Pipe-bending machines

Pipe-bending machines

Pipe-bending machines are used for the manufacture of bent pipes (e.g. for furniture, pipelines etc.) in series. The pipe is clamped and bent on a bending head of appropriate radius. The process as such is free of cutting shocks.

 
 

Requirements of components/ systems:

  • Series-compatible solutions (modular principle)
  • Low noise emission
  • Decentralized closed-loop control electronics
  • Bus communication (comprehensive diagnostics)
  • High control quality of guide rail in-feed
  • High positioning accuracy at bending head
  • Exact motion co-ordination within the space
  • Interpolation between hydraulic and electric axes
  • Incorporation of simulation software
