1.4 metal forming Flashcards
(27 cards)
What are the 5 cold metal work processes
Pressing/stamping, Spinning, deep drawing, bending, cold rolling
What is the volume of production of pressing/stamping
Large scale mass production
What is the process of stamping/pressing
The sheet metal is pressed between +ve and -ve dies.
What are the 3 hot metal work processes
Hot rolling, open die forging, closed die forging
What is the process of spinning metal
Sheet metal is spun and pressed over a former to produce objects with radial symmetry
What is the volume of production of spinning metal
Batch or mass production
What is the volume of production of deep drawing
Mass or continuous production
What is the process of deep drawing
Sheet metal is forced into a die cavity via a punch. Used to form sinks and cans
What metal forming process could create sinks and cans
Deep drawing
What metal forming process could create a saucepan
spinning
What metal forming process could create car body panels
pressing / stamping
What metal forming process could join car door panels with a “safe” edge
Bending
What is the metal process of bending
Sheet metal is bent between a punch and a die.
What is the process of cold rolling
Billets or plate metal >3mm is made into sheet material <3mm by being fed through rollers
What metal forming process could make filing cabinets
cold rolling
What is the volume of production of bending
One off to large scale batch production
What volume of production is cold rolling
Continuous production
What type of metal forming has a better finish
cold metalwork
What is the process of hot rolling
“Billets” are made into beams, angle, bar, plate etc by being “hot” fed through rollers
What is the volume of production of hot rolling
Continuous production
What metal forming process could be used to make railway tracks
hot rolling
What is the process of open die forging
Metals such as low carbon steel or wrought iron are heated in a forge/furnace and then hammered into shape on an anvil.
What metal forming process could be used to make gates
Open die forging
What is the volume of production of open die forging
One-off or limited batch production
