Abstract

14,530. Bright, F. E., [Blakeslee, J. R.]. July 1. Metal tubes. - The invention consists of means for upsetting the ends of boiler tubes and similar articles. The operation is performed in two stages, by means of dies which are made in halves and clamped together. The hollow a is made up approximately of the ultimate shape of the tube, and has a taper portion b in which the upsetting takes place. The operation is performed by a taper mandrel D having a shoulder d<1>. The final shaping takes place in the next die a', which is of the exact shape of the finished tube. The mandrel E is in this case somewhat longer than in the former one.
