Friction Screw Press (Down Stroke)


Grewal Friction Presses are used for forging, stamping, embossing, pressing, sizing, bending, coining, shallow drawing, fire bricks, non-ferrous, hot and cold forging operations etc. These Friction Screw Presses are provided with two friction discs and are balanced and mutually adjusted by secured nuts with a fly-wheel in between them. The body of the press is of steel plate, fabricated with utmost care.


It is of box-type design. All forces including twisting of press are taken care of properly. After welding the body of the Press is glowed free from tension, therefore, the usual danger of breakage is avoided. The screw is made of high quality alloy steel and heat treated to have high hardness and elasticity. Flywheel revolution produces screw revolution and its movement is through bronze nut. Nut is pressed into press frame and is able to withstand greatest stress and to transmit it to the frame.


If desired a safety flywheel and pneumatic control device can be installed at extra cost. The construction of this fly wheel absolutely prevents the dangerous rebounding which can cause spindle breakage and further damages. Common qualities of these presses are good construction. best material. simple and easy handling. The impact velocity approaches that of drop hammer. therefore, longer die life and low foundation cost is achieved. They are used wherever quality and safety are required. A bottom ejector to bring out the work piece is provided at lower part of the bed table.


SPECIAL FEATURES :

  • The cost of machine is low compared to other makes and foundation expense is also minimum.
  • Dies of forging have long life due to high accuracy of the machine.
  • The cost of development , manufacturing and replacement of dies are much low.
  • Great forging accuracy is achieved because of the free stroke.
  • Additional energy can be applied to the same die impression by making several blows.
  • The heat contact time is considerably less than the crank type forging presses and knuckle joint type presses.
  • Cost of repair after years of hard usage is low. A semi skilled worker can operate the machine easily.
