Description
Generally, after winding the axial length of the Coil is found to be more than the desired designed length. To achieve the designed length, the Coil needs to be compressed either with the help of a Standard Hydraulic Press or a by means of a specially designed Hydraulic Coil Pressing fixture.
Hydraulic Press – Preferably a Down stroking Four column or H frame Hydraulic Press with Coil loading Trolley is used for such an application. The Press capacity offered varies from 20 Tons – 160 Tons depending on the size of the Coil. The Coil loading Trolley can either be motorised or moved by means of overhead EOT Crane or motorised Winch.
Hydraulic Coil Pressing Fixture – This is a portable fixture which can be taken to the Coil to be pressed, instead of the Coil being transported to the machine as required in case of the above standard Hydraulic Press. This unit consists of three no robust plates which are adequately stiffened to take the maximum pressing force along with 4 no robust studs. A floor mounted independent Hydraulic Power pack with a set of hydraulic hoses with quick couplings completes the full supply.
The Bottom plate acts as the base frame for the multiple Hydraulic Jacks, the Intermediate plate is the Pressing plate which rests on the Hydraulic Jacks. The Top plate acts as the platen against which the Coil is pressed. The Coil is placed between the Pressing plate and the Top plate. The three plates are held together rigidly by the 4 no studs with double nuts. When the Hydraulic Jacks are actuated the Piston rods of the hydraulic cylinders presses the Intermediate Pressing plate which moves up and compressed the Coil against the Fixed Top plate.
We need the customer to furnish the max dia, min/max axial length of the Coil and the max pressing force desired for us to offer suitable machine/fixture.
