GENERAL DESCRIPTION

 

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 operator’s 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.

 

ENTRY GUIDE

 

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.

SLITTER

 

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 operator’s 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 operator’s 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.

FLYING SHEAR

 

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.

DIE ACCELERATOR

 

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.

 

DRIVE

 

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.

LUBRICATION

 

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.
