Metal forming operations

  1. 1. Sheet Metal Forming Processes Manufacturing Processes
  2. 2. Outline Introduction Shearing Blanking Bending Deep Drawing Stamping Dies Progressive Dies Transfer Dies Spinning
  3. 3. Sheet Metal Working Products: automotive fenders washers stamped parts channels
  4. 4. Examples of Stamped Parts
  5. 5. Examples of Stamped Parts
  6. 6. Examples of Stamped Parts This part was made from several stamped parts plus a nut, which were stamped again to seal them together
  7. 7. Examples of Stamped Parts This part was made from a sheet that was stamped, bent, and welded into a tube, plus a separate stamped end piece
  8. 8. Examples of Stamped Parts
  9. 9. Shearing A sheet-metal cutting operation along a straight line between two cutting edges
  10. 10. Shearing of Metal Between Cutting Edges
  11. 11. Shearing of Metal Between Cutting Edges 1/3 of material is cut and 2/3 of material fractures
  12. 12. Blanking Involves cutting the sheet metal along a closed outline
  13. 13. Piercing and Blanking Shearing operations in which the shear blades are closed, curved lines along the edges of the punch and die In blanking, the piece punched out is the workpiece; in piercing, the remaining strip is the workpiece
  14. 14. Punch and Die
  15. 15. Bending
  16. 16. Bending
  17. 17. Bending Springback
  18. 18. Deep Drawing A sheet metal forming operation used to make hollow-shaped parts
  19. 19. Deep Drawing
  20. 20. Redrawing Additional drawing steps (redrawing) may be required if the shape change of the material is too severe
  21. 21. Example of a Drawn Part
  22. 22. Example of a Deep Drawing Press
  23. 23. Stamping Die
  24. 24. Stamping Die
  25. 25. Progressive Die Performs multiple operations at different stations with every press stroke
  26. 26. Progressive Die
  27. 27. Example of Progressively Stamped Parts This sheet has been stamped by a progressive die, showing the series of operations from right to left
  28. 28. Progressive Die
  29. 29. Progressive Die
  30. 30. Progressive Die
  31. 31. Progressive Die
  32. 32. Progressive Die
  33. 33. Progressive Die
  34. 34. Examples of Stamping Machines
  35. 35. Progressive Die in Stamping Press
  36. 36. Progressive Die
  37. 37. Material Coils
  38. 38. Material Feed
  39. 39. Material Feed
  40. 40. Transfer Line
  41. 41. Transfer Line
  42. 42. Transfer Line
  43. 43. Transfer Line
  44. 44. Transfer Press
  45. 45. Transfer Press
  46. 46. Transfer Die
  47. 47. Spinning Uses a spinning mandrel and a roller to form sheet metal into a radially symmetrical part
  48. 48. Spinning Courtesy Koch Metal Spinning
  49. 49. Tube Spinning Uses a spinning mandrel and a roller to reduce the wall thickness and increase the length of a tube
  50. 50. Summary Blanking, bending, and deep drawing are capable of producing an immense variety of thin metal parts Progressive dies can produce parts at high production rates by performing multiple operations simultaneously
