Hydraulic Type Tube Expander Machine Vertical Installation for HVAC Application
1. Equipment Characteristics
1.1 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.
1.2 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.
1.3 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.
1.4 The vertical tube expansion machine adopts expansion rod protection device which could stop the machine automatically in
case of bended expansion rods.
1.5 The expansion rods adopt double-clamping device to prevent looseness during expansion process.
1.6The vertical tube expander machine adopts guide column and slide rail for guidance, which has a high precision and strong
1.7 The vertical tube expander machine is equipped with a manual door for easy installation of products.
2. Equipment Components
2.1 The main pneumatic components of the equipment are of ALLGREATor AIRTAC brand.
