Definitions

  • the invention describes an adjustable band saw with multiple cuts. Facilities of this type are not yet known. Only band saws are known which have a circumferential blade that has an interface per blade. A characteristic of this well-known
  • Band saw is that the band saw blade is turned and turned by almost 50 to 60 degrees, sometimes even 90 degrees from the vertical plane after leaving the interface, so that the materials to be cut can be pushed under the returning strand.
  • Considerable portions of the drive power are used for the twisting deformation of the saw blade and the wear of the saw blade in the vertical brackets is also extremely high.
  • the brackets themselves are used very unfavorably.
  • the necessary twisting of the band saw blades is opposed by the use of sufficiently high and thick band saw blades equipped with higher cutting capacities.
  • the band saw blade is also not used optimally with only one interface.
  • the object of the present invention is to prevent the known disadvantages of the known band saws and to create a band saw with higher performance and better saw blade use.
  • the object is achieved in that the band saw blade rotates vertically on horizontally lying rollers, namely over the entire circumference, without being twisted and the returning strand via two guide rollers which can be adjusted at right angles to the strand, parallel to the other part of the band saw blade in each Any distance can be moved and thus a second interface of the same band is created.
  • the cutting performance can be increased by the non-positive design of the band saw blades in cooperation with the correspondingly shaped drive and deflection wheels.
  • Higher band saw blades can also be used, which increases the bending stiffness in the cutting zone and thus speeds up the workpieces.
  • the performance of the invention is obvious.
  • Band saw increased by double or four times compared to other band saws due to the double or quadruple cutting arrangement.
  • the new invention is distinguished from the known band saw machines by a multiple increase in performance.
  • the invention will be described in detail with reference to the drawing.
  • Fig. 1 shows a plan view of the arrangement of the band saw blade guide according to the invention.
  • Fig. 2 shows a double version of the band saw according to the invention in plan view.
  • Fig. 3 shows a tandem arrangement side by side.
  • Fig. 4 shows a side view of Fig. 1 and the foldable part of the band saw for performing long workpieces with a single cut.
  • Fig. 5 shows the formation of the band saw blade for frictionally driving the same.
  • FIG. 1 shows the drive wheel (1) with the drive motor (2) and the rigid deflection wheel (14) very clearly in plan view. You can see that the two wheels (1 and 14) are wrapped vertically all around by the band saw blade (3) and you can also see that the deflection rollers (4), which are attached to the crossbar (5), parallel to the band saw blade (3) can move and lead to each other. This creates the interfaces (6 and 7) which simultaneously cut the two pieces of material (13) from the workpiece (9). The workpiece (9) can be passed through the interfaces (6 and 7) either laterally in the standing version of FIG. 1 or from below or above in the lying version of FIG. 1.
  • the cross-beam (5) is preferably adjusted via the hydraulic cylinder (10).
  • the tensioning cylinder (8) automatically and continuously compensates for the lengthening of the band saw blade, which inevitably occurs when the cross-beam (5) is moved.
  • FIG. 2 shows a tandem or double version with four interfaces. Also here applies that Fig. 2 can be carried out either standing or lying horizontally. It can be seen very clearly here that two systems of FIG. 1 are arranged opposite each other in a mirror image, and that the systems themselves can be adjusted against each other in the parallel guides (11) with the hydraulic cylinder (15). It can be seen very clearly that four workpieces (13) can be produced simultaneously in the embodiment according to FIG. 2. In Fig. 3 you can see a variant in double design, which is not opposite, but next to each other. There you can see the large deflection wheel (12), which is identical in diameter to the drive wheel (1) and the deflection wheel (14) of FIG. 1. This arrangement has the advantage that different materials can be cut twice on each interface at the same time .
  • FIGS. 1 to 5 clearly show the essence of the invention.

Abstract

Dans le but d'augmenter le rendement d'une scie à ruban, on prévoit de faire circuler verticalement le ruban de la scie autour de poulies fixes (1, 14) disposées horizontalement et de créer un deuxième lieu de coupe (7) avec la section de retour du ruban qui est déplacée parallèlement contre la première section du ruban par deux poulies (4) disposées à 90o par rapport au ruban. On peut aussi augmenter le rendement de la scie à ruban par deux dispositifs de ce genre disposés symétriquement et aussi déplaçables l'un contre l'autre. Le rendement de la scie à ruban est aussi augmenté en prévoyant sur les roues de commande du ruban des saillies (17) qui accrochent dans des évidements (16) du ruban.
