All Metals Installs Cassette Leveler Multi-Blanking Line

Turret Head™ Slitter set-ups are accomplished while the line is running, eliminating setup downtime. The Turret Head™ is simply withdrawn from the line when producing full width sheets.

Precision Electronic Servo-Feed: All Metals' Multi-Blanking Line employs a reliable high-cyclic rate precision AC servo to feed and meter strip to precise length tolerances. The Servo-Feed draws the leveled strip from a free-loop and feeds the strip through the Shear to a pre-set length. Part length is precisely metered by an electronic encoder while a microprocessor automatically establishes ideal acceleration/deceleration rates. Length and batch count are easily entered into the digital operating system. Servo Feeds compare favorably to "reciprocating mechanical hitch feeds" in productivity and reliability. Grabbing, releasing, sliding backwards, and re-grabbing consumes the majority of a reciprocating hitch feed's cycle time. By comparison a Servo-Feed drives one-way and has few moving parts that require repair and replacement. The Servo-Feed's quick rotary operation, low acceleration/deceleration shock load, few moving parts with an absence of chains, screws, clamps, and related mechanical parts results in consistent close-tolerance accuracy, low operating cost, and "bullet-proof" reliability.

In addition to the Servo-Feed's quick cycle rate, it employs an instantaneous "pull-back" sequence that pulls the strip away from the shear blade during the shear cycle. The pull-back sequence is an important feature for preventing shear blade scuffing.

Hi-Performance Variable Speed Shear: A massive top driven variable speed DC motor driven Shear is utilized for part cut-off. The high-performance Shear is capable of producing pattern length sheets in a 60-stroke/minute "clutch-brake" mode, and shorter multi-blank parts in an 80+ stroke/minute non-stop "continuous-stroke" mode. Synchronized with the Servo-Feed, the continuous non-stop shear cycle offers unrivaled productivity performance. The DC motor driven crankshaft runs non-stop, synchronized with the Servo-Feed cycle when the Shear runs in the "continuous-stroke" mode. The pull-back and feed sequence begins as soon as the upper shear blade severs the strip on its down stroke.

The continuous-stroke mode allows the strip to be fed forward while the Shear ram is traveling up. The feed sequence continues well past Shear top dead center and stops when the shear blade approaches the strip on the down stroke. The continuous-stroke Servo Feed-DC Shear cycle expands the feed forward window and results in a production rate much higher than a conventional start-stop feed-shear mode.

Massive Hi-Performance, Continuous-Stroke, DC Bow-Tie Shear Offers Unrivaled Production Performance.

The Variable-Speed Bow-Tie Shear operates in an 80-SPM continuous-stroke mode while cutting five multi-blank strips.

Programmable Multi-Blank Stacker: The Multi-Blank Stacker features full automatic set-up via microprocessor controlled AC servo motors. The automatically positioned multi-blank blank dividers produce "solid-block" straight-sided single sheet and multi-blank packs. A pushbutton initiated part "reject" system kicks-out sheets and blanks that fail All Metals' quality standards.

Precise tolerance panel flat parts, solid-block sheet packs, hi-performance, plus Bullet-Proof Reliability made All Metals' choice of a Braner/Loopco Cassette Leveler-Servo Feed-DC Bow-Tie Shear Cut-to-Length/Multi-Blanking Line a "no-brainer".
