V-CUT TOOLING FOR ULTRASONIC TUBE SEALER AND METHOD OF CUTTING AND SEALING A TUBE USING THE V-CUT TOOLING

摘要

A copper or aluminum tube is cut and sealed in an ultrasonic tube sealer. A section of the tube is placed laterally in a V-shaped recess of a center member of a forming tool of an anvil of the ultrasonic tube sealer. The anvil and a horn tip are brought together with the center member received in a channel of a forming tool of the horn tip to cut the tube with the cut tube having cut ends on opposed sides of the center member. At least one of the cut ends is pinched together between the forming tool of the anvil and the forming tool of the ultrasonic horn tip and the ultrasonic horn is ultrasonically vibrated to ultrasonically weld the at least one cut end together to seal that cut end.
