The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1; Roll axial adjusting device of the present invention; Comprise a pair of topping roll 501, a pair of bottom roll 502; Topping roll 501 and bottom roll 502 are installed on the upper/lower terminal of roller system of rolling mill respectively through time Coupling Shaft, the left and right two ends of topping roll 501 and bottom roll 502 are separately installed with the roll axial adjusting device;
Roll axial adjusting device structure is (mounting structure with topping roll 501 is an example): first time Coupling Shaft in topping roll 501 two ends 4, second time Coupling Shaft 6 place are equipped with first oil cylinder 1 and second oil cylinder 9 respectively; The contact-making surface that the end of first piston bar 2 ends of first oil cylinder 1 and second piston rod 8 of second oil cylinder 9 is connected with first push pedal 3 and second push pedal, 7, the first push pedals 3 and second push pedal 7 respectively respectively with roll two ends butt.
The mounting structure of push pedal is (mounting structure with first push pedal 3 is an example): the end of first piston bar 2 ends of first oil cylinder 1 and second piston rod 8 of second oil cylinder 9 has internal thread; Like Fig. 2 and Fig. 3; First push pedal 3 comprises a square block 302; The top of square block 302 is provided with two locating holes 301; The perpendicular direction in square block 302 bottoms is extended with projecting shaft 303, and projecting shaft 303 is provided with the external screw thread that is connected with screw-internal thread fit that piston rod is opened, and is formed with the contact-making surface 304 with a pair roller butt on the square block 302 of set projecting shaft 303 other ends; Be positioned at first oil cylinder, 1 top and be provided with chute 11, in the locating hole 301 of square block 302 guide post 10 is installed, guide post 10 slides in chute 11 vertically, on each identical oil cylinder identical guiding mechanism is set.The structure of the roll axial adjusting device of bottom roll 502 is identical with the roll axial adjusting device of above-mentioned topping roll 501.
In the actual use, when roll mandrel when needs move, start each oil cylinder work through displacement transducer (not drawing among the figure); Oil-feed in first oil cylinder 1 promotes first piston bar 2 and stretches out, and (shown position among Fig. 1) promptly moves right; The power of first piston bar 2 is passed to first push pedal 3, thereby topping roll 501 is moved right, and guide post 11 moves right in chute 10; Simultaneously; Second piston rod, 8 withdrawals of second oil cylinder 9, promptly move right (shown position among Fig. 1) realized moving right of topping roll 501 easily; When 9 oil-feeds of second oil cylinder, second piston rod 8 stretches out, and second piston rod 8 promotes second push pedal 7 and is moved to the left (shown position among Fig. 1); Simultaneously, fuel-displaced in first oil cylinder 1,2 withdrawals of first piston bar; Promptly be moved to the left (shown position among Fig. 1); Thereby topping roll 501 is moved to the left, promptly, has realized that easily a pair of topping roll 501 moves axially through being used of topping roll 501 two ends, first oil cylinder 1 and second oil cylinder 9; Adopt identical method can realize moving axially of a pair of bottom roll 502 easily.
The present invention is simple in structure, and is easy and simple to handle, and an oil cylinder is controlled moving axially of a pair roller simultaneously, and production efficiency is high, and through displacement transducer control, its response is fast, uses flexibly, and the adjustment precision is high.
