What is the difference between drawing and deep drawing?
Deep drawing is a sheet metal forming process used to fabricate cup-shaped parts; bar drawing is a bulk deformation process used to reduce the diameter of a cylindrical workpart.
What is meant by deep drawing?
Definition. Deep drawing is a sheet metal forming process by which a sheet metal blank is slightly clamped along its perimeter by a blank holder and radially drawn into a forming die by use of a punch.
How do you distinguish between shallow and deep drawing?
Shallow drawing is used to describe the process where the depth of draw is less than the smallest dimension of the opening; otherwise, it is considered deep drawing. Drawing leads to wrinkling and puckering at the edge where the sheet metal is clamped. This is usually removed by a separate trimming operation.
What is the wire drawing process?
The wire-drawing process consists of pointing the rod, threading the pointed end through a die, and attaching the end to a drawing block. The block, made to revolve by an electric motor, pulls the lubricated rod through the die, reducing it in diameter and increasing its length.
What is wire and bar drawing?
Bar or wire drawing is a deformation process in which the work piece in the form of cylindrical bar or rod is pulled through a converging die. The stress applied is tensile. A bar or rod is drawn down in order to reduce its diameter. In general, drawing results in reduction in area of cross-section.
What is the difference between wire and bar drawing?
Difference between wire drawing and rod drawing: Initial stock si e: size: The basic difference between bar drawing and wire drawing is the stock size that is used for forming. Bar drawing is meant for large diameter bar and rod, while wire drawing is meant for small diameter stock.
What is drawing in metal forming?
Drawing is a metalworking process that uses tensile forces to stretch (elongate) metal, glass, or plastic. As the metal is drawn (pulled), it stretches to become thinner, to achieve a desired shape and thickness.
How is metal drawn into wire?
Copper, gold, iron, silver and aluminium are used extensively in flat sheets, foil, and wire because they are highly malleable and ductile. Metals conduct electricity well, a physical property not shared with most other materials.
What is the difference between wire drawing and bar drawing?
A bar or rod is drawn down in order to reduce its diameter. Basic difference between bar drawing and wire drawing is the size of bar stock used for bar drawing is large. Wire is a drawn product having less than 5 mm. For wire drawing smaller diameter bar stock is used.
What are the advantages of wire drawing?
The advantages of wire and rod drawing of other applications are:
- Good surface finishing.
- Adaptability to mass production.
- Close dimensional control.
- Improved dimensional properties.
- Economical benefits.
What is the difference between drawing and extrusion?
Wire is pulled through the die in drawing whereas a billet is pushed through the die in the extrusion. Cables, springs, paper clips etc. are some products manufactured through drawing. Door & window frame, railing and brackets are some products manufactured through extrusion.
