CUT TO LENGTH SECTION
NO OF WORK ROLLS: 9
WORK ROLLS DIA: 3 Ό
SHEAR: HYDRAULIC ACTUATOR
The Steelpro section is the main component of the whole line and performs the functions of strip guiding, trimming and/or slitting, leveling and cutting the strip to predetermined length on a continuous basis. It consists of and entry unit, slitter, Flattener, Flying shear, shear accelerating mechanism, DC drive and controls
With the exception of electrical controls which are housed in a separate operators console, all components parts of the Steelpro section are mounted on a weld steel base with provision for anchoring to floor. The pinch rolls of the entry Unit, slitter arbors, flattener rolls and the shear accelerator are powered by a single DC motor through gear reducers and universal drive shafts. This results in a compact and close-coupled arrangement of Steelpro sub-units and provides speed synchronism between all working rolls and the flying shear. The speed of the line is infinitely variable up to the maximum of 100 Ft/min.
Comprised of two lower and one upper driven rolls of tubular construction followed by a set of driven solid pinch rolls. All rolls are carried in anti-friction rollers bearings. Rotating entry strip guides are adjustable mounted in the first two lower rolls permitting manual setting for different strip widths. Each roll carries two guides collars in two take up bearing blocks and is vertically adjustable to provide a limited amount of roll penetration into the strip to ensure a limited curvature correcting effect.
The pinch rolls pull the material through the entry unit into the slitting section. Both rolls are made of alloy steel. They are hardened and ground. The upper roll is lowered and raised by a diaphragm type pneumatic cylinder and manually controlled valve.
This unit is capable of performing a maximum of four cuts in material gauges up to .125 or 4 cuts in heavier gauges. It is intended to slit the incoming material into a maximum of three strands. This in gauges up to .125 It may be used for taking two slitting cuts and two edge trimming cuts, while in gauges above .075
Either two slitting cuts or two edge trimming cuts are possible. In either case 9 outside diameter slitter knives should be used.
The slitter drive side arbor support is stationary, while operators side arbor support is removable for tooling changes. Lower arbor is fixed; upper arbor adjustable vertically by independent jacking screws to facilitate knife set u or removal. Both arbors are carried in tapered roller bearings at the drive side and needle roller bearings at the operators side.
The slitter arbors are driven by universal drive shafts from the pinion stand. A set of slitting knifes and adjustable knife holders are included.
FOUR (4) HIGH FLATTENER
This Unit is capable of imparting commercial flatness to steel strip in the range from approximately .01 to .125 thick. In this range the material is worked plastically to sufficient depth to achieve satisfactory flatness. It is less effective in this respect when steel strip of thickness bellow .020 is being processed.
The unit consists of nine (9) flattener work rolls, a set of pinch rolls at the entry end and a combination pinch and measuring roll at the exit end.
The flattener section is consisting of four over five roll design. The last top roll being provided to correct the curl imparted to the strip by the last bottom rolls. All Rolls are alloy steel, hardened and ground. They are supported by needle roller bearings. All lower flattening rolls and pinch rolls are fixed; upper rolls are banked adjustable in the vertical plane by a screw jack arrangement with inter-connecting shafts to permit synchronized roll penetration into the material to be achieved from the operator side of the machine.
The upper pinch roll at the entry end and the measuring roll located at the flattener exit end are raised or lowered by air cylinders actuated by manual valves.
All rolls (with the exception of the measuring roll) are powered by universal drive shaft and a pinion stand.
This unit will be an hydraulic operator down cut shear. The shear will move with the material and cut from a predetermined electronic signal. The housing will be welded steel construction mounted in anti-friction cam rolls on hardened rails.
The upper knife holder will move on four posts with bronze sliders. And will be actuated by hydraulic cylinders, equalized by a rack and pinion arrangement.
The knives will be high carbon, high chrome steel with 4 cutting edges.
The upper knife is fixed and the lower knife bolster is adjustable for clearance by jackscrews.
The die accelerator consists of two racks driven by pinions through an air clutch to the main drive. The shear is returned by an air cylinder and held at O by absorbers.
The Steelpro Unit is powered by a DC motor coupled to a worm gear reducer which in turn is closed to a pinion stand with twelve output shafts. Universal drive shafts are employed to supply power to all working rolls. An additional universal drive shaft supplied power to the shear accelerator.
Worm gear reducers are splash lubricated. A circulating oil system provides lubrication for gears and bearings of the pinion stand. Roll bearings and other points are manually lubricated through individual grease fittings.
ELECTRICAL POWER AND AIR SUPPLY - SUPPLIED BY CUSTOMER
HYDRAULIC POWER from central system
NOTE: The hydraulic system is designed for the capacity of the described line. Increasing the capacity is need if other hydraulic actuators or functions are added.
Item 6. RUNOUT CONVEYOR
Item 7. PACK LIFT TABLE
Conveyor rolls will be tubular steel rolls, turning in anti-friction bearings on fixed shaft.
Shafts are mounted on welded steel frame. Rolls are driven roll-to-roll through a chain and sprocket arrangement by a hydraulic motor. The table is raised and lowered by a manual valve.
Hydraulic power from central hydraulic system.
Item 8. SHEET STACKER (See above photo)
Two full width conveyor rolls, provide support for the blanks as they transfer into the stack in chambers. Separator curtains are provided. Each curtain is a flat steel plate mounted in screw clamps at each end. The stop is manually adjusted.
FRAME MOUNTING The frame is mounted in V grooved wheels, running on track at 90 deg. to the line to allow clearance for pack removal.
Item 9. STORAGE CONVEYOR
