Abstract

751,971. Bending-jigs. BAARSEN, A. VAN. Jan. 29, 1954, No. 2719/54. Class 83 (4). [Also in Group XXIII] A device for use in bending metal bars comprises a longitudinally extending clamping bench in which a number of separate bending- jigs are clampingly secured at adjustable distances from one another, each bending- jig comprising a casing and a pair of bending-pegs projecting upwardly from said casing. Each bending-jig comprises a pair of pegs 1, 11 on the end of a block 2 longitudinally slidable in a cylindrical casing comprising an inner sleeve 6 and an outer sleeve 8 welded to end plates 10, 11, the plate 11 projecting as a flange beyond the sleeve 8. The block 2 has rack teeth 3 which mesh with a sector 4 extending through a slot in the casing and rocked by a handle 16. The outer sleeve 8 of the casing is held in a resilient frame comprising two clamping blocks 13 connected by spring strips 15 so that the jig may be rotated in the frame to adjust the pegs 1, 1<SP>1</SP> when there is no pressure on the blocks 13. A number of jigs are placed a suitable distance apart between beams 14 of a clamping bench with the flanges of the plates 11 resting on the beams and the angle of the base line between the pegs 1, 1<SP>1</SP> of each jig with the longitudinal axis of the clamping bench adjusted according to the thickness of bar to be bent. The tools are then clamped in position between the beams 14 by bolts 18. A bar, or bars, 19 is placed between the pegs and its end is bent, by suitable means, around a peg of the end jig to form the first bend. The pegs of this jig are then lowered by the handle 16 and the bar bent about a peg of the next jig and so on.
