The operate of 135m ending mill group
The finishing mill group is composed of best crossed 45° Higher-speed wire-rod finishing mills.
The ending mill team is situated in high-speed wire-rod workshop. Via 10 device rack the steady micro-tension rolling mill will be transported upstream D17 ~ D 21mm of rolling, rolling grow to be D five.five ~ D16mm completed wire. The functioning pace of 90m/s is insured. The specification of end solution is D5.5mm.
Structural traits of finishing mill
Finishing mill unit is merged with ten mills, pace escalating box, assist foundation, arc coupling, water-resistant slot, water-proof plate, the protective cover, piping and manual of ending mill. Mill frame is composed of three 200mills and 7 one hundred fifty mills, body use top crossed forty five composition sort to attain no twisting, no get in touch with axis, little axis and shock for equipment, in addition to, it lessen the heart of gravity top, the security enhanced as well, in the imply time, the whole weigh has decrease and it is straightforward to keep. Ten frames are concentrated transmission.
Roll frame is composed of roller box, bevel gearbox and spare parts of bevel gearbox.
Roller box and bevel gearbox undertake outside combinational instruction, lower the dimensions of bevel gearbox to lower the weight of ending mill, decrease the place of mills to make their framework compact. Roller box used cantilever roll loop, there is eccentric locking collar in the box to adjust roll hole. CZPT bearing and roll shaft are inside of eccentric locking collar, taper sleeve is used to fix roll loop which is in the stop of roll shaft.
Bevel gearbox is composed of box, transmission box, spiral bevel equipment roll and synchronized gears. All gears are hardened grinding equipment, geartooth correction is required. The precision stage of spiral bevel gearbox is six and round bevel gearbox is five to insure the sleek operating of substantial velocity.
Roller box and bevel gearbox are linked by bolts, a element of roller box plug into the bevel gearbox to enable two synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are mounted by two locating pin, the roller box with identical specification can be changed.
The axial force 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, because the extremely tiny axial clearance ball alone, for that reason the roll shaft to properly positioned in the axial route, which ensures exact roll rolling precision, which is to ensure the dimensional precision of the workpiece.
The roller shaft in close proximity to the film bearing is developed in the sort with taper, so the roller shaft can bear uniform load distribution even it is bend. So the life time of roller can be enhanced.
The adjustment of roll hole is to rotate feed screw with left and correct thread and nut. When the two eccentric rotated comparatively, the distance of two rollers changed with the symmetrical eccentric relative movement of eccentric locking collar, so the place of former roller line and manual can be maintain.
Roller loop is tungsten carbide, it is connected on the cantilever roll shaft, we use the specific hydraulic modifying roll gear to exchange roll loop, it is handy and easy.
