Roller box for 135m/s finishing mill
1. Composition of roller box
Roller box main case, rear side plate, roll shaft, front plate, eccentric locking collar parts, taper sleeve, adjustable feed screw and nut.
2. Technical characteristics
1) ZG315— 570 castings are used for roller box, No. 45 steel plate processed by hardening and tempering methods is used for rear plate and front plate. Main case, rear plate and front plate are processed by high accuracy machining tool( such as NC working center) to ensure the high accuracy requirement for the location of eccentric locking collar and roll shaft.
2) Roll shaft used low carbon alloy steel blank, after roughing, axis need to take ultrasonic flaw detection process to quench. In order to ensure the tooth surface with high hardness, tooth surface need to take carburizing and quenching treatment after semi-finishing. Fine grind of every round and the back of axis insure its accuracy & durableness with taper sleeve and tooth surface. When the produce process of roll shaft finished, we need to take the balance test to insure the rotary accuracy during roll shaft's high speed rotation(6000 Rev / min).
3) Eccentric locking collar adopt medium carbon steel casting, inner diameter and eccentric round are processed by CNC machine center to ensure the eccentric distance and accuracy of inner and outer diameter. Then, the adjustment accuracy of roll gap and the Interchangeability of every eccentric locking collar are ensured.
4)front plate, rear plate and internal parts are mostly made of medium carbon steel and processed by hard chrome plating and anti-corrosion treatment to increase the lifetime.
5)To make sure the roller box can reach the assembly precision requirement, a four-hour idling high-speed trial is conducted upon completion of assembly of roller box and bevel gearbox, a smooth and stable sound and no oil leakage from the joint part are necessary.
