The main working procedures include trimming the tube nozzle, processing nozzle thread, polishing tube shoulder and length trimming to required length.
Germ tubes from charging conduit are pushed and inserted over mandrel. The expand mandrel expands to fasten the tubes on the mandrel and revolves at high speed with the tubes. During the procedure, the tube end is trimmed by the knife to the required length. The tube nozzle is trimmed. The tube forms reuquired thread by another knife. Next, the brush driven by motor polishes the head and shoulder of the tubes and the body of tubes is made smooth and straight, which is helpful for unloading tubes.
The last working station is for unloading materials. The unloading board controlled by cam pushes the processed tubes out from the mandrel. Following the flat belt, the tubes come to the charging conduit which can connect with conveyor chain of annealing oven.
A. Tube diameter range: φ11mm-φ38mm
B. Tube length range: ≤185mm
C. Production speed: ≤60tubes/min
D. Motor power: 2.2KW

A. Ferguson indexer increases indexing accuracy. The machine has high abrasion resistance and low working noise.
B. Function of putting tube in twice and separating tube’s body and end automatically. The waste removal device automatically collects aluminum scraps in the waste drum.
C. SIEMENS PLC controls speed and frequency and displays information like production speed on its text panel.
D. Frequency converter is used to control the speed and it is convenient to replace mandrel of different types. Mandrel board and mandrel are processed by CNC equipment, which increases the stability of the machine.
