Pieces of drawing
This tube drawing machine includes transmission system, draw bench,
drive of drawing
car, feeding table, dies container, mandrel system and electric
3.1 Transmission system
The whole line is driven by a DC motor with power of 75kw through
3.2 Draw bench
Draw bench is the main body of the machine. Main components are
frame, drawing car,
toothed rack. There are liner guide rail and sliding block to make
sure a straightening
drawing. Pneumatic clamp is on the drawing car to connect and clamp
the triple tubes.
3.3 Drive of drawing car
The drawing car is driven by AC motor thorough toothed rack.
3.4 Tube prop rack
Pneumatic prop rack spins out to hold the tubes between dies and
3.5 Tube feeding table
Tube feeding rack combines tubes table and pushing table. The tubes
are pushed to the
pushing table form tube table manually. Front tip of the mandrels
get raised to pick up
the tubes. After the tubes are well received by the mandrels, they
are sent to the dies for
3.6 Dies container
Dies container locates between mandrels and drawing car. There are
three dies in it with
straightening adjusting device.
3.7 Mandrel System
Mandrel system is a complex of mandrels, adjusting mechanism,
pneumatic drive equipment.
4. Electric control
Electric control system adopts digital motor control system and PLC
to ensure a stable
producing. Malfunction like overcurrent or speed lost control is
under supervision. Procedures
are in interlock sequences.
