Key Features of our 15 Ton Rotary Friction Welding Machines

  • Spindle driven by AC servo motor
  • Rapid stopping of spindle by regenerative braking which saves energy
  • Welding force provided by servo hydraulic cylinders in closed loop control system
  • Pressure transducer/ load cell and linear scale feedback for load and displacement control
  • On-line plotting of important parameters like axial thrust, spindle speed, loss of length and spindle torque during weld cycle
  • Archival and retrieval of weld data
  • Remote customer support through internet

15T Twin Sliding Head Machine with automatic loading (non-rotating part) and unloading the welded job

This 15 tonne dual sliding head machine is designed for welding end pieces on tubes/pipes to make propeller shafts. End pieces are welded simultaneously with precise orientation, which reduces welding time drastically. The machine consists of a steel fabricated frame on which the LH and RH spindle heads moves on LM guides, by servo hydraulic cylinders. The piston rod of servo hydraulic cylinder which is rigidly mounted on the frame at the left is connected to the left spindle head slide. Another servo hydraulic cylinder at the right is mounted on a slide unit, which can be moved by a pneumatic cylinder. This arrangement helps in accommodating component length variants. The self-centering vices, one fixed and another adjustable are mounted in between LH and RH spindle heads.The machine is equipped with mechanisms for auto loading of non-rotating component (tubes) and unloading of welded components. The machine has a PLC based control system with an industrial PC and software capturing real time weld data.

Specifications
  • Max. forge force : 150kN
  • Max. dia. of tube : 102mm
  • Max. wall thickness : 3mm
  • Max. length of tube : 1500mm

Enables welding at both ends of propeller shafts simultaneously to join end pieces to tube with precise orientation.

6T - Machine With built-in deflash, deflect and auto loading / unloading

Advantages

  • Very short cycle time (few seconds)
  • Ideal for mass production
  • Savings in costly material if bi-metallic component is used (Eg. Drills- HSS/MCS)
  • Low heat -affected zone and hence semi finished components can be welded
  • Low energy consumption
  • No edge preparation, filler material, shielding gas, spattering, fumes and radiation
  • Excellent welding: Joint as strong or stronger than parent material
  • Metals as diverse as Cu to Al, Cu or Al to steel, Titanium to stainless steel etc. can be welded
  • 100% in-process quality check
