Abstract

749,389. Shearing. LABAN, W. H., and BROOKES (OLDBURY), Ltd. Nov. 3, 1954 [Aug. 22, 1953], No. 23187/53. Class 83 (4). Means for shearing a tubo 15 comprises a mandrel 19 and a collet 14 for supporting the tube internally and externally, the inner end face 20 of the mandrel forming an internal shear blade with which co-operates an external ring cutter 31 which is freely rotatable in a circular opening in a plate 22 to which is imparted an orbital motion in a plane perpendicular to the axis of the tube, the opening 33, Fig. 1, in the cutter having the form of a circle the centre of which is displaced from the axis of the tube, the opening 33 having an arcuate recess 34 the radius of which is substantially equal to that of the outer surface of the tube. The orbital motion of the plate 22 is produced by crank pins 24, Fig. 1, rotatably mounted in spaced bores in the plate and carried by shafts 26 which are driven by means of worm wheels 28 engaging worms 29 on a common driving shaft 30. The plate 22 is mounted in a housing formed by two plates 10, 11 bolted together and mounted on a base 12.
