51、e welder with automatic centering.- To ensure continuous strip unwinding to the line under regulated tension.DescriptionThe pay off reel mainly includes :- an expansible mandrel,- a gear box, - a mobile frame supporting the gear box and drive unit,- a stationary frame.- a stripper plateThe mandrel i

52、s made of the following elements :- a sleeve in special iron GGG 70- 4 segments in nitrided steel (superficial hardness 500 to 600 HV5, on a depth of 0,3 mm minimum)- Wear plates in 42 Cr Mo 4, nitrided- Each segment includes 5 wedges- Mandrel shaft made of 30 Cr Ni Mo 4 (90/105 kg/mm)- Central expa

53、nsion rod connected to a rotating expansion cylinder- Linear transducer mounted on the mandrel, for purpose of precise measure of actual inner coil diameter- 2 conical bearings are mounted at mandrel end for the mandrel nose - Grease lubrication, by hand pump without any dismounting.The gear box is

54、manufactured with a horizontal joint and includes 2 stages of gears.The frame is made of welded and machined steel.Gears are of helical type, made of steel treated at 100kg/mm.Gearings and bearings calculated for a service life of 50.000 hours at maximum speed and load. The bearings of mandrel shaft

55、 are selected in order to have a zero play. The mobile frame is of machined welded steel. It moves on the static frame through a hydraulic cylinder.The static frame is of welded steel design, anchored to foundation.A system of machined ways (one flat, one V-shaped) and counter slides provided with b

56、ronze wear plates.The stripper plate includes a pushing plate actuated by hydraulic cylinder. In an out movement guided by 2 rods moving in bushings mounted on the housing of the gearbox.Still stand disc brake between motor and gearbox actuated by electro-pneumatic brake.372. ENTRY SHEARFunctionTo c

57、ut off the unconforming head and tail of the coils.Shear actuation controlled by PLC of entry section, based on: - overthickness information coming from level 2- entry thickness gauges if implemented in the future. Description“Start-stop” upcut shear of guillotine type, cuts strip when stopped by me

58、ans of a pinch roll pneumatically pressed and a spring loaded clamping device. -The upper blade is fixed; the lower blade is movable and actuated by hydraulic cylinder, articulated rod and double levers in V.A special pin is provided to avoid any shearing operation during the maintenance periods.Bla

59、des are in special steel x 100CrMoV51; each has four cutting edges for low maintenance and long life. The moveable blade has a slight slope, and the fixed one is straight.The moving holder slides in machined ways on the shear side frame. These ways are lined with replacement brass wear plates.-The r

60、igid frame is of fabricated welded design. Guides and supports are mounted so as to avoid hurting of the ends during feeding and contact with blades while running.-Just before the shear blades, a low pinch roll unit is mounted, actuated by 2 pneumatic cylinders with rack and pinion system for synchr

61、onisation. Top roll is fixed and driven by hydraulic motor, the bottom roll is moveable and idle. The purpose of this pinch roll is to clamp the strip during cutting sequence, to thread the front end of strip into the shear, and to discharge the last crop end. A photocell in combination with a pulse generator signal, ensures that the latter is long enough (to avoid the falling of small residual pieces in the machine). Note: The shear item 168, at bottom pass line, includes a second pinch roll unit, identical to the pinch roll here above, and mounted on the frame of the shear, at
