Swaging Machines or Tube End Forming Machine

The range of tube end forming machines made available by us of principally two designs :

Push type systems:

• In these systems there is no rotary movement of die
• Job is pushed into die with help of hydraulic cylinder mounted at end of punch slide

Rotary cum push type:

• Carbide die is clamped into die head
• It continuously gives rise to rotary movement with help of DC motors
• Punch slide force component into die with help of hydraulic cylinder provided at other end of machine

With the Tube end forming or swagging machines purely operating on cold process, these consume less power, thus making them highly suitable for industries for mass production of

• Swaged parts
• Swaged component

Swaging machine - Working

• The machine works by using two as well as four split dies that separate and close up to several times a minute
• The action is achieved by mounting dies into machine's spindle that is rotated by motor
• Spindle is mounted inside cage containing rollers
• With rollers larger than cage, spindle spins the dies and is pushed out to ride on cage
• As dies cross over the rollers, it pushes dies together because of their larger size

Rotary swaging process

• It's a cold working process
• Its used to reduce diameter, produce taper or add point to round work piece
• It can also impart internal shapes in hollow work pieces through use of mandrel
• Variation of rotary swager in creeping spindle swaging machine where both the spindle and cage revolve in opposite directions, prevents production of fins between dies where material being swaged grows up the gap between dies
