Title: Improvement in method and means for forming rectangular flexible metal tubing
IPC: B21C37/12
Filed: 1947-05-16
Abstract: 623,845. Making corrugated, helicallyjointed, non-circular tubes. TITEFLEX, Inc. May 16, 1947, No. 13297. Convention date, June 6, 1946. [Classes 83 (ii) and 83 (iv)] Angular bending ; coiling; seaming; soldering.-Corrugated flat sided non-circular tubing is made by helically winding a metal strip preformed with. interlocking edges on a flat arbor which is rotated intermittently, the corner of a convolution and the flat side being seamed during the periods of rotation and dwell respectively. A power-driven rectangular arbor 15 is rotated intermittently anticlockwise and draws a strip 17 from a coil 22 through guide rolls 23, 24, 25, and section bending rolls 26, 28, 30. A reinforcing wire 18 and a solder thread 19 are positioned by guide rolls 32, 33 and wound with the strip on the arbor. The intermittent rotation of the arbor is effected by an electromotor through a Geneva mechanism giving unequal rotations from a constant speed shaft 57 carrying cams 67, 68, 69. The cam 67 reciprocates horizontally a carriage 80 supporting the rolls 26, 28, 30 and guide rolls 35, 37 for the solder thread and reinforcing wire. The cam 68 reciprocates seaming rolls 20, 21 carried on slides 87, 88, slidable'in blocks 89, 90. The cam 69 rotates a pinion 94 engaging racks supporting the blocks 89, 90. As the arbor rotates counterclockwise the upper seaming roll 20 is moved upwards and to the left and the lower roll 21 is moved downwards and to the left by the cams 68, 69 to effect seaming of the upper right and lower left corners of the tube. The arbor then remains stationary and the roller 20 moves to the right and the roller 21 moves the left to seam the flat sides adjacent the corners. The Geneva mechanism provides for the short and long dwells necessary for seaming the short and long sides of the tube. As the supply reels for the strip, wire and solder are rotated at constant speed and the arbor rotates intermittently means is provided for maintaining constant tension on the strip 2. The cam 67 reciprocates the forming roll carriage 80 to the right or left at a speed to maintain constant withdrawal from the reels. A gas burner 130 mounted below the arbor runs the solder thread after seaming. The formed tube is stripped from the mandrel by the movement of the rod 21. Tubes of triangular and other shapes with straight sides and rounded corners may be similarly formed. If strip accumulates on the mandrel a lever 127 is operated by the strip to stop the machine.
