Abstract
The invention relates to a crown adjusting device of a multi-roller cold rolling mill, in particular to a roller crown adjusting device used by a twenty-roller rolling mill. The crown adjusting device is characterized in that a drive assembly is connected with a mount bracket through a hydraulic oil cylinder; the mount bracket is fixedly arranged on a framework; a connection rod is used for connecting a piston rod of the hydraulic oil cylinder and a double-sided rack; an indicator is arranged on the piston rod of the hydraulic oil cylinder; and the double-sided rack is engaged with fan-shaped gears on two middle-upper support roller groups of an execution assembly. An eccentric ring is arranged on the mandrel of the support roller groups and is arranged in a saddle, the fan-shaped gears are distributed on both sides of the eccentric ring and are connected with the eccentric ring, and the saddle is arranged on both sides of a back-up bearing. The crown adjusting device has the advantages of reasonable structure, convenient adjustment, hydraulic operation, high response speed, short calibration time and high sensitivity, and can meet the requirement of better board shape adjusting capacity of the roller system of the multi-roller cold rolling mill and can improve the quality of the final product.
Description
Technical field
The present invention relates to a kind of convexity adjusting apparatus of multiple rollers cold calender, the roll crown adjusting device that especially uses on the Sendzimir mill (also claiming radially roll forming adjusting device of roll).
Background technology
Multiple rollers cold calender, especially Sendzimir mill, roller system arranges and adopts tower rollers system; Tower rollers is fastened down and is arranged in the up-down rollers case symmetrically or is arranged in the quincunx hole of whole frame.This roller is that arrangement space is arranged all very compactness, and working roll, intermediate calender rolls can't be provided with the roll crown adjusting device, all adopts backing roll to carry out the convexity adjustment and eliminates the uneven problem by the local thickness of rolled piece.The roll crown guiding mechanism is not set on the multiple rollers cold calender that has at present; Installation one cover hydraulic motor, the worm-gear speed reducer that has drives two-sided tooth bar motion adjustment roll forming, and this mechanism response speed is slow, correction time is long, sensitivity is low.The roll radially quality of roll forming adjustment is the key of cold-rolling mill shape control ability.Therefore need a kind of more reasonable structure of design, adjust the roll crown adjusting device of better effects if.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of rational in infrastructure, use easy to adjustly, adapt to the new roller convexity adjusting apparatus that multiple rollers cold calender roller system requires to have better plate shape adjustment capability.
The main solution of invention is achieved in that
The present invention includes frame, driven unit, indication piece and executive module; Driven unit adopts hydraulic jack to be connected on the mounting bracket, and mounting bracket is fixedly mounted on the frame; Connecting rod connects the piston rod and the two-sided tooth bar of hydraulic jack, and indication piece is installed on the piston rod of hydraulic jack, the sector gear sheet engagement on two groups of backing roll groups of the middle upper portion of two-sided tooth bar and executive module.
Setting-up eccentricity ring on the axle of described backing roll group, sector gear sheet are distributed in the eccentric hoop both sides and are connected with eccentric hoop, and eccentric hoop is installed in the saddle, and saddle is arranged in the both sides of back lining bearing.Described indication piece is the slide bar type indicating dial.
Compared with the prior art the present invention has the following advantages:
The present invention is rational in infrastructure, uses easy to adjust; Hydraulic operation is finished, and response speed is fast, correction time is short, highly sensitive; Can satisfy multiple rollers cold calender roller system has the requirement of better plate shape adjustment capability, and can improve the mill product quality.
Description of drawings
Fig. 1 is a roll crown adjusting device structural representation of the present invention.
Fig. 2 is a supporting roller assembly structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 2: comprising: compositions such as hydraulic jack 1, slide bar type indicating dial 2, connecting rod 3, mounting bracket 4, frame 5, two-sided tooth bar 6, backing roll group 7, axle 8, back lining bearing 9, eccentric hoop 10, sector gear sheet 11 and saddle 12.
The present invention includes driven unit, indication piece and executive module.The roller system of multiple rollers cold calender adopts the tower rollers system of symmetric arrangement up and down.
As shown in Figure 1: described driven unit adopts hydraulic jack 1 to be connected on the mounting bracket 4, and mounting bracket 4 is fixedly mounted on the frame 5; Connecting rod 3 links up the piston rod and the two-sided tooth bar 6 of hydraulic jack 1; Described indication piece slide bar type indicating dial 2 is installed on the piston rod of hydraulic jack 1, the sector gear sheet engagement on two-sided tooth bar 6 and two groups of backing roll groups 7 of middle upper portion.Hydraulic jack 1 drives two-sided tooth bar 6 by connecting rod 3 and moves up and down, and drives slide bar type indicating dial 2 simultaneously and moves up and down.According to the quantity of saddle, all be furnished with actuator at each saddle place.
As shown in Figure 2: described executive module is two groups of backing roll groups 7 of middle upper portion.Setting-up eccentricity ring 10 on the axle 8 of described backing roll group, eccentric hoop 10 are installed in the saddle 12, and sector gear sheet 11 is distributed in eccentric hoop 10 both sides and is connected with eccentric hoop 10 with pin.Because two-sided tooth bar 6 and 11 engagements of sector gear sheet, moving up and down of hydraulic jack 1 can drive eccentric hoop 10 revolutions.
Each saddle 12 place's hydraulic jack 1 drives two-sided tooth bar 6 and drives eccentric hoop 10 revolutions by sector gear sheet 11, because saddle 12 is fixed with respect to the plum blossom bore hole of frame, and eccentric hoop 10 is eccentric with respect to plum blossom bore hole center, therefore backing roll group axle 8 produces distortion at this saddle position, thereby backing roll group back lining bearing 9 positions at this saddle place are changed, reaching roll crown with this changes, controlled rolling plate shape, the convexity variable quantity shows by slide bar type indicating dial 2.
