Transcript of "Forging processes"

  1. 1. -Presented by P. Deepak Kumar FT-3, Roll No.-10
  2. 2. Smith Forging • Smith forging is also called flat die and open die forging. It includes the broad field of forging work produced between flat faced dies and possibly supplemented by stock tooling. • The final shape of the forging depends on the skill of the smith for size and shape. • Smith forging produces work pieces of lesser accuracy as compared to impression or closed die forging. • Tooling is simple, inexpensive and allows the production of a large variety of shapes.
  3. 3. Smith Forging
  4. 4. Open Die Forging
  5. 5. Impression Die Forging • Impression die forging makes use of cavities in specially prepared dies to produce forged shapes in large quantities. • Impression die forging is mainly of 3 types: • Drop forging • Press forging • Machine forging
  6. 6. Impression Die Forging
  7. 7. Closed Die Forging • Closed die drop forging sometimes referred to as impression die forging comprises of a die on the anvil which resembles a mould, the ram which falls and strikes the top of the work piece can also be equipped with a die. The metal work piece is heated and placed on the lower die while the ram falls down forcing the metal to fill the contours of the die blocks.
  8. 8. Closed Die Forging
  9. 9. Hand Forging • This forging is done by hammering the piece of metal when it is heated to the proper temperature on an anvil. While hammering the heated metal is generally held with suitable tongs. • Hand forging is employed only to shape small number of light forgings mainly in repair shop.
  10. 10. Hand Forging
  11. 11. Power Forging • Large machine parts cannot be forged by hand, since the comparatively light blow of a hand or sledge hammer is unable to produce a great degree of deformation in the metal being forged.
  12. 12. Power Forging
  13. 13. Power Hammer • Power hammers are mechanical forging hammers that use a non-muscular power source to raise the hammer preparatory to striking, and accelerate it onto the work being hammered. Also called "Open Die Power Forging Hammers."

  15. 15. Types of Power Hammers
  16. 16. Helve Hammer
  17. 17. Trip Hammer
  18. 18. Lever spring Hammer
  19. 19. Pneumatic Hammer
  20. 20. Steam Hammer/ Air Hammer
  21. 21. Press Forging • Press forging is done in presses. The action is relatively slow squeezing instead of delivering heavy blows and penetrates deeply because it gives the metal time to flow. • Press forgings are shaped at each impression with a single smooth stroke and they stick to the die impression more rigidly.
