  2. Forming Mills

  3. Forming Mills Most important forming mills: Rolling mills Presses Bending machines

  4. Forming Mills • Rolling mill • Two-rolled, three-rolled, universal • Using: • Sheet manufacturing • Profile bars(I,U, rails) • Wires

  5. Forming Mills • Presses • Presses are divided according to purpose: • Forming • Forging • According to drive: • Mechanical presses • Hydraulic presses

  6. Forming Mills Hydraulic press Usage Big forgings from ingots Deep drawing Hot extrusion Stamping Cold extrusion Usually verticalTwo pillars Four pillars (more often)Small presses: Single plunge Bigger presses: Three plunge with ability to engage individual plungers-> increase of pressure

  7. Forming Mills • Mechanical press • Usage: • Drop forging • Deep drawing • Shearing • Stamping • Cold extrusion • Bending

  8. Forming Mills • Forging press- spring • power hammer • Usage: • Forging die • Free forging • Propulsion: From electromotor through friction transmission to flywheelFrom crankshaft by mechanical levers to a ram Ram speed (ram blow) is increased due to upper two arm lever is made from pack of spring-leaves

  9. Forming Mills • Drawing press

  10. Forming Mills • Compressed air hammer • Usage: • Free forging • Consists of: a) StandWorking cylinderRam made as a plunger is moved inside -> is driven by compressed airCompressor’s cylinderb) Anvil block

  11. Forming Mills • Eccentric press

  12. Forming Mills • Press brakeBlanking press

  13. Forming Mills • Forging rolls • Usage: • Precision forgings • Pre-forging of products with variable profiles • Not working continuously, but with jumps Cylinders are placed on stands turning against each other, calibrated only on one half of circumference

  14. Forming Mills • Bending machine
