Definitions

  • the invention relates to the machine frame saw, sgn. Gates used to divide the clippings is intended for thin plate-shaped slats.
  • the machine frame saws are known to consist of a lower table and two fixed ones Gate stands, which are arranged on the under table and provided with saw frame guides are in which the frame frame equipped with parallel saw blades moves vertically.
  • the drive the vertical movement of the gate frame is connected to the crank mechanism by a stilts and performed electric motor, which is arranged in the under table.
  • the saw blades in the frame are reduced to a minimum Vertical tilt attached so that first the upper parts of the saw blades engage in the cut, and only then do their middle and lower parts engage in the cut.
  • Machine saws of another type are also known, in which the Frame is not guided in the saw frame guides between the frame stands, but it is without saw frame guides on pins in the lever gear, on the principle of Parallelogram.
  • the gate frame moves both in the vertical, as well as in the horizontal direction, and movement back and forth in horizontal direction improves the cutting conditions because the sawdust at the Return movement from the frame from the tooth gaps of saw blades can fail.
  • the disadvantage of this solution is that the guidance of the gate frame in the system is then one granted less directional stability to the gate frame, and also from the point of view of idling and this solution is not optimal for the total service life.
  • the above Disadvantages are eliminated by the machine frame saw according to this invention, which known manner from a lower table and two fixed, arranged on the lower table, Gate stands exist.
  • the gate frame is guided vertically in the saw frame guides and driven by a stilts connected to the crank mechanism on the gear shaft.
  • the essence of the invention is that the fixed gate stands with the diametrically arranged interconnected, movable gate gauges are provided in the gate stands with the possibility of horizontal movement are arranged and with the drive of this movement are connected.
  • the saw frame guides in which the frame frame moves vertically are not connected to the fixed gate stands, but they are on the movable gate gauges attached.
  • the arrangement of movable gate gauges in fixed gate stands is convenient executed that upper arms are created in the upper part of the movable gate gauges, which on the Pins are fixed pivotally in fixed frame stands. Forearms are created in the lower part, which are suspended by levers on the shaft arranged in the fixed frame stands.
  • the Movable gate gauges are pivotable in a horizontal direction on the upper pin, the Swing initiator is the shaft swiveling, which is transmitted to the forearms via levers becomes.
  • the drive of the pivoting movement of movable gate gauges in the horizontal direction can usually be solved in different ways.
  • the advantages of a machine frame saw according to the invention are in particular that the gate frame, on the one hand, performs the usual vertical cutting movement, on the other hand also performs the movement in the horizontal direction, since the saw frame guides on the Movable gate gauges are attached, which perform a horizontal pivoting movement.
  • the gate frame then guides the cut feed (when moving downwards) and the cut removal (when moving up).
  • FIG. 1 is the schematic axonometric view of the machine frame saw with the swivel drive through the cam and the hoist, in the covered state without auxiliary equipment, e.g. B. feed devices, etc. 2 shows the side view of this saw
  • FIG. 3 shows the side view of a Machine frame saw with the swivel drive by the stepper electric motor, in the covered Condition without auxiliary systems.
  • the invention is based on examples of the execution of a fine-cutting machine frame saw, shown with the kerf with a thickness of 1.1 - 1.6 mm, which is particularly suitable for cutting thin plate-shaped slats is suitable. With these examples, however, are not all Uses of the invention exhausted, not only in fine-cut, but can also be used with medium or large machine frame saws.
  • a machine frame saw consists of a lower table 1 and of fixed frame stands 2, 2 ' , which are arranged parallel to one another on the lower table 1 .
  • the fixed gate stands 2, 2 ' the movable gate gauges 3, 3' are arranged against each other, which have a possibility of slight pivoting (2-5 mm) in the horizontal direction.
  • the diametrical fixed gate stands 2, 2 ' and the movable gate gauges 3, 3' are connected to each other by spacers 16, 17 , which ensure the rigidity of the construction.
  • the arrangement of movable gate gauges 3, 3 ' in the fixed gate stands 2, 2' is designed such that the upper arms 6 of the movable gate gauges 3, 3 'are pivotally arranged on the pin 7 in the fixed gate stands 2, 2' .
  • the forearms 8 of movable gate gauges 3, 3 ' are suspended on the levers 9 on the shaft 10 which is rotatably arranged in the fixed gate stands 2, 2' .
  • the saw frame guides 4, 4 ' are fastened on the facing sides of movable gate gauges 3, 3' , in which vertical backward movement of the gate frame 5 is carried out, in which the saw blades, not shown, are clamped.
  • the vertical movement of the gate frame 5 is ensured by the stilt 18 from the crank mechanism 13 , which is driven by the main electric motor (not shown), which is arranged in the lower table 1 .
  • the horizontal movement of the gate frame 5 is the result of pivoting movement of the movable gate gauges 3, 3 ' in the fixed gate stands 2, 2' .
  • This pivotal movement can be driven in various ways, e.g. B. mechanically or electrically.
  • An example of the mechanical drive is shown in FIGS. 1 and 2.
  • One end of the lever gear 11 is firmly connected to the end of the shaft 10 , and the rotary movement is transmitted via the lever pivot 9 and the forearms 8 to the lower part of the movable gate gauge 3, 3 ' .
  • the upper part of movable gate gauges 3, 3 ' is rotated only on the pin 7 .
  • the total movement of the gate frame 5 results from the combination of vertical movement in the saw frame guides 4, 4 ' and horizontal pivoting movement of movable gate gauges 3, 3' .
  • FIG. 3 also shows an alternative example of the execution of driving the horizontal component of the movement of the gate frame 5 with the stepping electric motor 15 , which acts on the lower part of a movable gate gauge 3, either directly or via the pull rod 18 .
  • the machine frame saw according to the invention can e.g. B. as a fine-cut saw Production of parquets, multi-layer panels, for the production of door, window, furniture, Gymnastics or climbing components etc., and then most of the others Jig saws can be used.
