Abstract

1285135 Angular bending; making tubes GROTNES MACHINE WORKS Inc 13 May 1970 [13 May 1969] 23238/70 Headings B3A and B3E Apparatus for forming a pre-cut blank 11 of metal strip into a tube comprises a rotatable mandrel 16 having a radially extending abutment 33 and clamping jaws 31, 32, a roller guide 30 spaced from the mandrel periphery and parallel to the rotational axis of the mandrel, and a second roller guide 40 parallel to the axis of mandrel rotation and shiftable towards the mandrel periphery. In operation stacked pre-cut blanks 11 are carried by conveyer 12 into an unstacking apparatus 13 having magnetic pickup units 14. A blank is then fed by conveyer 15 over the guide roller 30 into the jaws 31 32, where it is clamped by actuating hydraulic piston 36. The mandrel is rotated by a rack and pinion rotary actuator to draw the blank forward over the roller 30 and wrap it around the mandrel. When the mandrel has passed through approximately 270 degrees of rotation the tracking end of the blank is no longer constrained by the roller 30. At this point the seconf roller 40 is urged against the mandrel and the forming operation is continued until the blank is wrapped completely around the mandrel. The forming process is finished by moving a ram 43 into the space between the roller 40 and abutment 33 after which grippers 50 on a trolley 53 are actuated to remove the formed blank from the mandrel to a flash welding machine. The completed tube is then removed by a gripper 21 on a conveyer 23.
