2. Equipment Characteristics
2.1 structural type: The vertical tube expander machine is of a
vertical structure. The machine could finish tube
expansion, tube end forming, and tube edge folding during one
clamping.
2.2 The secondary end-forming length is adjusted by rotation
up-down movement of the expansion
screw driven by the chain and srpocket wheel, and the chain and
sprocket wheel is controlled by the
reducing gear and motor.
2.3 The expansion stroke (distance between 2 side plates) is
controlled by the stroke screw driven by
motor and worm gear. The screw is connected with the rotary
encoder.The length is changed by PLC.
2.4 The vertical tube expansion machine adopts expansion rod
protection device which could stop the machine automatically in
case of bended expansion rods.
2.5 The expansion rods adopt double-clamping device to prevent
looseness during expansion process.
2.6The vertical tube expander machine adopts guide column and slide
rail for guidance, which has a high precision and strong
structure.
2.7 The vertical tube expander machine is equipped with a manual
door for easy installation of products.
3. Equipment Components
3.1 The main pneumatic components of the equipment are of
ALLGREATor AIRTAC brand.
3.2 The hydraulic components of the equipment are of Taiwan brand
such as Janus, Risun or Yuken.
3.3 The main electrical components are of Schneider, LS, IDEC,
Kinco or other famous brand. The electrical
