  • FIG. 2 is a plan view of the vise of the present invention, in which a movable vise jaw is shown as separated the maximum distance from a fixed vise jaw.
  • FIG. 3 is a sectional view taken substantially along the line IIIIII of FIG. 2 and having parts thereof broken away to illustrate details of construction.
  • FIG. 4 is a view similar to FIG. 3 but differing therefrom in that in FIG. 4 the vise jaws are illustrated as being clamping a smaller material than shown in FIG. 3, which is shown as being cut by a bandsaw blade.
  • FIG. 5 is a sectional view taken along the plane of the line V-V of FIG. 3.
  • the numeral 1 designates generally a bandsaw machine which is conventional in that an endless bandsaw blade 3 trained over a driving wheel 5 and a driven wheel 7 mounted within a housing 9 is lowered with the guide of saw guides 11 and 13 towards a material M to be cut which has been placed on a work table mounted on a base 15.
  • an elongate base frame 17 which comprises elongate walls 17fand 17r having elongate plates 19 and 21, respectively, secured thereon.
  • elongate plates 19 and 21 are grooves l7wf and l7wr (as shown in FIG. 3).
  • FIGS. 1 and 2 there is shown a fixed vise jaw 23 comprising a front jaw element 23f and a rear jaw element 23r which is so mounted on the top end of the base frame 17 by means ofbolts 25 as to form a vertical elongate opening, or slot, 23v0 between the jaw elements and also to form a horizontal wide opening 23110 above the right end of the base frame 17 as viewed in FIG. 2.
  • a movable vise jaw 27 is bifurcated into a front jaw element 27fand a rearjaw element 27r to form a vertical elongate opening or slot 27v0 and the vise jaw 27 is constructed as an integral part of a movable support block 29.
  • support block 29 On both sides of support block 29 are horizontal elongate flanges 29ff and 29fr which are slidable along the grooves l7wfand l7wr, respectively.
  • the fixed vise jaw 23 and the movable vise jaw 27 are so designed that the vertical elongate openings 23v0 and 27v0 are formed in the vicinity of the centers of the tops of the vise jaws and extend downwards to the top surface of the movable support block 29.
  • the vertical centers of the vertical elongate openings 23v0 and 27v0 are located in alignment with the plane of the cutting area of the bandsaw blade 3 so that the saw blade 3 can be moved therethrough during the cutting operation without hindrance.
  • the movable vise jaw 27 is movable integrally with the movable support block 29 which is slidable along the grooves l7wf and l7wr towards and away from the fixed vise jaw 23.
  • the two vise jaw grip the material M to be cut.
  • the bandsaw blade 3 can be moved through the vertical elongate openings 23m and 27v0 of the vise jaws 23 and 27.
  • the movable support block 29 has at its left end a lowered portion, or depression, 29d and at its right end an inclined chute 290 down which cut chips can slide. Also, support block 29 is provided on the underside with a rack 31 which will be described later.
  • the movable support block 29 has on its upper surface a channel-like groove 29g'which is as wide as the vertical elongate openings 23vo and 27v0 of the jaws 23 and 27 and extends from the bottom of the vertical openings 27v0 towards the fixed vise jaw 23, allowing the bandsaw blade to be run therethrough without damaging the upper surface of themovable support block 29 upon completing the cutting of the material M.
  • the movable support block 29 is adapted to serve as a work table for supporting the material M and also to serve as an integral part of the movable vise jaw 27 to clamp the material M in cooperation with the fixed vise jaw 23.
  • the base frame 17 is provided at its left end with a support plate 33, on which is mounted a single-acting hydraulic cylinder 35 formed with a hydraulic fluid port 35p connected with a conduit 37 for hydraulic fluid.
  • a piston rod 39 secured to a piston 41 within the hydraulic cylinder 35 extends into the interior of the base frame 17 through openings through the support plate 33 and the base frame 17.
  • a return spring 43 is provided around the piston rod 39 within the hydraulic cylinder to bias the piston 41 towards the port 35p.
  • an arm 45 Pivotally connected to the end of the piston rod 39 through a pin 47 is an arm 45 which has at its free end a pawl 45p to engage with the rack 31 provided on the underside of the movable support block 29.
  • a roller 49 is rotatably provided at the free end of the arm 45 through a pin 51.
  • a plate spring 53 having a sloped portion 53s is so provided as to be located in the vicinity of the free end of the arm 45 when the piston rod 39 is retracted as far as possible towards the exterior of base frame 17.
  • the roller 49 provided at the free end of the arm 45 rolls up the slope 53s of the plate spring 53 so that the pawl 45p of the arm 45 can engage with the rack 31.
  • the material M to be cut is placed on the movable support block 29 in contact with the fixed vise jaw 23 in such a manner that the portion to be cut or the kerf line to be made on the material is located in the cutting plane of the saw band 3 through the vertical centers of the vertical elongate openings 23v0 and 27v0 of the vise jaws 23 and 27. Then, the movable vise jaw 27 is manually moved into contact with the material as shown by the broken lines in FIG. 3. Next, when the hydraulic fluid is delivered from the conduit 37 into the hydraulic cylinder 35, the piston 41 will be forced against the bias of the return spring 43 to move the piston rod 39 and the arm 45 connected therewith into the interior of the base frame 17.
  • the roller 49 is forced to roll up the sloped portion 53s of the plate spring 53 to bring the pawl 45p of the arm 45 into engagement with the rack 31, and the movable vise jaw 27 is directed towards and against the material M which is in contact with the fixed vise jaw 23.
  • the fixed vise jaw and the movable vise jaw are located on the area of both sides of the cutting plane of the band saw.
  • the bandsaw blade 3 is started and lowered through the vertical elongate openings 23v0 of the fixed vise jaw 23 and 27vo of the movable vise jaw 27 to cut the material M.
  • the saw guides 11 and 13 continue to be easily lowered because the horizontally wide opening 23h0 is provided above the right end of the base frame 17 as viewed in FIG. 2 and the depression 29d is provided at the left end of the movable support block 29 as viewed in FIGS. 3 and 4.
  • the movable support block 29 is provided on its upper surface with a channel-like groove 29g through which the saw blade 3 can move, the saw blade 3 can cut completely through the material M without damaging the movable support block 29.
  • the hydraulic fluid of the hydraulic cylinder 35 is opened to atmospheric pressure, and the piston 41 and the piston rod 39 are retracted by the return spring 41.
  • the arm 45 disengages with the rack 31 during the retraction of the piston and piston rod.
  • the movable vise jaw 27 is free from clamping pressure and can be manually moved out of contact with the material M.
  • the vise apparatus is so designed that the material M to be cut is clamped on both sides of the plane of the cutting area of the bandsaw blade 3. Accordingly, even if the material M has become very short as a result of several cycles of the cutting operation, it can still be firmly gripped by the vise, and therefore one piece of material can be completely used and cut into regular workpieces without being scrapped. Thus, the material can be most economically cut and used. Since the end portion of material to be cut from the main body of material is also held, the piece cut from the main body of material can not suddenly drop down from the vise or the work table and cause an injury. Moreover, since the rack 31 for forcing the vise faces downward, it can not get clogged or damaged by cut chips coming from the cutting operation.
