Die Back Plate:This plate prevents the hardened Die inserts penetrating into bottom plate. Guide Pillar & Guide Bush : Used for alignment between top and bottom halves of the press tools. Bottom plate:It is used to hold bottom half of the press tool with press slide. Stripper plate: it is used to strip off the component from punches.
A spotface or spot face is a machined feature in which a certain region of the workpiece (a spot) is faced, providing a smooth, flat, accurately located surface.
A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]
Die set (plates). [5] Placement can be inverted depending on the operation, such as use of a knock-out: [6] Die block – the lower (bottom) half of the die set. Machined to conform to the desired shape of the workpiece being formed or cut. Punch plate – the upper (top) half of the die set. Holds and supports the different punches in place.
Spot welding (or resistance spot welding [1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
Orifice plate showing vena contracta. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice [1] but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.
The zone plate's focusing ability is an extension of the Arago spot phenomenon caused by diffraction from an opaque disc. [2] A zone plate consists of a set of concentric rings, known as Fresnel zones, which alternate between being opaque and transparent. Light hitting the zone plate will diffract around the opaque zones.
