Abstract

The utility model discloses a novel rolling mill device, comprising rectification rolls, a large coiling block and an uncoiler. Supporting rolls are arranged on upper and lower external circles of two working rolls correspondingly; five pressing rolls are arranged along the same direction with the working rolls and at both ends of the same horizontal line respectively; the rectification rolls are positioned outside the five pressing rolls respectively; the large coiling block is mounted outside one rectification roll, and a small coiling block is installed at lower parts between the rectification roll and the large coiling block; the uncoiler is arranged outside another rectification roll, and the large coiling block is installed between the lower parts of the rectification roll and the uncoiler. The novel rolling mill device has simple structure and low cost, is applicable to processing rolled thin strip materials in small and medium-sized enterprises, ensures product quality, and improves production efficiency greatly.

Description

A kind of novel rolling mill assembly

Technical field

The utility model relates to a kind of novel rolling mill assembly, and it is applicable to rolling thin strip.

Background technology

In the copper process, milling train is being undertaken the important process equipment of rolled piece thickness and target thickness variation, and its purpose makes rolled piece roll thinner and thinner exactly; Finish to gauge is to target thickness; Because receive the constraint of all kinds of change condition, the original blank that plate shape is good is in process; The quality of its plate shape, depend on strip along on the cross direction extension whether equate.When the bilateral wave that then produces symmetry when extending greater than the middle part is extended on the strip both sides, on the contrary wave in the middle of then producing, when the power of depressing when both sides is inconsistent, when power of then depressing and area are big, one side i.e. extension also big produce single wave or lateral bending.Vertical when wave at rolled piece, when laterally increasing simultaneously, then can produce the wooden dipper song.Along wide to the longitudinal extension difference big more, the additional stress in the rolled piece is high more, flatness defect is just serious more.So present medium-sized and small enterprises are limited by expensive cost of equipment, exist the processing band and can not guarantee product quality, the problem that productivity ratio is low.

Summary of the invention

The purpose of the utility model is exactly that a kind of novel rolling mill assembly will be provided, and it can overcome the problem that existing milling train exists.The purpose of the utility model is achieved in that a kind of novel rolling mill assembly, comprises that rectification roll, parent roll, uncoiler form, and it is characterized in that: the correspondence of outer ring up and down of two work rods is provided with support stick; Be provided with in the same way with the work rod and two ends on same horizontal line are respectively arranged with five nip rolls; The outside of five nip rolls is respectively arranged with the local derviation rod, and the arranged outside of one of them local derviation rod has parent roll, and below between local derviation rod and the parent roll, is provided with little reel; The arranged outside of another local derviation rod has uncoiler, and below between local derviation rod and the uncoiler, is provided with parent roll.The utility model is simple in structure, and cost is low, is adapted to the processing of medium-sized and small enterprises to rolling thin strip, and can guarantees product quality, has improved production efficiency greatly.

Description of drawings:

Fig. 1 is the utility model structural representation;

1. parent roll, 2. little reel, 3. rectification roll, 4. five pressure rollers, 5. backing roll, 6. working roll, 7. five pressure rollers, 8. rectification roll, 9. parent roll, 10. uncoiler.

The specific embodiment: the utility model is described further below in conjunction with accompanying drawing;

A kind of novel rolling mill assembly comprises rectification roll 3, parent roll 1,10 compositions of uncoiler, it is characterized in that: the correspondence of outer ring up and down of two work rods 6 is provided with support stick 5; Be provided with in the same way with work rod 6 and two ends on same horizontal line be respectively arranged with 4 five nip rolls 7 of five nip rolls; The outside of five nip rolls is respectively arranged with local derviation rod 3, local derviation rod 8, and the arranged outside of one of them local derviation rod 3 has parent roll 1, and below between local derviation rod 3 and the parent roll 1, is provided with rouleau tube 2; The arranged outside of another local derviation rod 8 has uncoiler 10, and below between local derviation rod 8 and the uncoiler 10, is provided with parent roll 9.During practical implementation, described uncoiler is blank to be generally the thick pressure roller system that sends into of 15mm carry out once rolling; To expect when described parent roll band material is thick that volume is neat, for band provides tension force; To expect during described rouleau tube band material book that volume is neat, for band provides tension force; Described rectification roll can guarantee the roll line level, and measures mill milling speed; It is oil removing that described five pressure rollers mainly act on; The band template is by working roll and backing roll control.To the width of rolling material, be ground to double tapered to harmful contact zone, the both sides of corresponding backing roll, to the above milling train of 12 rollers, the one-level backing roll can be ground to two notch cuttypes, and working roll is disengaged in the zone outside bandwidth contacts with backing roll.Adopt this kind method, the lateral stiffness of milling train is big, the influence that the working roll amount of deflection is not changed by roll-force, template good stability.In the middle of the actual production; The width of band is not necessarily consistent; Can be divided into 2-3 type to the little product in batch of width difference; Formulate the size of grinding backing roll by the wideest product in dissimilar, when the band of rolling respective widths type, harmful contact area of backing roll and working roll can reduce greatly like this.For with band narrower in the width type,, reach the purpose of control template through adjusting the shape that little bending roller force just can change roll gap.
