Composition and Characteristics of Fully Automatic Three Wire Cold Drawing Machine
Cold Drawing Machine is mainly composed of feeding table、receiving tank frame、push rod device、core rod lifting platform、mandrels front and back adjusting device、drawing die holder、body、drawing trolley、main drive device、discharge conveying chain device、automatic collecting rack for finished tubes、etc.
While drawing pipes、if the detection device of feeding table senses no mother tubes、the lifting basket will lift for falling the mother tubes into the stop gauge.Once mother tubes available in the table、the lifting basket will automatically declines and receiving tank back plate will rise.The gear and top material device will distribute the mother tubes automatically to the receiving tank in the receiving rack、which has taper.The roller of receiving tank will push the mother tubes into back plate by lifting cylinder、and then pressure cylinder presses the end of mother tubes .Meanwhile、the mandrel lifting platform lifts to the center of threading bar、the first stroke cylinder of core rod holder will push mandrels into the bore of mother tubes、and then push trolley of receiving platform will quickly push the mother tubes passing into the core rod、the core rod lifting platform will decline to drawing center line.At the same time、the first stroke cylinder automatically push 3 pieces cylinders、core rod、mandrels and tube pull head of slide board through the die hole.After the waiting drawing trolley in the die receives the controlling signal from first stoke cylinder、the jaw cylinder pushes jaw clamping tube ends.The main motor starts for driving reduction box to chain wheel and trolley for drawing、meanwhile the second stroke cylinder is out for drawing.After finishing drawing、the tubes will fall into the lifting & receiving device and decline、meantime the conveying chain of discharge conveying device will move for declining、and the finished tubes will fall into the auto declining collecting rack、which has detection platform.While detecting finished tubes、the operator presses the buttons for detection、Meanwhile the drawing trolley will quickly return to die holder for next cycle.
