Abstract

904,645. Bending tubes; flexible mandrels. ARBOGAST, A. C. Oct. 28, 1960 [Dec. 8, 1959], No. 37130/60. Class 83 (4). A method of bending a tube comprises the steps of inserting the tube into the feed end of an elongated passage having an intermediate curved tube-shaping portion, inserting a resilient filler into said tube, advancing the tube in said passage from said feed position to said curved tube-shaping portion, and simultaneously pressing against the leading end of said filler within said tube to expand it radially into tube-supporting relation as said tube is advanced. A tube blank 20 is introduced into a die 30 with its bevelled end 22 foremost. A resilient member 54, e.g. of rubber, secured on the end of a pusher 44 is inserted into the tube so that a shoulder 48 on the pusher 44 abuts the tube end. A reactance member 56 is inserted into the other end of the die 30 so that a spherical head 62, on a shank 64 pivoted at 66 to the member 56, engages the end of the resilient member 54. Hydraulic pressure is then applied to the pusher 44 and, to a lesser degree, to the reactance member 56 to cause the resilient member 54 to expand and grip the tube internally and the member 44 to push the tube through the bend 42, so bending the tube. The pusher 44 and member 56 are then withdrawn, the head 62 on the latter restoring to shape any parts of the leading edge of the tube curled during the bending operation. The die 30, which is in two halves, is then opened, and the bent tube withdrawn. The end portions of the bent tube may then be flared. The head 62 may be offset from the axis of its shank or may be formed integral with the reactance member. U.S.A. Specification 3,701,002 is referred to.
