The perform of 135m finishing mill group
The ending mill group is composed of prime crossed 45° Substantial-velocity wire-rod finishing mills.
The ending mill group is found in high-velocity wire-rod workshop. Through ten device rack the continuous micro-rigidity rolling mill will be transported upstream Æ seventeen ~ Æ 21mm of rolling, rolling turn into Æ 5.5 ~ Æ 16mm completed wire. The doing work velocity of 90m/s is insured. The specification of stop solution is Æ 5.5mm.
Structural qualities of ending mill
Ending mill unit is merged with ten mills, pace rising box, assistance base, arc coupling, watertight slot, water-resistant plate, the protective cover, piping and manual of finishing mill. Mill body is composed of a few 200mills and 7 one hundred fifty mills, frame use top crossed forty five composition kind to accomplish no twisting, no contact axis, minor axis and shock for products, besides, it reduce the center of gravity top, the security enhanced as properly, in the imply time, the total weigh has reduce and it is straightforward to keep. Ten frames are concentrated transmission.
Roll body is composed of roller box, bevel gearbox and spare areas of bevel gearbox.
Roller box and bevel gearbox undertake outdoors combinational instruction, reduce the dimensions of bevel gearbox to lessen the excess weight of finishing mill, lessen the area of mills to make their structure compact. Roller box used cantilever roll loop, there is eccentric locking collar in the box to change roll hole. CZPT bearing and roll shaft are within eccentric locking collar, taper sleeve is employed to fix 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 equipment, geartooth correction is essential. The precision degree of spiral bevel gearbox is six and round bevel gearbox is five to insure the smooth functioning of high pace.
Roller box and bevel gearbox are related by bolts, a component of roller box plug into the bevel gearbox to let two synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are fastened by two locating pin, the roller box with exact same specification can be altered.
The axial pressure 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, since the extremely tiny axial clearance ball by itself, as a result the roll shaft to properly positioned in the axial path, which ensures exact roll rolling precision, which is to ensure the dimensional accuracy of the workpiece.
The roller shaft around the film bearing is developed in the form with taper, so the roller shaft can bear uniform load distribution even it is bend. So the lifetime of roller can be improved.
The adjustment of roll gap is to rotate feed screw with remaining and proper thread and nut. When the two eccentric rotated comparatively, the distance of two rollers transformed with the symmetrical eccentric relative movement of eccentric locking collar, so the location of previous roller line and information can be sustain.
Roller loop is tungsten carbide, it is linked on the cantilever roll shaft, we use the certain hydraulic altering roll gear to exchange roll loop, it is convenient and easy.
