Wire Rod Steel Production Line Finishing Rolling Mill Monoblock Automation Turnkey Project

Wire Rod Steel Production Line Finishing Rolling Mill Monoblock Automation Turnkey Project

The purpose of the equipment
The ending mill group is composed of top crossed 45° large-velocity wire-rod finishing mills.
The ending mill group is found in higher-speed wire-rod workshop. Through 10 unit rack the continuous micro-tension rolling mill will be transported upstream Φ17 ~ Φ21mm of rolling, rolling become Φ5.5 ~ Φ16mm finished wire. The functioning pace of 90m/s is insured. The specification of conclude item is Φ5.5mm. 

Structural characteristics of finishing mill
Finishing mill unit is mixed with ten mills, velocity rising box, assistance foundation, arc coupling, waterproof slot, watertight plate, the protective protect, piping and information of ending mill. Mill frame is composed of a few Φ200mills and seven Φ150 mills, body use leading crossed 45° composition kind to achieve no twisting, no make contact with axis, little axis and shock for products, apart from, it decrease the centre of gravity height, the steadiness improved as well, in the imply time, the complete weigh has decrease and it is simple to preserve. 10 frames are concentrated transmission.
Roll body is composed of roller box, bevel gearbox and spare parts of bevel gearbox.
Roller box and bevel gearbox adopt outdoors combinational instruction, lessen the dimensions of bevel gearbox to decrease the bodyweight of finishing mill, lower the room of mills to make their structure compact. Roller box utilised cantilever roll loop, there is eccentric locking collar in the box to adjust roll gap. CZPT bearing and roll shaft are inside eccentric locking collar , taper sleeve is employed to correct roll loop which is in the finish of roll shaft.
Bevel gearbox is composed of box, transmission box, spiral bevel gear roll and synchronized gears. All gears are hardened grinding gear, geartooth correction is essential. The accuracy stage of spiral bevel gearbox is 6 and spherical bevel gearbox is five to insure the easy doing work of substantial velocity.
Roller box and bevel gearbox are linked by bolts, a component of roller box plug into the bevel gearbox to allow two synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are set by two locating pin, the roller box with exact same specification can be changed.
The axial drive of the roll shaft beared by a pair of thrust ball bearings , this ball bearing mounted on the axial clearance in the absence of the resilient washer, simply because the really modest axial clearance ball alone, consequently the roll shaft to accurately positioned in the axial course, which ensures precise roll rolling precision, which is to ensure the dimensional accuracy of the workpiece.
The roller shaft around the film bearing is designed in the form with taper, so the roller shaft can bear uniform load distribution even it is bend. So the life span of roller can be improved.
The adjustment of roll hole is to rotate feed screw with remaining and correct thread and nut. When the two eccentric rotated fairly, the distance of two rollers changed with the symmetrical eccentric relative motion of eccentric locking collar, so the spot of previous roller line and guidebook can be preserve.
Roller loop is tungsten carbide, it is connected on the cantilever roll shaft, we use the specific hydraulic changing roll gear to substitute roll loop, it is practical and straightforward.
