The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the described two roller horizontal mills of the utility model.
Referring to Fig. 1, the described two roller horizontal mills of the utility model comprise rolling mill base, rolling-mill housing, are installed in upper and lower two rolls 3,2 and the roll seam guiding mechanism that are arranged in parallel in the rolling-mill housing.For realizing adjustment of two roll seams and roll gap automatic centering, four angles of said rolling mill base 5 upper ends respectively are provided with a column, and said rolling-mill housing is floating type frame 11, between four columns; Upper end at said column also is provided with the roll gap centering body; The bearing block 1 of said bottom roll is arranged on the inwall of floating type frame sill.Like this, under the effect of roll seam guiding mechanism, the bearing block 4 of topping roll can carry out vertically moving on the window inwall of floating type frame 11 on the one hand; Under the effect of roll gap centering body, floating type frame 11 can carry out along the column of rolling mill base 5 vertically moving on the other hand.
For improving the effect that floating type frame vertically moves, respectively be provided with blade fin on said column and the wall that floating type frame 11 matches, this blade fin can move floating type frame 11 vertical in the rolling mill base upper pillar stand and lead and spacing.
Said roll seam guiding mechanism is the mechanical type transmission mechanism that is arranged on the fluid pressure type transmission mechanism with displacement transducer 7 on said floating type frame 11 entablatures or has encoder.Said roll gap centering body is to be arranged on the movable top cover 6 of said column upper end and the mechanical type transmission mechanism that has the fluid pressure type transmission mechanism of displacement transducer 7 on this top cover 6 or have encoder is installed.
The described two roller horizontal mills of the utility model can be two roller horizontal mills with Contiuum type bearing block, also can be two roller horizontal mills with split type bearing block.So-called " Contiuum type bearing block " is the roll to the short roller body, and because of the bearing block at its two ends connects together, that is: a pair roller only has two bearing blocks 4,1, like Fig. 1,2,4,5,7; So-called " split type bearing block " is the roll to the long body of roll, and because of the bearing block at its two ends is provided with separately, that is: a pair roller has four bearing blocks 14,17 and 15,16, lays respectively at the transmission side and the fore side of two rolls, like Fig. 3,6,8.
For two roller horizontal mills with Contiuum type bearing block; Referring to Fig. 1,2; The fluid pressure type transmission mechanism of said roll seam guiding mechanism; Comprise: a hydraulic cylinder for reduction system 9, this hydraulic cylinder for reduction system 9 is installed on the entablature of said floating type frame 11, and the end face of its piston rod contacts with topping roll bearing block 4.
For two roller horizontal mills with split type bearing block; Referring to Fig. 3; The fluid pressure type transmission mechanism of said roll seam guiding mechanism; Comprise: two hydraulic cylinder for reduction system 9, these two hydraulic cylinder for reduction system 9 are installed on the entablature of floating type frame 11 equally, and the end face of its piston rod contacts with topping roll bearing block 15,16 respectively.
No matter the bearing block of the described two roller horizontal mills of the utility model still is split type bearing block for the Contiuum type bearing block, and the fluid pressure type transmission mechanism of said roll gap centering body comprises one or two centering hydraulic cylinder 8 that is installed on the said top cover 6; When rolling, the shift motion of said centering hydraulic cylinder 8 is 1/2 of hydraulic cylinder for reduction system 9 shift motions, and the moving direction of the moving direction of said centering hydraulic cylinder 8 and said hydraulic cylinder for reduction system 9 is opposite.When being a centering hydraulic cylinder 8, piston rod passes top cover 6 and is connected in series with the cylinder body of said hydraulic cylinder for reduction system 9 through Connection Block 13, and is as shown in Figure 2, and perhaps piston rod passes top cover 6 and is connected with the entablature of said floating type frame 11, and is as shown in Figure 3; When being two centering hydraulic cylinders 8, piston rod passes top cover 6 and is connected with the entablature of floating type frame 11, and is as shown in Figure 1.
Like this, when adjustment two roll seams, control hydraulic cylinder for reduction system 9 makes topping roll 3 move with respect to bottom roll 2, and meanwhile, control centering hydraulic cylinder 8 makes floating type frame 11 carry two rolls 2,3 and moves with respect to rolling mill base together.The shift motion of setting hydraulic cylinder for reduction system 9 is 2 times of centering hydraulic cylinder 8 shift motions; That is: through displacement transducer 7 electric interlocks; Control hydraulic cylinder for reduction system 9 piston rod amount of movements are 2 times of centering hydraulic cylinder 8 piston rod amount of movements, and moving direction to make topping roll 3 on the contrary are floating type frame 11 and two rolls 2,3 twices of amount of movement together with respect to the amount of movement of bottom roll 2.
More than, bottom roll 3,2 gaps adjustment is reduced to example: suppose: upper and lower roll 3, the total backlash adjustment amount between 2 :-Δ h; The operation principle of above-mentioned adjustment two roll seams is formulated as follows; Wherein: the direction with the X-Y reference axis is a standard; With "+" expression, when the moving direction of roll or floating type frame is opposite with the reference axis Y direction, represent when the moving direction of roll or floating type frame is identical with the reference axis Y direction with "-".
