Presses (metalworking) Specifications

Help with Presses (metalworking) specifications:

Press Type


	Press Type
	Your choices are...
	Clinching Machine		Clinching machines use a cold forming process to fasten sheet metal components together. During the clinching process, a punch forces the two layers of sheet metal into a die, creating a permanent connection. Clinching machines are an economical alternative to riveting and welding operations. Clinching is commonly used in the HVAC, automotive, manufacturing and housing industries.
	Die Cutting Machine		Die cutting presses are used in the manual conversion of web or sheet materials such as woven cloth, non-woven textiles, and rubber sheeting. Clicker presses and rotary die cutters are designed for the die cutting of web or sheet materials.
	Forming and Bending Machine		Forming machines are designed to form or bend metal sheets or plates.
	Hydroforming Press		Hydroforming presses are designed to process metal source-material sheets, plates or tubes. The resulting parts are typically of higher quality than those produced from traditional stamping methods. Compared to stamping, finished parts from a hydroforming process often offer better strength, geometry, surface finish, aerodynamics, and other desired performance characteristics. Low-drag and visually-pleasing automobile hoods are one example of a hydroform-pressed component.
	Punch Press		Punch presses are used for punching, blanking, piercing, nibbling, tab forming, stamping, press forming, embossing and slug cutting.
	Shop Press		Shop presses are designed for general-purpose job shop operations. They include arbor presses, ironworkers, metal shears, and press brakes.
	Sheet Metal Equipment		Sheet metal equipment is designed to fabricate components from sheet metal. These industrial presses are capable of stamping, blanking, punching, bending, spinning, stretching, or nibbling.
	Stamping Press		Stamping presses fabricate components from sheet metal using blanking, piercing or punching, forming, bending and drawing.
	Wire Forming		Wire forming presses are designed or suitable for wire forming or wire bending operations.
	Specialty		Other unlisted, specialized, or proprietary presses or forming machine tools.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Hot Press		Thermal presses or machines are suitable for elevated temperature operations such as hot stamping, hot forming, or diffusion bonding of metals. The metal or material is heated to a plastic state, allowing a level of deformation that would cause cracking or excessive residual stress in a cold forming operation.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Press / Operation Type


	Operation
	Your choices are...
	Bending		Presses can produce simple bends of at least 90 degrees or more.
	Blanking		Presses are suitable for blanking operations. Blanking is the cutting of a part from sheet stock.
	Broaching		Presses are designed to cut gears or splines by forcing a broach or multi-toothed cutter along the internal or external surface of a part.
	Cut-off / Shearing		Presses are designed for cutting-off or shearing stock of various thicknesses.
	Deep Drawing		Presses can perform deep drawing, stretching, and other press-forming operations.
	Fine Blanking		Presses are suitable for fine blanking operations. Fine blanking cuts a part from sheet stock, while maintaining much higher tolerances than conventional blanking. A stiffener and high-precision machining are required.
	Extrusion Forming		Presses form parts such as tin paste tubes through extrusion or back-extrusion operations.
	Marking / Coining		Presses can perform marking or coining operations. Marking or coining results in a local change in cross-section.
	Nibbling		Presses perform nibbling operations. Nibbling is a punch-cutting process where irregularly-shaped holes are formed via a series of rapid punch hits or strokes across the part. Nibbling can also refer to presses or shearing machines that cut contours in a sheet with a series of small or scissors-like cuts.
	Piercing / Hole Punching		Presses can perform piercing, perforating, or hole-punching operations.
	Press Forming / Embossing		Presses can perform stamping, embossing, or other shallow press-forming operations. These presses or machines may also be capable of simple bending or forming operations such as tab or louver forming. Embossing is used to form beads, stiffen ribs, or locate features.
	Side Punching / Notching		Presses can side-punch, notch, or pierce a tube or component. Notching may also refer to the removal of corners or outer edges from a sheet or part.
	Straightening / Flattening		Presses can straighten or flatten sheet metal, plates, or other stock.
	Tube Sheet Forming		Presses can form tube sheets for boiler or heat exchanger applications.
	Other		Other unlisted, specialized, or proprietary press operations for forming or cutting materials.

Force / Pressure Specifications Pressure is applicable to isostatic presses.


	Capacity / Operating Force:		The operating press load required to cut or form a part or rivet assembly during production. The rated capacity of a press is the ton pressure, which the slide or ram will safely exert at the bottom of the stroke while working within the range of the press. In a mechanical press, the capacity is determined by the bending capacity of the main shaft (crank, toggle, or eccentric shaft).
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Pressure		Pressure is the hydraulic force per unit area exerted by the industrial press upon the piece being worked.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Speed & Stroke Specifications

	Features
	Your choices are...
	Double / Triple Acting		Presses have two-or-more slides for multiple, independent, parallel movements. Double-acting presses are used in draw forming processes because they provide a way to hold down or clamp the rim of the sheet. There are two types: mechanical and hydraulic. With mechanical double-acting presses, one slide is operated by crankshaft; the outer or blank holder slide, which dwells during the drawing process, is usually operated by a toggle mechanism or cams. Hydraulic double-acting presses have multiple cylinders to drive the different slides. Triple-acting presses typically have a lower slide mechanism with an upward or opposing motion.
	Multi-Station (Rotary Turret)		Multi-station presses use rotary tooling or turrets, progressive dies, transfer systems, or other multi-station die sets. Rotary turret punch presses are automatic machines that index the material and select the required tool from the rotary tool holding device or turret, usually by computer control. Depending on the program selected, turret punch presses are used for piercing, blanking and forming workpieces.
	Multi-Tool		Multi-tool systems consist of multiple tool turrets within a single turret. They provide automatic indexing.
	Coil / Web Feeder		Coil feeders and web feeders are integral or optional sub-systems that are used to feed sheet-metal coil stock, or cut strips and other web materials.
	Integral Cut-Off / Shear		Machines provide the integral shearing or cut-off of sheet or web materials, or excess scrap material. Examples include a flying shear on a rolling mill machine.
	Integral Laser Cutter		Presses feature an integral laser-cutting system to provide additional fabrication capabilities.
	Laboratory		Equipment is designed for laboratory applications such as process parameter studies, material development, or sample preparation.
	Load / Press Monitor		Presses have sensors and monitoring systems for detecting the load and thickness of compacted materials.
	Manufacturing Cell (Loader / Stacker)		Presses are complete manufacturing cells, production lines, or turnkey systems with material handlers, degreasing units, or other sub-systems for fabricating parts from coils, metal sheets, or web materials. Alternatively, these press or stamping systems may have loading, stacking, or destacking features for handling sheets, parts, or materials.
	Other		Other unlisted, specialized, or proprietary features.
