Clarke & Lewis UTB CL-DF-1 Double Flare and Single Flare Machine

The Clarke & Lewis UTB CL-DF1 model is a hydraulic machine designed to produce double thickness flares, single flares and upset beads. The hydraulic operation provides controlled pressure for uniform upset production. The tooling is interlocked for squetional operation, controlled by a single lever. Production rate for double flare is 600 per hour.

The Clarke & Lewis UTB CL-DF-1 is a two cylinder press. The front cylinder clamps the tube in the holding die and the rear cylinder advances forming punches through a hole in the rod of the front cylinder. An accumulator maintains constant clamp force when the punch cylinder advances. Three pressure settings are provided for clamping, upset and flare pressures, each with a gauge.  Clamping pressure holds the tube in place in the tapered holding die. The upset pressure is the first operation in double flaring to upset the tube end and the flare pressure forms the double flare. Flares can formed to 37 or 45.
