PRESS BLANKING LINES

Alcos Precision Press Blanking Lines

ALCOS Press Blanking Lines are specially designed for use in the high demand automotive and fabricating industries, including suppliers of “surface exposed” panels.

Our Press Blanking Lines are capable of processing material up to 72 inches (1828mm) wide and .250 inches (6.35mm) thick from coils weighing up to 80,000 lbs. (36 tonnes) with an outside diameter of up to 100” (2540 mm). As we do with our other lines, we will customize the process configuration to suit your specific requirements.

Our Press Blanking Lines are equipped with electromagnetic or vacuum stackers, high-precision levelers with four, five, and six heights; edge trimming, strip cleaning, drying and oiling systems. ALCOS Press Blanking Lines are computer controlled with diagnosis, quality control, and automatic coil feed. These lines are ideal for carbon steel, exposed and non-exposed materials, stainless steel, pre-painted steel, and aluminum and other metals.

Our Press Blanking Lines Features

Our press blanking lines include many advanced features such as:

Entry Coil Press Station

Designed to enable coil preparation prior to loading on the uncoiler. The system can be fed from either the coil storage turnstile, or the coil storage racks for maximum efficiency. This feature results in reduced downtime normally taken by removing OD coil bands, and in-line entry crop shearing to square the lead end of the strip and remove any damaged or “over gauge” material.

Uncoiling Section

Typical front end include coil storage turnstile, entry coil car, uncoiler with driven hold down roll, and coil peeler. This system provides an easy means of feeding the strip into the line without manually handling the material.

Catenary System

Various catenary systems are available that combine both the entry and exit basket roll units and the strip threading tables. Center collapsing systems with full face rollers, or multi non-marking stud rollers are the preferred choice, but side indexing systems are also available.

In-line Entry Crop Shearing Station

Provided to eliminate any defective or damaged or “over gauge” outer wraps of the coil before threading into the line. This protects the precision leveler from being damaged by this defective material. The system is usually provided with a traversing scrap disposal system, which conveniently removes the scrap away from the line to the main scrap container.

Precision Feed Roll Systems

Our precision feed roll systems provide precise feeding of the strip in exact incremental lengths to the blanking press, based on blank size requirements. Precision Servo control systems are utilized to ensure precise cut length tolerance and diagonal accuracy. Feed Roll surface finish ensures non-marking of the process material surface.

Precision Corrective Levelers

Our precision feed roll systems provide precise feeding of the strip in exact incremental lengths to the blanking press, based on blank size requirements. Precision Servo control systems are utilized to ensure precise cut length tolerance and diagonal accuracy. Feed Roll surface finish ensures non-marking of the process material surface.

The Blanking Press

Rugged straight sided, eccentric gear type with point suspension and is available up to 2000 ton capacity. Straight track rolling bolster die positioning systems and hydraulic in-press clamping systems can be provided to enable rapid die changes. The press can be equipped with tonnage monitors, automatic shut height adjustment, vibration isolators, and light curtain security systems.

Strip Cleaning and Drying Section

Alcos strip cleaning system removes debris and contaminants from the strip, which could otherwise become embedded into the strip by the dies during the press blanking operation. The strip is then dried to remove all possible moisture to prevent corrosion during storage.

Strip Oiling Systems

Oiling systems provide a protective coating to the strip, and also lubricate the strip prior to blanking. Alcos can offer an electrostatic oiler for all grades of liquid and hot-melt lubricants.

The unit can be provided with the ability to be moved off-line by motorized drive while threading tables are pivoted up into position in the line to fill the gap. An oiling system can be added to the line to ensure a precise coating of a clean oil. This system can be either a precision static oiling system, a metered “roll-on” system or a simple light spraying system depending on the demands of the application.

Automatic Blank Stacking Systems – Magnetic or Vacuum

Our magnetic and vacuum stackers are designed for your specific blank dimension range and are offered with two stacking stations for increased stacking capability. This enables continuous operation of the line.

All stack dimension adjustments are motorized and are controlled at the stacker console or by remote control for up-close final adjustment by the operator.

Four discharge stations are fitted with load cells to provide accurate weighing of each stack.

  • Magnetic stackers for steel blanks
  • For both aluminium, stainless steel and carbon steel, the Alcos vacuum stacker is a multi-belt unit with stationary vacuum orifices, providing all the holding power you will need, even for heaviest or most complex blanks with shapes and cut-outs.

ALCOS is the leading manufacturer of coil processing equipment, with slitting lines operating worldwide. ALCOS specializes in ultra-high strength steel and aluminum slitting lines, and their machinery is trusted and proven to be effective.

ALCOS Machinery Inc. has a reputation for producing high-quality products at competitive costs. We strive to meet each client’s needs and can easily ship heavy equipment in North America or overseas  to serve more customers in the global market.
