3. Brief introduction of the line
a. Simplified de-coiler
·Expand and shrink manually which could expand fromφ470 to φ510.
·It has the device to block the coils to prevent they from loosing.
·It is equipped with the brake devices to control the tension of de-coiling and avoid inertia which may cause the coils spring-shaped open.
b. 7 roller-straightener (φ125mm)
·It is divided into 2 pinch rollers and 5 leveling rollers 2 pinch rollers with 2.2kw motor drive the flat bar in to next process, while the 5 leveling rollers pre-leveling the plate to feed the flat bar more easily.
·The diameter of the rollers is φ90.
c. Chamfering and extrusion machine
·It adopts the 12 standing rollers which are divided into 6 groups , press and squeeze each side to do the chamfering and edging.
·This part also includes a 2-roller device to prevent the bar from jumping so that it can be straight to the next process.
·The diameter of the standing rollers are φ135mm and the height is 78mm.
d. Roller-pinch and press device
·It shares the equipment of flat surface straightener: gear distribution box and 30kw motor and 400 decelerator.
·The diameter of the two rollers are φ180mm, they are used to pinch and press and polish the surface.
e. Longitudinal straightener
·7 stand rollers to straighten the flat bars longitudinal bending.
·The diameter of the standing rollers are φ135mm and the height is 78mm.
f. Flat surface straightener
·It is equipped with 30KW frequency conversion control motor with 400 decelerator.
·It is composed of 2 pinch rollers (φ135mm)and 11 leveling rollers(φ125mm).
·The motor change to frequency conversion control which is cheaper and with a perfect speed and length.
g. Hydraulic tracking cutting machine
·The machine is applied to the cutting of the flat bars.
·It do the incessantly shearing to advance the efficiency and the even quality.
h. Fixed length receive table
·The table is designed to 6m.
·Equipped with 6m unload table (which can customized according to customers' specific requirements ).
i. Electrical control system : 1 unit
·Control the working of all the electromotors of the devices (speed control and synchronize).
