A typical compound fine blanking press includes a hardened die punch (male), the hardened blanking die (female), and a guide plate of similar shape/size to the blanking die. The guide plate is the first applied to the material, impinging the material with a sharp protrusion or stinger around the perimeter of the die opening. Next, a counter ...
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [2]
Shearing – punching, stamping, scissoring, blanking; Abrasive material removal – grinding, lapping, polishing, water-jet; Heat – flame cutting, plasma cutting, laser cutting; Electrochemical – etching, electrical discharge machining (EDM), electrochemical machining (ECM) Every method has its limitations in accuracy, cost, and effect on ...
An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long.
Shearing is a kind of mechanical finish in which the appearance of the fabric is enhanced by cutting the loops or raised surface to a uniform and even height. The machine may have a spiral blade similar to a reel lawn mower. [1] [2] A shearing machine can cut the loop or the pile to a desired level. [3]
Most punch presses are mechanically operated, but simple punches are often hand-powered. Major components of this mechanical press are the frame, motor, ram, die posts, bolster, and bed. The punch is mounted into the ram, and the die is mounted to the bolster plate. The scrap material drops through as the workpiece is advanced for the next hole.
Many machine manufacturers offer their own custom nesting software designed to offer ease of use and take full advantage of the features of their specific machines. If a fabricator operates machines from more than one vendor, they may prefer to use an off-the-shelf nesting software package from a third-party vendor. They then have the potential ...
