Description
Technical field
The present invention relates to roll-bending device technical fields, more particularly to a kind of novel roll-bending device.
Background technology
Roller technology is to be bent roll barrel with mechanical force, to control strip profile (see strip crown) and glacing flatness (see flat
Straight degree control) technology.Usually using hydraulic pressure as power, therefore also referred to as hydraulic bending roll.Hydraulic bending roll goes out from phase early 1960s
Since existing, very rapid hydraulic roller-bending device developed and has had become essential equipment on various strip-mill strips.Hydraulic bending roll skill
Art can be divided into work roll bending and bearing roll bending two types.
As the ratio between working roll barrel length L and diameter D L/D<When 3.5, by the way of working roller bending；When L/D >=3.5
When, frequently with the mode of backup roll bending.It is divided into two kinds of roller modes just curved and negative curved.It is so-called it is just curved refer to bending roller force
Make roll generate bending direction and roll-force caused by bending direction on the contrary, i.e. roller when work roll crown increase.And it is negative curved
Refer to that bending roller force causes roll bending direction identical as bending direction caused by roll-force, i.e., roller when work roll crown reduce.
The just curved this roller mode of working roll is often by hydraulic cylinder on bottom working roll bearing block, hydraulic bending roll force effect
Between upper and lower axle bearing the number and size of hydraulic cylinders depend on required bending roller force size and roll bearing it is strong
Degree.2~4 hydraulic cylinders are housed generally on each bearing block.Hydraulic cylinder is replacing working roll in working roll bearing block
When need to dismantle pressure duct connector, use is very inconvenient.A kind of structure that comparison is new is to pacify the hydraulic cylinder of upper working rolls and lower working rolls
On rack boss, it is not necessary to which roller replacing operation can be carried out freely by dismantling pipe fitting.
Currently, the Chinese patent of Publication No. CN204182683U discloses a kind of novel roll-bending device, including on four
Roller bending block and four lower roller bending blocks with the cooperation of upper roller bending block, are arranged hydraulic cylinder, the hydraulic cylinder packet on every group of roller bending block
