What are the types of drawing process?

Drawing process can be divided into following three types.

• Wire Drawing: A wire is a circular, small diameter flexible rod.
• Rod Drawing: Rod drawing is similar process like wire drawing except it is rigid and has larger diameter compare to wire.
• Tube Drawing:
• Working Process:

What is drawing process in mechanical engineering?

Introduction to Drawing  Drawing is a cold working process in which the work piece is pulled through a tapered hole in a die so as to reduce its diameter.  Accurate Dimensions ,specified cross-section and clean and excellent quality of surface to work.  Appreciably increases strength and hardness of metal.

What is deep drawing in manufacturing process?

The term—deep drawing— refers specifically to the depth of the item that is created, which is equal to or greater than its diameter. The deep drawing process involves a single metal blank and forming it into a 3D round, square, or rectangular shape called a case or enclosure.

What is the process of drawing down steel?

Metal drawing is a manufacturing process that forms metal work stock by reducing its cross section. This is accomplished by forcing the work through a mold, (die), of smaller cross sectional area than the work. This process is very similar to metal extrusion, the difference being in the application of force.

What is wire drawing in manufacturing?

Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s). Although similar in process, drawing is different from extrusion, because in drawing the wire is pulled, rather than pushed, through the die.

What is drawing simple?

Drawing is a way of making a picture. Drawings are created by making lines on a surface. Long lines make up the shapes and small lines make the textures. They draw on paper or on other surfaces on which the marks show up.

What is drawing and deep drawing?

Deep drawing is a sheet metal forming process in which a sheet metal blank is radially drawn into a forming die by the mechanical action of a punch. The process is considered “deep” drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the part through a series of dies.

What is cupping and deep drawing?

Deep drawing (cupping) is a manucfacturing process used to create deep, seamless och round shapes from sheet metal. When deep drawing, a tool (called a plug) punches sheet metal into a die. The sheet metal takes the same shape as the tools, commonly a round shape with a radius and depth.

What is a machine drawing?

(d) Machine Drawing — Machine drawing may be defined as the representation of a machine component or machine by lines according to certain set rules. A machine drawing generally gives all the external and internal details of the machine component from which it can be manufactured.

What is tube drawing process?

Tube drawing is a process to size a tube by shrinking a large diameter tube into a smaller one, by drawing the tube through a die. There are five types of tube drawing: tube sinking, mandrel drawing, stationary mandrel, moving mandrel, and floating mandrel.

What is wire drawing in valves?

Wire drawing occurs when the valve disc and seat position operate for extended periods of time close to the shut-off point of the valve, and the water flow erodes or scores a pathway in the seating material that remains when the valve closes tight to the shut-off position.
