CNC end-forming machine TUBE-FORM ELE

Fully electric CNC combined tube end operations

TUBE-FORM ELE is a fully electric CNC range of machine for combined tube end operations on tube O.D. 50mm max. ALL machine movements are electrically programmed and driven (including power control and modulation of the ram tool) assuring tight accuracy and absolute consistency.

Its modular design allows to organise the most suitable process flow according to the required tool and final job.

Main features:

  • Up to 6 ram stations
  • Full combination of ram and rotary tool operations
  • Available machining & forming operations: de-burring - beading - expanding - facing - threading - rolling - friction welding - machining - cutting - milling

All operations are fully CNC programmable (up to 8 controlled axis). This avoids manual operations with substantial savings in cycle times and loading and unloading operations with increased benefits in quality and work repetition.

Load / Unload

SOLUTIONS

Thanks to the wide range of loading devices customers can choose the best solution for their needs. Following are the main features of our handling systems:

  • Special pneumatic loader with double clamp for the simultaneous load/unload. The loading cycle is contemporary to the machine cycle.
  • High-range automatic loader
  • Loading device for the sequential loading of both tube ends in automatic
  • Robots, manipulators, vibrators for the loading of bushes
  • Integration in manufacturing cells with bending stations connected by means of robots
  • Automatic collecting systems on wheels

Accuracy and repeatability of the end-forming process

Thanks to the "all electric", you can install the independent rotary mandrel (RGL31) for rolling processes with the following results:

  • Execution of complex profiles
  • Enhanced repeatability and accuracy (guaranteed tolerance ± 0,05mm)
  • Reduced changeover time (-50%)
  • Tool change and parameter reset in less than 5 minutes

TUBE_FORM-ELE_eng_ted

Process aimed to produce Al 3003 water collectors (18x1 mm) for the automotive industry and consisting of the following working steps:

PROCESSES
  • start from coil
  • straightening
  • end-forming of end n. 1
  • swarfless cut without burr
  • end-forming of end n. 2
  • 100% in-line control of the machined tube ends (both sides)
  • automatic unload for the following working step
  • CNC bending with 3 different stacks
  • piece unload according to piece type

The advantages of this solution and process configuration are the following:

  • cycle time is reduced by 2/3 for each piece,
  • production quality remains the same over three working shifts, independent from operator
  • only one operator required
  • no scraps, and 100% in-line production control
  • * just in time production without intermediate material storage
