Tube end forming and thread rolling

Machines that reduce, expand and form tube ends and roll threads – handles, poles, furniture and exhaust tubes.

  AONA Automatic Tube Loading, Swaging and Thread Rolling Line

  The line feeds the tube, swages the end and rolls an external thread. AONA lists a base range of Ø10–60 mm with options for the tube size and thread type. A typical part is a tubular handle or pole that screws into a fitting. The reduced diameter, thread length and transition to the full tube need to match the assembly drawing together. Evaluate accepted parts after all three operations. Provide the incoming length, material and wall thickness. Ask for a sample that fits the actual connector and record the changeover time between sizes.

  AONA AN-PTR200 Thread Rolling Machine for Tubes and Bars

  The AN-PTR200 forms straight external threads on tubes or bars with two rolling dies. Match the roller set to the thread form, pitch and blank size. The hollow drive design provides through-feed for long stock. Confirm the available clearance and support on both sides of the machine, along with the thread length required on the finished part. Have the supplier roll a sample using your actual material. Check the thread with an appropriate gauge and the mating component used in assembly.

  AONA TM120NC Hydraulic Tube End Forming Machine

  The TM120NC is a hydraulic tube end former. The tooling determines whether the end is reduced or expanded. AONA lists PLC control and a servo die change drive for the documented configuration. For a telescoping assembly, specify the diameter after forming and the insertion length into the mating part. Include a longitudinal section of a transition end so the supplier can see where the geometry changes. Request samples of the most demanding size in the run. Measure the formed length and concentricity, then check the fit with the actual mating tube.
