METAL GATHERING MACHINE

Torsion Bars:

• Comprises of metal gathering (upto 150 Kva) and forging in horizontal hydraulic press upto 150 tons and can handle basic diameter upto 40 mm alongwith clamping and upsetting dies/punches

• Kejetherm metal gathering machine is fully hydraulically operated with resistance heater.

• Metal gathering operation consists of heating the part of the job and pushing the remaining cold material of the job into hot zone till the required metal gathering takes place.

• By employing metal gathering many of the well known technical limitations and disadvantages of mechanical upsetting can be overcomed
• Simultaneous heating and forming in one machine.
• Almost unlimited gather in one operation. The mechanical upsetting limitation of about 3 x dia. No longer applies. The modern engine valve has an upset length of up to 20 x dia. And lengths of upto 40 x dia. Are commonly electro-upset.
• No longitudinal flash is formed such as is unavoidable in a split-die mechanical upsettler.
• No waste of heating energy or material. Outside of the upset volume can be precisely controlled to allow subsequent, "flashless" forging in closed dies.
• Always ready for instant use, no warm up period.
• Energy efficient, about 0.35 - 0.40 kwh / kg.
• Minimal scaling because of simultaneous heating and gathering. Improved die life in subsequent forging operations.
• No environmental pollution by emission of heat, fume or exhaust gas.
• Free upsets can be finished forged without re-heating and so save time and energy.
• Consistent heating temperature through the use of thyristor control.
• Optimal grainflow and fault free surface. The unheated bar length remains unchanged

• Typical electro-upset parts rear axle shaft
• Drive shaft or torsion bar
• Engine valve
• Pinion gear
• Tie-rod end
• Selector fork

• Tmg-V(D) -150 Kva Heavy Duty Vertically Down Holdings As Jobs Are Heavy For Auto Components And Bolts For Ship.
