Drawn out: length increases, cross-section decreases 2. Upset: Length decreases, cross-section increases 3. Squeezed in closed compression dies: produces multidirectional flow. Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting.
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer ) or a die . Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working ), warm forging, or hot forging (a type of hot ...
Some of example of forming processes are: Forging; Extrusion; Rolling; Sheet metal working; Rotary swaging; Thread rolling; Explosive forming; Electromagnetic forming; Plastic extrusion; Die forming (plastics)#Process; Food extrusion#Process
Forge welding (FOW), also called fire welding, is a solid-state welding process [1] that joins two pieces of metal by heating them to a high temperature and then hammering them together. [2] It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the ...
Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting , forging , extrusion , powder metallurgy , and blanking . As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
The patent [4] for this product can be found on the list of google patents. There, it lists a clear description of each part integral to the function and process used to create squeeze-cast metals. For example, it describes what temperatures and pressures are required, what function each step serves, and how it relates to the whole process.
The process combines the advantages of casting and forging. The process is named after the fluid property thixotropy, which is the phenomenon that allows this process to work. Thixotropic fluids flow when sheared, but thicken when standing. [3] The potential for this type of process was first recognized in the early 1970s. [3]
