How does a hydraulics work?

The basic rule of using hydraulic power is Pascal's Principle. Pascal's Principle: pressure exerted on a fluid is distributed equally throughout the fluid. Hydraulicsuses incompresible liquids so the applied pressure from one end (small arrow) is equal to the desired pressure on the other end (big arrow).

What is the punch and die?

Punching is a forming process that uses a punch press to force a tool, called apunch, through the workpiece to create a hole via shearing. ... The punch often passes through the work into a die. A scrap slug from the hole is deposited into thedie in the process.

 

What is simple die?

​

What is nibbling operation?

The nibbling process cuts a contour by producing a series of overlapping slits or notches. This allows for complex shapes to be formed in sheet metal up to 6 mm (0.25 in) thick using simple tools. The nibbler is essentially a small punch and die that reciprocates quickly; around 300–900 times per minute.

 

What is trimming operation?

Trimming is a manufacturing process that is used as a finishing operation for forged parts, in order to remove flash. ... Most often it is desirable to perform thisoperation while the work is still hot for maximum efficiency, therefore it is usually incorporated into the larger production process.

 

What is a blanking press?

Blanking and piercing are shearing processes in which a punch and die are used to modify webs. The tooling and processes are the same between the two, only the terminology is different: in blanking the punched out piece is used and called a blank; in piercing the punched out piece is scrap.

 

What is notching operation?

Notching is a shearing process during which a metal scrap piece is removed from the outside edge of a metal workpiece. Notching is typically a manually operated, low-production process.

 

What is cutting operations?

Blanking is the operation of cutting a flat shape from sheet metal. The product punched out is called the “blank” and the required product of the operation the hole and the metal left behind is discarded as waste. 2: Punching or Piercing: It is acutting operation by which various shaped holes are made in sheet metal.

 

What is the difference between punching and piercing?

Perforating (Punching) is generally used to describe all die-cut holes, regardless of their size or shape. In Techniques in Press working Sheet Metal, Eary and Reeddifferentiate between punching and piercing by emphasizing the fact that a slug is produced in punching operations but not in piercing work.

 

What is the deep drawing process?

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. It is thus a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part exceeds its diameter.

 

What is the drawing process?

Drawing is a metalworking process which uses tensile forces to stretch metal or glass. As the metal is drawn (pulled), it stretches thinner, into a desired shape and thickness. Drawing is classified in two types: sheet metal drawing and wire, bar, and tube drawing.

 

What is hubbing process?

Hubbing is a metalworking process that is used to make dies. It is a cold-workingprocess, which means that it occurs well below the melting temperature of the metal being worked.

 

What is a rolling process?

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

 

What is coining operation?

Coining is a closed die forging process, in which pressure is applied on the surface of the forging in order to obtain closer tolerances, smoother surfaces and eliminate draft. Closed die forging is a process in which forging is done by placing the work piece between two shaped dies.

 

What is cold drawing process?

The Cold Drawing Process for Steel Bars and Wire. Raw Stock: Hot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. ... The drawing machine pulls or draws the remaining unreduced section of the bar or coil through the die.

 

What is the difference between embossing and coining?

The difference between coining and embossing is that the same design is created on both sides of the work piece in embossing (one side depressed and the other raised ), whereas in coining operation, a different design is created on each side of work piece.

 

What is bending operation?

Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.

What is the K factor in sheet metal?

SOLIDWORKS sheet metal tools are relatively straight forward, but may not be clearly understood. In sheet metal, there is a powerful bend constant known as theK-Factor. It ultimately allows you to estimate the amount of stretch without knowing what type of material you are bending.

 

What is the bend allowance?

The bend allowance and bend deduction are two measures that relate the bentlength of a piece of sheet metal to the flat length. The bend allowance describes the length of the neutral axis between the bend lines, or in other words, the arc length of the bend.

 

What is meant by bend allowance?

By definition, the bend allowance is the arc length of the bend as measured along the neutral axis of the material. By definition, the bend deduction is the difference between the bend allowance and twice the outside setback.

 

What is the bending radius of a cable?

Bend radius, which is measured to the inside curvature, is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater is the material flexibility (as the radius of curvature decreases, the curvature increases).

 

What is the difference between K factor and Y factor?

The formula according to which developed length is calculated is: L = ( 0.5 * Pi / R +Y-Factor * T ) Angle / 90. The Y-Factor = ( Pi / 2 ) * K-Factor. The K-Factor is a physical value defining the ratio of distance from the inner side of the bend to the neutral layer and sheet metal thickness
