Abstract
The invention provides a continuous annealing line rectification upper roller demounting and mounting method. The method includes the steps of demounting an air cylinder of an upper roller frame, hoisting an upper roller, demounting an upper cover of a bearing seat of the upper roller, placing the upper roller between two lower rollers, hoisting and opening the upper roller frame, fixing the upper roller frame by safety pins, hoisting and horizontally moving the upper roller, placing a new roller between the two lower rollers, removing the safety pins of the upper roller frame, closing the upper roller frame, resetting the new roller, installing a bearing in the bearing seat and fastening the bearing to make the new roller normally rotate, installing the air cylinder of the upper roller frame, and opening a pneumatic device and a hydraulic medium. The demounting and mounting method is simple and fast, can greatly shorten replacement time, relieves labor intensity of operators, improves working efficiency, guarantees smooth conduction of continuous annealing production, and meanwhile can eliminate hidden dangers and completely eradicate safety accidents.
Description
Technical field
The invention belongs to cold rolling mechanical apparatus field, relate in particular to a kind of cold rolled silicon steel continuous annealing production line three roller correcting device top rolls and change assembly and disassembly methods separately.
Background technology
The cold rolled silicon steel continuous annealing production line in the continuous annealing furnace exit, is provided with a correcting device of being made up of three rollers, and three rollers adopt the set-up mode of two lower rolls, a top roll.One on top roll frame is the hinge connection, and the both sides, other end are controlled by cylinder, and can lift.Because continuous annealing heater outlet temperature height though correction roller glue face adopts special material, is compared with the glue face of other rubber roll, defective very easily appears in the glue face of this top roll, so the replacing of top roll is more frequent.
When top roll is changed, be top roll frame cylinder to be pulled down back top roll being sling together with the top roll frame with bridge crane open in the past, fix with safety pin again, operating personnel will stand in lower roll framework and lower roll surface dismounting top roll, not only the replacing time long, labour intensity is big, operating efficiency is low; And lower roll framework and lower roll surface are more sliding, and unstable, very easily cause security incident, have greatly potential safety hazard.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple, can change top roll fast, improves operating efficiency, avoids the independent assembly and disassembly methods of continuous annealing production line correction top roll of security incident.
For this reason, the solution taked of the present invention is:
Line correction top roll assembly and disassembly methods moves back in a kind of company, and the step that its top roll is changed separately is:
1, before the top roll dismounting, stops and close pneumatic means and hydraulic medium.
2, remove top roll frame cylinder, hang steel cable and hang top roll; Remove top roll split-type shaft bearing loam cake, top roll is fallen be placed in the middle of two lower rolls then, pluck steel cable.
3, the extension steel cable is sling the top roll frame and is opened, and fixes with safety pin, plucks steel cable.
4, top roll is sling, level shifts out.
5, new roller is sling, level moves into and is placed in the middle of two lower rolls; Top roll frame safety pin is withdrawn from, and the top roll frame is sling and is closed.
6, new roller is sling and is placed into the installation position, and bearing is installed in the bearing block, and fastening bearing block bolt checks new roller rotation situation.
7, top roll frame cylinder is installed, is opened pneumatic means and hydraulic medium.
Beneficial effect of the present invention is:
Assembly and disassembly methods of the present invention is simple, and is efficient and convenient, can greatly shorten the replacing time, alleviates operating personnel's labour intensity, increases work efficiency, and guarantees carrying out smoothly of continuous annealing production; Simultaneously and since top roll when changing the operating personnel can stand in both sides work and needn't enter in the correcting device framework, thereby can remove a hidden danger, stop security incident.
Description of drawings
Fig. 1 is three roller correcting device structural representations.
Among the figure: lower roll 1, top roll 2, top roll frame 3, top roll frame cylinder 4.
The specific embodiment
As seen from Figure 1, three roller correcting devices mainly are made up of two lower rolls 1, top roll 2, top roll frame 3, top roll frame cylinder 4 and a reference axis bearing.Top roll frame 3 one ends are hinged, and it lifts or falls the other end by 4 controls of top roll frame cylinder.
The present invention connects the concrete steps of moving back the independent assembly and disassembly methods of line correction top roll:
1, before top roll 2 dismountings, closes pneumatic means and hydraulic medium, and contact the processing of stopping with production operation department.
2, at first, remove top roll frame cylinder 4, hang steel cable and hang top roll 2.Then, remove the split-type shaft bearing loam cake of top roll 2, again top roll 2 is fallen the centre that is placed on two lower rolls 1, remove steel cable.
3, steel cable is suspended on the top roll frame 3, top roll frame 3 is sling opened, and fix with safety pin, remove steel cable.
4, steel cable is suspended on the top roll 2, top roll 2 is sling, level shifts out.
5, the new roller of desiring to change is sling, level moves into the centre that is placed on two lower rolls 1; The top roll frame 3 of slinging is again withdrawn from the safety pin of top roll frame 3, top roll frame 3 is sling closed then.
6, new roller is sling be placed into the installation site, bearing is installed in the bearing block fastening bearing block bolt, the new roller rotation situation of manual examination (check).
7, all normal after, install top roll frame cylinder 4 after, open pneumatic means and hydraulic medium again, namely finish the replacing disassembly process of whole top roll 2.
