to a device for sawing with a saw table and a hand saw held on the saw table above the same, the hand saw being held in a guide so as to be longitudinally movable and vertically displaceable.
  • miter cutters which are U-shaped in cross section.
  • the base of this cutting drawer serves to receive the workpieces to be sawed, such as strips or the like, wherein clamping devices for clamping these objects to be sawn can also be arranged in the base.
  • the Legs of the cutting drawer have slots which are used to insert the saw blade, the slots on the one hand making an angular cut of 90 ° and on the other hand also making miter cuts of, for example, 45 ° and an oblique cut of 45 °.
  • miter saws are known in the prior art, in which a hand saw is held in a guide on a saw table, which is adjustable in its relative angular position to the saw table, either stepless or stepped, the guidance of the saw being lockable in any position.
  • Miter saws of this type can be used to provide miter cuts on strips or the like for sawing parts.
  • the invention has for its object to provide a device of the type described above, with which bevel cuts can be made in almost any angular position between vertical and horizontal.
  • the invention proposes that the guide about a horizontal axis is rotatably and lockably arranged, which axis is parallel to the longitudinal extension of the saw blade of the hand saw and is at least approximately in the plane of the saw table.
  • the guide of the hand saw is arranged rotatable and lockable about a horizontal axis, it is possible to arrange the guide between the vertical position and an almost horizontal position, so that the saw blade of the hand saw is either guided perpendicular to the workpiece located on the saw table or the saw blade can be aligned in a predetermined angular position deviating from this vertical position and the workpiece can be provided with a corresponding oblique saw cut.
  • the hand saw is held in the guide in a conventional manner in a longitudinally displaceable and vertically displaceable manner, as is known and customary, for example, in precision miter saws.
  • the guide consists of two coaxially opposite one another
  • Side surfaces of the saw table are arranged disks, which are each rotatably mounted in a half-shell-shaped body, the body having a substantially V-shaped cutout that opens to the hand saw and the disks have an engagement cutout for the saw blade of the hand saw, furthermore guide rods on the disks are attached for guide eyes of the hand saw, which extend at right angles to the longitudinal direction and parallel to the side surface of the saw blade.
  • this design creates a very simple constructive solution, on the other hand, a secure and permanent management is guaranteed even after a long period of operation.
  • the disks can be locked in different relative angular positions by means of a catch.
  • the disks are connected and positively coupled by means of a connecting part arranged below the saw table.
  • angle markings are arranged on the front surface of the one pane and a window is formed in the half-shell-shaped body, which exposes the angle markings in a selected area.
  • the angle markings denote, for example, the middle position, i.e. the exact 90 ° cut as well as further angular positions up to a maximum angle of 45 ° to the vertical. This means that practically all bevel cuts that usually occur can be made.
  • the respective angular position is easy to fix if a clamping screw with a turning handle is inserted through the half-shell-shaped body in a threaded bore and can be pressed with its end face against the disk surface.
  • a resilient catch provided with a handle can also be provided, which engages in the relatively common relative angular positions in corresponding recesses in the disc, so that the latter is immediately locked in these angular positions.
  • Usual angular positions are, for example, starting from the vertical 22.5 °, 30 ° and 45 ° to the left or right.
  • the saw table can have support walls projecting upwards in the longitudinal direction, as is customary in miter cutters. These support walls must have corresponding recesses only in the range of movement of the saw.
  • a supporting wall is preferably arranged above on the side of the saw table facing away from the operator, as is customary in miter saws.
  • This supporting wall serves to clamp and clamp the workpieces, for which purpose clamping devices and the like can also be provided in the saw table, as is customary in the prior art.
  • the disc together with the half-shell-shaped body, is longitudinally displaceable and fixable in a guide directed parallel to the longitudinal direction of the saw table.
  • the guide in a side wall of the saw table is designed as a guide rail, into which a guide rod is inserted, which can be clamped with handles against the guide rail by means of clamping screws, and which holds the disk and the half-shell-shaped body.
  • each relative displacement position can be set and fixed within predetermined orders of magnitude.
  • the side wall of the saw table has latching holes and the half-shell-shaped body has a latch with a handle which can be latched into one of the latching holes depending on the relative displacement position.
  • the inventive device for sawing workpieces consists essentially of a flat saw table 1, which is made of metal and can be occupied with relatively softer contact surfaces 2.
  • the support surfaces are only arranged in the area that cannot be covered by the saw 3 described later, whereby the gradation of support 2 and saw table 1 creates a space for the saw blade of the hand saw 3 to pass when sawing through a workpiece.
  • a hand saw only shown schematically, is held above the saw table, the hand saw being held in a guide 4 so as to be longitudinally movable and vertically displaceable.
  • the guide 4 consists essentially of two guide rods arranged on both sides of the saw table 1, into which bearing eyes attached to brackets of the hand saw engage, so that the hand saw 3 is held in a longitudinally displaceable manner and can be moved vertically, but is otherwise held captively.
  • Such guides are common and known in miter saws.
  • the guide 4 is arranged to be rotatable and lockable about a horizontal axis 5, the axis 5 being parallel to the longitudinal extent of the saw blade of the hand saw 3 is directed and is arranged approximately in the plane of the saw table 1.
  • the guide 4 further comprises two disks 6, which are held coaxially to one another on opposite side surfaces of the saw table 1 in the drawing figures 1 and 2 and are each rotatably mounted in a half-shell-shaped body 7.
  • the body 7 has an essentially V-shaped cutout, which is clearly visible in particular in FIG including hand saw 3 is present.
  • the discs 6 also have an engagement cutout for the saw blade of the hand saw 3, the guide rods 8 for the guide eyes, not shown, which are mounted on the bracket of the hand saw 3, being fastened to the discs 6. These guide rods extend at right angles to the longitudinal direction and parallel to the side surface of the saw blade of the hand saw 3.
  • the disks 6 are different by means of a spring-loaded catch 9 with a handle 10 relative angular positions can be locked relative to the body 7.
  • the disk 6 has a plurality of latching recesses 11, which define frequently occurring angular positions, for example deviating from the vertical, 22.5 °, 30 °, 45 °, respectively to the right and left.
  • the spring-loaded catch 9 engages in the respective recess 11 and can be released from it by pulling the handle 10.
  • the catch can also be locked in a release position, so that the rotational mobility of the disc 6 is then unaffected by the catch 6.
  • the disk 6 can then be additionally locked by a clamping screw 12 with a turning handle 13 which penetrates the half-shell-shaped body 7 in a threaded bore and can be pressed with its end face against the disk surface of the disk 6.
  • the disc 6 has angle markings 14 on the front surface which interact with a marking 5 of the body 7. The angle markings 14 are visible through a window 16 of the half-shell-shaped body 7.
  • the guide rod 20 is locked or released by means of clamping screws 21 with handles 22 by tightening or removing the clamping screws against the guide rail.
  • the clamping screws 21 are held in threaded holes in the half-shell-shaped body 7.
  • the side wall 18 of the saw table 1 also has latching holes 23 and the half-shell-shaped body 7 is provided with an additional latch 24 with a handle 25, which latch is spring-loaded and cooperates with the latching holes 23 at a corresponding angular position.
  • the arrangement of the locking holes again corresponds to conventional miter cuts of, for example, 60 ° and 45 ° and the central position 90 °.
  • the invention is not limited to the exemplary embodiment, but is variable in many ways within the scope of the disclosure.
