Roller box of Φ285 finishing millComposition of roller boxRoller
case, front lateral plate ,front panel, upper and lower
eccentric locking collar, upper and lower roll shaft, taper sleeve,
slip loop and cooling spout.Technical characteristics1, the main
case use manganese steel as welding workpiece to guarantee the
required intensity of big impact and heavy loads. In order to
ensure the stability required of the precision of the produce of
the case, the case need to take aging treatment after welding to
eliminate internal stress. Every equipped holes in the case and the
surface should use the fine tool to produce to make sure the case
accuracy and interchangeability.2, Upper and lower roll shaft use
the low carbon alloy steel as the welding blank, after roughing,
workpiece 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 tooth surface to
insure the high accuracy. After finishing the produce of roll,
the balance test is needed to make sure the spinning accuracy when
roll shaft is working in the high speed (2500r/min) condition. 3,
Upper and lower eccentric locking collar use ZG310-570 welding
steel workpiece, inner diameter and outer eccentric use finishing
machine tool to ensure the inner and outer eccentric distance and
machining precision. So the interchangeability of eccentric locking
collar and adjustment precision of roll gap is guaranteed.4, Front
lateral plate and front panel use carbon steel to take
quenching and tempering treatment, the yielding of workpiece adopt
high precision machining tool. Upper and lower surface need to
grind to ensure the interchangeability and equipped accuracy
required. The bluing and hard chrome plating on the surface of
workpiece ensure the durableness of workpiece.5, Roller box and
transmission box used embedded structure to increase the total
intensity and stability. After finished the installation, at least
2hours no-load high speed test is needed. The work sound
should be uniform, smooth, no-impact noise. The joint surface has
no leakage after the installation of roll shaft and transmission
box. Checking whether the assemble accuracy of roller box can
reach the design
requirement.Before sale: design the suitable machine based on the specific demandsMedium sale:1.Based on customer's demand to offer moderate quotation project
