Volume forging – Extrusion

 Extrusion is a technology which can be used at higher, medium and cold temperatures. Forged material is moved in directions determined by the tool’s construction- extrusion die.  Product is called  extrusion punch.

Extrusion technology: Metals with low forging strength as is aluminum and its alloys can be extruded in one operation. Steel and other metals use more operations.

 It is necessary to treat the material by straitening and cutting before actual extrusion. After that follows surface cleaning and phosphate.  Extrusion die consists of extrusion punch and extrusion die.  Lubricant for extrusion at higher temperatures is glass.  Cold extrusion uses oil.

 Extrusion is divided:  Hot extrusion  Is used for full and hollow profiles with difficult cross sections which cannot be made by rolling. Cold extrusion  Is used for thin walled products, cartridges, tubes, spray cans.  Production is very economic.

 Extrusion is divided according to direction on:  Forward  Backward  Combined  Sidewise  Radial

At forward (direct) extrusion is material moving in the same direction as extrusion punch. It is used for forging pivots, bolts, bushes, products with constant cross section.  Princip dopředného protlačování (1, 3 – die, 2, 4 - punch, a, – punch,  b – wiper, c – die, d – ejector)

 At backwards extrusion, material moves in opposite direction. It is used for manufacturing of hollow extrusions where wall thickness is very thin compared to its diameter.  Princip zpětného protlačování  1, 3 – die, 2, 4 - punch,  a, – punch, b – wiper, c – die,  d - ejector

 Combined (compounded) extrusion  Very stressed, profiled products are made in this manner. Principle of combined extrusion 1, 3 – die, 2, 4 - punch, a, – punch, b – wiper, c – die, d – ejector)

 Side and radial extrusion  At side extrusion is material moving perpendicularly to direction of extrusion punch.  Radial extrusion is a forging where material and tool parts are moving in radial direction to axis of extruded product.  Principle of side (left and middle) and radial extrusion

 Hydrostatic extrusion, semi-finished product is inserted in liquid of very high pressure. By the all- dimensional tension is material ductility increased.

 What kinds of extrusion do you know?  Divide extrusions in accordance to flow direction.  Describe construction of extrusion tool.  What material and method do we use for cold extrusion?  What material and method do we use for hot extrusion?
