5. Brief introduction of the line
1). Simplified de-coiler
◆It adopts the de-coiling device to expand and shrink manually which could expand fromφ480mm to φ520mm .
◆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.
◆ Loading capacity: 5T.
2). 7 roller-straightener
◆It will be equipped with press arm to press the coil
◆It is divided into 2 pinch rollers and 5 leveling rollers.
◆ 2 pinch rollers can eliminate part of the bur after the shearing, while the 5 leveling rollers pre-leveling the plate to feed the flat bar more easily.
◆ The diameter of the rollers isφ125mm (Material: GCr15. Hardness: 62-64). It shares the 45KW motor with 2-roller pinch and press device and both sides of the rollers are adopted the roll bearing to support.
3). Chamfering and extrusion machine
◆ It adopts the 10 stand roller (Material: GCr15. Hardness: 56-58) which are divided into 5 groups , these rollers are used to press and squeeze each side to do the chamfering and edging.
◆This part can make the sharp edge to blunt so that forming the round sides of the flat bars.
4).2 roller-pinch and press device
It is driven by the 45KW motor which is shared with the flat surface straightener, with the reason driven ratio to achieve synchronize.
◆It is equipped with gear distribution box(Material: 45#. Hardness: 50-54).
◆The diameter of the two rollers are 187.5mm(Material: GCr15. Hardness: 62-64), they are used to pinch and press and polish the surface.
5). Longitudinal straightener
◆7 stand rollers (Material: GCr15. Hardness: 56-58) to straighten the flat bars longitudinal bending.
6).Flat surface straightener
◆It is equipped with 45KW frequency conversion control motor with decelerator.
◆It is composed of 2 pinch rollers and 9 leveling rollers(Material: GCr15. Hardness: 62-64).
◆The motor change to frequency conversion control which is cheaper and with a perfect speed and length
7). 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.
8). Fixed length receive table
◆The table is designed to 6m
9). Hydraulic system◆Include the hydraulic cylinders on the devices, oil pipes, hydraulic valve and
so on to ensure the whole line’s hydraulic action.
◆ It is equipped with 7.5KW motor.
10). Electrical control system
◆Control the working of all the electromotors of the devices (speed control and synchronize)
