Definitions

  • the invention is concerned with improvements in or relating to bar cutting particularly to the joint cutting of window and door bars.
  • the invention provides apparatus for the cutting of halving joints and the like comprising a machine frame including a work table, means to position a length of bar to be cut upon said table and means to present the work table and the bar to operating instrumentalities of the apparatus through relative movement therebetween, wherein said operating instrumentalities comprising a plurality of cutting means arranged at spaced locations along the work table and capable of simultaneously forming a plurality of cuts in the bar ; at selected intervals along the length thereof.
  • each cutting means comprising three cutting wheels operating in a desired sequence, all the cutting means following the sequence in a simultaneous manner.
  • provision may be made to reverse the direction of rotation of at least one of cutting wheels in order to preserve a clean cut into one or other surface of the bar as selected.
  • means are provided for adjusting the spacing between the cutting means according to the required intervals of distance between the notches to be cut in the bar, depending on the design and size of the window or door panel frame to be manufactured.
  • the work table is provided with slots formed along the path of operation of each cutting means when the table is presented thereto, and provision is made to adjust the position of said slots as required.
  • each bar may be manually placed upon the work table and positioned thereon by clamps
  • a supply device for example a hopper feed
  • each bar is fed lengthwise beneath raised bar clamping devices until a movable end stop is reached.
  • the end stop is removed, the clamps raised and the next bar is loaded.
  • the advance of the next bar causes the preceding bar to be removed from the work table.
  • Two wooden window bars 2,4 are illustrated in Figure 1. Each has a generally T-shaped cross-section and in order to form a cruciform joint has been notched for interengagement. Each bar has received three cuts, as shown on bar 4 at 6, 8 and 10 (see Figures 2 and 3).
  • Figure 4 shows apparatus arranged for cutting four such notches simultaneously in a length of window bar 4.
  • Notch cut 6 is to be made by a cutting wheel 12, notch cut 8 by a cutting wheel 14 and notch cut 10 by a saw blade 16.
  • Four sets of the cutters 12, 14 and 16 are adjustably arranged along their driving spindles (not shown) to be driven by motors (not shown) having a total output of 12 Kw at a spindle speed of 6300 r.p.m.
  • the paths of each set of cutters are shown in Figure 5 at A, B, C and D.
  • the spacing between the paths of four sets of cutters 12, 14 and 16 is determined by the desired distance between the notches on the window bar 4. It will be understood that the numbers of cutters is also determined by the design of the window i.e. the number of bars 4 incorporated therein.
  • the bar is supported upon a work table 18 of the apparatus which is arranged to be advanced toward the cutters 12, 14, 16.
  • the portions of the bar to be notched lie across slots 20 in the table 18. While these slots may be simply milled into the table at suitable standard positions, it is particularly advantageous if the position of the slots may also be adjusted so as always to lie on the paths A-D, ( Figure 5).
  • the leading edge of the table 18 is comprised by segments 22 received in a T-slot 24 of the table, the length and position of the segments being selected as required.
  • each clamp 28 is capable of adjustment lengthwise of the table to accommodate the position of the segments 22.
  • the clamps 28, which are pneumatically operated, are movable between a raised, retracted position and an extended lowered position illustrated in Figure 6.
  • the operating position of the cutters may be adjusted in unison by a cam-operated adjustment means (not shown) so as to accommodate bars of various cross-sectional areas.
  • the operating cycle of this apparatus is 12 seconds.
  • a bar 4 is loaded thereon so as to be received in the groove 26 of the segments 22. These segments have been arranged to provide slots 20 on the paths A-D, and the four sets of cutters 12, 14 16 have been positioned so that the four notches to be formed are in the correct relative positions.
  • the bar 4 is positioned against an end stop (not shown) to one side of the table as viewed in Figure 5.
  • a safety cover 30 ( Figure 4) is then lowered and the operator must then simultaneously operate two start buttons 32 for safety reasons.
  • the clamps 28 then advance and are lowered to clamp the bar 4 as shown in Figure 6.
  • the work table 18 is then advanced as shown by the arrow E in Figure 6 until the portions of the bar 4 which bridge the slots 20 contact the wheels 12 and 14. Further advance of the table under the influence of an adjustable hydraulic damping valve arrangement thus results in the cuts 6 and 8 being formed and brings the bar into contact with the saw edge 16 to form the cut 10.
  • the set and direction of rotation of the cutter teeth may be reversed if desired. This is because the edge cut on entry of the cutter or saw teeth is often cleaner than the exit edge and the appearance of one surface of the finished window may be visually more important as selected.
  • the operation may be automated by providing a retractible end stop and supplying bars from a hopper feed means in an end-to-end loading sequency along the table. Whichever arrangement is selected, all the notches of any one bar are formed simultaneously.
