Plate Straightening Machines

Product Code : 05

Product Specification

Our clients can avail from us quality range of plate straightening machines that is easy to operate and maintain. Each straightening roll is crowned to compensate for deflection, which results into small diameter of the rolls, smallest possible distance between the rolls, with increased range of operation and best straightening results. Each roll is mounted in high-grade bronze bearings that results in low drive power, low side pressure and low maintenance costs for the bearings. Extremely efficient and reliable, these machines are available in various capacities ranging from 6 mm to 100 mm sizes in spans of 1500 mm upwards.

The main components of the machines are fabricated machine-body with the roll system and the driving gears. Made from welded steel plate, the body housings are rigid and resistant to torsion even under peak loads in continuous service. The upper part of the body comprises the drive system for the vertical adjustment, the upper straightening rolls and the two auxiliary rolls. Guides built into the upper and lower part of the body adequately absorb all transverse forces.

Roll System

The roll system consists of 5 or 4 or 3 upper and 4 or 3 or 2 lower straightening rolls and the two auxiliary rolls
The auxiliary rolls, one of them arranged at the entry side and the other at the exit side in the top part of the machine body, can be vertically adjusted under load independent of each other
They are well supported (Against backlash) even when thin plates requiring correspondingly low straightening force are being processed

Drive

A reversible induction motor affects the main drive
The transmission to the spur gears is through a heavy coupling
All high-speed shafts including the spur gears are mounted in antifriction bearings
The upper roll system is brought into working position through reversible induction motors

Operation

The machine can be operated and supervised and the straightening process can be watched closely from a control desk containing all controls
The distance between the upper edge of the lower roll and the lower edge of the upper roll is indicated on the dials mounted at the non-driving side of the machine
The squirrel cage reversing motors similarly mounted on the drive side of the machine effect the adjustment of the two auxiliary rolls
The degree of adjustment is indicated on two dials at the feed side of the machine
Limit switches limit the adjusting ranges of the upper roll system and of the auxiliary rolls

Maintenance

The machine requires little maintenance
All lubrication points that are not connected to the oil circulating lubrication system of the main drive or to the oil plunge lubrication for the adjusting gears of the upper roll system are supplied by an automatic central force feed lubrication system
All machine elements requiring occasional cleaning or readjusting are easily accessible
