Stamping dies are used with a press ,  as opposed to. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology. Continuous-feed laser cutting may displace the analogous die-based process in the automotive industry,  among others. Blanking and piercing are two die cutting operations, and bending is an example of a die forming operation.
Forming operations work by deforming materials like sheet metal or plastic using force compression , tension , or both and rely on the material's mechanical properties. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers called blister packs for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. The workpiece may pass through several stages using different tools or operations to obtain the final form.
In the case of an automotive component, there will usually be a shearing operation after the main forming is done. The main components of a die set including press mounting are as follows. Note that because nomenclature varies between sources, alternate names are in parenthesis:. Steel-rule die, also known as cookie cutter dies, are used for cutting sheet metal and softer materials, such as plastics, wood, cork , felt , fabrics , and paperboard. The cutting surface of the die is the edge of hardened steel strips, known as steel rule.
These steel rules are usually located using saw or laser-cut grooves in plywood. The mating die can be a flat piece of hardwood or steel, a male shape that matches the workpiece profile, or it can have a matching groove that allows the rule to nest into. Rubber strips are wedged in with the steel rule to act as the stripper plate; the rubber compresses on the down-stroke and on the up-stroke it pushes the workpiece out of the die.
The main advantage of steel-rule dies is the low cost to make them, as compared to solid dies; however, they are not as robust as solid dies, so they are usually only used for short production runs.
In the broadest sense, a rotary die is a cylindrical shaped die that may be used in any manufacturing field. However, it most commonly refers to cylindrical shaped dies used to process soft materials, such as paper or cardboard. Two rules are used, cutting and creasing rules.
Rotary dies are faster than flat dies. The term also refers to dies used in the roll forming process. Wire -making dies have a hole through the middle of them.
A wire or rod of steel , copper , other metals, or alloy enters into one side and is lubricated and reduced in size. The leading tip of the wire is usually pointed in the process. The tip of the wire is then guided into the die and rolled onto a block on the opposite side. The block provides the power to pull the wire through the die.
The die is divided into several different sections. First is an entrance angle that guides the wire into the die. Next is the approach angle, which brings the wire to the nib, which facilitates the reduction.
Next is the bearing and the back relief. Lubrication is added at the entrance angle. The lube can be in powdered soap form. If the lubricant is soap, the friction of the drawing of wire heats the soap to liquid form and coats the wire. The wire should never actually come in contact with the die.
A thin coat of lubricant should prevent the metal to metal contact. For pulling a substantial rod down to a fine wire a series of several dies is used to obtain progressive reduction of diameter in stages. Standard wire gauges used to refer to the number of dies through which the wire had been pulled. Thus, a higher-numbered wire gauge meant a thinner wire. Typical telephone wires were gauge, while main power cables might be 3- or 4-gauge.

Perhaps the only in-tended function of these facilities is to replace perishable details,screws, and dowels, and do minor detail repairs such as sharpen-ing punches and die sections. The only machine tools in such afacility may be a small drill press, lathe, and surface grinder. However, even though the plant is not equipped to perform any-thing other than running maintenance, it can and should have a. A good die maintenanceprogram is a system that maintains dies so that unexpected break-downs are avoided, all repair costs are accurately accounted for,and die repair cost, per part produced, is minimized. If a systematic die maintenance programa means of trackingthe condition of dies to assure cost-effective, timely maintenanceis not in place, achieving a fully functional system will take time.
It is a press tool capable of cutting the metal, bending it, drawing its shape into considerable depths, embossing, coining, finishing the edges.
