Abstract
The utility model relates to a four roller full hydraulic rolling machine, belonging to the field of rolling machines for continuously rolling straps or plates with different length. The rolling machine comprises a machine frame, a supporting roller, a working roller, a deoiling roller and a clamping plate; besides, the utility model is provided with a hydraulic device which is matched with the rolling machine and comprises a pressing hydraulic cylinder, a hydraulic cylinder for balancing a supporting roller, a roller changing hydraulic cylinder, a roller bending hydraulic cylinder, a roller deoiling hydraulic cylinder and a plate clamping hydraulic cylinder; therefore, rolling gaps can be set and trimmed online to realize hydraulic control and improve the precision of the longitudinal and lateral dimensions of rolled products.
Description
The utility model belongs to the band that is used for the continuous rolling indefinite length or the milling train field of plate.Mainly be applicable to and produce high-precision cold-strip steel.
Along with rapid development of national economy, have higher requirement to the dimensional accuracy of cold-strip steel in fields such as industry, building and civil electric appliance, is ± 8 μ m as electrolytic tinplate to the requirement of cold-strip steel raw materials size tolerance.
The four-high mill of existing production medium-width cold-strip steel as 650 milling trains, does not all adopt the hydraulic pressure micromatic setting in its frame, vertical tolerance that can not online adjustment steel band.This class milling train is when producing, at first adjust roll gap under the electricity consumption dynamic pressure, no longer regulate in the operation of rolling, thereby, can not realize online feedback compensation to the factors such as raw band varied in thickness, mill speed variation and roll forming of the roll variation that occur in the operation of rolling, the band steel of being produced like this, its dimensional accuracy is lower, does not reach high dimension precision requirement.
The purpose of this utility model is to provide a kind of all-hydraulic milling train of four rollers that is used for rolling high dimensional accuracy cold-strip steel.
The all-hydraulic milling train of four rollers described in the utility model is a single stand reversible rolling mill.It except comprise frame, backing roll, working roll, deoil roller and the clamping plate, also contain: backing roll balance hydraulic cylinder, the roll change hydraulic cylinder of hydraulic cylinder for reduction system, roller hydraulic cylinder and backing roll coupling, with the roller hydraulic cylinder that deoils of the roller coupling of deoiling, the clamping plate hydraulic cylinder that is complementary with clamping plate.
Be that the utility model has adopted hydraulic pressure micromatic setting, hydraulic roller-bending device, hydraulic balance device, the hydraulic pressure changing rig of backing roll, the hydraulic means of deoil roller and clamping plate.Make balance, roll change, deoil roller and the clamping plate of setting roll gap, on-line fine roll gap, roller and backing roll of this milling train all adopt hydraulic control.Thereby improve the vertical and horizontal dimensional accuracy of rolled products.
The hydraulic pressure micromatic setting is used for vertical tolerance of On-line Control steel band, in the operation of rolling On-line Control is carried out in the variation of raw band varied in thickness, tension force and the variation of mill speed etc., makes the vertical tolerance of steel band after rolling in target zone.Hydraulic roller-bending device is used to control the horizontal tolerance of steel band, improves the plate shape of finished product steel belt by the convexity of adjusting roll.The effect of the hydraulic balance device of backing roll is the balance top backing up roll.The effect of hydraulic pressure changing rig is to lift roll, is beneficial to the roll in the roll change buggy replacing frame.The effect of roller hydraulic control device of deoiling is to regulate the distance of deoiling between roller, makes it to adapt with the thickness of steel band.The clamping plate hydraulic control device is to regulate the distance between clamping plate, makes clamping plate clamp steel band, keeps certain force of strain, prevents the steel band vibration.
The utility model is applicable to belt steel products such as rolling straight carbon steel, Fine Steel Casting iron, spring steel and stainless steel.The product size precision height that is shut out.
Compared with prior art, the utlity model has following advantage:
1, improved the cold-rolled strip dimensional accuracy of products.Owing to use the hydraulic pressure micromatic setting, the longitudinal thickness tolerance of steel band be controlled in the high accuracy scope.
2, improved the automaticity in the production process.Because bascule, the changing rig of backing roll, deoil roller and clamping plate have all adopted hydraulic control, have improved the control level.
3, the screw-down of equipment is simplified.All realize owing to depress fast, saved and depressed motor and deceleration device above the frame by the big stroke hydraulic cylinder that is positioned at above the backing roll with fine adjustment function.
Now the utility model is described in further detail according to accompanying drawing.
Accompanying drawing 1 is the structural representation of the all-hydraulic milling train of the utility model four rollers.
1 is assistance platform in the accompanying drawing; 2 are the roller hydraulic cylinder that deoils; 3 is the clamping plate hydraulic cylinder; 4 is frame; 5 is hydraulic cylinder for reduction system; 6 is backing roll; 7 is working roll; 8 is the roller hydraulic cylinder; 9 is the backing roll balance hydraulic cylinder; 10 are the roll change hydraulic cylinder; 11 is backing plate.
Hydraulic cylinder for reduction system 5, roller hydraulic cylinder 8, backing roll balance hydraulic cylinder 9, roll change hydraulic cylinder 10, backing roll 6 and working roll 7 are installed in the frame 4.Deoil roller hydraulic cylinder 2 and clamping plate hydraulic cylinder 3 is installed on the assistance platform 1 before and after the milling train.
Claims (2)
