Description

The main frame top and bottom rolls double driving mechanism of a kind of cold-rolling mill, foil mill

Technical field

The utility model belongs to the Driving technique field of cold-rolling mill, foil mill, mainly proposes the main frame top and bottom rolls double driving mechanism of a kind of cold-rolling mill, foil mill.

Background technology

The cold-rolling mill of metals such as present aluminium alloy, steel band and copper alloy and the main frame of foil mill mainly are divided into two kinds; A kind of is four-high mill (working roll driving); A kind of is six-high cluster mill (intermediate calender rolls driving); No matter be four-high mill or six-high cluster mill, it acts on the top roll, the lower roll that need rolling rolled piece and all adopts one group of separate unit or multiple electric motors to drive: group of motors links to each other with reductor through shaft coupling, drives upper and lower roll simultaneously through Hooks coupling universal coupling, branch tooth case then.Described reductor links to each other with a minute tooth case through shaft coupling; Be connected with top roll, lower roll respectively through two Hooks coupling universal couplings by minute tooth case again; For top roll and lower roll provide power, make top roll and lower roll keep the same angular velocity of rotation to guarantee that top roll is consistent with lower roll speed, the still such designing requirement top roll and the diameter basically identical of lower roll; But the wearing and tearing of top roll and lower roll are difficult to guarantee consistent in the prior art; So the diameter that often occurs after top roll and the lower roll grinding is inconsistent, such situation is different according to the rolled piece thin and thick usually, selects to grind some to bigger roll more; If make top roll consistent with lower roll or rolled piece is thicker, roller diameter is inconsistent can ignore.If rolled piece end bending and rolled piece surface abrasion appear in the inconsistent meeting of roller diameter, if direction not to, nose is excessive and surface abrasion all can influence and batches and final finished.

Roll is generally using; If reason or cause for quality make wherein a roll scrap because wearing and tearing differ; Can't find the roll of coupling again and don't want and be whittled into the roll that matees with the old roller of also not scrapping to new roll; This root also will be forced to scrap probably so, certainly will increase production cost like this.

The utility model content

For solving the problems of the technologies described above, the purpose of the utility model is the main frame top and bottom rolls double driving mechanism that proposes a kind of cold-rolling mill, foil mill.

The utility model adopts following technical scheme for accomplishing its invention task:

The main frame top and bottom rolls double driving mechanism of a kind of cold-rolling mill, foil mill is provided with group of motors I, group of motors II respectively to top roll, the lower roll that is applied to rolling rolled piece; The top roll of described group of motors I through reductor, Hooks coupling universal coupling I and milling train is connected to top roll provides power; The lower roll of described group of motors II through reductor, Hooks coupling universal coupling II and milling train is connected to lower roll provides power, and the driving mechanism of top roll, lower roll that constitutes milling train is separate, the adjustable main frame top and bottom rolls double driving mechanism of relative velocity of top roll, lower roll.

Described reductor is a combined reducing gear unit.

Described reductor is two, the reductor I, the reductor II that promptly are provided with separately.

A kind of cold-rolling mill that the utility model proposes, the main frame top and bottom rolls double driving mechanism of foil mill, adopt technique scheme to have following beneficial effect:

(1) can guarantee that at top roll, when lower roll roller footpath is inconsistent main frame up-down rollers linear velocity is consistent, thereby guarantee rolled piece upper and lower surfaces quality and consistent template.

(2) allow aborning top roll, lower roll grinding roller amount inconsistent, need not because of the greatly painstakingly many grindings of wear extent departure roll bigger than normal, thereby prolong roll campaign.

(3) because top roll, the lower roll relative velocity is adjustable, the nose of rolled piece is controlled, painstakingly according to take-up direction (on batch or batch down) adjustment rolled piece end bending, as: on when batching, the main frame top roll is set drives faster than the lower roll driving, make countersunk head under the rolled piece (having a downwarp); And under when batching, the main frame lower roll is set drive faster than top roll and drive, make nose on the rolled piece (upwarping).Can make things convenient for the rolling-assisting device stub bar of nipping like this, conveniently batch.

(4) avoided using branch tooth case, not only the laborsaving cost of joint investment owing to reduced branch tooth case, has reduced loss point, has also reduced operating cost.Also practiced thrift floor space simultaneously, the user nervous for the workshop area is no small saving.

(5) after the transmission of top roll, lower roll separately, the angle of Hooks coupling universal coupling no longer receives the restriction of branch tooth case gear size, can make Hooks coupling universal coupling more open and more flat according to center layout in the scope of activities of up-down rollers, and shaft coupling can shorten, and transmission accuracy is higher.