If: topping roll 3 moves down adjustment :-Δ h
Floating type frame 11 and two rolls 2,3 adjustment that moves up together :+1/2 Δ h
Then: topping roll 3 actual moves down adjustment :-Δ h+1/2 Δ h=-1/2 Δ h
The actual adjustment that moves up of bottom roll 2 :+1/2 Δ h
Upper and lower roll 3, total backlash adjustment amount: (Δ h+1/2 Δ h)-(+1/2 Δ h) between 2=-Δ h
Floating type frame 11 actual shift motions :+1/2 Δ h
Can learn from the aforementioned calculation result: when topping roll moves down adjustment-1/2 Δ h; The bottom roll 2 adjustment+1/2 Δ h that correspondingly moves up; Floating type frame also correspondingly moves+1/2 Δ h simultaneously, thereby relatively moves two rolls 3,2, has realized that not only the gap of topping roll 3 and bottom roll 2 reduces adjustment; And the roll gap of two rolls 3,2 can be regulated the invariant position at maintenance roll gap center in automatic centering.And upper and lower roll 3, the total backlash adjustment amount is-Δ h between 2, that is: two roll seam adjustment amounts also are that the adjustment amount of depressing of rolled piece is-Δ h.
Otherwise, if upper and lower roll 3,2 gaps are adjusted into when increasing, that is: hypothesis: upper and lower roll 3, the total backlash adjustment amount between 2 :+Δ h; Synergy because of roll balance mechanism 10 pretension counter-forces; Topping roll bearing block 4 abuts against the piston rod end of hydraulic cylinder for reduction system 9 all the time, and equally through displacement transducer 7 electric interlocks, control hydraulic cylinder for reduction system 9 piston rod amount of movements are 2 times of centering hydraulic cylinder 8 piston rod amount of movements; And moving direction is opposite; When making topping roll move up adjustment-1/2 Δ h, bottom roll 2 correspondingly moves down adjustment+1/2 Δ h, and floating type frame also correspondingly moves down adjustment+1/2 Δ h simultaneously; Thereby move two rolls 3,2; Not only realized the gap adjustment of topping roll 3 with bottom roll 2, and the roll gap automatic centering of two rolls 3,2 adjusting, still can keep the invariant position at roll gap center.Its operation principle is identical, is not going to repeat.
When adjusting the initial position of two roll seams; At first control the centering hydraulic cylinder 8 of roll gap centering body; Move floating type frame 11, make the roll gap center adjustment to desired location, and then through displacement transducer 7 electric interlocks; The hydraulic cylinder for reduction system 9 of control roll seam guiding mechanism and the centering hydraulic cylinder 8 of roll gap centering body are adjusted to preset definite value with the gap of two rolls 3,2; The roll gap that guarantees each milling train is centered close on the rolling centerline, satisfies rolling requirement.
After setting in the roll gap center, carry out the roll seam adjustment in the continuous rolling, referring to Fig. 1, rolled piece 12 passes two rolls 3, roll gap between 2 along rolling centerline A-A, rolled piece is carried out vertically vertically rolling by the body of roll of two rolls.According to rolling requirement, control hydraulic cylinder for reduction system 9 is implemented topping roll 3 and is moved adjustment; Control centering hydraulic cylinder 8 simultaneously, the mobile adjustment of the half trip relatively of floating type frame 11 and bottom roll 2 makes two roll seams adjust to setting value, and the roll gap center is constant simultaneously.
In like manner; The mechanical type transmission mechanism of said roll seam guiding mechanism is that a cover or two covers are depressed worm-and-wheel gear; For the described two roller horizontal mills of the utility model with Contiuum type bearing block, the said worm-and-wheel gear of depressing is a cover, referring to Fig. 4,5; For the described two roller horizontal mills of the utility model with split type bearing block, the said worm-and-wheel gear of depressing is two covers, referring to Fig. 6.Every cover is depressed worm-and-wheel gear and is comprised: be arranged on screw box 23 on the entablature of said floating type frame 11; The depress spiro rod 18-1 that is threaded with screw box 23; Depress spiro rod 18-1 through connecting key 24 with depress worm gear 21 and be connected; Depress worm gear 21 and depress worm screw 22 engagements, this depresses worm gear 21, depress worm screw 22 and bearing 31 is installed in the reduction case 32 together, and reduction case 32 is fixedly connected with the entablature of floating type frame 11.The said worm gear 21 of depressing is fastenedly connected with connecting key 24, and connecting key 24 is slidingly matched with the keyway of depress spiro rod 18-1.When being a cover when depressing worm-and-wheel gear, the bottom of said depress spiro rod 18-1 is placed on the topping roll bearing block 4.When being that two covers are when depressing worm-and-wheel gear; The bottom of depress spiro rod 18-1 in the two cover mechanisms is placed on respectively on the topping roll bearing block 15,16; Two covers in the mechanisms depress worm screw 22 through shaft coupling 34 with depress motor 33 and be connected, depress for two and be provided with clutch 35 between the worm screw 22.
