Scrap Cutter and Chopper

THE MECHANICAL SCRAP CHOPPER.

The P/A Mechanical Scrap Chopper has a unique helical-ground blade which chops a wide variety of materials from .004″ paper to 3/16″ CRS without adjustment. Once installed, any number of stock thicknesses and widths can be fed into the chopper without any additional set-up time. With a P/A Scrap Chopper mounted on your machine, you eliminate the need for air blow-offs, sheet metal chutes, conveyors and rakes used by operators to get the scrap out of the tool area and into containers. Providing one chopper per press can save the cost of designing and building guillotine choppers for every die. Rugged cast iron construction with few moving parts assures maintenance-free production. The Reel-Type scissor action reduces off centre loading by chopping a width of only 14 times the maximum material thickness at one time regardless of total stock width.

THE AIR SCRAP CHOPPER.

The P/A Air Scrap Chopper is designed to operate where mechanical actuation is not possible or desirable. Using the same principle as our Ram Driven Scrap Chopper, this pneumatically powered chopper is designed to shear scrap material from .004″ to .074″ thick mild steel. Set-up is simple having no mechanical connections, allowing for a stand-alone operation if desired. The operation is pneumatic using an electrical signal from the press, limit switch, or rotary cam. A powerful, double acting air cylinder provides controlled chopping while integral dampeners absorb snap through shock. The helically ground upper blade, made of high chrome steel, shears any kind of material. A four-way solenoid valve controls the sequencing. This valve can be synchronized with any machine by a limit switch, proximity sensor, or programmable rotary limit switch. If a timing relay counter is used, the chopper can be set to cycle when desired with any multiple of press cycle or a timing cycle unrelated to the parent device is possible for longer scrap pieces or extremely high-speed operations.

THE PNEUMATIC STOCK CUTTER.

This pneumatically powered scrap chopper is designed to shear scrap material from .004″ to .074″ thick mild steel. A powerful, double acting air cylinder provides controlled chopping while integral dampeners absorb snap through shock. The helically ground upper blade, made of high chrome tool steel, shears any kind of material. A four-way solenoid valve controls the sequencing and can be synchronized with any machine by a limit switch, proximity sensor or programmable rotary limit switch. If a timing relay or counter is used, every other press stroke operation is possible for longer scrap pieces or extremely high speed operations.
