Abstract
The utility model discloses a four-roller cold rolling machine comprising a rolling machine frame; four rollers are arranged in parallel on the rolling machine frame from top to bottom; a supporting roller is arranged on the working roller at the upper end and the lower end; a roller bending device is arranged on two middle working rollers; the supporting roller and the working roller can rotate respectively; a conveying platform is arranged in the rolling direction of the working roller; and the conveying platform is provided with a transmission chain. In the utility model, the four-roller cold rolling machine leads the plate to be rolled on the conveying chain in the cold rolling process, controls the conveying chain by a control platform, thus driving the plate to be rolled to enter the space between two working rollers so as to be rolled; the oil of a lubricant oil pipe is sprayed on the supporting roller and the working roller so as to effectively reduce the friction coefficient and the corresponding rolling force; and during the hot rolling process, the working roller can be removed, therefore, two procedures can be completed by one machine, therefore, the manufacturing cost can be saved.
Description
Technical field
The utility model belongs to the milling equipment technical field, is specifically related to a kind of 4-roller cold rolling mill.
Background technology
Cold rolling is that the blank (or coil of strip) that provides with hot rolling is rolling raw material, carries out cold continuous rolling behind the pickling scale removal, single chassis is cold rolling or monolithic is rolling, mainly is that any surface finish, dimensional accuracy are high through the products characteristics of cold rolling process.Metal material after cold deformation, there is the work hardening phenomenon in metal inside, intensity, hardness rising, the tough index of moulding of rolled piece are descended, therefore cold-rolled products should be through heat treatment, reduce the phenomenon punching performance and will worsen to eliminate historrhexis that cold rolling processing causes and plasticity, can only be used for the part of simple deformation.
The milling train of the existing cold rolling usefulness of metallurgical processing industry does not generally possess the function of hot rolling, so the milling train that also needs an other cover hot rolling to use in the middle of the process that is rolled has so just increased the cost of making.
Summary of the invention
The purpose of this utility model provides a kind of 4-roller cold rolling mill, promptly can carry out cold rollingly, also can carry out hot rolling, thereby save manufacturing cost.
The technical scheme that the utility model adopted is, a kind of 4-roller cold rolling mill, comprise mill stand, on the mill stand, be arranged side by side four working rolls successively from top to bottom, the working roll at two ends is provided with backing roll up and down, and middle two working rolls are provided with to bend and roll roller arrangement, and backing roll, working roll can rotate around working roll respectively, rolling direction at working roll is provided with transfer station, and transfer station is provided with driving-chain.
Feature of the present utility model also is,
Mill stand is provided with lubricated flowline.
Working roll is connected with console, power distribution cabinet in turn by control line, and console also is connected with transfer station by control line.
The utility model 4-roller cold rolling mill, when cold rolling, plate to be rolled is placed on the chain of transmission device, thereby driving plate to be rolled by console control driving chain enters between two working rolls and is rolled, rolling lubrication is sprayed on backing roll and the working roll with the oil of flowline the inside, make that effectively to reduce coefficient of friction, corresponding roll-force, required power low, obtain satisfied rolled products; For making the rolled plate surface smoothness improve, roll that to prolong thickness even; In lubricated, realized that cooling combines with lubricated effectively.Can take away the rolling heat that produces in the cold-rolled process rapidly, protection roll and rolled piece.When hot rolling, only need take down working roll and get final product, thereby on a machine, can finish the operation of diverse two procedures, thereby save manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of the utility model two roller hot-rolling mills.
Among the figure, 1. transfer station, 2. driving-chain, 3. mill stand, 4. backing roll, 5. working roll, 6. console, 7. power distribution cabinet, 8. roll-bending device, 9. lubricated flowline.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model 4-roller cold rolling mill as shown in Figure 1, comprise mill stand 3, on mill stand 3, be arranged side by side four working rolls 5 from top to bottom successively, the working roll 5 at two ends is provided with backing roll 4 up and down, middle two working rolls 5 are provided with roll-bending device 8, backing roll 4, roll-bending device 8 can rotate around working roll 5 respectively, on mill stand 3, backing roll 4 facing to the upper end is provided with lubricated flowline 9, rolling direction facing to working roll 5 is provided with transfer station 1, transfer station 1 is provided with driving-chain 2, and backing roll 4 also is connected with console 6 in turn by control line, power distribution cabinet 7, console 6 also are connected with transfer station 1 by control line.
The use of the utility model 4-roller cold rolling mill is, when cold rolling, plate to be rolled is placed on the driving-chain 2, thereby driving plate to be rolled by console 6 control driving-chains 2 enters between two working rolls 5 and is rolled, power distribution cabinet 7 provides power for working roll 5 for console 6 and transfer station 1, backing roll 4 is driving wheels, working roll 5 is driven pulleys, the oil of lubricated flowline 9 the insides is sprayed on the backing roll 4, make and effectively reduce coefficient of friction, corresponding roll-force and required power, obtain satisfied rolled products; Make product surface highly polished, roll that to prolong product thickness even; The oil of lubricated flowline 9 the insides plays favorable cooling effect, and can take away rolling heat rapidly, protection roll and rolled piece.When hot rolling, only need take out working roll 5 and get final product, change hot roll, thereby can finish the operation that originally on two machines, just can finish on the machine, greatly reduce the manufacturing expense of factory.
The utility model 4-roller cold rolling mill can roll out long 2m-3m, wide 0.4m-1.05m, thick 0.2cm-3cm metallic plate.Dimensional accuracy has improved the operating rate of high speed panel production line in ± 0.03mm-0.2mm scope, reduced the specific yield production cost, has improved the business economic benefit.
