Abstract

943,918. Angular bending. HILMOR Ltd., and E. J. HAMPSON. Feb. 24, 1961 [Feb. 26, 1960], No. 6828/60. Heading B3E. A bending machine of the kind comprising a main support structure, a former carrier adapted to have a former mounted on it and to rotate about an axis fixed with respect to the main support structure, a grip carrier adapted to have a grip mounted on it for rotation about the axis, and for movement along a path 7 at right angles to, but spaced from, the axis is characterized in that a main drive means is positively connected through a toggle mechanism to move the grip carrier in one direction along the path of movement and is then positively connected to rotate the former carrier and grip carrier about the axis. A tube 9 to be bent around a former 12, on a carrier 12a, is clamped thereagainst by a grip 13 on a table 14 slidable towards the former 12 on a turn-table 11. The grip 13 has a fine adjustment by an eccentric 16 in a housing 15 and the housing 15 has a rough adjustment on serrations on the table 14. The machine is driven through a sprocket 24 keyed to a drive wheel 18 carrying a crank-pin 19 connected by a link 21 to a pin 22 on the table 14, the pins and wheels being contained in an oil bath in the machine frame 10. As the wheel 18 is rotated it first moves the clamp 13 towards the former 12 by means of the link 21 and then a projection 20a on the wheel 18 engages a stop 23a on the table 14 to rotate the table 14 and thus the former 12 about an axis 25 to bend the tube, keys 52 on the table 14 engaging flat sides 52 of a boss 65 on the former carrier 12a. A guide structure 26, carrying a pressure die to bear on a straight portion of the tube 9 adjacent the bending head, is moved towards the former 12 by eccentric and gear means described in Specification 943,916, to which reference is made, and driven from the gearwheel 18, so that such movement is completed simultaneously with or before completion of the inward sliding movement of the table 14, a fixed wiper die may be carried on a support 33. The table 14 may be positioned for left or right-hand bending by spring loaded catches 37 on the machine support structure receiving rollers carried by lugs 35 on the edges of the turn-table 11.
