Abstract
The utility model relates to a 22-roll cold roller which can be used for the production of various micron-level and metal-level thin strip material, comprising work rollers with a minor diameter, supporting rollers, back lining bearing rollers and a machine frame. The roller arrangement comprises two work rollers [5] with a minor diameter, four supporting rollers [4] on the first floor, six supporting rollers [3], four supporting roller [6] on the third floor, two large supporting rollers [7], and four back lining bearing rollers [2] at the two sides of the supporting rollers [3] on the second floor. The two large supporting rollers [7] are adopted as transmission rollers. The utility model has the advantages of simple structure, convenient manufacture and low cost. When the diameter of the work rolls [5] is 2 millimeters, the utility model can roll various metal-level thin strip material with a minimum thickness of 0.001 millimeters.
Description
The utility model relates to a kind of 22 cold mills, can be used for the production of sheet metal strip as thin as a wafer of various micron orders, is particularly useful for the production of difficult deformable metal ultra-thin strip.
The minor diameter working roll is one of most important condition of rolling ultra-thin strip.By the M.D.stone formula calculate or experiment as can be known, the minimum finished product thickness of cold-rolling mill is about 1/1000～1/2000 of work roll diameter, therefore wanting rolling thickness is O.001 millimeter finished product, the work roll diameter of milling train must be in 2 millimeter.In the prior art, 36 cold mills of the former Soviet Union and China are seen Fig. 4; 30 cold mills of Japan and China are seen Fig. 3; And 26 cold mills of the former Soviet Union, see Fig. 5, all have this feature.It is the requirement of rigidity that their many support roller structure has satisfied roller simultaneously.Existing weak point is: complex structure, and particularly its roller case manufacturing technology difficulty is big, and cost is also high.Have 4 live-rollers at least, also make drive apparatus be tending towards complicated.
Chinese patent CN91205587.1 discloses a kind of " ten mkw mills that have the roll shape adjusting device ".Its roller system formation is made up of 2 working rolls, 4 side support roller, 2 intermediate calender rolls, 2 big support roller and 8 backing cloth bearing rollers.Simple in structure, easily manufactured.Have intermediate calender rolls and backing cloth bearing roller roll shape guiding mechanism owing to it simultaneously, thereby can adjust roll shape easily.But its roller system arranges and has determined it can not adopt the too little working roll of diameter, thereby can not produce micron-sized metal ultra-thin strip.
The purpose of this utility model provides a kind of 22 cold mills, both can produce various micron order metal ultra-thin strips, satisfies requirement simple in structure, easily manufactured, that cost is low again.
The purpose of this utility model realizes by following measure.The arrangement of its roller system is made up of 2 minor diameter working rolls, 4 ground floor support roller, 6 second layer support roller, 4 the 3rd layer of support roller, 2 big support roller and 4 backing cloth bearing rollers that are positioned at second layer support roller both sides.Two big support roller are live-roller.
The advantage that the utility model is compared with prior art had is: guaranteeing that minor diameter working roll and roller are rigidity,, simplifying roll system structure to satisfy under the prerequisite of producing micron order metal ultra-thin strip needs, and therefore simple in structure, easily manufactured, cost is lower.Two big support roller also are simplified the drive apparatus of this milling train as live-roller.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the utility model 22 cold mills.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is a Pareto diagram for the roller of 30 cold mills in the prior art.
Fig. 4 is a Pareto diagram for the roller of 36 cold mills in the prior art.
Fig. 5 is a Pareto diagram for the roller of 26 cold mills in the prior art.
By Fig. 1,2 as seen, its roller system of the utility model 22 cold mills arranges and is made up of 4,6 second layer support roller of 5,4 ground floor support roller of 2 minor diameter working rolls, 6,2 big support roller 7 of 3,4 the 3rd layer of support roller and 4 backing cloth bearing rollers 2 that are positioned at second layer support roller 3 both sides.Whole roller is to be installed in the unit frame 1.Each backing cloth bearing roller 2 is made of at least 3 back lining bearings 8, saddle 9 and a single mandrel 10, by the window position of frame 1.Big support roller 7 adopts the support roller of conventional mill, and as live-roller.
The utility model 22 cold mills can be in place, the gateway of frame 1 installs as Chinese patent CN91205587.1 " ten mkw mills that have the roll shape adjusting device " disclosed backing cloth bearing roller roll shape guiding mechanism.
Adopt 22 cold mills among the utility model embodiment, when the diameter of working roll 5 is 2 millimeters, can roll out minimum thickness and only be 0.001 millimeter various sheet metal strips as thin as a wafer.
Claims (2)
1, a kind of 22 cold mills, comprise minor diameter working roll, support roller, backing cloth bearing roller and frame, it is characterized in that: its roller system arranges and is made up of 2 minor diameter working rolls [5], 4 ground floor support roller [4], 6 second layer support roller [3], 4 the 3rd layer of support roller [6], 2 big support roller [7] and 4 backing cloth bearing rollers [2] that are positioned at second layer support roller [3] both sides, and two big support roller [7] are live-roller.
