285/320/340/385 prefinishing mill block
4 cantilever mills.Horizontal mill(two stands),vertical loop(three),vertical mill(two stands) and safety hood.
Arrangemeng and transmission mode:H-V-H-V;DC motor drives separately.

1. The effect of Vertical loop:
Wire-rod has the problem of the dynamic tension fluctuation caused by interference when it is in the process of rolling, so it lead to the fluctuation of the dimension of the rolling element, vertical loop can eliminate part of the tension fluctuation to make sure the precision of the equipments.
2. The structure of Vertical loop:
Vertical loop is composed of sets of roll(it is pushed by cylinder), back-up roll and loop groove. The sets of roll used to form cover. Side-wall is used to support the element to form the loop. Loop adopt the central pole mount, which is easy to turn on and adjust the mill guide and guard
The diameter of sets of roll cylinder is Φ 160mm; Distance is 200mm.
The working altitude of loop is 100mm higher than the rolling centre line.
The highest altitude of loop is 400mm higher than the rolling centre line.
3, Lubrication and pneumatic:
The transmission parts of loop adopt glycerol manual lubrication.
The air used in loop and rear brakes is unified offered by workshop, the pressure to compressed air is around0.4~0.6Mpa.
(1)the effect of Side loop: Wire-rod has the problem of the dynamic tension fluctuation caused by interference when it is in the process of rolling, so it lead to the fluctuation of the dimension of the rolling element, side loop can eliminate part of the tension fluctuation to make sure the precision of the equipments.
(2)the structure of side loop: Side loop is composed by cylinder, sets of roll, loop platform, turning roll and loop scanner. Cylinder push the sets of roll. Sets of roll is mainly combined by the roll on the rocker. When the sets of roll is in the location of retraction, roll fully withdraw the rolling line, the tip of roller can directly get into the finishing mill through loop platform. When the sets of roll turn to the extended position, it forward to the rolling line and push the rolling element to loop platform, then the loop is formed.
The diameter of sets of roll cylinder is Φ 130mm; Distance is 254mm.
The working altitude of loop is 300mm.
The highest altitude of loop is 700mm.
(3)Lubrication and pneumatic:
The transmission parts of loop adapt glycerol manual lubrication.
The air used in loop and rear brakes is unified offered by workshop, the pressure to compressed air is around0.4~0.6Mpa.

Structural characteristics of finishing mill:
Finishing mill unit is combined with ten mills, speed increasing box, support base, arc coupling, waterproof slot, waterproof plate, the protective cover, piping and guide of finishing mill. Mill frame is composed of three Æ200mills and seven Æ150 mills, frame use top crossed 45° composition form to achieve no twisting, no contact axis, little axis and shock for equipment, besides, it decrease the center of gravity height, the stability increased as well, in the mean time, the total weigh has decrease and it is easy to maintain. 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 adopt outside combinational instruction, decrease the size of bevel gearbox to decrease the weight of finishing mill, decrease the space of mills to make their structure compact. Roller box used cantilever roll loop, there is eccentric locking collar in the box to adjust roll gap. Film bearing and roll shaft are inside eccentric locking collar , taper sleeve is used to fix roll loop which is in the end 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 needed. The accuracy level of spiral bevel gearbox is six and round bevel gearbox is five to insure the smooth working of high speed.
Roller box and bevel gearbox are connected by bolts, a part of roller box plug into the bevel gearbox to let two synchronized gears in bevel gearbox meshed. Roller box and bevel gearbox are fixed by two locating pin, the roller box with same 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 very small axial clearance ball itself, therefore the roll shaft to accurately positioned in the axial direction, which ensures accurate roll rolling precision, which is to ensure the dimensional accuracy of the workpiece.
The roller shaft near 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 lifetime of roller can be improved.
The adjustment of roll gap is to rotate feed screw with left and right thread and nut. When the two eccentric rotated relatively, the distance of two rollers changed with the symmetrical eccentric relative movement of eccentric locking collar, so the location of former roller line and guide can be maintain.

80m/90m/135m finishing mill and speed increasing box
Heavy duty finishing mill for 45° top cross untwisted high-speed wire rod:ϕ230×10structure,speed increasing box,large base,water baffle and waterproof groove,buffer box,protective cover,coupling,and finishing mill are equipped with pipes.
The upstream ϕ17~ϕ21mm rolled piece is rolled into ϕ5.5~ϕ16mm finished product.

Wire discharger:Safety guard is the cylinder structure and the spinning head is installded in it .Its incline design is for the security. Top half of safty guard can been opened by the air cylinder for changing the spinning pipe but its must been closed at regular work. It should been processed static balancing test for all of the equipments with rotation dabber.Then we can increase or decrease the weight of them on basis of testting. After static balancing test it should been processed dynamic balance test which measure datas are :testting rotate speed : 1900r/min, dynamic balance quality : G2.5.There are two test points in the front and back bearing cap when the wire discharger is assembled you could test vibration data on the two points.And the test vibration masure data is 5mm/s.

It is the vertical cantilener structure and the center line slopes down ten degrees. It consists of spinning pipe which is installed in the rotation dabber and gearing.There is one DC adjustable-speed motor that could drive the rotation dabber through a pair of bevel gear wheel.Spinning pipe can spin regular wire coil on the basis of setting revolving speed .
Wire discharger rotation dabber consists of spinning head and hollow shaft.Spinning head is usede to fixation spinning pipe and hollow shaft.And the hollow shaft would been drived by bevel gear in the driving box.There is a pipe among the internal of bevel gear.And there is water-cooling drivepipe between the pipe and hollow shaft .Water-cooling drivepipe is used for cooling the pipe and it will protected the bearings of the hollow shaft to keep away from high temperature of rolled piece.
Wire discharger drive gear box used welding structure. The gear and bearings used thin oil central lubrication process.
