Forging process & type of forging process

 WHAT IS FORGING ?

           Forging is metal forming process to giving required shape & size to red hot metal by applied   impact force

          forging is process where metal and alloy first heated above its cretical tempreture and after that  compressive force is applied to get final shape by plastic deformation

Types of forging :-

  1. smith and hand forging 
  2. drop forging
  3. press forging 
  4. machine forging , upset forging   
SMITH FORGING :- 
          In this type of forging smith is used to to get shaped & hammer on red hot metal manually Hence  its also called as Hand forging.

                                
  • DROP FORGING :-
          In the drop forging process the red hot metal and alloy placed on die and after that first raised   hammer and drop forcefully on red hot metal to get required shape



  • PRESS FORGING :-
          press forging opration carried out by continuous slow squeezing action.  the squeezing action is created by or produced by mechanical press or hydraulic press  d out by continuous slow squeezing action.  the squeezing action is created by or produced by mechanical press or hydraulic press  
          
There are two types of press forging 
  1. open die forging :-                                                                                                                              In the open die forging both upper die and lower die are flat and horizontal the process may done by hand or power hammers. the heavy falling weight of the hammer is called ram and rigid support called anvil block
  2. closed die forging:-                                                                                                                              the workpiece is kept between upper die and lower die . in this process mechanical hammers a, air and steam hammers are used .

  • UPSET FORGING  :-
                                             Upset forging involves upsetting operation. its also called as machine forging. upsetting machine are called upsetters are generally horizontal acting. the job gripped in the fixed half die and pressure acting from free end causing it to be upset

MATERIALS , CLASSIFICATION OF MATERIALS .

 WHAT IS MATERIALS ?      Materials is a substance or, mixture of a more substance that is use for as input in manufacturing process and can be used for making or doing something . New materials are produced from raw materials . Mild steel, tor steel, cast iron, aluminium, copper, concrete, bricks, tiles, stones, timbers, glass are commonly used materials for engineering purpose.  Important properties of materials are mechanical, thermal, chemical, electrical, magnetic, physical, etc. practically in engineering generally materials are used for structural purpose, machine parts or electrical & electronics devices CLASSIFICATION OF MATERIALS  Elastic material :  A material is said to be perfectly elastic when the deformation produced under the action of external loads and regains its original size and shape after remove external deforming load. for example:- rubber are the best example of elastic material Plastic material:- A materials is said to be plastic material when the deforma

 ENTHALPY WHAT IS ENTHALPY ? Enthalpy is a thermodynamic property of system , it is the sum of the internal energy added to the product of the pressure and volume of the system  H = E +(PV) where , H = enthalpy              E = internal energy               P = pressure              V = volume It reflects the capacity to do no mechanical and capacity to release heat . Enthalpy is denoted by H & the specific enthalpy is denoted by h . Common units are used to express enthalpy are Joule's , colorie , BTU ( british thermal unit) Enthalpy is constant in throatling process Eenthalpy of system measurement is possible to measure the difference between in enthalpy between one state and another IMPORTANCE OF ENTHALPY It is used to calculate the head of reaction of a chemical process measuring the change in enthalpy , to determine wheather a reaction was endothermic ( absorbed heat positive change in enthalpy ) OR exothermic ( released heat , negative change in enthalpy) change in enthal
